"Crash!" The sound of water affected Gu Fei's mental state, and he quickly hid behind a large rock, carefully peeking his head out from behind the rock, looking towards the direction of the sound.

It had a black body, white belly, and green eyes. The black snake that came out of the pond beside the pile of bones closely matched the characteristics of the Black Water Serpent that was recorded in the《 Record of the Demonic Beast》.

"Hiss!" The black serpent, whose body was as thick as a bucket, suddenly hissed. "Peng!" A loud sound was heard as it jumped out of the water.

In the dim light, Gu Fei could see clearly that the profound snake was over fifteen meters long. On the snake's body, there was a palm-sized scale armor.

A pair of frightening dark green eyes swept in all directions, and the snake's tongue constantly bit into the mouth of the blood-red plate that was filled with barbed sharp teeth.

It was obvious that this Black Water Serpent had already discovered that its prey was gone, causing it to be extremely furious. Its thick body continued to slap the cold and hard ground, and the black rocks that were as hard as refined iron s, to the point of splashing debris, under the assault of its body that was like a divine whip, started to explode one after another.

Immense sounds of impact and the rolling of stones rang out in quick succession. The mountain-like bones were flattened by the young Black Water Serpent in an instant, and a strong stench immediately filled the cave.

The black rocks that were as hard as steel were all smashed into pieces by the Black Water Serpent that was still in its infancy. The strength of this black serpent was immense, and the toughness of its body was evident.

When he was not hungry, he would often have the habit of storing his prey. This young Black Water Serpent had already swallowed a huge Jadefallen Carp, which was why Gu Fei was able to escape disaster.

"This is bad!" Gu Fei hid his body behind the huge boulder, and did not dare to look anymore.

Because that Black Water Serpent seemed to have sensed that something was amiss over here. A pair of eyes that was filled with a frightening light, suddenly turned in Gu Fei's direction.

"Whoosh!" With a sound, a black figure, like a huge sharp arrow, drew a long path in the air, and came to a stop ten meters away from the huge boulder that Gu Fei was hiding in.

The Black Water Serpent seemed to be afraid of something and did not dare to approach.

Gu Fei who was behind the boulder felt a fishy wind blow past the boulder, and then, a terrifying and fearsome might surged over, causing him to tremble in fear.

The bitter and bitter killing intent was very, very close to him, and Gu Fei felt an extreme sense of danger. All the muscles on his body tensed up, and his forehead started sweating.

"Hiss!" The Black Water Serpent cried out repeatedly, as though it was unwilling to give up. It stayed in front of the boulder for a while, then retreated.

The extremely nervous Gu Fei, could feel the dangerous aura that caused his heart to palpitate leaving and the sound of water flowing once again, had actually left the cave.

"What is it afraid of?" Gu Fei was baffled and then his whole body relaxed as he sat on the ground. It was only then that he realized he was covered in cold sweat.

The suppressive feeling the Black Water Serpent gave Gu Fei was simply too strong. After the Black Water Serpent left, he heaved a sigh of relief, but at the same time, he was also greatly surprised.

"Could it be …" Gu Fei looked at the Indestructible Body that stood tall like a mountain in front of him. Is the Black Water Serpent afraid of the Unrivaled Expert?

Seemingly, only with this reason could he understand why the Black Water Serpent retreated.

Even though he was dead, his body was indestructible, and he had an imposing manner that lasted for a long time. The domineering might of the Unrivaled Expert was actually able to intimidate Black Water Serpent? This caused Gu Fei to be in disbelief.

Of course, this might have something to do with the young Black Water Serpent.

No matter what, he was in a dangerous place and his life was at risk. This was Gu Fei's current situation. In this ice-cold and dark cave, there was a Demonic Beast at the side that could threaten Gu Fei's life at any time, spying on him.

No matter the time, having powerful strength was the most important. Being brought here by the Black Water Serpent from the Cold Pool of Green Water, the endless water pressure nearly tore his body apart. The moment the profound snake wrapped around his body, it also caused his muscles and bones to tremble.

Furthermore, in the courtyard where he lived in the sect, he had also suffered an internal injury after being hit on the back by Wang Yuanzhi's Five Tripod Mountain technique.

The current Gu Fei could be said to be suffering from typhoid fever. When his body relaxed, he actually felt a little exhausted.

He placed the two pieces of ancient sword on the ground beside him, and just like that, under the big rock, before the Indestructible Body, he sat cross-legged, channeling the Ancient Body Refining Art to recover his strength.

The Black Water Serpent did not dare to approach the middle-aged ranker who had passed away in the middle of the cave. This allowed Gu Fei to feel more or less at ease. Circulating his cultivation technique, a suction force gradually appeared in his dantian, absorbing the surrounding Spiritual Qi of Heaven and Earth and spreading it into his muscles and bones.

Because the meridians throughout the body had yet to be fully opened, the process of the tempering of the body by the nature's spiritual energy was incomparably slow. Just as Gu Fei was immersed in cultivation, the yin yang fish jade pendant on his chest started to emit a faint spiritual light. The yin yang energy and yang energy on the jade pendant started to revolve and a Taiji Yin-Yang Diagram appeared.

The moment the Taiji Yin-Yang Diagram appeared, the natural spirit energy within the cave trembled, and quickly rushed towards the Taiji Yin-Yang Diagram.

The speed at which Gu Fei absorbed the spirit energy immediately increased exponentially. The spirit energy of heaven and earth that was gathered into the Taiji Yin-Yang Diagram formed from yin and yang energy was absorbed into Gu Fei's dantian.

In just a short while, Gu Fei felt a swelling pain from his Dantian, and the Tai Chi diagram became clearer and clearer, gradually showing signs of becoming corporeal. The Vital Energy of Heaven And Earth s that came from all directions started surging like a raging sea.

This cave under the Cold Pool of Green Water contained astonishing spirit energy of heaven and earth.

A dazzling Light Sphere appeared from within Gu Fei's dantian. It was the result of the various Vital Energy of Heaven And Earth's highly condensed form within the cave.

The Vital Energy of Heaven And Earth s in the cave were all gathered up by the Taiji Yin-Yang Diagram in an instant, and then, the countless paths that led to who knows where started to emit waves of spirit energy.

The vast amount of spirit energy poured into Gu Fei's body, and the energy Light Sphere in his dantian became even more dazzling, emitting a spirit light that illuminated the entire cave.

"Crash!" With the sound of water, a black shadow rushed out from one of the pools. With a dark green fierce eyes and a ferocious beast's head, it was the young Black Water Serpent.

Within the Black Water Serpent's large eyes that were flickering with a fierce light, there was actually a hint of fear. Like a bolt of lightning, it flew a distance of three to four hundred meters and approached them.

He wanted to rush forward and swallow this prey into his stomach, but he didn't dare. He could only raise his head and scream, not daring to move forward.

But the Black Water Serpent did not have the intention to retreat, it actually retreated four to five meters away, and stared straight at Gu Fei, the berserk and fiendish Qi, spreading out mightily.

Even the meditating Gu Fei seemed to have detected something was amiss at this time. His eyelids moved a little, but he still did not open his tightly shut eyes in the end.

Endless amounts of spirit energy flowed through the Taiji Yin-Yang Diagram into Gu Fei's body. Not only did it heal the injuries on his body, even the cultivation screen that he had been unable to break through for a long time, started to vibrate at this time.

The twelve energy channels in Gu Fei's body were continuously being broken through by the unending flow of the nature's spirit energy from his dantian.

Inside the cave, there were countless caves that seemed to be covered by a layer of water. The Vital Energy of Heaven And Earth s that were sucked over did not seem to be exhausted, as if they were endless.

After four hours, Gu Fei's internal injuries were completely healed, the blood in his body was forced out of his body through his pores, all twelve meridians were opened, and his cultivation rose rapidly. From the third sky to the fourth heaven, and from the fourth heaven to the first heaven, Fifth Layer, I was awakened with a rise in momentum that still did not stop.
