Of course, Liu Xing knows his current state, he can't use his shadow body technique with all his strength, and he has lost the blessing of the power of the sword, and his current strength is no different from that of an ordinary third-order evolutionary, if Liu Xing and Zhang Zhixue are allowed to fight again, Liu Xing will most likely lose to Zhang Zhixue.

"Don't talk about that, run!" Liu Xing said, bursting out with more evolutionary aura, blessed with the shadow body method, and ran towards the building where he was before.

After Liu Yuyi saw this, he didn't say much, so he had to continue to silently eliminate the zombies that appeared, and the three of them soon arrived at the bottom of the building where they were before.

To Liu Xing's surprise, the jeep parked at the bottom of the building before was actually nothing, and it was still parked on the side of the road as it was, Liu Xing hurriedly stepped forward to check the condition of the vehicle, fortunately the jeep was not damaged, otherwise he would have to find another car when he returned to Yanjiang City.

The three of them didn't stay too long, and hurriedly ran into the building, Liu Yuyi was just about to step into the corridor, but suddenly smelled a trace of gunpowder, Liu Xing hurriedly stopped in front of Liu Yuyi, and cautiously poked out his head to look.

The safety passage, which was originally very narrow, was full of zombie wreckage at this time, and the grenade traps that Liu Xing had ambushed in the corridor before had all triggered the explosion, presumably after Liu Xing and a few people left the building, a zombie rushed upstairs, causing the grenade trap to explode, which would lead to this scene.

"Liu Yuyi, you go ahead to investigate, be careful of zombies appearing!" Liu Xing turned his head and said to Liu Yuyi.

"Good! Let Li Dalong break off, you go safer in the middle! Liu Yuyi nodded to Li Dalong.

Although Li Dalong is a little silly, he can also understand Liu Yuyi's intentions, if Liu Xing is in the middle of the two, he can protect Liu Xing to the greatest extent, Li Dalong patted his chest and said with a loyal face: "Big brother, don't worry, I will definitely protect you!" ”

"You two ......" Liu Xing didn't feel that his self-esteem was hit, but he was a little moved, both of them were people he had just met, but they were still able to think about themselves so wholeheartedly, and it was really rare to meet such a sincere confidant during the end of the world.

"Stop grinding! If you want to say thank you, just get out of here! Liu Yuyi waved his hand and walked into the corridor.

Liu Xing didn't think much about it, after experiencing so many things with Liu Yuyi, the other party had already regarded himself as a true brother, but he always maintained a trace of defense, which really made Liu Xing ashamed of himself, didn't say anything more, and hurriedly followed Liu Yuyi's footsteps upstairs.

Sure enough, just as Liu Xing speculated, a large number of zombies gathered in the corridor, and there were a lot of zombies rushing out on each floor, fortunately, Liu Yuyi was prepared, and before the zombies poured out of the corridor door, he blasted out a lightning attack into the door, strangling the zombies in the door in advance, which did not let the zombies get close.

"If my guess is correct, the tide of corpses that gathered outside the Tianbo Enterprise Building before, in addition to dispersing to other blocks, more zombies still poured into all the surrounding buildings, and now most of the zombies near the military factory should be in the building!" Liu Xing analyzed.

"Zombie hordes didn't do this before, how can they spontaneously gather in the building now?" Liu Yuyi asked puzzledly, casually facing ahead

A lightning attack burst out from the door of the corridor, Liu Xing and Li Dalong followed Liu Yuyi's footsteps, and the three of them didn't dare to stop rashly, because there were still many zombies behind them.

"It's because of the relationship between the zombie territory!" Liu Xing said words that the two had never heard before.

"Zombie territory? What is this? Liu Yuyi didn't understand.

While climbing the stairs, Liu Xing took out the soaked cigarette case from his pocket, and after seeing that all the cigarettes were soaked, he reluctantly threw it on the corridor and said slowly: "Do you think how many third-order zombies were among them when the corpse tide gathered before?" ”

"Third-order zombies?" After thinking about it for a while, Liu Yuyi said, "I don't know this very well, but there are at least twenty or thirty third-order zombies I have encountered. ”

"Do you think third-order zombies are powerful?" Liu Xing asked again.

"I think it's rubbish, and I still can't withstand a lightning attack from me!" Liu Yuyi said with a pout.

Liu Xing's eyebrows were raised, and the corners of his mouth twitched slightly: "That's because you are too perverted, there was a corpse crisis in Yanjiang City two months ago, you know about it, right?" ”

"You know, it is said that 100,000 zombies poured into the city and led the troops of Yanjiang City to resist this corpse tide, aren't you the one who is the one?" Liu Yuyi said.

"I'm right, but you know what? The zombie that caused this zombie tide crisis is just an ordinary third-order zombie! Liu Xing said calmly.

"What! Third-Order Zombies! How is this possible? Liu Yuyi suddenly showed an expression of disbelief, and almost tripped over the corridor in surprise.

Liu Xing had long expected Liu Yuyi's reaction, and then said: "Zombies will begin to have spiritual intelligence from the second order, but when they really have the ability to think, they can only reach the third order, when the zombies reach the third order, in addition to being unable to speak, other actions and thinking abilities have reached the point where humans are at least ten years old, and they can also control other low-level zombies by releasing brain waves." ”

"Wang Jiale's previous special device to control the corpse tide was modified by the brain tissue of the fourth-order zombies, and he passed off his mind as the brain waves of the fourth-order zombies, so that all the low-level zombies could surrender, including the third-order zombies, which is why this corpse tide will happen suddenly!" Liu Xing breathed a sigh of relief and continued.

"What do you mean is that after the brainwave signal of the fourth-order zombies impersonated by Wang Jiale disappeared, the current corpse tide army was distributed by other third-order zombies, and each third-order zombie had its own unique zombie group, and let them enter the city's buildings separately, so these buildings with zombie groups are called zombie territories?" Liu Yuyi understood some situations from Liu Xing's words.

"Yes, that's it, you're smart, you can understand it all at once!" Liu Xing praised, and then turned his head to look at Li Dalong who was following closely behind, he still had a stupid expression, learning from the appearance of the agent he saw on TV, every few steps upstairs, he would look behind to see if there were any zombies.

"Won't third-order zombies be as congregated as other lower-order zombies?" Liu Yuyi continued to ask.

"As I said, third-order zombies already have human-like thoughts, and since humans will have desires, then third-order

Won't zombies give birth to territorial consciousness and establish themselves as kings? Liu Xing explained.

Liu Yuyi suddenly realized, and couldn't help but turn his head and say: "I finally understand, these third-order zombies were originally judged by strength, and they were distributed all over the city, and it is rare for two third-order zombies to exist in the same area, unless there are more powerful fourth-order zombies calling for them, it is impossible for these third-order zombies to get together!" ”

"That's right, this time the corpse tide army outside the military factory is controlled by Wang Jiale, who is pretending to be a fourth-order zombie, if I guess correctly, in order to leave you in the underground garage full of white smoke virus, he also deliberately gathered many third-order zombies there, am I right?" Liu Xing guessed.

"Yes, that's right, Chen Yang's team and I were ambushed by many third-order zombies, that's why we ......" What happened later, Liu Yuyi didn't say any more, thinking that Chen Yang's team was completely annihilated, Liu Yuyi couldn't help but clench his fists, eager to kill Wang Jiale again.

"Now Wang Jiale, who is pretending to be a fourth-order zombie, is dead, so these third-order zombies will not listen to anyone, and only gather the low-level zombies who originally belonged to their own camp, and each find a place to enter the nearby buildings, so that these high-rise buildings can become their habitat, instead of all zombies wandering around the city like a plate of scattered sand like in the early days of the apocalypse!" Liu Xing continued to explain.

"I didn't expect that zombies will also begin to develop a new social system like human civilization, if human beings really all die out one day, then the zombies who rule this earth, will it also be like the development of human social civilization, the first generation of zombie emperors will appear, and then the unconvinced zombies under their hands overthrow the dynasty, just like the feudal dynasty in ancient times, constantly changing dynasties, and eventually like reincarnation, zombies will be extinct by new species......" Liu Yuyi felt a little scary.

After listening to Liu Yuyi's conjecture, Liu Xing fell silent, in a sense, Liu Yuyi is not wrong at all, in the development of the zombie system in the next twenty years, the zombies have implemented a tribal system similar to that of ancient humans, each of them is a gang, and there is even a situation where some zombie tribes keep humans in captivity, which makes many humans with extreme personalities doubt in the future whether zombies are a new evolutionary system for human beings.

Human beings have gone through a long period of evolution from ape man, primitive man, sapien man to modern man, from the beginning to learn to walk upright, to be able to make simple stone tools, to learn to cook food with fire, until finally the germination of consciousness to produce language, and even the emergence of primitive religion, by the time of modern human beings, human beings have a mature language system and civilized society.

And the appearance of zombies, it is like the long evolutionary system of human beings, in another way, retold the general, the first-order zombies have just begun to appear ape humans, except for the basic eating nature, there is no other thought, when it comes to the second-order zombies, with the most basic learning ability, the third-order zombies begin to have the ability to think, and then evolve to a higher level, and when it comes to the last ten levels of zombie kings, the zombie kings at that time are no different from ordinary human categories.

Liu Xing suddenly recalled in his mind that in the late apocalypse of the previous life, the scene of the zombie king and the gluttonous tyrant having a dialogue and game on the battlefield...
