Golden Forbidden Land: I am at the highest level, exploring the secrets of immortality

Finally, I found the four keys in my hand, but I don't know what they are used for. I have been racking my brains to find clues these days, and I am even about to collapse, but there is still no clue. Maybe I should find the answer in another way.

I sat in the library and looked outside.

I don't know why, the weather has been bad these days, and the whole city looks gloomy, as if it will collapse at any time. So much so that I look at the people walking hurriedly in this city, and they look a little nervous.

"Sir!"

Suddenly, when I didn't even know what I was thinking, a voice appeared in my ears.

"Sir!" I don't know how many times he shouted before I came to my senses, looking a little lost.

"Oh!" I came to my senses and saw that it was a young man in his early twenties, and then he looked at me with a confused face, maybe not knowing what happened to me.

"Is there anything wrong?" I asked.

You know, I am now in almost the best library in the city. This is just a private library. Ordinary people can never enter, let alone disturb guests easily, so I feel a little strange. Is there something strange about this person?

"There is someone outside looking for you."

He told me, and then stared at me seriously, as if waiting for my answer.

"Who?"

I stared outside, but I could see clearly outside the huge glass window, and there was not even a ghost. How could there be someone?

"Where is he?"

I asked.

"Sir, you don't need to look, the man has left." The man answered. Obviously, he should be a staff member of this library, so he looks very polite and will not make people feel disgusted.

"However, before the man left, he gave me something and told me to give it to you."

The man said seriously.

"Things?"

I was puzzled.

The man seemed to be ready to take out the things, but he seemed a little embarrassed, and didn't even know what to do. He just didn't move for a long time, and seemed to want to say something, hesitating, and didn't say it out.

"What could that be?"

I was still wondering in my heart at that time, because I didn't know who the other person was, why would he leave something for no reason, and even leave without leaving his name. Of course, I could never say that it was Da Kui or other friends, because they would never leave without saying a word.

So, it is very likely that I don't know this person.

"This..."

The man hesitated.

"What?"

I had a bad look.

I could see it from his face, and even saw the fine beads of sweat on the man's forehead, and he wiped it hard.

"It's this..."

Soon, the man took out a piece of stone that looked like black soil from his pocket, which puzzled me.

"What is this?"

I asked.

The man suddenly said, "No, it seemed to be something like gold just now, but I don't know why it turned into this color..."

Speaking of this, the man seemed a little uneasy, even a little anxious, as if he was anxious to explain something.

"What?"

I almost shouted.

The man became even more anxious, and then explained what happened just now. It was said that there was a man with a mustache, about forty years old, who looked very mysterious. He stared at the library for a long time, as if he was looking for someone, but he did not come in. He just left a square object and asked the man to give it to me.

"Does he know me?"

I asked with a frown.

"I don't know."

The man answered immediately.

I looked at the black brick-like object in my hand, puzzled. But this thing seemed very light in my hand, like a piece of paper. I could never imagine that a palm-sized stone slab was as light as paper.

"What do you think this is?"

I asked.

The man did not answer, and looked stunned.

"How could it change color?"

The man was still mumbling in his mouth, with a look of suspicion.

"Maybe..."

The man seemed to be still guessing something, staring at the stone slab with his eyes, as if something terrifying would appear on the stone slab in the next moment.

"Ah?"

Suddenly, when everything was quiet, for some reason, the library had a power outage and it was pitch black all around. It was already 6 or 7 o'clock in the evening, and I was going to stay for a while before going back, but the power went out.

Damn!

There were about a hundred people in the library.

They were all a little surprised and stunned, and even couldn't see anything around them.

"What's going on?"

Those people seemed panicked, and I suddenly heard a very strange sound in the library. Yes, it sounded like a heartbeat, but at this moment, it sounded like breathing, almost covering up all the noise, and the sound was getting louder and louder.
