On the ground, the shells of a small caliber did not change much, because the hammer was sunk into the ground, neither exploded nor deformed.

Seeing this, Tang San was instantly overjoyed.

Really! This is indeed a solid metal cannonball!

Tang San had expected it as early as the morning, and now that he confirmed it, he was naturally overjoyed in his heart, because if it was the same complex chemical changes as the previous high-explosive bomb, he would not be able to figure out the principle and not be able to replicate it.

And now, this smaller-caliber artillery shell is made of solid metal, that is...... Can be reproduced!

Moreover, not only that, Tang San also firmly believed that if it was made with the iron essence forged and purified by his Haotian Hammer, the penetration power could be further improved, and it could be improved!

As long as it can be manufactured in large quantities, the prestige of my Tang Sect will definitely shock the entire Douluo Continent!

Tang San was overjoyed, he seemed to have seen that the name of the Tang Sect resounded throughout the continent, no one knew it, no one knew it, and everyone was admiring and wanting to join with hope.

After imagining it, Tang San turned around and walked towards the barracks......

After that, Tang San rested for a day in the military camp of the Star Luo Empire, and the next day, after breakfast in the morning, Dai Mubai invited Tang San to enter the big tent of the Chinese army and discuss countermeasures together.

In the big tent of the Chinese army in the Star Luo Empire, Dai Mubai sat in the first place, his complexion was ruddy, full of energy, and he was even a little high-spirited.

In the sneak attack in the early hours of yesterday morning, although the Star Luo Empire paid huge sacrifices, and the number of casualties was far greater than that of the Wuhun Empire, Dai Mubai and others successfully mastered the use of artillery.

Dai Mubai looked at Tang San and asked what he was thinking expectantly.

"Little San, how is the artillery researched? Can it be imitated? ”

Below, Tang San smiled and nodded.

"Brother Dai, I have successfully mastered the shell and gun mount structure of the artillery gun I brought back yesterday, and I will be able to let Tang San copy and manufacture it in large quantities in a few days, but it ......"

Tang San frowned.

"But what?" d

Dai Mubai was a little worried.

Tang San frowned, looked at Dai Mubai, and sighed.

"Hey, Brother Dai, I can only understand the smaller caliber artillery I brought back, which is obviously used to snipe high-level soul masters, and the cannonball is a solid steel cannonball......"

Tang San didn't know what modern scientific principles such as pressure were, but he could also infer through his imagination that the smoothbore armor-piercing cannon shells did not explode, but only had penetrating power, and they must have been used to target some high-defense targets, such as high-level soul masters.

High-explosive shells, on the other hand, are used to deal with cluster targets, such as a large number of ordinary soldiers gathered together.

Tang San continued to speak as he thought about it.

"However, the larger caliber cannon we brought back, the shells still can't be disassembled, I can't reproduce it, or that sentence, if there is a design structure drawing, with my genius mind, I can restore it perfectly."

The corners of Dai Mubai's mouth tugged hard, then he laughed and waved his big hand.

"Xiao San doesn't have to blame himself, it's already very good to understand the method of use and copy that small-caliber cannon, tomorrow you will ask the people of the Tang Sect to quickly whip back to Gengxin City, make it in large quantities, and buy all of them from my Star Luo Empire."

After Dai Mubai finished speaking, several officers below were suddenly very unhappy.

The capture of these artillery, the army of the Star Luo Empire has made a lot of efforts, and the loss of soldiers is even thousands, how can it be said that there is a credit to the Star Luo Empire, why do you still have to buy it?

A senior officer hugged his fist at Dai Mubai, his face a little dark.

"Commander Qiqi, our army has suffered huge casualties for these artillery, we think that our army also has at least half of the credit for these artillery, and the secret of the artillery should be shared and announced to our army, so that we can also mass produce and improve combat effectiveness."

When Dai Mubai heard this, he immediately looked at Tang San.

He looked at Tang San and didn't speak, just waiting for Tang San's answer.

After being with Tang San for so many years, Dai Mubai knew that his third brother was very generous in some things, but he was stingy in some things.

One of them is Tangmen's core technical secrets.

Tang San didn't even tell his own father such a secret.

Dai Mubai wanted to know if his third brother would tell him the secret, because, according to common sense, the military of the Star Luo Empire did have merit, which was obvious to all.

In the first place, Tang San's face was ugly, he lowered his head, and the expression on his face was like he was going to eat someone.

Dai Mubai looked at it and knew that it was impossible for his third brother to tell him the secret, so he could only sigh inwardly.

Ay......

It's just a few bucks.

Dai Mubai comforted himself in his heart, faced Tang San, and smiled heartily.

"Hahaha, junior, it's okay, after you make artillery from Tangmen in the future, you will give priority to supplying our army, and the materials will be provided by our army, and you will only charge labor fees, how about it?"

Dai Mubai's proposal was already a great concession, and even Xiao Wu, who was sitting next to Tang San, felt that his eldest brother was too good to Tang San.

Hearing Dai Mubai speak, Tang San's face looked much better, and he raised his head slightly, squeezing out a hint of a smile.

"Then according to Brother Dai's instructions, it will be done."

With that, Tang San stood up.

"Without further ado, I'll draw up the design drawings now, let my Tang Sect disciples expedite the express delivery for eight hundred miles, and rush back to Gengxin City in the starry night, so that the Tang Sect can step up production."

"Good!"

Dai Mubai's eyes were scorching, with the artillery of the Tang Sect copying the Wuhun Empire in large quantities, he would be able to compete with the Wuhun Empire on the frontal battlefield, instead of hugging up in the mountains and forests every day to fight guerrillas.

After many days of guerrilla warfare and night raids, Dai Mubai was angry, once upon a time, his evil eyes and white tiger's domineering prestige needed to act in such a cowering way?

Inside the tent, everyone said a few words, and Tang San was ready to walk out of the tent.

But at this moment, suddenly, the camp tent opened, and a soldier ran in quickly, knelt down in the camp tent, held a note in both hands, and presented it to Dai Mubai.

"Newspaper, make a flying pigeon biography!"

Dai Mubai waved his hand.

"Bring it in."

"Yes!"

The soldier responded respectfully, got up, came to Dai Mubai, and handed over the note.

Dai Mubai took it, opened it and looked at it.

On the other side of the first place, Ma Hongjun's face shook with two whiskers.

"Boss Dai, what are you talking about?"

Dai Mubai put down the note, looked at Ma Hongjun, and then looked at Tang San with an inquiry on his face.

"Little San, the letter said that a large number of planes from the Martial Spirit Empire flew from the north yesterday, some of them landed in Notting City, and the other part landed in Longxing City, what do you think?"

Airplanes?

Tang San frowned slightly, he had a lot of questions and puzzles about airplanes, and he didn't know the military usage of a large number of airplanes.

After thinking about it for a while, Tang San was about to shake his head.

But at this moment, on the other side of the tent, Yu Linglong, who had willow eyebrows and phoenix eyes, turned her head and looked at Dai Mubai with some concern.

"Brother Dai, can you tell me how many planes from the Martial Spirit Empire are here? Also, what are their aircraft types? ”

Dai Mubai turned his head to Yu Linglong and blinked suspiciously.

"The letter said that there are probably more than two hundred, among them, there are dozens of particularly large heavy bombers, and the small ones that can dive can dive at least more than two hundred, Seventh Sister, what's wrong?"

Yu Linglong was startled and stood up suddenly.

"Oh no, Brother Dai, we must run for our lives immediately! The Wuhun Empire is likely to launch a large-scale air raid! ”

"What?!"

Dai Mubai's eyelids jumped vigorously, and his face was incredulous.

"Seventh sister, what's going on? Tell me more about it. ”

"Hmm."

Yu Linglong nodded, took a deep breath, recalled the information she had seen before crossing in her previous life, glanced at everyone, and spoke eloquently.

"Brother Dai, ladies and gentlemen, in my time, aircraft used to be the biggest force that determined battlefield superiority, and whichever side gained air supremacy was equivalent to grasping the initiative in war.

And in all wars, there is only one possibility of suddenly transferring a large number of bombers to the front line......"

Yu Linglong's eyes are certain.

"That's it...... Carpet bombing, massive air raids! ”

At this point, Yu Linglong's face became a little frightened.

"Once carpet bombing is carried out, a radius of hundreds of miles will be a target for aircraft bombing, and the enemy will attack all areas.

There will be massive bombardment, whether there are people, civilians or troops, and it will be too late if we don't hurry up and evacuate. ”

What the? Is there anything else?

Dai Mubai was startled, then got up and gave orders.

"Everyone, act immediately, mobilize all the soldiers, give up Zizhong, only bring the necessary food, grass and weapons, and march to the south, and be sure to evacuate this place before the indiscriminate bombardment of the Wuhun Empire!"

"Yes!"

Many officers stood up and responded solemnly.

Subsequently, Dai Mubai and the others went out of their respective barracks, and the hundreds of thousands of troops of the Star Luo Empire hurriedly packed up and marched quickly south.

Because of the hurry, many siege equipment, heavy shield iron armor, movable giant crossbows, etc., were abandoned on the spot.

Just after the evacuation of the Xingluo army in the morning, in the afternoon, just after three o'clock, there was a sudden rumbling sound in the northern sky.

The thunderous noise was getting louder and closer.

Finally, after a short while, a large number of planes flew in from the north, densely packed, and a large area of black oppression covered most of the sky, and the whole land was darkened, as if a large dark cloud was about to rain!

It's just that these clouds are made of iron.

In the sky, the huge White Eagle 36 heavy bombers lined up in a triangular formation, and they opened the huge hatches under the belly of the plane, dropping huge aviation incendiary bombs one after another.

"Boom, boom, boom......!"

The huge mushroom cloud flame vine rose into the sky, and the burst of fire soared dozens of meters into the sky!

Countless trees were set on fire, making a crackling pop.

The air shook and twisted, countless black smoke rose up, and a large number of animals fled in terror, but within a few steps, as soon as they touched the smoke of the flames, they fell to the ground in dizziness and died on the spot.
