On his eighteenth birthday, Lynch stood in front of the light door. Behind the door is the investment world - every adult has to experience it for thirty days, and those who have a return rate of less than 10% will never come back. There is no "Three Body", no "Dune", and no "Galaxy Empire" in this world. There are three thousand investment world backgrounds, an unknown civilization that is completely unfamiliar to everyone. Except Lynch. Because he traveled from another world, bringing with him all the science fiction memories of the 21st century. When the system prompted "You have entered the Trisolaran civilization's home planet", he smiled. Wall-facing plan, ladder plan, guzheng plan... Long-term concept stocks in the eyes of others are a sure-win gamble that he already knows the outcome. Thirty days later, Lynch walked out of the business with a profit rate of 100,000%. What unfolded before him was an endless territory of three thousand investment worlds. In every world, there may be a story he has read in his previous life. Every time you place a bet, you gain huge profits in exchange for knowledge. Investment is risky, so be cautious when entering the market. Lynch's bargaining chip is the memory of his entire past life.
