Invincible Super System Modifier

Black light gathered on his foot, increasing the strength of his kick.    

Boom!    

With a loud sound, the man's kick hit the ground. The ground beneath his feet shattered due to the tremendous force of the kick.    

Even though the man had used all his strength in this kick, the monster was still as steady as Mount Tai. It did not take half a step back!    

However, he himself staggered back more than ten meters.    

His face was pale, and his right leg was shaking violently. Because the force from the kick just now made him feel as if his leg had been broken.    

It was really too hard.    

That kick was as if he had kicked an iron plate full of steel thorns.    

"How is this possible?" He stared at the monster in front of him.    

This monster was simply too powerful. It had already exceeded his expectations. He had never seen a monster with such powerful defensive abilities before!    

"Not good!"    

At this moment, another alarmed cry came from not far away.    

The man looked in the direction of the sound, and his pupils shrank immediately. A tall barbaric bull was following hundreds of zombies toward them.    

After the transformation, the barbaric bull's body also changed drastically.    

This time, it didn't grow bigger. Instead, it shrunk by half. However, its strength was dozens of times greater than before.    

It felt like it had returned to its original state.    

Looking at the surrounding zombies and the two S-class monsters in front of him, the man's face turned pale, and he looked panicked.    

His legs were still injured. How could he fight them?    

He couldn't even escape.    

He would die for sure!    

Crying! Crying!    

At this moment, the monster made its move. Its sharp claws waved again, aiming at the man's head.    

However, when the claws were only half a meter away from the man's head, they stopped moving. Lin Fei suddenly stood in front of the man and grabbed the claws.    

Lin Fei casually pushed the monster a dozen meters away and said, "This trouble was caused by me, so let me take care of it."    

The man looked at the figure in front of him in disbelief.    

Wasn't this person in front of him unable to dodge even a casual attack from him back then?    

"Aren't you the survivor here?" He said in shock, "Why did you block this monster's attack?"    

"Of course I lied to you." Lin Fei said, "I heard from the guard's little brother that you are very strong and have superpowers that I have never seen before, so I was curious and came to take a look."    

"What?!"    

The man was shocked and could not believe the truth.    

At this moment, the monster rushed over and waved its claw at Lin Fei.    

"Instant kill, close."    

Lin Fei wanted to see the power of his karma, so he turned off the instant kill and raised his hand to grab the monster's claw.    

Bang!    

He caught it. The claw was caught by Lin Fei and could not move.    

Lin Fei took a step forward and punched the monster in the stomach.    

Bang!    

Another muffled sound was heard. The monster, which had just taken a full force kick from the man, was pushed back dozens of meters by Lin Fei's punch, leaving hundreds of feet deep footprints on the ground!    

Although it was not as powerful as an instant kill, it was still powerful.    

"Instant kill with one strike, activate."    

The man was stunned when he saw Lin Fei's punch push the monster that he had been fighting for a long time back dozens of meters.    

What kind of strength was this?
