Gao Cheng saw this powerful ghost, but he didn't remind Nie Xiaoqian. The other party has experienced more than a dozen battles in the underworld, and has experienced a lot of sneak attacks with this kind of hidden aura of powerful ghosts, so he has long been prepared for it.

I saw that this powerful ghost slowly moved to Nie Xiaoqian's side, screamed violently, and hissed with powerful claws, slashing towards Nie Xiaoqian's condensed body.

"Extreme Yin Frozen Demon Dao!"

Nie Xiaoqian, who was originally condensing the whirlwind to sweep away the Yin Soul, looked cold, suddenly turned her head, condensed the Law Seal with both hands, and the pure Yin Qi in her body exploded violently, combining with the Yin Qi of the Netherworld to form a cold and freezing power. Whew! A pale blue breeze blew. Wherever the pale blue breeze passed, there was a clattering sound of freezing.

The ghost who made the sneak attack showed a panicked look, like a solidified amber, turned into an ice sculpture by the freezing air, and in addition to it, hundreds of nearby Yin Spirits were also affected and turned into ice sculptures.

After turning all the unjust ghosts who came to attack him into ice sculptures, Nie Xiaoqian urged her mana and waved her sleeves to shatter all the ice sculptures.

Call!

When all the unjust ghosts turned into pure yin qi and were absorbed by her temporarily cultivating into beads, she breathed a long sigh of relief. But before Nie Xiaoqian could recover her mana, there was another roar, and hundreds of powerful ghosts were surging towards her.

"Nie Xiaoqian's strength is enough to resist a powerful ghost with five hundred years of mana, don't worry for the time being! Go find the traces of the old demon of the Black Mountain first, and find a way to lure him here!" Gao Cheng thought in his heart.

The pure yin qi formed by the body of the nine yin is the best tonic for the powerful ghosts of the underworld to purify the mana and increase the strength, even the old demon of the black mountain will definitely not give up easily after seeing the pure yin qi.

When the time comes, let Nie Xiaoqian forcibly urge the Wuyue True Monument to return to the world, and the old demon of Montenegro will definitely chase after him when he sees the Yin and Yang Channel, and his self-sustaining strength is strong. Then the old demon fell into the trap.

Gao Cheng's plan is very simple, there is no too complicated conspiracy, that is, to use pure yin qi as a bait to lure the old demon to send it to the door himself.

The strength of the old demon of Montenegro has reached the fourth order, and it can be called a fourth-order ghost immortal. This kind of strength is enough to be the king and hegemon in the underworld, but in the environment of the underworld, no powerful ghosts and ghost kings are willing to stay here for the rest of their lives.

All those ghosts are thinking about returning to the world. The old demon's strength is too strong, he can't return to the world with all his strength, if he wants to leave the underworld, he can only break through the realm, enter the fifth order to reach the limit of what the world can hold, and then fly through the sky.

The pure yin qi can help the powerful ghosts improve their strength, and it can also greatly increase the chances of the old demon of the Black Mountain entering the fifth order. Gao Cheng's plan is simple, but he is not afraid that the other party will not take the bait when he uses it.

The underworld is vast and boundless, as if it is in another dimension, but Gao Cheng wandered in the air for a moment and realized that the underworld should be the other side of this world.

Heaven and earth are divided into yin and yang, east and west have positive and negative sides, and the world also has positive and negative divisions of yin and yang. The positive side of the world is the world. Nourish all living beings and constantly improve the origin of the world.

And the opposite is the underworld. Most of the filth and impurities produced in the human world will enter the underworld to form various ghosts and ghosts.

In the previous world, those myths and legends divided the world into three worlds: heaven, earth and man. ”

"The heavenly realm represents the pure spiritual qi, the earthly realm represents the turbid qi, and the human world is a fusion of the turbid qi. The Tao Sutra has clouds, the Tao gives birth to one, one life to two, two to three, three to all things, three to six and six infinity, and those who have extremely high wisdom have studied, the triangle or the three elements are the most stable form!"

Gao Cheng kept guessing in his heart, maybe the closer the form of the world was to the three talents of heaven, earth and man, the more powerful and complete the world became. The central immortal realm in the middle of the star map should be the most perfect world in the entire chaotic space.

Rushing!

Gao Cheng's consciousness flew in the sky of the underworld, and suddenly heard the sound of rushing water, and quickly shifted his gaze to see a wide river flowing slowly on the land of the underworld.

The river is dim, and there are a large number of ghosts floating in it, these ghosts roar and roar, desperately trying to get out of the river, but they have never been able to do so.

Some of the yin spirits with weak mana struggled in the river for a while, and then quietly melted and became part of the river.

"Yellow Spring Water!"

Gao Cheng's heart was shocked, this is the river of the underworld that is famous in all the worlds. The world is immortal, and the yellow spring water continues to flow. The water of the Yellow Spring can make Meng Po soup that forgets the past, and it is also one of the three sacred waters that can dissolve all things in the world.

If there was a drop of yellow spring water stuck to his body, Gao Cheng was not sure that he would get out safely. He cautiously skimmed over the Yellow Springs River and soon entered a vast plain.

The outer side of the Yellow Spring is the periphery of the underworld, and only by crossing the Yellow Spring is the core area of the underworld. Gao Cheng had just flown a short distance when he saw a ghost general in heavy armor roaring past with hundreds of ghost pawns, rushing towards a city far away from the plain.

"The ghost city of the underworld! Such a strong and tyrannical evil spirit, there must be a fourth-order ghost immortal in the city!" Gao Cheng's spirit was shocked, and he quietly came to the bottom, found a powerful ghost, and used his divine thoughts to search for information from its consciousness.

It turned out that this ghost city was one of the ten cities in the underworld, and the owner of the city was the old demon of Montenegro that Gao Cheng was looking for. The body of the old demon is a mountain in the underworld, and I don't know how many years ago the blood of the gods fell from heaven and sprinkled on the mountain, which gave birth to spiritual wisdom.

After years of cultivation, the old demon of Montenegro has a monstrous mana, occupying one of the ten ghost towns, and is known as the top ten ghost kings of the underworld along with the other nine ghost kings. Possessed one-tenth of the realm of the underworld.

"There are also nine ghost kings...... It's a bit troublesome, you can't alarm all the ghost kings, you need to find a way to lure the old demon out!"

Gao Cheng's thoughts turned quickly, and suddenly his mind moved, and a stream of pure yin qi came to his hand through the air, and then fell from the sky, and with a bang, his fingers blasted the heavily armored ghost general into slag, and then deliberately left this trace of pure yin qi on the ghost general's body......

Room.

In the Twelve Yuanchen Great Array. Gao Cheng secretly withdrew his mana, just now he ingested the breath in Nie Xiaoqian's body, and then used the Wuyue True Monument to teleport to the underworld.

"The strength of the ghost general just now is not weak, it should be the henchman of the old demon of Montenegro, it was killed by my distraction, the old demon of Montenegro will definitely be alarmed, and when the time comes, if you find the pure yin qi, you will find Nie Xiaoqian!"

Yan Chixia and Zuo Zihao saw his movements, and couldn't help but glance at each other, and then Yan Chixia asked: "Master, how is Xiao Qian now? If it's dangerous, it's better to let her come back first, with the Wuyue True Monument in hand, there will be a chance to enter the underworld in the future!"
