It's a Showdown, I Am the Number One Salted Fish in the Tang Dynasty

[History + time travel + lighthearted comedy + anti-routine + system] Su Chen traveled through the Zhenguan era and was bound to the "Strongest Fishing System". Just fish, paddle, and avoid responsibilities, and you'll be rewarded. The more salty you are, the more generous the rewards will be! At the beginning of the court meeting, Su Chen hid in the corner and fell asleep. Bite! It was detected that the host was sleeping openly in the court, and the rating of the fish-fishing behavior was: unprecedented! Reward: High-yielding sacred rice "Champa Rice"! Proficient in "Essential Art of Elevating the People"! Li Shimin: "You traitor! As a court official, how dare you sleep soundly in the court hall! Someone, drag me out!" Before he finished speaking, the military report from the Turkic invaders was rushed 800 miles away. The civil and military forces of the Manchu Dynasty were helpless, and Li Shimin was in dire straits. The sleepy Su Chen was woken up and muttered casually: "Why fight? Winter is coming. A heavy snowfall will freeze them to death. Can't we just send some people to the edge of the Wei River to sing about the empty city strategy?" Li Shimin: "???" From then on, a freak appeared in the officialdom of the Tang Dynasty. The more you try to demote him, the more auspiciousness he "unintentionally" offers. The more you want him to work, the more new crops he fishes out will fill Datang's belly. Fang Xuanling: "Your Majesty, although Su Chen is lazy, he is an important weapon of the country!" Changsun Wuji: "This son has always made unparalleled contributions to our Tang Dynasty invisibly. Could it be that he is an immortal?" Li Shimin: "Su Chen! I will make you the Duke of the country. Get up and work for me!" Su Chen: "Your Majesty, please, let me be a waste, I just want to fish!"
