When the fat men heard this, they quickly looked up at the ancient building model in Chen Hao's hand. They were amazed at the vivid appearance.

"Damn! I just said that the things in this mirror are strange, and it turns out that the weirdness is on the top of this cave." said the fat man.

"It turned out to be a model. I understand. This ancient building model is hidden on the top of the cave and reflects the light source through a special material in the cave. This is something we can't see, so we mistakenly think that the ancient building came out of the mirror." Wu Xie suddenly realized.

"Come on, since the mystery here has been broken, hurry up and the foreman has agreed to pay." The fat man urged.

Chen Hao nodded and stuffed the ancient building model in his hand back to avoid triggering any mechanism, and then quickly climbed down from the wall.

After seeing him come down, the fat man said with great interest: "There is so much tincture in this cave. Moreover, looking at the direction of the tincture, it is obviously intentional. I think it must be spectacular when burned. Why don't we try it?"

On the walls around the cave, the rock cracks are all covered with tiny oil, circling upwards in circles. If ignited, it is very likely that a spectacular sea of ​​fire will form.

It is precisely because of this that the fat man is curious and wants to cause destruction. He is too tired along the way, so he wants to take the opportunity to take revenge.

After hearing the fat man's words, Chen Hao walked into one of the gaps and looked at it. He found that there was a cotton core mixed in the turmeric oil, which was obviously a fire lead.

He nodded, expressing his agreement with the fat man to do this.

Wu Xie was worried that the ignition point of these tincture oils would burn the entire cave, and he disagreed with the fat man's approach.

The fat man said with a serious expression: "The innocent and innocent comrade, the minority obeys the majority, and even Brother Hao supports me to do this. You should stop his mother-in-law and mother. If you don't let this fire go, I will feel uncomfortable."

Wu Xie frowned and said, "But... look at the tincture oil here. Once it is lit, it must be burned out all the tincture oil hidden in the entire cave before it will be extinguished. If you use such a large fire to put out the fire, how many people will die? Moreover, the oil grooves of these tincture oils are connected. If you can't just extinguish one side, the other side will burn immediately. Don't bother the comrades from the army to come and put out the fire?"

The fat man touched his chin and looked at the entire cave, nodding, "It makes sense, but these tinea oils must be related to the secret of this mirror. Innocence, don't you want to know what secrets are hidden in this mirror?"

After hearing his words, Wu Xie showed a hesitant expression, not knowing how to answer the fat man's words for a moment.

Seeing that he was hesitant, the fat man said, "Okay, naive, don't hesitate, do whatever you want. Teacher Ma said that practice is the only criterion for testing the truth!"

After saying that, the fat man took out the windproof lighter from his pocket without waiting for Wuxie to agree and ignite it with a snap.

"Damn fat guy, don't do anything randomly! These tinea oils..."

Before Wu Xie could finish his words, the fat man had thrown the windproof lighter into one of the oil grooves.

The ignition point of this tinder is extremely high. Almost the moment the lighter is thrown out, flames burst out from inside, and then a fire dragon burst out from the oil ditch.

The fire was too fierce, and Chen Hao was worried that the two of them would be burned by the fire, so he quickly pulled the shocked fat man and Wu Xie into the mirror of the pool.

Everyone was dumbfounded when they saw the fire dragon gushing out, circling along the surrounding walls. Wherever they went, a mark of fire would be left, illuminating the entire cave.

At the same time, the temperature in the cave rose rapidly, and the air was filled with the smell of tinder oil.

After waiting for more than ten minutes, the fire dragon reached the top of the cave. All the fires formed an inverted trumpet, and the shape looked very spectacular.

All the firelight shone on the ancient building in the mirror, illuminating the ancient building inside, and it looked a bit like a dream.

"Damn, this design is amazing!" The fat man said with a dull look on his face.

Wu Xie cursed angrily: "You are crazy. If there were explosives buried in this cave, we would probably have been buried alive by the stones above our heads! Fatty, can you rely on some tricks and let our brothers live for a few more years?"

Wu Xie looked at the bright firelight in the cave and the clear shadow of the ancient building in the mirror, and immediately understood the principle of the formation of the ancient building in the mirror.

Wuxie explained: "So that's the case. This is actually just a trick, and it comes from a magic trick in Persia."

The fat man asked, "Oh, Persian magic? Then tell me what's so outstanding about this magic."

Wu Xie turned on the flashlight and shone on a dark green stone embedded on the wall, saying: "This stone is called Moon Stone, a special stone in Persia. This stone is very dim in the sun, but it is particularly bright in the moonlight, so it is called Moon Stone."

"The light emitted by our flashlight and the light emitted by torches are all a kind of moonlight, which can greatly increase the intensity of light reflected by the moon stones. The Zhang family inlaid these moon stones in the cave with exquisite techniques, which is very hidden. If they didn't look closely, they would mistakenly think they were just ordinary stones."

"I don't understand what you said. I just want to know how the guy and the others appeared in the mirror of the ancient building?" asked the fat man.

Wu Xie explained: "There is something else in the ancient building model above. The method of style thunder is indeed powerful. Such technology originated from the West. As a result, style thunder used Western technology so exquisitely, which I didn't expect."

"Then what is the purpose of their arrangement of such mechanisms? It's so complicated, it's not meant to scare people, right?" the fat man asked again.

"I guess the purpose of their doing this should be for lighting. Think about it, this ancient building is built deep in the mountain, and there is no light source here. It would be very inconvenient to carry out such a huge project in such a dark environment, so it was built such a lighting system. In this way, it can effectively prevent the torches from being brought into the ancient building. The entire ancient building is made of wood, and it cannot be extinguished once it is burned!" Wu Xie continued to explain.

Wu Xie said with a finger, "I don't know how large the project volume of this ancient building is, but I estimated that even more than 300 people would take three or four years to complete it."

Chen Hao had no time to listen to Wu Xie's explanation. He quickly said, "Okay, stop studying these things. The oxygen here is about to be consumed. We should leave here early."

Both of them nodded after hearing his words.
Chapter completed!
