Firstly,the casting of the characters for the respective roles in the drama was apt and perfect.Kudos to the casting director/team.
The story was good in terms of the cases and the investigation processes. The disappointing part about the show is the way in which Zhan Yao protects Zhao Jue and casually converses with him despite knowing how many people he has killed and the extent of his deviousness.In fact he is more kind to and speaks more nicely with him than with Bai YuTong.
Bai Yu Tong is really protective of Zhan Yao and even in the middle of being in the battle field or dangerous missions looks out for him at the same time balancing his responsibility towards his duty exceptionally well. Any one messing with or hurting Zhan Yao will never find favor with him. On the other hand Zhan Yao knows that Zhao Jue hates Bai Yu Tong and would go to the extent of hurting him yet he continues his increasing bond with him.Zhan Yao's attitude towards Bai Yu Tong who is concerned for him is actually hurtful.He snaps at and rants at Bai YoTong even when he is being concerned for him. The friendship in the show is one-sided on Bai YuTong's part. All Zhan Yao cares about is proving his superior brain power, analytical and physiological skills and Zhan Jue. With a colleague/friend like him Bai YuTong doesn't need an enemy.
There are no actual bromance scenes/parts as such as seen in Guardian' or Killer and Healer'. Infact they describe and refer to each other as colleagues. Any friendship scenes arise out of care,love and concern on Bai YuTong's part.His loyalty to Zhan Yao is absolute.
All the other team members including the forensic doctor are great and their dedication towards their duty is commendable. Also they respect and are absolutely loyal towards Bai YuTong. They are a great and exceptional set of team members with each having their own set of skills and unlike Zhan Yao the deputy team leader none of them bonds with or is obsessed with a devious person like Zhao Jue.
