There was no movement in the room, so Chu Bai jumped off the fence and prepared to open the door and go in to have a look. He came to the door lightly, and the door was an iron door with a key inserted on it, saving Chu Bai from violently destroying it. With his ears on the door and listening to the sound in the house, he didn't find anything abnormal, Chu Bai turned the key and opened the door.

"Not good!" As soon as the door opened a crack, Chu Bai smelled a trace of foul smell between his nose, which was not the familiar corpse smell, but the smell of feces and urine. Chu Bai frowned, his body tensed and suddenly became alert, and with a fierce force, he was about to push the half-open iron door back and close it again.

Just as the iron door was about to close, a huge force suddenly slammed into the door from the room, and the force was so great that Chu Bai took a step back, and then a big claw full of black hair stretched out from the crack in the door, followed by a sharp mouth with bared teeth. There was also a whirring low roar from the sharp mouth, and Chu Bai could smell the stench coming from his mouth.

Chu Bai wanted to increase his strength to close the door, but the unprepared bump just now made him lose the opportunity, but instead let the monster in the room take advantage of the situation and squeeze out half of his body, and the monster turned around and bit Chu Bai by squeezing out half of his body outside the door. Seeing the whitening fangs getting closer and closer, Chu Bai gave up the idea of closing the door, landed steadily with a backward jump, and then retreated against the courtyard wall one after another, put the backpack on his chest, raised the pistol in his left hand, and held the axe in his right hand and hid it behind his back, staring closely at the monster at the door.

Chu Bai fled for a moment, and the monster immediately rushed out, with so much strength, that it slammed the iron door into the outer wall with a loud bang. I saw a black-faced fanged dog with long black curly hair standing majestically at the door, it first shook its body and shook its hair, and then looked up at Chu Bai in the courtyard, and its eyes full of red light revealed cunning and ferocity. The black dog weighed seventy or eighty pounds, and its black hair was shiny in the sun, revealing a chill all over its body.

"What a big black dog! With this size, this strength, and this momentum, it seems to be an evolutionary beast. Chu Bai was stared at by the black dog, and he didn't dare to make more movements, but he raised the gun in his left hand and aimed at the black dog, and the axe in his right hand was held tighter and ready to slash forward at any time.

At the moment when Chu Bai's muzzle was aimed at the black dog, the black dog's body shook, as if he felt threatened, and he actually walked around uneasily and began to dodge the muzzle. The black dog dodged left and right, and Chu Bai's muzzle also followed, the two were already close, the muzzle was always locked on the black dog, and at the same time, he also paid attention to his own position, and always hid his right hand with the axe behind the black dog's invisible.

Seeing that he couldn't avoid the muzzle, the black dog simply didn't dodge, and the light in his eyes was even better, revealing Bai Sensen's sharp teeth, and he roared and pressed his body backwards, looking like he was about to pounce.

Chu Bai was also extremely nervous at the moment, after all, this was the first time in his life that he had met an opponent of equal strength. The black dog is actually an evolutionary creature like Chu Bai. The creatures of the earth are affected by the black fog, and some individuals in the animals will also mutate, but they do not become zombies, but evolve, forming an existence similar to that of evolved people. And this black dog is the guy who has successfully mutated, theoretically speaking, it and Chu Bai are both in the stage of first-level evolution, so whether it is the black dog or Chu Bai, they both feel the strong pressure on each other, which forms a confrontation situation.

However, the beast is still a beast, and the black dog finally couldn't resist the temptation, and his body rushed towards Chu Bai like a black light. It was vaguely aware that it would be good for itself to eat the flesh and blood of the humans in front of it, and even if the other party had a strong sense of threat, it still chose to attack.

Seeing that the black dog pounced, Chu Bai shot it directly, he didn't care if the sound of the gun would attract a group of corpses, he just wanted to kill the mutant dog in front of him now. For the black dog, Chu Bai's flesh and blood is a great tonic for evolution, and vice versa. The black dog is also a great temptation for Chu Bai, to be precise, the crystal nucleus in the black dog's brain is a great temptation. As a first-level evolution beast, the white crystal nucleus in the black dog's brain had a hundred units of energy, and Chu Bai naturally didn't want to let go of this opportunity.

"Bang Bang Bang"

Chu Bai fired three shots in a row, and three earth flowers splashed on the ground, but the black dog was not injured, and the bullet did not hit it at all. Although the black dog took the risk of pounced on Chu Bai, it was not stupid, feeling the threat of Chu Bai's pistol, the black dog only rushed forward for a short distance and immediately changed direction and turned to one side, the speed did not decrease, and it flew towards Chu Bai, opening a dog's mouth in mid-air.

Chu Bai unexpectedly fired three shots in a row to no avail, he didn't expect that this black-haired beast still knew how to feint, and after three shots, the black dog was already close in front of him. Although the black dog in mid-air was a good target, Chu Bai didn't have time to aim and shoot anymore, and subconsciously waved his right hand violently, and the powerful axe slashed at the black dog's head.

"Woo woo" The black dog writhed in the air, and the dog's head narrowly avoided the slash, but one of its front legs was cut off by Chu Bai's axe, and blood was sprinkled from the air.

The injured black dog was even more ferocious, and threw himself into Chu Bai's arms at the cost of a broken leg, pressed Chu Bai to the ground, and then opened his mouth to bite Chu Bai's throat.

Behind Chu Bai was a wall, his body was against the wall, and he was hit head-on by a black dog and knocked to the side. Originally, the black dog was aiming at Chu Bai's neck and pounced, but unfortunately he was cut by an axe in the air, and his body sank a little, and Chu Bai was on the side of the fall, so the angle of the attack was wrong. The wide open dog mouth did not bite Chu Bai's throat, but bit it into his chest, biting on the backpack on Chu Bai's chest.

Although he was not bitten by the black dog, the impact still made his chest uncomfortable. Taking advantage of the dog's mouth biting into the backpack, Chu Bai withdrew his hands and pushed the black dog's body to the left side, trying to push the black dog away.

The black dog who wanted to let go and bite again felt the huge push to the side suddenly, and he didn't dare to let go of his mouth at all, if he let go of his mouth and was pushed away by Chu Bai, it would be difficult for the black dog with a broken leg to get close to Chu Bai, and he would definitely be killed by Chu Bai flying a kite. The thrust disappeared, and although the black dog's body left Chu Bai's body, the dog's head was still hanging in Chu Bai's arms. Taking advantage of the moment when Chu Bai's strength was exhausted, the black dog let go and bit Chu Bai's throat again.

With a "dang" sound, the black dog felt that his teeth were about to collapse, and he did not have the refreshing touch of biting into the flesh as he imagined, and what he felt in his mouth was a cylindrical hard object.

The thing stuck in the black dog's mouth was Chu Bai's just-handled axe, which was originally to push the black dog to the left with the axe, and after pushing the axe, the direction of the right hand just stopped in front of the chest, at this time the black dog opened his mouth and bit it, and Chu Bai easily stuck the axe handle into the black dog's mouth.

The bite was blocked again and again, the black dog was ferocious, exerted all his strength, bit the axe and tore it desperately, and shook the dog's head wildly, the strength was so great that Chu Bai, who was lying on the ground, was not good at exerting his strength, and he couldn't resist it for a while, and the axe was thrown away by the black dog.

After throwing off the axe, the black dog was overjoyed, looking at the white and tender neck under him, like a plucked chicken, the dog's mouth was salivating, and he squinted his eyes comfortably, and hurriedly opened his mouth to bite his throat, this time he said that he would bite half a catty of meat.

With a "dang" sound, the black dog was about to burst its teeth again, and another cylindrical hard object was inserted into the dog's mouth. The black dog was suddenly furious, and looked in front of him with an unprecedented sense of humiliation, only to see the human in front of him with an evil expression. The black dog's gaze shifted to what was in his mouth, and a chill swept over his body, and his eyes were terrified.

"Bang bang bang" Chu Bai fired three shots in a row, pushed away the dead dog on his body, and blew the barrel of the gun while sitting against the wall. Looking at the dead dog on the ground, Chu Bai was very happy, and finally harvested the first crystal nucleus.

After the death of the mutant dog, Chu Bai did not absorb any energy, because the evolved creatures would form crystal nuclei in the brain, and all the energy would be gathered in the crystal nucleus, and would not escape from the body like zombies. If the zombie absorbs enough energy, it will also evolve to produce crystal nuclei.

After the fierce battle, Chu Bai felt very tired and hungry, so he rested and ate on the spot to replenish his mental and physical strength.

"After all, it's an evolution beast, so it's really hard to deal with. Just now if one is not careful, he will die, but this is the end of the world, and I can die at any time, unless I become strong enough. After a fierce battle, Chu Bai became even more determined to enter the park to find the treasure chest.

Chu Bai is now just an ordinary first-level evolutionary person, and it is already very good to single-handedly kill an evolutionary beast with the fighting will and skills of his previous life. You must know that generally speaking, evolutionary beasts of the same level are more powerful than ordinary evolutionary people, but only ordinary evolutionary people. Humans can open treasure chests to strengthen their strength, get high-level weapons and magical abilities from treasure chests, and even become powerful professionals, which is the capital that humans can fight against mutant beasts and bugs in the last days.
