Zhang Qian was thinking hard for several nights, how to write a quatrain poem to communicate so as not to show fear on the spot. For several nights, all he thought about was that the poem could not be written, and the difference between the level and the upside was too much, and how could he think about the problem of not being in a state of mind? At this moment, Zhang said that this expert in literary and political circles revealed it in one sentence, and suddenly realized that the biggest problem of the chrysanthemum poem he had compiled was not the level and the upside, but the feeling was too disappointing! There was no young man that he should have!

In turn, compare Wang Han's sentence, "Where is the lotus on the stream now? The wild chrysanthemums by the fence laugh at the autumn wind...". Both sides are at least forty years apart in artistic conception. One is a sunny boy and the other is a white-haired old man!

Just as he was so embarrassed that his sweat was rising, he heard He Zhizhang take the initiative to defend himself: "Why should Daoji be too harsh? Young people are sad about spring and autumn, and their white hair is full of passion. Isn't it the common sense in the world? When He was twenty years old, many of the words he wrote were several times more decadent than this song of chrysanthemum. However, now he is nearly fifty years old, but he often makes some bold words to hide the dusk in his heart."

"This is very true!" Wang Anzhi was about the same age as He Zhizhang, and he also smiled and spoke next to him. "While I read this poem, although there are slight flaws in the tone and the artistic conception is a bit depressed, it is much higher than the works of most young people in the Imperial Academy!"

"That's natural, otherwise, how could Weng Ji bring him to us!" Zhang Shuo didn't argue with He Zhizhang and Wang Anzhi, and nodded slightly with a smile.

"If you two knew that he wouldn't even say Tang Yan more than a month ago, I'm afraid that his views on this poem would be very different!" He Zhizhang was still dissatisfied and continued to make every effort to stand up for Zhang Qian. "Besides, his master was not originally known for his gorgeous articles."

"Ah?" After the words came, Zhang Shuo and Wang Shi were shocked. Even Bi Gou, the oldest, was shocked, "Be serious? He really didn't say Tang Yan a month ago?"

"He came out of the mountain for less than two months. When He saw him for the first time, he was still talking stuttering!" He Zhizhang smiled and nodded slightly. Then, he hesitated for a little while and quickly added: "The Mo family has been good at making tools since ancient times. The last time He went to his house to get wine, he had seen the copper pot he made of wine, which was so skillful. Both of them had used the emperor's herders in the area. If they were to use various utensils in the future, they might as well send someone to consult Yongzhao."

"Making instruments? Have you really learned the secret techniques of the Mohist school?" Zhang Shi raised his eyebrows, and two sharp lights immediately ejaculated in his eyes.

"How much have you mastered using Zhao, the secret technique of the Mohist school? Can you show me one or two?!" Bi Gou is old and has a little slow reaction, but he looks at Zhang Qian again with a knife-like gaze, his face full of disbelief.

It's not their fault that they are suspicious.

Since Lu Zang used the two "smart people" of Lu Zhengming and his brother Lu Zhengming to become famous by living in seclusion in Zhongnan Mountain and "avoiding the world" and successfully intervened in the ranks of high-ranking officials in the Tang Dynasty. Every year, there are many hermits and strange people who appear near Chang'an every year.

The top scholar He Zhizhang, who is well-known for his favorites, often uses some excessive words to make a name for his favorite younger generations. (Note: He Zhizhang has praised many people, the most famous of whom is praise Li Bai and the exiled immortal.)

Therefore, whether Wang Shi, Zhang Shuo or Bi Gou, he did not take Zhang Qian's identity as a disciple of the Mo family seriously. He just hindered the face of He Zhizhang and Zhang Ruoxu, and followed him with a few words. Anyway, inside and outside Chang'an City, young people who were looking for the car with various strange signs were not inferior to Zhang Qian.

Now, He Zhizhang put aside his fancy articles and directly mentioned practical instruments. Bi Gou and Zhang Shuo did not dare to do anything perfunctorily anymore. After all, as long as you are willing to spend money, you can find experts to catch the knife. However, the Mohist institutions have to make a real or false effect. If they are true or false, they can distinguish clearly by using them!

"To use Xiaoyou Zhao, anyway, the guests have not arrived yet. You might as well say a few sect objects to let them two ignorant guys have a better understanding!" He Zhizhang was so smart that when he heard Bi Gou and Zhang's question, he immediately guessed that the two of them did not believe that they would introduce Zhang Qian first. He immediately felt angry and asked Zhang Qian with a smile.

Zhang Qian originally wanted to be modest, but now he found that the matter had already involved He Zhizhang's face and reputation, so he did not dare to disappoint those who were wholeheartedly good to him. Therefore, he took a step forward, grabbed a pair of chopsticks from the table with a smile, and gestured, "I dare to teach you seniors that after Qin Mo entered the mountain, he was unwilling to work hard on killing weapons. Therefore, he learned very little in terms of weapons. However, the objects that can be used to improve people's livelihood have been slightly involved..."

As he spoke, he raised his chopsticks as pillars, and took a seven-panel containing fruit as a gate. He quickly demonstrated: "Please look at it, this is the general appearance of a one-way water gate. I saw that many lands around Chang'an were affected by floods. If you dig a canal and connect it to the river to drain water, you need to beware of the river backflow. If you build such water gates on the canal. When the water level in the farmland is high, the gate will be pushed open by the flood, and the water can leak into the river on its own. When the river water surges, push the gate backwards and closes the gate. At that time, there will be no drop of river water and can be poured back into the farmland!"

As the saying goes, experts will know if they have any. Bi Gou was sent to another place to be the governor of the powerful ministers a few years ago because he offended the powerful ministers and slandered his colleagues. Zhang said that Wu Zetian kicked to Qinzhou, Lingnan by Wu Zetian. When these two local officials were local officials, they often scratched their heads because of floods. Now when they saw Zhang Qian's one-way gate, how could they not understand the magical use of this thing? For a moment, many feelings such as surprise, shame and annoyance came, and they both wanted to stand up and grab the ground with their heads!

What’s surprising is that with this gate, most floods and disasters can be solved easily.

What I am ashamed of is that such a simple wooden door, I have been thinking about it for many years, but why can’t I think of it?

I was even more upset that I was returning to Chang'an to report my work, but I couldn't afford to give me enough money to give gifts to Empress Wei's brother. I wanted to make up for the actual flaws. I don't know when I will wait? Seeing the powerful weapon that can benefit the people, I can't promote it myself. So what's the difference between not seeing this thing?

Zhang Qian didn't know that the technological progress of the window paper in the eyes of later generations was a mountain for his predecessors! He felt that just taking out a one-way water gate was not enough to compete for He Zhizhang. He put down the chopsticks and Qipan, and asked the servant for a set of paper and pen, quickly drew a windmill and a simple pipe-type water pump.

"Several seniors have seen these two objects? This is a windmill. The younger generation calls it a well below. If you use a windmill to drive the shaking handle of the well, you can continuously draw water from the lower part to the higher part. If you build a dam between the ditches and the river, set the windmill on it, and connect a bamboo pipe to make a well pipe. During flooding, you can drain the water in the ditches, use windmills and machine wells to drain it into the river. In drought, you can lift the water in the river into the ditches. In this way, unless you encounter a disaster of thousands of miles of land or flooding, small droughts and floods will basically not hurt the people on both sides of the river!"

After the words "hiss" came, the four elders present, widened their eight eyes and sucked in the air. Even if they were calm, they could not say a complete sentence.

Windmills are not new to them who are knowledgeable. However, it is unheard of them to use windmills and two pipes to draw water from both sides of the dam.

As for the "machine well" in Zhang Qian's mouth, why does it have such a magical function? What is the reason? He has never even dreamed of it even if he heard of it!

Zhang Qian was afraid that the four of them would not believe it, and smiled and continued to add: "Many places in the villages of the younger generation have suffered from floods this year. Therefore, taking advantage of the high and cool autumn weather, he specially ordered the housekeeper to organize servants and tenants to dig canals, build embankments and select places to set up water gates, windmills and machine wells. It will take about a month and a half before the windmills and machine wells can be done. But several water gates have been installed. If the four seniors are interested, they can go to the villages of the younger generations to see these things with their own eyes."

"This..." Bi Gou, He Zhizhang, Zhang Shuo and Wang Shi finally stopped inhaling. He stared at each other with eight eyes widened and saw the unconcealable madness from each other's faces.

If water gate, windmill and machine well could appear in the world and be promoted. The surrounding Chang'an City surrounded by eight waters would probably produce hundreds of thousands of acres of fertile land out of thin air! And Gunzhou, Xiangfan, Gusu, Yuhang and other places that are even more flooded than Chang'an, may all become a land of fish and rice, and a paradise on earth in time!

After a long time, Zhang said that he was the first to recover. He pointed at He Zhizhang's nose in a rude manner and complained loudly: "Brother Ji Zhen, this is your fault! With such a powerful weapon and a genius, why not offer to the emperor as soon as possible?! Zhang knew that you cherish your feathers, but compared with the welfare of the people in the world, just feathers are a bullshit!"

"I, it's the first time I have seen these three magical artifacts today!" He Zhizhang was scolded so much that he was wronged, and blushed and defended himself loudly, "If I had seen Mizuno, Windmill and Jijing when I first met him, how could I recommend Yong Zhao?"

"Mr. Ji, Daogong, don't argue, two seniors, please listen to me!" Seeing that He Zhizhang and Zhang were about to argue like children, Zhang Qian quickly persuaded him to fight: "Shuimen, Fengmill and Jijing, I was in the master's sect before, but I had not done it myself. Therefore, before the performance of these three objects was confirmed, I dare not make them public. When Senior Ji Weng was a guest at the junior village, the younger generation had not yet made the real objects, so I didn't tell him. Now, these three objects have been almost done, so I dare not treasure them anymore."

"Well, it's important, it's definitely better to be cautious." Bi Gou was the oldest, and he stroked his beard with his trembling hands, and made a final decision.

"Then go and make it quickly, create the real thing one day earlier, and benefit the people one day earlier!" Zhang Shuo was still unwilling to give up, and his eyes were red and urging loudly. "If it is really as you said, even if the performance is half worse, you don't have to go everywhere. Long Weng, Ji Weng, An Zhi and me will work together to protect you a fame and fortune!"

The word "submitted" means in the Tang Dynasty to send your articles to high-ranking officials and nobles in order to help them become famous or to recommend themselves to enter the official career.

Zhang Qian understood the meaning of these two words, and even more so. Zhang said that he took out the chrysanthemum poem and asked He Zhizhang to correct it as "submitting" to the four elders. He suddenly felt that it was necessary to clarify it, and blushed and explained in a low voice: "Thank you, senior. However, I dared to teach you that senior that I had learned that the previous poem was really wanted to give advice from Senior He, not..."

"Okay, I know you don't mean to submit the paper. However, I have the responsibility to not let the pearl be buried in the dust!" He Zhizhang rolled his eyelids impatiently and interrupted.

"Why are you so timid at such a young age?" Zhang Shuo also glared at him fiercely and whispered, "The Tang Dynasty tolerate all over the world. People with abilities never need to hide it and pretend to be modest! Since you are lucky enough to practice a magical technique, it is natural to take it out to serve your parents' country! Do you really have to live in the forest until your hair is gray and you will feel great again, just for the flowers to bloom late, and you will not be able to repay the spring breeze?! You just said that you are aging before you grow old, but you are not convinced! Humph, this time Zhang caught a right now!" Please, please vote. I am tired and paralyzed, and the second update will be presented.
