Isekai Reborn as a Broke Lord: I Married 3 Debt-Loaded Wives on Day One

Bro died gaming and got reborn as the most useless grandson in an ancient China warlord clan — zero rank, zero skills, three debt-loaded wives nobody else wanted. Everyone thought he was cooked. Turns out his "worthless" bamboo land is sitting on an iron mine, and cheap wine + future-brain chemistry = an entire empire in 3 days. This is a full manhwa recap for anyone into isekai reincarnation, op mc business tycoon arcs, and slow-burn revenge stories. Part 1 of 3 — the setup before the war starts.
