Gu Jiantang, a young man from a poor family, refined the "military rules" into a sword.
On a snowy night in the border town, he used a "frontal rule" to smash three thousand Hu Qi, and was involved in a thousand-year secret war between the five surnames and the Zhenbei Army.
From corps commander to historian, he forged swords and legislated laws, allowing rules, rivers and lakes, temples, and history to collapse and rebirth at the same time.
This is a long novel about "how people use their own heartbeats to rewrite the laws of heaven and earth."
It's a bit interesting and pretty.
Pretending to be mysterious...
