After the death of the Demon King of Destruction, I became his only legal heir. The inheritance includes 30,000 demon soldiers, seven demon cities, a set of demon castles - and the debt he owes to 998 lives. The lawyer read out the will: "Pay at least one item every quarter, and you can inherit the entire inheritance after paying off." I asked how to pay it back, and the brave man holding a sword at the door smiled: "Article 1: Kill me, and you can pay for the debt of one life." And I looked through the account book left by my father and found that he was going bankrupt.
