Xia Ren's grief did not come from the corpse lying on the desk, but the environment in this study.

It's familiar, but it's unfamiliar.

He knew the body wasn't Ebon, but he forgot who Ebonn was.

"Is it a memory that has been tampered with by the system?"

Just like why Lily was so familiar with the building, he couldn't find a proper proof of why.

The feeling of being wrapped in fog and not being able to see clearly made him a little restless.

Xia Ren quickly stabilized his mood, he walked to the desk and slowly picked up the corpse.

The corpse's hair was black, its face was also typical of Dongzhou people, and the corpse was wearing the work clothes of a laboratory researcher, and Xia Ren saw his badge, which read "Professor Yue Yongjie".

The corpse's skin was a little yellow and dull, his lips were chapped, he should have died of lack of water or starvation, but there was still some temperature left on the surface of his body, and when he opened his eyes, the lens was still clear, and there was no zombie, Xia Ren speculated that the time of his death should be within a few hours.

"But how is this possible?"

Xia Ren couldn't figure it out, didn't Yue Yongjie disappear with his students two years ago?

And along the way, he didn't find any food or fresh water near the sea, and there was no trace of life in the building, if he had just died, then what did he survive in the past two years?

Xia Ren's gaze moved to the desk, where the corpse was lying just now, there was a worn-out book.

"Is this the ......?"

His heart beat a little faster, and Xia Ren slowly reached out and took the book in his hand.

The book itself is quite old, and no matter how carefully preserved, it cannot avoid damage.

Its cover is wrapped in oily paper, and it feels a little slippery to the touch, as if it is stained with other people's sweat.

There was no text on the cover, it was just a blank slate, Xia Ren calmed his heartbeat, and only after getting ready did he cautiously turn the first page.

Because when he was looking for the ghoul cub Zhang Xiang before, he had the experience of reading a pagan magic book that caused his sanity to decline and be polluted, so he couldn't be too careful.

The pages had yellowed, and the material had become quite fragile, and Xia Ren saw the strange text symbols on the first page.

He didn't know it, but he tried to understand it.

There was a sudden swelling pain in his brain, and the faint sound of worms wriggling in his ears appeared, and he knew that it was an illusion, that his sanity was already declining, and perhaps the pollution level was rising.

But atypical phobia had to find a solution, and the solution is documented in this book.

He had to read, he had to understand what was inside!

Even if it comes at the cost of being polluted.

In a trance, the field of vision in front of me was becoming narrower, the swelling pain in the skull was getting worse and worse, and the eyes unconsciously wanted to take away from those symbols, unwilling to look any further.

Xia Ren clenched his teeth, sweat oozing from his forehead, forcing himself to keep an eye on the symbols.

Suddenly, in his mind, it was as if a silk thread had broken, and endless knowledge poured into his mind, and the chaotic voice quickly echoed in his ears, like a nightmare, and his consciousness was lost in it......

"Kid, how many times is it?"

"I have two apples, give you a ......"

“b、p、m、f…… Reading as 'human'......"

"Goose goose goose, the song is ......"

"White Spoon's ...... ...... of the land"

"Xiaohong and Xiaoming go to the bookstore ......"

"Last year, in this door today, the face of the person ......"

"The chrysanthemums of the North Sea are blooming......"

It was as if it was another person's memory, forcibly merging with him, and countless scattered images flashed in front of his eyes at a very fast speed like a slideshow.

This knowledge was unheard of, very different from the cultural education he had received since he was a child, and it was a completely new and large and complex system, which was constantly washing away his intellect like a flood.

Xia Ren stood in place, holding the open book in both hands, his eyes glazed.

Lily looked up at him for a moment, feeling a little bored, and then took a step and muttered to herself:

"One, two, three, wooden man!"

She stopped abruptly, then turned her head to look at Natsuhito, and found that he was still motionless.

Lily grinned to herself, and then the smile on her face slowly faded and became a little lost.

"Alas......"

She sat on the floor, holding her fleshy little face in both hands, not knowing why she was unhappy.

There was silence in the study for a long time.

"Underground Diggers."

Xia Ren suddenly spoke, and in a strange pronunciation, he said the words recorded on the page, which was also the name of the book.

After vaguely absorbing the knowledge that appeared in his mind, he found that he understood that these symbols were also a kind of writing.

However, knowledge does not come in a vacuum.

Xia Ren had a faint guess in his heart, this might be ...... It's something he already knows.

But what he just accepted, in the human history of Blue Star, there is no resemblance at all, that set of language and writing system is amazingly mature, the creatures who use this kind of writing, perhaps live in a society that is more developed than Blue Star's existing level of science and technology.

"Could it be that this was once a human civilization?"

Xia Ren couldn't help but remember what he had learned about biology and history.

Human history has a total of 4,000 years of recorded history, thousands of years, archaeologists have gone one after another, trying to trace the history of 4,000 years ago, but have no gains, human beings seem to have appeared in the blue star overnight, human history researchers have explored this huge planet with a total area of 1.9 billion square kilometers, but whether it is 4,000 years ago human fossils, or traces of human activities, there is no discovery.

Some scholars have speculated that humans were genetically mutated by some ape to adapt to the environment based on genetic similarity, but this reason has not been accepted by the academic community.

As a result, the question of the origin of mankind has not been conclusively conclusive.

If the knowledge you have just fused is also from human civilization, then this may be a civilization that has been extinct.

But in this case, a new question arises, who wrote these special written books?

Left and right couldn't figure it out, Xia Ren could only keep this idea in his heart for the time being, waiting for time to study it again.

The immediate priority is to see what knowledge is recorded in this book.

Turning the next page, Xia Ren found that it was written as a poem.

"The Grave of the Sea"

Their minarets are deeper than our deepest tombs

They are illuminated by the light seen by the human eye

Only wingless worms can travel to and from the tomb

The tomb is under the light of the sky and the waves."

Xia Ren remembered that the sentences whispered by Patient No. 3 happened to be gentle with the poem.

He's got it right, it's this book!

Xia Ren suppressed the excitement in his heart and continued to look at it.

A terrifying population gradually became clear in his consciousness.
