Reincarnated in another world, Lin En embarks on a heroic journey to conquer the demon world, even joining a brave team known as the "Galaxy Battleship." But the problem is, this is an all-female team! A saint who's constantly finding fault, a pressure-mongering hero who demands a court hearing for even the slightest inconvenience, and a wizard who's learned to be sarcastic before he can even speak. There's no easy win, only dirty work, endless blame, and high-pressure situations... Is it because he's the only man on the team that he has to endure even more hardships? Lin En ultimately decides to leave the team, believing he can achieve success on his own. "We can conquer the demon world without you, but thank you for your contribution to humanity, haha." Without any attempts to persuade him to stay, Lin En continues his journey to the demon world alone. But as news of the demon world spreads...
