Zijuan walked in with a pot of hot tea that had just been boiled, and poured tea for Zhang Qian and Luo Huaizu. The palms of some girls, which had a little bit of shiver, were trembling slightly uncontrollably.

"Go down and rest, there is nothing wrong here!" Zhang Qian could feel the tension in her heart, and smiled and tapped the table with his fingers.

"Yes!" Zijuan obviously understood his hint, but there was still a trace of unconcealed worry in her eyes. She squatted and saluted, walked out carefully, and gently closed the door of the outer room.

Zhang Qian knew what Zijuan was worried about, so he smiled, picked up the hot tea, and continued to drink it slowly. The tea water reflected his own tired but still firm face.

For people like Luo Huaizu, he wanted to fight, but couldn't beat them. He wanted to chase them, but he couldn't drive them away. He wanted to kill them, but he was not sure of success in one go. Once he killed this person and did not die, he was fled by this person. Next, the men, women, young and old in Zhangjiazhuang would all become the targets of this person's revenge.

Therefore, the most appropriate way now is to find a way to stabilize the other party first, and then take a step by step.

After being together for so long, Zhang Qian no longer had no idea about Luo Huaizu like when he first came into contact. Apart from the evil deeds accused by Zijuan, Zhang Qian had roughly explored some of the styles of this person's behavior, thinking context, and living habits. And the more he touched, the more he believed that this person was a crazy believer in the Mohist school.

Unlike Zhang Qian, the fake senior brother Qin Mo, who just copied the meaning of the Mo family and put it in the study, and only held the Buddha's feet when needed. Even when Luo Huaizu concealed his whereabouts as a second account room in Zhangjiazhuang, he still tried hard to abide by the behavioral standards of the Mo family's children.

Logically speaking, this guy just robbed the White Horse Temple in Qujiang, and even the monks used the account book to lend money to the high interest rate, so he would not ignore the wealth in the temple. However, this man still had cloth shirts and shoes in winter, and there was no silk cotton fur on his body. He usually went to the kitchen to get food, but he knew that he could enjoy the treatment of a accountant, but he only took one meat and one vegetable for each meal. The house he lived in didn't need to be cleaned by the servants, and he always cleaned it up spotlessly. Although his attitude towards the servants was cold, he was never arrogant.

When talking to Zhang Qian, the emperor of the Tang Dynasty, the dignitaries and celebrities, this person did not have any respect in his words. He was so disrespectful that sometimes Zhang Qian even began to doubt whether this person was like himself and traveled through other time and space? Especially for the Emperor of the Tang Dynasty, Li Xian, Zhang Qian himself could not completely look at him. However, every time he raised this person, the contempt on his face was changed.

However, when facing Guo Nu, Ren Cong and even the butler Ren Quan, Luo Huaizu would quickly switch to another face. Respect, polite, polite, and every move shows the closeness of his family, making the other party feel like spring breeze. If it weren't for the sudden appearance of this person and Zhang Qian's attitude towards this person was too cold, it would be easy for Guo Nu, Ren Cong and Ren Quan to mistake him for a distant elder of Zhang Qian, and then open the door to convenience for him in all matters.

In order to avoid Guo anger, Ren Cong and Ren Quan were deceived by Luo Huaizu's behavior, Zhang Qian had specifically emphasized that Qi Mo and Qin Mo were not one. Both sides have established their own businesses for more than a thousand years, and their relationships are farther than when they walk in Chang'an City and meet a stranger named Zhang at this moment.

Guo Nu, Ren Cong and Ren Quan confirmed Zhang Qian's attitude, so naturally he did not dare to get too close to Luo Huaizu. However, Luo Huaizu found Zhang Qian in a furious manner and asked him why he deliberately made the relationship between the two families so distant. Zhang Qian's response was to smile without answering.

As a result, this person quickly inferred some clues from Zhang Qian's daily behavior. He explained with strikingly that none of the people he killed before was innocent. Officials, officials, monks, Taoists, priests, and priests were all full of evil deeds. Killing them or using them by themselves is just a fairness in the world.

"Don't forget, Master Luo, Zhang is also a high-ranking official now!" After hearing the other party's fallacies, Zhang Qian bluntly pointed out his current identity at that time.

However, Luo Huaizu still announced with striking remarks. Zhang Qian was the senior brother of the Mo family, and becoming an official was a means to revitalize the Mo family, which was completely different from other officials just for glory and wealth.

"You can't kill all the officials in the world. In this world, someone will come out to take charge of the matter." Zhang Qian was so amazed and laughed and decisively pointed out the omissions in the other party's words.

Luo Huaizu responded with a smile at that time, "Don't destroy or establish." Now that the officials are dead, the Mo family will be better carried forward, and the Mo family pursued a more chance to realize the world of love.

…………

As a former philosophy graduate student, Zhang Qian firmly believed that no matter what religion or political concepts, ordinary people would be better off staying away from them. Such people are prone to becoming saints and monks, and easily becoming madmen. The emotions and desires of mortals are very weak in them, and even if they have them, they cannot control their actions.

Such people show kindness or anger to you, in most cases, are disguised, completely serving their ultimate purpose, and can switch as needed at any time!

"I have no malicious intentions towards you!" Sure enough, I found that whether it was to persuade the revitalization of the Mo family or threaten Zhang Ruoxu's life safety, the purpose of holding the academy in my hand could not be achieved. After repeated consideration, Luo Huaizu began to change his tactics.

"I have no malicious intentions to you!" Zhang Qian put down the teacup and responded with a smile, with a look as honest as possible.

"I and you are both children of the Mo family." Luo Huaizu also put down the teacup and reminded him solemnly.

"Zhang and Zhang Shishu both have surnames Zhang." Zhang Qian smiled and emphasized very seriously. "It is said that as long as they have the same surname, they will not be too far away from each other after five hundred years."

"You..." Although it was not the first time that Zhang Qian said this, Luo Huaizu was still angry and his eyes were full of fire. However, he knew that he was angry and could not threaten Zhang Qian at all. He gritted his teeth and forced the anger in his stomach, and emphasized again: "Martial arts are my Qi Mo's skills in sect control. If you ask me to go to the academy to teach shooting and storm, it is equivalent to making my Qi Mo's unique skills public."

"You can just teach some fur so that students can ride horses and drive bows, so as not to become nerds with weak hands and feet, and there is no need to teach your unique skills in the town!" Hearing the bargaining taste in the other party's words, Zhang Qian responded with a smile, "Other teachers only teach one course, with a monthly salary of four hangs. Each of the shooting and Yu count one, with a total monthly salary of eight hangs."

"Isn't that higher than the county magistrate? You're crazy!" Luo Huaizu was shocked and blurted out his questions. However, after thinking, Zhang Qian's money for running the school was all the compensation from the monk, and he immediately lost his temper. He gritted his teeth and added in a low voice, "Since someone calls him Master, you can't fool it with fur. I can follow your arrangements and teach the two techniques of ejaculation and control, but it's too unfair to me to just get a monthly salary." (Note: One thousand yuan is a standard algorithm in the notes of the Ming Dynasty. Some readers insist on one hundred yuan, but lack verification. Please forgive me for not being able to adopt it.)

'You can just be willing to bargain.' Zhang Qian felt relieved in his heart, but he deliberately pretended not to understand the other party's meaning. "This is the highest moon. The mountain leader only has ten monthly salary, and the mountain leader may not be willing to accept it."

"I'm not talking about money." Luo Huaizu suddenly felt insulted and looked angry. However, soon, he discovered that if he continued to talk like this, he would definitely become more and more passive. He decisively made up his mind and asked for a price everywhere. "I can teach me Qi Mo's masterpiece, and even teach you step by step. However, you have to exchange the formula of the black medicine powder filled in the copper bell and clay pot that day. As for the monthly salary, I can take no money!"

"Uncle Master, what's the name of the other weapon on your waist?" He had long expected that Luo Huaizu would never forget the recipe of black gunpowder, so Zhang Qian glanced at the man slantedly and whispered a reminder.

"Measure the Libra!" Luo Huaizu gave the answer immediately without thinking. Then his face turned red again.

The Mohist school used the measurement of the scale as the order, which means that fairness is its responsibility. Luo Huaizu used the teaching of students' martial arts to exchange for the "magical medicine" formula in Zhang Qian's hands that could break the altar a hundred steps away, and there was no difference between the two. The two were not equal at all, at least in the Tang Dynasty in the eighth century, which was completely unequal. This exchange was completely contrary to the Mohist philosophy.

"You have a monthly salary of eight, at least you have a serious job to hide your identity. The academy was given by the emperor himself. It is a bad person in the Tang Dynasty. I guess he would not have the courage to go to the academy to verify the life of every teacher." Seeing Luo Huaizu's face all, Zhang Qian continued to state the benefits of being a teacher.

When dealing with a crazy believer or a saint, you cannot talk about any relationship. The easiest way for both parties to exchange their interests directly with reason.

Sure enough, when he heard the four words "covering identity", Luo Huaizu's face changed slightly. Then, he sneered and shook his head, "I don't need to cover up my identity. If I want to leave, which bad person in the world can stop me? As for your medicine powder, I advise you not to cherish it yourself. I have checked the materials and exits of your house some time ago, and saltpeter and sulfur are not decimal."

While talking, he observed Zhang Qian's face, hoping to see some emotional fluctuations. However, when he heard the words saltpeter and sulfur, Zhang Qian just shook his head and smiled. "Since my uncle can find out that my family has purchased a large amount of saltpeter and sulfur, I guess it's not too far from finding the formula for the medicine powder. If you continue to explore, Zhang will never stop you, nor will he trade with you with the formula, so as not to think that Zhang will be blackmailed later."

"There must be saltpeter, sulfur, and the proportion of portions is about ten to two." I don't believe that I didn't even touch the edge of the secret recipe. Luo Huaizu gritted his teeth and continued to add ingredients. "Since the powder is black, I can only find the black stuff from the black stuff, Baicao frost (the bottom ash of the firewood pot), lead powder, black soil, etc. It may not be difficult for me to try it in the sample! And to prepare this medicine, it is impossible to have more than seven kinds of materials. I have got the third of the seven kinds, so it is easy to find the other kinds."

When Zhang Qian heard this, he smiled slightly again, and simply picked up the teacup and drank water, and stopped answering the person's words.

Not to mention that Luo Huaizu did not expect that black gunpowder actually contains three ingredients, and the third ingredient is an extremely common charcoal powder. Even if he speculated the charcoal powder, it was still hundreds of years away from estimating the actual combat power ratio of black gunpowder.

You should know that in another time and space, it was at least seven hundred years since Sun Simiao discovered the prototype of black gunpowder in the early Tang Dynasty, the "Sulphur Fire Method" to the basic model of black gunpowder in actual combat in the late Yuan and early Ming Dynasty. However, when the maximum power ratio of black gunpowder was discovered, it was at least nine hundred years. (Note: Sun Simiao discovered that gunpowder was used as explosive agent in the early Tang Dynasty, that is, from 618 to 630 AD. It was used as explosive agent in the late Yuan and early Ming Dynasty. In the Song Dynasty, it was only used as a burner. Black gunpowder was close to the best ratio, which was Qi Jiguang's anti-Japanese war era, after 1550. The best ratio of black gunpowder was officially proposed in writing, in 1635.)

Therefore, the more Luo Huaizu said, the more Zhang Qian felt at ease. Later, he simply poured a cup of hot tea for Luo Huaizu, indicating that this person could moisten his throat first and then continue.

Now, Luo Huaizu was hit hard. He pushed open the teacup, grew up, took out the measuring scales, flying knives, sleeve arrows and other objects from different positions on his body, and threw them one by one on the table. "Your black medicine is of great use to me. What do you want me to exchange for you? Just offer the price. Liangtianzhu and these life-saving weapons, Qi Mo, and even my husband himself, will be open to you!"

"Uncle Master, you have such a high martial arts skills. Who do you want to kill? Can't you use my black medicine powder?!" Unexpectedly, the other party could even make the cruel decision to sell himself as a slave. Zhang Qian was stunned and asked slowly.

"If I want to kill, you don't have to worry about it. Just give me a happy word, change it, or not?" Luo Huaizu was rarely impatient and asked with gritted teeth, "I can add a hundred taels of gold, five pairs of jade bi, and three dou of pearls. Each pearl is the size of a cherry and has no flaws on the surface!" (Note: What we are talking about is the native Chinese cherries, not cherries.)

"So Uncle Master, you are so rich!" Zhang Qian looked up and down at Luo Huaizu's clothes, and no matter what, he did not match the person with the wealth he reported.

"I told you serious things!" Luo Huaizu was so angry that he rolled his eyes, but knew that getting angry had no effect. "I am the head of Qi Mo. I have to set an example for the Mo family all over the world. Do you change it or not? I think it's not enough, I can add it!"

"No!" As if he was afraid that he would not be angry to death, Zhang Qian shook his head with a smile. "I am not short of money. With your skills, you cannot get close to me. You still need to use black medicine powder to assassinate. Your official position may not be lower than the fourth rank. I cannot cause disaster for myself!"

"That guy has a lot of blood and debts on his hands!" Luo Huaizu was so angry that his body began to tremble, but he tried hard to control himself and strangled Zhang Qian to death. "I killed him to seek justice for those who died in vain because of him. I don't need your bronze bell, I only need your black medicine. I throw it with my hand and can throw the medicine jar thirty steps away. So far, only five people know the black medicine, and the court will definitely not suspect you afterwards!"

"Not changing that!" Zhang Qian thought for a while, continued to smile and shake his head. At the same time, he quickly stood up from the chair and retreated decisively, "Uncle Master, stop! Otherwise, there is nothing to talk about!"

"You" Luo Huaizu, who had already pounced on him, tried hard to hold his body, and sparks were almost emerging in his eyes.

"Five years!" Zhang Qian had already tested the other party's thoughts and knew that he could not continue to anger the person. He smiled and raised his palm, "Five years later, before you go to Tianzhu, I will give you a recipe. Within these five years, you will go to the academy to teach students the ejaculation and the two techniques. You can grasp the level of teaching yourself, and I will not interfere. In addition, you must agree to be sent by me and do your best!"

"You think beautifully! Five years have passed, enough for me to figure out the recipe by myself!" Luo Huaizu opened his teeth and looked dissatisfied.

Zhang Qian smiled and walked back to the table to continue drinking tea. Seeing this, Luo Huaizu suddenly lost confidence and gritted his teeth and continued to bargain: "Five years are only five years, but when I leave, I need to take away a bronze bell. In addition, you must pay as much as the monthly salary!"

"Trade! But the bronze bell is not allowed to be used in the territory of the Tang Dynasty!" Zhang Qian smiled and gently raised his palm.

"Yes!" Unexpectedly, Zhang Qian agreed so happily, Luo Huaizu was stunned for a moment, and then quickly reached out to slap him in a high-high manner. It seemed that Zhang Qian would regret it a little slower.

Zhang Qian smiled and picked up the tea, and continued to savor it slowly.

Luo Huaizu finally got what he wanted, no longer talked too much, bowed his hand and said goodbye. In a blink of an eye, he disappeared into the darkness outside the door.

Hearing the footsteps outside the door getting farther and farther away, Zhang Qian put down his teacup again, clenched his fist with one hand, and waved it in the air.

He finally temporarily stabilized the safety hazard of Luo Zheng Sect. Although he spent a lot of effort and even applied the formula of gunpowder, five years have been enough for him to figure out the granulation method of black gunpowder. Compared with the ungranulated black gunpowder powder, the former has increased by at least 30% in terms of stability and power.

In order to strengthen his grasp of rescuing Yang Qingqing from the team, he really needs a master with strong martial arts skills around him. Luo Huaizu just meets this requirement.

"Senior Brother, can I and my junior brother come in?" A low call suddenly sounded outside the door, with unconcealed nervousness.

"Just come in!" Zhang Qian frowned slightly, and quickly figured out why Guo Nu and Ren Cong came uninvited in the middle of the night.

The door was gently pushed open, and Guo Nu and Ren Cong, covered in armor, walked in quickly. There were dozens of servants in the shadow behind them. Obviously, Zijuan went out just now, not only burned a pot of tea, but also quietly moved a rescue team.

"Senior brother, do you want us to block the room where he sleeps..." After gently cutting, a cold light suddenly appeared in Guo Nu's eyes.
Chapter completed!
