Shen Yi had thought about this before. Why did human civilization exist in most of the countless multi-dimensional universes? From the perspective of the mysterious root, there is only one explanation.

In the mysterious root of every multi-dimensional universe, there exists a rule that he named "human origin".

This is the obvious reality.

But the question is, how can such rules exist in every multidimensional universe? Shen Yi previously suspected that there is a greater "root" that transcends the multidimensional universe.

It's like the relationship between the origin of the universe and the origin of the dimension and plane.

But now, he saw another possibility from Gui Den.

Pollution, assimilation, modules.

Yes, if the demons can use this modular root to pollute the rest of the universe, then "human origins" can do the same.

Even further, if we think about it, the root of the ghost den is also related to human beings.

All things have souls, and souls can give birth to ghosts. However, most of these ghost disasters that lead to the end of the world only target humans. This is especially true in Mo Yan's world without demons. At least from the report submitted by Mo Yan, the various terrorist incidents that have occurred in that world so far have only targeted humans and are almost harmless to animals.

This is enough to explain a lot.

"Captain, are you planning to go into the haunted den to check?" Ding Xiang couldn't help but ask.

At present, if we want to obtain more information and break the impasse, it seems that the only way is to go to the ghost cave.

But Shen Yi shook his head.

"No, wait a little longer," he said.

He had a hunch that in the den of ghosts, there might be some extremely terrifying things related to the origin of the system.

With his current strength, intuition is no longer just intuition, it must be taken seriously.

"Both my strength and the Pan-Human Guardian Association's strength are still lacking accumulation, so I'll seal them up first. At least, wait until my strength can't be improved any more and the association has digested all the technologies in the Level 8 mall before taking risks," Shen Yi said.

"Yes." Ding Xiang nodded.

She gritted her teeth secretly, thinking that such a mistake must never happen again.

After that, everything seemed to be back to normal.

Shen Yi also paid attention to the follow-up of Mo Yan's mission.

The salvation plan he adopted was similar to the one Shen Yi had used in the Tang Dynasty world. Both of them were about exploring a cultivation method suitable for that world, and then passing it on to the human civilization of that world, and then cultivating a small number of powerful elites so that they would have the power to fight against ghosts.

And there was no further change in the ghost den.

Everything meets the level 5 doomsday difficulty standard.

This also seems to verify another guess Shen Yi made earlier.

Even if there is some existence behind the modular roots of the ghost den, that existence has not paid in-depth attention to every universe that has been invaded by the ghost den and implanted with modular roots. Otherwise, the other party should be able to easily determine the existence of Shen Yi from the roots created by Shen Yi.

And Shen Yi even continued to save the doomsday of level eight difficulty after a certain period of time.

With his current strength, plus the foundation that the Pan-Human Guardian Association obtained from the eighth-level system mall, even if he encounters a doomsday event like the Black Sea Evil God again, he can easily resolve it.

So I didn’t feel too much difficulty.

Instead, he wholeheartedly enjoys the satisfaction that comes from saving the world and protecting humanity.

And constantly looking for clues.

With this purpose in mind, he actually discovered quite a few traces.

"It's not just 'human origins'. Many roots in the multi-dimensional universe are modular, and the higher the magic universe, the more obvious it is."

Shen Yi is currently in an eighth-level doomsday universe.

There are also countless multi-dimensional planes in this universe.

It is worth mentioning that this is a vast universe for cultivating immortals.

Yes, in the root of the universe here, there is no magic, no alchemist, and no witchcraft. There is only one path of practice, and that is to cultivate immortality.

There are countless immortal cultivators in the countless multi-dimensional planes, and there are also a few eighth-level beings called "Immortal Emperors", who jointly created the "Immortal Realm" and led the seventh-level "True Immortals" in countless multi-dimensional planes into the Immortal Realm.

If it were before, Shen Yi wouldn’t have thought much about it even if he saw such a world.

But now.

However, he saw very familiar rules from the origin of this universe.

——The rules of cultivating immortals.

Moreover, compared to the roots seen in other worlds before, the rules of cultivation in this world are more perfect.

Even many of the immortal cultivation traditions in the system seem to come from this world.

This is not the main reason why Shen Yi attaches importance to this world. The most important thing is that there is a legend about the "origin of the immortal road" here.

That was during a period countless epochs ago when even the Immortal Emperors had fallen countless times. In the entire world, there was no such thing as cultivating immortals. There were only mortals who sank and floated in the red dust like ants. Then at a certain time, a road to immortality suddenly appeared, and from then on, mortals had the possibility of becoming immortals.

Does it sound familiar? They regard "cultivating immortals" as "ghosts appearing" and "the road to immortality" as a den of ghosts.

That would explain it.

This is just like the origin of the ghost den in the world without demons. The origin of this world was also created by a certain "immortal realm", so it is so similar to the "laws of cultivating immortals" in the rest of the universe.

"There is one more piece of evidence for the 'pollution theory'." Shen Yi flew slowly in the fairyland and sighed softly, "Can the possibility of the 'big universe theory' be ruled out?"

"Captain, there is no way to verify that legend." Ding Xiang still followed Shen Yi, and seemed to have a headache. "Even the most ancient immortal emperor is completely unaware of it."

They just came out from the "Most Ancient Immortal Emperor" of this world.

It was an ultra-ancient being that was said to have lived for hundreds of millions of years.

It is even so ancient that many people in this world have never heard of it.

Shen Yi went to the emperor's tomb specifically where the man had been sleeping for who knows how many epochs and dug this man out.

"I just can't figure it out." Shen Yi was still thinking, "Assuming there really is a 'Fairyland' that spreads the roots of 'Cultivation of Immortality', why doesn't it remain continuously connected like the ghost den? Is it because as time goes by, the fusion of different dimensional universes will also separate?"

Obviously, no one can give him an answer to this question.

The idea of ​​this last volume is a bit confusing. TT has a headache. I have thought of the ending setting but not the ending plot.
