Travel through time and become a down-and-out aristocratic young man in the interstellar era. The territory was poor, resources were scarce, the starship was dilapidated, and a mess was thrown in front of Zhao Chen. There is no stargate in the territory? Let's make it ourselves! There are no starships in the territory? We build star destroyers, star frigates, and star cruisers whatever we want. The empire developed a starship with T5 technology? Sorry, I have already served a fleet of T5 starships!
It's a good shot, much better than the novel.
