The m1a3, which weighs dozens of tons, can rumble the ground and jump straight. When its car body appeared at the entrance and exit of the underground official residence, its muzzle had already been aimed at the fortifications of Marcos and others, and without hesitation, it bombed in.

The semi-enclosed entrance and exit passage doubled the sound of the shelling. Marco, who was hiding behind the fortification, was grinning in his arms, and when the cannon sounded, it felt that its armored pickup suddenly disappeared, and only felt that the fortifications in front of it were shocking.

The sound of the shelling was too loud, and the intelligent center of the power armor automatically cut off the volume input of the external pickup. This caused Marco to not hear the sound outside. The severe shock he felt was a grenade that exploded in front of the fortification.

The explosion of air waves blows Marcos, who has emerged from the fortifications, and it does not cause much damage to the fortifications. Because in order to leave a way out for himself, Zhou Qingfeng transports pieces of steel from the real world by heavy trucks.

Each heavy truck is equipped with solid steel ingots with a volume of one cubic meter and weighing more than a dozen tons. This solid steel ingot is thick and heavy, and several pieces are loaded side by side. Several such heavy trucks are blocked at the entrances and exits of the underground official residence. Not to mention that grenades cannot be blown up or armor-piercing bombs cannot be penetrated.

After a grenade, Marcos suffered the greatest damage that he was blown by the explosion. It got up in a panic and saw more than a dozen three-generation mutants rushing up quickly after the shelling. They thought that this gun must have severely damaged Marcos and his gang blocking the passage.

"Fuck these grandsons to death." Marco emerged from the fortifications, and the cannon in his hand sounded again. The thirty-mm projectile didn't care whether the mutants on the opposite side were one or three generations, and they all exploded into pieces.

The commando team of two squads died halfway through. Dania, who was commanding outside, screamed in anger, "Soon bombing the tank for me, drive in and bomb."

m1a3 completed the reload and bombed another round. As long as Comarco and others hid in the fortifications, there was nothing wrong. The only trouble was that the Incredible troops who entered the underground residence from other passages began to attack Marcos's lonely troops from behind.

"Go to ten people to clear out the enemies in the official residence. They have no heavy weapons and cannot stop our attacks. As for the tanks outside, it doesn't matter. Pull our heavy artillery up." With Marco's order, his mutants immediately began to act.

The weapons and equipment that Zhou Qingfeng got included an old Type 66 cannon. The cannon is a bit old, but it occupies a small area and is easy to fiddle with. The caliber of one or two millimeters is also powerful enough to get an advanced self-propelled cannon. The big guys of mutants cannot enter the cabin.

When m1a3 first appeared, it opened fire one or two hundred meters away from the entrance and exit passage. Marco didn't have time to use the cannon. But when the tank outside drove in again, it pushed the cannon out without hesitation, "Put the grenade and give the iron coffin a shot."

Boom..., shot out, but rushed in and opened fire first. The tank's captain became smart this time. He didn't know how Marcos' fortifications came from, but he knew that the ghost fortifications were particularly strong, and the grenades could not be blown up directly. So he rushed up and raised his muzzle and aimed at Marcos and others' heads.

The burst grenade hit the top of the entrance and exit passage at a very close range. The tank commander wanted to bury Marco and his group below by blasting the building structure at the top.

But when the grenade was shot out, it made a loud bang on Marcos' head. After a groove was blasted out, it did not explode. Instead, it ejected into the passage and hit a wall and became a dud.

The same result was the artillery of Marcos' team. It blasted out and hit the turret of m1a3. It flew away with a sound of duang and disappeared. There was no explosion. The two shells were both too close to each other. The projectiles were unloaded and the fuse was damaged before the projectile was released.

Marcos' armor had a head full of concrete slags. It shook its head and looked up. The m1a3 on the opposite side was nothing. It didn't understand why the shell didn't explode, but it knew that the m1a3 on the opposite side would take at least a few seconds to reload again.

"Give me the explosives." Marco shouted behind him.

The explosives were not taken up for a while, but a mutant responsible for operating the cannon stuffed Marco's launching medicine bags of several cannons. Marco jumped out of the fortification without saying a word, and the steel body, which was overly high in three meters, made a fearless laugh against the smoke of gunpowder.

Marco, who jumped out of the fortification, rushed to the muzzle of the enemy tank and quickly rushed over a distance of twenty or thirty meters. He piled several pieces of high-energy explosives on the front of the turret of m1a3, then turned around and ran back quickly. The whole process was full of rabbits and falcons, and m1a3 chased its back and blasted a grenade.

The explosion of air waves flew up Marco's explosion in the air, and more than two tons of power armor smashed heavily into the fortifications. Before it could get up, it shouted: "Bang the pile of launching medicine bags."

The second shell of the Mutant Guard was also ready. This time the gunner changed into a special shrapnel and blasted it out. The shrapnel could not blow away the armor of m1a3, but the scorching high-speed projectiles were overwhelming. The high heat generated by friction easily detonated the launching medicine packs piled on m1a3.

A violent explosion sounded again on the battlefield of this passage. Dania outside the passage was commanding the battle in a building a hundred meters away. When the explosion occurred, the glass of the building broke all at once, and the sound of vibrating the air exploded in everyone's ears.

Dania felt like someone threw a shock bomb in his ear, and the sound was so loud that it was extremely painful. Ordinary people who had not been strengthened were shocked by the loud noise. Dania himself felt his chest tightness and his ears buzzed.

"Do you kill that group of ugly monsters?" Dania finally recovered. She thought it was an explosion created by her side. But after asking, she learned that the tanks she sent were killed. Marcos and his gang, who were blocking the entrance and exit of the underground official residence, were still resisting.

"Assistant Dania, our tanks were blown up in the passage, and our people were blocked outside, so it was difficult to attack."

"Ms. Assistant, the fortifications of that group of mutants are too strong to explode even if they explode."

"The poison gas is useless, they are wearing heavy power armor and must have air filtering devices and spare gas cylinders. They are so well prepared."

After using many methods, Dania, who was in charge of command, couldn't handle Marcos and his group. Just as she wanted to fill gasoline into the passage, an Incredible officer suddenly ran to her and whispered a few times. After hearing this, she frowned and asked strangely: "How is this possible?"

The officer who came was Dania who used his power to lie in the senior management of Incree. The other party told her that a mutant suddenly appeared and a large number of solid fortifications had extremely mysterious and incomprehensible ways of appearing.

"The entire surveillance video of the official residence has a backup surveillance point. Now our two-headed President Lawrence already knows this. But they decided to keep it confidential and are just urging us to kill Victor Hugo who is coming to the door immediately."

The officer who came to report the news explained the origin of the news and whispered, "We might as well slow down. Now it seems that Victor Hugo has a more promising future. Maybe we should join him. Discuss with that group of mutants, how?"

Dania's eyes rolled and her mind began to think wildly. Instead of thinking from a long-term perspective, she had a bolder and more utilitarian idea, "Call a team of engineers to arrange explosives, blow up from the surface and blow up the entire underground residence and the affiliated command center."

"Blast?" The officer reported the news and was unknown.

"Yes!" Dania yelled viciously, "I'm so stupid. I didn't even think of such a good opportunity at the moment. Why didn't I blow Victor Hugo and 'David Lawrence' all underground? They died together, and the world is ours."
