Evolutionary zombies kept pouring out of the passage, and all eight passages were opened. Even if four people defended one passage, it was still very difficult. Everyone had to hold on for 10 minutes in this situation, but now 7 minutes had passed.

An evolutionary zombie with a red body crawled rapidly on the wall like a gecko, and this evolutionary zombie has a strong tail, which is the most powerful weapon of the evolutionary zombie. The evolutionary zombie is very fast, reaching a level that is difficult to capture with the naked eye.

A long tail wrapped around the neck of an Immortal member and threw it into the attacking corpse group, which instantly swallowed up by the evolved zombie group.

A channel began to fall, and then all channels were lost. Everyone retreated under the control platform in the center of the experimental field to resist the continuous attack of the evolutionary zombies.

"How long will it take? A stinky woman!"

"It's almost there! 2 minutes left!"

"What? There are 2 minutes left! Damn it! Everyone has guarded me!" Victor shouted, his hands mutated, and kept slaughtering the corpse groups that were coming.

The corpse group surrounded everyone, and everyone took out melee weapons and fought close to the evolutionary zombies. If it were ordinary teams surrounded by these evolutionary zombies, they had long been wiped out. However, the Dark Vortex Army and the Immortal Bird Team actually competed with the evolutionary zombies.

The rotten blood was poured on Luo Tianhuan, and the evolutionary zombies kept biting the armor on everyone's body. Although the armor on everyone's body had the function of self-healing, it couldn't last long.

The corpses of the evolutionary zombies had already piled up a wall in front of everyone, but the evolutionary zombies were still rushing towards everyone. As the space became smaller and smaller, everyone was about to be swallowed up by the corpse group.

"Ho huh huh!!!"

An evolutionary zombie threw a member of the Dark Vortex to the ground, and then all the evolutionary zombies behind pounced on the member and started biting them wildly.

"Get out!"

Luo Tianhuan waved his laser swords and killed all the evolutionary zombies on the team member, quickly pulling him out of the zombie corpse.

"Thanks!"

"Now is not the time to say thank you!" Luo Tianhuan stepped on an evolutionary zombie, and then stabbed the evolutionary zombie in the head with a sword.

The armor on everyone's body can effectively defend against zombies, otherwise everyone would have been infected with the GRT virus long ago.

"Okay! Come up quickly!"

"clear!"

Everyone released the laser cable on the armor and jumped onto the platform where Anna was located through the laser cable. However, the evolutionary zombies below did not intend to let everyone go. Some evolutionary zombies began to spray some corrosive liquid at everyone, and some evolutionary zombies even threw their limbs at everyone, and those limbs exploded like flesh and blood bombs.

Everyone turned on the energy defense shield to resist the long-range attacks of those evolutionary zombies. Although the platform is very high, some evolutionary zombies with extremely strong climbing abilities can still come to the platform where everyone is, so everyone must leave here as soon as possible.

"boom!!!"

At this time, a loud bang came, and everyone saw a large amount of black mud pouring into the passage, swallowing all the zombies along the way, while the other passage had begun to collapse. During the collapse, Victor could see the dancing tentacle.

"Tiamat!"

The tentacle was one of the tentacles on Tiamat's body. The virus black mud and Tiamat attacked everyone on both sides, and the evolutionary zombies below seemed to be in a catastrophe. Either they became a pile of meat paste under Tiamat's touch, or they were swallowed up by the black mud.

"Fast-for-port portal!"

A not-so-large space channel appeared on the platform. Although it was not big, it was enough for everyone to enter. Everyone rushed into the portal. In less than 5 seconds, everyone had evacuated. At the moment everyone was evacuating, Tiamat's tentacles swept past and hit the platform. A series of sparks burst out of the entire platform, collapsed from the air, and the portal disappeared...

...

"Huh! I've really escaped from death this time!" Looking at the space portal that disappeared behind me, Anna still looked lingering fear, and they almost couldn't come back.

No one can guarantee that he can survive in front of the Black Mud and Natiamat. Even the Dark Vortex Army and the Immortal Bird Squad cannot. If Anna opened the portal later just now, or if everyone entered the portal slowly, it would be a group of destruction.

"The day I'm with you is really more exciting than what I've experienced in my life. This is definitely the most exciting day in my life." Anna wiped the sweat from her forehead. Now they are 800 meters underground, and there is a last step away from the ground. Although it is also the occupied city occupied by zombies outside, compared with the inside of the base, the outside is simply a paradise!

During the 10-minute battle in the experimental field No. 18, everyone was nervous to fight. In this battle, 5 people were sacrificed by the Dark Vortex team and 6 people were sacrificed by the Immortal Squad. It can be said that until now, both the Dark Vortex team and the Immortal Squad have lost more than half of the personnel. This time, they entered the A-project base to eliminate Tiamat, and they were not only defeated, but also completely.

Although everyone was very tired after those 10 minutes of high-intensity battles, everyone had no chance to rest now. Tiamat would soon reach the depth where everyone was now, and they had to evacuate as soon as possible.

"Next we go to the base's equipment and ammunition depot, which is closest to our current location. Through the portal there and through the identity verification, we can see that we are transported to the base's logistics food storage area. Finally, we can leave smoothly through the transportation train there!" Anna looked at the comprehensive map of the base projected on the communicator and said, now it is not much time to leave the base.

"Okay! Everyone set out!"

Without wasting too much time, everyone quickly set off...

"Ding! Alarm! Tiamat has broken through the restricted area, the base's self-destruction system has been started, the base will self-destruct itself in 10 minutes. Please evacuate personnel from various departments quickly!"

"What's going on? Where is the restricted area in Tiamat?"

"1,000 meters underground!"
Chapter completed!
