The Regressed Mercenary Has a Plan, by JJJSSS and Gold Haeng, is a WEBTOON Original updating every Wednesday. Cecil Perdium, the Mercenary King, is killed in battle before he can avenge his family, and as he dies he learns that Duke Delphine, who brought the family down, did not act alone.
Then he wakes up as his teenage self. This time he has the years and none of the assets. He has to overturn a poor reputation and rebuild his strength, starting from a house whose soldiers and knights are defecting because of the conditions they are kept in. It uses the grammar of a regression story, with most of the weight on rebuilding an organisation.
