Kaguya and Katsuyu's Personal Warships

When the Otsutsuki Civilization went to war with its greatest competitor, both sides had used common celestial bodies like stars as bombs during the decisive phase, hurling them between star systems to destroy the systems controlled by the other side.

The traces of that war remained to this day. The densely layered nebulae spanning hundreds of galaxies, whose formation dates differed by less than twenty thousand years, were the remnants of stars destroyed in great numbers back then.

That was universe-scale map-editing power. If the Zenith Civilization could master such power, it would not merely become invincible in this universe—even in the Interstellar Universe, it could stand alongside the three major races, instantly turning the situation into a struggle among four major races.

So-called Planetary rank meant using planets as weapons. The two great beauties had clearly been overthinking things.

In order to achieve self-propulsion for the three Planet Fortresses built by the Zenith Civilization, countless plans had been tested. In the end, they built Virtual Black Hole engines that achieved propulsion by distorting space.

The scale of a planet's black hole engine far exceeded expectations.

Virtual Black Holes could not be placed too close together, or serious accidents involving mutual mergers would occur. Yet if they were too far apart, it was difficult to pack in enough black holes.

Thus, the Advents arranged several hundred Virtual Black Holes tightly together, forming a massive ring array thousands of kilometers in diameter. This was one basic unit of the black hole engine.

There were ninety-six such giant basic units, arranged at varying angles and distances to form the enormous black hole engine.

Once activated, this engine consumed over a hundred tons of matter every second, usually hydrogen, the easiest element to collect.

After swallowing vast quantities of matter, the Virtual Black
