Seeing that Wei Fan's knife was about to slash the corpse king's head, the corpse king suddenly stretched out his arm to block his head. With the corpse king's roar, Wei Fan cut off the corpse king's arm.

The roar of the corpse king also brought back the level 4 zombie that was entangled with Genwang Han and others. At the same time, the giant zombie beside the corpse king also reached out to suffocate Wei Fan.

Wei Fan easily avoided the attack of the giant zombies and opened the distance from the corpse king. Looking at the layers of protection around the corpse king, Wei Fan knew that it was impossible to kill the corpse king.

Even the corpse king was unable to kill the corpse king under unexpected circumstances. Now the corpse king is obviously prepared and the same method can no longer be used for the second time.

"Retreat!!" Wei Fan shouted unwillingly, and he dodged a few times before returning to the car. When Wang Han saw Wei Fan coming back, he kicked the accelerator and rushed out of the corpse group.

Wei Fan was in a bad mood at this time, but he didn't seize such a once-in-a-lifetime opportunity. It would not be so easy to attack the Corpse King next time.

Therefore, the zombies along the way became Wei Fan's punching bag. Under the various bombings, the off-road vehicles quickly emerged from the crowd of corpses and headed towards the base.

At this time, the soldiers who were standing on the second line of defense saw Wei Fan retreating and began to withdraw the base as ordered. Wei Fan's plan to block the zombies with two lines of defense also failed.

Although the explosives placed in advance were still blocking the corpse's pace, it was only a matter of time before we could reach the base.

On the way back, the entire team was filled with a dull aura, although there were no casualties in this operation.

Wei Fan sat in the car without saying a word. He was a little taken for granted. Not only did he underestimate the corpse king's ability, but he also did not calculate the power of the thermal weapon in the end of the world.

The only thing you can do now is retreat to the base and fight to the death with the Corpse King at the base.

Wei Fan simply closed his eyes and rested in the car. The previous series of killings made Wei Fan's body a little overwhelmed. He took the opportunity to take a good rest to deal with the next battle.

The team retreated to the base in an orderly and quickly, and at the same time, a series of explosions behind them also reminded people that the crisis had not been resolved.

Soon the city wall of the base was already far away, and most of the survivors of the base were digging holes according to Wei Fan's request. Wei Fan immediately ordered the stop of digging holes and let all the survivors be pulled into the base.

At the beginning, Wei Fan planned to use this pit to bury all the zombies in Pingsha City, but with the existence of the corpse king, all plans were stranded.

As soon as he returned to the base, Wei Fan rushed to the research institute without stopping. Now he was eager to know whether Zou Ming's research was successful. This might be the last chance.

When he came to the research institute, Wei Fan directly found Zou Ming and began to ask about his research results. "Have Zou Ming developed his research? The zombies are about to come to the city."

"It has been studied, but the power has not been tested and the level one uncertainty has not been solved yet." Zou Ming took out a pistol-shaped weapon.

I saw that the weapon was pitch black all over, larger than a pistol, and the muzzle was particularly thick, so it was more suitable to call it a hand cannon.

"I call this weapon an energy gun. It needs to be filled with evolution beads as energy supply, which can adjust the power of the output energy. The greater the power, the higher the level of the evolution bead, and the longer the accumulation time." Zou Ming introduced to Wei Fan.

"Currently, the level 3 evolutionary beads can be filled in at level 4, but there are many unstable factors."

Wei Fan looked at the energy gun in his hand and couldn't say whether it was a joy or a sadness. It was true that the energy gun designed by Zou Ming had power, but the defects were also obvious.

"I took this one away. You should hurry up and study it. Try to shorten the accumulation time and solve the unstable factors of using high-level evolution beads as soon as possible."

As he said that, Wei Fan left the institute. Faced with the soon-to-be-arrival zombie siege Wei Fan still had a lot of things to arrange. This time, he was not as failed as before and could retreat, and he had no place to retreat.

When Wei Fan came out of the institute, he found that there was no one in the bounty hall at this time, so Wei Fan hurried to the city wall.

At this time, the city walls were full of people, soldiers, evolvers, and ordinary survivors. Everyone was holding weapons in their hands and waiting for the battle.

Wei Fan found Mr. Hua in the crowd. When Wei Fan walked over, he found Mr. Hua was comforting the ordinary survivors on the city wall.

Seeing Wei Fan coming, Hua Lao hurriedly greeted him, "Xiao Fan, please help me persuade these people. They didn't listen to anything I said, and they insisted on staying to help us guard the base."

Wei Fan gave Mr. Hua a look of peace of mind and stood up and said loudly.

"Everyone listen to me quietly. I know everyone's mood at this moment, and I am very grateful to everyone for having this heart, but the walls are too dangerous for you.

Zombies can be attacked at any time. The purpose of establishing the base was to give everyone a foothold in the end of the world. Now, although the base is at the critical moment of life and death.

But please believe me. If you want to do your best, stay in the base and stay away from the city walls. This is the greatest help to guard the base. Now all the evolvers and ordinary survivors who are less than level 2 have retreated to the base and cannot come out without orders."

After saying that, Wei Fan directly asked the soldiers to forcefully drive these survivors down despite the opposition of some people. It is a good thing to have this intention, at least it means that they have regarded the base as their home, but these people will not have any effect when they come up, but they will have to distribute troops to take care of them, which is not worth the loss.

At this time, a scene of rushing on the city wall was constantly being placed on the city wall, with various light and heavy sniper rifles, large-caliber machine guns, machine guns, and some weapons 66 that Wei Fan had never seen before were continuously placed on the city wall.

In order to deal with this zombie siege, the military region took out all the inventory. Even if these things are kept when the zombie level is high, they will not have much effect. It is better to use them this time. Anyway, killing zombies is not a waste.

Speaking of inventory, Wei Fan remembered something indifferent, that is, the failure of electronic instruments has caused all fighter jets in the military region to be useless, and some old-fashioned fighter jets have long been eliminated, and the military region has not, so Wei Fan's idea of ​​air strike against the corpse king cannot be implemented.

Wei Fan’s only hope now is to try to level 4 before the city breaks. Although the energy gun developed by Zou Ming has a certain chance to kill the corpse king, Wei Fan does not want to place all his hopes on the energy gun.

The previous sneak attack had already made the Corpse King alert, so Wei Fan would no longer take action rashly if he failed to kill with one blow.

Night falls quietly.

After a whole afternoon of busyness, under the dual pressure of physiological and psychological pressure, the soldiers began to become tired and exhausted. Therefore, Wei Fan ordered the soldiers to rest in batches while he himself stared at the front without blinking.

Wei Fan tried his best to pray that the corpse group would arrive after dawn, because it was much more difficult to guard the city at night than during the day. On the one hand, the vision was very serious, which was the bonus for the corpse group at night.

However, the heaven obviously did not stand on Wei Fan's side. Soon Wei Fan heard the roar of the corpse group. Dozens of searchlights were turned on at the same time, and the entire city wall was like daylight, and the corpse group was completely displayed in front of the base.
