On the Fifteenth Day of Every Month, I Lose All My Cultivation

Lu Xiao lost all his cultivation on the fifteenth day of every month and became a mortal. That day, he was the weakest cultivator. But that day, his white tiger will fight for him. Until he made a contract with the last white tiger in the world - Bai Yao. One person and one tiger share life and death. When everyone thought he was useless, He is stepping on the enemy's head to reach the top of the Immortal Path. "You laugh at me for being useless in fifteen days, and I laugh at you for being ants all your life."
