I caught up with the trend of time travel and rebirth. I originally thought that I would be as domineering as the protagonist in the novel, and he would be able to dominate the world and rule the world forever, form a harem of beauties, and collect beauties from all over the world. However, the first problem in time travel was the language barrier. I also discovered that there was already a time travel predecessor in this time and space, and the things left by the predecessor can be called artifacts. But why is there no record of this predecessor in history? Will I also disappear under the wheel of history? Am I a bystander of history, a participant in history, or even a creator?
