I recommend the following three novels to you: 1. " Enter the Movie " was also about the infinite universe, but just like " Hacker," the writing was clean and the pace was tight. The protagonist grew from an ordinary person to a powerful character step by step. At the same time, it also revealed some problems in reality. It was very worth reading. 2. " My Hacker's Life ": Although it was about urban life, it also described some details of hacker culture. It was also similar to the style of Qingmu Mountain. It was imaginative and interesting. 3. " Interstellar Hacker: The Battle of Wisdom ": It was a sci-fi genre like " Hacker," but it focused more on the battle of wits and competition between hackers. There were many exciting stories that happened on different planets. Reading it would make one think about the meaning of hacker culture and the relationship between hackers. I hope you like my recommendation.
