In the Demon Suppression Division, the Iron-Cutting Sword Technique is perfected

Gu Cheng chuckled and shook his head.

With a flick of his wrist, he put the innate demon core given by Xu Zhendong into the storage bag together with the token.

With his fingertips, he lightly touched his face, and his ordinary appearance was like a mask removed, revealing his handsome and extraordinary true face underneath.

Gu Cheng flew to the corpse of the fox demon, skillfully dug out the demon core in its body, and put it away together with the storage magic tool.

After doing all this, he pinched his fingers with one hand and operated the magical power "Blood Furnace".

Scarlet evil spirit surged out of his body, wrapping the corpses of the two demon beasts in it, and the blood and qi rolled, as terrifying as a purgatory furnace.

Gu Cheng closed his eyes and floated in the air, greedily absorbing the energy extracted from the corpses of the two demon beasts.

Strands of blood evil spirit penetrated into his body, raging in his meridians, and were finally absorbed by his flesh.

If the second son Xu, who hated evil as much as his own enemies, had seen such an evil and horrifying scene, he would have jumped up and down in shock, shouting out evil and perverse ways.

Time passed.

The two huge corpses of the monsters shrank at a speed visible to the naked eye.

When the last wisp of blood was devoured, the two corpses disappeared completely, leaving only two groups of blood mist that had not yet dissipated, emitting a faint smell of blood in the air.

Gu Cheng took a deep breath, calmed the surging blood in his body, and the blood in his eyes surged.

"These two beasts are far inferior to that thousand-year-old tree monster."

He whispered to himself, recalling the scene when he devoured the thousand-year-old tree monster, and a trace of doubt rose in his heart.

Perhaps, the life essence of plants is easier to be absorbed by the human body?

This thought flashed through Gu Cheng's mind, and then he did not delve into it.

He sat cross-legged directly on the lake, infused his life essence, and began to refine the huge energy he absorbed.

With the previous experience, the refining process this time seemed to be unusually smooth.

…

[Year 243: You will completely refine the energy you swallowed and transform it into extremely pure blood evil power.

Driven by this power, your blood knife has made rapid progress and vaguely touched a higher level. ]

[Year 314: After years of hard training, you will absorb the refined blood evil power and completely integrate it into your body, and the strength of your body has been qualitatively improved. ]

[Physical training: Innate sixth level]

[Remaining lifespan: 4,694 years]

"Hu——"

Gu Cheng slowly exhaled a breath of turbid air, and the white-like energy crossed the lake, leaving a clear scratch.

He stretched his muscles and bones, feeling the endless power surging in his body.

A dignified momentum emanated from his body, shaking the lake surface, and as the water vapor evaporated, circles of ripples spread out and lasted for a long time.

"The flesh and blood of two great innate demons only allowed me to improve my cultivation by one level?"

Gu Cheng glanced at the record on the panel and frowned slightly.

The innate realm is a realm with a huge span, which can be said to be a new level with each step.

Entering the sixth level of the innate realm is already the threshold of the high-level innate realm, and the subsequent cultivation path will naturally become more difficult.

If you want to break through faster, you can only devour more flesh and blood of the great innate demons!

After dealing with these trivial matters.

Gu Cheng continued his treasure hunt.

He soared into the air, flew along the shore of the Falling Star Lake, and finally stopped in front of a waterfall like a waterfall.

The water poured down from the nearby cliffs, like a silver dragon rushing into the lake, and the deafening sound echoed in the mountains and forests.

The mist behind the waterfall was filled with water, forming a natural barrier that blocked all sights.

Gu Cheng hovered in front of the waterfall and used his divine sense to carefully explore, but found nothing.

If it weren't for the fact that Feng Sanshi's residual soul would never lie, he would have suspected that he was fooled by the horse-faced Taoist priest.

Gu Cheng took a deep breath and urged his divine sense again, like a pair of invisible giant hands, suddenly splitting the rushing waterfall in two.

The water curtain suddenly parted, and a deep and dark cave entrance suddenly appeared in front of him!

"Got it!" Gu Cheng's eyes suddenly lit up.

No wonder the fox demon and the fish demon set up an ambush in the Falling Star Lake for many days, but did not find the abnormality here. The concealment method of this Qinglian Venerable is indeed extraordinary!

If it weren't for the coincidence that he came here, who would have thought that there was another world behind this waterfall?

Gu Cheng no longer hesitated, his figure flashed, and he flew straight into the cave.

The space inside the cave is long and narrow, and a long stone staircase winds down.

With every step, the candlesticks on both sides will light up an illusory flame, lighting the way ahead.

An ancient and mysterious atmosphere came to my face, giving me the excitement of tomb raiding and treasure hunting.

After walking for an unknown period of time, Gu Cheng suddenly saw a wide underground space.

This was a huge martial arts arena, with ancient bluestone slabs on the ground. After years of baptism, it still looked very beautiful.Smooth as a mirror.

The venue is surrounded by a circle of stone statues of various shapes, the smallest of which is about ten feet tall. They all have animal heads and human bodies, armed with weapons, and are lifelike, as if a silent army is guarding this place.

In the center of all the stone statues, there is a human sculpture sitting cross-legged.

This sculpture is several times taller than the other stone statues. Although its face cannot be seen clearly, its awe-inspiring and terrifying momentum is like a sharp sword piercing the sky, suppressing the momentum of all the surrounding stone statues.

"Why does Venerable Qinglian make so many stone statues?"

"Is he also a figurine maniac like Qin Shihuang?"

Gu Cheng strolled in the empty underground martial arts field, looking at these lifelike stone statues, and was very puzzled.

According to legend, Venerable Qinglian disappeared after a fierce battle with the Dragon King, and everyone thought he was seriously injured and died.

In this case, he was probably at the end of his strength when he built this heritage treasure house.

Rather than being a heritage treasure house, this underground martial arts arena is more like a [tomb] tailor-made for Venerable Qinglian.

Gu Cheng walked around the entire martial arts arena, but did not find any treasures worth noting.

According to Feng Sanshi's residual image, those valuable things had already been taken away by him.

And the most precious things were all hidden in the inner layer of this treasure house.

"So, where is the entrance to the inner layer?"

Gu Cheng frowned slightly, his eyes swept across the empty martial arts arena, and finally stopped at one edge.

There was an ancient piano table, with nothing on it, only a soft cushion lying there quietly.

Gu Cheng's heart moved, and he jumped into the martial arts arena, sat cross-legged on the cushion, and placed the ancient piano named "Dead Wood Dragon Song" on the piano table.

The slender fingers gently plucked the strings of the zither, and a clear sound suddenly sounded, resounding throughout the palace like a dragon's roar, breaking the long silence here.

"Zheng——"

The unique sound of the withered wood dragon's roar seemed to contain some kind of magic, echoing in the empty martial arts field, and never stopped for a long time.

As the sound of the zither changed, the surrounding stone statues seemed to be given life, and they trembled slightly, and strange light flashed in their originally empty eyes.

Gu Cheng was startled and quickly stopped playing. As the sound of the zither stopped, the stone statues also returned to calm.

"Interesting..."

Gu Cheng's mouth corners rose slightly, as if he understood something, and then plucked the strings again.

This time, the sound of the zither was passionate and generous, as if thousands of troops were galloping in his ears, and the sound of killing came one after another.

As the sound of the zither became more and more passionate, the reaction of the stone statues became more and more intense.

Finally, a stone statue with a tiger head and a human body cracked.

A ray of light flew out and transformed into a tiger demon servant holding a ghost-head sword, roaring and rushing towards Gu Cheng!
