What's wrong, why do I feel like these corpses are weird, what's weird about that?

Zhu Beichen obviously felt that some things here were unreasonable, but under the depression of the deep underground environment, his thinking became unclear and flexible.

That's right, it's the costumes. Nima, how can there be a corpse in this room wearing a bird-fish pattern robe?

Gu Ling's hobby is really strange, she collected the corpses of various dynasties and locked them here, where did she find so many people, and how many ancient tombs had to be excavated.

He ignored the fact that these standing, living corpses were all fleshy and skinny, and perhaps the blood had long since evaporated, but the flesh was still attached to the bones.

If it is a corpse that is tens or hundreds of years old, I am afraid that the skin and flesh have been crossed out, and the bones will not be left.

The layout of the surface and the spatial layout of the deep stratum are one by one, the role of the rotting corpse soil is bound to be the effect of the surface, and the layers of decaying soil and lime powder in front of the wooden house are in order to keep the corpses alive and keep the corpses alive and not rotten. The mystery in it is naturally not something that can be seen through by the white-faced Sanqian and Zhu Beichen.

"Old woman, where do you want to take us?" This is a few hundred meters underground, and if you continue to walk, you can't go back, and the metal door won't open at all. If it weren't for the fear, at least this old man named Gu Ling was the grandmother of Sanqian, Zhu Beichen wanted to put the knife directly on someone's neck and force him to take him out.

Gu Ling's figure in front of him did not pause at all, and he was still moving forward, ignoring Zhu Beichen's question.

"Go along, don't ask." Sanqian is not completely worry-free in his heart, emotionally admitting this unmasked grandmother, but emotionally he is afraid and worried. Gu Ling is too mysterious, this underground building is too weird, and the corpses imprisoned are too infiltrating.

It's, like, a huge underground tomb!

After a long while, the passage of time underground was completely confusing to the people in the walkway.

There's another door at the end!

In the light environment, San Qian and Zhu Beichen vaguely glimpsed the whole picture of this kind of door for the first time.

Under the touch of Zhu Beichen's gloved hand, it was indeed metallic. It's just that this door is a real bronze door, about three meters wide and five meters high, and the door is covered with patina. The bronze door is painted with an artistically processed beast, and under the exaggerated expression, the star of a white tiger is vividly depicted.

Well, the White Tiger Tomb! Zhu Beichen still has this bit of historical knowledge, and the general tomb depiction, the white tiger is used to guard the mausoleum. This is a typical usage of Han tombs in previous dynasties, and has been used since the Qin and Han dynasties, could this be a mausoleum?

No matter how mysterious Gu Ling is, no matter how great his ability is, it is impossible to dig out such a large underground space, and the bronze door weighing several tons is not something that can be built by a single manpower.

Sanqian shook his head, motioning for him not to touch anything underground.

There is nothing on the bronze door except for the concave and convex pattern depiction. Gu Ling's eyes glowed with cold light, first a white halo overflowed from his eyes, and then the white light faded, and the red light was like a blood moon.

The sealed bronze door seemed to be inspired, and the door body shook violently, faintly showing signs of opening. The blood pupils of Gu Ling's eyes shone more and more, constantly catalyzing the bronze door, and finally, the entire heavy bronze gate shrank and opened to the top, and wisps of dust shook off along the cracks in the bronze gate.

Zhu Beichen, who had never seen such an abnormality, took two steps back in shock, and his back was close to the glass of the small room on the left. Sanqian grabbed Zhu Beichen's palm in time, pressed his palm with a force, and signaled him to calm down.

In fact, the mood of the three thousand here is the same as Zhu Beichen. In front of the first stone gate before, San Qian and Zhu Beichen were both behind Gu Ling, and because of the visual barrier, they didn't see how she opened the bronze gate at all.

The bronze door opened slowly, and the space inside exhaled a desolate breath along the tiny gap in the bronze door, like the vicissitudes of eternity, extremely cold.

"Phew!" The two exhaled at the same time, and the space behind the door gradually revealed in front of them, an environment without lights, a dark and mysterious location, who knew what else was inside. The sight behind the first gate alone was surprising enough to make them feel resigned.

"Come in with me." The voice was very calm, and among the three people present, the only one who could keep calm and not be surprised was Gu Ling. The old man's face revealed the kindness of an ordinary old man, in short, this kind of demeanor should not be what a human being should have.

Hiss! Sanqian didn't tell himself that Gu Ling could speak Chinese, but this sentence is really true, and the pure pronunciation of Chinese is much more slippery than Sanqian.

Sanqian didn't have a trace of emotion on his face, but just hinted with his eyes that he didn't know anything.

The bronze door shrank sideways into the stone crevice above, and the ground behind the dark door suddenly lit up.

Phosphorescent is phosphorescent light!

In ancient times, phosphorescence was shrouded in mystical colors (such as a cold, dry, clear and windless winter night, and the occasional small bright spot floating between the mounds of the grave, which was thought to be a ghost fire). Some gemstones shine in dark places, such as in 1603, when a shoemaker in Bologna discovered that a local stone (containing barium sulphate) continued to glow after being moved to a dark place by sunlight. At that time, the record of phosphorescence described that Boronite was exposed to sunlight and had to be gestation for a period of time before producing light. It took centuries for people to figure out the luminescence principle and process of this phenomenon.

As the carcass of a person or animal decays, phosphorus burrows through the soil and out of the ground in the form of phosphine or phosphine gas. Phosphorus oxidizes slowly in the air, and when the surface accumulates heat up to 40 degrees Celsius, it causes spontaneous combustion, and part of the reaction energy is released in the form of light energy, which is the reason why phosphorus can emit light in dark places, which is called "phosphorescence phenomenon".

Could it be that the ancients who built this place have mastered this lighting technique in a certain year, whether it is the glow of precious stones or the spontaneous combustion of corpses.

The faint green points of light paved a phosphorescent avenue along the lines of the floor, and like the walkway behind it, it is also a bluestone brick road. Zhu Beichen somewhat understood, I don't know how many corpses there are here, so the conversion of light energy relies on the spontaneous combustion of autopsies.

Gu Ling saw that the two of them were stunned and did not move, nor did he urge, but walked behind the bronze door by himself.

The phosphorescent bluestone path was another passage that stretched straight to the depths, and the white light behind it went out in an instant, and the terrifying living corpses in the room disappeared, hiding in the darkness.

On the bluestone road behind him, what is the energy source of the white light?
