I Got Cash Back After Losing Huff Coins, and I Became the Richest Man After a Fierce Attack.

Lin Dong became a freshman at Shanghai University of Finance and Economics after traveling through time. When driving Black Delta with my roommates, I accidentally discovered that the Huff coins I lost can be returned to cash! If you lose 1 million Huff coins, the system will return 1,000 yuan! However, it only costs 6 yuan to earn 10 million Huff coins through agent running! "High-end wealth often adopts the simplest way of making money——" "Attack!!!" Ever since, Lin Dong directly used the prehistoric gun with magic bombs and splashing water, prepared six full sets of cards for combat, transformed into a humanoid Said, and moved across the aerospace central control bridge! When professional players come, they have to eat 125 red eggs before they leave! He is the god of players, the bread and butter of knife-running players, the nightmare of attacking players, and the mountain that is difficult for professional players to climb! Just when the world thought he was an e-sports prodigal, little did they know that Lin Dong's property had already spread across various industries such as medical care, catering, automobiles, movies, etc., And he had unknowingly become the richest man in the world...
