Tomb Robbery: Intercepted at the Beginning!

Wu You made a deal with the system. The system would help him get revenge, and he would help the system complete its mission. After traveling through time, he discovered that the system was actually a human being. Wu You saw the system's life, and his remaining vigilance towards the system disappeared. But later, as he got along with the protagonists, Wu You discovered that the system was still hiding many things from him. This is my first time writing a book. The author is very considerate. You can ask questions and I will try my best to correct them, but you can't scold me. There is no female protagonist in this book, there may be two male protagonists or three male protagonists.
