Boom, boom!

The 75 rapid-fire cannons fired one after another, shattering the steel barriers at the gate of the city. Several guards on duty with steam rifles were also hit by broken shrapnel and fell to the ground not knowing whether they were alive or dead.

Those who were queuing up in front of the city gate and waiting to enter the city suddenly became like birds and beasts and fled in all directions when they saw Zhang Tuohai dared to fire at the city gate.

The defenders on the city wall never expected that someone would dare to bombard the city gate in broad daylight. They were stunned for a moment and almost didn't react.

After waiting for a few seconds, they came to their senses and turned their guns to prepare for a counterattack.

But at this time, classmate Xiao Ai had already pointed 26 steam machine guns at the city wall.

Da da da.

The dense metal storm hit the city wall, causing bricks and earth to fly, making the defenders unable to lift their heads.

Taking advantage of this gap, Zhang Tuohai drove an infantry fighting vehicle and rushed into the city gate.

Inside the city gate is a small square. Zhao Wanwan's six-wheeled off-road vehicle is parked in the center of the square, surrounded by eight steam tanks, blocking the off-road vehicle's escape route.

Those steam tanks were covered with thick riveted armor, and a large-caliber cannon was installed on the turret. There was thick black smoke coming from the chimney at the rear of the vehicle, making it difficult to deal with at first sight.

Among these steam tanks, there were hundreds of infantrymen armed with steam rifles.

This lineup, let alone Zhao Wanwan, would not be able to break through even if it were ten times larger.

Nothing else, as long as she dares to move, those steam tanks will smash her into pieces.

This situation is a dead end for Zhao Wanwan.

But, not for Zhang Tuohai.

"Classmate Xiao Ai, throw anti-tank missiles! Kill those tanks!"

Zhang Tuohai said loudly.

These steam tanks are the real enemies because they have the ability to destroy Zhao Wanwan.

"clear!"

Following Zhang Tuohai's order, the steam machine gun in the robotic arm's hand turned into an anti-tank grenade and was thrown towards the steam tanks.

Boom!

Anti-tank grenades fell on the steam tank and exploded.

These anti-tank grenades can even deal with Tiger tanks, let alone these steam tanks.

Moreover, these old-fashioned steam tanks do not pay attention to human-machine coordination at all, and they have no shock absorption and noise reduction equipment at all.

Even if the anti-tank grenade cannot explode the rivet armor outside the tank for a while, the violent vibration is enough to temporarily incapacitate the drivers in the tank.

In the blink of an eye, eight powerful steam tanks lost their combat capabilities in a short period of time.

Bang bang bang.

Some alert infantrymen also reacted and hid behind the steam tanks and began to fight back.

The bullets from the steam rifles rattled the infantry fighting vehicle.

A few sharpshooters even broke the joints of several robotic arms, causing several robotic arms to lose control.

"Kill them with the Pursuit Cannon!"

Zhang Tuohai shouted angrily.

These robotic arms are his treasures. Each of them consumes three units of high-grade metal ingots. Normally, his treasures are extremely precious, but they are lost here. Is this a big deal?

Boom, boom!

The revolving gun roared.

The pursuit artillery fired shrapnel shells.

The outside of the shrapnel shell is a thin layer of iron and is filled with densely packed metal projectiles. These shells explode on the enemy's head, and the metal projectiles inside are fired in all directions driven by the shock wave, providing complete 360-degree coverage without blind spots.

After two shrapnel grenades.

There was no infantryman in the square who could stand up anymore.

The unprotected infantrymen were completely torn into pieces by thousands of metal projectiles and turned into minced meat on the ground.

As for those steam tanks, they were very strong. There were many metal projectiles embedded in the outer rivet armor, but none of them penetrated the armor.

"It's really strong."

Zhang Tuohai snorted coldly.

Then, he controlled the robotic arm to throw anti-tank grenades into the barrel of the steam tank.

No matter how thick your armor is, can the gun barrel be so strong?

Boom!

A violent explosion sounded.

The steam tank's gun barrel was blown out, and a large dark hole was exposed at the turret connection. Only half of the driver's body was left inside.

Seeing that it was effective, Zhang Tuohai followed the prescription and killed the remaining steam tanks one by one.

"How are you? Are you injured? Can you still move?"

Zhang Tuohai asked Zhao Wanwan.

"No problem, I can still move." Zhao Wanwan quietly wiped the tears from the corners of her eyes.

She never expected that Zhang Tuohai would rush in to save her.

With eight steam tanks and a hundred infantry, isn't he afraid of death?

"It's okay, just rush out with me."

Bang!

A dull sound came from behind.

Zhang Tuohai looked back and found that the city gate had been closed at some point.

And a huge brass gate slowly lowered from the top of the city.

It is nearly one meter thick and is extremely strong.

The defenders on the city wall also reacted, turning their guns and artillery to prepare to surround and annihilate the two men.

"I accidentally let you fall in. I'll hold them back. You can find a chance to rush out."

Zhao Wanwan said.

"No, there is still a chance."

Zhang Tuohai also has 8 Kornet anti-tank missiles, which can blast a gap in the city wall and rush out.

Just when Zhang Tuohai was about to take action, the prompt system rang.

[It is recommended to retreat backwards. At this time, the defenders in the city have not fully reacted. There is a factory at 8 o'clock. The defense there is very weak. There is an abandoned intercity subway tunnel below the factory. You can leave from there. 】

Zhang Tuohai's eyes lit up, and he turned the camera. Sure enough, there was a huge factory at the eight o'clock direction. It had iron walls, thick chimneys with billowing black smoke, and bursts of roaring mechanical sounds from time to time.

From time to time, groups of soldiers carrying steam rifles patrolled, but their firepower was far inferior to that of the city wall.

"That's it!"

"Follow me!"

Zhang Tuohai said hello, turned the car and rushed towards the factory.

The defenders on the city wall became anxious when they saw this. That factory was very important. If it failed, it would be a huge blow to the entire Gray Rock City.

However, it was too important there, so the artillery was a defensive weapon and did not dare to fire.

Due to the range and angle issues of those steam machine guns, only a small number of them could attack Zhang Tuohai.

These bullets were like nothing to Zhang Tuohai, who had two layers of armor. Apart from dropping some rivets, the damage was almost zero.

The patrolling guards saw someone rushing over and quickly organized a counterattack.

But before they could disperse, a shrapnel hit their heads.

With a loud noise, a group of soldiers turned into minced meat.

Bang!
Chapter completed!
