After Time Travel, I Counterattacked on the Interstellar Technology Battlefield

When Tang Yu opened his eyes, the particle light screen was flashing a scarlet warning: the primary technological civilization will be expelled from the Interstellar Federation in three months. Without a system or superpower, how can he fight his way through the interstellar jungle where the jungle of the jungle is overwhelming? He cobbled together a wormhole jump device from an abandoned laboratory and resold the blueprints of his own Star Destroyer weapons on the arms black market. The technology madman, whose cold eyes were burning with wildfire, led Bo Yao, a genius mechanic who was exiled by his family, to tear apart the technology tree monopolized by the superpowers. When their antimatter engines roared to crush the arrogance of advanced civilizations, the entire galaxy was trembling - this technological storm caused by the lowest level will eventually rewrite the iron law of interstellar hegemony!
