When I Woke Up: I Was in the Princess's Boudoir!

(Sweet writing without swords + rigorous plot + slow pace + not brainless + emotional flow) Lin Yu has traveled through time, what can he do if he is not a son-in-law without a system! ? When he came to this strange world, he originally wanted to sell wine to make money and live in peace for the rest of his life, but unexpectedly, the Qin Dynasty was on the verge of collapse. He went out with the army to defend the border and made great achievements, but unexpectedly he was framed by the courtiers and plotted by the emperor. He laid a clever plan and dealt with it rationally, but unexpectedly famines occurred frequently and rebellions broke out... Wen Neng can bring peace to the world with his pen, and force can control the world with his horses. Let's see how Lin Yu can save the building from falling and save the people from fire and water! PS heroine (the princess of Da Qin is arrogant and willful, the fairy master is cold and cold, the commander of the inner guard is charming, the general's daughter is dignified and delicate, the disaster girl is smart and cute...)
