What is the interpretation of this verse? "There is no way to climb the green screen. I and the withered vine are both half immortals."

The top of the mountain (Fan Chengda)

There is no way to climb the green screen, and the withered vine and I are both half immortals. Don't dare to raise your voice, the sky is so close, the world is indifferent but cold smoke.

The general meaning is that there is no road on the green screen, but I will work hard to climb it. When I reach the edge, I, the withered vine, seem to have occupied half of the fairy energy!
