On the Day I Retired, I Went to the CEO’s Home to Break Off Our Engagement

The young heir of the capital's elite falls from grace and ends up scavenging for trash among ordinary people. His grandfather dies a violent death, leaving him nothing but a marriage contract. By chance, he enters the Outer Domain Battlefield, where he fights his way to become a Supreme God of War, feared by all. Today, he returns, and his stunning fiancée has come of age. So what if I'm a live-in son-in-law to a wealthy family? So what if she refuses to break off the engagement? My fate is mine to decide, not heaven's!
