Invincible Super System Modifier

"The city walls have fallen. You have already lost. If you continue to resist, only death awaits you." I didn't want to hurt you by accident," said the zombie, so I stopped the zombie attack. I hope you can give me a satisfactory answer."    

"Otherwise, I will move this place."    

The zombie looked at the girl and said, "Especially you, little sister. You seem to be stronger than them."    

"Join us, and you'll get stronger power!"    

The girl said without thinking, "I refuse."    

"Is that so?"    

The zombie smiled and said, "That's a pity."    

As soon as it finished talking, it disappeared. It was so fast that it teleported and appeared behind the girl in the blink of an eye.    

It threw a punch!    

Although the young girl didn't expect his opponent to suddenly attack, she was still on guard.    

The moment the other party disappeared, she realized the danger.    

She immediately erected an ice wall around her, a meter thick ice wall.    

Boom!    

However, in an instant, the ice wall behind the girl exploded. The fist shattered the ice wall and mercilessly landed on the girl's back.    

Bang!    

With a muffled sound, the girl flew out and powerlessly fell to the ground.    

"Cough, cough -"    

The young girl lay on the ground and coughed out a mouthful of blood.    

Her face was pale as she looked at the zombie who was walking toward her step by step. Her eyes were filled with coldness.    

She had expected the zombie to be powerful from the beginning.    

However, she didn't expect the zombie to be so much weaker than her.    

"Those who refuse me will only have one outcome, and that is death." The zombie stood in front of the girl, looking down at her with disdain.    

It was trying to kill the chicken to warn the monkeys, telling everyone what would happen if they refused.    

All the S class were terrified.    

The girl, who was also an S class, was defeated in one move. Even if they were in her shoes, they wouldn't think that they could defeat this zombie.    

Why was there such a powerful zombie?    

Could they really defeat it?    

"I won't give you a second chance to refuse me." The zombie said.    

The girl shakily stood up from the ground and said, "Someone will take revenge for me."    

"Who?"    

The zombie smiled and said, "I have something to tell you."    

"In fact, I'm not the strongest one here. There's someone stronger than me. I think it has already started a massacre in the city," it said.    

Hearing the zombie's words, everyone's faces changed.    

The zombie in front of them had already defeated an S-class superpower possessor with a powerful punch. What kind of existence was stronger than it?    

Besides, such a terrifying existence was still in the city, yet they didn't know anything about it.    

On the city wall, the vice-president's face turned pale. An existence even scarier than that zombie was in the city?    

She turned back to look at the city, and found that it was terrifyingly quiet inside.    

Why was it so quiet?    

Had they all been killed by the unknown zombie?    

The vice-president, the woman who had always been strong, felt her legs go weak. If she hadn't been holding the wall, she would have fallen to the ground.    

"No one can avenge you." Alright, said the zombie to the girl.    

It raised its hand to execute the girl in front of everyone, warning everyone on the scene that only death would await them if they became enemies with it.    

However...    

It had just raised its hand.    

Bang!    

With a loud bang, the ground behind it exploded, and a head flew up from the ground and fell heavily next to the zombie.
