The System Makes Me Choose, So I Have to Cultivate Immortality with Wangcai

[Feel-Good Power Fantasy + Scheming + Lighthearted + Trickster + Shameless + Anti-Cliche System]

The story begins with a dog and its owner transmigrating. But the System gets the address wrong, sending them both to the demon clan's territory, and even mixes up their scripts! Bai Xiaochen gets the villain's script, while the dog gets the chosen protagonist's script!

"What? Wangcai has the bloodline of a Great Emperor? I'm stuck with a villain System???"; "System, explain yourself. That thing giving off black smoke is the Banner of Destiny? Isn't that the Banner of Ten Thousand Souls?"; "Why are all the lottery prizes for the dog? What about me?"; "Why is the technique you gave me self-destruction?"; "How is it fair that a dog yells 'Great Heavenly Dragon' and goes off to exorcise demons, while I can only cheer it on from behind with the Banner of Ten Thousand Souls???"

Bai Xiaochen: System, you might as well just kill me!!!

System: If you're useless, don't blame the road for being rough.

Wangcai: My master is the best, woof!
