The Strongest Body Customization System

On the way back to the cave, Ian ran so fast that his silhouette turned into a shadow under the night. His legs and calves have been designed to efficiently generate explosive force. The muscle fibers were biased toward speed and agility, so even though his body size grew. He was still as agile as when he was 5'9.

The average height of humans on Earth before he was transmigrated was less than two meters. Now, with his size, he had far overshadowed the NBA players by a large margin. How exaggerated is 12.30 feet? Not to mention, most tall people are scrawny and frail because it is more difficult to fill their frames with muscle.

But Ian's frame had been filled with explosive muscle which was very impressive for his height.

Just like that, as Ian ran, with every step, the ground shook with his weight. Compared with heavyweight boxers or MMA fighters, their weight was a fart to him now. He could even lift them without effort.

Ian's bigger body size, filled with practical muscle designed for combat and agility, made him a literal killing machine.

Suddenly, a dark shadow jumped towards Ian. It was too sudden and caught Ian off guard. Then, Ian saw a cheetah with black fur and white dots all over its body biting his left arm ferociously.

The pain made Ian almost scream. Ian bared his teeth and swung his left arm forcefully. The sheer force and weight shook the cheetah away and hit a tree with a loud bang.

Ian looked at the bite marks on his left arm and the small wound. Yes, even with the bite force of the cheetah. It didn't manage to penetrate his large arm. The fang could only get through his skin but not the large muscle on his forearm.

"It seems I need to be more careful in this place. Even with my body size, this beast didn't hesitate to attack me."

The small wound and traces of bite on his left arm quickly disappeared.

Ian saw the black cheetah and finally managed to take a good look.

It is 4.5 feet in length, at a height of 3 feet. Ian surmised that the black cheetah weighs 64-75 kilograms. It wasn't much different from Cheetahs on Earth.

Ian was quite speechless. Where did this cheetah get the courage to attack him? Ian towered at the cheetah. His burly figure envelopes the cheetah.

The black-furred cheetah growled at Ian and dashed towards him again. It felt furious as its sneak attack was shrugged off by the big creature in front of it.

"What a fool."

Ian was quite impressed at the explosive speed of the Cheetah. But that's it. Ian threw a casual kick. The legs on his muscles were fully stimulated, and the force produced a crackling sound in the air.

BOOM!

The black cheetah met Ian's gigantic leg. Every bone on its body cracked. Its skull caved in, crushed to pieces by the huge force that Ian's kick had generated. The sheer weight of Ian's legs was multiple times that of the cheetah's entire body weight.

"One-shot kill."

Ian stared at the Cheetah's twitching body speechlessly. "There's something wrong with this Cheetah's head. Why is it so crazy?"

For his current 3.75 meter height, this midget, twig-sized cheetah wasn't even qualified to make him use his bone claws.

A few minutes later, Ian wiped out the blood on the corner of his lips. He just got 81 biomass from eating the entire cheetah raw. After eating raw meat, Ian was now quite well adjusted to its taste.

Although 81 biomass was quite little. Mosquito meat is still meat after all.

A shit-eating grin appeared on Ian's pale face. His crimson eyes reflected the surroundings. "I'm really looking forward to fighting those werewolves again..."

"Still, how should I explain my sudden growth in body size to the captain and others? I couldn't say that it's puberty, right?" Ian thought jokingly with a light chuckle.

It's such an excuse; even a five-year-old boy won't believe it.

"Well, I'll just say I broke through and became a true vampire."

...

Ian arrived in front of the cave without encountering trouble along the way. Even though his strength and speed had increased drastically due to his larger stature. He didn't dare to be arrogant at night.

If he encountered those big predators that were significantly bigger than him. What would he do? Pound for pound, even amongst 3-meter tall creatures, he was far superior because he was a vampire with enhanced five senses, strength, and regeneration factor.

'I heard that those true werewolves are five meters tall. They can resist most rifles and ordinary cold weapons with their body alone. If I want to fight them, even my current body size isn't enough to bridge the gap.'

Like vampires, werewolves had ranks; lesser werewolves, true werewolves, and high werewolves.

The higher the rank of wolves, the tougher and bigger their bodies are. Unlike vampires that always remain the same in body size, but still grow stronger due to their blood purity and awakening blood skills. Fortunately, werewolves can't awaken abilities. Their bodies only get bigger and stronger but that's it.

For this reason, vampires had the upper hand at the later stages and finally bridged the gap brought by differences in Physique.

For now, Ian understood that he could not afford even the cheapest blood core. So he decided on a route similar to werewolves... That is, he increases his body size and muscle over time to strengthen himself. Maybe in the future, he will become as big as Godzilla and King Kong in the movies on Earth. Nah, even surpassed them!

Unlike werewolves, Ian doesn't have a limit on increasing his body size as long as there's biomass to spend. On the other hand, werewolves had a limit on how much their size could grow. Not to mention, the bigger they get, the more it affects their mobility. Ian would be far more agile than them.

It was said that high werewolves are at least 20 meters in height. Far surpassing the size of the Titans in AOT.

After all, regular titans range from 3-15 meters. While Berthold's armored titan stood 15 meters in height.

It could be said that high werewolves far overshadowed the true werewolves. So is the gap in strength. Even the beast titan, which was already so gigantic in AOT, was only 17 meters (55.8 feet) tall!

'How much biomass do I need to grow 20 meters? 20 x 500... That is 10,000!'

Ian calculated in his heart.

At that time, he would be even bigger than the beast titan!
