Through the tempering of the murderous aura of the ancient monument, he inadvertently discovered that the control of spiritual will over one's own strength is more powerful than he imagined.

If a person's strength is rated at 10, then usually he can only exert 70% to 80% of it. This is the limitation of the human body. Some people may even be able to only exert 60% to 70% of it.

Even someone like Xu Feng, who can be called a genius, can only display 80% to 90% of his potential, and cannot display his full strength.

But after his willpower has been tempered, Xu Feng can now not only exert 100% of his full strength, but can also burst out to his limit and exert 110%, or even 120% or more.

And the more important point is that if the original Xu Feng burst out with all his strength, his fine-tuning control over the strength would certainly be insufficient, or even disappear completely.

If he were given an egg to hold in his hand, Xu Feng in his extreme state would definitely crush it accidentally.

But now, in the same situation, Xu Feng can be sure that he will never crush the egg in his hand.

This is an absolute control over one's own strength, which can only be achieved with strong willpower and mental strength!

Xu Feng didn't believe that other people hadn't discovered the benefits of this kind of murderous aura tempering, so this should also be the legacy of the ancestors to future generations.

This secret place is truly a treasure land for the future generations of the human race.

Putting aside all distractions, Xu Feng took a step back and punched the stone tablet silently.

A feeling of comfort all over the body made Xu Feng's eyes light up. The feeling after throwing this punch was indeed different from the previous ones!

This full-strength punch did not even create the slightest sound of breaking wind. After it landed on the ancient stele with a loud bang, it left a fist mark full of cracks on the ancient stele.

Then, a burst of explosions suddenly sounded, startling everyone.

Three punches.

With only three punches, Xu Feng smashed the ancient monument that was ninety feet high.

Another ancient animal skin scroll was suspended in a ball of white light. Xu Feng grabbed it and then slowly unfolded it.

"Five kills and three burns?" Xu Feng took a quick look and was suddenly shocked, with an incredible expression on his face.

Then he looked around vigilantly, then sat cross-legged on the ground and began to read the contents of the ancient scroll carefully.

It wasn't that he was too curious, but this ancient scroll contained some extremely important things.

"In ancient times, a god descended from the sky. He was as tall as a cloud and could change his form at will. He called himself the God of Desolation..."

"The God of Wilderness is so powerful that he can pick up the stars and the moon, and collapse the heaven and earth with a flip of his hand... I was delighted to see him, and we sat down to talk and exchange our cultivation experiences."

"He once said: 'The sky of the wilderness is not the real sky.' I didn't understand what he meant, so I asked him. He looked up at the sky and said nothing..."

"I gave him the imperial seal so that he could obtain the luck of the Great Wilderness. The God of the Wilderness was grateful for my generosity and left him a fighting method... but he said that only those with a strong physique could learn it."

"I have been in office for 1,600 years. Now I will step into the sky to see the real sky that the God of Desolation spoke of. Therefore, I leave this battle method in the Desolate Tower. I hope that future generations will study it carefully, comprehend this method of five kills and three burns, and protect our human race."

"This technique is extremely powerful, comparable to Wang Ce, with ingenious ideas and extensive implications. I hope that the younger generation will not force themselves, lest they make mistakes."

"Suirenshi stayed."

Then, there is a full article of secret methods.

After reading it through, Xu Feng no longer knew what words to use to describe his feelings.

He just murmured: "Suirenshi... Suirenshi, I seem to have heard this name somewhere..."

"Suirenshi is the name of a human emperor."

Just when Xu Feng was thinking hard, a voice sounded behind the monument next to him. A figure in white gauze appeared behind the ancient monument and smiled sweetly at Xu Feng.

Hearing this, Xu Feng's mind flashed back to what his grandfather had said: "The great emperor Suiren reigned for 1,160 years, abdicated the throne, and passed away."

"That day, strange blood fell from the sky, as if the sky was weeping blood. Thirty-six majestic peaks collapsed in the wilderness, seventy-two great rivers dried up, and dark winds blew for tens of thousands of miles. The ten great human kings ascended to the sky together."

"That day, the wilderness was filled with sorrow, as if the heaven and earth were moved, and blood rained continuously."

"The thunder from the sky is like rain, the fire from the ground is like the tide..."

"When the entire human race was in panic, the only seven remaining human kings returned and kept silent about the events outside the sky. They only said that the human race could enjoy 500 years of peace."

"For the next five hundred years, the immortals did not invade again. It was not until the sixth hundred years that the immortals came again."

"There is a rumor that the emperor Suiren died in the wilderness..."

"There is a rumor that the Human Emperor Suiren shattered the sky, walked out of the wilderness, and disappeared..."

Coming back to his senses and touching the ancient scroll again, Xu Feng unexpectedly felt an inexplicable sadness and heaviness, as if the animal skin scroll weighed a huge amount, pressing him to the point of suffocation.

"This ancient scroll was actually left by the first Human Emperor!" He was extremely shocked, almost as shocked as when he first saw the image of the God of Wilderness.

The Human Emperor unified the ten domains and led all human beings to survive, fight and struggle in this vast primitive land.

The meaning of its existence has already exceeded the original meaning of the word.

However, among so many descriptions, the human emperor Suiren should have fallen.

Xu Feng thought again that when Xuanzun ascended to heaven, he said that he wanted to go to heaven to take a look.

If Xuanzun is really a friend of the First Human Emperor, then he must know whether the First Human Emperor is still alive.

Unfortunately, Xuanzun also disappeared, leaving behind eternal regret.

Xu Feng was not surprised that the Human Emperor had met the God of Wilderness. After all, the ancient scroll he had obtained described the orthodox cultivation method of the human race, and there must be a close connection between it and the God of Wilderness.

So where did the human race's cultivation method come from? It must have been created by the first Human Emperor.

However, the Human Emperor actually heard the mysterious and powerful God of Wilderness say in person that this sky was not the real sky, which made him think of a lot of things inexplicably.

The existence of the immortals, the secrets of the mysterious world, the disintegration of the human race, and even the weird smile of Xian Zhen, the leader of the immortals, before his death!

The more he knew, the more confused Xu Feng felt.

It seemed as if there was some shocking secret that had been passed down from ancient times to today, and was about to slowly unfold before him.

He really wanted to know what the God of Wilderness meant.

However, all of this is Xu Feng's own secret, and at least it cannot be spread out now.

However, it was this battle method left by the Human Emperor that really aroused Xu Feng's interest.

After all, this was passed down by the God of Wilderness, so it must be suitable for him.

It just so happened that when Xu Feng no longer needed to use his Yuanli, he didn't have many fighting methods, so this tactic was just right for him.

After putting away the parchment scroll, he glanced at the person who had just spoken, who was the woman in white gauze, looking refreshed and energetic.

Seeing Xu Feng looking at her with bright eyes, Baisha blushed and lowered her head and said, "The secret realm will be closed in a few days and will be open soon. By then, there will be a teleportation force everywhere. I just came to remind you."
