I built a floating city in the game.

"this......"

Mo Bai looked at the situation in the room, his pupils contracting slightly.

Inside the room, a man draped in a black robe was writing and drawing on a table. Next to him stood many cages, inside which indigenous people were suspended by chains.

Some of these indigenous people had bloodshot eyes and ferocious faces, while others had thick limbs and sharp nails, as if they had turned into wild beasts.

"Hmm, there's still too much Boiling Blood Grass. The test subject died in less than a day because its heart ruptured."

However, reducing the amount of product doesn't improve the effect. What should we do?

Hmm, how about we test it on the new players? They're physically stronger and can last longer.

Or how about... Number One?

The man in black robes pondered for a moment, then began to experiment with various test tubes, including extracts of herbs, powders made from crystal cores, and bone meal from magical beasts.

Various items boiled together in a specific combination, eventually turning into a vial of red potion which he held in his hand before heading to a back compartment.

As his spiritual energy spread, the scene inside the cubicle came into view.

Thick iron chains were driven deep into the stone wall, and five chains suspended a naked indigenous man in mid-air.

His muscles were exceptionally defined, and his physique was so imposing that he resembled an iron tower, giving off a powerful sense of awe.

His body was covered in blood-red marks with obvious elemental fluctuations, clearly indicating that they were all from the blood of magical beasts.

More importantly, Mo Bai suddenly sensed a chaotic elemental force within his body.

The earth, fire, and water elements are mixed together in a chaotic mess, like a time bomb that could explode at any moment.

Mo Bai was somewhat terrified by what he saw, yet he couldn't take his eyes off it.

This was the first time he had seen a human use their body to contain elemental power.

The man in black robes stared at the NPC's body with fascination, his eyes filled with fanaticism. His hand gently stroked the body, the muscles as hard as steel, which was simply his most perfect creation.

He walked over and poured the medicine into the man's mouth. Then he loosened the chains slightly and immersed the man's body in a bathtub filled with the medicine.

Having completed this step, the man in black robes stepped back slightly, looking on with some anticipation.

The change was rapid. In just over ten seconds, the person's body turned red at a visible speed, the muscles swelled rapidly, and there was a faint accumulation of keratin on the surface of the swollen muscles.

"what!"

The unconscious man let out screams, abruptly waking up from his coma. He clenched his teeth, veins bulged on his forehead, his face contorted in agony, and his eyes filled with struggle.

"I'm going to kill you!"

The man growled, but he only held on for a moment before his mind completely succumbed. He roared at the black-robed man, his bloodshot eyes filled with nothing but savagery, devoid of any reason.

The chains clanged, and the violent movements caused the bathtub to overturn on the ground. The man in black robes paid no heed, his eyes filled with excitement as he looked at the man's bulging muscles.

"It's done, it's done, yes, that's it, I'm going to succeed."

However, just moments later, the man who had been so swollen seemed to have lost all his strength, and he slumped down, suspended in mid-air by the iron chains.

"Um?"

"Huh? What's wrong?"

The man in black robes, who had been in a very favorable position, was stunned when he saw this scene.

"It still failed?"

"No, it's not a failure if you're not dead."

The man in black immediately walked over to the man and recorded all his physical characteristics and data.

After recording the information, he left and returned to the dispensing station to prepare the medication again.

Mo Bai, who was standing to the side, took a deep breath as he watched this scene.

"It's the same elemental fluctuations I sensed before, so we can be pretty sure that the elemental fluctuations I sensed before were all from this black-robed man conducting human experiments."

"in addition....."

Mo Bai looked at the man who had collapsed.

"What kind of potion was that? It can actually increase a person's physical fitness and directly increase their physical strength."

"The elemental forces weren't adjusted during the potion's production process, so the elemental forces within the potion were completely chaotic. Surprisingly, no one died after drinking it."

Looking at the man, Mo Bai couldn't help but mutter to himself, feeling that he was somewhat capable as well.

Otherwise, he would have been one of the corpses piled up nearby long ago.

The pit next to it was filled with corpses, and flies were swarming around it.

Thinking of this, and recalling the scene he had just perceived with his mental power, Mo Bai's face immediately turned pale, and his stomach churned. This made him quickly shift his attention and sense the chaotic elemental power emanating from the man.

To try to find the secret of how the human body contains the power of the elements.

He had just clearly seen that the three elemental forces were conflicting, resisting, and entangled with each other within his body, and then completely lost control during their operation, directly leading to the man's rage.

Later, it broke through the control and the elements rushed out of the body and spread out.

"Theoretically speaking, as long as I use my mental power to straighten out the elemental power within this man's body, he has a real chance to complete the enhancement stably."

They might not necessarily lose their minds.

Mo Bai took a deep breath and extended his mental energy to sense the elemental power that this man possessed.

The process of mental energy penetrating into the body was somewhat difficult and slow, but even with the man unconscious, the mental energy still slowly seeped in.

The first thing to do was to come into contact with the chaotic elemental forces.

Within his body, the elemental forces were in a chaotic state, like a hundred stretched-out balls of yarn being stirred together and then rolled back into a ball of yarn, so much so that it was impossible to see clearly, leaving Mo Bai somewhat bewildered.

However, he then hesitated for a moment.

"Never mind, let's sort it out little by little."

Mo Bai immediately set to work, first identifying the earth element and then sorting it out bit by bit.

He estimated that the total amount of elements in his body was only enough to cast one spell. It was quite chaotic, but the total amount was actually not much.

He extracted all the earth element in about ten minutes.

Then it took another ten minutes to sort out the fire element, and finally only the water element was left. The three elements coexisted in the body and were contained in some cells, flowing slowly within them.

Mo Bai looked at the cleaned-up elemental power. These cells flowing with elemental power seemed a little different from the other cells. However, before he could explore them, the excited man in black robes walked in again, grabbed the man's mouth, opened it, and poured the potion into it.

"Let's try again, I refuse to believe we can't succeed."

The man in black robes muttered incoherently, and as the potion flowed into the man's stomach, a violent force surged forth instantly. Wherever it passed, cells were torn apart, and the violent elemental power rushed in and merged into them.

Under the impact of this surging elemental power, the elemental power that Mo Bai had originally organized was instantly dispersed and directly merged into this chaotic element.

"what!"

This time it was a few seconds too late, but the man still howled in pain, his muscles bulging rapidly and radiating a reddish glow.

Upon seeing this, the man in black robes almost blushed with excitement.

However, what he was completely unaware of was that, right in front of him, while he was conducting his experiments, another person was stealing his results.

Mo Bai's spiritual power filled the man's body, sensing the surging elemental power and moving accordingly.

The ink cartridge in my mind spins at high speed, and every second seems to spark a burst of inspiration.

Suddenly, as he observed the surging flow of elemental power within his body, Mo Bai suddenly realized something when he noticed the trajectory of the elemental power's flow.

"Operation trajectory, operation trajectory!"

This corner, yes, that's right, this isn't the first time.

This angle, this relative direction, and so on... this shape, these nodes, how come they look so similar......"

Mo Bai couldn't help but gasp.

"Spell model?"
