A common man from the 21st century named Jax travels back in time and becomes the weakest warrior among the Vikings. After awakening a system, he marries three wives: a princess, a general’s daughter, and a merchant’s daughter. Rising from the bottom of the tribe, he subjugates four major tribes, eliminates his enemy Byron, and secures a firm foothold in the Northlands. In the end, his wives are abducted, and a new storm looms.
