The Bureau of Exorcism: Cannon Fodder from the Start?

Others cultivate immortality through techniques, but Deng Junyi cultivates through contracts. Deng Junyi is the lowest-level copying clerk in the Bureau of Exorcism, with no martial power, and is laughed at by his colleagues. But he has a pair of eyes that do not belong to this world: the Eyes of Rules. He can see the forgotten underlying code of this world, the original contracts signed by ancient gods and all races. A demon beast harms people? First check the contract terms. A demon god demands a life? Then check the breach of contract clauses. When everyone draws their swords, he pulls out an overnight drafted document: "According to Article 7, Clause 3 of the Ancient Covenant, your recovery action has exceeded the authorized scope. Please return." From a bookworm sent to die to a 'rule-keeper' who makes even gods and demons sit down and negotiate with him, Su Jin proves one thing: fists can only make you bow, but only rules can make you kneel!
