I don't know if you have watched "Dragon Balls of the Demon Realm". The power of the dragon balls in it is really awesome, and wasn't there a dragon ball that disappeared in the end? And then and then... I thought, can't Dragon Balls bring the dead back to life? So... The private assumption is that the last dragon ball fell into the world of Nirvana in Fire, and then someone like Cha Muxue ate it. Even though he doesn't know how to control the Dragon Balls, he still has the ability to resurrect the dead. The time is set after the March War, and the story begins after the death of Brother Su after defeating Dayu. As for other CPs, wait until you have time~
