I Am the Great Sage

This is a world teeming with countless humanoid races. The smoke of the ten-thousand-year war between Daoism and the demonic path has yet to clear, and old grudges from five thousand years of conflict between humanity and the demon race remain unresolved. The Great Xia Kingdom, the Heavenly Spirit Sect, the Demonic Cult, the imperial court, the Witch Clan, and the demon race divide the land and keep one another in check. Beneath the roiling undercurrents, war could erupt at any moment. Sun Lei, an overworked corporate drone, unexpectedly transmigrates to this world. After merging with the Great Sage's legacy, he awakens formidable physical strength. Applying modern team-management and military-deployment strategies, he efficiently makes the most of scarce resources and builds a distinctive combat force. He turns his territory into an impregnable frontier fortress on the northwestern border of the Great Xia Kingdom. Combining modern military technology with the world's spiritual energy and Daoist arts, he uses modern ingenuity to revolutionize the battlefield. Fighting shoulder to shoulder with his comrades at the head of an ironclad army, he rises against the odds amid the fires of a chaotic age, composing an otherworldly legend that defies fate as he gradually uncovers the ultimate truth behind ten thousand years of conflict.
