Master O Britain (不列颠之主）

Translation of a Chinese web-novel, original author 巧合巧 (qidian)

The Vikings are back!"
"Kill them all."
"Ragnar is here!"
"Kill him too!"
......
The Middle Ages, 865 A.D., a young baron was born in the north-central England.
He saw the Vikings' invasions, saw the northern border in the era of chaos.
And so he took their skull cups, looked at the heavens, and mocked the gods for abandoning England.
