For me...
1. Hou Ming Hao (Zhao Yuan Zhou)
- all scenes where he used his iconic 'one-word spell'
- sword dance scene with TJR
- when he locked himself in his peach blossom house and have conversation with his inner demon (himself) then his dream was shown
- when he reunited with Wen Xiao after gaining conciousness
- the last scene when he slapped himself and hesitated
2. Chen Du Ling (Wen Xiao)
- her fight scene with the rabbit demon
- her scene when she became evil wen xiao
- when she went 300 years inside the sundial
- the moment where she answered li lun's questions smartly
3. Zheng Xuan (Ying Lei)
- i love all his scenes, he is a precious sunshine
4. Yan An (Li Lun)
- last scene with the short hair
