From Between the Gaps

Ten billion years ago, several universes collided head-on. That great collision annihilated all life in the old era and gave birth to a whole new world. Spiritual energy, magic power, divine water, and underworld currents—these powers that should have been mutually exclusive were now flowing under the same sky at the same time. The flying swords of the cultivators and the portals of the magicians passed by in the same dusk, and the chants of the temples and the blasts of the superpowers overlapped on the same battlefield. This is the worst of times. Yechen was born a useless person - with mixed spiritual roots, useless magic circuits, zero divine followers, and no superpowers. He was destined to be eliminated in this multi-system world. This is also the best of times. Because what is left behind by the big collision is not only chaos - but also the complete technology trees of the dead universes, quietly sinking in the void waiting to be discovered. When the immortal cultivators were still fighting for a book of skills, when the magicians were still losing everything for a magic core, when the gods were still praying for mercy from the gods, Ye Chen had already opened the blueprint for assembly line production. A useless man, a steel city sleeping in the void, a fire born from the ruins. This time, he wants to use the legacy of the dead civilization to bring about a complete revolution in this barbaric world.
