Lin Chen was no stranger to this kind of bright glow powder, it was a substance that was easy to obtain, of course, it was only available to cultivators. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

The structure of the bright firefly is similar to a chemical called insect luciferase, a chemical called insect luciferase, which reacts with oxygen through the stomata of the firefly to emit a faint fluorescence at night.

And the god cultivator happened to absorb the insect luciferase of the firefly, making it a very low-end lighting method, which is almost not used by the god cultivator in the modern world, so for a while, Lin Chen did not react.

Lin Chen looked at this half of the candle a little distracted, how many firefly chemicals had to be absorbed to make this effect, theoretically speaking, as long as there was air, this candle would not go out.

Lin Chen really couldn't figure it out, even if this Divine Cultivation Realm didn't have so many modern equipment from the secular world, it wouldn't take such low-end means to illuminate.

And the first floor is brightly lit, so there's no reason to use fireflies to create light.

Lin Chen ignored the half of the candle and walked around the room, wanting to see if there were any other clues, when Lin Chen walked towards the window, suddenly!

"That's not right!"

This room is airtight, where does the oxygen come from?

Lin Chen suddenly realized that when he came in just now, the window and door were closed, and when he looked at the window at this moment, he found that this window was made of special materials, and the ventilation effect was extremely poor, and this bit of oxygen could definitely not maintain the light of the firefly candle.

Lin Chen, who felt more and more incredible, finally began to get serious.

"It seems that this room is hiding some secret that no one knows!"

Thinking of this, Lin Chen once again swept the entire room with his divine sense, but this room was so big, except for some tables, chairs and benches, there was nothing special... Wait, this painting?

Just when Lin Chen was distressed, he suddenly saw a painting in front of the table, to be honest, it was normal for this kind of room to have paintings, but the painting in front of him was just a picture scroll spread out, and there was nothing except for a person's signature and seal in the lower left corner.

"What the hell is this?"

Lin Chen frowned, thinking hard, this painting is really weird, no one paints blank, and he shamelessly signed his name underneath.

"Gu Yue!?"

Lin Chen took a closer look and found that the signature was a person named Gu Yue, and the name Gu Yue, Lin Chen always felt that he had heard it somewhere...

Putting aside the name Gu Yue, Lin Chen tried hard to think about the various possible outcomes, but overturned them one by one, and finally, Lin Chen set his eyes on the half of the candle again.

Lin Chen circled around the candle in various ways, looking at the blank painting in front of him from different angles with the help of the candle's light source, but the result disappointed him again and again.

"I still don't believe it, in such a small room, what tricks can you Lu Yuzong play!"

Lin Chen inexplicably felt that his IQ had been insulted, and his heart became more and more impetuous.

On the candles and paintings, Lin Chen spent nearly half an hour, but there was still no solution, at this time, Lin Chen leaned against the other wall opposite the painting with some frustration.

"What!?"

As soon as Lin Chen leaned in, he felt something chrome him, and he turned around to look, but found that there was no foreign object on the wall.

"What's weird, what's going on?"

Lin Chen was very puzzled, why such a smooth wall would make Lin Chen feel that there was a foreign object behind him, in order to test that what he just felt was not an illusion, Lin Chen stretched out his hand to the wall.

"Sure enough!"

As soon as Lin Chen's hand touched the wall, his eyes widened, because he could clearly feel that there was a foreign object on the wall, and it seemed to be invisible.

"Color-changer?"

Lin Chen opened his mouth and said, this kind of color-changing body is very similar to the chameleon in the animal kingdom, they can integrate the color on their bodies according to the different environments, so as to protect themselves.

"Lu Yuzong, you are the founding emperor? Am I mistaken, you should be a biologist?"

Lin Chen complained a little speechlessly, all the strange things in this room seemed to be next to animals.

After putting aside these distractions, Lin Chen began to study what this 'invisible' color-changing body was.

"Oh... I see, firefly candles can't illuminate you, right?"

Lin Chen looked at the blank wall in front of him and said, I don't know who I thought he was talking to.

"Are you comfortable with this kind of light?"

Lin Chen smiled slightly, directly took out the mobile phone, and adjusted it to the flashlight mode, and sure enough, under the light of Lin Chen's flashlight, the color-changing body began to show its original form little by little.

"That's good!"

Lin Chen seemed to have solved a big problem, and his heart became happy.

When this color-changing body began to gradually take shape, Lin Chen's eyes widened.

"It's... Could it be that you!?"

Lin Chen thought of a terrifying possibility, and ten seconds later, the color-changing body also confirmed Lin Chen's thoughts.

I saw that on the wall, a human face slowly appeared, to be exact, it was a male face with closed eyes, if it was more precise, this human face had half a head, so it would form a convex state, so that Lin Chen could find it.

"Scareless?"

If it weren't for Lin Chen, who would have been surprised by it, if he were an ordinary person, he would have to scream and run away in fright if he didn't faint at this time.

When this face appeared, Lin Chen began to set his eyes on the candle.

"Oh, I see, the blank painting is just an illusion, but you and the face are actually the organs of this room, right?"

Lin Chen looked at the candle with a victorious smile and said.

Then he jerked around to look at the face, and the result was ... Nothing happened, the room was still the same room, and the candle was still the same candle.

The only difference is that Lin Chen's expression is now more bitter and hard.

At this time, the atmosphere of the room fell into an inexplicable embarrassment, and Lin Chen looked at the candle and then at the face behind him a little speechlessly.

"I'm really... Wait!"

Lin Chen was just about to turn on the spit mode, but at this moment, he was stunned in place, staring at the blank mural in front of him motionlessly.

The blank painting at this moment is no longer blank, and the face behind Lin Chen has appeared on it, of course, it is just an outline.

"Could it be that the painting is a human face?"

Lin Chen guessed in his heart, there is no better explanation at the moment, no matter how complex and incredible the design of the mechanism in this room is, the clues must be hidden in the candles, the human face, and the paintings.

Lin Chen sometimes looked at the candles, sometimes at the faces and paintings, and after a while, Lin Chen's eyes suddenly lit up.

"I see!"
