Mutant Beast: I Have a Cat Doppelganger

When the seals of the ancient era were undone, the world of mountains and seas was about to return to the human realm. Xiao Yun, reborn by an accident, discovered that he had a tabby cat clone that could devour and evolve. Evolve the motor system: muscles and bones become invincibly strong, and sheer force can overcome every technique. Evolve the nervous system: gain complete control over the body and make the flesh itself responsive to the mind! Evolve the respiratory system: every breath is cultivation, drawing all the world's spiritual energy into you! Evolve the digestive system: take one bite and digest it in an instant! Evolve the urinary system: purge all poisons and make the body immaculate! Evolve the circulatory system: spiritual energy enters the body and cultivation proceeds on its own! Evolve the endocrine system: evolve life itself and make the body immortal! Evolve the reproductive system: become irresistibly charming, able to captivate anyone! But when Xiao Yun stepped into the world's dark side, he froze in shock. “Wait, wasn't I supposed to be in a monster-beast production? Where did this battle between Armor Heroes come from?” The secrets of ancient times, the truth behind the Classic of Mountains and Seas, civilizations beyond the universe, and the mystery of his rebirth all unfolded before Xiao Yun, one by one.
