The situation on Blue Star is just like the mathematical problem involving a pool; once the speed of the water leaving the drain is faster than the water entering, then the Plane invaded last time by Dong Tianyu, namely the future of the Blue Star Plane.
Even though Dong Tianyu possesses the ability of Sword Flight, when facing Otherworldly Invaders that could appear anytime and anywhere, regardless of Dong Tianyu's strength, relying solely on him proves futile.
However, for someone like Dong Tianyu with immense individual strength, instead of staying on Blue Star to defend, the best course of action is to serve as the Vanguard Army, entering other Planes through the Plane Transmission Channel to acquire the Plane's origin, which is more cost-effective.
Just as Dong Tianyu was pondering this issue in his mind, he suddenly felt an itch on the skin exposed to the outside world.
