What did he see?

A magnificent teleportation formation was formed in the deepest part of the cave. A blue formation of light was suspended, surrounded by densely packed ghosts.

Most of these ghosts exist in the Nirvana stage, but two of them are different.

These two ghosts were taller and more powerful than other ghosts. Yang Chen was not sure at first, but after taking a closer look with his spiritual pupils, he was basically sure that these two ghosts had reached the level of A powerful ghost master in the Mahayana period.

"Is there a Ghost Lord?" Yang Chen took a deep breath.

What he is most worried about is the strong man with the Ghost Lord level.

If there is a strong man of this level, then it is already beyond his strength, making some things not so easy to deal with.

Now, Yang Chen did not dare to act rashly and stared straight ahead, unblinking and concentrating.

In this cave, there are not only ghosts, but also humans.

But just like outside the cave, these humans are now bound by restrictions.

What makes Yang Chen curious is what is the purpose of these ghosts to restrain and imprison humans.

He was suspicious outside, and now he was even more confused in his heart.

At this moment, a group of humans were lined up in a line, standing in front of the teleportation formation.

I just watched a few ghost generals in the Nirvana stage grab a human and throw them into the formation.

This person entered the formation, and a ghost hand appeared out of nowhere, with fierce claws tearing out, suddenly tearing this human into pieces.

The screams lingered, and the human being was covered in blood and flesh, completely swallowed by the formation, and turned into the energy of the formation.

"Using human bodies to sacrifice formations? Is this necessary?" Yang Chen said to himself.

You know, things like the sacrifice formation are extremely vicious, but it doesn't necessarily have to use a human body. The ferocious beasts are more cost-effective. The underworld takes such risks and uses human bodies just to sacrifice the formation in front of it?

Apparently not.

Soon, something happened that stunned Yang Chen.

In this formation, a strong man of ghost general level suddenly appeared.

This powerful man of the ghost general level was teleported here like this. Yang Chen couldn't figure out the reason.

"what happened?"

Yang Chen was speechless.

He continued to look at it.

It was discovered that these ghosts only need to throw a person into the teleportation formation, and then a ghost general will teleport from a distance.

Moreover, after Yang Chen carefully observed it, he discovered that the ghost general that was teleported seemed to be related to the strength of the human being thrown in.

The stronger the Nirvana-stage human sacrificed, the stronger the Nirvana-stage ghost generals summoned.

"What's going on?" Yang Chen was puzzled.

"This is the accompanying summoning formation. The underworld uses this formation to conquer cities and territories, and it takes over many interfaces. If this interface does not pay attention to this formation, it will be defeated by the underworld sooner or later."

At this time, a voice suddenly sounded in Yang Chen's mind.

This frightened Yang Chen so much that he calmed down after hearing the sound.

He was so frightened that he broke out in a cold sweat. It turned out to be the Binghuo Tianfeng.

Binghuo Tianfeng's voice was as arrogant as ever, but it opened some eyes to Yang Chen and gave him some basic understanding.

"You mean, companion summoning formation? What kind of formation is this?" Yang Chen asked inexplicably.

"This is a unique creative formation in the underworld. As long as a few ghost generals reach the enemy's rear, they will create this formation and then capture living beings, such as you humans. They only need to capture a human and invest In the formation, a ghost can be summoned from a distance. The strength of this ghost is determined by this human being. Basically, a human with five thousand Taoist inscriptions can summon a ghost with ten thousand Taoist inscriptions. General." Binghuo Tianfeng said.

Yang Chen suddenly realized that this was the principle.

No wonder.

A large group of ghost generals appeared inexplicably, and it turned out that they all relied on this mysterious formation.

The appearance of a ghost general of the Jiuyin Ghost General level relies on a strong man with tens of thousands of Taoist inscriptions. No wonder the Jiuyin Ghost General keeps saying that Jiang Zhiliang is a good sacrifice and is reluctant to kill him.

Jiang Zhiliang's 14,000 Taoist inscriptions can basically be exchanged for a ghost general with 28,000 Taoist inscriptions?

Yang Chen didn't know if there were such ghost generals in the extremely Yin land, but the underworld was so big, it was hard to tell.

King-level ghost generals have appeared. Who dares to say that the legendary emperor-level ghost generals do not exist?

"The ghost generals were infinitely summoned from the extremely dark place and slowly penetrated. But fortunately, there were not many strong men from the Mahayana period near the Wushuang Camp. Otherwise, the strong men from the Mahayana period would fall, and then the ghosts from the Mahayana period would be sent out. It’s a big deal to summon him to the rear. I’m afraid the entire camp will be in trouble and the entire southern region will be destroyed.”

Thinking of this, Yang Chen also sighed with emotion.

In this way, the birth of the Extreme Yin Land may also be the reason for this companion summoning formation.

Otherwise, how could the southern border be suddenly divided into an extremely gloomy place.

"Hey, that's right. How do you know so much about the underworld?" Yang Chen asked curiously.

"Humph, who do you think I am? During my lifetime, I fought in the south and north, and fought countless supernatural ghost generals in the underworld. I understand their methods. It's just a companion summoning formation. See you here. There are more." Binghuo Tianfeng said slowly.

Yang Chen doesn't know the origin of this Ice and Fire Heavenly Phoenix, but this arrogant guy has transcended Wu Jing and must know a lot. He has to make use of this, and maybe it can help him in many things.

Just like this companion summoning formation, he already has a lot of clues.

"This human's Dao inscriptions are pretty good. With eight thousand Dao, we can bring over a ghost general with sixteen thousand Dao inscriptions." The Nirvana stage ghost general looked at the imprisoned human Nirvana stage powerhouse and threw him away on the spot. Entered the summoning formation.

"Fortunately, not many Nirvana stage powerhouses on the human side have been arrested. Those who were really arrested were all in the second batch. And I released all the second batch. Otherwise, I really don't know what level of ghosts were summoned. Will come out." Yang Chen muttered to himself.

Thinking in his heart, Yang Chen also started to think about it.

With so many human beings, will he refuse to save them, or will he make other choices?

Yang Chen didn't have a clue, he was more inclined to ignore it.

It's not that he's cruel, but it's just that even if he gets involved now, it won't help. Can he rescue all these people?

But just as he was thinking this, Yang Chen was suddenly startled.

Binghuo Tianfeng yawned and said Youyou: "I said Yang Chen, do you really not care? Didn't you see that there is a boundless level strongman tied up at the very corner?"

Yang Chen was originally very calm, but suddenly his pupils suddenly shrank.
