Mortals cultivate immortality, and their IQ is playing with their heartbeats

Li Chengfeng pondered carefully, slowly comprehending. After a moment, he nodded, smiled slightly, and disappeared.

Now a second-tier Ancient Demon, he arrived at the mysterious place, the Ancient Demon's cave dwelling, the Black Lotus Buddha Heart Pagoda, the place of the Ancient Demon's head.

Here, he saw the artifact spirit of the old man's cave dwelling. The artifact spirit was dumbfounded when it saw Li Chengfeng.

"You advanced to the second tier of Ancient Demon so quickly, it's unbelievable! You're the fastest to advance to the second tier, truly worthy of being someone valued by the master."

Li Chengfeng smiled and said, "I have already advanced to the second tier of Ancient Demon. Please open the door to the cave dwelling, Fellow Daoist. I want to see what kind of treasures were left for me."

"Hahaha," the artifact spirit laughed. "Okay, okay."

As it spoke, a cave dwelling door from the second section appeared. Li Chengfeng didn't hesitate.

Transforming into his Ancient Demon form, he threw a fierce punch. With a 'boom,' the door exploded open, and he entered inside in an instant.

He saw countless demonic energies flowing within. At this moment, he seemed to enter a special state, sitting cross-legged.

These pure demonic energies were the reward the Ancient Demon left for him for advancing to the second tier. These demonic energies were extremely pure,

madly pouring into his body, causing his Ancient Demon power to rise steadily, constantly moving towards a more powerful force.

At this moment, the knot power on his forehead underwent new changes.

After a month, the demonic energy here was completely swept away.

Li Chengfeng had already reached the peak of the second tier and was approaching the third tier of Ancient Demon. As long as he survived the tribulation,

he would be a true third-tier Ancient Demon. For Li Chengfeng, this was simply a piece of cake.

His eyes were bright, and he laughed heartily, "Indeed a good treasure."

Because after absorbing all the demonic energy, in the center, there was a huge horn inserted. This was actually a horn from the head of a ninth-tier Ancient Demon, which could be used to refine magical artifacts.

Li Chengfeng waved his hand, and the horn flew over, landing in his hand.

He didn't rush to refine it but put it away and flew out of the Ancient Demon's cave dwelling.

Just as Li Chengfeng flew out of the cave dwelling, the artifact spirit said, "Fellow Daoist, I hope that next time you return, your strength will be further improved."

Li Chengfeng smiled and said, "Don't worry, next time I come, I will definitely have even greater progress."

This time, he finally flew back into the ancient tomb of the Ancient God.

At this moment, his Ancient Demon had advanced to the third tier.

It was a pity that there was no lightning here.

He didn't rush to break through but instead decided to raise his strength to the late stage of Refining Void before exploring, which would be the safest approach.

So, he took out the token and waved it again, returning to the mysterious secret realm,

leaving the Ancient God's cave dwelling. Coming outside, he sat cross-legged. With a shake of his body, countless clones shot through the air.

They were all transformed from runes. Li Chengfeng had also deduced a special cultivation method, Rune Clones.

Because all the cultivation methods in his body were unified, it could be said that there were ten thousand, or even a hundred thousand, runes combined together in his body.

At this moment, with a sudden transformation, he turned into hundreds of thousands of runes, shooting through the air and flying rapidly towards the east, south, west, and north of this secret realm.

But Li Chengfeng transformed into hundreds of thousands of rune clones, and they occupied various places, absorbing the spiritual energy of this secret realm. Their speed had absolutely reached a terrifying level.

As time passed, its power became stronger and stronger.

Finally, he reached the late stage of Refining Void.

At this moment, all his clones suddenly returned to their positions. In front of him were three kinds of materials, all of which were metal elements.

Using Jiuquan meteorite iron to refine flying swords was already familiar territory. For him, it was simply easy.

Soon, three more flying swords were formed, namely the Heaven Metal Sword, the Emperor Metal Sword, and the Human Metal Sword. The three golden flying swords of Heaven, Earth, and Human were integrated into them,

and fifty-two flying swords flew around him again. His strength officially entered the late stage of Refining Void.

At this moment, a powerful aura burst out from his body,

and the entire space was shaking. He knew that his Life and Death Space was also on the verge of breaking through, but he suppressed it.

This time, he wanted to completely integrate the Life and Death Space with this secret realm and the Ancient God's tomb,

which would definitely reach a very terrifying level. Once this thought appeared, it was difficult to restrain.

Li Chengfeng was still the same as before, pursuing perfection and not breaking through rashly. Instead, when he advanced to the Body Integration stage,

he would expand the Life and Death Space, turning it into a true world. At that time, his strength would be truly terrifying,

Although it was only the Body Integration stage, it would be enough to compete with the Great Ascension stage. This was his calculation. Whether he could reach this level by then,

would still depend on how great the opportunity he obtained this time was. If the opportunity was in place, killing enemies across realms would be within reason.

Thinking of this, he began to study wood-attribute cultivation methods.

He now had the wood-attribute cultivation method of the Azure Dragon Clan, plus the Ancient Demon, Ancient Demon, and Ancient God.

Finally, he obtained a special power within their bodies,

and deduced the cultivation method for the late stage of Refining Void. Once the cultivation method was completed,

he immediately had a special psychic feeling. Whether it was strength or opportunity, it had reached a level that satisfied him.

Calculating the time, thirty years had passed.

Thirty years was nothing to a Refining Void cultivator. It was like a flick of a finger.

This time, Li Chengfeng was fully prepared and had pushed his strength to a new peak. He had also deduced the cultivation method for the late stage of Refining Void.

After entering the Ancient God's Tomb and absorbing the power inside, he could reach the peak of the late stage of Refining Void. After refining three more flying swords,

he could advance to Body Integration. Then, by upgrading his own Life and Death Space, he could rest easy.

Li Chengfeng flew away, carefully displaying the power of divinity, and the power of the Ancient God permeated.

At this moment, he knew that there must still be dangers in this ancient tomb. There should be many mechanisms inside, and one careless move could lead to death here.

Although he had advanced to the late stage of Refining Void, he was not so powerful that he could sweep across and be invincible. Caution had always been his motto, and he kept probing and flying.

Perhaps it was because his caution had taken effect, and coupled with the incomparably powerful Ancient God power in his body,

he was able to continue unimpeded until he flew to a barrier, where his path was blocked.

Li Chengfeng was also shocked at this time. It turned out that the other side of this barrier was a small world.

The barrier on the outside seemed as thin as a cicada's wing, but Li Chengfeng understood that even if he went all out now, he might not be able to destroy it.

This meant that behind this must be the true core of the Ancient God's land.

Since it was a small world, it was also possible that there were Ancient Gods inside who had not yet died.

This would definitely not be good news for Li Chengfeng.

Li Chengfeng narrowed his eyes, staring intently at the small world opposite. He saw a peculiar scene presenting itself in that world.

Layers of clouds and mist swirled around, dreamlike and illusionary, with colorful lights flickering in between,

sometimes weaving into gorgeous patterns, and sometimes scattering into starlight.

Under the cover of that light, mysterious palaces seemed to be looming, exuding an ancient and mysterious atmosphere.
