Primordial Chaos: Deducing the Dao, and Tongtian Scrambles to Take Me as a Disciple

A salaried worker named Liang Hong transmigrates into the Primordial World, just as Taiqing on Mount Shouyang establishes his sect and attains sainthood. By luck, he obtains vast merit and a Seventh-Grade Immortal Pill, and awakens a merit deduction system.

Dissatisfied with a fragmented saint-level cultivation method, he spends merit to deduce the heaven-defying "Little Chaotic Dao Scripture," a technique that lets him cultivate all methods and explosively increase his level when fighting above his weight class.

Because of his bizarre cultivation talent, he is taken in by the Saint Tongtian and accepted as a direct disciple, after which he takes root in the Primordial World, befriends Hongyun, forms ties with the Sanxiao, and reverses the fated outcomes of the Witch-Clan, Demon-Clan, and Investiture of the Gods tribulations.
