Xu Yi tracked the shoe prints up the staircase, striding forward with the pounding sound of his footsteps on the wooden stairs, like beating drums.
To save time, Xu Yi no longer cared about concealing his presence.
During the ascent, Xu Yi used the Symbiotic Eye to check the situation in the Treasure Box space.
He finally saw the true form of the Evil Spirit, its body charred black, likely having suffered a great fire in life.
Dark, gel-like substance surged from the crevices of the Evil Spirit's body, not dripping to the ground but sliding over the Evil Spirit continuously as if alive.
The Evil Spirit before him was his initial target.
The exorcism request described the Evil Spirit as: "It moves only in darkness and never appears under the light."
This aligned perfectly with Xu Yi's impression of the term "Dark Stealth."
