Jiang Han burrowed underground, reaching the vicinity of Yuehu Town, but he didn't enter the area covered by the Fierce Fire Formation.

It wasn't that he didn't want to go in, but there were many formation patterns beneath the Fierce Fire Formation preventing his entry.

He felt that if he forcibly broke through those formation patterns, it would trigger the grand formation.

Jiang Han didn't know what the outcome would be if the grand formation was triggered, as he wasn't familiar with formation patterns and didn't dare to act rashly.
