The mobile phone of Lin Chen, a lying young man, mutated and became an errand running system dedicated to receiving "orders from all realms". He gave beer to Li Bai and love letters to Diao Chan, until he took on a long-term mission: traveling to the Republic of China every night on the same day to send "hope" to the famous theater actress Su Wanqing who was in a state of death. He used anti-wolf spray to deal with the spies, and played "The Internationale" on his mobile phone to inspire people. He used the unreliable methods of modern people to rewrite the ending of her destined sacrifice time and time again. But every time the clock strikes midnight and the world resets, she forgets about him. When Su Wanqing finally remembered this "errand boy" who always appeared in times of crisis, the correction power of time and space also surged. During the last time traveling, the ultimate order faced by Lin Chen was: "Please help her achieve the most beautiful ending." This time, what was delivered was not the goods, but the remembrance that a hero of the era should have, and a two-way redemption across time and space.
