At the same time, Zhong Gaoliang was rejoicing to regain his white body.
North, Qingjian County.
A scholar named Zhao Sheng was reading at night in the Oil Temple.
Zhao Sheng failed in many tests and was never able to gain fame or become an official. However, he was a good character. Whenever the villagers nearby asked him to write letters to the family, help read the official papers, etc., he would help.
When he has free time, he will tell some stories from the book to the nearby villagers, which is deeply loved by the people.
That night, while he was reading a book in the Petroleum Temple, a young monk slipped in and said eagerly: "Mr. Zhao, run!
Zhao Sheng: "?"
The young monk whispered: "The government has sent someone to fetch you. Some people are rumoring that Mr. lighting lamps in the lonely temple at night is like the Huang Chao described in the Chinese language who made a military book and rebelled..."
Zhao Sheng was shocked: "Why did you say this?"
The young monk: "It doesn't matter how you got here, run away quickly, the government officials are coming soon.
It turns out that the situation in Qingjian County is already very tight. There are people revolting and revolting in every county in Shaanxi. The government is nervous. As soon as it hears that someone is going to rebel, the government will immediately take action, regardless of Qinghong. Zaobai took the person back and beat him into a move.
Zhao Sheng gritted his teeth, "Damn it, I just want to study hard, take part in the imperial examination next time, be nominated for the gold list, and honor my ancestors. Why are you doing this to me?"
He quickly packed up his books and escaped through the back door of the Oil Temple.
Fleeing all the way to Xiejiagou, a large group of government officials chased him from behind.
Zhao Sheng was just a weak scholar with industrious limbs. He was about to be caught if he could outrun the government officials. Suddenly he heard thunderous shouts in the fields, and a large number of ordinary people came over with hoes, wooden sticks and other things to kill him. .
"Damn the government, don't do anything to Mr. Zhao!"
"Mr. Zhao is a good person, but you are indiscriminate and slandering good people."
"I rebelled today."
"Kill these government officials to death."
A large number of ordinary people rushed out, instantly turning the government officials into child fans.
It was early morning at the end of April in the first year of Chongzhen.
Li Da rushed out of the blacksmith shop, holding a small spring in his hand, looking up to the sky and laughing: "Hahahaha, I succeeded, I finally succeeded, the elasticity of this thing is finally restored, hahahaha, I succeeded. .
Li Daoxuan, who had just gotten up and was sitting by the box chewing glutinous rice balls, couldn't help but be attracted by Li Da and quickly looked over.
I saw Li Da running quickly downstairs, not daring to go up. He raised his head and shouted to the third floor: "Holy Lady, are you up? Look, look at this."
I saw Gao Yiye sticking his head out from the balcony.
Li Da immediately put the spring between his palms, pressed it hard towards the middle, and then released it, the spring popped open again.
"Look, I succeeded, hahaha, I succeeded."
Gao Yiye no longer has dark circles under her eyes. In recent days, Li Daoxuan has called her as little as possible so that she can spend more time painting during the day so that she can sleep well at night.
She watched Li Da finish his performance with a smile, 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, did you see it? I...I succeeded...I heated this thing red, and then quickly put it into cold water. It regained a little elasticity, Although it’s not as elastic as before, at least it won’t collapse when pressed.”
Li Daoxuan thought to himself: You discovered the "cooling method" accidentally, which is great.
However, his method was still very rough, and there were more detailed steps in the cooling method. Li Daoxuan had already checked it out, but he was not in a hurry to give it to him, wanting him to think more about it.
"Do you know why after it is heated and then quickly cooled in cold water, it can regain a certain elasticity?
"No... I don't know." Li Da shook his head.
Li Daoxuan sighed inwardly: Just like most of the ancient technologies of our dynasty, we only know what they are, but don’t know why. well!
You know that water will turn into gas when it boils, but you don’t know that when water is heated, the thermal energy of water molecules increases, causing the average kinetic energy of water molecules to increase... So even if you know that water turns into gas when it boils, Still don’t understand anything.
You know that rapid cooling of a spring will restore its elasticity after it is red-hot, but you don't know that the cooling method will make the atomic distance smaller and increase the internal stress, thereby restoring the elasticity of the spring.
You understand, but you don’t understand.
This is all due to the lack of basic science!
Li Daoxuan whispered: "Yiye, go and call Taoist Master Ma."
After a while, Ma Tianzheng came. He was different from ordinary villagers. As soon as he heard the call of Tianzun, his face immediately glowed red. When he arrived in front of the watchtower, he bowed to the highest Taoist prostrations: "Disciple Ma Tianzheng, here to obey your orders."
Li Daoxuan: "Li Da, put the spring in Taoist Ma's hand. In addition, go get a bag of cement and give it to Taoist Ma.
Li Da quickly followed the instructions.
Ma Tianzheng was holding a bag of cement and a spring. He glanced left and right, looking at the things in his hands with a blank look on his face: "I don't know what Tianzun ordered. Disciple...can't understand it."
"There is a glorious and arduous task for you." Li Daoxuan: "Take these two things and go to the Waxi Archway in Fengxin County, Jiangxi Province. There is a scribe named Song Yingxing there who failed the scientific examination many times. Doubt life. After you find him, put these two things on him
With your hands, show him the elasticity of the spring first, and then teach him how to use cement.
Ma Tianzheng said: "It's just a trip to Jiangxi. It's not too difficult for me, so I'll set off now.
Li Daoxuan: "Well, let's go! Be careful along the way."
Ma Tianzheng said: "This disciple will protect these two sacred objects with his own life."
Li Daoxuan shook his head: "Protect yourself. If you lose these two things, you can still come back to Gaojia Village to get them. If your life is lost, it will be gone."
Ma Tianzheng burst into tears with gratitude: "Tian Zun is kind, and this disciple's skin is not worth mentioning."
He quickly packed his luggage, tied his leggings, brought dry food, and solemnly hid a small bag of cement and springs. Then he left Gaojiacun and headed for Jiangxi.
Li Daoxuan then turned his attention back to Li Da. He first gave him a silver ball as a reward, and then said: "You have done a great job in researching this spring. You can continue to solve the next problem. In the research While you are preparing new muskets, don’t forget to bring a few apprentices and teach them how to make the firecrackers you already know how to do. We already have the gunpowder, so it’s time to make a batch of transitional firecrackers.”
Li Da quickly obeyed the order and returned to Jiangjing happily.
At this moment, voices rang out on the official road outside. Li Daoxuan turned his head and saw the county magistrate Liang Shixian and the inspector Fang Wushang. Behind them were a large number of government officials and soldiers.
The government came to visit again.
