After Marrying the Male Protagonist's Guard, He Was Forced to Join the Main Plot

As we all know, all male protagonists have one or two guards who are more like brothers than brothers. And I, Xiao Mengmeng, a future immortal cultivator who accidentally crossed into the wrong world on the way to time travel, found a partner in ancient times, and unexpectedly she turned out to be the male protagonist's bodyguard. I have always wanted to stay away from the main line and was forced to get involved. Is it because God has plotted against me? I wonder if there is a backer behind me. Otherwise, why is it that I am the only one in the world who can travel across the world? Forget it, fight first, then settle the score! [Although it is said that there are male and female protagonists in the world that the heroine travels to, the heroine does not know the plot. The heroine knows about the existence of the original heroine, and Tiandao told her.
