This coffin has no nails, it's just a lid, like the lid of a cookie box.
There are two pillows inside, meaning there are two corpses. If they wake up at the same time, pushing open the lid together wouldn't be difficult.
Judging by the thickness of the dust on the door handle, we can rule out the owner faking death. With such a thick layer of dust in a well-sealed space, it must have been years.
No one can fake death for a hundred years; that's not faking death, that's resurrection.
"Captain... Captain!!!" Cheng Xuelin's voice was tense and fearful, yet he kept it very low.
"What's wrong?" I walked to the door and looked down.
"Something's coming up from below!" Cheng Xuelin shouted, pinching his throat.
"You go back to the passageway." I shouted to Cheng Xuelin without lowering my voice.
From my position, I could see spots of red light in the deep well, like fireflies gathering and ascending.
