In the twenty-fourth year of Jian'an, after Liu Bei falls from his horse and loses consciousness following a great victory in Hanzhong, he awakens with the soul of a military-industrial commander from a later age. Though nearing sixty, his body is as vigorous as a young man's. He reorganizes the army, upgrades its weapons, improves the repeating crossbow, the wooden ox and gliding horse, and the Eight Trigrams Formation, building Shu Han into a modular military powerhouse. He sends Guan Yu to besiege Fancheng and tie down Zhang Liao, while personally leading a great army to secure the western reaches of Guanzhong. He joins forces with Ma Chao to take Liangzhou, applying pressure on two fronts to force Cao Cao to attack Wu. After eight years of strategic preparation, he sweeps across the realm with his hard-nosed military strategy, ends the age of chaos, and restores the Han dynasty's unity over all under heaven.
