Become the Richest Man Through Time Travel

After being left alone on Mars, Lu Guansheng learned that his younger brother had joined forces with a competitor! There is no food, no water, and soon, the oxygen will be used up. When he ran out of ammunition and food, he was disheartened and regretful. When he felt that death was coming, Lu Guansheng secretly swore that if he had known that he would end like this now, he would not have softened his heart three years ago. When he fell, the bracelet's golden light flashed, and a space-time door opened. Lu Guansheng fell directly into the time and space door that suddenly appeared. When he woke up again, the two bodies that existed in different time and space reunited, and he really went back to three years ago! Since God is merciful and gives him a chance to start over, then this time, he will never be soft to people who are not worthy of it! From then on, Lu Guansheng went further and further in the chain of revenge, adventure and everlasting career... PS: Thank you to my number one fan Mu Feng and old bookworm Le Zheng Huan Feng! I also hope there will be more support from old bookworms!
