The Northern Sea Ice Palace’s Martial God Son-in-Law

I met three miserable deaths. The first time, I was a baseball player. The second time, the third son of the Demonic Cult’s leader. In my third life, I was the youngest disciple of the Tower Lord. The life I was given anew was a return to my second life. After coming back from death once more, the Heavenly Demon spoke to me. “Go to the Northern Sea.” Three lives, none of them ever completed. That was why, in this life, I decided to live it to the very end. First things first—I’d get married. — Description from novelcodex.org
