Datang: Huchi served as a bodyguard, but refused to enter the court as an official

laugh--

This time, the fuze was more than twice as short as before.

Less than five breaths after ignition, the shotgun was shot out.

boom--

The sound was more muffled than when playing with an iron core.

The wheels under the cannon did not move, and it seemed that the recoil force was much less.

Li Er put his hands on his eyes, facing the sun, squinted his eyes, and looked into the distance.

He was very confident.

It's just aiming. For those who are good at archery, it's just a child's play.

But to his surprise, the shell landed on the east side of the beast tide, more than 30 feet away.

With such a long distance, even if the shotgun bullets were powerful enough, they would not be able to reach the beast horde.

Li Er was puzzled and said to the craftsman, "The method you said doesn't work?"

The craftsman hesitated for a long time, but did not say why.

They are regarded as R&D personnel, and how to use them requires specialized personnel.

Liu Bai smiled and said, "Your Majesty, it's better to let Chengqian come."

Before Li Er could speak, Li Chengqian immediately jumped up.

He pointed to his nose in disbelief and said, "Me?"

Liu Bai rolled his eyes at him angrily, and said, "After studying in the academy for so long, have you learned it in the stomach of a dog?"

"But I've never played with this thing before!"

Li Chengqian was not confident.

Calculating the distance, the beast horde was less than three miles away from them.

In other words, if he couldn't disperse the beast tide with this shot, he would have to run for his life.

Liu Bai said bitterly, "Think about the knowledge you learned in the academy, and see if you can use it!"

Li Chengqian looked around in confusion, almost crying.

This time, Cheng Chumo's reaction was faster than his.

"I see!"

Cheng Chumo yelled loudly, gathering everyone's attraction.

Liu Bai was also very surprised, when Cheng Chu was lying on the ground with his butt pouted, Liu Bai knew that Cheng Chu was thinking right.

Li Er was very curious, walked over and looked at Cheng Chumo on the ground, writing and drawing a lot of messy symbols.

Li Chengqian slapped his forehead, and said angrily: "How could I forget this formula! Damn it!"

While speaking, Cheng Chumo had already finished his calculations.

Excitedly, he ran to the cannon, used his arm as a ruler, made a few gestures, and said to the craftsman, "Bring the fire stick!"

Chapter 801 The Earliest Thermal Weapon Troop in History

Calculating the parabola formula is a very basic knowledge of the academy.

Even Li You and Li Yin's preschool can use it well.

Just now, Li Chengqian just didn't feel puzzled for a while.

Cheng Chu silently lit the fuse and waited for a few breaths.

boom--

The cannon spewed out flames, and the shot fell into the beast tide almost instantly!

Rumble!

Roar!

The sound of shells shattering, mixed with the roars of countless beasts, presented an extremely bloody scene before everyone's eyes.

A large number of broken porcelain pieces and irons, in the explosion, turned into a rain of tiny arrows, the power is amazing!

At least thirty beasts were disemboweled in an instant and turned into a puddle of minced meat.

The beast horde was suddenly disrupted.

More beasts were trampled to death by the frightened beasts behind!

Cheng Chumo jumped up and shouted excitedly: "It's a hit! It's a hit!"

Liu Bai went up and gave him a head.

"It's hard to use your brain, but you don't pay attention. Think about it carefully, where should you hit!"

Cheng Chumo's excitement dissipated immediately.

Not only because of Liu Bai's words, but also because of that shot, the beast horde suffered countless casualties.

But the remaining beasts were not affected much.

Those who should run towards them still continue to run.

It seems to be even more angry!

Cheng Chumo panicked a little.

He hastily re-stuffed the shotgun, and worked with the craftsmen to add medicine and twist.

After recalculating the parabolic formula, just as he was about to ignite, he suddenly remembered what Liu Bai said just now.

"How can we change their course?"

Cheng Chu said silently.

He squinted his eyes for a while, and suddenly moved the muzzle to the left a little.

Then, light the fuse!

This time, the shell did not land in the middle of the beast tide.

Instead, it landed on the right side in front of the beast tide.

Rumbling--

Slightly less beasts shredded by shotgun.

However, the beast at the front turned around in fright.

The beast behind also followed the beast in front to the south!

Li Chengqian cheered, and the worries in his heart completely disappeared.

Li Er and Cheng Chumo did not say a word.

The two seemed to have realized something, lowered their heads and pondered.

They are all people who have led soldiers and fought in battles. Cheng Chumo has less experience and is better at accepting new things than Li Er.

After what happened just now, they suddenly discovered that the use of cannons was not purely to kill or injure the enemy.

But to achieve a certain purpose.

Just like just now, their purpose is not to drive out all the beasts.

Just changing their direction is enough.

Therefore, the shell does not have to fall in the exact center.

It's the same as marching and fighting.

The important thing is not to kill all the enemies, but to win the battle!

The use of cannons is more strategic.

It is not to say that the greater the lethality, the better the effect on the battlefield.

Cheng Chumo suddenly lay on the ground again and calculated for a long time.

After finishing the calculation, he got up and turned the muzzle again.

Three times, five divisions, two times, do a good job of preparation.

Rumbling--

The third shot is fired.

The explosion point fell on the right front of the beast tide.

really!

The beast tide changed direction again and headed towards the front left!

Cheng Chumo seemed to have discovered endless fun.

Do the math and fire a shell.

The frightening animal horde has now become Cheng Chumo's plaything.

Those who were driven by him circled around the hill where everyone was.

Li Er bowed his head to study the formula that Cheng Chu silently wrote on the ground.

In other words, he is also studying the teaching results of the academy recently.

Relatively speaking, mathematics is more difficult.

However, the parabolic formula is indeed the foundation, and it doesn't take too much effort for Li Er to understand it.

He must have studied it thoroughly, so Li Er went up and kicked Cheng Chumo away.

"Let me come!"

Now, it was him who drove the beast around in circles.

Li Er became addicted to playing, laughing loudly while ordering some medicine.

His brain is enough, the formula does not need to be written at all, it can be calculated directly in his mind.

The whole box of shotgun was gone.

His gaze fell on the box of iron-core bombs again.

If the craftsman didn't stop him, he would have to finish all the iron-core bullets.

"Your Majesty, let's take a break. If the gun barrel is overheated, it will easily explode!"

Li Er put down the booklet with some regrets.

He is rarely so happy.

Half an hour later, as it was getting dusk, a group of people walked down the mountain.

Li Er found a random reason and asked Li Chengqian and Cheng Chumo to defend the surrounding area.

Riding his maroon sweat horse, he and Liu Bai went hand in hand.

"Are you really going to let Cheng Chumo go to Gaochang?"

Liu Bai shrugged his shoulders, "His father has said everything to the end, so what can I do?"

Li Er chuckled, shook the short whip in his hand, and said: "This Manchu civil and military officer knows how to change your mind. His face is bigger than mine."

Liu Bai smiled indifferently.

"Chumo intends to go to the battlefield to fight for his future. I can't stop him. Besides, letting him go to Gaochang Kingdom may not be a bad thing."

Li Er nodded approvingly.

"Cannons must be used in a discreet way. If there are people who can make it, Cheng Chumo, that brat, is enough."

In his heart, the prototype of a new army has been constructed.

In the future, this group of people will be dedicated to serving the artillery.
