Ascension is actually a prison, and the sword energy is a shackle.
Xie Jingchen, the last master of the Lingxiao Sword Sect, climbed to the top of the sword to cut through the void, but then stepped into the ancient "sky cage" - the so-called fairy world, but actually a prison to suppress the inner demons of the world.
What's even more cruel is that the natal sword energy he has tempered all his life resonates with the chains of the prison. Every sword in the past has invisibly strengthened the prison.
Those who ascended are all forced "jailers". He is determined to break the situation and joins forces with the cage-guarding goddess Yun Shu and the young master Yan Lie of the Tianyan Sword Sect who mistakenly ascended. They practice reverse sword energy as the key to uncover the millions of years of scams. He does not hesitate to lose the sword energy and put his allies into sleep, opening a true path for those who come after him.
Purpose: Knowing that the consequences of breaking the situation will be heavy, but still choose to break the situation, not to become an immortal for oneself, but to open a true path for those who come after without being deceived or enslaved. This is the great meaning of "exchanging my death for the true path of all sentient beings".
