Lin Xuan, an ordinary Taoist boy under Hongjun, accidentally discovered a fatal loophole in the laws of heaven and earth (the saint's calculation caused the imbalance of luck in the ancient times), and was targeted by the dark villain hidden behind the scenes (former friend, now the quasi-sage Chuhe who fell for the fragments of the law). At the critical moment, the mysterious goddess of revenge Su Qing appears to help, and the two work together to reveal the truth about the saint's plan - it turns out that the way of heaven has been tampered with by the saint in order to consolidate his rule. Lin Xuan relied on his clever layout to pretend to be a pig, eat a tiger and slap the villain's minions in the face, while collecting fragments of laws and gradually uncovering the secrets of the ancient world (such as the fall of spiritual roots, the reincarnation of saints, and the backlash of heaven). As the plot progresses, Su Qing's identity is exposed (in his previous life, he was the "Chaos Qinglian", the spiritual root of heaven and earth. He was killed because he refused to be controlled by the saint and was reincarnated as the goddess of revenge). The two of them work together to find the key to reshaping the law - the Chaos Spirit Pearl. In the end, Lin Xuan used the collected law fragments, combined with the power of Su Qing's spiritual roots, to break the old laws, reshape the new order of heaven and earth, end the rule of saints, and open a new era in the final battle with the blackened villain Chu He (who has merged part of the power of heaven).
