Lin Yun determined the frequency of activity at this entrance by the disturbed dust and sand, which had been tainted with a touch of black due to the leakage of Demonic Qi whenever the Formation was activated, using the power of the Demon.
Unsure of what dangers lay ahead, Lin Yun lit a torch and continued to advance through the Underground Palace.
This was the interior of the base, frequently used, so there weren't many mechanisms inside the corridor. Perhaps it was designed with the idea that anyone who managed to get in would trigger the Formation at the entrance, which would destroy the Underground Palace.
However, the doorways along the lengthy corridor were still protected by Formation.
Clearly inscribed above were the words Refinery Room, Pill Concoction Room, Talisman Crafting Room...
Lin Yun was quite interested in these rooms, but using the Nine Heavens Divine Thunder was too exhausting. He had been in continuous battle for too long and was now slightly overwhelmed.
