After Chen Yuan's sudden death, he traveled back to ancient times and became a sick and weak scholar in an ancient deserted village. His family had only four walls and no fields. He gritted his teeth and picked up a hoe to open up wasteland for farming, and picked up a cold-faced woman with injuries all over her body and amnesia by the river beach. Her name is Shen Shuanghan, she is the daughter of a famous northern general who was falsely accused. She suffered a blood feud and fled thousands of miles away. The two lived together in a broken hut. She taught him how to hold a knife, and he taught her to trust.
When the officers and soldiers came after her, she rode her horse to divert the pursuers. He put his bow on his face and walked out of the rice field that she could see at a glance when he came back.
From Nanxi Village to Yingzui Gorge, from Lieutenant General to Protector of the Northern Territory, Chen Yuan used account books and maps to turn a piece of border wasteland into the strongest barrier in the Northern Territory. The trade route ran from east to west, the iron smelting furnaces were kept running day and night, and the Xianbei cavalry from Lianzhou, Hongzehu, and Huyanchina were drawn into the battle one by one. And when the strategist Xiao Muller, who had met his opponent, emerged from the Beidi Royal Court, Chen Yuan discovered that the real game was never on the battlefield, but behind every secret letter, every trade route, and every hidden stake.
"It took him five years to get from chess piece to chess player. Now, it's his opponent's turn to make the move."
