The source of the Corrosion River is a curved wall, like a huge city wall.

A huge circular city wall wraps a huge city.

The city wall is so high that the aurora can't be escaped during the day.

Under the city wall is a circular moat, and this moat is a stagnant circular river. When the water in the city slowly seeps out, it forms a source of water for the Corrosion River to flow downward.

There are six entrances to the city wall: A, B, B, D, W, and Ji.

Each entrance is dozens of miles apart.

According to Sun Zhuoyue, the Qingyou Gang generally likes to go to the C-shaped entrance, so that they can easily exchange door blocks with other gangs and check the storage bags of the monks who have entered the formation.

The entrance closest to the River of Corruption is the A-shaped entrance.

The entrance door was in tatters and was obviously blasted away by magic instead of opening naturally.

Big Ice Explosion Technique!

Big Ice Explosion Technique!

Big ice blasts exploded one after another.

The overwhelming ice sword pillars drove Hou Dongsheng and Ghost Emperor to the A-shaped entrance.

Big Ice Explosion Technique!

A huge icy snowball hit the ground.

The four female ghosts + ghost emperor + Hou Dongsheng from spring, summer, autumn and winter broke into the A-shaped entrance hand in hand.

A huge icy snowball exploded at the entrance, and sharp knife pillars were inserted into the stone wall, leaving huge scratches one after another.

Two aqua blue rays of light fell in front of the A-shaped entrance.

The light disappears.

It was Lin Huaibing and Xue Qiansheng.

I saw Lin Huaibing put his hands behind his back and said with slightly narrowed eyes: "Now the Sanxiu Hou Dongsheng has only two ways. One is to fall into the abyss of death by mistake in the maze formation; the other is to return here. I want you to set up an ambush here and kill me with your own hands."

Kill Hou Dongsheng."

Hearing this, Xue Qiansheng showed hesitation.

"Why... don't tell me that you, the mighty Jindan Master, can't ambush and kill a foundation-building monk?" Lin Huaibing asked with slightly narrowed eyes.

Xue Qiansheng: "Why does Fellow Daoist Lin insist that I take action?"

The corners of Lin Huaibing's mouth curled up slightly.

Do you still want me to make a clear decision?

After Lin Huaibing used the Great Ice Burial Technique to destroy the second-level Ironwood Golem, he kept using the Great Ice Explosion Technique to expel Hou Dongsheng from a distance.

He just wanted to leave the opportunity to kill Hou Dongsheng to Xue Qiansheng to get his name.

Of course, a small part of the reason was to prevent Hou Dongsheng from suddenly throwing a human bomb.

After all, truth and falsehood must be guarded against.

Sanxiu Hou Dongsheng should be just a pseudonym, and his true identity must be Wan Ziyi, the elder of the inner sect of the Demon Flame Sect.

Forcing the Jindan master of the Xue family on Bingyu Island to kill an elder of the Demon Flame Sect in front of him.

Naturally, the entire Bingyu Island will turn towards the Lin family.

Lin Huaibing: "Fellow Daoist Xue, don't forget that I owe you a favor not to kill you."

Xue Qiansheng raised his eyes and glanced at Lin Huaibing. Although the two of them were at the same level of cultivation, he really didn't dare to fall out with this woman.

After all, he was defeated.

Xue Qiansheng: "That Wan Ziyi..."

"It's Sanxiu Hou Dongsheng!" Lin Huaibing corrected.

Xue Qiansheng: "Yes... Sanxiu Hou Dongsheng, he just said that his master Liuyin Zhenren is coming..."

"What!? That crazy woman from Liuyin is coming? Why didn't you tell me earlier?"

Xue Qiansheng: "You didn't even give me a chance to say it."

"You!? What a waste!" Lin Huaibing was furious.

Maze array.

There was a passage for three people to walk in parallel. Hou Dongsheng, the Ghost Emperor, and the four female ghosts of Spring, Summer, Autumn and Winter stood in a row hand in hand.

The passage is about three feet high, with an arched dome above the head. The bricks used to build the passage are huge stones about half a person's height. The stones are not very regular, and there are luminous plants growing between them.

There is no sunlight in the cave, so it can only rely on plants to shine.

Looking ahead: The cave is so deep that I don’t know where to go.

Looking back: The cave is so deep that I don’t know where it starts.

The group of them broke into the dark A-shaped entrance and suddenly appeared in the passage of the maze array.

Don't know where it came from, and don't know where it will go.

Everyone let go of their hands.

The four female ghosts in spring, summer, autumn and winter, the Ghost Emperor, and Hou Dongsheng are still in the same place, but once they start walking, not long after, the people gathered together will disappear one by one, and finally only one person will be left walking in the dark maze.

The formation will send the lone intruder to any one of the "Magic Eye Island, Shui Shui Lake, Xuanyang Cave, A-shaped Entrance, Banshee's Lair, and Uncertain Whirlpool."

The Ghost Emperor used his magic skills to collect all the four female ghosts of spring, summer, autumn and winter into the storage bag.

Hou Dongsheng and Ghost Emperor were the only two people left in the empty passage.

The Ghost Emperor took out two middle-grade Yin stones from his storage bag, holding the Yin stones in both hands to absorb the Yin spiritual energy inside.

Ghost Emperor: There is no Yin spiritual energy in it, and there is probably no Five Elements spiritual energy in it.

Hou Dongsheng: Normally, this is a prison, not a place for cultivation.

While the Ghost Emperor was absorbing the spiritual energy, Hou Dongsheng took out the "Top Ten Basic Formations" from his storage bag and turned to the article "Liuhe Basic Formations".

Ever since I learned that the real name of the labyrinth array is: Inverted Liuhe Array.

Hou Dongsheng began to study the basic formation of Liuhe.

Unfortunately, the Liuhe Formation is too obscure and time is short, so I couldn't find any relevant information.

There is only one book called "Top Ten Basic Formations" that contains a brief description of the Liuhe Basic Formation.

Liuhe is the four directions above and below.

The basic formation of Liuhe is the combination of the twelve earthly branches.

Zi is combined with Chou, Yin is combined with Hai, Mao is combined with Xu, Chen is combined with You, Si is combined with Shen, and Wu is combined with Wei.

The characteristic of Liuhe's basic formation is that it is comprehensive and weatherproof.

The six-pole ice shield and the six-pole magic cage all refer to the Liuhe basic formation.

The ice magic cultivator was holding the six-pole ice shield without any cover at all, and the demon trapped in the six-pole magic cage was also unable to move.

The ancient monks used the characteristics of the Liuhe Formation to trap the Three-Eyed Demon King and imprison him to this day.

I do not know how long it has been……

The second soul's mana was finally fully restored.

Hou Dongsheng's research on the basic formations of Liuhe has also come to an end.

Each basic formation is vast and can evolve endlessly.

One Five Elements Formation is enough for countless formations to practice the Haoshouqiongjing.

The Liuhe Formation and the Five Elements Formation generally have infinite mysteries. With Hou Dongsheng's current level of formation, it may be possible to crack a first-order Liuhe Formation, but it is absolutely impossible to break a fourth-order inverted Liuhe Formation.

However, being unable to break the formation does not mean that there is no way, otherwise Hou Dongsheng would not dare to break in directly.

Netherworld Taoism: The migration of heavenly ghosts.

I saw the Ghost Emperor puppet patting the storage bag and taking out the doll.

Just throw it away.

The rag doll fell to the ground and transformed into a charming woman.

This woman is dressed in green, with green hair all over her head, and her feet are barbed iron feet, which is the spring green color of a mid-level ghost general.

Ghost Emperor: "Go ahead and go wherever you want."

Chunlu, who had the intelligence of only five or six years old, didn't care about the formation or not. He stepped forward with his iron feet on the bluestone floor.

A moment later.

Chunlu disappeared from the sight of Hou Dongsheng and the Ghost Emperor, and could not even be noticed by their spiritual consciousness.

Ghost Emperor: "Tai Ming merges with spirits, and heaven and ghost move."
