Summary of the content: The Demon Locking Tower collapses every 2 years. This time it happened to be 2 years before the death of the Evil Sword Immortal. For the Demon Locking Tower, for Shu Mountain, and for the world, Xu Changqing was sent by the former head Qingwei to collect the seventh spirit bead - the Purple Moon Spirit Bead.
There will be some scenes between Chang Yin and Jingtian, but in the end Jingtian is still with Changqing.
