City Supreme Mad Son-in-Law

I, Xiao Junlin, if I am a war god, I will fight across ten thousand li!

If I am a supreme being, I will intimidate the nine provinces!

If I am a demon emperor, I will dominate the nine heavens!

Today, I am a live-in son-in-law seen by the world as a good-for-nothing, yet I am still an invincible existence!

PS: This is a story of a badass protagonist who kills anyone who refuses to obey, and stands alone above all others!
