Three Kingdoms: My Soldiers Are Unstoppable

Transmigration + Three Kingdoms + invincible protagonist + beauties + System Lin Feng woke up to find that he had transmigrated to the end of the Han Dynasty and was being kept in a cage like livestock. But this Han Dynasty was somewhat different from the one Lin Feng knew. The Han Empire was surrounded by powerful enemies: to the north were the Wuhuan, Xianbei, and Xiongnu Empires, as well as the Korean Empire; to the west were empires such as Kushan and Parthia; to the south were empires such as Daxia, the Peacock Dynasty, and Annan; and there was even a Cherry Blossom Empire across the sea. Fortunately, Lin Feng awakened a System. He eventually rose from a lowly slave to become a hegemon, wiping out the wolves around him and founding a vast empire.
