Hu Yu’s fleet rebuilt its strength at Tau Ceti, developed faster-than-light travel, and defeated the predatory Sand Python Civilization at enormous cost. As the fleet prepared to expand toward Alpha Centauri, the Sand Pythons accepted a secret offer from the Patrol to destroy humanity, while Hu Yu’s scientists began confirming the existence of the fourth dimension.
Hu Yu’s fleet escaped a pursuing civilization by hiding in a four-dimensional bubble, destroyed the Sand Python fleet, and found an ancient Snow Tribe willing to share knowledge. The fleet then encountered a giant insect swarm and tested its biological warriors, which devastated the insects from within.
Hu Yu infiltrated the Wind Star Civilization, expanded humanity’s worlds and fleet, and gained help from the Treefolk prince Ninety-Seven. As Wind Star prepared for revenge, Hu Yu shifted from long-term covert plans to an imminent attack.
Hu Yu led humanity through the defeat of Wind Star and the Fish Horse Star People’s pursuit, while Ninety-Seven sacrificed himself to carry Earth Two into the Pillars of Creation. Decades of rebuilding restored a large fleet, but its trial ships then suffered an unexplained loss of speed.
Hu Yu’s fleet confronted the conscious nebula lifeforms, survived their assault on Earth Two, and agreed to help them become biological beings under a 200-year deadline. Humanity then began studying the nebula and building a secret defense, while Academician Liu Bo returned with a breakthrough about spatial density.
Hu Yu led humanity from the nebula region, built new weapons and technology, and launched a rescue mission for Luo Zhigao’s fleet trapped by the Xuan Star Civilization. After sacrificing the Wind Master fleet to hold off the enemy, Hu Yu reunited with Luo Zhigao at Earth Two, where the two fleets began rebuilding together.
Hu Yu’s fleet spent centuries preparing to confront the Xuan Star Civilization, but its overwhelming forces and the failure to move a spatial vortex forced Hu Yu to rethink the campaign. After returning home and reconnecting with Xiao Xiao, Hu Yu adopted Hu Yunhang’s idea of tricking the enemy into carrying the energy spheres themselves, leaving the fleet to develop the Trojan Horse Plan.
Humanity used Reversed State armor and a Trojan Horse Plan to draw the Xuan Star Civilization into a devastating war, then forced its leader to offer a secret about the Insect Race. The Fish Horse Star Civilization interrupted the revelation, and humanity’s attack on Mu Star territory showed Hu Yu how powerful the Fish Horse Star Civilization was.
Hu Yu’s fleet encountered another human branch, survived Li Shun’s attempt to seize it, and later formed an alliance with six civilizations while settling in JD6. The search for Zhang Yuanshan and Ninety-Seven continued as humanity developed new spatial weapons and prepared to probe suspected locations of the Treant Civilization.
Hu Yu formed an alliance with the Tree Race and led a massive operation to free its captives from the Far Watcher Civilization. The rescue succeeded, but the Heavenly Peak Civilization intervened afterward, and Hu Yu sought answers from Daozi.
Hu Yu and the alliance prepared to free the Xuan Star Civilization from Fish Horse Star control while studying the Insect Race and developing a way to assassinate Xuan Star’s leader. After humanity’s stellar explosions disrupted Xuan Star’s territory and an insect swarm trapped its evacuation fleet, the alliance sent Reapers and Stingers to help.
Hu Yu’s alliance defeated the Fish Horse Star Civilization, welcomed the Carina Civilization, and prepared an expedition through insect territory to reach the Matter River. While the expedition advanced, Hu Yu’s forces contained a swarm threatening the Eastern Pearl Civilization, then the fleet encountered a sudden emptiness in the insect zone.
The Reapers crossed the Matter River, survived its danger zone, and built a powerful alliance over thousands of years. Hu Yu later found the unconscious Xuan Star people and their Wind Star attackers, then watched the Xuan Star leader begin a brutal interrogation.
Hu Yu’s alliance faced the Mechanical Civilization and used the insect swarms and fourth-dimensional attacks to defeat its assault, while researchers uncovered a dangerous sub-universe in the Matter River. The arc left Chen Peng, Li Zhixiong, and the academicians stranded deep inside that region as they investigated its strange laws and searched for a way back.
Hu Yu led the Star Ring Alliance through an invasion while Luo Zhigao’s fleet endured a deadly detour into a black hole and a separate timeline. After rejoining the normal timeline, Luo Zhigao reunited with Hu Yu, and they agreed to share technology and face their enemies together.
The academicians returned from the Matter River without Liu Bo and Chen Peng, but brought back Fourth Reversed State research as the Star Ring Alliance faced the Mechanical Civilization’s expanding insect swarms. Hu Yu’s alliance rallied civilizations across the galaxy and won major battles, but the insect king’s four-dimensional attacks left the war unresolved.
Hu Yu prepared the Reapers to enter insect territory and rescue Academician Liu, while Wen Zhonghua’s fleet fought Li Shun and the swarms before encountering the Mechanical Civilization. The surviving Reapers escaped into the Matter River and reunited with Academician Liu Bo, Chen Peng, and their companions.
Wen Zhonghua’s fleet escaped the Matter River and returned to the Alliance, while Hu Yu prepared humanity and its allies to attack the Fish Horse Star Civilization. The assault exposed the Wind Star Civilization’s involvement and ended with the Reapers trapped inside compressed space near the enemy base.
Hu Yu led the Star Ring Alliance through victory over the Fish Horse and Wind Star civilizations, the restoration of the Solar System, and a long campaign to strengthen its fleets and developing civilizations. The arc ended with five hundred billion Conquerors waiting in the fourth dimension to confront the elusive Mechanical Civilization.
Hu Yu led the alliance against the insect swarm and used Neutron Star Cannons to shatter its main forces, while Li Shun secretly seized control of the Insect King. Humanity entered the Galactic Alliance’s core and learned of the threat from Andromeda, before Zhou Xiaohua solved the problem of locating the three-dimensional universe from the fourth dimension.
