Assuming that the person who pushed open the door inside the sickroom was Chang Gu, then where did he go after entering the door?
Chen Ge knew practically nothing about this world behind the door. The experience that he had obtained from previous three-star scenarios was completely useless here, but Chang Gu was different. The man had spent years studying this specific door, and he even possessed the left eye that Chang Wenyu had taken from the School of the Afterlife.
The eye could see things that normal people could not, and possessing it was no different from possessing a cheat.
Chang Wenyu is Chang Gu's little sister. Her physical body became a vessel for scapegoats. That means that her soul should still be somewhere in this school. She won't allow anything bad to happen to her own big brother.
