Su Qingyuan has been unlucky for twenty-two years. He lost his father when he was young, and after his mother remarried, he suffered domestic violence from his stepfather for many years, and was bullied by his selfish and arrogant half-brother. When he was a student, he was isolated and bullied by his classmates, and his true love was also cheated on by his girlfriend. After a rough life, he thought he would be stuck at the bottom of the mud forever. A turning point came when he inherited the old-fashioned small supermarket left by his grandmother. This inconspicuous shop hid a secret. It could actually connect to another ancient world, allowing him to meet Xiao Linfan, the third prince of Dayao who was in trouble. When they first met, Xiao Linfan was surrounded by assassins. His sword was broken, he was defenseless, and he was in a desperate situation. At the critical moment, Su Qingyuan took out a modern precision watermelon knife. The blade was sharp and cut iron like mud, far superior to ancient weapons. Xiao Linfan immediately bought it with a rare ruby. Su Qingyuan sold it and received 250,000 yuan, completely getting rid of poverty. Later, Xiao Linfan came to ask for help many times. There was a severe drought in Xingzhou and the people were starving. Su Qingyuan provided a large amount of rice, flour, grain, oil, melons, fruits and water, which solved the desperate situation. In exchange for a pile of gold bricks, he made a net profit of five million and achieved financial freedom. The battle was fierce in the bitter cold in the north. The soldiers were suffering from cold and fatigue and lacked armaments. Su Qingyuan also sent a full set of warm clothes, compressed biscuits, instant noodles and other convenient materials to help the border troops tide over the difficulties. Xiao Linfan gave him top-quality Hetian jade, which made him earn tens of millions. With material assistance time after time, Su Qingyuan helped Xiao Linfan resolve natural disasters and wars, and quell crises between the government and the opposition. In the end, Xiao Linfan cleared up the civil strife, took control of the world, and successfully ascended the throne as emperor. He sincerely expressed his gratitude, "Thank you, Brother Qingyuan, for helping me reach the top of the 9th Five-Year Plan." Su Qingyuan's eyebrows were brisk, he turned against the wind, his half-life bad luck was gone, and he suddenly became rich without worries.
