Suspect

"So this is the acid lake ..." Liu Yang murmured. He picked up a rock and threw it into the lake.

The stone floated for a few moments before sinking into the acid, but it was impossible to know whether the stone melted or not.

Pang !!!!! Crack !!!!

Liu Yang punched the floor and pulled out a piece of stone big enough to hold.

When the stone was placed in the acid, Liu Yang held it for a few seconds before taking it out.

The stone did not suffer any corrosion or anything like that. This proves that the stone stomach was strong enough to withstand the corrosion of the acid.

"I see…"

(These rocks look like a person's stomach wall. This protects the body to prevent the acid from leaking. But can a stone boat float in the acid?) Liu Yang was unsure if he could use a boat and navigate the lake.

Splash !!!!
