Lin Wanwan, a transnational migrant worker, worked overtime until three in the morning. When his vision went dark and then he opened his eyes, he was standing in the Tai Chi Hall of the Tang Dynasty in his pajamas. The young emperor in brocade robes and dragon robes in front of her looked at her with raised eyebrows, while the imperial guards holding swords behind her stared at her with eager eyes. She could only bite the bullet and talk nonsense: I came from 1,300 years in the future, specifically to help His Majesty with infrastructure construction. From then on, the emperor yawned next to her, and the emperor ordered her to order milk tea for takeout. All the civil and military officials watched her use black technology to defeat the Turks, renovate the plough, and print newspapers in batches. They collectively doubted life. However, when the enemy troops pressed forward and the court was in turmoil, only she knew that the giant ship of the Tang Dynasty was about to sink. She held the history book in her hand, but found that she had unknowingly become the key to rewriting history.
