"The Years when the Lord of the Universe Became a Grandson on Earth" is a wonderful novel that combines interstellar civilization, counterattack by a vest, and a high-energy slap in the face.
"Yu", the master of advanced civilization, was seriously injured in the space war and fell into the slums of the earth. As soon as he landed, he was treated as a homeless man by the villain Lu Xiao. He was humiliated, his right eye was gouged out, and he was also reduced to a "human punching bag" in the underground boxing ring. Fortunately, he was rescued by Lin Wan, a scavenger girl. Lin Wan's father was silenced by the Lu family for discovering the "Inscription on the Earth's Core Civilization", and the pendant in her hand turned out to be the key to Yu's flagship.
Suppressed by the earth's magnetic field, Yu's power was weak, but he began to fight back with his remaining precognitive ability. He used this ability to win tens of billions from Lu Xiao in the casino, making him embarrassed in public. Later, he mixed into the antique black market to repair the "Gravity Ring" and punished the Lu family's minions as a "Night Dire".
As the plot progresses, the Lu family's conspiracy gradually comes to light. They awaken the geocentric mecha "Pangu" and attempt to use Yu's heart to initiate the annihilation process. Yu and Lin Wan are wanted globally, and their relationship heats up in life-and-death crises. Lin Wan is shot and dying to protect Yu, but Yu uses interstellar radiation to save her, and his right eye is completely mechanized.
In the final battle, Yu fought with the "Pangu Mecha" on the wreckage of Mars and used Lu Xiao's neural link to reversely invade the control system. He rejected the rescue fleet from his home star, used the earth as a chessboard to lay a "black hole trap", and completely annihilated the Annihilation tribe. After the war, Yu San used up all his magical power to become a mortal, but he was greeted by the universal language of the universe made up of lights around the world, "Welcome my God to return to his throne." The fire pendant in Lin Wan's arms lit up, and new cracks in the universe were expanding, leaving the story with wonderful suspense.
