Okay, this is a theme that came to mind at the last minute, I'll just play around with it╮(╯_╰)╭
The general content is that the brother controlled the girl and her Nissan traveled through time for the first time. They traveled to a chaotic fictional world with martial arts and internal power and all kinds of unscientific things. As a result, Nissan died and the girl went crazy╮(╯_╰)╭ She began to study various resurrection methods, and finally a god came and said that as long as she XXXXXXX (forcibly silenced), she could resurrect her Nissan╮(╯_╰)╭Then the girl began her journey to conquer the world
Popular science here: Brother's control does not mean that he wants to have children for his brother, nor does it mean that he cannot get married [but in my brother's heart, I will always be his closest family member! ! So this is still a no-CP
