Back to 2005, Using Technology to Change the Future

I still remember the feeling of powerlessness when the giant ship hundreds of kilometers long docked above the blue star when the end of the world came. At the last moment, various countries activate time travelers to reverse time and space. Trying to use time travelers to travel through the past to improve Blue Star technology to bring them closer to the technological level of foreign languages ​​​​to protect themselves. After experiencing nine times of traveling and being blocked and killed by foreign civilizations, only Lin Fan, the last traveler from the Dragon Kingdom, was left. Lin Fan gathered all his energy and returned to 2005 for the last time. It is not that this time point will definitely save Blue Star. But Lin Fan wanted to go back to this point in time that made him regret his whole life, to save his Bai Yueguang. Using the knowledge brought by the system to improve Blue Star's technological level. This time, it is not for Blue Star, but for Bai Yueguang, who just wants to protect himself. Even if he sacrifices himself, he must build a starry sky empire to resist foreign civilizations. This novel and its characters are purely fictitious.
