I Started Signing In After Becoming a Demon’s Son-in-Law

My name is Liu Fan, and I transmigrated. I transmigrated to a tumultuous world where countless races stood side by side and immortals and gods existed. Starting with sign-ins in the territory of the demon race, Liu Fan will show everyone what it means to be the ultimate show-off. “What, you have an unparalleled cultivation technique?” “I have a System.” “What! You have a heaven-defying bloodline?” “I have a System.” “What, you have powerful backing?” “I have a System.” “What, you even have a childhood sweetheart?” “Sorry, I have a demon princess.” (Liu Fan: There’s no way I’m cultivating in this lifetime. I’ll just rely on the System to sign in wherever I go and coast through life. As for why I’m so strong without cultivating, do you see the words ‘ultimate show-off’ above my head?)
