My Great-Grandson Who Was Accidentally Possessed by Me Is the Savior

In the 24th century, the unknown organic life form "Black Beast" descended on the earth. They carry a special force field: a unidirectional force. All forces exerted by humans are unilaterally repulsed, and the laws of physics lose their meaning before them. In desperation, Dr. But the good news from the front did not stop him. He forcibly pushed forward the quantum transformation of the city at an almost paranoid speed. On December 11, 2324, Dunhuang, the first autonomous migration city built by quantum nanomachines, was completed. On the same day, the first giant black beast "Reappearance of Disaster" appeared, easily tearing apart mankind's last line of defense. In despair, Dunhuang turned into a giant that covered the sky and the sun, tearing it into pieces with his bare hands. From then on, human beings took autonomous migration to cities as their territory, and eleven cities formed the Spartan Alliance. The backbone of the alliance is the Combat Skills Training Group, the highest combat force in mankind that can drive the city to transform into giants and kill giant black beasts. On October 20, 2334, the fourth seat of the teaching team, Colonel Han Lei, codenamed "Hypocritical Executioner", was attacked by a logic virus of unknown origin while facing an unknown giant black beast in Venice, the 332nd self-discipline migration city, and his brain was severely injured. After emergency genetic memory reconstruction surgery, his grandfather's grandfather, the 21st century theorist Han Feng, woke up in this perfect body. Humanity's counterattack begins from this moment.
