Arc 21Humanity in the Mirror Sub-Universe
Hu Yu’s deception drew Li Shun and the Fish Horse Star Civilization into a devastating war that shattered humanity’s forces and cost the Tree Race its home. Trapped in the Mirror Sub-Universe, the survivors rebuilt their technology until Zu appeared, took half the Conquerors as hostages, and demanded the destruction of fifty supermassive black holes.
- Hu Yu staged his death to lure Li Shun into revealing his forces, then led the Conquerors and Bi Cha’s fleet against the mechanical insect swarm and Fish Horse Star Civilization.
- Hu Yu used two-dimensional Conquerors to plant bombs in Fish Horse Star warships and mechanical insects, destroying the forces on one battlefield before the Fish Horse fleet attacked the Solar System.
- Hu Yu’s fleet and the Tree Race tried to flee through the Mirror Sub-Universe exit, but the Fish Horse Star blockade trapped them in a spatial millstone.
- Hu Yu and Bi Cha opened a path through the millstone at enormous cost, and the Tree Race patriarch sacrificed himself so the survivors could escape into spatial fragments.
- Hu Yu’s surviving fleet sheltered in the Mirror Sub-Universe, where Academician Liu discovered Three-Dimensional Basic Space and the academicians began developing new energy over thousands of years.
- Hu Yu found that only sixty billion ships remained before Zu transported the fleet to a stable space and demanded the destruction of fifty supermassive black holes in exchange for abundant energy.
- Zu took half the Conquerors as guests until Hu Yu fulfilled the demand, while the remaining humans rebuilt their equipment and developed a way to synthesize Two-Dimensional Energy.
