The biological weapon like the Slayer A2 has a strong defense, and it is difficult for ordinary bullets to cause effective damage to it. However, the mecha is equipped with a bomb-piercing cannon. Even the biological weapon like the Slayer A2 will be smashed to pieces if it continues.

Although the firepower output of the Slayer A2 is very strong, the human killing machine mecha is vulnerable. The firepower of the mecha is more powerful than that of the Slayer A2. Even the first generation of mechas is not something that ordinary zombies can fight against.

The mecha continued to shoot at the front row of the corpse group, and the extremely defensive massacre A2 was so vulnerable in front of the mecha. With the mecha's participation in the war, the situation was also controlled. Everyone quickly filled the destroyed turret and built a circle of ground sting traps around the gathering place...

Although self-explosion zombies avoid the possibility of being detonated by high-voltage current by keeping a certain distance from ordinary zombies, ground stings are different. As long as self-explosion zombies pass through this place, they will definitely be pierced by the ground...

The length of the ground thorn is as long as 1 meter long, and it will definitely be awesome if you thorn it one after another.

"Lao Huan, something is wrong!" At this time, the Demon King discovered that the suppressed corpse group began to change its tactics. The evolutionary zombies in the corpse group began to catch the self-explosion zombies and threw them to the shelter...

"Boom!!!Boom!!!Boom!!!Boom!!!"

The self-explosion zombies hit the wall of the shelter like bombs and exploded. Although the walls of the level 5 shelter were already several centimeters thick steel plates, they had durability. Under such continuous bombing, the durability will be exhausted sooner or later...

"No! Something must be controlling the corpse group!" Luo Tianhuan realized that this was not the wisdom that zombies had. If every zombie evolved into wisdom, then every zombie should not cooperate so well, just like a professional army. You must know that even a group of humans would take a lot of time to train into a well-trained army, and these zombies naturally could not be trained.

This endless group of corpses is like dolls in the hands of a puppet master. There is an invisible line that controls each zombie to fight, and the controller behind the scene is very likely to be the mother of the virus...

But the problem Luo Tianhuan is facing now is that he doesn't know where the virus mother is...

"Huan...Brother Huan, the steel plate that sealed the elevator was knocked away, and a large number of zombies crawled out from below!" At this time, the team channel suddenly came the team member's report. Not long after the team member reported, the team member's death notice came...

"Ding! Team member Jian Yifeng is dead..."

"Damn it! Xiaofeng and Lao Zhao, you quickly rushed to the elevator entrance on the first floor and build a fort there immediately! Be sure to guard it for me!" Luo Tianhuan gave an order to the Demon King and Zhao Dexing. Luo Tianhuan knew very well that once the zombies were allowed to break through the shelter from the inside, everything would be irreversible...

When Luo Tianhuan commanded various departments to defend, the NPCs were huddled in the corner, and their weapons were all confiscated by Luo Tianhuan. It was the first time they had seen such a large corpse group, which made them fight with so many zombies. It would be good if they didn't get scared to pee their pants.

The endless corpse groups in the dark make people desperate, and what makes people even more desperate is that these zombies are like army. Not to mention that Luo Tianhuan has never seen such corpse groups, if Renault is here, he would probably have never seen him, a battle-hardened guy, or in Renault's eyes, zombies are just brainless things, and only the Zerg can be regarded as an army.

"Where is the virus mother?" Luo Tianhuan frowned. If the virus mother is not found, then the shelter will be trapped tonight...

Renault once told Luo Tianhuan that hesitation on the battlefield may cause his teammates and subordinates to pay the price of his life. Luo Tianhuan also made his own choice in those few seconds... He wanted to use the giant cannon...

Luo Tianhuan rushed downstairs quickly and headed to the control car parked at the entrance of the mall...

The battle situation was extremely fierce. Several self-explosion zombies fell near the control vehicle and exploded. Fortunately, the control vehicle had an outer layer of armor, otherwise it would have exploded into scrap iron like an ordinary vehicle...

"No matter where you hide... If I continue this shot, you will die!" Luo Tianhuan locked the bombardment range of the giant cannon directly in front of the mall. That position can hit the rear of the corpse group on a large scale, and it will not cause too much impact on the shelter...

"Look at my Italian cannon!" Luo Tianhuan pressed the launch button. At that moment, the dark sky in the entire Hailin City was cut by a ray of light... It seemed like a meteor, but only Luo Tianhuan knew that it was a cannonball...

"boom!!!!!"

The dazzling and strong light dispelled the darkness, and even the earth trembled. The deafening sound made everyone's eardrums hurt. The flames and light of the explosion swallowed up a large number of zombies. The glass was all broken in that moment, and the shock wave formed by the explosion had a considerable power. Even Luo Tianhuan's level 5 shelter was deducted by 100,000 durability because of the shock wave...

Everyone can imagine that if they face the shock wave without shelter, they might have only the result of the group destruction. It is not a nuclear bomb, nor does it have the terrifying power of a nuclear bomb that instantly destroys a city, but in terms of power, it can be called a small nuclear bomb.

Thousands of zombies were destroyed in that instant, including the mother of the virus hiding behind the corpse group and commanding and controlling the zombie army, which were completely destroyed under the giant cannon.

Giant guns are large and inconvenient to carry, and are usually installed on defensive fortresses or main ships, which is indeed powerful enough...

The mother of the virus was killed by a giant cannon, and the commander who lost the zombies completely became a mess. However, the embarrassing thing was that the giant cannon also directly scrapped most of the cannons, and everyone had to quickly rebuild the cannon for defense...

Fortunately, the mecha is not scrapped and can still be used, so it can continue to be used to output firepower to the corpse group...

"Rebuild the defense immediately! Xiaojie, cover the mecha! Xiaofeng and Lao Zhao clear the internal zombies!"

Luo Tianhuan issued an order. Although the virus mother has been killed, the danger still exists. Before the corpse group condenses again, defense must be established...

"I understand! Brother Huan!"

Everyone acted quickly, and this night caused heavy losses to the Sky Guild. This was also the only night that Luo Tianhuan suffered a great loss in so many days. The shelter was almost captured and lost a team member...
