Three Kingdoms: From the Start, I Raise Lu Bu

[Transmigration + character development + ensemble struggle for supremacy] A burned-out office worker transmigrates to the third year of Jian'an and becomes a groom in the Xuzhou governor’s residence, where he activates a “Military General Development Panel.” First, he nurses the gravely wounded Lü Bu back to health, then takes in the young Zhao Yun and Dian Wei as sworn younger brothers, while training Diaochan and Zou Shi to become female military strategists. Starting in the stables, he tames Red Hare, forges steel crossbows, and assembles the Trapped-Camp Battalion. He gradually gathers all five tiger generals of Shu Han and all five elite generals of Cao Wei, then leads an all-star army across the realm, raising the Han banner once more at Yumen Pass!
