At first they didn't believe it, but then he watched the Immortal King's disciple's attack from afar, and it was really like a knife with a cold golden light. Even though the level was not much different from their Majesty, ten Majesties could not withstand a single blow from that person.

This is the difference between inheritance and heritage.

Just a disciple who was randomly sent out can have such strength, needless to say how terrifying that immortal king is.

What's more, the Immortal King made several moves, and the sky was filled with thunder. Although one did not dare to watch it, just hearing about it was terrifying enough.

Therefore, Luo Yi and others have always been cautious.

They only dared to select some newly born evil ghosts that had never absorbed blood and energy and brought them here to accumulate strength, hoping that the immortal king would return one day.

Shen Yi looked at his expression and could guess roughly what he meant.

Possessing this kind of self-control, although he is no longer human, he is not a demon either.

In this case, the crisis of destroying humanity might not fall on them?

After Luo Yi answered, he seemed to have no patience to explain further and simply found an excuse to leave.

And Shen Yi was just walking casually on the "street".

Although it is a street, in fact, it is the Yin energy that restricts these ghosts from floating around freely. I previously thought that the metaphor of the earth being equivalent to the air was not accurate enough. It should be equivalent to the sea. After all, these ghosts can move freely up and down.

Moreover, Shen Yi noticed.

The ghosts here are not very powerful, but their intelligence is generally stronger than the evil ghosts in the human world, and they can carry out basic conversations.

It may be related to the fact that they rely directly on Yin Qi rather than the Qi and blood of living beings to take shape.

Shen Yi walked around like this.

Although he only brought down a weak consciousness, his observation ability was not weak, so he could clearly feel that the space in some places was obviously distorted, and the Yin energy was constantly spreading from these distorted places.

So that's it Shen Yi has completely understood.

The reason why the world ends.

"I never thought that this would be the end of the world." Shen Yi sighed while being in the sky fortress.

"Captain, have you figured it out?" Ding Xiang also realized something from Shen Yi's words.

"Yes." Shen Yi nodded and explained, "Yin Qi, this special spiritual energy, is not Nirvana, but comes from other worlds."

"Other worlds?" Dingxiang was surprised.

"There is a possibility of mutual interference between parallel worlds, but this possibility is extremely rare." Shen Yi said this and then shook his head.

The end of the world itself is extremely rare, but no matter how small the probability is, as long as the possibility exists, it will definitely happen in the countless universes representing infinity.

In this case, it is only natural that fate would be broken to this extent.

The huge interference from another world has completely torn apart the established destiny of this world.

"Captain, can you determine the strength of the other world?" Ding Xiang's first reaction was the degree of danger.

The other world represents the unknown.

Although Shen Yi’s strength is not weak now, there are still many unknowns in this invasion from other worlds. Even if the purpose is to save the world, his own safety must be given the highest priority.

"Just from the characteristics of Yin Qi, it won't be very high." Shen Yi said calmly, "There is an essential gap between the sixth and seventh levels. This kind of spiritual energy does not have the possibility of giving birth to a seventh-level extraordinary individual. From this point of view, we don't have to worry about our safety. It's just that the end of this world will have more evolutionary possibilities to face."

Shen Yi was not sure to what extent the two worlds would blend.

Now it is just the emergence of psychic energy.

But if this fusion goes a step further and even completely opens the passage to another world, then it will be troublesome.

"Then should we continue observing?" Ding Xiang asked again.

"That's right." Shen Yi said, "That Li Jiancheng just wants to stay alive and develop, and has no plans to invade the ground for the time being. In this case, there is no need to rush to do anything. I want to observe the development trend of this 'underworld' and the evolution trend of interference from other worlds first."

If Shen Yi wanted to, he could destroy Li Jiancheng, a mere fourth-level man, in an instant.

Even a depth of 18,000 meters could not save him.

However, saving the world is not just about resolving a temporary threat and calling it a day.

We must ensure that human civilization can continue to develop after they leave.

Ding Xiang nodded and said nothing more.

After this day, Shen Yi had one more thing to do, which was to observe this underground area.

The speed of the spread of Yin Qi and the speed of interference from the other world, and best of all, it would be possible to discover the situation in the other world.

Li Jiancheng and other ghosts had no idea that they had been exposed.

They still carefully expanded their staff and hid themselves.

Don't say anything harmful.

They didn't even dare to show their faces above ground.

They have realized that no ghost who dares to show up will be able to escape.

Of course, not every ghost has such self-control ability.

Li Jiancheng's younger brother, Li Yuanji, is a typical example. He had a very strong character when he was alive and was fearless. This was even more true after his death. He repeatedly wanted to go to the ground to eat humans to become stronger, but was forcibly suppressed by Li Jiancheng.

But it also attracted a group of evil spirits with equally brutal personalities.

But in Shen Yi's opinion.

It is more likely that he will be killed by Li Jiancheng before he takes any action.

Li Jiancheng's patience with him has reached its limit. After transforming into a ghost, his personality will be greatly affected. Although reason can suppress the cruelty in his heart, as time goes on, this ubiquitous cruelty will inevitably affect his mind.

But, being brutal alone does not lead to madness.

So the original question still exists, that is, since evil spirits have intelligence, they should know that keeping humans in captivity is the way to maximize their interests. In that case, the humans in this world will be miserable, but humanity will not be extinct. However, the fact is that humanity in this world is eventually extinct.

There must be some other crisis.

This is why Shen Yi did not alert the enemy.

He continued to do his own thing, staring at the changes in this ghost den, and at the same time, perfecting the ghost-controlling system.

After realizing the source of the Yin energy, he gained a lot of inspiration.

Another three months passed.

Finally, a relatively complete ghost-controlling system was created by him.

Shen Yi even called back the four people he had sent out, including Gu Yan, to the fortress.

They are the ones who have the most contact with the Ghost Riders.

However, this training system is not so wonderful for ghost riders.
