The Powerful Official in the Troubled Times of Time Travel

He traveled through time and space to the darkest days of the Northern and Southern Dynasties. Without aristocratic background, no help from noble people, he can't even have a full meal. But he has an ability that no one else has - he knows where history will go in the next fifty years. Hou Jing's Rebellion, the Battle of Jiangling, the Northern Zhou Dynasty's destruction of Qi, Yang Jian's replacement of the Zhou Dynasty... He was aware of every major event. While others were fighting for petty profits, he was already arranging the world. He selected strong soldiers from the refugees to train, he used "Chengcheng rice" to feed the people, and he used gunpowder to blow open the strong city gates. Every step we take is preparing for the war ten years later. Some people say he is a lucky gambler, others say he is a monster who knows the secrets of heaven. Only he knows that there is no unearned victory in this world - every step of rise is paid for with life. When the last heroes of the Northern and Southern Dynasties came to an end, people discovered that this young man from a poor family who once had no enough to eat had already stood at the pinnacle of power.
