I, the Richest Man in the Tang Dynasty, Have Been Exposed by My Sister!

Lin Xuan, who traveled through the Tang Dynasty with his system, wanted to quietly become a rich man forever and get along with the people of the Tang Dynasty as an ordinary person. But one day, two old men suddenly came to the door. After eating a plate of stir-fried potato shreds, the secret of being the richest man in the Tang Dynasty was exposed by his sister! Li Er: "What did you say? This thing can produce three thousand catties per mu?!" Sister: "My brother said, doesn't it just have to be done with hands?" Li Er: "This fine Japonica rice, your family uses it to feed the dogs?" Sister: "My brother said that dogs won't even eat this stuff!" Changsun Wuji silently put down the bowls and chopsticks in his hands: "Are you polite?" … Until one day, Li Er finally got to see Lin Xuan's true appearance, and suddenly discovered that this damn son was actually his eldest son who had disappeared many years ago! Li Er: "Son, go back to the palace with your father, and let you sit on the splendid land of the Tang Dynasty!" Lin Xuan waved his hand without interest: "With my invincible fleet, what else do you need for bicycles?" "Today I am happy, I will knock down Europa first!" "What is the military expenditure? Enough!"
