Do You Know That He Traveled Through Time and Became the Second Son of the Gu Family?

(Systematic, absolute force) The modern soul accidentally traveled through time and became a branch of the Gu family in the world of "Know or Not" - the bullied concubine Gu Tingchen in the second room that was not mentioned in the original work. At this time, he had just "escaped from death" from his brother's trap. His mother, Aunt Liu, was weak and could be bullied, and his sister, Gu Tingyue, was trembling in the deep house. The second old lady, Shen, who was born into a noble family, regarded the mother and son as a thorn in their side, and wished they could get rid of them quickly. The feud for the title of "Uncle Weiyuan" is surging undercurrent, and the two direct brothers each have their own agenda. The fate of the second brother of the Gu family seems to have been laid out for a long time. But they don't know that Gu Tingchen is no longer the cowardly young man who can be manipulated by others. Soul travel is bound to the sign-in system. Sign in at the Sheng family banquet and get basic military force; Gu Tingye signs in during the imperial examination turmoil and gets a hundred stones of food and grass; sign in when the border war breaks out and exchange it for an improved crossbow... As the plot of "Know or Not" progresses, he accumulates destiny points in key events, exchanges for magic weapons, ways to strengthen the army, and even leverages the wisdom of the court structure. From backyard fights to political struggles in the previous dynasty, from surviving in the cracks to rising to prominence, Gu Tingchen looked at the manipulated chess game in front of him and sneered: "It's time for me to walk the path of the Gu family by myself. It's time for this title and this world to live in a different way!" Let's see how the concubine counterattacks and relies on the sign-in system to take control of the second room of the Gu family step by step in this treacherous era, and then affects the entire Gu family, eventually gaining power and living a different life.
