In the middle of Europe, a chaotic area comparable to the forbidden area of the Chinese country - the rat city.

Fifty years ago, the second mutant plague broke out, a variant of the virus that was even more terrifying than the Black Death in the Middle Ages, evolving to spread through the air, infecting entire towns without the first antibodies being produced. In the end, the country had to use nuclear weapons to clear the interior, while building a 100-meter-high military wall to completely isolate the interior.

The revenant souls and some of the extraordinary humans continue to survive in the rat city, and in the life without the dawn, most of the people have changed their bodies, and their hearts have become more sinister than the darkness. With the passage of time, Rat City slowly developed a mixed class constitution and management constitution.

Rat City, one of the darkest regions in Europe.

During the summer vacation, a duel is being held in the deepest part of the famous spiral prison pit in the human living area of Rat City, and any extraordinary people or ghosts who exceed the human physique are not allowed to participate in it, and the humans participating in the battle must also have a residence permit in Rat City, and outsiders cannot mix in it.

The final reward for the duel was that the year before last, only one-third of the capable people in Rat City had exchanged death for a "rare" core.

The purpose is to cultivate the strong men in the Rat City, and one day they will be able to cultivate strong enough strength to launch an uprising and break through the restrictions.

The battle has now entered the final round, and the host, who is dripping with pus all over his body, announces the entry of the two human contestants who have entered the finals.

On the left is a small, cloaked human, who is very short compared to the ugly and tall spectators on the surrounding stage, and the audience erupts in loud cheers as he appears.

The first few players who underestimated this person were all cut off in a few seconds, and the human under the cloak was very good at assassination.

Immediately afterward, another human player entered. Out of the passage on the right was an ordinary man with plenty of hair, 1.75 meters tall, whose most prominent feature was a rat's tail.

Among the plague coexistences, more than 1,000 of the tens of millions of people in the rat city did not die, but only no more than 10 people not only did not die, but also let the body cells combine with the plague virus and mutate into a very strong body.

"Cicero, son of the Rat King."

This ratified male has long been famous in the Rat City, this person is the youngest son of the first Rat King, maintaining the human state, receiving instructions from his father to come to the arena to become the king of dueling, ready to use the "rare" core obtained to break through the human limit, so as to gain more favor from his father among many brothers.

"Don't cowards hiding under cloaks even dare to show their faces?"

The short, thin human under the cloak didn't talk nonsense to Cicero at all, and left a few afterimages in place by moving at high speed, his left hand on Cicero's shoulder, turning his body around the opponent's back, and the dagger held in his right hand was wiped towards his neck.

"Do you think I'm still a pawn from before?"

Cicero the nezumi opened his mouse-like teeth and bit the severed dagger to pieces.

At the same time, he uses the extremely sensitive and tough rat tail behind him to wrap around the opponent under the cloak.

"Huh!"

The cloak that obscured the body was wrapped in the rat's tail, but the humans inside were shelled.

A delicate girl with shoulder-length hair landed twenty meters away from Cicero, her white skin not at all like the natives of the Rat City. Some of the filthy men in the audience began to stir in their lower bodies when they saw the fair-skinned and beautiful young girl.

The girl's right arm was wrapped in bandages, and her eyes were sharp and silver.

It was through the clues of the family that he went to Europe and went deep into Rat City to try to win Yu Xiaoxiao, the core of this rare level.

At the top of the spiral prison pit, the black core suspended on the central round platform is exactly the same as Yu Xiaoxiao's assassination skills.

"It's really a fair-skinned and young human being, I won't kill you, it's quite good for such a woman to be my wife."

Seeing Yu Xiaoxiao's true face, the plague prince immediately showed a greedy complexion, and the claws of his arms stretched out, and attacked Yu Xiaoxiao at the same swift speed.

"Shredding you."

The left and right claws attacked alternately, and Yu Xiaoxiao, who used the dagger to block, retreated step by step, and even under the opponent's several consecutive attacks, the dagger in his hand was completely shattered, and five shallow claw marks were left on the waist and abdomen.

Three meters behind him is the edge wall of the deep pit, and there is no way to retreat.

"Cut off your limbs so you can't move, and I'll pick you up when we get home...... You don't seem to like to talk much. ”

When Cicero claws down, Yu Xiaoxiao will use the wall behind him to fly.

"I knew you were going to dodge like this." Cicero, who had already predicted Yu Xiaoxiao's next move, controlled the agile rat tail behind him, and Yu Xiaoxiao, who was wrapped in the air and unable to dodge, saw that the battle was about to end.

At this moment, Yu Xiaoxiao's breath suddenly changed.

The storage ring fluctuated in space, and a special short knife hung on Yu Xiaoxiao's back.

The bandaged right hand pulled the glossy black blade out of its scabbard, and a whisper of curse spread through the arena.

The approaching little rat tail was instantly shattered, and there was a series of curse words attached to the wound.

"Ahh

The loss of the rat's tail caused Cicero to scream in pain, and his hair stood on end and he went into a berserk state.

"Shadow Kill."

Facing the manic nezumi who pounced on him, Yu Xiaoxiao suddenly disappeared in place with a special assassination method, and instantly appeared behind the nezumi.

Cicero instinctively grabbed behind him for the first time, and the Death Curse blade was already slicing into his throat from the side.

"Huh!"

The claws tore apart Yu Xiaoxiao's left arm, and the white bones in the flesh were clearly visible.

But Cicero's head had already fallen to the ground, and the death curse covered his body through the carotid artery in his neck, and the nezumi was completely dead, and there was no chance of survival.

"Winner, come and claim your reward."

Yu Xiaoxiao circled up the path at the edge of the spiral prison pit, and in the hands of the tournament leader, he received the prize of the tournament champion - a black rare core.

At this moment, a man with eight tails and a mouse-like face protruding fell from the sky. This person is none other than one of the several supreme rulers of Rat City, Rat King Rot.

"Outsiders kill my child and want to take away the rare core that our Rat City spent a lot of life for, and look for death."

The gap in the realm made it difficult for Yu Xiaoxiao to move for half a point, and when the Rat King's claws arrived, a kind old man in the crowd came to Yu Xiaoxiao's side in an instant, and smashed all the claws of the Rat King with one palm.

"Xiaoxiao, you can withdraw from Rat City first, Yu Feng and the two teams of family members are picking you up outside the city, and I will leave it to me here."

"I'm sorry for Grandpa Fu."

Professor of Dihua University School of Medicine, head of the Yu family, and master of traditional Chinese medicine, accompanied Yu Xiaoxiao in the rat city throughout the process. It can be seen that Fu Ye loves a little.
