All the Worlds in the Well

On a rainy night in Qinglan Mountain, handyman Shen Yan was expelled from the sect. He was silenced that night and fell into a dry well that should not exist. Seven shadows on the wall at the bottom of the well, a line of "don't look up" rules, and an ancient fragment lodged in his body dragged him into the world of the secret realm of the heavens. In his eyes, the secret realm is never a dead thing - the rules are as alive as breathing, just waiting for him to understand them. But the deeper he goes, the more he discovers: the secret realm is not a chance, but a test paper; the person who asked the question is not the way of heaven, but the "keeper of the boundary" who has disappeared long ago. The first question on the examination paper was written on his way here.
