Ma Dian couldn't help but stretched out his hand and explained: "You have to know that the dregs are a very important thing in the medicinal materials. Some medicines even only need the dregs, not the liquid, because the dregs are not the remaining things, but

It’s something that’s difficult to refine.”

"In the profession of alchemists, there is a popular saying: It is better to spend ten years grinding a cup of soup than to refine a hundred pills; it is better to leave the stove with a hundred herbs and water than to throw away half the ashes of the boiler."

"In many cases, the effect of medicinal residue is often more powerful than that of potion, but some lower-level alchemists cannot completely turn the medicinal residue into potion and cannot exert the medicinal effect of the medicinal residue. But even so, normal refining

The pharmacist will not throw away the medicine residue easily!"

Hearing this, Xin'er scratched her head in embarrassment, because just now, Xin'er threw away the separated medicinal residue.

"Turning medicinal dregs into potion is a process from quantitative change to qualitative change. Your method of throwing away the medicinal dregs directly is equivalent to abandoning qualitative change and only focusing on quantitative change. The efficacy of the medicine will naturally be much less. Press

With your method, ten ingredients may not be enough to make one medicine." Ma Dian explained.

After listening to Ma Dian's explanation, Xin'er lowered her head silently and said with some embarrassment: "Okay."

Ma Dian touched Xiner's head and said, "You should learn magic honestly now. I will teach you how to make medicine when you master the fire element or the wind element!"

"Really!" Xin'er raised her head excitedly, stretched out her little finger and said, "It's a deal!"

Ma Dian also hooked Xiner with his little finger and said, "It's a deal!"

In this way, Xin'er no longer thought about being an alchemist, but wholeheartedly helped Ma Dian grind the medicinal materials. Fortunately, it was Nie Haitang who delivered the medicine this time. In order to express his sincerity, Nie Haitang specially sent a lot of medicinal materials to Ma Dian.

, so that Xin'er won't waste a portion and then be unable to make medicine.

Among them, there are many precious medicinal materials that can be used to refine precious medicines, and Ma Dian also collected them in case of emergencies.

After an hour of grinding, a bowl of "Gui Qi Tea" was finally finished. The two of them stretched out at the same time and were about to take a rest. Suddenly, Xin'er felt a vibration in her chest.

I quickly took out the mirror in my arms and saw eight words written on it: Gather on the battlefield under the wall! Come quickly!

Ma Dian came close to Xiner, looked at the eight big characters, and couldn't help but frown slightly, "What's going on?"

Xin'er shook her head, "I'm not sure, do you want to go take a look?"

"It's so late, let's forget it. Who knows if that person named Yu has bad intentions?" Ma Dian said with some resistance.

"No, Miss Yu, she is not a bad person. If you call me so late, you must have made some important discovery, and you must tell me in person! No, I have to go take a look. Brother Dian, please stay here to avoid waiting for a while.

If someone knocks on the door and finds that we are no longer there, it will be difficult to explain then." Xin'er said calmly.

"How can that be done? If you want to go, we must both go together. I don't worry if you go alone. Besides, it's so late. There shouldn't be anyone knocking on the door." Ma Dian said.

"Okay, then let's go together." Xin'er nodded.

"But, there are soldiers patrolling our area, how can we sneak out?" Ma Dian was a little confused.

Xin'er smiled mysteriously, "Hey, Brother Dian, have you forgotten how I sneaked out with Sister Siyu and the others before?"

…

The night is already deep, and the moon is like a claw, drawing away the bright red sky and the dark yellow ground, leaving behind a faint moonlight, drawing a hazy figure in the dim sky.

The mountains and forests are like ink, the clear springs are dim, the breeze and night dance on the earth, taking away the dust, taking away the warmth, and even taking away the light that belongs to the day.

Within the wall, although you can't notice the night, you can still feel the silence of the night. Whether it is the third floor or the second floor, all rooms have their doors closed, and only a few people patrol the corridors, and their footsteps are very quiet.

They are light and have a very lazy look. They are all affected by the night, making them somewhat sleepy.

In this lazy moment, no one noticed that Xin'er and Ma Dian's room had been quietly opened and closed not long ago, and on the stairs not far from their room, there was a sound

The sound of slight footsteps echoed in the corridor, and soon disappeared, replaced by the sound of birds flapping their wings.

…

Under the wall, two people in black were standing, one male and one female, one tall and one short, one plump and one thin. At this time, they were clinging to the wall and constantly looking around.

If Xin'er were here now, she would definitely recognize these two people at a glance. They are Yu Ruxue and Shan Maoyan who Xin'er had met before!

Yamamahiko who was standing by could not help but take off the mask on his face, took out a bun from his arms and put it in his mouth.

Seeing this, Yu Ruxue on the side patted Shan Maoyan's hand hard and said: "Be careful! What if someone discovers you!"

Yamamahiko was in pain, hurriedly swallowed the buns, and quickly put on a mask.

"Sister Yu, is that Wumin really coming back?" Shan Maoyan said, rubbing the back of his hand that was slapped.

"Nonsense, I've sent her a message, she will definitely come." Yu Ruxue said while observing the surroundings.

"What message did you send her?" Yamamahiko asked.

"It's just like what I sent you. Gather on the battlefield under the wall! Come quickly!" Yu Ruxue said.

Shan Maoyan was speechless for a while after hearing this, "Sister Yu, have you been stupid since you haven't carried out missions with outsiders for a long time? The battlefield area under the wall is so big, and you didn't even give them the coordinates. How can they find you?"

ah."

When Yu Ruxue heard this, she patted her head and said, "Oh no, I forgot that she doesn't know how to locate the location. I have to send her the location quickly!"

Yu Ruxue was about to send her location to Xin'er when she heard a familiar voice coming from behind her.

"No need, I'm already here."

Yu Ruxue and Shan Maoyan turned around subconsciously, only to see Xin'er and Ma Dian already appearing behind them.

"Digging! When did you come? I didn't even notice you." Yu Ruxue exclaimed.

Xin'er had no intention of telling Yu Ruxue that she was carrying a heaven-defying treasure. As soon as she found out about Yu Ruxue, Xin'er took the handkerchief back.

Xin'er helplessly spread her hands and said, "Maybe our presence is too low."

Seeing that Xin'er refused to say more, Yu Ruxue didn't ask any more questions. Instead, she looked at Ma Dian and smiled charmingly: "Hey~ the little virgin is here too? Now that's good, we have another helper! After a while, you

You have to protect me well."

"Go away! Who wants to protect you? I'm warning you, don't be rude to Xin'er again, otherwise I want you to look good!" Ma Dian shouted to Yu Ruxue.

Upon hearing this, Yu Ruxue couldn't help but raise the corners of her mouth, licked her lips and said, "Hey, if I don't do it to Xin'er, is it okay for you?"

"Get lost!" Ma Dian turned his head instantly and said with a red face.

Shan Maoyan on the side saw this and couldn't help but cough twice, "Ahem, I say Sister Yu, it's time to talk about business."

Yu Ruxue then put away her smile, nodded and said: "Okay, okay, I understand."

"You two, you don't need me to introduce this guy." Yu Ruxue pointed at Shan Shigehiko and said.

Xin'er and Ma Dian smiled slightly. They recognized Shan Maoyan the moment he opened his mouth, and they cupped their hands in front of him and said, "Brother Shan Maoyan! Please give me some advice!"

Shan Shigehiko also cupped his hands towards the two of them and said, "Please give me more advice."

"Okay, let's get down to business. Let's talk. Sister Yu, why did you ask me to come out so late?" Xin'er asked.

Yu Ruxue looked around, bent down, and motioned for Xin'er and Ma Dian to come closer. The four of them formed a circle, and then Yu Ruxue said: "Xin'er, didn't you tell me before that you asked me to go to other areas to take a look?

?”

"Well, could it be that we have already passed by?" Xin'er asked in surprise.

Yu Ruxue nodded and said: "Well, not long ago I just went with Xiaoshan to look around the nearby No. 6 area and found..."

When Xin'er heard this, she couldn't help but interrupt Yu Ruxue: "Wait, wait, how did you get to Area 6? How on earth did you escape from the underground prison? I'm very concerned about this.

Curiosity.”

Yu Ruxue smiled slightly, "Because I participated in setting up the cage on the underground level of Kaming Wall."

"What? You also participated in setting up the underground prison below?!" Xin'er exclaimed.

"Isn't it strange? After all, the main prisoners here are some frontier warriors who may rebel and some Jianghu elements. In order to ensure the stability of the prison, the emperor specially invited the top ten generals at the time to set up underground prisons. As a person, I

One of them, once you know the setting up of this prison, and even more about its mechanisms, as long as I trigger the mechanism and make the two guards who are guarding me fall asleep, it will not be easy to figure it out." Yu Ruxue looked calm.

road.

"By the way, Xiaoshan is the chief designer of 80% of the prisons in our empire. The prison here was also designed by him as the chief designer." Yu Ruxue added.

Xin'er looked at Yu Ruxue and Shan Maoyan, and she was already extremely surprised: I didn't expect that these two people actually have such identities, and that such outstanding two people were actually sent as spies. It seems that Zhu Wenxuan is really interested in Ye Chang.

Pay attention!

"Haha... you two... are really powerful." Xin'er said with emotion.

Yu Ruxue shook her head lightly, "Okay, let's get back to the subject. After Xiaoshan and I checked the battle site in Area 6, we found that the soil in the area where the corpses were buried had some strange texture. The soil there was not loose.

, on the contrary, it is very tight.”

"Out of curiosity, I dug it up and took a look. I found that all the buried corpses had turned into bones! Moreover, there were black maggots growing between the bones! I guess that's what you mentioned to me before.

Got some clues?"

Xin'er nodded, "Yes, black maggots are a unique product of the Yanyan Sect. Therefore, I guess that this beast tide is probably caused by the disciples of the Yanyan Sect, and those two Yanyan Sect

The disciple is currently hiding in a corner of the forest, observing every move on the wall!"

As she said this, Xin'er subconsciously looked towards the dark forest, only to feel that there was a pair of eyes staring at her among the swaying leaves.

Shaking subconsciously, Xin'er quickly turned her head and heard Yu Ruxue ask: "Wait a minute, how do you know there are two people from the Yanyan Sect hiding in the forest?"

"Because I have seen them before!" Xin'er said solemnly.
