After Being Reincarnated as a Pig, I Became a Mythical Beast Through Involution

The foundation of ten thousand years was destroyed by my hands, and the sins in my life made the official of the underworld furious and cast me into the animal realm. When he opened his eyes again, he was curled up in the sow's belly, becoming a piglet with memories of his past life in his womb. In the darkness, I was horrified to hear my brothers and sisters making noises, but I could not open my mouth to angrily rebuke these stupid pigs. After I was born, I tried my best to be a special pig, and was finally selected as a pet by a blind monk passing by. I thought I was embracing a cultivator, but unexpectedly, this poor cultivator forced me to make elixirs and practice weird techniques every day. Until one day, I couldn't bear it anymore and kicked his precious pill furnace with a pig's trotters. From then on, he embarked on the road of escape. The legend of becoming a mythical beast is about to begin. Adventure, practice, transformation... I vow to find the legendary underworld.
