Transformed into a World Tree, I Was Handed over to the Country!

After traveling to the end of the world and becoming a small sapling that could not move, Chen Yu originally thought he would be finished. Fortunately, there is an "environmental protection system". Others rely on killing monsters to evolve, but my evolution depends on "picking up garbage" - purifying the soil, cleaning up waste water, absorbing waste gas... At the beginning, he was surrounded by beautiful scientists, and he thought he was going to be sliced and studied. Su Xiaoyun: "It is purifying the land. This is an ecological miracle!" Me: (nodding) Yes, give me some nuclear waste as fertilizer, it will grow faster! Military: "Report! A highly toxic leak occurred in the western suburbs chemical plant!" Me: (stretching out the roots) Don't panic, I'll suck it. Military: "Report! A 100-meter giant beast crawled out of the deep sea!" Me: (stretching out the roots) Don't panic, I'll tie them up. Yingjiang: "Report! Our mecha has a panda head painted on it..." Me: (withdrawing the roots) Don't panic, I drew it. When the whole world thought that Xia State was secretly cultivating some ultimate weapon, it was discovered that they were only seriously engaged in greening. It's just... This tree seems to be a little too green? When my roots spread all over the world, the canopy of the tree covered the stars, and the angels and gods I gave birth to stood on the branches, the whole world was silent. "We promised to do environmental protection, but why did you become the savior?"
