Although they are all in human form, there is no doubt that these people are real evil spirits.

"Who are you?"

The scholar stared at the evil ghost on the stage, his voice was hoarse but full of obvious fear.

"I am the king of ghosts!" As the evil ghost on the stage finished speaking, the entire palace around him turned into endless black fog in an instant. The terrible deterrent force continued to surge, almost breaking the souls of several new evil ghosts.

The ghost on the stage has reached the fourth level! Under the huge level pressure.

All the evil spirits in the audience knelt on the ground and shouted in fear according to their memories: "Greetings, Your Majesty! Greetings, Your Majesty!"

After a long time, that terrifying aura slowly faded away.

"This place is a ghost den, and it has infinite Yin energy for you to practice." The evil ghost who called himself the king of ghost den said slowly, "But without my order, no one can leave here, go."

"Yes! Yes!" Many evil spirits in the audience scattered.

Afterwards, a ghost with a young appearance and a burly figure came to Your Majesty and knelt on the ground.

"Brother." The ghost's voice was hoarse, and it was as if he had endless resentment when he spoke, "You can only bring back twelve ghosts a day. At this speed, when can you return to the world of the living and take back the world?"

"If you want to be killed, just go ahead." The evil ghost on the stage sneered, "I am the ruler of the ghost world, but the disciple under the Immortal Lord is not much different from me. As long as the Immortal Lord is alive, we are nothing but ghosts and monsters."

"If the Immortal King doesn't leave, do we have to endure it for a day?" The evil ghost kneeling on the ground suddenly stood up and roared, "If you don't dare, then don't call yourself the emperor."

"presumptuous!"

The evil ghost on the stage raised his hand, and the black mist turned into sharp claws, which directly grabbed the evil ghost below the stage and forcibly pinned down half of his body.

It caused screams.

But the evil spirits around were not moved, and even black mist surged, and they were extremely excited.

"If it happens again, I will drive you out of this den of evil." The evil ghost on the stage finally calmed down.

Then he integrated the dug-out body into himself, and black mist and blood rolled one after another.

A handsome pale face appeared vaguely, but it was full of madness.

Shen Yi naturally didn't know what happened underground.

In fact, he was still thinking about what to do.

The best way is actually to explore deep underground. Although he can't go down by himself, witchcraft is an omnipotent power system after all. If he really wants to explore, there are plenty of ways.

For example, using the same invisible lightning element.

But I'm afraid it's hard to find.

The entire earth is so huge, and with the number of layers, the space available for activities is far larger than the surface.

And we are also worried about alerting the enemy. If the enemy hides, it will be difficult to deal with.

If I can't find it, I can't just stay in this world forever.

Having said that, although Shen Yi had anticipated that ghosts might regain some wisdom over time, he did not expect that a ghost could develop wisdom right under his nose without being discovered.

The only possibility is that the ghost possessed intelligence as soon as it appeared, at least before it started killing people.

Or, this ghost is special.

Or, there are other reasons.

If it is the latter, then Shen Yi has a hunch that this reason may be related to the birth of ghosts.

"This kind of change is a good thing. At least we finally have a breakthrough." Shen Yi moved his limbs a little and showed some energy. "I will continue to watch and see if there is any chance to catch the opponent's trace."

Dingxiang didn't say anything, just nodded slightly.

She could only continue to do what she could do.

And Shen Yi was still keeping a close eye on the newly born ghosts in these cities.

Since the other party appears, he will not appear only once.

On the second and third days, seven or eight ghosts were born every day in the cities that Shen Yi was watching. However, most of them would not attract any reaction from underground as long as they started to scare living beings and suck their blood. This was enough to show the vigilance of the underground ghosts, which gave Shen Yi a lot of surprises.

However, since Shen Yi is watching her all the time, there will be a time when they meet eventually.

This is the ghost of an official.

Originally, officials in this world would all cultivate their Qi and blood to some extent, and their physical strength and average life expectancy were much higher than those of civilians who had no conditions to cultivate.

But this official was different.

A sentence.

He was greedy for beauty and had no self-control, and died in bed.

Perhaps he was unwilling to see his beautiful wife belong to someone else, so the evil ghost he turned into after his death was quite resentful. But before he could do anything, he was tied up by chains that stretched out from the ground.

Same as last time.

But this time, Shen Yi was well prepared and attached a consciousness to the official's ghost.

Wizards are also experts in playing with ghosts.

Although this consciousness is very weak and can only see and feel but not do anything, it is enough for preliminary exploration for the sake of caution.

And as we go deeper.

Shen Yi was also quite surprised.

Too deep.

He originally thought that it was already amazing that these ghosts were hiding thousands of meters underground.

But I didn't expect that it would go down to a depth of tens of thousands meters and was still going deeper.

The most important thing is.

The further down he went, the more clearly Shen Yi could feel the increasing concentration of Yin energy.

Yin energy is the spiritual energy that gives birth to ghosts.

A kind of spiritual power that can transform a person's soul and remaining consciousness into a ghost, but it does not come from Nirvana.

There was some excitement in Shen Yi's eyes.

He had been searching for the source of Yin energy but had no results. But now he had found it. The deeper he went underground, the thicker the Yin energy became. This was a groundbreaking discovery. If he could find the source of Yin energy, it would be equivalent to finding the reason for the birth of evil spirits. If he could solve it, the end of the world could be solved fundamentally.

However, when Shen Yi saw the large area of ​​black fog, even his expression changed a little.

Yin Qi, all Yin Qi! Extremely densely gathered together! The concentration of spiritual energy reached level five, even approaching level six. In other words, under this concentration of Yin Qi, very few level six evil spirits might be born.

Second only to the level of gods and demons!

However, Shen Yi is not too worried about his strength. The concentration only represents the upper limit, which does not mean it can be easily reached. The higher the extraordinary level, the more difficult it is. What's more, there is a qualitative gap between concentration level six and concentration level seven. Shen Yi now has no pressure in dealing with the sixth level.

What really concerned him was where this level of psychic power came from.
