From Slave to Human Emperor, Then Slaughtering My Way Through Another World for Humanity

His name is Lu Nian. After a nuclear explosion sent him to another world, he rose from the lowest depths of society, a beggar, fought his way through rivers of blood, and became the Duke Who Guards the Nation of the Great Han Dynasty. But when his beloved died and the realm stretching thousands of miles turned to ashes, he abandoned everything and traveled alone through the snowy north, the western deserts, Jin, Great Chu, and Great Wei. In the depths of despair, his fighting spirit burned anew. With the sixteen western kingdoms marching on the border and the Central Continent hanging by a thread, he was entrusted with command of its allied forces. In a single battle, he turned the tide and crushed the cavalry of all sixteen kingdoms, including Ares, Lostania, Northend, the Silver City-State, and the Lionheart Kingdom. But he did not stop there. He led his forces west, crossing the Japanese Isles, East India, Great Yue, and the Egyptian Dynasty, and matching wits with Emperor Caesar, Emperor Pompey, and Cleopatra, Queen of Egypt, amid tangled love and hatred. Athens, Greece, and Rome were reduced to ruins beneath his feet. He uncovered the secret of the Great Pyramid of Khufu, and the Golden City of the Inca Empire and the legendary City in the Sky both submitted to his advance. Yet the true battlefield was far from over. At the Great Wall of the Northern Crown of Hercules, humanity's armies faced the Celestial legions, and blood stained the river of stars. In the Boundless Sea, he encountered sunken Atlantis, fell in love with a mermaid princess, and found a slender hope of survival in the depths. At last, a tide of monsters from another dimension swept across the skies above the Southern Sea Great Wall. With the survival of every race hanging by a thread, he stood in the firmament, the last hope of humanity at his back. This time, he would fight a path to the future for the entire Central Continent, and for every living being.
