May I seek good fortune and avoid misfortune, and live a long and prosperous life.

The next day, at Yuncheng Teahouse.

Li Heng found a seat in the corner, ordered a cup of tea, a plate of peanuts, and a plate of cooked beef, and then quietly listened to others chatting.

An hour later, Li Heng paid and left.

The next day, he went to the teahouse as usual, listened for an hour, and left on time.

This time, he heard a piece of news: Dong Ao Zuike had appeared in Yuncheng.

It turns out that one of the four Grandmasters who participated in the third martial arts competition at Wangchen Peak has been replaced, and the original Fairy of the Eastern Sea has been defeated by another Grandmaster.

This grandmaster-level expert thus successfully obtained the title Dong Ao, and was known as Dong Ao the Drunken Guest.

Upon hearing this, Li Heng became interested in this drunken man from the east.

So he spent the last few days lying in wait in Yuncheng, finally finding an opportunity to spar with him.

Dong Ao Zuike was a martial artist who appeared to be a middle-aged man in his fifties. After Li Heng explained his purpose to him, Dong Ao Zuike readily agreed to spar.

Li Heng only used one move, and this time he only used about 20% of his strength. As a result, Dong Ao Zuike was still blasted backward, his robes were torn to shreds, and he spat out a mouthful of blood. He suffered considerable internal injuries.

After the exchange, Li Heng immediately took his leave, while Dong Ao Zuike was extremely shocked, feeling that he had underestimated the heroes of the world.

He originally thought that his level of martial arts was the pinnacle, and anyone stronger than him could only be a legendary Celestial Realm expert.

However, he knew that the Celestial Realm experts were no longer in the same dimension as them, and that the Celestial Realm experts could not attack them.

Unexpectedly, a random mysterious man in black appeared and made him vomit blood with a single move.

The fact that the mysterious man in black could make a move meant he was also a Grandmaster-level martial artist, yet he managed to injure Dong Ao Zuike in a single strike. Dong Ao Zuike was completely dumbfounded. How did this person train to be so strong? It's unbelievable!

Even the strongest of the four Grandmasters, the Southern Swordsman, could not possibly have driven the Eastern Drunken Master to this point.

"The world of martial arts is indeed a deep and murky place. My master was right to tell me to stay home and cultivate more!" Dong Ao Zuike clutched his wound and slunk away.

On the other side, Li Heng stood on the top of the tallest building in Yuncheng, looking down over the entire city.

"Alas, there are no more martial artists in this world that I find worthy of my attention."

Li Heng finally understood the feeling of "how lonely it is to be invincible".

"I'm not going on any more travels. I'll return to the Poison Dragon Pool cave to continue my cultivation. This time, I won't leave seclusion until I've cultivated to the point where there's no more room for further cultivation!"

One day later, at the Poison Dragon Pool Cave.

Li Heng sat upright on the futon, closed his eyes again, and began to disperse his cultivation once more.

......

Fifteen years later.

A deafening sound came from inside the Poison Dragon Pool cave. Li Heng was surrounded by golden light, and his aura was extremely powerful.

"I've already restarted my training ten times, and I can still improve. Let me see where the limits of the 'Giving Up Health Preservation Technique' lie!"

"Continue to disperse your internal energy!" After saying that, Li Heng completely dissipated all of his immense internal energy.

After the immense internal energy dissipated within his body, Li Heng found that his body still had that warm feeling, as if it had been gently nourished.

He could feel that the purity of his internal energy had increased significantly again.

"Huh, it can even be improved?" Li Heng was overjoyed.

In the past, whether it was dispersing one's cultivation at the first-grade level or at the grandmaster level, dispersing one's cultivation ten times would result in improvement each time, but after ten times, dispersing one's cultivation would result in no improvement at all.

Now, after dispersing his power for the eleventh time, Li Heng has found that he is still improving. It seems that the limit of dispersing power for a Grandmaster is higher than that of a First-Rank or Grandmaster.

"Any improvement is good. My greatest advantage is my unlimited lifespan. I'll continue cultivating!"

Knowing that he could continue to improve, Li Heng once again immersed himself in cultivation.

......

Two years later.

Inside the cave, Li Heng once again cultivated to the peak of the Grandmaster level.

This time, however, no powerful fluctuations emanated from his body. Judging from his appearance alone, Li Heng was just an ordinary mortal with no strength to even kill a chicken.

The body's energy flows smoothly and harmoniously, the spirit and body are in harmony, and the energy and blood are integrated.

Li Heng had reached a state of perfection, which Buddhism calls "non-leaking" and Taoism calls "flawless".

Round and bright, this is the ultimate manifestation of the innate realm.

The ultimate perfection of the innate realm is something countless martial artists dream of, but no martial artist has ever been able to cultivate to this level.

Because this is only theoretical, an interesting anecdote written into myths and legends. The patriarchs of Buddhism and Taoism in myths and legends have all reached this state.

"This time, I can feel that I have reached the ultimate perfection in the Innate Realm, and I no longer need to disperse my energy and start over!" Li Heng murmured to himself.

Reaching such a perfect state of cultivation was like a complete transformation for him. It wasn't just a matter of physical strength, but also a matter of spiritual level. Li Heng felt that his eyesight, perception, memory, and many other aspects had been greatly enhanced.

It's similar to the state of perfect wisdom in Buddhism. Of course, it's only the perfection of the innate realm. There's still a very, very long way to go before reaching true perfection.

Suddenly, Li Heng discovered that he could see inside his body, but it was very blurry.

He could see that the internal energy in his dantian had already formed a liquid state. Generally, the internal energy of a grandmaster is in a gaseous state. Li Heng knew that this was a sign of extremely pure internal energy.

Above the dantian, five wooden roots of different colors floated.

The five wood roots are colored as follows: green, yellow, red, white, and black.

Li Heng could feel that the liquid internal energy in his dantian was constantly nourishing the five wooden roots above him.

Suddenly, the five wooden roots above emitted a dazzling light, and a suction force came from the five wooden roots.

Outside Li Heng's body, in the air, wisps of very, very faint five-colored mist kept appearing. These five-colored mists seemed to sense the suction force from the five wooden roots and entered Li Heng's body one after another, and were eventually absorbed by the five wooden roots.

This action lasted for an hour.

Ultimately, the five wooden roots seemed to be separating and filtering the five-colored mist, expelling the useless gases directly and leaving only the gases that were useful to them.

Soon after, the five wooden roots underwent an even more astonishing change. Each of the five roots released a wisp of pure gas, and the color of these five wisps of gas matched the color of the five wooden roots from which they came.

These five wisps of gas arrived in the dantian and came into contact with the liquid internal force within it.

When the liquid internal force came into contact with these five wisps of gas, it was like ice melting rapidly when it came into contact with a red-hot furnace.

Soon, the liquid internal force in Li Heng's dantian was completely dissolved by the five strands of gas, and the five strands of pure gas of different colors each occupied a corner in Li Heng's dantian.

Li Heng was utterly horrified. All the internal energy he had painstakingly cultivated had been destroyed by these five strands of gas.

What was the origin of these five wisps of gas? How could they so quickly annihilate his liquid internal energy?

What's even more infuriating is that these five wisps of energy usurped his position and completely occupied his dantian.

And what about these five wooden roots?

Li Heng felt very confused and urgently needed someone to help him answer his questions.
