Xu Man is infected by a Gu, it is a special one named “You must get the first person you see when you open your eyes to tell you I love you”. If that person doesn’t say “I love you” to him within three months, then Xu Man will slowly bleed to death. Unfortunately, the first person he saw when he opened his eyes was Tang Sifeng, the leader of the Demonic Sect who notorious for killing people without blinking. It would be a hard task to make Tang Sifeng say “I love you” to him.
