The Protagonist Has a Deer [Book Transmigration]

Mulian is a divine deer who secretly took human form. His blood is full of vitality, able to revive withered trees and make flowers and plants grow wildly. He mingled among humans, carefully guarding his secret all this time. Until one day, he transmigrated into a book as a minor cannon-fodder character. The pitiful protagonist, whose blood could make all living things wither, was lying right beside him. Mulian: We complement each other perfectly. How about we team up? Protagonist: If this stupid deer dares to hold me back, I'll eat it. Later: Forget it. I'll keep it around. Possibly sweet and kind, but not foolish, cannon fodder X possibly lovesick and melodramatic protagonist Theme: Treat others with kindness, and kindness will be returned to you.
