The second part starts with Yandan regaining her memories and Yingyuan in mortal realm as Tangzhou along with Yumo resolving mysterious secret that was long hidden in the heavenly realm.
I really liked this part where the trio investigate few mysteries in mortal realm and also heavenly realm.
Their friendship was well portrayed and the way they investigated was really smart and cool.I also liked how they stood by each other in troubled times.
A very good second part for a depressing first part.
I highly recommend this drama.
