The mine seems to be tall, but in fact, the internal structure is not complicated. Diaphragm

And the earliest place of origin of this thing is China. As early as the Southern Song Dynasty, the earliest mine in history appeared, which was called "earth-shaking thunder" at that time, buried in the ground and ignited and detonated with a fuse.

Later, in the Yongle period of the Ming Dynasty, there was a book called "Fire Dragon Artifact Formation" also mentioned mines, which people called "explosive cannons" or "self-inflicted cannons".

Later, during the War of Resistance Against Japanese Aggression, landmines were a must-use artifact for destroying the enemy by the anti-Japanese forces in various parts of our army.

In the famous movie "Mine Warfare", all kinds of strange landmines are the wisdom of our working people.

They used the simplest materials to create mines that frightened the pirates, and because they were afraid of the mines, they could only hide in the turret and did not even dare to go out.

The mines made by Li Qinzai are trigger-type mines, which explode when you step on them, and he has advanced the appearance of landmines by hundreds of years.

It is not difficult to make materials, let the blacksmith build several connecting devices, build a flint, once someone steps on it, the connecting device on the surface sinks, and the flint is rubbed under the action of gravity, and the gunpowder in the mine is detonated. Diaphragm

To be honest, the manufacturing process really frightened him, and he was reflecting on why he died several times.

However, thinking about the reality of the Tang Dynasty's imminent eastward expedition to Goguryeo, Li Qinzai gritted his teeth and created it.

The effect is obviously ideal, and when there are no errors in various parts and data, this thing really explodes as soon as you step on it.

"Physics, chemistry......" Li Sujie and the others still looked shocked, muttering in their mouths.

Li Qinzai sighed and said: "These studies of mine, I begged you to learn in class, but you didn't care, and they waited for holidays one by one, and now that my knowledge is applied to reality, you should understand what is going on." ”

"The former cannon battle, the hydraulic press, the three-eyed gun that the Tang Dynasty has been equipped with, and this mine, etc., are all made by the principles of physics and chemistry, and the Son of Heaven has said that my knowledge has the ability to destroy the world, and I am willing to teach it, but you love to ignore it."

Li Sujie said with shame on his face: "It's the disciple's mistake, but the disciple wants to tell Mr. that in the recent past, we have been in Princess Xuancheng's ...... Well, with the help, the disciple's grades have improved by leaps and bounds, and the gentleman said that he must pass before the year-end holiday, and the disciple asked himself if he could do it. "Ahh

The rest of the disciples echoed one after another, their faces full of confidence and faintly embarrassed.

Li Qinzai's eyes widened in surprise, and then he found Princess Xuancheng in the crowd.

Xuancheng hung his head and was silent, his pretty face slightly red.

Li Qinzai smiled: "If this is the case, it is really gratifying, and the ancestral graves of your families should be full of gun......smoke at this time."

Li Sujie was taken aback, and hurriedly corrected carefully: "Sir, it should be 'green smoke'......"

"Well, that's what I mean, the ancestral tomb is smoking, and you're out of breath."

Li Qinzai smiled and nodded at Xuancheng in the crowd, which was regarded as a compliment to her. Diaphragm

Xuancheng blushed with shame, and suddenly covered his face and stomped his feet shyly, a typical little fan girl.

Li Qinzai grinned, tsk, why is the princess's face so thin, think about the princess in her previous life, the guests took off their pants in the box, they didn't blush, the oil seller is only familiar with his hands, they are only familiar with his eyes.

…………

Another powerful firearm came out, and it was of great significance to the Tang military, and it was impossible to hide the news.

After the test, he left Ganjingzhuang on a fast horse and galloped desperately towards Chang'an City.

The little bastards stood in place in a daze, and after a long time, Li Sujie gritted his teeth, turned around and walked towards the school.

The rest of the bastards followed him with awe-inspiring expressions. Diaphragm

Perhaps only when they truly see how powerful Mr.'s knowledge is, will they remember it deeply in their hearts and take the initiative to learn.

Li Qinzai had been begging for a problem that could not be solved, but a mine woke them up, and they knew that when the school first opened, they should have made a mine and buried it at the gate, and killed these turtle grandchildren.

Li Qinzai stretched his waist and walked back with buckwheat, the pits blown up on the ground, as well as the blood stains and internal organs all over the ground, of course, these finishing work was handed over to the subordinates.

Buckwheat was very excited, looking up at Li Qinzai's small eyes, with a different light, like a lantern guiding the way in the night.

"Dad is so powerful, he is great at doing anything, as soon as he makes a move, he will shock the brothers to the ground, and the new gadgets made by Dad are also powerful, especially loud."

Li Qinzai smiled and said: "You said that there will be movement in the New Year, this movement is big enough, right?" ”

"Well, it's loud enough, the whole Zhuangzi's ground trembled, and the child's ears were about to be deafened...... "Rang."

Immediately, Buck's little appearance looked at him with both apprehension and expectation: "Can you play with the new gadget made by Daddy?" ”

Li Qinzai's eyelids jumped, glared at him and said: "You remember for me, what my father just made, don't say you can't play with it, you can't even touch it, you can't think about it, you can see the fate of that sheep clearly, do you think it's better than it?" ”

Buckwheat sighed and was completely dead.

"Okay, Dad, if the child doesn't care, it's ......," Buckwheat said aggrievedly.

Li Qinzai glanced at him: "You look like you're unwilling to lose your money, it's hard for me to believe you." Why don't I help you calm down? ”

Buckwheat looked at him suspiciously: "How can you calm down?" ”

Li Qinzai looked around, the heavy snow in Guanzhong had stopped for a few days, but the snow on the side of the road was still deep, and his feet were more than a foot high, and every step was very difficult. Diaphragm

Li Qinzai blinked evilly, suddenly picked up Qiao'er, chose a piece of snow that was the whitest and thickest, and threw him into the snow......

Buckwheat screamed in mid-air, dancing with her hands, and the last one planted the onion upside down, and plunged headfirst into the snow, leaving only a pair of small short legs to plane and kick outside the snow.

Li Qinzai laughed.

Of course, having a child is for fun, otherwise what's the point?

…………

The news of Li Qinzai's creation of a mine soon spread to the Taiji Palace.

Li Zhi and Empress Wu were stunned, from the description of the knight, Li Zhi suddenly found that the new firearm created by Li Qinzai this time was so powerful, the important thing is that the annihilation of the enemy army is invisible, if it is used on the battlefield, it will be a sharp weapon that will make the enemy fearful. Diaphragm

The imperial court is now quietly preparing for the grain, grass and ordnance of the Eastern Expedition, the soldiers are also working the cold days, the state apparatus is slowly activated, and everything is preparing for the Eastern Expedition.

At this time, Li Qinzai created a powerful new firearm, which was like a tiger with wings for Li Zhi.

Even if Li Zhidang paid attention to it, without saying a word, he summoned several veterans from the DPRK and China, and the group drove straight to Ganjingzhuang.

Li Zhi and the veterans must see the power of this firearm with their own eyes before they can calmly make tactical arrangements, and perhaps, its appearance will change the original strategy set by the veterans.

Not to mention anything else, if the mine is really useful, then after mass production, use it to block the enemy's retreat, the only way, the Tang army can concentrate superior forces and focus on annihilating Goguryeo with the momentum of a lion fighting a rabbit.

This is the magical role that a new firearm can play on the battlefield, and it is not an exaggeration to say that it can change the existing strategy.

It was already afternoon when the monarch and ministers arrived at Ganjingzhuang, and Li Qinzai was informed by the eunuch in advance, so he led his subordinates to wait at the entrance of the village. Diaphragm

Li Zhi did not take a Luan car, but came on horseback himself, followed by many veterans, as well as thousands of black forest guards.

Seeing Li Zhi dismount at the entrance of the village, Li Qinzai hurriedly bowed and saluted, and as soon as he bent down, Li Zhi held his arm.

"It's such a time, what kind of courtesy, quickly show me your newly created firearm, it's called 'landmines', right?"

Li Qinzai said with a smile: "Yes, the minister's boring drama for a while, I never thought that it would alarm the holy driver, and the minister's sin was also ......."

"If you talk about it again, I'll really cure your sins, let's go, take me to see!" Li Zhi grabbed his wrist and walked towards the courtyard.

"Ah, Your Majesty, don't be busy, don't be busy, the ministers will greet the old generals and elders first......"

Li Zhi frowned, and before he could get mad, Li Qinzai's ass had been kicked hard. Diaphragm

Li Qinzai was furious, but turned his head and saw Li Tao staring at him unkindly: "The old man kicked it, what's the matter!" ”

Li Qinzai suddenly turned off the fire: "Don't you, you're scared." You're always kicking well, and you're happy. ”

A group of old killers behind him nodded with a smile: "That's right, it's really happy." ”

Walking with Li Zhi towards the open space that had already been selected outside the courtyard, Li Qinzai unconsciously took a few steps behind, side by side with Li Tao, and said in a low voice: "Grandpa, why do you have to run around in person at this age, you have the generals to witness with your own eyes, what are you not worried about." ”

Li Tao shook his head and said in a deep voice: "No, the old man must witness it with his own eyes." ”

Li Qinzai wondered: "Why? ”

Li Tao didn't answer, but Li Qinzai's mind suddenly flashed with inspiration. Diaphragm

He remembered that in the history books of his previous life, the Tang Dynasty conquered Goguryeo this time, and the commander of the army was Li Tao.

If nothing else, this time Goguryeo was finally destroyed, and Li Tao also completed the last feat in his life, ending perfectly with the destruction of the country, and it will be brilliant for thousands of years.

Li Qinzai's heart moved, and he suddenly said: "Grandpa, in the battle of Goguryeo in the east, my grandson asked Ying to accompany the army." ”

Li Tao smiled: "Although you are not very greedy for life and afraid of death, but you are not a hero, you have always been able to avoid the killing of swords, why did you take the initiative to ask for help this time?" ”

Li Qinzai licked his dry lips and said in a low voice: "My grandson wants to witness my grandfather's immortal achievements, is this reason enough?" ”

Li Tao was silent for a moment, and suddenly burst into laughter: "Good, good!" My Li family is a good person! Don't cowardly! ”

Li Qinzai was extremely glad at this moment that he had created a mine on a whim before the Eastern Crusade, which added a few more points to the victory rate of the Tang Dynasty's war to destroy the country. Diaphragm

Li Zhi walked in front, turned his head and disappeared Li Qinzai, so he turned around and beckoned to him.

Li Qinzai stepped forward, and Li Zhi smiled and said, "I haven't asked you yet, why did you suddenly create this thing?" ”

Li Qinzai touched his nose and said with a wry smile: "The minister's dog said that the New Year is approaching, and there is no movement in the Zhuangzi, and it is not lively enough, so the minister built a mine and gave him a fierce blow to scare him......"

Before he finished speaking, his ass was kicked again, and he didn't have to look back to know that the murderer was Li Tao.

"The Son of Heaven asked, give the old man a serious reply!" Li Tao shouted behind him.

Li Qinzai had no choice but to say: "Your Majesty is about to go east, the minister is worried about His Majesty, and he can't sleep at night, fortunately the heavens have mercy, and a spiritual light is injected into the minister's heavenly spirit cover, and the minister has an epiphany in an instant, so he created this thing, helping the king to be invincible and sweep away Goguryeo!" ”

Li Zhi was silent for a while, and sighed: "Although I know that it is a nonsense to fool me, I have to say that this nonsense is actually quite listening, so I should take it as true." "Ahh
