Tennis: Mifune Came to Work at U17

Lin Feng traveled through the world of tennis kings and became a junior high school tennis player. Unexpectedly, he was recruited by Mifune Irido as a member of the U17 First Army. At the same time, the work system was awakened. As long as you complete the problems you encounter at work, you can get rewards! "Oh?! My boss is Mifune? Are there any rewards?" "Don't worry, Mifune Boss, you don't have to worry about U17 winning the championship anymore!" Mifune: "I asked you to recruit junior high school students, but I didn't ask you to form the first junior high school army!" "Didn't I say not to be impulsive during the expedition? Why did I defeat all the players from other countries?!" "Ah?! You were asked to take charge of the U17, why did you establish the new U17?!" Lin Feng: "Don't worry, Boss Mifune. Although I am my own boss now, you will always be a stepping stone in my heart!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
