Traveling Across the Heavens, Just to Rewrite Regrets

My name is Teng Fan, I was born on February 15, 1997 under the zodiac sign of Aquarius, born in the year of Ox. I am an ordinary man with a monthly salary of 9K, a house and no mortgage, who considers himself selfish, lustful and afraid of death. Passed away suddenly on August 15, 2026, at the age of twenty-nine. My only superpower is believing that I am going to die every day before I go to bed, and then being crazy scared. Afraid that the regrets in Chinese history cannot be repaired, afraid that Zhao Yun's gun failed to pierce the long night, afraid that the wind in Jingkang was too cold, and afraid that the princesses who died young have not seen the flowers of spring. The moment I hit the keyboard and wrote myself as a sacrifice into the novel, the accident came true. I'm dead, but not quite dead. A thing that calls itself "the shuttle system of all heavens and realms" bound me. It said that I was a lucky person randomly selected by the "highest dimension universe". It also said that this universe would be "swallowed" and asked me to take the system to invade other planes. I refused. [The host refuses the invasion mission. Current mode: Regret Crystal Collection/Plane Depth Influence. "I'm not going anywhere," I (who should now be called "her") said, "First stop, I'm going to the Time Lord universe and steal the Blue Pavilion." The system collapsed: "That's... That's a god-level plane! And you just reincarnated into a little girl!" "You don't understand. Before time travel, I was a loser who could imagine all the worlds in a one-square-meter workstation." "Now - I just want to confirm whether the Time Lord in the blue box can take me back to Xijing in 2026 AD and find the other me who hasn't started writing novels yet."
