MTL - Marrying The Villain - Chapter 53 ran into

What would you do if your planet ceased to exist after a nap?

This stands at the forefront of strategy guides to Life (a shitty video game)!

A War Without Casualties.The Republic of San Magnolia has long been under attack from the neighbouring Giadian Empire’s army of unmanned drones known as the Legion. After years of painstaking research, the Republic finally developed autonomous drones of their own, turning the one-sided struggle into a war without casualties-or at least, that’s what the government claims.In truth, there is no such thing as a bloodless war. Beyond the fortified walls protecting the eighty-five Republic territories lies the “nonexistent” Eighty-Sixth Sector. The young men and women of this forsaken land are branded the Eighty-Six and, stripped of their humanity, pilot the “unmanned” weapons into battle…Shin is the leader of a squadron of eighty-sixers. Lena is a “handler” who commands the detachment from the remote rear with the help of special communication technology.The farewell story of the severe and sad struggle of these two begins!

Elena, who spent her entire life as a cold-blooded female knight to avenge her family, ended up dying without claiming her revenge. When she opened her eyes she found that she went back into the past. By day she was a lady in a dress, and at night she carried a sword to change history and prevent her family’s destruction.
