A forest of trees ?

He was strangled on the ground by the grasses and vines which were tied to his feet and hands like ropes. He amasses some strength in his body to break free from grassy restraints. 

After breaking the soft constraints he stood up to check on his condition and more particularly where he was right now. Surprisingly his body was healed very much from the injuries. Only dull pain was left in some parts of his body.

He noticed the amount of elemental energy was back to normal in his body whereas nether energy was back to being dormant lying in his veins. He took a deep look around to notice where he was.

There were trees and trees all around him, lush jungle consisting of vastly outgrown bushes and shrubs and grass-covered forest floor. There was hardly a place left where bare soil is peeking from the thick vegetation.

"This was a f*cking dense Jungle!"
