Two dull sounds, "poof, poof", sounded in the darkness.

Then there was a sharp pain in my back that instantly hit my whole body, and I almost lost my breath in pain.

Fortunately, the height of the fall was not very high, and I had a backpack on my back, otherwise it is really hard to imagine how many levels of cripple I would have fallen.

"Anzi, I'...... Grass...... Nima, if you fall down, you will fall, and you still drag Lao Tzu and don't let go......" Fan Ping's scolding sounded next to me.

I suddenly thought of the "people" who were now full of lights, and immediately whispered, "Shut up!" ”

I looked around warily.

It turned out that Fan Ping and I fell to the roof of a room, but I don't know which dynasty these roofs were built in, and the roof tiles were not built piece by piece, but actually a roof shape carved out of a whole stone.

"What's going on with this house and the lights?" Fan Ping, who had just sat up, said in a panic when he saw the lights around him, and moved his butt closer to me.

After giving Fan Ping a "shhh

At first glance, there was nothing in the courtyard of the house, and there was a deathly silence all around, as if there was not a trace of any living thing.

But what about the light in these houses? Only people can light the lamp......

At this time, there was some noise above my head, and when I looked up, it turned out that Xiaohua had also come down the rope.

At this time, Fan Ping came up and whispered, "Anzi, something is wrong!" Have you noticed that every house here is lit up! ”

When I looked closely, it was true, there were lights leaking through the cracks in the doors of the dozen or so rooms here, and none of the lights were extinguished.

Are they afraid of the dark?

And these houses are so peculiar that they don't even have windows.

At this time, Xiaohua had already stood on the roof, boldly took the lamp and looked around, and said: "I have been observing this place for a long time, and there is not even a ghost shadow in this house, and how can a normal person live for a long time under this kind of abyss?" ”

Fan Ping seemed to be a lot more relaxed after hearing this, and said slowly: "However, the lights in these houses can't be explained!" But the lights in these rooms are weird, don't you notice? These lights are much dimmer than normal lights. ”

Then, as if he remembered something, Fan Ping said in a hurry: "If there is no one here, will these lights ...... Was it lit here for a long time? Could this lamp be ...... Ever-bright lights? ”

I was shocked!

Because of what Fan Ping said about the ever-bright lamp, I still know better.

It was a double-layered oil lamp with a container filled with oil, a wick made of vinegar and an outer layer of water to cool the oil.

In this great hair, the oil consumed by the oil lamp is most afraid of volatilization by heat after it is ignited.

The vinegar-soaked wick not only keeps the temperature low, but the water outside the oil jar can also effectively prevent the oil temperature from rising.

But if you want to achieve a long-term effect, it is an ideal wish after all.

In the excavation of Dingling, the main hall of the mausoleum has a celadon vat, which contains wax lamp oil and a wick.

This is the lantern, but apparently the lamp went out not long after the mausoleum was closed, due to the lack of oxygen needed for combustion in the closed mausoleum.

But we are different in the dark abyss.

There was plenty of oxygen, and there was no wind in the abyss.

These houses are more equipped with ample conditions for burning lamps without windows.

In view of the current situation, I think this is the most reasonable explanation for the time being.

Fan Ping suddenly said with some grandeur: "It doesn't matter if it's an everlasting lamp, we'll know when we go down." ”

I glanced at Fan Ping with disdain.

I knew that this kid must have confirmed that there was no danger here, but that the lanterns were just scaring people, so I was anxious to go down and touch a few lanterns.

Fan Ping and I rummaged through the ropes in our backpacks and went down to the roof.

Xiaohua jumped and fell into the courtyard like a light swallow.

Then, the three of us formed a formation at the door of the house like a special patrol team attacking the house.

Xiaohua and Fan Ping stood on the left and right sides of the door, and I stood at the front of the door, dagger in hand, ready to kick in at any moment.

After gesturing "three-two-one", I kicked the door of the house.

"Crunch!"

The door was kicked open in half.

Because I didn't look closely, I kicked the door and realized that it was made of fucking stone.

Due to the force of my kick, I fell to the ground with a sharp pain in my ankle and the reaction force of the kick.

However, the two of them did not come to help me, but rushed into the house as soon as possible.

I was afraid of danger, so I basically crawled into the house.

When I entered the house, I was stunned like both of them......
