Permanent Spacetime Fortress

At the same time, he activated the "Star Core Trans-Spacetime Fusion Cannon." A massive beam of energy struck the core, and it exploded with a deafening roar.

With the Quadrant Spacetime Core destroyed, the Quadrant Spacetime Mothership began to disintegrate. All the warships of the Hyper-Spacetime Legion lost the ability to travel between quadrants and descended into chaos. Chu Yunyi led the remaining defensive fleet in a full-scale assault. Bound by the spacetime rules of the known universe, the Hyper-Spacetime Legion's warships were no match for the defensive fleet's attacks. In the end, they were all destroyed.

Restoring Spacetime Order After the War and Embarking on a New Mission of Protection

After the Hyper-Spacetime Legion was wiped out, the spacetime order of the known universe gradually recovered. Chu Yunyi organized forces to fully repair the damaged Spacetime Crystal Wall Belt. At its weak points, they built Permanent Spacetime Fortresses and stationed elite fleets there for the long term. He also established the Cross-Quadrant Spacetime Research Center, bringing together scientists from civilizations across the universe to study the spacetime characteristics of unknown quadrants and the responsible use of Trans-Spacetime Energy, preparing for potential threats in the future.

Many years later, Chu Yunyi was still patrolling the universe aboard the Star Dome-V, now upgraded for the seventh time. The Cross-Quadrant Spacetime Defense Line had become the strongest barrier in the known universe, and the Spacetime Crystal Wall Belt had regained its former brilliance. Countless Spacetime Research Stations and observation platforms had been built there, where scientists explored the mysteries of spacetime and turned Spacetime Energy into a new force driving the progress of cosmic civilizations.

When Chu Yunyi returned to the Shattered Airspace, it had become the "Spacetime Recovery Demonstration Zone." The former Spacetime Turbulence Zone had been transformed into a "Spacetime
