My Senior Brother Is a Retired Swordsman

Su Yun is a retired sword master. When he was young, he did too many great things incognito, and became known as the unknown swordsman. Enemies are flying all over the sky, and thousands of thieves are on your mind. If the chess piece is wrong, the nine tribes will be happy. Su Yun had to be careful. When he was retiring, his master in the mortal realm wanted to travel far away and approached him, hoping that Su Yun could manage the medicine field on his behalf. Su Yun readily agreed. Just when he thought it would be good to spend his retirement life like this, a junior sister appeared on the mountain where he was... This is a really bad start. A hundred years later, Su Yun looked at the nine junior sisters following him and couldn't help but sigh: The rolling Yangtze River flows eastward, and the waves wash away the heroes.
