"Gunpowder?"

Fang Yiai was confused and said: "Is it the medicine that started the fire?"

The name is novel.

Even if it catches fire, it is still medicine after all, how can it become an important weapon of the country and related to the survival of the Tang Dynasty? ”

The gunpowder of this era was known only to a few Taoist priests, and it was not the gunpowder that later generations understood.

For example, top Taoist priests like Sun Simiao, they know how to make gunpowder.

However, the ratio is very unscientific, it can only help the fire to burn, it is neither violent nor explosive, and it cannot be used for military purposes at all.

Li Tai originally had no motivation to toss out the gunpowder in view of the invincible combat power of the Tang army.

However, the plan could not catch up with the changes, and he promised Li Shimin an oath to destroy Goguryeo in three years, and the invention of gunpowder became a top priority.

Goguryeo was different from nomadic peoples like the Turks, and it was a complete feudal power.

With a large population and a strong mobilization capacity, the conclusive data of later historians showed that the maximum mobilization force of Goguryeo could reach 600,000.

Its ethnic composition is dominated by the Buyeo people, the national character is aggressive and cruel, and it is good at defending the city, as evidenced by the large number of cities built on the border of Liaodong and the strong abnormality.

The Khitans, the ancestors of the Jurchens, are all Goguryeo servants at this time, and the Tang Dynasty's orders for these nationalities are not yet good for Goguryeo.

The barbarians only believe in iron and blood, and judging from the fact that Goguryeo commanded the Ya, Khitan and other tribes, its cavalry construction is also very good.

After a comprehensive analysis, Li Tai did not dare to despise Goguryeo at all, and regarded it as a fierce rival far beyond the Western Turks, Tiele, Xue Yantuo, and Tubo.

Without the assistance of the power of gunpowder, no matter how well Li Tai prepared for it, he would not have the full confidence to destroy Goguryeo in three years.

"That's not a bad thing you understand, but gunpowder doesn't just catch fire, it burns violently and even explodes!"

Li Tai smiled and talked to Fang Yi Ai Kop.

Fang Yiai was even more confused: "Explosion? ”

"Oh, it's just a sudden fire in an instant, and then it reaches ...... Thunder and lightning effect! Li Tai continued to popularize science.

"Thunder and lightning?

That's not scaring people to death, no, it's really going to kill people! Fang Yiai began to regret it after being shocked.

Li Tai said with a stumbling face: "Yes, if you are not careful, not only will you die, but you will also die miserably."

You know how the five horses are divided, right?

The effect is similar to that one, but the corpse of the five horses will only become five pieces, and after the gunpowder explodes, the person will explode into seventeen or eighteen pieces or even a pile of meat sauce.

There are no corpses, bones and ashes, which is the power of gunpowder.

Is it enjoyable, but not exciting? ”

Fang Yiai ran away: "I'm not going to do it, you better go to Ling Wu!" ”

"Hey...... A gentleman is hard to chase after a horse, you also know that I am now the king of Qin, and the king of Qin means the king of virtue to convince people.

You have broken the promise of a gentleman, which is very immoral, and I will be very unhappy.

I'm not happy...... Consequences, you know......"

Li Tai squinted his eyes and grabbed Fang Yiai with one hand.

Fang Yiai couldn't break free, and wanted to cry without tears: "Fourth brother, you liar!"

You obviously said that your eyes are sincere in addition to being simple, and you still put me in a hole of death! ”

Li Tai opened his eyes and said suspiciously: "Yes, I tell you simply and sincerely, I want to give you a divine object."

Gunpowder is so powerful, isn't it a divine object? ”

Fang Yiai was about to cry: "I'm not talking about this, what ......?"

"Rest assured, as long as you are careful, you will not travel to the pool.

Even if there is a business trip, I will play my father and posthumously bury you as the prince of the country.

Then carry it into the Lingyan Pavilion, so that future generations will remember your immortal feats. ”

Li Taiwen comforted, Fang Yiai really cried this time, Li Taiyu looked at me with a look of confidence that you are doing things, and then shouted: "Take a pen and paper!" ”

……

After half a cup of tea, Li Tai wrote down the composition and proportion of gunpowder, and wrote in detail the method of extracting saltpeter, as well as the method of use and precautions.

The ratio of black powder is very simple, and anyone who has studied high school will know it in later generations.

Li Tai solemnly handed the secret recipe to Fang Yiai with both hands, and said: "This matter must find a secret place to study, and in terms of manpower, we must use absolutely trustworthy family children!"

I said ugly things in front, this thing is related to the fortune of the Tang Dynasty, if you do this well, I will guarantee you a county prince!

If the news leaks, especially if the alien race gets the secret recipe for gunpowder, it is light to kill your head, and your family will wait for the end to be finished.

Remember!

Remember!! ”

Fang Yiai doesn't cry anymore, he is the second son of the Fang family without a title, and he is destined to only eat and wait for death to live a free life.

Now that Li Tai promises the future of his county father, his mother, even if his head is tied to the waistband of his trousers, he must give his mother a fight!

Gao Yang is so domineering, and his inability to attack the lord is one of the major factors.

He bowed to Li Tai, carefully took the secret recipe and hid it closely, and shouted in a low voice with a red face: "Fourth brother, don't worry!

This thing is here, my Fang Jun is here, this thing is lost, fourth brother, you can take off my head as a night pot!"

"I can't use your crooked melon and cracked jujube night pot, you work hard, don't mess up, it's better than anything else.

Remember, I'm just giving you a preliminary recipe that burns violently and explodes when used in large amounts, but the effect is not ideal.

You have to put more thought into encouraging the craftsman to think about improving and increasing the power.

Don't look down on craftsmen, but if you improve the power of gunpowder, I will not hesitate to reward you, and it is not a problem to increase the number of officials and knights! “

Li Tai has no doubt about employing people, since he decided to hand over the gunpowder to Fang Yiai, he will give him the most generous policy.

"Hey, I don't have two handfuls of rice in my hand these days, and I can't even coax chickens, so I'm relieved to have the words of the fourth brother.

As long as someone can improve the power of gunpowder, I will always offer him as an ancestor, right? ”

Although Fang Yiai is iron, he is not pedantic, he can go all out in the things he recognizes, and his mouth is strict enough, so he is the best candidate for studying gunpowder.

"Go ahead, I'll wait for your good news." Li Tai breathed a long sigh of relief, and finally implemented a major event.

…………

Yan Wan saw that Fang Yi's love was gone, and she came over curiously and asked, "You are bullying other people's beloved again, can we change someone to toss?"

It's been a few times, and the bereavement has sold you and helped you count the money, virtue! ”

Li Tai laughed and hugged Yan Wan and said, "Okay, it's okay to toss you, right?" ”

After the crossing, the husband and wife had never been so intimate, and Yan Wan was so ashamed that she couldn't do it.

After exclaiming, she quickly covered her mouth, and she was more shy and timid than Hua Jiao: "Death, this daylight is going to die?" ”

When you close the door and close your eyes, it will be dark, and Madame likes this tone, and her husband is willing to try it.

Let's go! ”

Although Yan Wan is already a wife, she is now in her twentieth decade, with both the demeanor of a young woman and the delicate beauty of everyone's ladies.

Li Tai's heart knot is gone, and the blood and qi have just been vegetarian for too long, how can he stand this.

He hugged Princess Yan Wan horizontally and walked to the bedroom as if nothing was there......

"Daddy, Uncle Nine said that there is no curfew in Chang'an today, and I want to go to the street to see the lanterns!"

Li Xin's voice suddenly sounded behind him, and Li Tai almost flashed his waist.

This unlucky child, Li Tai roared with a dark face: "Li Zhi!! ”

……

In Lu Guogong's Mansion, Cheng Biting Jin salivated and called his daughter Cheng Hanya out of the boudoir.

The old man smiled so much that he couldn't see his eyebrows and said: "Baby girl, you stay in the house all day long to read and practice martial arts, people are going to be stupid, this can't be done!" ”

Cheng Hanya slowly walked up to Cheng Yanjin and said lightly: "Father, what are you thinking?" ”

Lao Cheng sneered and said, "That's right, is Daddy that kind of person?" ”

"You're this kind of person, but my mother told me all your bad ideas!"

Although Cheng Hanya is shy of flowers, she has completely inherited her mother's excellent genes, but she has won the true inheritance of Lao Cheng.

She is about seven feet one meter seven or five meters tall, and at this time she looked at Cheng Yanjin with a cold face, and the old man who has never been afraid of heaven and earth actually made her daughter feel weak.

"Don't listen to your mother's nonsense, tonight, let's watch the lantern tour in Chang'an, there are only two opportunities a year, and there will be no store in this village after this village."

"Don't go, I want to read the book."

"Really?

'Look northwest, shoot the wolf, and the bow will be like a full moon!' ’

Don't you want to hear him complete? ”

Cheng Hanya was silent for a moment......
