Enter the Vikings and Become a Overlord

In 876, on the Scandinavian Peninsula of Northern Europe, the transmigrator Su Chen becomes a Viking named Ulf. He recites chapters from The Lord of the Rings to the Viking barbarians, persuades with violence, conquers the tribes of Scandinavia, and finally stands with sword in hand, armored, beneath a dragon-prowed warship, challenging the nations of Europe. Behind him, Viking berserkers are eager and waiting for his command.

Ulf: Wherever the dragon prow reaches is the land of Odin. Burn down the churches of the heathens and seize all their wealth.

Bjorn Ironside: Your achievements will surpass my father.

Ivar the Boneless: This guy Ulf is actually even more cunning than me.

Halfdan the White: Overlord Ulf, I am willing to submit to you.

The Byzantine emperor: Esteemed Ulf, my brother, please hurry and bring your army to help. Money is not a problem.

The sultan: Damn Ulf, he has blocked my great cause.
