Federation Year 91.
The remnants of the Vera Alliance forces that had retreated from the defense line in the direction of the Galactic Core Channel's Fourth Major Spiral Arm arrived at the Satchers Defense Line under the cover of the defenders, bringing 50 billion warships with them.
This caused the number of defenders at the Satchers Defense Line to swell from 100 billion to 150 billion in an instant.
Of course, this numerical advantage did not last long. The Freedom Alliance army, with its 100 billion warships in hot pursuit, also arrived near the Satchers Defense Line and joined up with the Zola Alliance, bringing their forces to a staggering 190 billion warships.
Neither alliance was surprised by the Vera Alliance fleet's withdrawal from the Galactic Core defense line. After all, with only 50 billion warships left, standing against the Freedom Alliance's 100 billion warships would have ended badly. They might as well retreat to the Satchers Defense Line and make one final stand!
Before long, a massive battle involving as many as 340 billion warships began.
The Freedom and Zola Alliances launched fierce assaults on the Satchers Defense Line from multiple positions at once. Naturally, the defenders on the Satchers Defense Line immediately struck back, and the two sides traded blows in an exceptionally fierce battle.
After all, even a difference of 40 billion warships would not show its effects right away. At most, it meant that the Vera Alliance's reserves would be far weaker than those of the Freedom and Zola Alliances.
Yet as the two alliances launched their fierce assault on the Satchers Defense Line, they failed to realize that the Xio Alliance army—a full fleet of 100 billion warships—was behind them at that very moment, ready to take a bite out of them at any time.
