"What is this?"

"We'll see!"

"By the way, this wall made of cement is good!"

"Yes, if it is used on the city wall to defend against the enemy, it is definitely easy to use!"

A group of high-ranking generals whispered, and many of them whispered about this ring fortress.

"Childe."

Cao Zhengchun took out a piece of sworn cotton from his sleeve, tore off a small piece and handed it to Fusu.

Cotton cultivation has a long history, starting in 800 BC, that is, during the Warring States period, when cotton was planted and spun.

Fusu took the cotton, divided it into two pieces, crumpled it into a ball, and stuffed it into his ear.

"Childe, what are you doing?"

A group of generals looked at each other, not understanding why Childe suddenly wanted to plug his ears.

At the same time, Liu Ji also took out cotton to block his ears, and also divided a small piece and handed it to Zhong Liang and Meng Tian.

The two of them looked at each other without knowing why, but they did as they did.

Fusu turned his head to look at the confused generals, and said with a smile: "Give it to them." ”

"No!"

Cao Zhengchun hurriedly bowed down to answer the order, took out the cotton and said with a smile: "It will be loud later, and the generals should plug their ears." ”

Everyone took the cotton, their faces puzzled.

Some people immediately blocked their ears in the same way, and some people looked unconvinced, and raised their heads with pride.

As a general fighting on the battlefield, if he is frightened by the sound and plugs his ears, wouldn't he lose face!

Fusu just glanced at it and turned his head.

Since there are a few people who don't want to plug their ears, it's better to teach them a lesson at that time.

Soon, the herald stood on a high place, raised the flag in his hand, and kept his eyes fixed on the direction of the barrier.

Cao Zhengchun saw that Gongzi was ready, and waited to see the experiment with his hands behind his back, so he immediately turned around and waved his hand down.

Seeing this, the herald immediately waved down the flag in his hand.

Suddenly, white smoke rose from the dirt pit hundreds of meters away, accompanied by flames.

Someone muttered in surprise, "What's that?" Fire oil, set fire to the mountains? ”

Unfortunately, everyone's eyes were fixed on the white smoke in the distance, and no one answered the question.

As the white fireworks flickered rapidly, it took a few breaths to burn to the position of the mountain wall.

Rumble!

Suddenly, a deafening explosion sounded, and even a slight vibration was sent from underfoot.

Under the gaze of everyone, the mountain wall suddenly crumbled, large pieces of debris splashed, thick smoke and dust filled the air, and the scene at the mountain wall could not be seen clearly.

The generals were startled by the sudden change, and stood in the barrier in a daze, feeling the strong wind hanging on their faces, and they couldn't come back to their senses for a long time.

Gradually, the smoke and dust dispersed in the breeze.

The originally steep mountain wall has a huge crater three meters deep!

At the edge of the crater, the rocks crumbled, and deep cracks spread like spider webs!

The mountain wall, which was intact a moment ago, became unrecognizable in the blink of an eye.

The people present were all veterans of the battlefield, and they had never seen such a burst of sight.

Boom!

Suddenly, a huge rock hanging from the mountain lost its support, fell off and slammed into the ground.

In the distance, the hearts of the generals also jumped, and they recovered from the shock!

Fusu bowed slightly, a satisfied smile on his face.

Meng Tian was also stunned and took out the cotton ball stuffed in his ear, and asked in shock: "Father-in-law, what is this?!" ”

Fusu raised his head, an unfathomable smile on his face.

"This is explosives, made by Childe's idea!" Liu Ji explained with a smile, and he was also surprised in his heart.

The development of gunpowder was completed by Liu Ji.

As a former military advisor of Zhu, he naturally knows the formula of gunpowder.

In a conversation, Fusu felt that he was not an engineering student, so he casually asked if the military advisor knew about gunpowder.

Unexpectedly, Liu Ji wrote out the formula of gunpowder casually!

At this moment, Fusu immediately won a treasure.

It was obviously impossible to build guns, and the open area of the smelter on Blackforest Slope was not yet at that level.

However, if you can't make guns, you can make explosives packs.

But as a superior, you don't need to be proficient in everything, otherwise what else do you need your subordinates to do?

Fusu only put forward the idea, and then handed it over to Liu Ji for research, and allocated funds to choose someone to build a gunpowder workshop far away from the county seat.

If you set up a workshop in a ravine, even if there is an accident or is destroyed by the enemy, it will not affect the people of the county, right?

Liu Ji also lived up to expectations, and in the limited information provided by Fusu, he groped for the development of the explosives package!

Meng Tian blinked in a daze, and said excitedly: "With the secondary weapon in hand, there is no gate that I can't attack with the army of Shangjun!" ”

Another general also chimed in: "That's right, can the city gate be stronger than the mountain wall!" ”

Suddenly, several generals around frowned, and said in a deep voice: "Lao Zhang, can you speak quietly!" ”

The general, known as Lao Zhang, blinked his eyes in surprise, and said in a loud voice: "Am I loud?" No? ”

Meng Tian turned his head and scolded with a smile: "Who told you to be stunned and not plug your ears, you deserve it!" ”

Suddenly, there was a hearty laughter all around.

These are all experienced generals in war, and when they see the mountain wall cracking, they know the power of explosives.

In the future, when attacking the city, there is no need for soldiers to push siege vehicles against the rain of arrows and boulders and hit the door.

All you need to do is rush under the city gate with explosives, and you can blow the city gate into sawdust in one go!

Without a city gate, it's much easier to capture a city!

Moreover, with the exception of the county seats, most of the county towns have walls made of adobe.

Such an adobe city wall will definitely collapse if it is blown up!

Even the thick walls of the county town can blow a big hole!

For the Shangjun army, with the assistance of explosives, there is no longer a need for soldiers' lives to fill in siege battles!

It can greatly reduce the casualties of soldiers who die in the siege and are killed by bows and arrows, big stones, and golden soup!

Fusu turned his head and asked playfully: "The future commander of the three armed forces, can he have a plan for the next war?" ”

Li Jing raised his eyebrows, and immediately bowed down and replied: "Back to Gongzi, I already have a plan!" ”

Fu Su raised his eyebrows, and he was also interested, and said, "Oh? Let's start with the upcoming 50,000 soldiers and horses in Donghu! ”

Suddenly, the other generals pricked up their ears, wanting to hear what good strategies the new commander of the three armed forces had.

In the end, how can he be valued by the prince just after he came, and he was named the commander of the three armies!

If Feng Mengtian is the commander-in-chief, with his family background and military exploits, everyone present will be convinced.

can parachute a coach, and I am more or less unconvinced!

Li Jing raised his head and said solemnly: "Then it depends on how many prisoners the son wants!" ”
