Earth Martial Arts

Wu Bufan woke up and went back to eighteen years ago. Before he had time to rejoice that he had the opportunity to make up for the regrets of his previous life, he discovered that he had actually come to a different earth from his previous life. In 2000, the level of science and technology was probably even more advanced than in the previous life in 2018, but the fact is that even if the previous life develops to 2030, it cannot be compared with it. Why? Because humans on Earth in this world had established a lunar base 220 years ago, and in 1930 humans had footprints all over the seven planets in the solar system. Only because humans inadvertently opened Pandora's Box, Earth's technology has regressed by nearly 200 years.
