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

The grenade can be developed by Li Chunfeng, as long as the detonator is produced.

You have to think of a good thing that is simple, practical, and can be equipped quickly.

Li Tai thought for a long time, and finally remembered the god-like weapon——Flying Thunder Cannon.

The Flying Thunder Cannon is a weapon often seen in film and television dramas.

The main body is an empty gasoline barrel. After filling it with propellant, put the explosive package bundled into a disc shape into it, and then ignite the propellant, and the ten kilogram explosive package can be launched to a distance of 150-200 meters.

The caliber of this weapon is astonishing, as thick as the barrel is, the caliber will be as big, and the huge explosive package will generate a strong explosion shock wave, and wherever it passes, people, horses, and bunkers will be blown away.

Enemies who are blown up often can't find wounds on their bodies, but they will bleed to death from seven holes. This is because the shock wave shattered the internal organs, so they are called heartless cannons.

Even in a war, only one shot was fired, and the enemy was so frightened that they surrendered directly.

The advantages are obvious, the production, manufacture, and operation are simple, and it has a wide killing range and a long range.

And it can not only project explosive packages, but also project technical grenades, project tens of kilograms of large stones, project oil, deal with tanks, armored vehicles, and defend official duties. It is simply not too good.

The disadvantage is that it takes a certain amount of time to dig a hole for the arrangement, and it is easy to send yourself away if you do not operate properly.It was also because it was easy to give away his willingness that Feileipao withdrew from the stage of history.

Based on the current technology and strength of the Tang Dynasty, making fire guns is actually not as good as making flying thunder guns.

Because the Flying Thunder Cannon only needs a gasoline barrel and a disc-shaped explosive bag, there is basically nothing else.

Even if it is broken, it can still be used to fill soil to build fortifications, and even to block bullets.

Simple, rough, and wild, this is simply a necessary artifact for time travel, and it can be equipped quickly and on a large scale.

Thinking of this, Li Tai was excited all over, and thundered: "Yes!! Bring paper and pen!"

"Use mine." Li Shimin was overjoyed when he saw this, and quickly handed over the quill he had prepared earlier.

"..." Li Tai took it, and looked at Li Shimin speechlessly. Li Er, you have already prepared your feelings?

In Li Shimin's expectant eyes, Li Tai drew two ellipses, then connected them with two straight lines, marked the thickness, diameter... and finally wrote the words Feilei Pao.

"Father is ready." Li Tai handed the painted Thunder Cannon to Li Shimin expectantly.

Li Shimin took it with both hands, looked at it for a long time, squinted his eyes and began to look at this thing.

After reading it for a long time, I feel a little confused, as if I can understand it myself, compared to the awkward pinyin, even simpler than Yanchi...

This thing is like... like... a very common thing.

Why does this shape look more and more like a wooden bucket for bathing?

Is this painting a wooden barrel made of iron? ? ?

What's the use?Performing a beauty trick?

Li Shimin looked at the paper, and saw Li Tai's expectant eyes from the corner of his eye, but couldn't understand it.

"The more I look at it, the more it looks like a wooden barrel made of iron... Is the emperor playing tricks on me?"

"Why would my son make fun of this kind of thing, this is a flying thunder cannon!" Li Tai gave Li Shimin a look of contempt, isn't this a joke.

"Then how do you use the Thunder Cannon?" Li Shimin asked with an inexplicable guilt.

Li Tai briefly explained: "Well, ignite the propellant, and the propellant will explode and push the explosive package to fly 150 meters away. After the explosive package is deployed, it can kill the enemy."

After hearing what Li Tai said, Li Shimin felt more doubts in his heart.

Doesn't the explosion of the propellant ignite the explosive package?

There is such a thin iron sheet that cannot withstand the explosion of the propellant! !

···

"Can this really work?" Li Shimin expressed doubts about the practicality of this thing.

Li Tai nodded and said in affirmation.

"According to physics, this is possible. You just need to try a few more times to determine the amount of explosives and propellant, as well as the size and thickness of the iron barrel, and you will be successful."

Seeing that Li Tai was so sure, although Li Shimin was skeptical, he decided to give it a try.

Anyway, explosives are not worth much, even if the iron barrel is blown up, it can still be collected and used.

"Since the emperor is so sure, then I will make ten Tietong and try it according to what the emperor said."

"Let's go, follow me to find a craftsman, I want to see for myself how powerful this is!!"

"Yes!" Li Tai quickly followed Li Shimin.

The two came to the place where the tinkling of irons kept ringing.

"Cao Min pays homage to His Majesty." Seeing Li Shimin and Li Tai, the blacksmith quickly put down his work.

"Excuse me, come here Zhang Yajiu, and the rest will continue to work." Li Shimin glanced at him and said.

"Cao Min has seen His Majesty, what orders does His Majesty have?" Zhang Yajiu saluted.

"Come and take a look at this drawing, how long will it take to build it?" Li Shimin handed over the drawing.

Zhang Yajiu took it with both hands, and looked down carefully.

At first glance, it looks like a wooden barrel, but the wooden barrel filled with water on the ground looks more and more like it from the corner of the eye.

"It only takes one or two hours to build it, but..."

"Just what?"

"It's just that this whole piece of iron sheet, if it is to be thick and uniform, it will probably take longer."

Li Shimin looked at Li Tai.

Now there is no rolling machine, and the thickness of the beating must be uniform, so it can only be smashed manually.It seems that there is no need for this.

Li Tai thought for a while and said: "It doesn't have to be the same thickness, as long as it is made of high-quality steel, the drum made of it will be fine."

After listening, Li Shimin turned to Zhang Yajiu and said, "Isn't it going to be a long time now?"

"Reporting to Your Majesty, it is true."

Chapter 95

Hearing that the time has been shortened a lot, Li Shimin frowned and urged: "Do it faster, I am in a hurry."

"Yes!" Zhang Yajiu hurriedly bowed and left.

When he got the order, he turned around and organized a few craftsmen, and started discussing making tin buckets together.

They dragged out several thin iron plates not far away, which looked as if they had been sawed off from the edges of the large iron blocks from the first furnace.

The area alone is enough, but this is pig iron, uneven and uneven in thickness, and it has to be spliced ​​into a whole piece.

After discussion, several people used molten iron as an adhesive, burned the edges red, and rested the uneven places.

In this way, a rectangular iron plate and a circular iron plate are obtained.

Finally, after more than an hour of complicated red-burning and forging to remove impurities, the iron plate became slightly more flexible.

Fix the shape, and then glue it with molten iron, and a brand new handmade iron bucket is ready.

Looking at the result, Zhang Yajiu reported to Li Shimin in sweat, "Your Majesty, the grass miner has been completed, please accept it."

"Okay!" Li Shimin stood up hastily: "Move the iron bucket in."

"Yes." Zhang Yajiu waved towards the door, and a craftsman outside the door moved the iron bucket in.

Li Shimin walked over curiously, knocked the air rail pass 'bang bang', compared his own body shape, and said cheerfully.

"The whole body is round and can hold two me."

And Li Tai looked at the air iron with hammer marks all over his body, full of memories, and the corners of his mouth could not help but tears of memories, this thing is usually used to smoke all kinds of meat.

"Father, are the gunpowder and tools ready?" Li Tai asked Li Shimin, wiping the saliva from the corner of his mouth.

"The millstone, gunpowder, and shovel... I've got them all ready." Li Shimin replied with a wave of his hand.

"It's good over there." Li Tai glanced at it and felt that the tools were almost ready, so he ordered: "Go to a hillside and do a little experiment."

"Okay." Li Shimin turned his head and looked at the Imperial Forest Army: "Let's go!"

A group of people walked on the snow with various tools, and they made a creaking sound when they stepped on them. They followed the trail and came to the mountain near the iron mine.

"How is this?" Li Shimin took a deep breath and asked while looking at the snowy scene.

Here is halfway up the mountain, there are no trees blocking it, the view is very wide, it is very convenient to calculate the distance, it is a good place.

"Over there!"

Li Tai thought for a while, and began to dictate the process of the experiment.

This is different from the last time, this thing is easy to die, and it is easy to send yourself away if you don't pay attention.

Especially when Li Shimin, the Erha, was by his side, Li Tai didn't dare to do it himself, so he had to leave it to other people to do it.

"First dig a hole the size of an iron bucket and try using the hole.

First, use a 200-jin grinding disc to test how much propellant can launch the grinding disc to [-] meters.

Second, wrap the millstone with sackcloth, and see how many layers of sackcloth are wrapped with explosives so that it will not be blasted.

At this time, we are using iron drums to see how many explosions Tietong can withstand.

···

Remember that the lead wire is very long, and it must run far away after being ignited. "

Li Tai exhorted carefully.

"Emperor, do you want to try again and again?" Li Shimin heard Li Tai say this, and was a little worried that he didn't seem to have enough explosives.

"Of course, how many propellants and explosives are required to go through experiments, too much or too little will lead to catastrophe." Li Taibai gave Li Shimin a glance.

For the first experiment, he didn't know the specific data, so he could only order them to taste one by one to get the data continuously.

"Okay, let's try slowly!" Li Shimin wrote down Li Tai's words and handed them to the Imperial Forest Army.

Then he led Li Tai to near the top of the mountain.

After learning the lesson from last time, he didn't dare to move around at will, but started to supervise the work from a distance.

The Royal Forest Army started to work in full swing, some started digging with shovels, some started making fuses, and some started to tie explosives with bamboo.

Soon, Li Shimin and Li Tai watched the green smoke rising from below, and everyone dispersed like birds.

I only heard a "boom", accompanied by thick green smoke, a millstone rolled continuously, drawing an arc in the air, and finally landed in the snow-covered field 30 meters away with a "boom". .

"Okay!" Li Shimin watched and applauded loudly, and seemed to want to rush down to try it for himself.

"Father, it's only 30 meters, and it didn't work." Li Tai hurriedly stopped Li Shimin, who was as excited as Erha.

Visually measuring the distance, there are fewer launchers, 30 meters, and the distance from 150 meters is far away.

So in the next two hours, countless pits were collapsed, more than 20 stone millstones were damaged, and countless pits were left in the snow ahead, and the correct data was obtained.

For the last time, an iron bucket was used this time. Under the expectant eyes of everyone, the gunpowder was ignited, and everyone ran away skillfully.

With a bang, the explosive package rolled in the air with green smoke, and fell on the ground 150 meters away in an elegant arc.

In an instant, there was a louder explosion sound, and the earth was blown up to a height of ten meters, and the strong shock wave swept everything around.

Afterwards, a wisp of green smoke rose slowly, and another shocking giant pit appeared on the ground, which was already the nth pit.

The crowd, who were all used to it, suddenly burst into cheers.

"Congratulations, Your Majesty, Congratulations to Your Majesty, the Thunder Cannon has succeeded!"

"Emperor, the Thunder Cannon succeeded!!"

"Finally successful!!"

Li Shimin cheered happily, rushing down the mountain like a wild horse that has run free.

He seemed to be able to see the flying thunder cannons falling on the enemy's position, and the enemy's troops and city walls would be destroyed.

"What a flying thunder cannon!!" Li Shimin caressed the empty iron bucket with residual warmth, his eyes were affectionate and excited.

Even though he already knew the result, Li Tai couldn't help cheering with everyone.

"Thunder shakes the world, the dragon and the snake sting, and threatens the universe and moves the world."

Li Shimin glanced at the surrounding scene, all were devastated, and suddenly his heart was agitated, his pride burst out, his voice was high, and he said with contempt.
