The parallel world of Britain and the United States collapsed due to time travellers. Before the collapse, Loki and Thor's son Nolan was sent to the parallel world by Loki.
The Chitauri invasion had just ended in the new world, and Avengers Tower was smashed into the new world as soon as they arrived.
Thor took Loki back to Asgard. Noren didn't go to the Rainbow Bridge and walked together. When he opened his eyes, he found a group of familiar uncles and aunts.
The Avengers all had toothaches as they looked at the little meatballs in front of them who looked like the pair of god brothers and claimed to be the sons of the God of Thunder and the God of Evil.
Purpose: I hope the superheroes in the parallel world can have a beautiful and happy life
