He walked up to the wooden weapon rack and picked up a curved knife.

Thud!

He stabbed the knife into his left arm. It didn\'t pierce through the skin, stopping at the surface as if it had hit a very hard wooden surface.

David slowly applied more and more force onto the knife. The strength applied to the knife instantly went over 10 % of his strength, then slowly 20, 30, 40, 70…

Psiii!

After a slight noise, the tip of the knife went through his skin, and David immediately stopped applying the force. He looked at the point on his skin that the knife had pierced.

There was a very little red dot on his skin, and a tiny bit of blood was slowly flowing out of it. However, it quickly solidified, as if it was an injury that a needle left behind.

After placing the knife back in the weapon rack, David pinched the part of his left arm that got stabbed.

"Increased points in endurance and defense. That means that as long as my opponent\'s strike with a sharp weapon has less impact than this, I won\'t get injured. But if the weapon is dull, then it\'ll be much easier to defend against. I think even 500 pounds of strength with such a weapon won\'t injure me at all."

David rubbed his hands together, and they made a vague screeching noise, as if his hands were two rough metal plates.

"The martial arts in this world are very impressive. They must be on the same level as the previous world Iron Body.

​ "I will specifically test my punches next."

David slowly walked up to a black heavy platform that was standing in the middle of the training room. He lowered his back and swung his arm, throwing out a side punch.

Bam!

The flat long surface that looked very much like a wall, did not even shake in the least. However, the ground shook violently like there was an earthquake. For a time they vibrated aggressively, making buzzing noises

David drew back his arm and punched straight this time. The fist shot out like an arrow and hit the flat wall-like mechanism right in the center.

Boom!

Bang!

Numerous holographic numbers floated upwards as the measuring equipment started to shake slightly.

Suddenly David releases an enormous roar.

"BANG!"

The words "Rank 7" floated in mid-air and the mechanism released a slight droning sound as though it was about to be destroyed.

After a while, the dust gradually calmed and settled back on the ground. David squatted down and made some careful observations.

The wall that made of Meteoric metal. It was painted black and screwed to the ground by long iron screws. Its bottom formed an shape to secure it against impacts from all angles.

Right now, all the hard iron screws were perfectly pulled out of the floor without any sign of damage on them.

David picked up an iron screw that was about the length of the index finger and looked at the others as well. Even with his enormous force, he shouldn\'t have been able to lose the screws.

"Is it because of vibration? Apparently, it has this effect on nails, I wonder what kind of effect it would have on normal humans? It seems very similar to destructive frequency."

He stood up as he thought about it and stretched out his arms and chest by swinging his arms horizontally backward. The jacked muscles on his back were compressed and bumped against each other as he moved his arms. It felt like there were strands of iron chains twisting and intervening with each other under his skin.

Si…

Hu...

He took a deep breath as he closed his eyes and recalled the moment when he punched out.

"It\'s a vibration… A strong vibration."

He threw out a punch into the air, using the Shot Form.

After he punched out, there was a vague whistling sound.

"The strength would cause vibrations after it\'s used, and transfer a huge vibration in the opponent. This type of attack would deal a great amount of damage to living creatures\' internal organs. I have to find an opportunity to test it out since I\'m still not sure where exactly I stand in terms of combat abilities right now."

"Ans I have to find an opportunity to integrate my form of martial art to this world\'s form of martial art. It shouldn\'t take much longer to reach my peak."

David released a satisfied smile and drew back his fist. He stood up straight. He stretched his neck and looked at his well built upper body. It was at that moment that he realized that he had turned from a weak teenager to a slightly tough, muscled man.

"This change is really significant when considering that only a day I regained my memories."

A few thousand meters outside the school, the sky already dark.

David walked along the sidewalk into an alley it was dark, but it was a relatively short cut to his house. Very soon, he heard sounds of fists pounding. Between each punch, someone whimpered and moaned.

"Catch him! Don\'t let him get away!"

"Pablopassed out! Goddammit, this guy\'s attacks are strong!"

"Be careful of the gap! Don\'t give him any opportunity!"

A group of men shouted at each other; it seemed like they were trying to attack someone.

David pursed his lips and stood in the shadows at end of the alley and looked in.

On the muddy road, a group of men from some sort of gang or Organization surrounded two skinny youths. A large man stood outside of the circle and watched the fight with a cold expression on his face. He remained alert of any noises around him.

On the ground were three to four adult men, all of whom seemed to have passed out from being punched in the head.

David was slightly surprised as he estimated the extent of the injuries these members received.

"This level of strength is similar to rank 7! Could it be that all these casualties were caused by these two children?"

He moved his gaze onto the two youths.

One was a boy, and the other was a girl. The boy was handsome, and the girl appeared innocent. They were only around 15 to 16 years old, similar to David. However, from the looks on their face, it was obvious that this was not the first dangerous situation they ran into.

The two of them wore white sportswear. Their backs were against each other, and their stances in proper boxing stance.

"My father will be here to save me soon!" The boy sneered out of his teeth. "He won\'t let you off easy!"

"Don\'t talk too much! Save some strength!" the girl said in a quiet tone. On her waist, a black gun was tucked away.

The large man chuckled and speedily walked forward.

"Let me do the rest. You guys make sure he doesn\'t run away. This fella here is the Black Falcon\'s son. We finally captured him after much work; we cannot let our effort go to waste."

He marched inside the circle and stood still. One hand vertically shot up as the other hand\'s palm faced outside. Then he slouched. He positioned himself in the same stance as before.

Faintly, David noticed that his right hand turned even redder than before. It was as if his blood was congested, and his veins would pop at any second.

"Kid, I cannot believe you dare to fight me. You\'re courting death! If any part of your body ends up paralyzed, don\'t blame me."

"Cut the crap! Make your move!"

The young boy\'s body remained straight as he interrupted his opponent.

Before he could finish talking, there was a snipping sound.

A red shadow dashed across his chest. and his white uniform was silently sliced open. A red slash ripped across his wheat-colored skin as blood started to spew.

After the red shadow faded, it reversed back into the Large man\'s hand and dissolved into his palm.

The boy\'s face whitened. When the red shadow dashed across just now, he sucked in air to tighten his chest and had used his Metal Force to defend himself. If he had reacted any slower, the crimson knife would\'ve cut open his stomach. However, because he inhaled too much oxygen too fast and has rushed his Force forcefully through his body, he was having some difficulties breathing. His lungs felt like they were tearing apart.

He was only at the Star rank 7 stage but he managed to block an attack from a Meteor Expert which is very surprising!
