Yun Che will lose everything he has held dear. There are already signs of this: first, with the everlasting stone he has given to wuxin (which i am guessing will find his way back to Yun Che), and the necklace she gave to him. Probably those things will be the only memories left to remember them. Also was the xiao lie birthday which i imagine will be the final time they are all reunited.
Now his greatest backing is lost, and the top shots of the three divine regions are reunited in the eastern. Chaos and death are coming soon to Yun Che and his family.
After he loses everything, he will receive a huge setback in his soul distorting his personality and being. Mars describes this corruption as Blackening, we can see some of this with lingxi’s illusion of Yun Che is going to the darkness.
Then he will find his way - probably with the illusory stone - to the north god region where he will reach divine master … and then.
Yun Che will raise himself as the EVIL MONARCH ruler of the north divine region and begin the war Devil vs God II. And just as was mention in chapter 1486, he will not rest until one side died…
