"arrive."

Accompanied by two A-level personnel, Xia Ren once again came to the entrance of the 18th floor.

One of them said: "The doctor has entitled you permission, and now you can enter and exit freely. We will wait for you outside until you are sent back to the hospital."

It seems that the last assassination made the doctor pay a lot of attention to his safety.

However, Xia Ren then thought that if this is the case, then his whereabouts have been under the surveillance of the other party in the past two days.

"Luckily I didn't really attack those containment items."

Xia Ren calmed down and came to the elevator door on the 18th floor.

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

[Permission authentication is enabled.]

【Special permission authentication: Class A】

[Permission authentication is passed, welcome.]

Unlike the cumbersome procedures that Dr. Liao passed the last time, Xia Ren directly opened the elevator door on the 18th 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 was twisted, and he was teleported to the space where the doctor was.

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

"However, this is good, and your presence is minimized, which is also conducive to our next actions."

"The next action?"

Xia Ren said in confusion.

"As you requested two years ago, I will take you to...Serraino Grand Library!"

Xia Ren felt a violent palpitations, and his tentacles stretched out from behind his head, instantly wrapping him tightly.

As soon as he finished speaking, the ancient silver key on the doctor's chest suddenly burst out with dazzling light, illuminating the entire room like daytime.

Xia Ren took back the control of the tentacles, separated a gap, and leaked out his vision, but found that the outside was covered by a white light.

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

It was an old man wearing a white long gown, thin and a little hunched.

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

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

"Can't it..."

A bold guess appeared in his mind.

The old man ignored him, but took off the silver key from his neck and reached out to slowly cut down the air in front of him.

A strange thing happened. The silver key was like a sharp blade, which seemed to have cut open space. Where it passed, a pure black channel gradually appeared.

"Come here."

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

Xia Ren hesitated for a moment, took back his tentacles, and entered the passage.

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

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

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

"I'm a PhD."

The old man explained: "The full name is Laban Seulisbery."

The doctorate he mentioned naturally cannot refer to a degree.

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

"Are you the same person as the one who soaks in a jar as a specimen?"

"That was to suppress my own strength, and, to keep me awake."

The doctor took a step forward: "I always traveled through various time and space, including the past and future, where every space is real, which often leads to my inability to tell whether I have truly returned to the original world or started another journey when I ended a certain time and space trip.

Losing in the long river of the world is extremely dangerous, so I sealed some of my strength, preventing myself from traveling twice in a short period of time 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 has been changing.”

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

“What does it mean?”

"end."

The doctor continued to move forward, and Xia Ren had to keep up.

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

"Wouldn't that be..."

Xia Ren could not imagine what kind of pressure and despair the doctor had been suffering.

"But I said that the future has been changing, and perhaps the ending is not the only ending. If you give up, there is really no hope."

"Besides, I have seen the light." The doctor's tone was filled with a hint of longing.

"Light?"

“Yes, light.”

The doctor stopped.

"At that time, I was still young and far from mastering the power to spy on the future, so I could only travel through the past and collect the knowledge of taboos. But I had been in that time and space for too long, which led to my return. I fell into the gap between time and space and fell into a sunny world where the sky was extremely clear, with birds flocking, the ground full of vitality, and the eyes were full of green. Various lush plants grew among collapsed buildings. Countless healthy people built new cities by the ruins, living under the sky without the threat of old gods and pollution."

The doctor sighed softly: "I lived there for a while, but later because of the long time travel, the real world has already repelled me, causing me to lose most of my memories. I can only vaguely remember that there, I spent the most pleasant time in my life."

Xia Ren inexplicably remembered the desolate world connecting humans and dreams.

Collapsed buildings, strange and bizarre plants, eternal clouds in the sky, and the occasional terrifying shadows in the clouds.

Perhaps, that is the end of the world.

"Are we going to that library?"

"Yes, the Great Library of Serraino, you'd better remember this name."

The doctor continued to walk forward and said, "The longer I stayed in other spaces, the more serious the rejection of reality will be. The sequelae of long-term time and space travel is that I have lost time in the real world little by little, and have degenerated from my original old age to my youth. What you see now is my real age."

"What if it continues to degrade?"

"In reality, I will be completely erased, I will lose my spatial coordinates, and be lost in all time and space forever."

"Will you die?"

"Won't."

"When thinking about it from another perspective, will it be immortal soon? I feel that this is more like a gift."

"Gift?"

The doctor laughed in a low voice.

"No, this is a punishment. You won't understand."

"Okay." Xia Ren shrugged.

A doctor who can travel through time and space is difficult for Xia Ren to understand this state itself.

"By the way, I forgot to answer your question just now."

"We are now on our journey to the library, and every step under you and me seems short, but it actually spans several light years," the doctor said.

"ha?"

Xia Ren was a little confused about what he suddenly said.

"Forgot to tell you that the Grand Library of Seraigno is not on Blue Star."
