Who's Knocking on a Wooden Fish at the Military Academy?! [Mecha]

Dao An, a little monk from the Qing Dynasty, is transported by an explosion to a galactic age tens of thousands of years in the future. There, she enrolls at Saiyuaner Military Academy and becomes an honored combat specialist. The only thing is, this combat specialist has a very strange personality. Her mood swings from pleasant to foul, and her favorite thing to do is knock on a wooden fish drum. During the five-person team competition in military training, she is randomly assigned teammates. They dismiss her as too weak to be any help. She says nothing, until she uses her spiritual power while tapping her wooden fish drum to wipe out everyone on the field. Only then do her teammates realize how great she is. During the military academy league, a member of Saiyuaner Military Academy's main team is badly injured, and Dao An takes their place, wooden fish drum in hand. The audience is baffled by her tactics, until they see her unleash her spiritual power. Wait, isn't this student in the combat division? How does she have the spiritual control abilities of the command division? Another time, the mecha engineer on Saiyuaner Military Academy's main team is taken out. The opposing team laughs gleefully behind their backs. Dao An takes out her wooden fish drum, thinks for a moment, then puts it away and repairs her teammates' mechas instead. Wait, is this student studying mecha engineering too? Yet another time, all the main teams from the military academies face a poisoning crisis. The audience comments: Dao An's mother is a doctor, so there's a good chance Dao An is also studying medicine. In other words, Dao An is a promising all-rounder. Comrades, as long as Dao An stands, Saiyuaner Military Academy will prevail! Then they discover that, actually, Dao An knows nothing about medicine. All she can do is tap her wooden fish drum and lead the entire team toward peaceful repose. Theme: Strive in your youth, and look forward to the future!
