Time-Traveling X

This is a solid guide to survival in time travel. There is no power struggle among royal families, no life-long personal inheritance from worldly masters, no eye-catching glances of peerless beauties, and no overt and covert attacks by enemy politicians. Some just want to eat tomorrow? Where to sleep tonight? How to live the days when you can't go back? And weasel, get away, I can't beat you.
