Blood Titan System

This feeling was quite exceptional. The changes within his body by the genetic serum was massive but Erian didn't dare use it for a second period of time as the eruption of the serum was really savage, if it weren't for his strong physique, his gene structure would have been destroyed by the feral response of the serum.

What Erian didn't know was that no newly transformed Titan would have dared to use the serum within the first month of their Titan transformation as their DNA helix would collapse from the overbearing might of the serum. It was unknown how Erian had missed such important information. Luckily, he was able to withstand the might of the serum.

A loud snoring soundwave bounced off his walls as he dozed off. The entire day had exhausted him mentally and he needed to rest.

Erian was jolted awake by a loud but muffled explosion whose vibration traveled along the foundations of his building. He frowned as he checked the time, he wasn't even an hour into his sleep before it got interrupted. Even on earth, except he wakes up himself, he absolutely loathe to be woken up especially hen he was already starting his deep sleep.

The door violently swung aside as Erian exited his room with a murderous expression on his face. His were no were to be seen as it was midnight at this point, they should be in their rooms. Another loud rumbling sound echoed, as though two heavy tons of flesh were colliding forcefully against each other with their shockwaves spreading in all corners.

By this point, Erian had already exited his building, checking the situation. The source of the disturbance was actually two 10 meters tall unknown titans battling against each other about half a kilometers away from his building. This made Erian frown since there are rules against students freely shifting to their titan form this close to the living area. He wasn't able to think too deeply about things when the fist of the two massive titans collided against each other, causing  another destructive shockwave that rippled towards Erian, blasting right though him.

His body had only drifted an inch backwards when Erian slightly spread his legs apart, his feet slamming forcefully as his stance steadied his body to the ground to the ground like a nail.  His hair and his clothes flapped backwards from the violent wind.

There were a few students gathered outside already to witness the epic battle between two titans. Some of them hadn't transformed yet which is why while they are filled with envy, they are equally excited to see the two gigantic genetic monster fight. Apart for Erian who was close to the battle area, the other students were more than half a kilometer away from the battle, to avoid being injured by the destructive shockwaves from the battle.

As their fist collided, the two Titans shifted backwards but the first Titan with grey hair and terrifying bulging muscles took a single step back while the second titan with dark hair and a fit body took three heavy steps backwards, causing three loud explosions on the ground as crater 5 meters wide was created. This result instantly revealed who was weaker and the Titan who was stronger.

"Roar!"

Perhaps in embarrassment or perhaps in anger, the weaker titan with dark hair color roared explosively. The deafening sound traveled for miles as his ten meters tall body abruptly charged forwards like a raging bull. His speed was so fast the wind screeched loudly and before the dark haired titan should react, the dark haired titan was already in front of him. This speed shocked everyone present.

"What speed!" "See the black jet smoke coming from the soles of his leg, he has activated a skill, which means this guy has definitely acquired an Agility based combat tactic!" The students discussed excitedly amongst themselves.

A sonic boom caused the air to ripple as the fast dark haired titan let loose an heavy punch which slammed right into the jaws of the grey titan.

"Bang!"

The grey hair titan massive body was blasted backwards into the air, crushing the nearby trees and causing clouds of dust to spread in the atmosphere. Anther jet of cloud smoke escaped the dark haired Titan's feet as his speed increased once more to appear by the side of the struggling grey haired titan.

His foot high up in the sky like a hammer, he slammed it directly into the skull of the grey hair titan who wasn't able to react as the force within the kicked slammed into him, blasting him deep into the sand with fragment of rocks and shockwaves spreading out in all direction.

The dust cleared up and a hundred meter hall was revealed. Within the hole stood a ten meter tall titan proudly standing over a two meters tall youth who is currently covered with blood. The grey haired youth titan form had been forcefully canceled since he had been knocked unconscious by the leg strike. If he had learnt any combat tactic, maybe he wouldn't be in this type of situation but there was no room for regret.

Fumes of hot steam escaped the dark-haired titan body as his rapidly active cells slammed against each other, causing the body to be at a high temperature that quickly evaporated the sweat his body was producing. The grey haired titan picked the unconscious youth like he was holding an ant and brought him directly before his face. A soft squeeze and the sound of bones breaking echoed.

"Ahhh!"

The pain jolted the grey haired youth awake as he let out a miserable scream at the pain of his bones being crushed. It didn't take long for him to realize his situation. With a bitter expression on his face, he turned on his holo watch and swiftly made the transfer.

An intelligent sound of satisfaction escaped the grey hair Titan's but the malicious expression on his face didn't fade in the slightest. Instead, he grinned. Making his muscled cheeks stretch out weirdly. He gave another squeeze.

Just as the dark haired titan was about to
