After three days, Tao Fei was crazily killing more than a thousand zombies. There were mutated ones, but they were not very powerful zombies, but basically 99% were ordinary zombies.

The crystals in his hand were enough for him to use them from morning to night. Before going to bed, he would put the largest crystal in the palm of his hand to absorb them.

However, the ability improvement has become slower and slower. The lowest-level crystal of ordinary zombies has had little effect on him, but the more advanced crystals are extremely rare.

Tao Fei thought about letting Lan Xiaoting absorb some crystal energy, but he didn't know what the result would be after absorbing the crystal energy. It would be fine if it was a good direction, but if it was a bad direction, he would regret it to death.

What he wants to do now is to find some other human survivors and use them to do experiments. There are the same survivors in the upper level opposite, and Tao Fei knew that, but the survivors there had also reached the most critical moment, because someone else could not help but rush out again.

Looking at the window opposite, several survivors shook the signal of help at him. Tao Fei closed his eyes tightly. He had no choice but to rush over, but after rushing over, maybe he couldn't rush back. There were thousands of zombies outside, and the army attracted too many zombies, but they left.

Tao Fei has grenades, but after throwing the grenades, it will make a louder sound, which will only attract more zombies to come here.

In the morning, Tao Fei wore his special equipment, a piece of equipment covered with zombies and carrion. In this way, killing zombies outside would not attract zombies from farther places.

Tao Fei's movements were very fast, and the zombies rushing towards him were easily killed by him. At this moment, the rumbling sound from a few days ago came again. Tao Fei was stunned and the guys came again in the tank.

Thousands of zombies on the square were killed by hundreds of troops one by one. The killing was very fast. They rushed into the underground supermarket again for crazy plunder. Tao Fei quickly returned to his room and protected Lan Xiaoting, but used a reflective mirror to secretly check the scenes outside.

The army's actions were even faster this time, and they did not come to take revenge on Tao Fei. They seemed to be in a hurry. This time, a total of thirteen large trucks were dispatched, which was a large army of 300 people. In this chaotic environment, the army's survival ability was definitely the strongest. They had weapons, organized, and were far away from the downtown area.

Seeing the large number of things in the supermarket moving to the truck, Tao Fei felt distressed. These are the capitals for survival! The army came and left quickly. In just one hour, the army retreated and left behind zombies all over the ground, which made Tao Fei much more convenient.

Taking advantage of this space, Tao Fei rushed out quickly and quickly collected the crystals of zombies on the ground.

Just as Tao Fei lowered his head slightly, a bullet passed by his head against his scalp. Tao Fei was shocked. He knew that it was the army that the sniper wanted to kill him and avenge their comrades, and he unconsciously bowed his head and avoided the fate of death.

Tao Fei, who knew his situation, ran towards the same path, constantly changing directions, and rushed into the unit door in an instant. This speed surprised the warrior who ambushed him. The speed of the 100-meter athlete was not as fast as Tao Fei. It took only four or five seconds for a distance of 100 meters. Is the human potential really so great? The ambush thought about it in a little puzzled manner.

However, Tao Fei had already entered the unit door, so his ambush failed, so Shi Shiran walked out of the dark corner of the ambush and ran along the road driven by the tank.

Tao Fei cursed in his heart: "No wonder it was cleaned so clean this time. It was cleaned so clean when he went back. His feelings were to get caught!"

But no matter how much I think about it, Tao Fei still has to collect crystals, otherwise he will be in trouble again if other zombies arrive.

For some reason, if the zombie dies for more than a certain period of time, there will definitely be no crystal in the head. Tao Fei deeply understands this. Because he was too tired when he was cleaning the stairs passage, he took a break. When he went there the next day, he didn't collect a single crystal, which made him very depressed.

In order to verify whether the crystal will disappear in the zombie, Tao Fei used two methods. One is to put the crystal into the head of the dead zombie, and the other is to find a zombie with crystal in the dead head. It turned out that the crystal would disappear two hours after the zombie died, so Tao Fei dared not waste time.

However, Tao Fei is already too familiar with zombies. Maybe he may not know which zombie has no crystals in its head, but he knows which zombie has no crystals in its head.

Therefore, the first choice for collection is naturally the zombies that look more powerful, so you will gain more.

After the zombies outside were cleaned up, more than a dozen survivors rushed out from the three high-level officials one after another. Looking at their shaking appearance, they knew that they must have lived a miserable life. No one paid attention to Tao Fei's every move. They rushed into the underground supermarket at the first time, and they needed survival supplies.

Seeing that there was no crystal found in the heads of several zombies who were bound to have crystallization, Tao Fei knew that his harvest today had ended here.

However, none of the people who rushed into the underground supermarket came out, which made Tao Fei a little strange. At this time, there were relatively few zombies from afar. Tao Fei's depth space was still very large, but the first thing he had to do now was to transfer from this high-rise to another high-rise, because the elevators and stair passages on this high-rise were already messy. Such an environment was most likely to attract the attention of special mutant zombies, and some corruption-eating creatures. The terrifying level of these corrupted creatures is no less than that of special mutant zombies.

He rushed back to his room quickly, cleaned up the dirty things on his body, quickly changed his clean clothes and tied Lan Xiaoting to his back, picked up the packaged food and tied it in front of him, and slid to the first floor along the steel rope of the elevator.

The appearance of two clean people attracted the attention of the zombies who had just come over around him, but Tao Fei was very fast and rushed towards an open unit door. The speed was extremely fast. Before the zombies could come, he had already rushed in. This unit door was left by a survivor when he came out. Extreme hunger made the survivor forget this crucial thing. Once the zombie entered the unit, the only thing waiting for him was death.
