Lianfo finished his last life so he returned to being a god of the dead. Zhao comes to see him to talk and hand over the shard of Shen's soul that he managed to save and restore. Zhao fell in love with ShuShu and married her after 20 years (when she was about 40), which he felt kind of bad about because she'd been in love with Shen. However, before they married, she asked him if it was OK that she continued to pray for Shen's redemption, so that maybe his soul could find peace (to which Zhao agreed, saying that he wanted to do that too). Lianfo (I can't remember his name as a god, sorry) confirms Zhao's suspicions that ShuShu and Gujiu were both part of Tong's original soul, with most of the spirit going to Gujiu. Lianfo tells Zhao that despite ShuShu kind of being part of Tong and her first loving Shen, he shouldn't feel bad because his brother had ruined his own fate, and that it was Zhao's fate to help ShuShu move on.
Later, Lianfo finds a rabbit spirit/demon in his yard, which I believe is implied to be Tong again. This helps him decide to set Shen's soul free to reincarnate.
