He imitated Dr. Liao's previous actions and pasted his identity token on the screen next to him.

[Authentication is enabled. 】

[Special Authority Certification: Level A (Reaper)]

[Authorization passed, welcome. 】

Unlike Dr. Liao's cumbersome procedure last time, Xia Ren directly opened the elevator door on the eighteenth floor.

He looked at his identity token in surprise, and then walked into the elevator.

Arriving at the familiar open space, after a while, the surrounding space distorted, and he was teleported to the space where the doctor was again.

The doctor opened his empty eyes, looked in his direction, and said, "It's strange, I thought you could regain some strength, but you are weaker than I imagined."

"However, this is also good. Minimizing your presence will also benefit our next actions."

"Next action?"

Xia Ren was puzzled.

"According to your request two years ago, I will take you to... the Seraino Great Library!"

Xia Ren felt a violent palpitation, and tentacles stretched out from the back of his head, wrapping him tightly in an instant.

As soon as the words fell, the quaint silver key on the doctor's chest suddenly burst into dazzling light, illuminating the whole room like daylight.

Xia Ren regained control of the tentacles, and opened a gap to reveal his vision, only to find that the outside was shrouded in white light.

Immediately afterwards, in this white space, other colors gradually appeared.

It was an old man in a white gown, thin and somewhat hunchbacked.

The old man turned his head and faced Xia Ren, who saw the same silver key hanging around his neck as the one on the doctor's chest.

Looking up, Xia Ren saw the position of the old man's eyes, wearing a pair of almost opaque black sunglasses.

"Could it be..."

A bold guess emerged in his mind.

The old man ignored him, but took off the silver key around his neck, stretched out his hand and swiped it slowly in the air in front of him.

A strange thing happened. The silver key was like a sharp blade, as if it had cut through the space. Where it passed, a pure black passage gradually appeared.

"come on."

The old man waved to him, then stepped into the passage and disappeared.

Xia Ren hesitated for a moment, retracted the tentacles, and entered the passage.

As soon as he left the white space with his hind feet, the entrance to the passage was immediately closed.

Xia Ren was nervous for a moment, then looked forward.

In the entire dark space, only the silver key on the old man's neck exudes the only light.

"I'm a doctor."

The old man explained: "The full name is Laban Hulus Bailey."

The doctor he said naturally cannot refer to a degree.

As far as Xia Ren knew, there was only one "doctor" in the entire foundation.

"You and the one soaked in the jar as a specimen are the same person?"

"It was to suppress my own power, and, to keep me sane."

The doctor took a step forward: "I always shuttle in various time and space, including the past and the future, where every space is real, which makes me often unable to distinguish whether I am real or not when I end a certain period of time travel. After returning to the original world, another journey was started.

It is extremely dangerous to get lost in the long river of the world, so I sealed part of my power to prevent myself from making two consecutive space trips in a short period of time, so as to ensure that I can always stay awake. "

Xia Ren pondered the information contained in his words, and asked: "So you see the past and the future?"

"The past cannot be changed, but the future is always changing."

The doctor seemed to recall some bad memories, and said: "I can only see some vague futures, such as certain facts that cannot be changed."

"Refers?"

"end."

The doctor continued to take a step forward, Xia Ren had to keep up.

"The familiar world will collapse, and human beings will eventually perish. This is the countless futures I have seen. No matter how I change it, the ending will not change."

"Isn't that..."

Xia Ren couldn't imagine what kind of pressure and despair the doctor had endured all this time.

"But as I said, the future is always changing. Maybe the end is not the only ending. If you give up, there is really no hope."

"Besides, I have seen light before." There was a hint of longing in the doctor's tone.

"Light?"

"Yes, light."

The doctor stopped in his tracks.

"At that time, I was still young, and I was far from mastering the power to spy on the future, so I could only travel back to the past and collect those forbidden knowledge, but I stayed in that time and space for too long, and there was a problem when I returned. In the gap between time and space, I fell into a world full of sunshine, where the sky is extremely clear, birds flock in groups, the ground is full of vitality, green eyes are everywhere, all kinds of lush plants grow among the collapsed buildings, countless healthy The people of the world built new cities around the ruins, living under skies free from the old gods and threats of pollution."

The doctor sighed softly: "I lived there for a period of time, but because of the time travel for too long, the real world has rejected me, and I have lost most of my memory. I can only vaguely remember that in the There, I had the happiest time of my life."

Xia Ren inexplicably thought of the barren world connecting humans and dreams.

Collapsed buildings, weird and bizarre plants, the everlasting dark clouds in the sky, and the occasional terrifying shadows in the dark clouds.

Perhaps, that is the scene of the end.

"Are we going to that library?"

"Yes, Seraino Great Library, you'd better remember this name."

The doctor continued to walk forward, and said: "The longer I stay in other dimensions, the more serious the reality rejects me. The sequelae of long-term time travel is that my time in the real world is gradually lost. , I have degenerated from old age to youth, and the appearance you see of me is my real age."

"What will happen if it continues to degenerate?"
