This is a solution, but Finn Lewis was reluctant to do so because if they were to go alone, it would be easy to encounter some problems. If the star charts and the like were correct, then, after their successful arrival, should any other issues arise, Finn and his team could offer assistance.
Moreover, the time needed to travel to the galactic center wasn't short. For the first trip, whether the star maps were accurate was unknown, so some areas had to be flown over. Even with flying, the tremendous distances involved would require at least a year of travel time.
There, would you dare to travel faster than light? Definitely not. In the situation where gravity fields are undetected, being able to travel at one-third the speed of light would already be considered fast.
"No, if you encounter any dangers, having us to help would mean you could escape. At least for now, we can't afford to lose any allies," Finn said with a serious tone.
