After Cao Wei, a college student, sacrificed his life to save a child, he traveled to the world of immortality and became a weed. With the support of the system and his own wisdom, he defeated monsters, upgraded, unlocked skills, and gradually evolved from a humble weed to a demon emperor grass. An Linglong, whose spiritual roots were damaged on the way, was healed, and the two walked together to fight against coveters, evil cultivators, and monsters. Cao Wei counterattacked and broke through all the way, and finally transformed into an advanced form. After going through many hardships and dangers, he grew into a generation of demon emperors, protecting the people around him.
