Ye desperately recalled the fragments of conversations between him and Fuzi, and the ghostly events, generally inferring that this was related to another past incident of his.

Back then, Fuzi also discovered this unknown space under the old archives building, suspected to be a former Japanese military laboratory. Before he could report it, he was killed by Principal Dai in the laboratory.

Afraid of the laboratory being exposed, Principal Dai dragged Fuzi's body into this air-raid shelter and sealed it in a room, later guiding the police to find it.

Due to the obsession of the victim affected by the formation, Fuzi's soul wandered around the campus.

Twenty years later, he witnessed Grandma Hua's true soul being released and noticed her soul entering Ye's body.

But because he was killed by a sneak attack, Fuzi did not know the true culprit's motives and circumstances, so he used the heavy Yin energy of the "Gathering Yin Sea" to reappear, pretending to be a roommate, guiding Ye step by step into the mystery to uncover the truth.

Eventually, after defeating the evil Yin-Yang master of the cult, Ye found evidence of the Japanese bacteriological experiments.

And those victims, including Fuzi, finally released their resentment and left.

Over the weekend, Ye bought a box of spicy strips and placed them in front of Fuzi's grave.

"Not long, my good brother, you can rest in peace now."

Tears in his eyes, Ye seemed to see Fuzi's smile.
