The lake is cold and biting, but fortunately, Li Han is now strong, far beyond ordinary people, but he is not afraid of the cold.

In addition, he has achieved the meaning of the common source of water and fire, and he has even been at the bottom of the sea, so he is naturally not afraid of difficulties at the bottom of this lake.

The further down you go, the more difficult it becomes, and the water seems to be divided into several layers, containing natural mysteries, washing each other, and the further down you go, the stronger the repulsion, as if you don't want outsiders to enter. Li Han runs the water and fire to resist repulsion, so that it can continue to decline slowly.

At this time, he had a realization in his heart, if he hadn't broken through the Fadan realm, he was afraid that he wouldn't even be able to reach half of the depth of the lake.

It seems that this is the prohibition in the mouth of the Earth Compassion God Monk, and sure enough, the illegal Dan realm cannot be entered.

However, for the severe cold, the sense of oppression is a little stronger, and as long as the exercises are operated, it is still very difficult to continue to go deep towards the bottom of the lake.

Slowly, with the soft sound of "wave", it seemed to jump out of some circle, and the sense of oppression suddenly subsided, and he came to a strange world.

Here, it is obviously under the water, but there is no trace of water around the body. Overhead, a blue curtain of light stretched overhead, seemingly isolating the place, forming an underwater world.

Overhead, a school of fish swam away, aquatic plants overgrow, and in the place, the white sand is paved, the pothos is shaded, and not far ahead, there is a dark hole made of bricks and stones.

"Enter!"

The strong cold skills are bold and bold, so naturally there is no danger. And since he already knew that this place was the retreat place of Master Tianxuan, he came here for this, how could he retreat halfway?

There is a stone door at the entrance of the cave, and above the stone door, there is a concave surface of a Buddha statue the size of a palm, which seems to need something embedded to open.

Li Han's heart moved, and he thought of what the Earth Compassion Monk said that he needed a Fanyin Temple token to enter, and he suddenly understood. With a wave of his palm, the golden light in his palm shone brightly, and the golden Buddha token given by the earth compassion monk on his deathbed suddenly appeared in his palm.

He held the token in his hand and slowly sent it forward, and immediately attached it to the concave surface of the Buddha statue on the stone door, and there was no trace left.

The convex surface of the Buddha statue on the token and the concave surface of the Buddha statue on the stone gate fit together to form a key-like effect.

Suddenly, there was a soft "click", and the stone gate bloomed with a dazzling golden light, and after the golden light, the dust fell, and the long-sealed stone gate slowly opened to both sides, revealing a dark passage.

Li Han lifted a trace of his mind slightly, ran the five elements and ten directions, and his body was shrouded in a layer of bright yellow light, and slowly entered forward.

The stone path is dark and gloomy, and I don't know where it leads, long and narrow, cold and walking and stopping, the dark blue light in the eyes is constantly flashing, but it is the farsightedness technique that has opened the magic pupil.

Finally, a light appeared in front of him, and his body moved, and Li Han suddenly appeared in a huge underground cave.

Above the cave, there was actually a sprinkling of skylight, but in the middle of the cave, a huge stone tablet that was even taller, as if it was straight into the sky, blocked in front of the cold cold.

Other than that, in the whole cave, there is nothing else at a glance.

"What about Master Tianxuan?"

Li Han was strange, frowning and looking, but he couldn't find any trace of the people living here.

"Could it be that there is another mystery here?"

Thinking of this, he looked around for a moment, and finally settled on the giant stone tablet.

The stele is as smooth as jade, and I don't know how it was transported to the bottom of this lake, or if it stands here naturally. On the stone stele, there are strange symbols one after another, shaped like flames, connected into a vast sea of stars. But each one is written with the same word 'Buddha', but the appearance is different.

"Flame Buddha?"

Li Han frowned, he had heard of this kind of writing in ancient times, all of which were Buddhist scriptures written with flame symbols, but those words were written scriptures, but here, they were all the same word, which seemed a little weird.

"Could it be that this is the place where Master Tianxuan attained enlightenment? These flame Buddhist texts were all engraved by him?"

Li Han's heart moved, and he figured this out, because the only person who can have anything to do with the Buddha here is the former abbot of Fanyin Temple, the first person in the world, 'Master Tianxuan'.

It's just that why is he nowhere to be seen, could it be that he has really broken through successfully and has already left?

Li Han frowned, a little not quite believing his assertion.

Because obviously, if he had really succeeded in breaking through, he would have returned to Fanyin Temple a long time ago, even if he didn't return to Fanyin Temple, as long as he was in the True Dragon Continent, it would be impossible to sit and watch Fanyin Temple be wiped out, and he wouldn't appear.

And if he is not in the Fanyin Temple, or has already left the True Dragon Continent, at least before leaving, he should also say hello to the juniors of the sect. As the head of a sect like him, he is not like a person who will say goodbye and go his own way.

Therefore, Li Han concluded that he should still be in this underground space, either he has not succeeded and continues to break through in a secret place, or he has failed to break through and completely sat down.

"Just, where the hell is it? Could it be that there are other entrances here?"

Li Han also felt helpless for a while, so he could only walk around, touching east and west to see if there was any mechanism. However, the surroundings were clear at a glance, there was nothing special at all, and Li Han did not find any passage to other places.

Eventually, Li Han returned to the giant stone monument.

In this karst cave, if you want to say that it is abnormal, and the only thing that is special, it can even be said to be very special, is only this huge stone tablet with countless flame Buddhist inscriptions carved on it.

It is precisely because of this stone tablet that Li Han is more convinced, Master Tianxuan must have been here, and now it should still be somewhere underground, but Li Han can't find the entrance and exit for a while.

But since people are here, there is always a trace to be found, as long as you find the mechanism that is opened, there is no doubt that all the mystery will be revealed.

Li Han's gaze fell on those strange Buddhist texts that seemed to be leaping flames.

Perhaps, that hidden mechanism fell on these seemingly inconspicuous and unrelated Buddhist texts.

So, Li Han didn't go anywhere, just in front of the stele, sitting cross-legged, staring at the countless Buddhist texts on the stele, imagining how Master Tianxuan understood the Tao of Heaven and Man here and profoundly the Buddha's teachings.

However, he is not a Buddhist cultivator after all, these Buddhist texts are still fresh at first glance, and the more they are read, the more boring they become, after all, the whole text is the same word, even if the shapes are strange and varied, Li Han can't see anything useful.

"Hey!"

Eventually, Li Han let out a long sigh and closed his eyes, confirming that he was not the material. On the contrary, after looking at it for a long time, my eyes are extremely sour, and I am about to cry, which is the consequence of staring at the same thing for a long time.

However, although he closed his eyes, in his mind, the thousands of Buddhist texts he had just seen were still emerging in his mind, and when he opened his eyes just now, his attention was all on the stone tablet in front of him, and he didn't feel it.

"Huh, what is this?"

Li Han was surprised, suddenly, and the mutation regenerated.

In his storage ring, a piece of red copper, suddenly emitting a faint warmth, automatically flew out of the ring, suspended in front of Li Han, and kept rotating.

On the red copper plate, a dazzling golden light shone, corresponding to the flame Buddhist inscription on the stone tablet. On top of the copper plate, the little monk began to move again, and his hands pinched out a strange seal and waved it forward.

"Boom!"

Suddenly, at the moment when the little monk of the copper sheet made the seal, the countless flame Buddhist texts on the giant stone tablet suddenly lit up at the same time, and then burst out with a dazzling firelight, and in the firelight, the stone tablet slowly cracked, revealing a small hole.

Li Han was stunned, and then he was overjoyed, although he didn't understand what was happening, but he still didn't hesitate, his body was vertical, he grabbed the copper piece, and jumped into the mouth of the dark hole.
