Urban Cultivation of Immortal Emperor Invincible

The air wave was like an extremely sharp blade, which forcibly opened up an extremely wide passage in the pile of rocks.

The passage was so wide that it seemed to be able to accommodate thousands of troops, and the stone walls on both sides became as smooth as mirrors under the impact of the air waves.

The smoke and dust gradually dissipated like thick fog. At the end of the passage, a mysterious blue light shone like a lighthouse in the dark night, attracting the attention of Ye Chen and Yan Wang.

The King of Hell opened his eyes wide, filled with astonishment and disbelief.

He had been in the underworld for many years and thought he had heard of all the rare treasures there.

But the mysterious treasure hidden under the Yinshan Mountain before him was far beyond his understanding.

His originally dignified and stern face was now filled with shock, his lips trembled slightly, and he seemed to want to say something, but his throat was choked by this sudden surprise.

Ye Chen's eyes were also filled with deep shock, but his movements did not slow down at all.

The figure was as fast as lightning. In a flash, he crossed the long passage and came to the front of the mysterious object.

His heartbeat accelerated involuntarily, and an unprecedented excitement surged in his heart.

Upon seeing this, the King of Hell immediately came to his senses and followed closely behind like a ghost.

In front of them was a huge seal that was extremely simple and ancient, like a divine artifact from ancient mythology.

This seal is three feet square, and every inch of it exudes an ancient and mysterious atmosphere.

The texture of the seal is like gold but not gold, like jade but not jade. The surface has a mottled texture that comes from the accumulation of years, as if countless ancient stories are engraved on it.

It is covered with intricate patterns that appear to be either naturally generated or carefully carved.

The lines are winding like ancient vines; some are as thick as arms and deeply sunken into the surface of the seal.

There seemed to be a mysterious power flowing inside, and occasionally a faint light flashed, as if an elf hidden deep inside was spying on the outside world.

Some of the lines are as thin as hair, but clearly visible. They are intertwined and entangled with each other, forming mysterious patterns.

Above the seal, there is a black dragon coiled.

The black dragon's body was agile and powerful, and its scales were like pieces of exquisite black armor, each of which sparkled with a cold luster, as if one would be cut by its sharpness if touched lightly.

The black dragon's eyes were like two bright stars, deep and majestic, emitting a terrifying light.

It opened its bloody mouth, revealing its sharp fangs, as if it was roaring. The roar seemed to come from time and space, shocking people.

The dragon's whiskers are like dancing snakes, swaying slightly in the air, and each whisker seems to contain mysterious power.

The entire black dragon was lifelike, and it felt like it would break free from the seal and soar into the sky in the next moment. The divine power it emanated made the air around it become heavy.

On the front of the seal, there is a word "Xuan" carved.

This word seems to have a kind of magic, and every stroke seems to contain the mystery of the universe.

The lines of the characters are strong and powerful, yet have a flowing beauty, as if they were engraved by a peerless master with supreme power.

There seems to be a faint halo flowing around the word "Xuan", and in the halo there is the illusion of twinkling stars and flowing galaxies, which makes people fall into reverie of the endless mysteries of the universe.

On the back of the seal, the word "Yin" is engraved.

This word exudes a gloomy and cold aura. The color of the word is as deep as ink, like an endless dark abyss.

The strokes of the word "yin" are like black lightning, seeming to release wisps of yin energy around.

Under the cover of this yin energy, the temperature around suddenly dropped, making people feel as if they were in the Nine Nether Hell, and their souls couldn't help but tremble.

The other two sides of the seal are covered with mysterious runes.

These runes are densely packed, of varying sizes and shapes.

Some runes are like ancient totems, containing mysterious powers from tribal times.

Some runes are like the arrangement patterns of stars in the universe, exuding a vast and boundless aura.

Some runes look like the marks of mysterious creatures, carrying a primitive and brutal power.

A mysterious light flickered above each rune, and the lights intertwined together to form a colorful light curtain.

There seemed to be countless mysterious forces surging and colliding in the light curtain, like the center of a vortex of mysterious power.

At the very bottom of the seal, there is a huge word "Soul" carved.

The word "soul" reveals an indescribable majesty, as if it is the master of all souls in the world.

Its strokes are thick and heavy, as if they were forged with the power of countless souls.

There is a layer of soul power surrounding the word "soul", which is sometimes visible and sometimes invisible, and that soul power takes various forms.

There are hideous and terrifying souls of evil spirits, there are pure and kind souls of angels, and there are also souls of creatures of various shapes.

They circled and struggled around the word "soul", as if they were suppressed by the word "soul", making people feel that this seal possessed the terrifying power to suppress all souls in the world.

Even beings like Ye Chen and Yan Wang, who have extremely powerful souls, couldn't help but feel a palpitation when facing this mysterious seal.

Ye Chen only felt that his soul had turned into a small boat in front of the seal, drifting unsteadily in the sea with strong winds and huge waves, and could be swallowed up by the surging power at any time.

Fine beads of sweat oozed from his forehead, his hands trembled slightly, and his eyes were filled with awe of the power of the seal and irrepressible curiosity.

The King of Hell was not much better off. His originally powerful soul seemed to be shrouded by an invisible shadow.

He could feel the fear deep in his soul spreading, a fear of an unknown powerful force that came from the origin of his soul.

His face turned as pale as paper, and his legs unconsciously became slightly weak. He felt the power of this force was so great, and felt that once the power contained in this seal exploded, he would probably be reduced to ashes in an instant.

Ye Chen was also extremely happy at this moment. A smile blossomed on his determined face, like the light of dawn tearing through the dark clouds.

His intuition was like an accurate key. After countless searches, he finally opened the right door.

There really was a secret here, a feeling deep in his bones, as if a mysterious voice was whispering deep in his soul.

Just now, he used the Eye of Heaven.

This is not an ordinary skill, it is a magical ability that can see through the secrets of all things in the world.

The moment he opened the Eye of Heaven, the world around him seemed to be shrouded in a layer of faint colorful light.

The light extended out like a silk thread, passing through every inch of land and every rock of Yinshan Mountain, presenting everything of Yinshan Mountain to his perception without reservation.

Under the X-ray-like perspective, the center of the mountain attracted his attention like a singularity of the universe.

There, he found this big seal.

This seal is not simple. It is quietly suspended in the center of a magic circle formed by ancient runes. Those runes are flashing with faint blue light, as if telling a mysterious story from ancient times.

The material of the seal itself looks like neither gold nor jade, and its surface is engraved with extremely complex patterns. Each pattern is like a stream containing mysterious power, flowing and converging on the surface of the seal.

Ye Chen knew very well that this was definitely a treasure, and he flew towards the place where the seal was without hesitation.

The air around him made a sharp whistling sound under the impact of his high-speed flight, as if warning him of the unknown challenges he was about to face.

Ye Chen did not delay. When he approached the seal, he could clearly feel an ancient and powerful aura coming towards him. The aura was like that of a sleeping beast. The slight majesty it exuded was enough to make people feel terrified.
