Maybe the coffin lid itself has a latch, and when Zhaosi put Shunfeng and the others in, the lid was secured.
As such, when the coffin fell into the water pit, the people inside should still be there.
"Senior—Senior—I'm here!" Shunfeng's shout came from beside the water pit.
I slid all the way down and stood by the water pit to see clearly. There was actually a road beside it, and a large... crocodile? Lizard? In any case, it was a four-legged reptile with Shunfeng on its head, shaking it from side to side.
Shunfeng was holding something in his hand, which was pierced into the top of the large reptile's head, firmly embedded. Shunfeng held onto it tightly to avoid being thrown off.
My skin turned green again, and I couldn't use Karmic Fire anymore. So, I had to jump onto the large reptile and attack its eyes to see if I could scare it away.
