"The underground palace of Qin Shi Huang, the first emperor of the ages, can finally reveal what is inside!"

As soon as the door of the underground palace was opened, this beam of light was very confusing.

"After entering the dungeon, you can't act rashly!" Li Yunlong looked at everyone and said: "This Mausoleum of Qin Shi Huang is not an ordinary imperial mausoleum, there may be a lot of organs inside, you must be careful in everything!" ”

"Yes!" Everyone nodded.

Li Yunlong took a deep breath, then stretched out a foot, stepped into the door of the underground palace, and then began to walk down the stairs step by step down the underground palace.

Xu Yihang, Xu Erhang, and Wei Dayong followed closely behind Li Yunlong, stepped into the stairs of this underground palace, and began to walk down step by step.

The further down the dungeon, the brighter this light becomes!

At the end of the 12 staircases, you can see a passage with rocky walls on both sides, and some stones are placed on the stone walls.

Li Yunlong, who was walking in the front, looked at the stones on both sides of the passage, squatted down, picked it up and looked at it, and then said with a smile: "I finally know the reason for the glow, it turns out that these stones are these!" ”

"What kind of stone is this, which can shine for more than 2,000 years?" Xu Yihang looked at the stones on both sides of the passage, all of which were emitting this faint light.

Although the light was very dim, the light from so many stones gathered together was unusually bright in this dark place.

The light at the entrance of the dungeon should come from here!

Li Yunlong took a large number of the stones, and said after a while: "This should be fluorite, fluorite is also known as fluorite, fluorite powder, fluorite powder." is a mineral. ”

Fluorite is an alkaline diluent, so named because when fluorite contains some rare earth elements, it emits phosphorescence. However, the production of this phosphorescent fluorite is not large.

Night pearls, this is a very magical gemstone beads, but it can be said that the vast majority of night pearls are made of fluorite. Due to the large crystals of fluorite, fluorite night pearls can be found in very large volumes.

"There will be rare earth elements in these fluorites, and chemical reactions will occur in them, because of rare earth elements, these fluorites can emit a long-term light, this light is relatively weak, invisible during the day, and very bright at night~."

Li Yunlong held the smooth fluorite in his hand, and said lightly: "These fluorites are about the same size, if they are placed in ancient times, this is definitely a priceless treasure, Qin Shi Huang must have looted a lot of treasures after destroying the Six Kingdoms, and it can be seen that this fluorite is the ancient night pearl paving the road!" ”

"This is indeed a tyrant!" Xu Yihang said lightly: "Such a luxury is estimated to be unmatched!" ”

"He's a tyrant, but he's an emperor through the ages!" Li Yunlong said in a deep voice: "If it weren't for him, our entire country might be torn apart!" ”

Xu Yihang was stunned, and then nodded as if he didn't understand.

The whole road section paved with the night pearl is not very short, and there is no end in sight, the whole passage is illuminated by the night pearl in all colors, bright and abnormal, and it looks very spectacular.

"Be careful with everything!" Li Yunlong advised again.

Eyes see six ways, ears listen to eight directions!

This is Li Yunlong's current state.

Although the entire road is paved with the Night Pearl, which is very luxurious, no one knows if there will be traps, after all, a generation of emperors like Qin Shi Huang would not build their own mausoleums so simply!

"Babbling and Booming"

As he walked, Li Yunlong suddenly heard a sound like a stream of water, but the sound was lower than the sound of the stream, and it should be a medium liquid.

"Wait, do you hear any sounds?" Li Yunlong said.

When Wei Dayong heard this, he also spoke: "Yes, division commander, I also heard the sound, but where did this sound of water come from?" ”

Xu Erhang said: "This is likely to be the sound of water flowing in the underground river?" ”

"No, the sound of the water should be clearer than this!" Xu Yihang's face became solemn and analyzed: "This should be a liquid heavier than water flowing!" ”

"It's mercury!" Li Yunlong's expression was also very solemn.

The famous historian Sima Qian proved that the mercury in the tomb of Qin Shi Huang was recorded, and Li Yunlong, who traveled from modern times, also knew that there was a large amount of mercury in this Qin Shi Huang Mausoleum!

During the Spring and Autumn Period and the Warring States Period, it was a common practice to place mercury in the mausoleum, such as the tomb of King Qi and the tomb of King Wu. During the Spring and Autumn Period and the Warring States Period, ancient alchemists had already mastered the method of heating mercury sulfide to obtain mercury.

Qin Shi Huang's purpose in the mausoleum was to use mercury as a river and sea, not only to create a magnificent natural landscape, but also to make the buried corpses and burial goods remain undecomposed for a long time.

If this is instructed, Li Yunlong has nothing to worry about, but this mercury is highly toxic and highly volatile at room temperature, so the mercury in the underground palace can also poison the captain who dares to break in.

The sound of water that everyone hears now is probably the sound of mercury flowing.

“.. This mercury is mercury, which is easy to volatilize and disperse into the air (Zhao De's) at room temperature, which will cause us to die of poison! Li Yunlong turned to look at everyone and said, "And according to my estimates, the mercury in this underground palace may reach as much as 100 tons!" ”

One million tons of mercury, this is a very terrifying data, and in the Qin Dynasty, the mercury mines in the southeast of Sichuan need to cross the Yangtze River, trace the Jialing River up, go to Bashan, cross the Han River, and pass through thousands of miles of plank roads before they can be transported to Guanzhong. And transporting 100 tons of mercury to Qinling, the hardships of the project can be imagined.

"A million tons of mercury?"

Xu Yihang, Xu Erhang, and Wei Dayong were all stunned, so how did they enter the underground palace?
