Dressed as a concubine who was not favored by the generals, Dai Qingling was forced to disguise herself as a man and join the army in her brother's place in order to survive. Bad news: She has no strength, she is incompetent in writing and military, and she is just cannon fodder in battle. The good news: She has a good brain and is especially good at observing details and logical reasoning. In order not to be thrown out as cannon fodder, Dai Qingling had an idea and set up a semi-immortal character for himself who "knows the secrets of heaven and predicts misfortunes and blessings". From then on, there was a peculiar scenery in the military camp. "General, there is too much murderous intent in the southwest today, and the dust is rising without wind. It is not suitable to send troops." The next day, the spies reported that three thousand elite enemy troops had been lying in wait at the entrance of the southwest valley for a whole day. "Commander, there is something wrong with this batch of grain and grass. The soles of the grain transport soldiers are stained with the red soil that is only found in the east of the city." Sure enough, there was croton in the grain and grass, which made the entire battalion's legs weak. "When digging a well, dig into that depression, the grass there will be greener." - Successfully solved the water shortage crisis for the entire army. Dai Qingling's reputation as "divine fortune teller" spreads more and more widely, and he is about to be praised as a living god. Only Xie Wuyi, the newly appointed cold-faced governor, who was the king of hell on the battlefield and who disbelieved in ghosts and gods the most, stared at her with a pair of eagle eyes, determined to expose her "deception". Xie Wuyi blocked her in the handsome tent, with sharp eyes: "If you are really capable, what color will my underwear be tomorrow?" Dai Qingling said expressionlessly: "General, to show innocence, it's best not to wear anything tomorrow." !
