What Just Happened?

Yuan and the others stepped into the inner area of the tomb after mentally preparing themselves. 

The second their feet touched the ground in the inner area, they felt the atmosphere instantly change, and it suddenly felt as though they'd entered another world— a world that is filled with death and a place that humans don't belong.

"This is worse than I thought…" Tian Suyin muttered as she subconsciously pinched her nose to avoid the smell.

"What the… Where did this stench come from? It wasn't there just a second ago!" Tian Yanyu was baffled.

"You cannot see it, but the inner area and the outer area are separated by an invisible boundary. In fact, they can be considered as their own world." Jin Xi said.

"No wonder…" Tian Yanyu mumbled.

"You guys should block the smell with your spiritual energy." Yuan said to them.
