Lu Li, an ordinary young man, unexpectedly received a mysterious express delivery. From then on, the gears of fate began to turn. A strange bracelet takes him across the vast universe and into the vortex of interstellar disputes. He was first hunted by alien creatures, and then fell into a fierce battle between interstellar pirates and the interstellar alliance, witnessing the glory and destruction of the Nebula Smart Factory.
Lu Li, who was lucky enough to escape and return to Earth, started in-depth cooperation with the Dragon Kingdom by relying on the technology left in the bracelet fragments. They started by developing "miniature energy-gathering cores", climbed the technology tree step by step, made up for various technological deficiencies, and led the Dragon Kingdom to break out of the earth and face the civilization of the universe.
