Three years after Jiang Yiyun ascended the throne, the Queen Mother Dugu Ping forced him to kneel down and read out the imperial edict before he could sit on the throne. All civil and military officials in the entire dynasty were lackeys of the Dugu family, and the secret passage in the palace led directly to the residence of his relatives. What is even more desperate is that there was a severe drought in the Xuanhuang Dynasty for three years, the granary was at its bottom, and the people changed their sons to eat. And he, a time traveler, couldn't even mention modern agricultural knowledge - if he did, he would be obliterated by the World Tree. Until that day, when he was so hungry that stars appeared in his eyes, a translucent panel suddenly popped up in front of him: [Historical Game Mall] has been bound to the host. It can be exchanged for high-yielding sweet potatoes, curved plows, fertilizer formulas... But each item must be activated with runes. As for runes, they need to be sacrificed - one finger for a 'harvest rune'. Jiang Yiyun looked at the dagger and smiled. He cut off his little finger and carved the first rune on the dragon vein stone tablet. Overnight, the imperial palace's back garden produced thousands of kilograms of crops per acre. Dugu Ping was shocked and his relatives were frightened, but the hungry people all over the world began to sing: "The emperor has divine help." And he was using the second rune to exchange for a shadow peasant army... While his relatives were still fighting for power, Jiang Yiyun had already filled the entire dynasty's granary with the hopes he had 'bought' from the mall. But no one knew - there were only four fingers left on his left hand.
