It could be Dumbledore from beyond the grave. He might find a way to reach out and summon Harry, believing that only Harry has the potential to truly defeat Voldemort in this new, dire situation.
Harry might use his wits and the environment around him while in captivity. For example, if he's held in a place with magical artifacts, he could use them to his advantage. He could break the chains that bind him with a spell - enhanced object and then make his way to Voldemort and defeat him.
Well, it could be for power. Maybe Voldemort realizes that by saving Harry, he can gain some sort of power over him or use him as a tool in a more elaborate plan.
Perhaps it was because of the power he amassed in the process of defeating Voldemort. In the fanfic world, power can be a very scary thing to those in authority. Harry's new - found and possibly overwhelming power could have made the existing magical power structure feel threatened. So, they arrested him as a way to control and contain that power, rather than seeing him as a hero who saved the wizarding world.
In this fanfic, perhaps there could be a powerful magical artifact that summons Harry from a different time or dimension just for the purpose of facing Voldemort. The summoned Harry might have enhanced powers or knowledge. He could use new spells and strategies that he didn't have in the original story to take on Voldemort.
Some writers create these fanfics because it allows them to explore different character dynamics. When Voldemort cheats, it shows his desperation or his devious nature in a new light. And it also gives Harry a different kind of challenge to overcome, not just a physical or magical one but also a moral and strategic one. For example, if Voldemort cheats by bribing people around Harry, Harry has to decide how to deal with those who have been turned against him, whether to forgive or fight back.

This made the Qing Emperor feel fear and unease. He was worried about the threat Ye Qingmei and these weapons posed to him. Thus, the Qing Emperor decided to kill Ye Qingmei to eliminate this threat.
Lastly, the Qing Emperor's killing of Fan Xian was related to Chen Pingping's death. Chen Pingping was Fan Xian's friend. In order to take revenge on Ye Qingmei, she used the power of the Overwatch Council to gradually eliminate the people around the Qing Emperor.
