Occult Pact

Since the contract was created by the gods, why did the ancient gods who controlled the laws fall? Since the ancient gods have fallen, why can a contract still deprive them of everything in the world? If the contract in this world is just a piece of paper, then in a world with a real contract, does the achievement of the contract mean eternal secrets, order and rules? Corruption, scarlet, holiness... Black Tide, Blood Moon, Falling... Disciple, rank, extraordinary... Magic Tower, Warcraft, Demon Realm... How many crises have intersected with me, how many classics and secrets have I mastered, how many entrusted tasks have I completed, and how many secrets and waves are embedded in me?
