Play Games with Ancient People and Train Time Travelers

The system is tool man + parallel time and space + other novels This novel mainly focuses on historical figures in the early stage, and then begins to travel through the novel. Make those protagonists strong so they can walk around the universe. I want to confirm here that the person who really wants to write should be me. After all, I have a lot of thoughts that I want to write. The protagonist is named Guo Han, but his other real name is Yi Jinhan. These other things are all my own thoughts, so if you read them, you will basically see them all from my own thoughts. Others are from history or novels, but they will also be set up by me in competitions during time travel, so stay tuned.
