Shen Wei is the college prof who is also the Black Cloaked Envoy from the region below the earth where the other race agreed to live to keep the peace. They're changing their minds and coming up.
Zhao Yunlan, the head of a criminal division, investigates special crimes. For 10,000 years, the long-lived Shen Wei has been keeping an eye on his friend thru his friend's various lifetimes. Then they meet in person on a case when Zhao Yunlan considers Shen Wei a suspect in a series of crimes.
Shen Wei's Kryptonite is the fact that he uses the Hallows (probably thanks due to Harry Potter) to transfer his life force to those who are injured. Which means he becomes weaker and weaker throughout the series as he helps everyone he can.
PING to a Chinese drama music video
I also put up a music video I did a few days ago of a fandom artist friend whose art I videotaped back in 1988. She actually was invited to do John Wayne for a Valor magazine cover. Fan art can be marvelous.
Sounds interesting, I will check this out.
