In the autumn of 2001, Chen Qiu, a high school boy from a county town, skipped class and walked into an internet cafe. There, he saw the city of Bicheng on a screen for the first time. He registered a Taoist character named “Autumn Wind,” and from then on, his life became entwined with this virtual world. Leveling up, fighting, storming the fortress, swearing brotherhood, online romance, betrayal, parting... Over the next twenty years, he experienced the ups and downs of friendship and love in the game, while enduring the growing pains of rebellion and maturity in real life. When the flag of Shabak fell and the names on his friends list turned gray one by one, he finally understood: Legend had never faded. That wind had been blowing for twenty years, and it still hadn't stopped.
