Shocking! I've Become the Debt Collector for the Heaven and Earth Bank

Xu Xianzhi obtains a mysterious Heaven and Earth Bank, but strangely, the bank has absolutely nothing inside. No divine weapons, no treasures, only one debt after another!!!!

The Eternal Immortal King owes the Heaven and Earth Bank one top-grade immortal artifact, to be repaid with two artifacts in two thousand years. If payment is overdue, one divine artifact will be added every thousand years!

The Fairy of Guanghan owes the Heaven and Earth Bank a peerless beauty, to be repaid in ten thousand years. If payment is overdue, she will pay with her life!

The Eternal Venerable borrowed ten thousand years of life from the Heaven and Earth Bank to break through to the next realm. After succeeding, he promised to repay tenfold, meaning one hundred thousand years of life. If payment is overdue, the debt will increase tenfold!

Looking at these inexplicable debts and the empty Heaven and Earth Bank, Xu Xianzhi resolves to find every debtor and collect their overdue debts!
