Jia She Served as His Concubine's Brother and Escaped from the Dungeon at the Beginning by Breaking the Lock

Chang Wei, the younger brother of Jia She who died as a concubine, was locked in a dungeon and almost starved to death. Turning over the first page of the heavenly book, Jia She's head was hostile to 85, and he was rewarded with a thousand catties of strength. After smashing the cage and escaping, he found a den of rat thieves and found out that someone was paying to destroy the Rongguo Mansion cavalry. The water in Jia Mansion is deeper than I thought.
