Who sent the last message Zhuang received?

The text message reads: "Congratulations, because you insisted and you did it." It has been hinted in the previous plot that in Memory Fragments, when Zhuang taught Zhuang to hold his breath on the rooftop, Zhuang once said to Zhuang, "As long as you insist, you can do it." So it is Zhuang Baiyao.

"The Gate of Rebirth" is the first tomb-robbing mystery drama in China directed by Yang Dong, starring Zhang Yi, Feng Wenjuan, Fan Shiran and Lan.
