The Whole Class Traveled Through the World of Cultivating Immortals, and I Arrived Last

I have traveled through time, or rather the whole class has traveled through time. My classmates have been here for three hundred years, and I don't know how many of them died before I traveled through time. Useless system, brother who died early... "You mean you are old enough to be my ancestor?" "It's okay, I said I am your father, no matter how old I am, you will always be my son."
