A mesmerizing novel of interstellar + doomsday seeking a name

A soldier once injured an attacker. When he was running away, he realized that the attacker was very similar to his missing lover (in fact), so he asked him to come over. The more he found out, the more similar he was. After all kinds of attacks, it was a little interesting. Then someone ran out to attack and said,"Don't you forget XXX!" Then, she fell into a black hole or something. She transmigrated to many years ago when Earth had just fallen into the apocalypse and met a young man. After that, she realized that both the man and the woman were jealous of her! In the end, he returned to the right era.
The background was probably during the apocalypse, when a bunch of scientific researchers with power drove their own spaceships and left those with superpowers on Earth. After they were done with their research, they tricked them into coming over and slicing them up. Therefore, the two sides started a war. After the group of people who left developed, they changed the history textbooks to fool the masses and pushed all the blame to the superpowers that they had abandoned. Therefore, they started to kill and attack.
