At the Beginning of the Collapse of the Sky, the Skills Blogger Made a Fortune Through Time Travel

Su Ling, a skills blogger, was suddenly involved in a car accident and traveled to a dynasty that was not recorded in history books. He also brought with him an exchange system panel. As soon as Su Ling came across, his sister was sold. Grandma favored Dafang and exchanged money for Dafang to study. The family was poor, but fortunately the mother of the original owner saved some money and used modern knowledge to make a fortune! ! ! ! I don't know how to write an introduction, please forgive me.
