A Genius Professor Transmigrates, Awakens the Ultraman System, and Becomes a Live-In Son-in-Law

I was a child prodigy professor, but transmigrated into the son of a high-ranking official! I spend my days in drunken revelry, then somehow end up as a live-in son-in-law and royal consort. At a critical moment, from the start, I get caught up in an earth-shattering plot: the eldest princess abducts the emperor and beheads him! That’s when I awaken the Ultraman System. I’m Xiao Yang. Tianyun Kingdom is my home. I love Tianyun Kingdom. I’m going to become Ultraman, defeat the monsters, and protect my country.
