In his previous life, Liu Baorui was the sharpest sword of the Dayao Dynasty, sweeping the world and establishing the kingdom for the new king, but in the end he ended up with the king of great achievements being poisoned to death by poisoned wine. Full of unwillingness, he was reborn and returned to 20 years ago, where his mentor was about to be executed by the faint-hearted king and powerful ministers. Enemies outside the northern border were mobilizing troops, and the dynasty was already on the verge of collapse. In this life, he is determined not to be a weapon at the mercy of others, but to put things right out of chaos with his own hands, to protect his mentor and the mountains and rivers thousands of miles away.
The court is controlled by five powerful clans. The civil and military officials of the court are obsessed with party fighting to amass wealth. The young emperor ignores political affairs. Liu Baorui, a low-level general, must not only raise food and fodder to prepare for war within three months to resist the invasion from the north, but also must open a reform gap in the court despite the overwhelming impeachment of the family. Once he fails, not only will his mentor die, but the dynasty will also be overthrown, and he still cannot escape the fate of death. Liu Baorui holds the memory of rebirth in his hand, knocks on the palace door at night to present the late emperor's edict, toughens the ministers in the Golden Palace, fights his way through internal and external troubles, and vows to turn the tide and rewrite his destiny.
