The scope was also Chen Yan's suggestion, and it turned out to be very useful.

Boom!

Chen Yan pulled the trigger, and a cloud of gunpowder smoke rose up, and there were many large holes in the target five hundred meters away that were still smoking.

Chen Yan exhaled slowly, and the expression on his face looked very satisfied.

"Guo Qing, this rifled gun is quite good, find a way to mass produce it as soon as possible."

Guo Jiangtou scratched his head and said with some embarrassment.

"But my lord, this rifling is really not good."

"Since it's hard to do it manually, let's find a way to do it with a machine, haven't you been using a machine tool to polish the barrel recently? Wouldn't it be nice to change the drill bit? ”

Chen Yan said.

"King, the power source of the machine tool is unstable, whether it is water power or animal power, it may be okay to polish the barrel, but the rifling wire is a very delicate job, I'm afraid it won't work."

Guo Craftsman said.

Chen Yan bowed slightly, the power source was unstable, and he couldn't help it.

The ideal solution is a steam engine, but with the current technical conditions of the Qin State, it is almost impossible to build a steam engine.

Even if it can be reluctantly made, I'm afraid it's a kind of product that can only be seen but not used.

In fact, in the final analysis, it is a question of the industrial base.

Basic Materials, Finishing, Chemicals, Physics......

These are the cornerstones of an industrial development.

Chen Yan couldn't solve this problem for the time being, unless someone could fully learn the books he copied.

Let's build a complete industrial system from scratch!

Although it is not absolutely impossible, the books copied by Chen Yan are a complete set of textbooks from elementary school to university, and if you want to learn it thoroughly, no matter how genius you are.

A few years is not enough!

Moreover, the establishment of a complete industrial system is not something that can be done by one person or two, but must be done by a large number of super geniuses working together.

And this time will be even longer, 10, 20, 30 years...... No one knows how long it will take.

Just like in later generations, China's industrial system took decades to build from scratch, and even then, in some ways, it will be stuck in the neck.

As for Chen Yan himself, although he has a perverted memory, there are some things that cannot be memorized.

He has traveled from the afterlife, and although the knowledge system in his mind is complete, he is not the kind of science genius, and he knows a lot of things.

It is almost impossible for him to set out to build a complete industrial base!

……

Chen Yan came out of the test range, escorted by a team of captives, and prepared to return to the palace.

It's just that when Chen Yan's royal car entered the city gate, something happened happened!

Whoosh ......

The sound of sharp arrows piercing the air rang out.

Puff puff......

Several of the captive sergeants were caught off guard and were shot by arrows, making a sound of arrows piercing flesh.

The arrows of the arrows were smeared with strong poison, and in the blink of an eye, the soldiers were blackened and died.

"Be careful, protect the king!"

"Enemy attack! Enemy attack! ”

"Protect the King!"

“……”

However, the well-trained Dang Capture Army did not panic in the slightest, and quickly formed a formation to protect Chen Yan in the center.

Chen Yan's royal car is surrounded by groups!

Chen Yan's face was extremely gloomy, and the robe on his body was covered with bloodstains, but it was not his, but a sergeant who was responsible for protecting him closely.

An arrow was aimed at Chen Yan, and the young soldier stepped forward without hesitation to block in front of Chen Yan, using his body to block the attack for Chen Yan.

And he lost his young life!

Chen Yan didn't know whether it was grief or anger, or both.

Chen Yan remembered the name of the soldier who helped him block the arrows, his name was Wang Dong, he was the only male in the family, he had a lovely daughter, a gentle and virtuous wife, and an old mother who was still sick.

Usually Chen Yan gets along with these soldiers, without the slightest arrogance, often eats and drinks with them, braggs and farts together.

Chen Yan will never forget Wang Dong's happiness and satisfied expression when he talked about his lovely daughter at home.

But now, it's gone!

Nothing!

Wang Dong died, he died for Chen Yan!

If Wang Dong hadn't come forward, maybe it would have been him who died at this time!

Chen Yan was angry, he was completely angry!

He thought that the group might rebel, but he didn't expect them to be bold enough to attack him, the king of a country.

Damn, damn it!

Outside the royal car, the earth-shattering shouts of killing resounded, and the dense black-clothed people rushed out of the street corners, the houses on the side of the street, and the alleys.

Wield your weapon and kill Chen Yan's royal driver!

"Escort! Escort! ”

The soldiers shouted again and again, and they quickly retracted their defensive lines, lined up in a well-organized formation, and prepared to meet the enemy at any time.

"Kill!"

The shouts of killing rang out, and the man in black rushed to Chen Yan's royal car in a disorderly manner.

"Array, array!"

"Kill!"

"Ready, load!"

The captives began to load their muskets, then picked up their tongs and aimed at the men in black who were rushing to kill.

"Put!"

At the sound of an order, a neat burst of gunfire rang out.

Bang Bang Bang ......

The crisp sound of muskets rang out, the smoke of gunpowder rose, and lead shot at the man in black.

"Ah......h

The few black-clothed men who rushed to the front fell down as if they had been cut wheat, and the screams rang out, and blood burst out.

The body was torn apart by lead, and the internal organs and blood were sprinkled all over the street!

"Crossbow! Put! ”

Many of the men in black picked up their crossbows, then pulled the crossbow machine, and one arrow after another pierced the void and shot at the army formation.

"Raise your shield!"

The officers of the Dang Capture Army gave the order in unison, and the Dang Capture Sergeant took the order and raised his shield.

Oooooooo......oo

The arrows hit the shield of the Swinging Army, making a crisp sound and splashing sparks, but it was not able to break through the shield defense of the Swinging Army.

"Load, put!"

The Swing Sergeant stretched out his musket from the gap in his shield, and the muzzle of the black hole was aimed at the swarming men in black.

Bang Bang Bang ......

The muskets of the captives fired another volley.

The man in black fell again in a large area, blood spraying everywhere.

"Thunder! Throw. ”

One by one, the black sky-shattering thunderbolts were thrown out, and black smoke emitted from their tails, falling into the crowd of black-clothed people.

Boom Boom!

The roar rang out, and the bodies of countless men in black were torn apart by the terrifying shockwave, and one man in black was torn open by shrapnel, and his white brains and blood were mixed together.

"Kill!"

It's just that although the Swinging Army caused terrifying damage to the people in black, the Men in Black still relied on their numerical advantage to rush to the front of the Sweepers.

The two sides fought together in an instant, and the well-trained Dang Capture Army showed Mo Qiang's combat effectiveness in an instant.

All the soldiers raised their shields in unison, and then swung away the attack of the men in black, and then waved their long knives in unison, and the bright sword light flashed, and countless people in black poured a large piece in front of the army formation.
