Tang Dynasty: After living together with Chang Le, Li and his companion were dumbfounded.

If one day, your room suddenly connects to the Tang Dynasty, what would you do? Lu Chen's first choice was to close the door. But he couldn't. Time and space tore apart, and his rented room was split in two. On the left were his computer desk, takeout boxes, and air conditioner. On the right... was a mahogany carved bed, embroidered curtains, and a stunningly beautiful woman pointing a dagger at him. "Who are you! Why are you in this princess's bedchamber!" Princess Chang Le of the Tang Dynasty, Li Lizhi, the most dazzling pearl of the Tang Dynasty, was now sharing a room with him. History records that she was frail and sickly and died young. Lu Chen looked at that pale yet radiant face and remained silent for a long time. Then he went to the pharmacy and bought three large bags of medicine. "What are you doing?" Chang Le frowned. "Saving your life." From that day on, Chang'an City had many new gadgets. A miraculous medicine that could cure all diseases, white sugar that could adjust all flavors. Fine salt, a divine grain capable of yielding a thousand catties per mu. Li Shimin was shocked, the court was shaken, and envoys from all nations knelt in worship. Everyone wanted to know where these things came from. Only Chang Le knew—the man who brought her milk, cooked instant noodles, and draped a coat over her every day came from fourteen hundred years in the future. On the day Changsun Chong came to propose marriage, Li Shimin asked her, "Chang Le, are you really not going to marry him?" Chang Le clutched the hand warmer Lu Chen had given her and smiled. "Father, in this life, I will only marry one person."
