Reborn in the Tang Dynasty as Li Chengqian, with My Wife's Help I Claim the Throne

Other people transmigrate with a System. I transmigrated with a wife who only wants to “help” me? Li Chengqian opens his eyes to find himself the Crown Prince of the Tang Dynasty. He has no golden finger, only foreknowledge of history: a lame leg, deposition, and imprisonment until death. The whole package is already set in stone. Looking at Su Wan, his gentle and obedient Crown Princess, he decides to defy fate and change his future, starting by getting their marriage on track. But why does something seem off about his wife? He practices calligraphy, and she suddenly masters Wang Xizhi’s style: “Your Highness, allow me to grind the ink for you.” He discusses affairs of state, and she casually proposes economic policies centuries ahead of their time: “Your Highness, could we reform the state monopoly on salt and iron like this?” He is attacked, and she “accidentally” knocks the assassin over: “I was so frightened, my legs went weak...” Su Wan is even more aggrieved. She transmigrated into the Crown Princess and was bound to the [Virtuous Support System]. It has only one mission: help Li Chengqian ascend the throne, or all her skills will be locked. To make use of the System’s calligraphy crash course, palace intrigue encyclopedia, and modern management techniques, she has no choice but to orbit the Crown Prince every day, all the while ranting to herself: “I just wanted to trade points for a pack of sanitary pads!” “System, tell me, how am I supposed to use the ‘Basic Postpartum Care for Sows’ skill to help the Crown Prince?” “Li Chengqian, can you please try a little harder? I want to be empress so I can buy shampoo from the shop!” Two modern souls, each hiding their secret identity. One thinks his wife is a native-born virtuous spouse and tries desperately to act like a good husband from ancient times. The other thinks her husband is the real Crown Prince and works hard to play the gentle Crown Princess. Until one day... Cornered by political enemies, Li Chengqian blurts out, “Isn’t this just a PowerPoint presentation?”
