Defensive Spirit For Everyone: My Spiritual Pet Is a Female Zombie

After an accident, Ye Ling transmigrated to a fantastical world where everyone had spirit-taming powers. He managed to activate the Spirit Taming System, which allows him to see evolutionary paths invisible to normal people. For every level he gains, he can tame a new spirit-pet. Ye Ling's first spirit-pet turns out to be a zombie, which seems like the weakest pet to everyone else, but Ye Ling can see that his zombie is a super spirit-pet! (Source: Kuaikan, translated)
