This giant beast, Lin Chen didn't know how to describe it at all, except for the long fangs in his mouth, Lin Chen couldn't see any other features.

"It's good I didn't go in..."

Lin Chen muttered a little scared, but Lin Chen also understood at this time, that is, the mirror above was simply a trick, everything was reflected by the mirror below Lin Chen, confusing the illusion of others, only when you looked at the mirror below, you could see the real scene above.

"In that case, then I guess you're the real third gate, right?"

Lin Chen took a deep breath, took a small step back, and then stepped on the mirror below, and when the mirror shattered, Lin Chen also hurried back to safety.

The mirror shattered little by little, and just when Lin Chen thought it was going to be completely shattered, the cave began to shake violently.

Lin Chen was no stranger to this kind of vibration, because after Lin Chen came to the first gate last time, a similar vibration had occurred.

The shaking lasted for nearly a minute or so, and then the mirrors in the cavern shattered.

After these mirrors were shattered, the surrounding area of the cave turned back into stone walls again, and Lin Chen couldn't even find the fragments of the mirrors here, and the whole scene was exactly the same as the scene in the first stone gate that Lin Chen entered.

"Is the mirror an illusion, or did I not even come to the second door?"

Lin Chen threw this question in his heart, but no one could give him an answer.

Lin Chen struggled for a while, until the mural that appeared on the third stone gate gave Lin Chen the answer, the mural of this stone gate was completely different from the murals of the first gate and the second gate.

Lin Chen stepped forward and looked carefully, it was still composed of twelve fragments, in the painting was a huge laboratory, this laboratory was like a manor of thousands of square meters, because it was very large, so the painting must have been drawn from a long distance, and Lin Chen naturally couldn't find any details in the laboratory.

"The first door seems to be a huge factory behind the middle-aged man, could it be that this cave is related to some kind of experiment?"

Now the mystery of the cave is more and more of a headache for Lin Chen, unknown things are coming one after another, Lin Chen deeply feels that his IQ is completely insufficient, so there is no other way for Lin Chen to continue to explore the next door.

"Bang!"

The old rule, first hit your divine power on the stone gate.

Since Lin Chen's realm had changed drastically since the last time he came here, it was no longer a problem in terms of divine power.

When the twelve fragments filled the mural, the stone gate opened again, and Lin Chen continued to explore the secret behind the third stone gate.

......

After Lin Chen walked into the third door, everything in front of him completely changed, it was no longer a cold stone wall, nor a strange mirror, but a wooden house, with a rocking chair in the corner of the house, and a small swing next to the rocking chair.

Except for the rocking chair and swing that Lin Chen saw, there was nothing else.

"Huh?"

Lin Chen suddenly found that there was a book on the rocking chair, and with a curious gaze, Lin Chen slowly walked to the rocking chair.

"The mysterious universe?"

Lin Chen looked at the five words "Mysterious Universe" written on the title of the book, and he was particularly puzzled in his heart, the laboratory in this cave, the universe, it was simply confusing.

Lin Chen picked up the book and looked at it casually, it was recorded the most mysterious and incredible deeds in the universe, Lin Chen didn't know anything about the universe, and a lot of professional terms were used in it, looking at Lin Chen for a headache.

"It's like a science fiction movie..."

Lin Chen was really a little speechless, for science, the universe or something, Lin Chen was completely in a state of ignorance.

"You won't let me decrypt it again, will you?"

After Lin Chen put down the book, he glanced at the wooden house, and did not find any stone doors, or other places similar to exits, seeing that he couldn't find the exit, Lin Chen simply sat on the rocking chair and continued to look at the "Mysterious Universe" that gave him a headache.

Looking at it this time, Lin Chen was also much more serious than the first time, after all, it was likely that the secret of this room was hidden in the book.

Lin Chen found that in this book, there is a lot of pen and ink spent on time and space, in Lin Chen's world, almost scientific knowledge only exists in the research of some scholars in the secular world, and they, the cultivators, have never disdained science, after all, the ability possessed by the cultivators is the existence of those scientists in the secular world, who cannot understand it at all, and cannot analyze it.

"How many kinds of time are there in the universe? As long as certain conditions are met, can you travel time? ”

Lin Chen looked at these questions and was also explained in the book, which said that in fact, no one can travel through time, but in the vast universe, time is divided into many pieces, for example, when we see the light emitted by the stars, it actually existed a long, long time ago.

Regarding this, Lin Chen can still understand, after all, this is also a kind of common sense, but the book mentions that as long as your speed is fast enough, you can also carry out another kind of time and space travel, for example, you can teleport before the light in the universe arrives on the earth, which is also another sense of time and space travel.

"Ten thousand years at a glance?"

Lin Chen suddenly thought of this idiom, and then Lin Chen imagined such a possibility, if the distance was far enough, something that Lin Chen did in a certain environment might be passed on to future generations through a medium many years later, just like what happened in front of their eyes.

It's like a mirage, it seems to be close at hand, but it is far away.

"I see, if the stars in the night sky represent the present in our eyes, then on the other side of the stars, we belong to the past, but in fact, the stars belong to us to the future?"

Lin Chen guessed in his heart that he now had a little more understanding of the time introduced in this book.

"Could it be that since I entered this third gate, I have traveled to some point in time?"

Lin Chen was startled when he thought of this, if this was the case, then where was Lin Chen at this time?

At this moment, Lin Chen's mind was completely uncontrollable to think about these unknown mysteries in the universe, and his consciousness began to gradually get lost in this small wooden room, and the whole person seemed to have entered a meditative state, without even blinking his eyes again.

"Lin Chen, hurry up and come to your senses!"

Suddenly, the middle-aged man in Lin Chen's body suddenly issued a warning voice to remind Lin Chen, and when Lin Chen reacted, he found that he was sweating on his back, and the sweat soaked Lin Chen's clothes.

......
