Datang Nongsheng

Chapter 647 The Secret That Can't Be Said
There was a long silence in the cabin, and after a long time, Li Yuhua said, "I really shouldn't let you participate in this matter, but even if you can't trust His Majesty's heart, can't you still trust yourself? If this Things can be applied to the battlefield. Our Tang Dynasty will no longer need to fill the battlefield with the lives of soldiers, and no foreigner can destroy the prosperity and stability of our Tang Dynasty. It will be of great merit to the country and the people. You can do this to eradicate Wang Hao. Why can't you do what you can for the common people in the world, even if you can give up your fame, wealth and status?"

Sun Xiangfu didn't know how to pick up what he said. Sometimes, it's not that you don't do it, and others will feel at ease. His merits and popularity basically don't need to die.

However, once involved in this matter, if the emperor is worried about him, he may not be the only one who died. In order not to leave a root of trouble, the entire Sun family may be wiped out.

Moreover, in Sun Xiangfu's view, appearance is very important. He grew up in a social environment where good looks are everything, and no face destroys everything. In addition, he has always been afraid of death, so he is absolutely It is impossible to personally participate in the actual research of gunpowder. After thinking for a long time, he finally said, "Actually, it's not that I don't want to help. It's just that I really don't understand this thing. You can tell me about it." The process of preparing it, but don’t tell me what it is made of and what ratio it is made of, I can help you analyze the cause of the explosion, and I really can’t do anything else.”

Gunpowder was invented by alchemists as early as the Spring and Autumn Period. At first, it was only used to light fire. It was not until the end of Tang Dynasty that it began to be used on the battlefield. At that time, it was still mainly used to light fire. God bless Emperor Zhaozong of Tang Dynasty In the first year, when Yang Xingmi's army besieged Yuzhang, they used a stone-throwing machine to ignite the hanging wire, then threw the gunpowder bag and burned down the city gate.

In the Northern Song Dynasty, the government established a gunpowder workshop, and gunpowder arrows, thunderbolt guns, etc. appeared, mainly based on combustion propulsion, and slightly explosive gunpowder weapons were produced, but their real lethality was not great, otherwise, the Northern Song Dynasty would not Will be defeated by Liao Jin one after another.

Now, due to Li Yuhua's research, the power of gunpowder has been greatly improved. Through Li Yuhua's narration, Sun Xiangfu learned that he ignited a bamboo tube of gunpowder when he was testing the combustion propulsion of the newly configured gunpowder, and then produced explode.

Judging from the amount of gunpowder in the bamboo tube and the resulting results, the gunpowder he prepared was not very powerful, because it almost exploded at a super close distance in his hand, and only broke two of his fingers. It didn't seriously damage his internal organs. This distance from the best proportioned black gunpowder should be a little bit short. However, if it is used on the battlefield during this period, it is indeed enough to crush the opponent.

Because, put the gunpowder of this energy into clay pots, add iron nails, ignite it, and throw it into the enemy's formation, which is enough to destroy the enemy's formation and make it chaotic. Wooden city gates, clay walls , It can basically be blown to pieces. With it in hand, the attack of Tang Jun in iron armor is almost irresistible in this world.

Then, Sun Xiangfu soon heard a loophole in Zhang Yuhua's explanation, that is, he didn't make a fuse, but directly ignited the gunpowder filled in the bamboo tube. It's no wonder that he didn't hurt himself!

Don't underestimate the process of gunpowder from burning in powder form, to being set up, ignited with a hanging wire, and then sealed, and ignited with a fuse wrapped in gunpowder. It has gone through hundreds of years. The research and improvement of a gunpowder craftsman finally took shape.

"You need to add a fuse to the gunpowder device you only made, that is, something that can burn slowly and then detonate it."

"Lead?" Zhang Yuhua thought about the idea proposed by Sun Xiangfu, and then his eyes began to light up.

His original research direction has always been how to make gunpowder more instantaneously flammable, so it produces impact, and uses it to push arrows to achieve the effect of long-range attacks. But later, the explosion of gunpowder made him notice that this thing exploded The power, and the lead wire is a good solution to it being too violent and easily injuring its own people.

"Yes, the lead wire is to wrap the gunpowder you have prepared in a thread made of soft paper, connect this thread with the gunpowder inside the bamboo tube or clay pot, ignite the lead wire, and put the bamboo tube Or when the clay pot is thrown, it just burns into the sealed bamboo tube or inside the pot, causing the whole thing to explode and kill the enemy.

Of course, if you use a bamboo tube, the lead wire does not need to be very accurate, but if you use a clay pot, if you can't accurately calculate the length of the lead wire, the lead wire will be burned after the pot falls to the ground, then it may be Appearance is just the effect of igniting the gunpowder exposed to the air to burn and start a fire. "

What Sun Xiangfu said was very simple and clear, and Li Yuhua could understand it as soon as he heard it. Then, he excitedly raised his hand with only three fingers left, and said to Sun Xiangfu, "You really can help me solve this problem." People, please allow me to thank you on behalf of all the people who have lived a prosperous and stable life for a long time because of the birth of this new weapon."

"No, don't do this with me. If you want to say thank you, the people should thank you. After all, this kind of explosive gunpowder was developed by you.

In addition, don't think that it can be applied to the military immediately after solving this problem. In fact, it is difficult for you to ensure its safe production before the configured industrial production line cannot meet the standards. When using it, preventive measures should not be taken If it is in place, it may cause disasters for our army, and once it is spread and abused, then we may not be heroes, but sinners. "

Gunpowder, at any time, is a dangerous product, especially when a group of people who don't understand its characteristics use it. When Sun Xiangfu said this, Li Yuhua's face suddenly became serious, and he was caught at close range. After the gunpowder was injured, it knew too well how powerful this thing would be if the amount was increased. This is why Li Shimin was very cautious and specially sent secret guards to take charge of the secrecy work. It seems that he lost his fingers and face. Value, it just made him take a big step forward in the field of gunpowder research, but in the field of application, he still has a long way to go.

After just one meal, Sun Xiangfu got off Li Yuhua's boat. Now, the paper mill can produce all kinds of paper and qualified leads according to his requirements. It should only be a matter of time. Sun Xiangfu said goodbye to him When the lead wire was made, how long it would take to burn a foot long, and how long it would take to burn a foot long, should be calculated with a relatively accurate time, the amount of gunpowder contained, and what kind of explosive force it would produce roughly. , The extent of the spread also needs to be calculated more accurately. If these data are not accurate, it is likely to hurt your own people in the application, and then there is the issue of confidentiality.

In fact, with Datang's current military strength, there is little need to manufacture gunpowder at all, but early research and progress will have the benefits of early research and progress. It can give the country an additional layer of military protection, so as not to be ahead of others sometimes. Instead, it would not be beautiful to let ourselves be overthrown by the things first invented by our ancestors.

Of course, it's not very good to have an extra secret in my heart, so when I go home for dinner, the atmosphere is very wrong.

"Don't my husband have anything to say to my concubine?"

"This matter! Your Majesty has a strict order, I must not mention it to anyone, including you, so ah! You better not ask."

"This is not what I said, the child's Uncle Dali has already told me about this before."

"Oh, so what else is there to say?"

"Your Majesty has no intention of letting you go back to Chang'an to work?"

"No, even if there is, I don't want to go back to do this thing. This thing is more dangerous. Even if I resist the order again, I won't do it."

Hearing this, Yu Xiu'er didn't show any disappointment, but instead said with a look of joy, "It's the best. Husband is here to cultivate the fields and educate the people, it's better than going to the court to be an official."

Hearing that, Sun Xiangfu looked at Yu Xiu'er in surprise. She didn't have such an attitude before. It seemed that she and the entire Yu family expected her to become the pillar of the country. Now, why did she change her temper?

"Xiu'er! Could it be that you also like the life in Jiuyuan County and don't want to go back to Chang'an? Or, do you think that if your husband continues to be here, the family will be more prosperous? So... "

Yu Xiu'er smiled and shook her head and said, "Not at all, my husband knows, who is the last person who can be a teacher for the world?"

Sun Xiangfu said inexplicably, "Teaching the world? Confucius?"

Yu Xiu'er nodded and said, "Exactly, and now, my husband, you are almost the teacher of the people in the world."

"This...Xiuer, do you want me to be a saint again?" Sun Xiangfu heard what Yu Xiuer was thinking and immediately understood what Yu Xiuer was thinking. For a moment, the high officials of the imperial court, what do they care about!

If Sun Xiangfu has an official position, then he should do it within the scope of his duties to educate the people.

Now, he does not have an official position, but devotes himself to educating the people, and he educates the people for free, which is even more rare.

"It's not that the concubine wants it, but the husband has been doing it himself. After getting married in Chang'an and Princess Linchuan, Deshou has returned to Shanyang. It is said that the dowry given to Princess Linchuan by the Empress and Concubine Wei is only gold. In terms of money and money, it is as high as 500 million guan, which is several times more than the betrothal gift spent when the prince married Shu Ya. Deshou and Princess Linchuan decided to donate all the money to the people in poor areas. Build schools where children can study for free.

Moreover, these schools will also add agricultural subjects. All students, if they have a good foundation in agronomy, can go to the agricultural college in Shanyang to learn more advanced agricultural techniques for free. Hello, after a hundred years, you may not be elected as a saint by the people. "

Hearing this, Sun Xiangfu was silent for a long time, and finally slapped his thigh and said, "I know why you care so much about the influence of our family during this time. Even when your own children are crying, you are afraid that others will know. It turns out that you are afraid that someone will My image is damaged, and I want to push me to the position of a saint, but this is really tiring."

"Being a bit tired, if I can exchange for the title of a saint, I think it's worth it for the descendants of my Sun family. By the way, my husband is not allowed to take the children to play on the street in the future, and be seen by others. ..."

Listening to Yu Xiuer's nagging, Sun Xiangfu was full of sadness, which made him more depressed than suddenly having a secret that he couldn't tell.
