The walls filled with iron juice are rare in the history of China, and the walls of the Potala Palace, which were built 1,300 years ago, are filled with iron juice from the plum wood.

It is also a tomb more than 1,000 years ago, the tomb of Tang Gaozong and Empress Wu Zetian, the tomb of Tang Qianling, is also made of stone, and the gap is filled with iron juice, which can not only maintain the stability of the tomb, but also has the function of anti-theft, and no one has broken it until today.

Unexpectedly, as early as the Qin Dynasty more than 2,000 years ago, on the other side of this hundred altars, the name is Qianji Pavilion in the Fuxi Realm, which is also made of molten iron on the wall.

I have to say, this is a big deal.

"And this kind of practice?"

Zhuge Yinglong obviously heard for the first time that he could also pour molten iron into the wall, so he couldn't help but increase his posture.

In fact, this method is indeed once and for all, but most of the buildings in ancient times were built of wood, how can the wood withstand the red-hot iron to be poured? That must not be dissolved directly......

So while this method is useful, few people know about it, and that's why.

"Squeak......

This door is an iron door, Li Zimu put his hands on the door and pushed it back hard, only to finally push the door open slowly, Zhuge Yinglong saw this, and hurriedly ran over to take a hand, pushing the iron door on one side to the innermost.

As soon as the door of the "black ......" was pushed open, the spirit opened his eyes curiously and looked inside, there was nothing in the black, and the flashlight was dark and unclear.

"Damn, it's so bright!"

As soon as the words of the spirit fell, hundreds of oil lamps in this room lit up at the same time in an instant, and the sudden appearance of light made the eyes of several people who were already accustomed to the darkness light up and became blind for a short time, Zhuge Yinglong couldn't help but complain.

"Why did it suddenly light up all of a sudden......"

Looking at the brightly lit appearance inside, Zhuge Yinglong said in surprise, he was a little surprised, it was still dark and black, but it became brilliant in the next second.

Within seconds of the door opening, it was all lit up.

"The ghost lights the lamp? This ghost is running too fast, isn't it? Hundreds of lights......"

Zhuge Yinglong thought about it carefully, the four of them were still standing at the door, but the oil lamp suddenly lit up, there must be no one here, so who lit this lamp?

Ghosts?

"Good girl, I've never heard ghosts blow out lights, and I've never heard of ghosts helping to light lights......"

Zhuge Yinglong shook his head and said, he didn't have any fear of ghosts, probably because he had seen it once, so he believed that there were ghosts in this world, and he had a way to cure ghosts, so of course he didn't have to be afraid.

"You're not afraid?"

Li Zimu turned his head and looked at Zhuge Yinglong with interest, the smile on his face was meaningful.

"Cut, what am I afraid of? It's not that I haven't seen ghosts, the fate of those three ghosts last time, boss, didn't you see it, I cleaned it all up in two or three clicks!"

Zhuge Yinglong held his head high and said proudly, just kidding, what kind of big scene has this Taoist master never seen?

"Then have you ever thought that this is a two-thousand-year-old ghost?"

Li Zimu nodded in agreement with his words, and then said softly without hurrying.

"Damn, boss, don't scare me......"

This sentence frightened Zhuge Yinglong and immediately took a step back and jumped out of the threshold. He forgot a stubble just now, he had seen ghosts, but he had only seen the first seven powerful ghosts, two thousand years of ghosts, how could they absorb resentment to the level of the ghost king, and he could breathe to death when he breathed......

"Unproductive"

Chi Ling couldn't help but sneer at Zhuge Yinglong's appearance again, she was not very afraid of the two thousand years of powerful ghosts that Li Zimu said, after all, she had also seen the powerful ghosts and white concubines with Li Zimu before, and it was also two thousand years, and she was not so terrifying.

Well, it did scare her silly at the time, but now, with my previous experience, I'm not so scared, and there's Li Zimu here, isn't it?

"It's just scared like this......"

Li Zimu looked at Zhuge Yinglong's cowering appearance and shook his head and said, he was very sure that these oil lamps were lit by himself, and they had nothing to do with what the hell, just now he just wanted to scare this guy.

Sure enough, when people get old, they like to tease these little kids and see their jokes......

"Ever-bright lanterns? You mean they've been burning for 2,000 years? Wasn't it still dark just now, and I'm not blind. ”

Zhuge Yinglong said suspiciously, he had heard the three words of the everlasting lamp, and he knew what it was.

With mermaid paste as a candle, the one who will not be extinguished will last for a long time.

It is clearly recorded that there is an everlasting lamp in the mausoleum of Qin Shi Huang, and it is said that the everlasting lamp will never be extinguished, even if the tomb is opened again after a thousand years, the everlasting lamp inside still exudes dazzling light.

And just now he clearly saw that it was pitch black, and it suddenly lit up after a few seconds, which was not at all different from the statement that the ever-bright lamp had been on for thousands of years.

But Li Zimu still said that these lamps are ever-bright lights, I don't know if he Zhuge Yinglong is blind, or if he Li Zimu is blind......

"I just said that its name is the Everlasting Lamp, I didn't say that the Everlasting Lantern can burn all the time"

Li Zimu looked at the more than 100 ever-bright lamps here and said softly.

These lamps are indeed ever-bright lamps, and the lamps in the mausoleum of Qin Shi Huang are also ever-bright lamps, these two are the same, both are lamps that use whale oil as fuel.

However, it is said to be an everlasting lamp, but it can't burn all the time, whale oil will always burn out one day, a ton of whale oil burns for 14 years, even if it is refined from a super-large whale, as lamp oil, it can burn for a maximum of 100 years, so there is no everlasting lamp that continues to burn for thousands of years.

The secret of truth lies in the air.

When they pushed open the iron door just now, the lantern was not lit immediately, because there was no oxygen in the room, and a few seconds after pushing the door open, there was oxygen in the room, and the lantern was lit.

After the Qianji Pavilion was closed, the oxygen inside was consumed due to the burning of the Everbright Lamp, so the Everbright Lantern went out by itself, and when new air came in, it burned again.

The reason why it can be burned automatically is mainly because the white phosphorus on the wick has a very low ignition point, and the ignition point of the white phosphorus that has been in contact with oxygen before is lower, and it will spontaneously combust when it encounters oxygen, so it will burn automatically.

Li Zimu approached an ever-bright lamp and looked at it carefully, the lamp oil in it was only burned a little, and this amount could be burned for at least another half a year.

The reason why the tomb robbers saw that the lamp was lit when they entered the tomb was because when they went down the tomb, the air had already entered the tomb before their speed to make the lantern burn.

So when those people entered the tomb, the lantern was already burning, creating the illusion that the lantern was burning all the time.

This is the secret of the ever-bright light.
