Devour It, Chomper

A high school boy died and was reborn as a chomper. He originally thought he could bask in the sun, drink water and lie down every day, but he discovered that as a plant from another world, he was in danger of being eaten by monsters or poached by hunters to refine medicine at any time. Fortunately, he has his own "flower" system, which continuously integrates the characteristics of other plants, and eventually evolved into the guardian immortal plant of the Giant Continent.
