Please, Senior

Because of a printer, Zhou Heng and the Demon King Thaddeus had a time-traveling call. Thaddeus: My friend, become a kind and good person, and then save me by the way, okay~ Zhou Heng: emmmmmmm... Are you really a devil? Thaddeus: Of course, I can make money Zhou Heng: OK. This book is also called "Saving the Demon King Thaddeus". The introduction is weak, but you are welcome to read it.
