Five Cents Bought an Ancient Civilization

In Luojing City of Daqi Dynasty, there was a loser who failed the exam for three consecutive years. His name is Lu Feng. He ranked last in the entrance examination of Mo Institute of Technology, his classmates laughed at him, his fiancée's family broke off the engagement, and neighbors would only shake their heads when mentioning him - "his father's face was completely embarrassed by him." His life seemed destined to rot in the mud in mediocrity. Until he bought a tattered map for five cents at a used bookstall. That night, the map glowed. An ancient treasure called "Atlas of Mountains and Rivers" awakened in his hands. The map seals the lost technologies of the ancient civilization of Canglan Continent - metallurgy, machinery, formations, medicine... Each of them is enough to shake the structure of the entire continent. Tupu told him: Three days later, Qingya Pass in the north will be attacked. He ran to report it to the police and was kicked out. He ran to report the news and was laughed at as a madman. He could only stop it in his own way - posting anonymous information in the Bounty Pavilion, being chased by spies from the Western Regions, smashing the enemy's face with a brick in a dead end, and escaping with blood all over his body. That night, something really happened at Qingya Pass. And Lu Feng is no longer that good-for-nothing.
