Eternal night fell, the North Sea froze over, and humanity relied on the earthfire of Youdu Mountain to survive.
On the mountain, seven great sects fought over the fire vents and trained cultivators.
Below, a mysterious forbidden zone held a group of sea demons that could not be killed.
Li Xiu was just a poor apprentice who repaired pipes. The night sea demons attacked the shore, he fell into the frozen sea and clung to a little black beast on the verge of freezing to death.
To survive, the boy and the beast formed a pact.
The little beast was as fat as a dog and loved eating furnace ash. Li Xiu called it Xiao Hei, thinking he could have it tend the fire and earn a few extra copper coins.
Who knew it could grow by devouring fire energy, then feed the refined spiritual energy back to its master?
Li Xiu began cultivating. Thanks to his astonishing talent for controlling fire, he became the alchemy saint’s personal disciple. As he and Xiao Hei traveled farther afield, refining pills, competing in martial arts, and exploring the North Sea, they gradually drew the attention of all sorts of factions.
What exactly is hidden in the forbidden zone deep inside the mountain?
