The female zombie who was kicked over quickly got up, and the kick that could temporarily incapacitate ordinary humans just now basically had no effect on her, and she still pounced with her teeth and claws.

"Fishy, you're far worse than my Sophia doll!" Zhao Yu kicked her again, and the sound caught the attention of the other three zombies, who began to gather towards Zhao Yu.

Zhao Yu took out an ordinary short sword from the bracelet, which was brought by the gladiator world, because there was plenty of space, Zhao Yu brought a few as consumables, which were just used to test the strength of zombies at this time.

The female zombie pounced again, Zhao Yu stabbed her in the abdomen with a sword, and pushed her to the ground again, this time it took a little effort for her to get up again, but there was no other major problem, it can be seen that the injury in the ordinary position is no longer fatal.

At this time, the fastest black zombie came behind Zhao Yu, Zhao Yu stabbed his chest with a backhand sword, pierced his sternum and pierced the heart, such an injury played a role, although the zombie was still struggling, but the strength and amplitude were getting smaller and smaller, as if the body was hollowed out, and the extremely thick blood flowed out of the wound, and the color was black.

Zhao Yu observed, and at the same time kept kicking the zombies that came over, the strength of these zombies has seven points, stronger than ordinary people, but compared to Zhao Yu, they are a scumbag, not to mention that they only have strength, but no speed and any skills, even if ordinary people want to defeat one, it is not difficult.

The black zombie who had been pierced through the heart struggled for three or four minutes, and finally lost his strength, and the blood flowed all over the ground, and this black and red blood had no attraction to their kind.

"Dead? It seems that the zombies in this world, the heart is still a fatal point, and the blood is still flowing in the body, which is essential for them, but the blood is a lot more viscous, so the flow rate is very slow, and it takes too long for the heart to die in such a position. Zhao Yu looked at the black man who fell to the ground and died, and analyzed.

"Next is the head, the lethal point common to all zombies." Zhao Yu cut off the head of an old zombie with a sword, and the zombie immediately fell to the ground and died, and the corpse was still pumping: "Cut off the head and die." ”

Then Zhao Yu smashed the head of a zombie with the hilt of his sword, and the zombie who was hit hard fell to the ground and got up again, his movements were very slow: "The brain is slightly damaged, the movement is affected, but it is not fatal, and the strength of the body is no different from that of ordinary people, and the brain is the same." ”

Looking at the zombie who got up again, Zhao Yu smashed him down with the hilt of his sword again, this time the zombie's movements were even slower, and they were crooked, and they couldn't control their body shape a little.

Then for the third time, the brains splashed out a little, and the zombie fell to the ground and died: "If the brain is seriously damaged, it will die, it seems that it can be killed in seconds with a firearm, which is a normal setting." ”

Killing a zombie with a sword again, there was only a female zombie left here who had been kicked down N times, Zhao Yu was surprised to find that the abdomen of the female zombie who was pierced actually stopped bleeding, and it was healing at an unimaginable speed for ordinary people!

Zhao Yu pressed down on the female zombie, stripped off her short skirt and underwear, and cut her shirt with a sword, you can see that the zombie's wound has grown granulations and began to intertwine, the black and red blood seems to be its excellent nutrients, the blood from the wound no longer flows out, but is absorbed, but in ten minutes, her wound recovered, leaving only a scar.

"Good breasts. Against the sky! The penetrating wound was actually healed so quickly, and there was very little blood flowing, but this zombie seemed to be a little sluggish, and it seemed to consume a lot! Zhao Yu was amazed, this special code is much more awesome than the zombies in the movie: "I'll take a look at it again, hey, the intestines inside have also healed!" Jinnyima is strong! The self-healing ability is strong, this is just an ordinary zombie, and the trait of mutated zombies may be even more terrifying! ”

Zhao Yu continued the experiment, he stabbed the female zombie again, this time he started the timer, and after twenty minutes, the wound healed again, except for some blood stains and scars, there was no problem!

The third time, it didn't heal for half an hour, it seems that this self-healing ability has a limit without external interference, Zhao Yu cut off her head with a sword, this poor female zombie who is naked, can finally get rid of the evil humans.

"I guess zombie cannibalism should be able to replenish their blood, and viscous blood is the backbone of their survival, and it may also be the key to evolutionary mutation!" Zhao Yu came to such a conclusion.

"These zombies are not really dead, according to the description of the challenge of the system, Dr. Osman seems to be able to invent something to save humans, and Sophia can also use this to restore herself to adulthood, they have just entered a magical state because of the virus, naked evolution and mutation, and they are still living beings!"

"But since it's a living thing, how can you survive five months without energy intake? Am I going to feed Sophia human flesh? ”

"And not all zombies can eat meat, will they die after a while?" Zhao Yu kept analyzing, he carefully looked at Sophia in the car, and found something he had just ignored.

Sophia has been tied to the bed for more than four days, but she is not hungry at all, and her skin is still as full as she remembers, which shows that the consumption of these four days is very little for her!

This doesn't make sense! There must be something else to replenish her consumption! You must know that Sophia often struggles, and it should consume a lot of energy.

"Well, I'm not a biologist, it's awesome to know so much, so I'd better leave this kind of question to Dr. Osman!" Zhao Yu gave up thinking, and with his non-biological knowledge, it would be good to be able to guess this step.

Testing these zombies, there was a delay of more than an hour, and it was almost noon at this time, in addition, Zhao Yu found that the time he entered was more than April, and the weather was quite comfortable.

Zhao Yu was about to go on the road again, but was stopped: "Hey! Zhao! This way! ”

The sound was very small, its owner was obviously lowering the volume, and it was also some distance from Zhao Yu, Zhao Yu looked up beside the car, and soon found the household diagonally opposite his house, and a piece of clothing stretched out from the second floor, still dancing.

Zhao Yu thought about it for a while, and the memory inserted by the system immediately surfaced, it turned out to be the little girl in the neighbor's house, a fourteen-year-old expired girl Lori who walked in the dark Gothic style, named Mary.

Mary's family were believers in God, but their daughter was rebellious and a 'believer in Satan'.

Of course, the little girl is not a bad person, but it is more in line with the trend of modern American youth, a little violent, and sometimes she will help Zhao Yu repair the lawn to make money, and she is usually very sensible.

"The main thing is to be beautiful, three years of blood to earn the death penalty is not a loss!" Zhao Yu recalled the little girl.
