Tomb Raiding: Protecting the World I Fell Into, Where Tomb-Raiding Universes Converge

Zhang Haimo is an utterly ordinary college student, until he encounters something extraordinary: he transmigrates into a book. The good news is that he has a System. The bad news is that the book is Grave Robbers' Chronicles, which he has never read, so he has no idea how the story will unfold. Even the System is worried about his safety. His mission is to protect the protagonist, but the System is such a pain: not only does it refuse to help, it actively makes things worse. And this is only the beginning. The System has plenty more ways to trip him up. He starts out emotionally detached, doing nothing but completing his missions. But later, he begins to care on his own. What could have changed him so much? Let's find out together!
