At the same time that the sorghum is rejoicing in the restoration of his white body.

North, Qingjian County.

A scholar named Zhao Sheng was reading at night in the Petroleum Temple.

Zhao Sheng has failed many attempts, has not been able to achieve fame, and has not become an official, but his character is not bad, and whenever the nearby villagers want to ask him to write a letter to the family, help read the list or something, he will help.

When he has free time, he will tell some stories from books to the nearby villagers, which is deeply loved by the people.

That night, he was reading a book in the Petroleum Temple and was fascinated by it, when a little monk slipped in and said eagerly: "Mr. Zhao, run!"

Zhao Sheng: "? ”

The little monk said in a low voice: "The government sent someone to bring you, and some people falsely rumored that Mr. lit the lamp in the lonely temple at night, and it was like the Huang Chao depicted in the plain story to create a military book and rebel....

Zhao Sheng was taken aback: "Why do you say this." ”

Little monk: "It doesn't matter how you came, run away, the people from the government are coming soon."

It turned out that the limelight on the side of Qingjian County was already very tight, and there were people everywhere in Shaanxi counties who rose up to make trouble, and the nerves of the government collapsed tightly.

Zhao Sheng gritted his teeth, damn it, I just want to study hard, the next time I participate in the imperial examination, be nominated for the gold list, and glorify my ancestors, why do you want to do this to me?

He quickly packed up his books and escaped through the back door of the Petroleum Temple.

fled all the way to Jiejiagou, and a large group of officials chased after him from behind.

Zhao Sheng is just a weak scholar, the kind whose limbs are not diligent, where can he run past the officials, and he is about to be caught, when he suddenly hears the thunderous shouts in the four fields, and a large number of ordinary people are holding hoes, wooden sticks and other things to kill.

"Damn the government, don't do anything to Mr. Zhao!"

"Mr. Zhao is a good person, you don't distinguish between right and wrong, and slander good people."

"Lao Tzu is the opposite today."

"Kill these servants."

A large number of ordinary people poured out, instantly crushing the officials into children's powder.

In the first year of Chongzhen, at the end of April, early in the morning.

Li Da rushed out of the blacksmith shop, holding a small spring in his hand, and laughed loudly: "Hahahaha, it worked, I finally succeeded, the elasticity of this thing finally recovered, hahahaha, I succeeded."

Li Daoxuan, who had just gotten up and was sitting by the box and nibbling on glutinous rice balls, couldn't help but be attracted by Li Da's attention and hurriedly looked over.

I saw Li Da running quickly to the bottom of the watchtower, not daring to go up, and raised his head to the third floor and shouted: "Holy Maiden, have you gotten up?" Look, look at this. ”

I saw Gao Yiye poking his head out of the balcony.

Li Da immediately put the spring between his palms, pressed it hard to the middle, and then released it, and the spring bounced away again.

"Look, I succeeded, hahaha, I succeeded."

Gao Yiye has no dark circles under her eyes, and in recent days, Li Daoxuan has called her as little as possible, so that she has more time to paint during the day, so that she can sleep well at night.

She smiled and watched Li Da finish the performance, and said, "Uncle Li, it's useless for you to show me this, I can't understand it, but don't worry, Tianzun has already seen it." ”

Li Da said loudly to the sky: "Tianzun, you saw it? I...... I did it....... I boiled it red and quickly put it in cold water. It's a little more resilient, and although it's not as elastic as it used to be, at least it won't flatten as soon as it is pressed. ”

Li Daoxuan thought to himself: You inadvertently discovered the "cooling method", which is very good.

However, his method is still very rough, and there are more detailed steps in the cooling method, Li Daoxuan has already checked it, but he is not in a hurry to give it to him, and wants him to think more about himself.

"Do you know why you can regain some elasticity after being burned red and then put in cold water to cool it quickly?

"No...... I don't know. Li shook his head.

Li Daoxuan sighed in his heart: Just like most of the ancient technologies of our dynasty, I only know what it is, but I don't know why it is. Alas!

You know that water turns into gas when it is boiled, but you don't know that when water is heated, the heat energy of the water molecules increases, which increases the average kinetic energy of the water molecules...... So even if you know that water turns into gas when it is boiled, you still don't understand anything.

You know that the spring will regain elasticity after rapid cooling after it burns red, but you don't know that the cooling method will make the atomic spacing smaller and the internal stress will increase, so that the spring will regain elasticity.

You get it, but you don't understand it.

It's all because of the lack of basic science!

Li Daoxuan said in a low voice: "Yiye, go and call Ma Daochang." ”

After a while, Ma Tianzheng came, he was different from ordinary villagers, as soon as he heard that Tianzun was summoned, he immediately had a red face, and when he arrived at the watchtower, he bowed down to the highest Taoist priesthood: "Disciple Ma Tianzheng, obey orders here." ”

Li Daoxuan: "Li Da, put the spring in Ma Daochang's hand." In addition, go and get another bag of cement and give it to Ma Daochang.

Li Da hurriedly complied.

Ma Tianzheng was holding a bag of cement and a spring, glanced left and right, and looked at the things in his two hands with a blank face: "I don't know what Tianzun commands, disciple...... I can't understand it. ”

"There is an honorable and difficult task entrusted to you." Li Daoxuan: "Take these two things and go to the Waxi archway in Fengxin County, Jiangxi, where there is a scribe named Song Yingxing, who has repeatedly failed the scientific examination and is a little suspicious of life." After you find him, put these two things in him

In his hands, show him the elasticity of the spring, and then teach him how to use cement.

Ma Tianzheng said: "It's just a trip to Jiangxi, it's not difficult for the disciple, it's really not arduous, the disciple will set off."

Li Daoxuan: "Well, go ahead!" Be careful all the way. ”

Ma Tianzheng said: "The disciple will also protect these two divine objects with his life. ”

Li Daoxuan shook his head: "Protect yourself, if you lose these two things, you can go back to Gaojia Village to get them, if your life is lost, then it will be gone." ”

Ma Tianzheng was grateful: "Tianzun is benevolent, and the disciple's skin is not worth mentioning." ”

He hurriedly packed his bags, tied his leggings, brought dry food, and solemnly hid a small bag of cement and springs, and then left Gaojia Village and headed for Jiangxi.

Li Daoxuan then turned his attention back to Li Da, first sent him a silver ball as a reward, and then said: "Your spring has been studied very well, and you can continue to solve the next problem." While researching the new muskets, don't forget to bring a few apprentices and teach them how to make the muskets you already know, our gunpowder is already available, it's time to make a batch of transitional muskets. ”

Li Da hurriedly responded to the order and returned to the craftsman with joy.

At this moment, the voice of people sounded on the official road outside, and Li Daoxuan turned his head and saw at a glance the county commander Liang Shixian and the inspector Fang Supreme, and the two were followed by a large number of officials and soldiers.

The government is visiting again.
