A top-secret experimental explosion transports Xiao Ming to a parallel world resembling ancient times. In this hostile land, he is the most unfavored prince, given the most barren fiefdom. Fortunately, however, a mysterious item from the experiment—the Technology Crystal—comes with him, granting him the ability to upgrade a technology tree.

Thus, he begins a leisurely life in his fief, farming and developing industry. In the face of his unfriendly brothers and sisters, he has always followed the motto- friends come and get wine, jackals come and get shotguns.
