Tomb Raiding: Ambushed from the Start!

Wu You struck a deal with the System: it would help him take revenge, and he would help it complete its missions. After transmigrating, however, he discovered that the System was actually human. Seeing the System's entire life made Wu You let go of the last of his wariness toward it. But as he spent more time with the protagonists, Wu You realized that the System was still hiding many things from him. This is my first time writing a book, and I'm pretty sensitive, so feel free to point out problems and I'll do my best to fix them, but please don't insult me. There is no female lead. There may be two male leads, or possibly three.
