Reborn as the Chief of the Human Alliance

That day, the sun disappeared. The overwhelming fleet descended into Earth's orbit - each one larger than the moon - and they blocked the sun - turning the entire sky into pure black. Then, a white light. Ye Hui closed his eyes. When he opened it again, he was back to the age of twenty-five - the first day of registration as a graduate student - and there were five more things of unknown origin in his mind. Ye Hui in his previous life was thirty years old. A failed researcher. The thesis was stuck in the seventh step for two years. I was forced to change the topic in order to graduate, and I graduated mediocrely. His mother died of illness when he was twenty-eight, and he failed to save her. He worked as a research assistant in a small laboratory and was completely defeated by life. Then he saw the fleet. Saw the white light. Then he went back to five years ago. In this life, he has two goals: First, save my mother. Second, get back everything you lost in your previous life. Eighty-seven million people choose to stay on Earth - to resist alien civilization - and to use their lives to protect a planet that is about to be devoured. Before they died, they shouted in unison: "The glory of mankind endures forever!"
