The water on the surface of the deep pool is like a hot spring, and it is very comfortable for people to soak in it, but the more Ye Xingchen dives into the bottom of the pool, the stronger the air pressure, and the water in the pool is getting colder and colder, and the temperature is plummeting sharply.

Ye Xingchen felt that it had suddenly come from summer to winter, and there were wisps of white air flowing in the pool water, and he wrapped the wisps of white air with his true qi, suspended in front of him, with touch, he felt a trace of cold qi, and invaded his arm along the palm of his hand.

The Great Sun True Qi in his body worked slightly, dissolving the cold qi.

Ye Xingchen was a little surprised, such a performance would appear at the bottom of the deep pool, which made him curious in his heart, and he couldn't help but explore downward.

According to the normal situation, there is a spiritual spring at the bottom of the Tan, and it is impossible to have extreme changes, but at this moment, there is a cold aura.

Ye Xingchen continued to dive downward, and after about a quarter of an hour, he dived down for three hundred zhang, and at this moment, the air pressure around him was very strong, and the pools of water in all directions were squeezing towards him, trying to crush his body.

Fortunately, his physical body was strong, and the sixteen acupuncture points were opened, and the essence qi penetrated the meridians of his body, flowing in the flesh and blood, eliminating that pressure.

Ye Xingchen looked at Tan Di, except for the water flow, he couldn't see any scenery, not even fish and other underwater creatures, and it seemed that there was still a long distance from Tan Di.

He dived down again, and the cold aura became more and more intense, like white glass dragons, swimming in the water.

Ye Xingchen was surprised to find that there were traces of knives and axes on the Tan Wall, proving that this deep pool with no visible bottom was not naturally formed, but artificially chiseled by the day after tomorrow.

He has touched the excavation marks on the Tan wall, which is very rough and ancient, at least tens of thousands of years old, and can be traced back to the Middle Ages.

From 5,000 years ago to 10,000 years ago, it was the ancient period, from 10,000 years ago to 100,000 years ago, it was the Middle Ages, and from 100,000 years ago to a million years ago, it was the ancient period.

The excavation of Tan Bi has been at least 10,000 years, and it is very likely that the warriors of the Middle Ages opened it up for some reason.

Ye Xingchen continued to dive forward for three thousand zhang, the water pressure around him was stronger, Ye Xingchen's body was a little unable to support it, and the cold aura around him became more and more vigorous, as if he had come to an iceberg for ten thousand years, it was very cold.

The endless frost qi froze the true qi in his body, and it slowed down.

Fortunately, he cultivated the Great Sun True Qi and the Taiyin True Qi, and he operated the Taiyin True Qi and absorbed these Yin and Cold Qi, not only did his body not be damaged, but also made the Taiyin True Qi grow stronger and more condensed.

In the end, Ye Xingchen dived into the deep pool to a depth of about 5,000 zhang before finally reaching the end.

On the stone wall at the bottom of the Tan, he found a huge stone door, and the cold air emanated from the crack in the stone door.

Tens of thousands of years have passed, and the spirit pattern seal on the stone gate has become very weak, which is why the cold qi and spiritual energy have come out of the stone gate.

Ye Xingchen tried, he pushed hard, and the stone gate stood still.

When there was a lot of pressure under the water, he couldn't exert his strength, and when he had no choice, he thought that the Eye of Luck could see through the shortcomings of all things, so he used the Eye of Luck to find out the weak point of the Shimen Spirit Pattern Seal.

About a moment later, Ye Xingchen saw that in the corner of the stone gate, the power of the spirit pattern was running obscurely, and the luster was dim.

"Bang!"

Ye Xingchen clenched his fists and punched at that corner, the spirit pattern seal on the stone door stopped working for a while, and he took this opportunity to push open the stone door and enter inside.

The inside of the stone gate is a very dry and tidy space, and the walls are carved with pictures that record the events of the past.

Ye Xingchen's eyes showed a golden light, and even in the dim environment, he could still see clearly.

The first picture records the scenes of many powerful warriors fighting with a group of evil creatures, those terrifying and evil creatures, full of killing and destruction, those warriors are not low, and they flee in defeat.

In the second picture, some defeated warriors fled all the way to the land of Taixu, entered the Tianwu Mountains, found a valley, dug out a deep pool, and created the space world in the stone gate.

In the third picture, the surviving warrior lived in the Shimen space at the bottom of the deep pool for a while, and a strong man returned from going out, telling the news of the terrifying creatures chasing him, and everyone packed up their belongings and prepared to leave the space under the deep pool.

This is the end of the three drawings, and there is a fourth drawing, which is not finished, but it is not drawn because the men are leaving.

Ye Xingchen walked towards the depths of space, about two miles away, when suddenly the yin wind roared, and the yin wind, like a sharp sword, blew his skin painfully.

Ye Xingchen ran the Great Sun Gold Pattern, and a thin layer of light appeared on the surface of his body, isolating the yin wind from the outside.

He had walked another three miles, and there seemed to be a strange movement in the darkness ahead of him, when suddenly a huge creature attacked him in the darkness.

"Roar!"

With an angry roar, the mountain wall trembled, stone powder fell, and a humanoid creature with nails half a foot long and a cold light flashed, grabbing Ye Xingchen like a sharp blade.

Ye Xingchen's body moved, avoiding the blow, and with a snort, the creature's hand grabbed on the stone wall, and the stone wall blessed with spirit patterns was grabbed out of a large crack.

Ye Xingchen's fingers flicked continuously, and sword light shot out like meteors, illuminating this space, hitting the body of the creature, making a "ding" sound, as if colliding on metal.

Only then did he see the true face of this creature, this was an extremely powerful corpse demon, with a tall body, a hideous face, and its whole body was protected by black scales, and on his forehead, there was even a single horn, which was as black as ink.

"Roar!"

This huge corpse demon was very angry, and roared angrily, I don't know if it was angry or calling for its companions.

Ye Xingchen's body flashed, and a sword light slashed, piercing the head of the corpse demon, no matter how strong the corpse demon was, he couldn't resist the sword qi under the blessing of his sword intent, and the corpse demon didn't dare to roar angrily, and fell to the ground and died.

Ye Xingchen stepped forward, looked at the corpse demon carefully, and found that the clothes he was wearing were not very ancient, about thousands of years ago.

"Could it be that the original group of people is not finished, there are still some people left, but why did he die thousands of years ago and turn into a corpse demon?" Ye Xingchen was puzzled in his heart and continued to walk deeper.

Halfway through, he encountered several more corpse demons, all of whom he killed one by one.

Ye Xingchen walked a distance of ten miles in the space again, it was hard for him to imagine that those people could carve out such a large space under the ground, but when he recalled those three pictures, it was not surprising that the strength of those group of martial artists was very strong, and it definitely surpassed the three realms of the heavenly rank.

Ahead, there was a sudden light, and the originally dark space receded, ushering in light, and at the same time, the cold air also dissipated, and there was a warmth emanating.

Ye Xingchen walked forward, about a mile away, he saw that not far ahead, there was a huge ancient building, magnificent and magnificent, like an ancient sacred mountain, exuding crystal light.
