Xiao Junyi, the Dinghai Shenzhen of the Daqian Dynasty, swept through the wilderness with one person a hundred years ago, establishing the three hundred years of the Daqian Dynasty. However, the prosperous age was peaceful and the hero was dying. He took off his armor and retired to seclusion, and his reputation was gradually forgotten by the world. Nowadays, Daqian is experiencing internal and external troubles, barbarians are knocking on the gates, treacherous ministers are in power in the court, and Xiaoxiao is running rampant. The young emperor actually regards this marshal as a threat. An imperial edict summoned Xiao Junyi, who had lived in seclusion for hundreds of years, back to the capital. It was called a reward, but it was actually a reduction of power. Everyone in the civil and military circles of the dynasty thought that the rumored marshal was already decrepit and wanted to take the opportunity to humiliate him. However, the moment Xiao Junyi stepped into the Golden Palace, they realized that what they had awakened was a sleeping dragon. The commander-in-chief returns and the storm rises again. This time, he not only wants to wipe out the foreign enemies, but also wants to wipe out this decadent court!
