Jia Yuanchun met the tragic end of Concubine Xiande's tragic death. When he opened his eyes, he returned to his boyhood and was bound to the Great Mercy and Compassionate Salvation System. In the Rongguo Mansion, the souls of the dead gathered together and wailed constantly. Only by fulfilling the wishes of the dead souls could they earn gratitude points and survive. She originally wanted to avoid the deep palace and protect her unborn child, but unexpectedly discovered that these lonely souls knew about countless secret conspiracies in the palace.

While Yuanchun was dealing with the obsessions of dead souls and investigating the unjust cases of drugging, he got acquainted with Yinzhen and was involuntarily involved in the vigorous whirlpool of the Nine Sons' succession.
