"When a scholar meets a soldier, there is no explanation." This statement was clearly confirmed when Su Ran met Xiao Yi.
On the way to take the exam, Su Ran was running out of money, so he set up a letter-writing stall in the town. Instead of waiting for a big business, he waited for Xiao Qianhu with a knife. Just because of a false alarm from his subordinate, the iron-blooded general who had just wiped out the bandits regarded him as a "black-hearted man who swallowed silver coins." After the misunderstanding was solved, the weak scholar bravely "rubbed" the general's team, and along the way, they went from misunderstanding to mutual understanding: Xiao Yi captured bandits and marched in a hurry, Su Ran and Diu mistakenly broke into the real bandit's lair, but with their cooking skills and experience in poisonous weeds, they poisoned twenty or thirty bandits to paralysis, leaving the general stunned.
They were originally happy enemies, but they gradually became entangled in the undercurrent of the court of "valuing civility over military affairs" and the crisis of the Japanese country's surveillance. But when the Japanese envoy held up a model of the English cannon to provoke, Xiao Yi led his troops to the expedition but was defeated and disappeared. Su Ran clutched the old letters in the general's ancestral home and became red-eyed - how could this weak scholar break the situation with his pen and ink? Will the general who disappeared at sea return? This "unexplainable" fate will eventually be determined together with the fate of the family and the country.
