To prove that he loves Ye Sichen, Gu Li is willing to descend into the eighteenth level of hell to cleanse his soul.
He thinks this will be enough to prove that he has no feelings for anyone but Ye Sichen.
Instead, all he gets is Lin Zhi’s scheming and Ye Sichen’s mistrust.
After enduring every kind of torture, Gu Li’s fragile soul is ultimately scattered. Only then does Ye Sichen realize he wronged him.
To make amends for the pain he caused Gu Li, Ye Sichen searches all three realms for the reincarnation herb and returns to the past, never expecting Gu Li to have been reborn too. From then on, he sets out to win Gu Li back.
