Wang Ningyi ultimately chose to surrender.
No matter how stubborn, reality is harsher.
The Starport had been conquered by the Interstellar Warriors at almost all critical points. The Princess Legion soldiers had no way of reclaiming it; the firepower launched from the Starport destroyed the external Star Fortress and Armed Space Station.
The orbital defense system of the entire planet was virtually in ruins.
Once the main fleet of the Alliance cleared the orbital threats, the remaining ground cannon batteries would undoubtedly be unable to confront the main fleet of the Alliance.
If the Alliance were more ruthless, they could clear ground cannon battery fortresses corresponding to a sector of space, ensure no interception, and deploy Skyburn Torpedoes, achieving a one-time solution.
In his view, the war was already over. The subsequent battles were meaningless.
As Hussepe said, fewer casualties might be a good thing.
