Li Shimin's will: Li Zhi, the throne belongs to your brother

"I have the Feilei army, if there is God's help, from today onwards, the city wall will not be able to shelter, and the bandit army will have nowhere to hide.

The Feilei army must be victorious in every battle and invincible. "

Thinking of this, his eyes were sharp and his aura was breathtaking.

"Wherever the sun and moon shine is the territory of the Tang Dynasty, all who can breathe out will kneel and submit to me, and I will be the Son of Heaven."

Between the words, there is a heavy force that makes people want to bend their knees involuntarily.

Listening to the surging heartbeat, the Imperial Forest Army shouted with great excitement, their blood was surging.

"Your Majesty! The Tang Dynasty is mighty!!"

"Your Majesty! The Tang Dynasty is mighty!!"

Chapter 96

Compared with trebuchets and crossbows, Feilei Cannon is absolutely overwhelming.

It's no wonder that Li Shimin wants to form the Feilei Army. Who wouldn't want to have such a good weapon?

Amidst the cheers of the crowd, the iron barrel lasted less than ten rounds before it was blown up into the air, and when it hit the ground, it was shattered into pieces. Even after a day of searching with magnets, all the pieces were not found.

Li Shimin looked at the large bag of fragments brought, with a pained expression on his face.

Powerful, simple, easy to operate, and countless advantages, but the lifespan is less than ten rounds! !

This means that if you don't bring enough iron buckets, you may not be able to attack a few cities, and they will eventually turn into broken iron sheets.

This is very uncomfortable, it is impossible to fight halfway, and then let the craftsmen recast the tin barrel!

This is obviously impossible, and this limitation is simply too great.

And the very painful point is that this thing will blow up for you directly when it reaches the end of its service life.

There is no sign, and it will explode 100% of the time. If you don't do it well, you will hurt your own people. There is a feeling of hurting the enemy a thousand and hurting yourself a hundred.

This is very uncomfortable. Maybe after a battle, the enemy army will surrender directly with heavy casualties, while our army's casualties are due to the explosion of artillery shells.

"Huang Er, if the iron bucket is thickened, can it last longer?"

Li Tai saw Li Shimin's painful expression and knew what he wanted to say.

"Of course, this is just one type of cannon. There are countless cannons with longer life, stronger power and longer range."

Li Shimin suddenly asked excitedly: "Is this true?"

Looking at the excited Li Shimin, Li Tai explained with a smile: "Of course, there are not only flying thunder cannons, but more research and continuous experiments are needed to develop them."

Hearing Li Tai's words, Li Shimin immediately praised him, green light flashed in his eyes, like a weasel seeing a chicken.

He waved his hand and said very boldly.

"Don't you just want people?

Isn't it research?

I have plenty of people, just mention as many people as I want! !

As for research?

[-] catties of iron and countless gunpowder, even if they are used for research, they must be clearly studied for me. "

"This person needs to understand physics. As for [-] catties of iron... it's probably not enough." Li Tai looked at Li Shimin speechlessly, and poured a basin of cold water.

"Physics..." Li Shimin's face suddenly collapsed: "I'm afraid there are not many people in this world who know physics."

"So, isn't Erchen setting up a physics school?" Li Tai said with a sigh.

Li Shimin waved his hand and asked with a reproachful face.

"It turns out that Huang'er established the School of Physics to study this!

If only I knew that the emperor was studying this thing!Not to mention just ten people, that's 1, I'll give you all of them! "

Li Tai was very speechless, he originally wanted to directly study the steam engine, who knew you, Li Er, wanted to prove the power physically, so he hurriedly got all the thunder cannons.

Hearing that Li Shimin put so much effort into it, Li Tai frowned and asked: "... Are you serious?"

Li Shimin's tone paused, but then he said firmly: "Really."

Li Tai was taken aback by being willing to make such a big investment, and was just about to say something.

Unexpectedly, Li Shimin changed the subject and said: "However, this physics is too dangerous. It must be built near the blast furnace and must be under my supervision."

In the last second, Li Tai was still surprised by Li Er's generosity. Unexpectedly, in the next second, Li Er proposed that he also supervise the School of Physics.

Li Shimin wants to supervise the School of Physics?This change caught Li Tai unexpectedly.

It should be a good thing to invest too much, but it's just supervision... You don't need to think about it, Li Shimin must be using the School of Physics to study cannons in the name of supervision.

This has both advantages and disadvantages. The advantage is that the cannon can be researched soon, and the disadvantage is that his own steam engine may never see the light of day.

And even if it is researched, the output must be frighteningly low.

Because mining, smelting, casting and other technologies have not improved, the popularization and development of cannons are firmly restricted. Casting cannons requires all-round technological progress.

"Could it be that the emperor doesn't want to?" Seeing Li Tai pondering for a long time, Li Shimin asked a little puzzled.

"Father and emperor's thoughts are clear, but the casting of cannons has to be done slowly."

"The priority of the emperor's score, what else can be more important than the cannon?" Li Shimin persuaded earnestly.

Seeing Li Shimin's eager look, Li Tai could only helplessly explain.

"Father, don't worry, this cannon is as light as a thousand catties, and as heavy as ten thousand catties. If it is mined, smelted, and casted manually, it will cost a lot, and we don't know how long it will take.

Everything has to be done step by step, step by step. "

"This~"

Hearing Li Tai's explanation, Li Shimin was taken aback.

A tin bucket only weighs forty to fifty catties, and I have [-] catties of iron, so it should be enough.

But this [-]-jin cannon was really shocking. Doesn't this mean that my [-]-jin iron is nothing...

Looking at it this way, I instantly became poor...

Thinking of this, Li Shimin became silent. Looking at it this way, there are indeed too many places to develop, especially in mining and smelting.

He thought for a long time, then turned to Li Tai and asked, "What do you think, the emperor?"

"Uh." Li Tai pondered for a while, and kept complaining in his heart... what can I do.

"My son thinks that the physics of casting cannons, the School of Mathematics is used for calculations, the School of Chemistry studies gunpowder, and the three schools work together to solve the problem of casting cannons."

"Study by the Third Academy?" Hearing Li Tai's answer, Li Shimin was startled.

The research of the three academies undoubtedly attaches great importance to it, and success is only a matter of time.

But at the same time, it also means more investment in the follow-up, including money, food, and talents. This is not a problem, and you can still stick to it.

Most importantly, it means who should this institution belong to?

Does it belong to Li Tai, or does it belong to yourself?

Explosives, thunder cannons, and science have shown unprecedented horror and ferocity, and must be treated with caution.

"The three courtyards, how does the emperor think they should be arranged?"

Looking at Li Shimin's expression and questioning, Li Tai could see through Li Shimin's desire to occupy the three courtyards at a glance.

This is not acceptable, if Li Shimin takes it away, he will have to let this group of people study cannons every day.

"I feel that the three courts should be in charge of the court." Li Tai looked at Li Shimin without fear, not giving in at all in this respect.

Their eyes met, and both of them wanted to make the other back down.

In the end, the Imperial Forest Army interrupted the two people's staring, held a letter and a jar of salt in both hands and said: "His Royal Highness, a letter from the Li family in Longxi!!"

"Longxi?" Li Shimin took it and thought about it for a few seconds before remembering about drying the salt.

He opened the letter, glanced over it hastily, his face gradually became pleasantly surprised, and his eyes began to smile.

"The sun-dried salt method was successful, but it was delayed by the snow for a while, and then the news came, and the emperor made another great contribution!"

Even though he had known for a long time that the salt drying method could be successful, Li Tai couldn't help being delighted.

"The one in this jar is dried from the Longxi salt field, open it quickly and see how the salt is of good quality!"

"Yes!" The Imperial Forest Army opened the jar.

What was displayed in front of everyone was a lump of salt, which looked more like frozen snow instead of the fine grained salt familiar from previous lives.

This is because there is no anti-caking agent added to the salt at this time, and there are many commonly used anti-caking agents, such as potassium ferrocyanide, sodium ferrocyanide and so on.

If no anti-caking agent is added, it will condense into a block, which looks like a solidified and frozen snow block, so it is also called snow salt.

"It's the best snow salt!!"

Li Shimin was overjoyed, crushed it with his hands, put a small piece into his mouth, frowned, savored it carefully, and finally swallowed it.

"Pure, without a trace of bitterness, it is definitely the best snow salt."

"With this salt field, the Li Tang family can last for thousands of years, and the name of the emperor will be passed down through the ages."

While speaking, Li Shimin looked at Li Tai appreciatively.

"My son, thank you for your praise." Li Tai saluted quickly.

Salt is essential to man.It can be traced back to the earliest battle between Yandi, Huangdi, and Chiyou. Some people speculate that it was fought for Yanchi in Yuncheng, Shaanxi.

Salt is the real need. It is not uncommon to start a war for a mouthful of salt.

"There's no need to be polite." Li Shimin waved his hand, and his attitude softened.

"I don't know much about science, but the sun-dried salt method is a major event that benefits the country and the people.

The emperor's son is still in charge of the third hospital, and I will find a way to deal with the money and food matters! !

It's just about the cannon, the emperor can't slack off.

Cannons are the backbone of a country, and only those with cannons can speak confidently. "

"I understand!" Li Tai was stunned for a moment, but he didn't expect Li Shimin to retreat because of the salt.

Chapter 97

"There is currently no fighting at the border.

But I will still form an artillery army, and equip some flying thunder cannons first.

After the emperor researched the cannon, he equipped the cannon. "

Li Shimin hereby urged: "The Third Institute of Mathematics, Physics and Chemistry must cast the cannon as soon as possible. Don't worry about money and food."

"Yes, my son will go down the mountain to make arrangements and transfer Li Chunfeng here." Li Tai saluted quickly.

The appearance of Feilei Pao conquered Li Shimin, and even Li Shimin wanted to take all the three courtyards as his own.

Thinking of this, Li Tai praised his courage. Fortunately, the Third Academy was finally under his control.

Now it's time to think about how to allocate.

Li Tai thought for a long time, and felt that the military and people's livelihood should be separated.

"It's getting late and the snow hasn't melted yet. It's not safe to walk at night. Let's go down the mountain after the snow melts!"

Li Shimin glanced outside and warned.

"I obey." Li Tai agreed.

After leaving Li Shimin's place, Li Taiyou came to the place where Yang Siqi forged iron.

I saw ten craftsmen working in full swing, some were burning iron, some were cutting gears...

"Grassmen pay homage to Your Highness." Yang Siqi walked in front of Li Tai, sweating profusely.

"How's the progress?" Li Tai looked at Yang Siqi and asked.

"Your Highness, don't worry, it only takes three days to process the industrial master machine." Yang Siqi said with assurance.

"Well, three days." Li Tai nodded, ten people will process for three days, which should be enough time.
