On the east coast of Greenland, it's polar night, minus 40 degrees Celsius.
Norwegian maritime archaeologist Lena Berg followed the scientific expedition team deep into this ice sheet swallowed by eternal darkness, and discovered a well-preserved Viking longship deep in the fjord. The ship was more than a thousand years old, but it sank like an elaborate funeral.
The hull is covered with ice, and the runes on the hull are engraved with a warning:
"This ship buries not warriors, but what warriors bury. Those who touch it will awaken the wrath of iron bones."
But Einar, the sponsor's representative, couldn't wait. He urged the diving team to dive down immediately, turning a blind eye to the layers of ice-encrusted remains of Viking warriors on the side walls of the ship.
Immediately afterwards, the corpse crawled out of the ice!
Wearing chainmail from a thousand years ago, with dark blue flames burning in his eyes, dragging a rusty battle ax and long sword, he staggered towards the camp!
They whispered under the cover of the polar night, calling out a name - Harald "Ironbone", a Viking king who volunteered to bury something in chains with the death of three hundred warriors!
