The Dark Blade of Empress Xuanbing's Merits

One sentence summary: Lin Wan transformed into an ant at the bottom of the world of cultivation and was bound to the "Tiandao Merit System". As long as he does good deeds, he can increase his cultivation level. In order to survive in the cruel world of cultivation, he was forced to earn merits frantically - practicing Dharma for demons, helping the demon king mediate family conflicts, and mediating disputes between Taoists and Taoists for the leader of the righteous path. Until one day, he accidentally brushed on the head of the Ice Mountain Empress, the number one in the world of cultivation. From then on, he just wanted to survive, and was involved in the Shura field that even the heavens trembled.
