A Refugee from the Start, I Use Card Collecting to Crush All the Buddhas

Zhang Tian transmigrates to a world overrun by demons, where humans are livestock and the people suffer miserably. When he opens his eyes, he finds himself in the body of a starving refugee on the brink of death. A System arrives, and he awakens the Taoist Collection System. He thinks this will be the peak of his life, only to discover that the world worships Buddhism and Taoism above all else. Every other path of cultivation is dismissed as heresy, and Taoism seems never to have existed at all: it cannot be spoken of or even named. Watch as Zhang Tian creates a ray of light for Taoism from the humblest beginnings. [Congratulations, Host, you have collected a damaged stone stele of Laozi riding an ox. Collection points +30.
