I Guard the World by Farming

I, Ling Feng, an orphan who awakened the most useless auxiliary ability 'Spirit Planter'. When everyone thought I would hide in the rear and farm, I turned the entire battlefield into my back garden. The enemies thought I was a fragile long-range turret, until my 'Adamantine Overlord Vine' smashed their siege behemoths with one punch. They said support should stay in the backline, but I insisted on planting a sky at the front, planting all enemies into my flowerpots, adding the most fertile soil for the peace of Blue Star. — Description from novelcodex.org
