After calming down, Lin Congfeng got up from the ground, put on his coat first, and sorted out the equipment on his body.

The temperature here was too low, and if he didn't wear clothes, the low temperature would take away most of the heat in his body.

Lin Congfeng didn't look at the coffin first, but took a flashlight to observe around the room.

After a while, his face was overjoyed, and he seemed to have found what he was hoping to find.

He quickly walked to a corner of the room and pulled out a fire fold.

Lin Congfeng was looking for a wall lamp in the room.

In the underground where there is no light source, whether it is construction or other things, light is a must.

Electricity to provide a light source is a very unlikely event, the amount of work required is too large, and it is also unstable.

The most primitive lighting method is the best choice, and the facts have proved Lin Congfeng's conjecture.

He tried to light the wall lamp with a fire fold, and sure enough, the things made by the family were reliable, and the lamp oil in it could still be used.

Generally speaking, the lamp oil used by the family can be stored for more than one jiazi.

Not only does it hardly produce smoke when burned, but it also has a faint smell.

Compared with the fire fold, the lighting range of the wall lamp is very large, and the room suddenly appears to be lit up.

Immediately afterwards, Lin Congfeng found five more wall lamps, and after all of them were lit, the entire room was illuminated.

The setting of the wall lamp is very reasonable, ensuring that there is no shadow in the room, and Lin Congfeng's heart instantly calmed down.

In any case, light can give a great sense of security.

And after calming down, Lin Congfeng also began to carefully observe the entire room.

The room is not big, only about fifty square meters, originally Lin Congfeng thought that there must be at least hundreds of square meters here.

A room of about fifty square meters with such an exaggerated iron door really looks incongruous.

There was nothing else in the whole room except for a coffin, which was not too unexpected for Lin Congfeng.

There must be something particularly important and dangerous in the room, and there are obviously not too many items that can reach this level.

Lin Congfeng squatted down and carefully touched the ground with his hands.

The ground is not flat, but has complex textures.

The lines weren't obvious, so he didn't notice it when he stepped on it before.

The floor of the entire room was covered with this pattern, and Lin Congfeng guessed that this was a formation.

The reason why the room was built so big was not because of how many things needed to be placed in it, but because it was prepared for the formation.

"What the hell is in there?"

Lin Congfeng muttered to himself.

There was nothing special about the coffin, except that it was not nailed, but simply sealed with a red rune paper.

Lin Congfeng was already surprised, there was such a big formation below, what was there to make a fuss about pasting a few pieces of rune paper on the coffin.

It's not that he hasn't seen a particularly evil coffin, but this coffin feels weird to him, indescribably weird.

Lin Congfeng had a feeling that he wanted to open the coffin.

As soon as the idea came to him, his brain buzzed.

Lin Congfeng hurriedly took a few steps back and stayed away from the coffin, he was afraid that he would not be able to control himself from opening the coffin.

He didn't know exactly what was in it, but he was sure that the coffin must be something remarkable.

Once released, it is far from something that can be solved by a few dead people.
