The sky was shining, and the colorful vitality spread layer by layer like a tide, and a crystal jade hand covering no less than ten kilometers flew out from the center of the glow, slowly grasping towards the Ten Thousand Ghost Mountain.

Countless black pillars of air, hideous ghost claws, and skeleton demons rose from the Ten Thousand Ghost Mountains and crashed into the crystal jade hand, and were crushed into pieces by the slowly sinking jade hand and re-pressed down.

The big hand slowly but firmly pressed down, pressing straight on the Ten Thousand Ghost Mountain, and there was an earth-shattering loud noise.

"Boom!"

The pitch-black Ten Thousand Ghost Mountain exploded under the suppression of indescribable power, countless black qi wrapped in broken stone scattered and scattered, and countless Yin Spirits scattered along these fragments to escape, but a layer of gray light suddenly appeared in the void several miles away from the Ten Thousand Ghost Mountain, blocking all Yin Spirits like an enchantment.

Emerging along with the gray light was the Taiji diagram that covered the sky.

The power of the Ten Thousand Ghost Mountain is not comparable to any ghost town, Ye Chen cleaned it up effortlessly, and the Ten Thousand Ghost Mountain is not the value confiscated by the ghost town, it was directly refined into powder by him, and when he left, there was a huge pit with a diameter of more than ten kilometers and a depth of more than ten kilometers, and a large stream of yin qi erupted from the ground, occupying the giant pit, forming a place similar to a lake.

Destroying the Ten Thousand Ghost Mountain, Ye Chen did not continue to chase it, but disappeared directly, and did not appear for a long time, which made the lord of another ghost city hundreds of kilometers away from the Ten Thousand Ghost Mountain breathe a sigh of relief.

He wiped out several ghost cities in a row, or completely exterminated, which had already made the ghost emperors of the ghost world in Pishan panic, and there were already more than a dozen ghost emperors sending envoys to each other, and there was a tendency to unite, he suddenly disappeared, and this alliance stopped.

Ye Chen did not leave the Bishan Ghost Realm, but found a random place to hide, with his current strength, it would be difficult to find his traces unless a powerhouse of the same level passed by him.

He hid for no other reason, just to improve his strength.

Destroying the Six Ghost Cities and Ten Thousand Ghost Mountains in a row will definitely arouse the vigilance of other ghost emperors and unite, and he is not a fool of course he would think of this, plus Sima Yan injured him with some kind of treasure before, which made him also a little vigilant, realizing that it was too reluctant to destroy the entire Bishan Ghost Realm with his current strength, and it was better to improve his strength.

But this time, instead of directly using potential points to increase mana, but...

He opened the attribute ability panel, and his gaze fell on the Nine Heavens Xuan Sutra, now that he had advanced to the seventh layer, it would take a full twelve million potential points to advance to the next level.

After a slight hesitation, he smashed his mind hammer on the Dao Fa, and in an instant, a huge amount of potential points burned, and almost instantly, a layer of invisible and transparent flames burned on the surface of his body, and the yin soil around the retreat cave slowly changed under the illumination of the transparent flames, turning into a layer of crystal like a jewel-like texture.

Fortunately, it is the Dao Fa that is improved, and if it is the body that is improved, I don't know how long it will take for more than 10 million potential points to be consumed.

It only took about a minute for the Nine Heavens Xuan Sutra to be raised from the seventh layer to the eighth layer, and these twelve million potential points were exhausted, and in this minute, countless contents about this top-level Dao method appeared in his mind, from the basic Dao method to the derivative ability, all kinds of experiences, as if he had practiced for hundreds of thousands of years, and his body quickly adapted to this change.

The Nine Heavens Xuanjing was promoted to the eighth layer, and his strength increased very obviously, but there was no qualitative change, and the biggest changes in the Nine Heavens Xuanjing were in the third, fifth, seventh, and ninth layers, corresponding to the Sword Immortal, Scattered Immortal, Earth Immortal, and Heavenly Immortal.

When the Nine Heavens Xuanjing is raised to the ninth layer, he can use this to trigger the Heavenly Tribulation to come, and if he succeeds in crossing the Tribulation, he can transform a golden pill in his body into a real Yuan Shen, in the words of the Xuanmen Qi refining system, called Heavenly Immortal, or True Immortal.

Ascending from the 7th to 8th requires 12 million potential points, and ascending from the 8th to 9th requires a full 20 million potential points.

Ye Chen did not hesitate to consume twenty million potential points and once again improve the Nine Heavens Xuan Sutra.

Different from the previous layer, the ninth layer of the Nine Heavens Xuanjing is the last layer of this top-level Dao method, and it is also the most critical layer, which is related to the key elements of the monk's transcendence from the mundane and towards the realm of immortals, which is extremely important.

At the same time, the ninth layer of the Nine Heavens Xuanjing also contains the key to how the monks can induce the Heavenly Tribulation, refine the divine soul, and finally shatter the pill and gather the gods.

These low-level Dao methods are not recorded, only top-level Dao methods such as the Nine Heavens Xuanjing are recorded, and the entire Shushan World can allow monks to practice to the top Dao methods of the Heavenly Immortal Realm, adding up to no more than twenty.

The time consumed by the last layer of the Nine Heavens Xuan Sutra was more than ten times longer than that of the previous layer, and the key was these important factors.

When the invisible flame on his body slowly merged into his body, Ye Chen opened his eyes, and two thunderbolts suddenly shot out of his eyes, punching two bottomless holes in the crystallized rock wall in front of him.

With a light exhalation, a gust of wind blew in the small cavern, forming a small whirlpool centered around him.

This place is too small, if it is outside, with his current strength and realm, he can stir up the wind and clouds within a radius of dozens of miles in one breath.

At this point, although his mana has not increased a little, his current strength is several times stronger than before.

If one point of mana can exert one point of power when the seventh layer of the Nine Heavens Xuanjing is at the ninth layer, now at the ninth layer of the Nine Heavens Xuanjing, he can exert at least two or three points of power with one point of mana, this is the gap between the realm.

Moreover, the Nine Heavens Xuan Sutra had been raised to the ninth level of consummation, and he had comprehended several top-level demon refining supernatural powers recorded above, including two powerful immortal supernatural powers.

However, the Immortal Family's supernatural power needs him to survive the Heavenly Tribulation and be promoted to the Heavenly Immortal before he can use it, and now, he needs to trigger the Heavenly Tribulation.

With a thought in his mind, Ye Chen looked up, even if there was a thick layer of yin soil blocking it, he could sense the heavenly tribulation aura coming from the high heavenly dome above the earth several kilometers thick.

That is, he, dare to trigger the catastrophe so casually, other monks to cross the catastrophe, which is not prepared early, as little as ten years or more than decades, some of the accumulation is not enough may have to be prepared hundreds of years in advance, that is, to accumulate external strength, but also to prepare all kinds of catastrophe treasures, even the location of the catastrophe is thousands of choices, like him dares to cross the catastrophe in the place where thousands of ghosts gather for fear is unheard of in the history of Shushan.

Ye Chen's accumulation of external strength is still insufficient, although he has destroyed six ghost cities in a row, it is still insufficient.

The time for him to cultivate the Tao is really too short, from the beginning of the cultivation to now, I am afraid that he has already begun to cross the Heavenly Tribulation in less than ten years, and he has not accumulated much external strength before, and now although he has accumulated a large amount of external strength in the Pishan Ghost Realm, it is still a little short of the external strength needed to cross the Heavenly Tribulation.
