The Overlord of the Universe's Years as a Grandson on Earth is an exciting novel combining interstellar civilizations, secret identities, and high-octane face-slapping.
Yu, ruler of a highly advanced civilization, is gravely wounded in a cosmic war and crashes into a slum on Earth. The moment he lands, the villain Lu Xiao mistakes him for a vagrant and humiliates him, gouges out his right eye, and turns him into a human punching bag in an underground fight club. Fortunately, scavenger girl Lin Wan saves him. Her father was silenced by the Lu family for discovering an inscription from Earth's core civilization, and the pendant in her possession turns out to be the key to Yu's flagship.
Suppressed by Earth's magnetic field, Yu's power is weak, but he begins to strike back using the precognitive ability he has left. He uses it to win ten billion from Lu Xiao at a casino and humiliate him in front of everyone. Later, he infiltrates an antique black market to repair the “Gravity Ring” and punishes the Lu family's henchmen under the identity “Nightmare.”
As the story unfolds, the Lu family's schemes gradually come to light. They awaken the underground mecha “Pangu,” hoping to use Yu's heart to activate an apocalyptic program. Yu and Lin Wan are wanted worldwide. Their feelings deepen through repeated brushes with death, and when Lin Wan is shot while protecting Yu and lies near death, Yu saves her with interstellar radiation, leaving his right eye completely mechanized.
In the final battle, Yu fights the “Pangu Mecha” atop the ruins on Mars, using Lu Xiao's neural link to hack into its control system. He refuses rescue from his home planet's fleet and lays a “black hole trap” across Earth, wiping out the Darkening Clan. After the war, Yu relinquishes all his divine power and becomes mortal. Yet he is greeted by lights across the globe spelling out the universal language: “Welcome home, our God.” The seed-of-fire pendant in Lin Wan's arms begins to glow, and a new rift in the universe is expanding, leaving the story on a thrilling cliffhanger.
