What Happened to Yun Wu's Cultivation of Immortality?

Suppose there are two planets in the same orbit moving at the same speed, when will they meet? 1. A planet reaches the end of its life and stops moving. 2. Before the end of its life, a planet forcibly changed its trajectory for the encounter of two planets. 3. Two planets reach their critical end point at the same time. One of them has stopped and the other collided with it at the moment of meeting. The fate of the planet is doomed. Please look forward to the bloody plot of the stupid dog~ Emm, I've been obsessed with reading Yunwu fan fiction recently, and I found that I didn't get enough of it. This is a good question. As a foster father, I naturally wrote it myself. I would like to express my condolences to Master and Disciple (Jingliu) and Yan Heng (Han Danfeng Yingxing) if Lei accidentally enters, thank you.
