Secret Key of Immortality

I, the Living Fossil of the Universe, am now a thorny genius in the world of immortality. In the third month of squatting at the gate of the sect and eating watermelon, I realized that the world is a cage. The practice system is the bars of the cage, and ascension is the administrator's bait. And at the foot of the mountain, a "fellow fellow" from the same place as me was suppressing him - he was about to wake up. Now, the sect wants to tame me, the mysterious forces want to use me, and the "fellows" want to devour me. And I just want to know: Who built this cage? What should I do... Open a window?
