I Became the Creditor of All the Bosses in the World

Boss, you begged me to borrow an immortal weapon back then, saying it would only cost you a thousand years and a spiritual vein. Now I don't want to pay the interest, and I don't want to pay back the magic weapon. Should I give an explanation? Immortal Emperor, you signed a contract with us tens of thousands of years ago. After helping you become an Immortal Emperor, you will be controlled by us for thousands of years. Why do you want to regret it now? Still want to kill me? I'm holding you in my mouth! How can there be any reason in the world not to pay back the money you owe? All the worlds are in debt to me, Lin Daoran, and you still want to run away? Don't talk about your boss, even if the Immortal Emperor comes, if you want to owe debts without repaying... Then let's die together!
