Li Zhi, don't be a coward

Holding the small iron box in his hand, Li Qinzai was more cautious than ever.

This thing is a big killer, and it can explode without ignition. When Li Qinzai invented gunpowder and made a big firecracker, at least he had to pull out the fuse and manually ignite it to explode.

This time it was an upgraded version, if it accidentally collided with it, it would... With a bang, a mushroom cloud rose from the scene, and Li Qinzai and the people with a radius of about ten feet all escaped from the spot and became transparent friends in the spirit world.

Seeing Li Qinzai's solemn expression, Li Sujie and others did not dare to make trouble anymore and followed him from a distance.

Li Qinzai walked extremely carefully, pausing every time he took a step, making sure that his footing was still stable, before taking the second step.

It is impossible to blow up the school, the little bastards don't like reading, what's wrong with the school?

According to normal logic, of course it is reasonable to blow up the little bastards.

Go west after leaving the other courtyard, there is an open space, the terrain is relatively flat and wide.

Under the escort of the trilogy, Li Qinzai came to this open space, and then ordered Liu Asi to find a pleasing place to dig a hole.

Liu Asi didn't understand at all what Wu Shaolang had built, so he could only follow his orders meticulously, digging a hole when he said so.

A few parts were dug in twos and threes, and Li Qinzai held the small iron box, put it in the pit, and carefully covered it with soil, and the small iron box was buried in the soil like a small coffin for An Hanxiao Jiuquan.

After everything was arranged properly, Li Qinzai stood up and took a few steps back, heaving a sigh of relief.

Looking around, Li Qinzai said, "Where's Qiao'er? He likes to listen to the sound, so call him and let him listen to everything today."

Not far away, Li Sujie and other disciples were watching curiously. Qiao'er's weak body jumped out from the crowd, with his arms raised high, he said excitedly, "Father, here is the child!"

"Okay, just stand there and don't move any closer." Li Qinzai waved his hand, and then said to Liu Asi: "Go to the farmer and buy a sheep. It's suitable for both fat and thin."

Liu Asi said stupidly: "Do you want Wu Shaolang to eat lamb ribs or lamb legs? The villain will chop it up for you and bring it to you..."

Li Qinzai hummed, and with a shadowless foot, Liu Asi staggered.

"Live, I want to live! A live sheep that can walk, move, pant, and bleat, understand?"

"The villain will do it right away!" Liu Ah Si hurried away.

Not long after, Liu Ah Si brought a live sheep over.

The live sheep looked lazily, and while walking, they used their noses to push away the snow on the side of the road, trying to find a touch of green grass in the snow.

The sheep was brought to Li Qinzai. Li Qinzai knelt down and looked at it, then shook his head regretfully: "You look blessed, but unfortunately you don't have a lucky fate. My friend, your seal is black today, and you are destined to die. I'm afraid it will be difficult." cross..."

The little bastards behind gathered around one after another, looking at the sheep curiously, as if observing whether the sheep's seal really showed signs of turning black.

Li Qinzai couldn't help but burst into tears, "Is it easy for me, a mountain village teacher, to teach such a group of idiots?"I'm just silently carrying the burden for the big bosses in Chang'an City.

So, is the annual tuition fee of [-] per student expensive?It's not expensive at all, it's Li Qinzai's life money, and it's reasonable to increase the tuition next year.

Leading the sheep to the place where the pit was dug just now, Li Qinzai told the sheep to stay where it was, while he made a detour and walked far away from the pit before stopping. He grabbed a handful of wild vegetables and signaled to the sheep. .

"Take two steps, if you want to eat grass, take two steps!" Li Qinzai said expectantly.

In the winter, the grass in the field has almost disappeared, and the sheep must be very hungry. Seeing the green in Li Qinzai's hand, the sheep immediately walked towards him.

Everyone watched the sheep nervously, seeing it slowly walking towards the pit where the small iron box was buried, and seeing its hoofs almost stepping on the field...

Finally, Yang'er lived up to expectations, and finally stepped on the ground where the small iron box was buried.

boom!
The ground shook and the mountains shook, flesh and blood flew everywhere.

The blackened sheep didn't even have time to let out a scream before it was blown into the sky, and a rain of blood filled the sky, accompanied by the sheep's viscera and organs falling to the ground.

Bloodstains and various internal organs were scattered on the ground in a radius of several feet, and some blood spots were even splashed on the heads and bodies of the people watching from a distance.

Li Qinzai was still squatting in the distance, with an unspeakable smile on the corner of his mouth, and some blood spots were splashed on his head and body, but his expression at this moment was like the impermanence that opened the gate of hell.

The result of the experiment was already clear, the unlucky sheep died to pieces.

The onlookers were still sluggish, staring blankly at the piece of land where the gunpowder was almost exhausted. The loud noise just now was much more powerful than any firecracker Li Qinzai had ever done before, and it was simply not on the same level at all.

And on the land where the gunpowder smoke had cleared, there was an incomparably huge pit left, which was enough to prove how terrifying the power of that small iron box was.

It took a long time for Li Sujie to recover from the shock, and blurted out: "If the things created by the master are used in the battlefield..."

Li Xian was also surprised and said, "Just stepped on it, and it exploded..."

At this time, Qi Bizhen, a disciple of the general gate, also said solemnly: "If you bury it where the enemy army must pass, you don't need to light it, you don't need to lure the enemy, you don't need to design it. You only need a few small iron boxes like this, and the enemy army will be on the road to death. Too overbearing!"

Li Sujie nodded, and said solemnly: "This thing is much more domineering than the cannonballs you made before. In other words, it is the normal effect that gunpowder can produce. The firecrackers back then were just restrained deliberately."

The disciples were still in shock, but Li Qinzai walked over slowly, just in time to hear Li Sujie's words.

Li Qinzai couldn't help laughing: "That's right, it was deliberately restrained before. Whether it's power or weapons, too domineering will bring disasters, and they must be kept in cages, otherwise it will harm the peace of heaven."

Li Sujie looked at him with reverence in his eyes, bowed in awe, and said, "Since they should be kept in a cage, why did you release this sharp weapon out of the cage today?"

Li Qinzai looked in the direction of Chang'an and said in a low voice: "Because your father is about to start an epic battle, this war will determine the rise and fall of the dynasty, and also determine whether your father can sweep away the hatred of the emperors of the two dynasties. Son Lang's blood feud."

All the princes and the children of the powerful and powerful were present, and they understood the meaning of Li Qinzai's words as soon as they heard it.

Li Sujie was surprised and said: "Father wants to conquer Goguryeo again?"

Li Qinzai nodded.

Qi Bizhen saluted and said: "Dare to ask, sir, what is the name of this small iron box you made?"

Li Qinzai smiled: "It's called 'Landmine'. As the name suggests, it is a mine that is buried in the ground. It can hide the killing intent in the ground and damage the enemy's army without a trace. You only need to bury it on the road that the enemy must pass. , to the enemy army, it is a step-by-step killing opportunity, causing hundreds of casualties at every turn."

Li Sujie murmured: "Landmines, landmines... as expected, I dare to ask sir, is the principle of this thing related to Gewuxue?"

Li Qinzai smiled: "That's right, the gunpowder inside uses chemical principles, but the internal structure mechanism is based on the principles of mechanics and friction in Gewu. It is a product of physics and chemistry."

"I once said that the principles of all things in the world can be expressed in physical chemistry. As long as you learn it thoroughly and use it well, even ordinary people can cause thunder, destroy the world or benefit the common people."
