Yunhai Peak is named because its peak is extremely high and is surrounded by a vast sea of ​​clouds, making it look like an isolated island in the sea.

There are a large number of buildings where monks live on the top of the mountain. Many of them have been destroyed in battles, and the rest have been weathered away over the past four thousand years, leaving ruins everywhere.

Witch Jiang looked at the building below and felt an urge to go in and explore.

Although she knew that these abandoned buildings had probably been completely emptied out over the past four thousand years, she still wanted to go in and search. What if she could find something good?

It’s just like a girl seeing a shopping street. Even though she has already made up her mind not to buy anything, she still wants to go in and have a look - what if she comes across something that is good quality and cheap and worth buying?

Of course, although she really wanted to go down and try her luck, Wei Dongliu obviously had no such plan. Jiang Li'an could only shut up and say nothing, thinking that there would always be a chance in the future.

Following the advice of the Blood Sea Ancestor, Wei Dongliu quickly reached the edge of the mountain top and found a tall tower there.

The tower was completely empty, without even the most basic tables, chairs or furniture.

Wei Dongliu came to the top of the tower. The roof here was covered with tiles and looked like a bamboo hat from the outside.

Looking out from the window on the top floor, Wei Dongliu discovered that a cave was slowly appearing somewhere on the rock wall below.

Obviously, an extremely powerful illusion was set up around the Naloyana Cave, so that to the monks from the outside, it looked like an extremely ordinary rock wall without any flaws at all.

But if you look down from the window on the top floor of the tower, you can just see through the illusion and locate the specific coordinates of the cave entrance.

Witch Jiang imitated his actions and looked out of the window, and sure enough, she saw the hole appear.

"It's really interesting." She said in amazement, "Ordinary monks are driven by utilitarianism. If they go up to the top floor and find that there is nothing, they will definitely turn around and leave without looking back. Who would think of looking down from the window here?"

"Let's go." Wei Dongliu jumped out of the window, stepped on the sword light in the air, and rushed directly to the cave entrance in the rock wall.

Jiang Li'an followed closely behind. The two landed at the entrance of the cave, then cast a lighting spell and walked in.

After just four or five steps, the road ahead was blocked by a rock wall.

I saw four large characters engraved on the rock wall:

Taiyi Tongxuan.

These four words seemed familiar. Wei Dongliu thought about it for a moment and soon remembered that Elder Taiyi Tongxuan of the Jiejiao sect had left similar secret words in his suicide note. It was said that it had been passed down among every generation of the Tongxuan sect's leaders.

Taiyi Tongxuan is the first half of the sentence, and the second half is...

"All methods break the Tao." Wei Dongliu said slowly.

Just as he finished speaking, the rock wall suddenly disappeared slowly, revealing a hole as big as a person.

It turns out to be a voice-controlled door!

Wei Dongliu took the lead and walked in calmly. Witch Jiang followed him closely with great interest and secretly wrote down the command that Wei Dongliu had just said.

The two of them walked through a long corridor and entered a simple secret place.

There was a stone hall inside with a statue standing in the center, but there were no exits around it.

Wei Dongliu immersed his spiritual consciousness into the stone statue, and heard a voice around him asking:

"What do you want?"

"Do you have any Taoist method?" Wei Dongliu planned to test it first, "First, let's learn a secret method to refine a demon. It must be a very powerful demon."

Witch Jiang's ears immediately pricked up.

"There is a 'Secret Method of the Six Caves of Gods and Demons in Beiyin'," the voice replied. "The Six Caves of Gods and Demons come from the Dengdu Luo Mountain in Beiyin. They are resistant to swords and spears, water and fire, and are immortal. They can only be restrained by the Seven Treasures Starlight Brilliant Spirit Lamp."

"Okay." Without waiting for Witch Jiang to speak, Wei Dongliu confirmed directly.

I saw the surrounding rock walls suddenly spread out in all directions, revealing a vast world.

The stone statue in front suddenly came to life, rolled on the ground, and turned into an evil Taoist priest, pinching his fingers and chanting:

"Beiyin Dengdu Luoshan, the six caves of ghosts, gods, demons and monsters, obey my command!"

In an instant, a strange wind blew.

Although it seemed like a sudden storm, Witch Jiang's instinct quickly gave her a warning. She shouted "Daoyou, be careful", and then shook out several gods and demons from her sleeves. They were all evil ghosts with eight feet tall, green faces and fangs, and stood in front of the two men.

When the evil wind blew upon the gods and demons, several evil-looking, half-real and half-virtual demon heads immediately emerged and started biting the gods and demons all over their bodies.

Some gods and demons roared wildly and attacked around with their weapons, but they were like knives cutting through water and sticks hitting the wind; all of them passed through the demons' heads without any force.

After a while, these gods and demons were bitten all over their bodies, and black air was coming out of them. Suddenly, they cried out in pain, and then turned into black air again and drilled into the sleeves of Witch Jiang.

Wow! Witch Jiang's eyes lit up, and she realized that these six Beiyin cave gods and demons were really invulnerable!

She used to be a disciple of the Colored Eel Fairy, and the Taoist tradition she learned was the "Secret Methods of Gods and Demons with and without Forms".

Among them, the thirty-six gods and demons were eight-foot strong men, all of whom had the strength to move mountains and cover the world. They were covered with numerous wounds but did not retreat.

The seventy-two formless gods and demons hide their bodies, are silent and can kill people in the ghost den.

But no matter whether they are gods or demons with form or without form, their weakness is that they are not strong enough. For example, once Xu Yinglian's Great Light Flame burns, no matter whether they have a form or not, they will all die; or if An Zhisu's flying sword cuts off their heads, they will definitely die.

Being difficult to be injured by swords and guns is far from being truly "swords and guns-proof"!

Jiang Li'an coveted the secret technique, but she was not stupid enough to ask Wei Dongliu to get it for her. She just bravely stepped forward and shouted:

"Friend Wei, please step back! I will block these demons for you!"

"No need." Wei Dongliu pressed her shoulders with his left hand and pulled her behind him. He drew out the Ten Thousand Demonic Sword with his right hand and stabbed forward.

The Ten Thousand Ghosts Evil Sword pierced into the evil wind, instantly exerting a pulling force on the demon.

However, the six demons from the Northern Yin Caves seemed to have sensed the crisis in advance, and they hid themselves in the evil wind and became invisible.

“Hehehe.” The evil Taoist priest opposite said, “The secret method of our sect’s Beiyin Six Caves Gods and Demons can refine the Heavenly Demons that can shuttle back and forth between Taiyin Cave Heaven and the real world. Any attack methods in the real world will not be effective against the Six Caves Gods and Demons.”

"There is only one magic weapon called the Seven Treasures Starlight Brilliant Spirit Lamp, whose light shines upon all the worlds. Even gods and demons hiding in the six caves of the moon can be locked onto and illuminated by this magic lamp. It is the greatest threat to our sect's lineage..."

He talked continuously, explaining the advantages and disadvantages of "The Secret Technique of the Gods and Demons of the Six Caves of Beiyin", and then began to elaborate on the cultivation methods, mantras, required resources, etc. He did not keep any key details private and explained them completely.

However, while the Taoist was imparting the magic, his hands were very clear. He directed the evil wind to continue circling around the two men, and drove the gods and demons to bite them, as if he was determined to destroy their lives.

Wei Dongliu swung his sword calmly, and whenever a god or demon just appeared beside him, he would force them back with a clean and neat sword strike, without any signs of exhaustion.

Witch Jiang's eyes lit up and she silently memorized the formula in her heart, planning to refine the Six Caves of Beiyin Gods and Demons after returning so as to increase her value in Wei Dongliu's heart!
