After My Rebirth, I Took My Senior Sister to Explore the Stock Market!

One second, there was still a financial giant with 2 billion, and the next second, the rooftop jumped. Open your eyes again? He was reborn and returned to college with only five hundred yuan in his pocket! The former stock market tycoon now wants to stick to his senior sister to save his principal again? The K-line trader now has to calculate the 50 cent price difference... Senior sister, where is the aloofness you promised? Why are you more excited than me to keep accounts and shout? Okay, since fate has allowed me to climb back up from the bottom, I will use this most "down-to-earth" way to build up the lost empire again with the interest and in the most unexpected way - with my own hands!
