As the small light bead at the center of the Dantian Qi Hai condenses, the Qi Hai meridians of the five internal organs form an interconnected trend, and the five elements are mutually generated and restrained, forming a never-ending internal circulation.

However, the qi sea of ​​the five internal organs has not yet liquefied and is not yet consistent with the dantian, so the efficiency of automatically absorbing spiritual energy is extremely low, just like a snail crawling.

Even so, Ling Tian still found it difficult to conceal his excitement. As the saying goes, dripping water wears away stone, and little by little, it adds up to a lot. As long as one lives long, how much can be accumulated?

"Liquifusing one Qi Sea has almost exhausted all my savings. I still have five Qi Seas to go. I have a long way to go."

"Now that the technique is complete, I will begin to practice diligently. I won't come out of seclusion until I have established my foundation."

Ling Tian gave himself a death order this time, so only those in the Foundation Establishment stage can be considered as immortal cultivators, and those in the Qi Refining stage are just stronger mortals.

…

In the tenth year after Ling Tian's retreat, Lu Chen's first clone had already arrived outside the Earth's atmosphere from the upper realm through the star domain teleportation array, but his face was not good at all.

"Damn the power of law."

Lu Chen cursed while attacking the boundary wall. Although he was a terrifying existence in the late stage of fusion, it was not easy for him to break the boundary wall facing the limitations of the power of the law.

"Delay will lead to changes. Although I have reached a level that is difficult for ordinary people to reach, there are still many old monsters who are hidden from the world, especially those in Piaomiao Palace. They will never give up searching for their treasures that have been passed down for billions of years. Fortunately, the Jingtian Bottle was broken and lost its aura, otherwise it would be my turn."

Lu Chen made a decisive decision. He immediately took out a bow and arrow that exuded an ancient aura. He used his strongest secret technique to condense a terrifying arrow onto it. He used thousands of years of his life to draw the bow with all his might. He aimed the arrow at the boundary wall, and burned all the spiritual power in his body to push it forward. "Boundary-breaking Arrow!"

“Swoosh~”

After a sound of breaking through the air, the arrow disappeared from the bow, and then a huge shock wave spread out. Upon closer inspection, a thin ray of light was slowly moving forward on the boundary wall, causing the boundary barrier to sink.

"Break it for me!"

Lu Chen shouted angrily, and just when the energy of the arrow was exhausted, he finally broke a hole more than three feet in the boundary wall. His face was slightly pale, and he was overjoyed in his heart. He didn't care about his excitement, and his body flashed and instantly disappeared into the boundary wall. The moment he came in, the boundary wall quickly closed together, and returned to its original state in the blink of an eye.

"Finally, I'm in. As long as I get the Pure Heaven Bottle and his body, losing a thousand years of my life will be worth it. Hahahaha!"

After laughing, Lu Chen began to feel unhappy. Although he broke through the boundary wall and came in, his terrifying realm was assimilated by the power of the world. Now he can only be in the great perfection of the foundation-building period. It is like it is easy to go from frugality to extravagance but difficult to go from extravagance to frugality. It would be strange if he could feel happy.

According to the memory of his dead clone, Lu Chen found his cave. He was not looking for any relics, but to extract the aura of the place where Ling Tian had been. Otherwise, with his current level, it would be like looking for a needle in a haystack to find a person on the vast planet.

"go!"

Lu Chen forced out a drop of essence and blood and shot it into the newly set up formation. After a buzzing sound, the center of the formation started to suck in gusts of wind and dust like a suction cup, and soon a small light spot condensed, while the essence and blood that had just been shot in quickly sank into the light spot.

After the light shone brightly, Lu Chen pointed his finger at the light ball and muttered something. With a wave of his finger, the light ball instantly disappeared into his forehead with a whoosh.

He closed his eyes and frowned slightly. After a while, Lu Chen suddenly opened his eyes, looked towards the southwest, raised the corner of his mouth, took out a shining long sword from the space ring and threw it into the sky.

The long sword seemed to have a spirit. It circled around the sky several times and gradually became larger. It stopped changing and flew back to Lu Chen after it was about ten feet long and two feet wide.

Lu Chen lightly tapped and stood steadily on the sword.

"go!"

At a command, Lu Chen flew away on his sword.

A few hours later, Lu Chen arrived at the crater. He scanned the area with his mind, and after a few breaths he discovered a clue. Then, with a flash of his body, he went down the passage at high speed.

After a moment, Lu Chen stopped at the entrance and looked at the defensive formation inside and couldn't help laughing, "Hahaha, such a crude formation can only be found in such a poor place."

Lu Chen's mind merged into the formation, and within a few breaths he found the center of the formation. He held the long sword and thrust it towards the center.

"Puff~"

The formation was broken, the illusion disappeared, and the entrance was suddenly revealed.

Lu Chen walked in and couldn't help feeling happy as soon as he stepped inside.

"It's actually a small world. I never thought I could come across such treasures. This trip was worth it, haha!"

…

"Someone's coming in!"

In the deepest part of the cave, as soon as Lu Chen broke the formation, Ling Tian knew that someone had broken in. Anyone who could break through the formation had to be at least in the Foundation Establishment Stage, which made him nervous. He had just broken through to the Foundation Establishment Stage and was at a critical juncture in consolidating his realm, so he didn't dare to move rashly. He just hoped that the other party would discover this place later.
