Start with a Dyson Sphere and I Can Conquer the Universe

Humanity is destroyed, and Lin Feng survives alone. One hundred thousand years of construction to create an industrial empire spanning the entire galaxy! Dyson spheres imprison stars, factory planets roar day and night, and billions of warships line up in the void. While other civilizations were still fighting for a planet, he had transformed the entire galaxy into a war machine. A swarm of insects is coming? Billions of ships swarmed in, converting biomass into industrial raw materials! Mechanical civilization provocation? The galaxy-level factory is operating at full capacity, crushing everything with a torrent of steel! Energy life changes? Detonate the supernova directly to see who has more firepower! The advent of high-dimensional races? Dimensional weapons are waiting to drag them down from the four-dimensional space with explosive hammers! With each civilization conquered, the empire grew stronger. Every time a star is destroyed, industrial capacity doubles. Battleships are like the sea, factories are like the clouds, and the entire universe is providing nourishment for this war machine. All racial harmony and cosmic balance must give way! In the face of absolute industrial strength, everything is a paper tiger! When Lin Feng's battleships cover the starry sky, when the Dyson sphere array lights up the Milky Way, and when countless civilizations tremble under the torrent of steel, the entire universe will witness what is called—— Humanity's mechanical storm! Absolute domination of industry! The supreme majesty of the Iron Empire! In this universe, either you die or I live. And Lin Feng chose to let all enemies die!
