As soon as Cheng Qi died, this army of more than 5,000 people lost its commander at once and fell into a riot.

Before Cheng Su could take over the command of this force through long-range communication, Cheng Yanqiu rushed in with a force composed of pure evolutionaries, and in the chaos, Cheng Yanqiu and they directly captured all the dozen officers except Cheng Qi alive.

The process of persuasion was quite smooth, and after Cheng Yanqiu revealed his identity and ensured in the name of the future head of the Cheng family that these people's families would not be harmed, and they would not suffer any retaliation, these people all gave up resistance and handed over their weapons very cooperatively.

Cheng Yanqiu only had a few hundred people in his hands, and it was too late to deal with the surrender of more than 5,000 people, so Cheng Yanqiu simply let them reorganize the queue and garrison them in the residential area.

As long as Cheng Yanqiu can successfully take down Cheng Su, then these people will never make any senseless resistance, but if Cheng Yanqiu fails, then these people are likely to aim the guns in their hands at his back again, blocking his last retreat.

Merely...... In Cheng Yanqiu's plan, this time, there was no way out for himself after failure.

This time, he's not just trying to take back what belongs to him, but also to get revenge on his father.

Although there is a saying called "A gentleman takes revenge, ten years is not too late", Cheng Yanqiu never thought of himself as a gentleman.

Compared with it, he prefers the pleasure gifts of those heroes in martial arts stories, people like Cheng Su must die, and Cheng Yanqiu even feels that it is too luxurious to let him live one more day.

Vault 909, Tunnel Zero.

This is the only passage between the ordinary residential area of Vault 909 and the main residential area of the Cheng family, and through this tunnel, you can enter the real core area of Vault 909, where only the clansmen of the family head and the collateral serum of the family head within five generations of the family head can live, as well as the high-level personnel in the Cheng consortium.

The guards who were loyal to Cheng Su and completely sealed the Tunnel Zero with firepower, this tunnel was only less than three kilometers long, but Cheng Yanqiu and they were only halfway forward, and there were already nearly 100 casualties, and even the evolutionaries died several times.

Cheng Su's personal guards directly dismantled the multi-mounted machine guns on the power armor and erected them at the mouth of the tunnel, constantly shooting at Cheng Yanqiu and them, Cheng Yanqiu didn't know how many bullets Cheng Su's personal guards had fired and how many barrels had been scrapped in this short period of time, but the dense barrage had not stopped from the beginning to the present.

Bulletproof shields can indeed block large-caliber machine gun bullets, but in the face of a twenty-five-millimeter caliber cannon, even if one or two rounds cannot be penetrated, then what about one or two hundred rounds? What about one or two thousand rounds?

The pace of Cheng Yanqiu's attack suddenly slowed down here, if it weren't for the fact that Tunnel Zero was wide enough for the "Obsidian Type 2" power armor to drill into, with only the infantry, they would probably not be able to advance an inch.

The Obsidian Type 2 armor crossed its arms in front of it, bent its knees and slowly advanced, and on the front of the power armor, several heavy bulletproof shields were also hung, and the shells fired from the mouth of the tunnel continued to bombard the armor and shields, and the deafening explosion did not stop for almost a moment.

As for the others, they could only shrink behind the power armor, and no one dared to go head-to-head with 25 mm caliber cannon shells, not even the evolutionaries with heavy bulletproof shields.

"Keep going! Keep moving! ”

Originally, with the cannon on the shoulder of the power armor, it could also be used to fight back, but the firepower of Cheng Su's personal guard was too fierce, and it didn't take long for the cannon mounted on the power armor to be broken, and the guns in the hands of ordinary soldiers were not able to hit such a long distance, but in the face of the heavy fortifications built by the other party at the mouth of the tunnel, even if they hit, it had no effect.

Cheng Su's personal guards built a large number of fortifications in the space of a few hundred meters at the mouth of the tunnel, from the simplest sandbag stacks, to semi-permanent modular armor plates, concrete and cement poured bunkers, almost all the fortifications that can be built in a short period of time appeared in the tunnel, if it were not for such a passage, Cheng Yanqiu had no doubt that Cheng Su would directly send someone to completely seal the tunnel with concrete.

"It's only four hundred meters away from them, and you can attack with a bazooka!"

Finally, under the fierce firepower, Cheng Yanqiu and they entered the effective range of the bazooka, one by one the arms boxes were pried open, and the soldiers moved out of it a one-time pre-installed bazooka with a length of about one meter, this kind of bazooka is a copy of the AT4CS bazooka of the old era of the Mi Army, the biggest feature is that there is a big salt water bag hanging at the end of the bazooka where the tail flame is released.

CS here is the abbreviation of confined-space, which means "limited space", generally when the bazooka is launched, the rear 20 to 50 meters are in the danger range, if it is launched in a confined space indoors or in the vehicle, the tail flame that bounces back from the wall will burn the shooter himself.

However, the CS model bazooka is different, when launched, the liquid in the salt water bag can well neutralize the tail flame, it can be said that this special type of bazooka is specially designed for launching in a closed closed territory.

Dozens of soldiers rushed out with bazookas, and although several people were instantly knocked down by the bullets that came from the fire, there were still more than 20 rockets fired towards the position of Cheng Su's personal guards

"Boom!"

"Boom, boom!!"

The rocket hit the fortification directly in front of it, which immediately caused a violent explosion, and the soldiers who fired the bazooka immediately threw away the empty canister, pulled out the weapon behind their backs, and rushed forward!

"All-Army Assault !!"

At a distance of four hundred meters, it only takes more than a minute for these elite soldiers, and for the evolutionary, it only takes thirty seconds at most, and they can rush in front of those fortifications.

As the soldiers ran, they continued to throw grenades, smoke grenades, stun bombs and other throwing weapons behind the fortified bunkers, accompanied by a large number of explosions, smoke, noise and bright lights, and the intensity of the opponent's fire was instantly reduced.

"Kill it! These people are Cheng Su's henchmen, we don't need prisoners! Kill all the people who can move! Cheng Yanqiu ordered loudly, and he also raised a bulletproof shield and rushed forward behind the soldiers.

There is one last step, as long as you can break out of this tunnel, you can go straight to the Yellow Dragon! 2k reading web
