Immortality Debt Book

In Qinghuai Immortal Sect, you need to sign a contract to practice, you need to pay debts for elixirs, and even your life span can be accounted for. Shen Yan, the scribe of the longevity deed room, discovered that his life span had been rewritten, and an extra sum of money was added to his name out of thin air to cover his longevity. Everyone said that the account was correct, but he was the only one who could see the missing pages that had been dug out of the contract. In order to survive, he started from a wrong account and pursued the Dan debt, sect and earth line general ledger. But every time he made a correction, he got closer to the accounting system in which the bottom class paid for the life of the immortal, and he also pushed himself into the next debt.
