This made Ethan Brooks involuntarily take a sharp breath—just how dense was the spiritual energy of heaven and earth here, that it had actually condensed into a mist? In the outside world, spiritual energy did exist, but it was so thin as to be invisible, only sensed during cultivation and then absorbed.

However, within the Human King Tower, the spiritual energy was so rich that it had turned into mist. Cultivating here for a single day was probably equivalent to half a month outside.

He absorbed it for a moment, only to feel the spiritual energy in the Human King Tower rapidly transforming within his body into pure postnatal internal force, circulating through his meridians, far surpassing the speed of cultivation outside.

All of this was indeed real. Perhaps, in just ten days to half a month here, he could advance from the third to the fourth level of the postnatal stage.

This delighted Ethan Brooks. He had been troubled about how to quickly improve his cultivation, but the appearance of the Human King Tower had given him a tremendous surprise.

But... where exactly was the Human Emperor’s Trial?

Ethan Brooks quickly scanned his surroundings, but inside the tower, aside from the spiritual mist, there was nothing else.

The Human King Tower was very mysterious. It seemed to be more than just a simple magical artifact; it also contained the Human Emperor’s Trial. Was it really just the ancient weapon of the Human King from the past? At this moment, Ethan Brooks couldn’t help but harbor deep doubts.

Suddenly, the spiritual mist before his eyes dispersed, and a mysterious path appeared, leading to an unknown destination, shrouded in mystery.

But Ethan Brooks had no other choice. He could only step forward, walking ahead one step at a time. The sound of his footsteps was clear and distinct. After half an hour, his vision suddenly opened up, and he arrived at an open space. Compared to where he had first appeared, there was now an ancient stone door.

“Welcome to the Human Emperor Tower, true throne holder Ethan Brooks, identity confirmed!”

“Push open the stone door to begin the first stage of the Human Emperor’s Trial! Complete the first stage to receive a reward!”

The emotionless voice sounded again after a long absence, but it startled Ethan Brooks once more. This wasn’t the Human King Tower, but the Human Emperor Tower. Could it really be the supreme artifact of the Human Emperor, ruler of the world?

The ancient stone door was plain and unadorned, but for some reason, Ethan Brooks felt it was anything but ordinary.

As for the reward for the first stage, he was quite expectant. After all, this was the Human Emperor’s Trial—the reward couldn’t possibly be mediocre.

Beside him, a stone stele was embedded in the ground, with a line of ancient characters clearly appearing: First Gate, eighteen thousand jin!

Eighteen thousand jin—not bad.

He simply nodded and, almost without hesitation, stepped forward to push. But the stone door... didn’t budge an inch.

Ethan Brooks gave a wry smile. Only now did he remember that he was no longer the supreme being who once dominated countless domains, but merely a weak cultivator at the third postnatal level. How could he possibly push it open?

The limit of the ninth postnatal level was only four thousand jin, and he was just at the third level. Eighteen thousand jin... when would he ever reach that?

Unless his Sacred Body bloodline awakened—otherwise, it would be impossible!

He sighed in admiration. Truly worthy of being the Human Emperor’s Trial—just entering the first stage required the terrifying strength of eighteen thousand jin to push open the stone door. This was a trial prepared for the strongest geniuses of all realms.

In his previous life, he would have definitely qualified for the trial, but now, having only recently awakened... he was still far from ready.

“Failed to open the door. Physical strength does not meet the trial requirements. It is recommended to cultivate the Overlord’s Saint-Refining Art to strengthen the body and meet the requirements!”

Overlord’s Saint-Refining Art?

The cold voice sounded again. While Ethan Brooks was still in shock, a series of images appeared on the ancient stone door. Each image depicted a person performing various strange and difficult poses, with clear diagrams of energy pathways on the body—thirty-six images in total.

At the same time, a stream of information appeared in Ethan Brooks’s mind: “The Overlord’s Saint-Refining Art, a body-refining method created by the ancient Supreme Lord. When cultivated to the limit, one can split heaven and earth with a wave of the hand, shatter stars with a punch...”

Chapter 12: Overlord’s Saint-Refining Art

“The Overlord’s Saint-Refining Art, a body-refining method created by the ancient Supreme Lord. When cultivated to the limit, one can split heaven and earth with a wave of the hand, shatter stars with a punch...”

A detailed stream of information appeared in Ethan Brooks’s mind.

According to the introduction, this was a peerless divine art created by a supreme being in ancient times—a body-refining method. Once cultivated to the limit, it could shatter heaven and earth, split stars beyond the domain with a single breath, its power boundless.

Ethan Brooks couldn’t help but take a sharp breath. This was actually a supreme divine art created by a mighty figure—such an existence could truly open up a world of their own.

And the title Supreme Lord—just hearing it, one could tell it was an extraordinary figure. Because he had also walked the path of body refinement, in his previous life Ethan Brooks had learned some information about this Supreme Lord, a supreme being who dominated the world in ancient times.

His physical body was invincible, his fists said to be unmatched under heaven.

A body-refining method left behind by such an existence was naturally extraordinary.

On the stone door, thirty-six diagrams of the human body in cultivation appeared, each with clear training pathways.

Looking at these diagrams, even with Ethan Brooks’s discerning eye, he couldn’t help but give a thumbs up.
