Jiang Xie Shen Jian plot
A cruel and impotent ruler does everything he can to find the best swords in the world, with which he can vent his frustration and sense of power on the enemy and his own people. When a local swordsmith discovers steel, he does everything he can to get his hands on a sword made of this rock-hard steel. The blacksmith is captured, furnaces are built, and to reinforce his threat, he also throws a child into the furnaces. The swords that the furnaces now produce, however, are animated with spirits that, of course, are not too pleased with the ruler.
