"gunpowder?"

Fang Yiai was confused and said: "Is the medicine for the fire?"

This name is novel.

Even if it catches fire, it will be a medicine after all. How can it become a major weapon for the country and affect the survival of the Tang Dynasty?”

Only a few Taoist priests knew about the gunpowder of this era, and it was not the gunpowder understood by later generations.

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

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

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

However, the plan could not keep up with the changes. He made a vow to defeat Goguryeo in three years, and the invention of gunpowder became the top priority.

Goguryeo and nomadic peoples like the Turks are different, they are complete feudal powers.

With a large population and strong mobilization ability, the conclusive data studied by historians in later generations, Goguryeo's highest mobilization force can reach 600,000.

The ethnic component is mainly Fuyu people, the ethnic group is fighting and cruel, and he is good at defending the city and fighting. The large number of cities built on the Liaodong border are proof of which are extremely strong and sturdy.

The Khitans and the ancestors of the Jurchens, the Marines, were all servants of Goguryeo at this time. The Tang Dynasty's orders to these nations were not as good as those of Goguryeo.

The barbarians only believe in iron and blood. Judging from the fact that Goguryeo ordered the Marine, Khitan and other tribes, their cavalry was also well built.

After comprehensive analysis, Li Tai did not dare to underestimate Goguryeo at all, and regarded it as a strong enemy far surpassing the Western Turks, Tiele, Xueyantuo and Tubo.

Without the assists from gunpowder attack, even if Li Tai did his preparations well, he would not have the full confidence to destroy Goguryeo in three years.

"It's good that you understand this way, but gunpowder not only catches fire, but also burns violently or even explodes!"

Li Tai smiled and popularized science with Fang Yiai.

Fang Yiai was even more confused: "Explosion?"

"Oh, it just caught fire suddenly and then achieved...thunderous and lightning-like effect!" Li Tai continued to popularize science.

"Thunder and lightning?

That's not to scare someone to death, no, maybe it will really kill people!" Fang Yiai began to regret it after being shocked.

Li Tai looked so naive and said, "Yes, if you do it carefully, you will not only die, but also die miserably.

Do you know if the five horses are dismembered?

The effect is similar to that, but the five horses will only become five pieces of corpses. After the gunpowder explodes, the person will be fried into seventeen or eighteen or even a pile of meat sauce.

If you die without a complete corpse, your bones will be crushed and ashes will be raised, it means the power of gunpowder.

Not satisfied, isn't the thorn irritating?"

Fang Yiai ran away: "I'm not going to do it anymore, you'd better go find Lingwu!"

"Oh... a gentleman is as good as hell. You know that I am the King of Qin now. The King of Qin means a king who wins people with virtue.

If you violate the promise of a gentleman, it is very immoral and I will be very unhappy.

I'm not happy...you know the consequences..."

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

Fang Yiai couldn't break free and said in tears: "Fourth brother, you liar!

You clearly said that your eyes are nothing but simplicity and sincerity, but you still cheat me to death!"

Li Tai opened his eyes and said in confusion: "Yes, I will tell you simply and sincerely that I want to give you a magical object.

Can't gunpowder be considered a divine object with such power?"

Fang Yiai was almost crying: "I wasn't talking about this, so what..."

"Don't worry, as long as you are careful, you won't be on business trips.

Even if there is a mistake, I will report to my father to posthumously enthrone you as the Duke of the Scenic and Blessings.

Then carry it into Lingyan Pavilion so that future generations and descendants can remember your extraordinary achievements.”

Li Tai comforted her, Fang Yiai was really crying this time, Li Tai still looked at you as if I was relieved to do things, and then shouted: "Get paper and pen!"

...

After half a cup of tea, Li Tai wrote down the ingredients and proportions of gunpowder, and explained in detail the methods of extracting saltpeter, as well as the methods of using and precautions.

The ratio of black gunpowder is very simple, and anyone who has been to high school in later generations knows it.

Li Tai solemnly handed the secret recipe to Fang Yiai with both hands and said seriously: "This matter must be studied. In terms of manpower, we must use an absolutely trustworthy family to have children!

I am ugly in the beginning. This thing is related to the fate of the Tang Dynasty. If you do this, I will protect you as a county magistrate!

If the news is leaked, especially if the aliens get the secret recipe for gunpowder, it will be light to kill you, and your Fang family will be fine.

Remember!

Remember!!"

Fang Yiai stopped crying. He was the second son of the Fang family who had no title, and was destined to be able to live a life of life by just waiting for death.

Now Li Tai is the future of his county duke, even if his head is tied to his belt, he must fight for his mother!

Gao Yang is so domineering that his own inability to succeed is one of the major factors.

He had been worshipping Li Tai for the most week, and carefully took the secret recipe and hid it in his body. He blushed and shouted in a calm voice: "Don't worry, Fourth Brother!

This thing is here, my room is here, this thing is missing, Fourth brother, just take off my head as a chamber pot!"

"I can't use your crooked chamber pot. You should do your best. Don't mess up your job and do anything better than anything else.

Remember, what I give you is only a preliminary secret recipe, which can burn violently and explode even if it is used largely, but the effect is not ideal.

You should use more thoughts to encourage craftsmen to think about improvements and enhance their power.

Don’t look down on craftsmen. I will not hesitate to reward craftsmen who have improved the power of gunpowder. It is no problem to be promoted to a higher position!”

Li Tai was unquestionable in employing people. Since he decided to hand over the gunpowder to Fang Yiai, he would give him the most favorable policies.

"Hey, I don't have two handfuls of rice in my hand these days, and I can't even coax the chicken. With the words of the fourth brother, I feel relieved.

As long as someone can improve the power of gunpowder, I will always give it to my ancestors, right?"

Although Fang Yiai is strong, he is strong because he is not pedantic and can do his best to find out what he believes in and his mouth is strict enough. He is the only candidate to study gunpowder.

"Go, I'll wait for your good news." Li Tai sighed and finally implemented a major event.

…………

Yan Wan saw Fang Yiai leaving happily, and came over curiously and asked, "You bullied others again. Can we change our own efforts?

This has been a few times. I asked you to sell it and count your money. Is it a virtue!"

Li Tai laughed and hugged Yan Wan and said, "Okay, have you done it?"

After the time travel, the couple had never been so intimate, and Yan Wan was so embarrassed that she was so happy.

After exclaiming, he quickly covered his mouth. She was shy and timid and said, "Diet, are you going to die in broad daylight?"

"When you close the door and close your eyes, it's dark. The lady turned out to like this tone, and she was happy to try it out for her husband.

Let's get up!"

Although Yan Wan is already a wife, she is now in her twenties. She has the grace of a young woman and the beauty of a lady from a wealthy family. It is the most invisible flirting with a man.

Li Tai's heart is gone, and his blood and energy have just been vegetarian for too long, so how can he bear this?

He hugged Princess Yan Wan and walked towards the bedroom as if nothing had happened...

"Dad, Uncle Jiu said there is no curfew in Chang'an today, and I want to go out to see the lanterns!"

Li Xin's voice suddenly rang behind her back, and Li Tai almost flashed his waist.

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

...

In Duke Lu’s mansion, Cheng Yaojin called his daughter Cheng Hanya out of the boudoir with a saliva face.

The old man smiled so hard that he couldn't see his eyes and said, "Baby daughter, you are always in the mansion to read books and practice martial arts, and you will be stupid. This is not true!"

Cheng Hanya slowly walked to Cheng Yaojin and said lightly: "Father, what are you thinking about?"

Lao Cheng smiled and said, "Is Daddy the kind of person?"

"You are such a person, but my mother told me all your bad ideas!"

Although Cheng Hanya was so embarrassed that she had completely inherited her mother's excellent genes, she was very arrogant and had the old Cheng Zhenzhi.

She was about 7 feet, one meter, and seventy-five meters tall. At this moment, she looked at Cheng Yaojin with a cold face. The old man who had always been fearless actually made her daughter feel weak.

"Don't listen to your mother's nonsense. Let's go to Chang'an tonight. There are only two opportunities a year. After passing this village, there will be no store."

"If I don't go, I want to review the book."

"I really won't go?

‘Looking northwest, shooting the sky wolf, you can pull the carved bow like a full moon!’

Don't you want to hear him complete it?"

Cheng Hanya suddenly fell silent...
Chapter completed!
