"In the former Sui Dynasty, there was a loose horseman Huang Gon in eight wooden boats, put seventy-two wooden people, put them on the winding water, the boat around the winding water slowly, the wooden boat has a machine man in the bow of the boat, paddling in the middle of the boat, some holding wine glasses, some holding wine bowls.

Whenever the boat came to anchor at the bottom of the porch, the man handed the glass to the man on the shore, and when the man had finished drinking and returned the glass, he quickly caught it, turned to his companion who was holding the bowl, and asked for a wooden spoon to fill the glass, and then went down to another porch, and continued to pass it."

Yang Wulian said this, his face was full of reverence, admiration and nostalgia.

Li Xuan nodded and echoed: "The kid is fortunate to have read "The Legacy of the Great Cause", uploaded, there are seventy-two potentials, all carved wood. Or by boat, or by mountain, or by Pingzhou, or by Panshi, or by palace. The wooden figures were two feet long, and they were dressed in kilo and gold, and they were miscellaneous birds, beasts, fish, and birds, all of which moved like life, and walked with the winding water."

"It's a pity that in the midst of the war, the Huang family was destroyed, and it is difficult to get a glimpse of the past prosperity." Yang Wulian shook his head with emotion.

"When Emperor Yang was in power, he only indulged in the art of the mechanism, and did not try to fight in the world, otherwise, if there was no such loss in the three eastward expeditions to Liaodong, there would be no life in the troubled times at the end of the Sui Dynasty." Li Xuan's face was very flat.

When Yang Guang was alive, he thought that he was a man under heaven, and he was reckless in military force, and even the world was in chaos, and finally died and the country was destroyed.

"Yes, although the art of the mechanism is ingenious, the foundation of the world is still in the people's power, but if you can save the people's power, you can also stabilize the foundation of the world." Yang Wulian realized the omission in his words and immediately remedied it.

"Indeed." Li Xuan nodded, and then changed the topic: "I came here today to ask Yang Weng about gunpowder."

"You're not the first to come to me." Yang Wulian shook his head with a smile, and said apologetically: "You don't know, gunpowder is not good at this official, nor is it good at the craftsmen in the prison, if it weren't for the king of Nanchang, this official would probably have to send someone to take you to the medicine workshop to test the power of the gunpowder stored in the prison, but the king of Nanchang is here, and the official will speak bluntly."

"Yang Weng, please speak." Li Xuan paused for a moment, and then said, "Yang Weng can call the kid Twenty-Seven Lang, and you don't need to see the outside like the King of Nanchang and the King of Nanchang."

"Good!" Yang Wulian instantly smiled, nodded, and his face gradually became serious: "It was the third year of the general chapter, that is, five years ago, there was a skilled craftsman in the prison who had studied the art of gunpowder, but one day, the workshop where he worked suddenly exploded, and the entire workshop was directly blown up, killing seven workers and two supervisors, and after that, he was dismissed from his post and sent out of Kyoto, never to return."

"Why is that?" He couldn't help but cry out in a lost voice.

The prison will be involved in all matters of armament, and there are not a few people who die every year. c

It would be a bit too much to dismiss a person from his post and send him out of Kyoto for the sake of an accident that would never return.

"It's not here." Li Xuan waved his hand, frowned and thought: "If what the kid remembers correctly, in May of the third year of the general chapter, a big star fell in the southwest, the sound was like thunder, and the wild pheasants were all gone, and the government and the opposition were unknown. In June of the third year of the general chapter, the Dafeichuan army was defeated, and the skillful craftsman was afraid that he was unlucky and was impeached by the imperial history."

It's not so much that he was impeached by the imperial history, but that the emperor is in a bad mood.

The craftsman touched the emperor's mold at that time, and was naturally reprimanded out of Beijing.

As for the last person who will never return, it is Wang Bo.

After Li Xuan finished speaking, Yang Wulian nodded, and said: "Nowadays, the development of gunpowder in the prison is all based on the process left by that skilled craftsman, so there is some progress, but it has no great effect, far worse than the explosion of Tianjin Bridge that day."

After a pause, Yang Wulian said with a solemn face: "Although this official does not say that the incident was not done by that person, there are countless skilled craftsmen in the world, and the people who are in the prison and even the Ministry of Works are far from all, so it is not necessarily the person who did it."

He Yiqiu glanced at Li Xuan, but Li Xuan did not speak.

Although Yang Wulian said that, everyone understands that seventy percent of the world's skilled craftsmen are in the Ministry of Industry and will serve as supervisors, and the rest are either in wealthy families or in Taoist Buddhist sects, and only a few are in the countryside.

The way of craftsmanship is extremely expensive, if there is no clan family, or even one

The support of the power of the country is really difficult to achieve.

And if the things developed by the great craftsmen cannot be used in a country, they are tantamount to private waste and have no value.

"In any case, please also ask Yang Weng to tell that person's name and place of origin, so that Brother He can explain." Li Xuan's face was solemn, and then he asked curiously, "Before this, many yamen must have come to hear the news, Yang Weng won't not say any of them, right?"

Li Xuanhe wanted to come this time, just to find out how the gunpowder technique ended up in the Tianyin Sect.

In the Tianyin Sect, are there any other similar techniques?

The main altar of the Tianyin Sect is in the mountains around Muzhou and Wuzhou, Li Xuan went to Wuzhou this time, it is indispensable to explore it, if he can find it in advance, prepare in advance, his actions will be much smoother.

"Alas!" Yang Wulian waved his hand, looked at Li Xuan and He Yiqiu, shook his head, and said softly, "Actually, even if the official doesn't say it, the other people in the prison will say it."

Shaking his head, Yang Wu became upright, pressed his right hand on the table, and the next moment, the puppet quietly came out again, but this time in the wooden tray in his hand was no longer a tea soup, but a secret file.

When Li Xuan picked up the secret file to read, Yang Wulian looked at He Yiqiu and introduced: "At this time, the surname is Du Mingchun, a person from Luoyang, and his family is also rich, so he supports him to do such research."

Gunpowder research has always been dangerous, and if you don't pay attention to it, you will be injured in human life, and there will be countless losses and property.

Li Xuan nodded, and while listening, he carefully read the secret file.

Du Chun's research on gunpowder has surpassed that of almost the vast majority of people at that time.

In the secret file, he even made it clear that the power of gunpowder was focused on honey.

Honey, that's right, honey.

The *** in Li Xuan's hand: sulfur, realgar saltpeter, and honey burning......

The flames burn and burn the hands and burn the houses.

Of course, honey is honey, and honey can be turned into charcoal after heating and burning, plus sulfur and saltpeter, one sulfur, two nitrate and three charcoal, which is black powder.

Li Xuan suddenly felt a headache.

Although the focus of gunpowder research today is on honey, once it is discovered that it is because of charcoal, then the birth of black powder will completely disrupt the order of the whole world.

Now it depends on whether anyone can help Du Chun understand this, sometimes, one step is the difference between heaven and earth.

"Yang Weng, I don't know where Du Chun is now, can I find him?" Li Xuan stood up and solemnly bowed to Yang Wulian.

Yang Wulian shook his head, frowned and said: "The old man only knows that after he left the Divine Capital, he went to Songshan to cultivate, and later it was rumored that he left Songshan and went to the world to play, as for where he is now, it is really difficult to find, not to mention, his home is in Luoyang, he has not returned home for several years!"

Du Chun is originally from Luoyang, the eastern capital, and his parents and wife are in Luoyang.

The edict is to depreciate Kyoto, and naturally it is Luoyang, the eastern capital, and Chang'an, the western capital.

There is no home to return to, which makes it impossible for some people to do something to his family.

"Come to think of it, someone else has already come to the Du Mansion, if you can get something, you will have a result at this moment." Li Xuan frowned slightly, and said thoughtfully: "If you want to find him, it is absolutely feasible to do it, after Brother He goes back, you might as well send a message to ask the prefectures and counties in various places, and the consumption of sulfur, realgar and saltpeter will definitely be obtained."

Honey is a mountain and wild thing, even if it is not through the government, it can be obtained in large quantities, but although sulfur, realgar and saltpeter can also be found in the wild, if you want to use it on a large scale for a long time, you must go through the state and county markets.

As long as you keep an eye on this direction, you can always gain something.

What's more, if Du Chun is really in collusion with the Tianyin Sect, then through this, the traces of the Tianyin Sect's rebellion against the party can also be found.

"What the prince said is even." He Yiqiu stood up and said to Yang Wulian: "Thank you Yang Weng, if this matter can be successful, the lower officials will ask His Majesty for an order to make meritorious contributions to Yang Weng."

"It doesn't matter if you're old." Yang Wulian waved his hand

, said, "It's just that the old man hopes that when the two of you find him in the future, they can try to save his life."

In any case, Du Chun was a craftsman, and if his research on gunpowder could surpass that of his predecessors, it would have a great effect on the whole world.

Li Xuan arched his hand seriously and said, "The lower official must be."
