Many weapons come into existence, most of which require a blood sacrifice to be wielded by man.
If the slain are the wicked and utterly depraved, then the weapon is righteous.
Otherwise, it becomes an Evil Weapon.
Although the power of an Evil Weapon is great, it is not the path of righteousness after all.
The more people an Evil Weapon kills, the more its master will suffer backlash, until eventually they suffer interrupted meridians and go mad from internal havoc, leading to death.
Seven hundred years ago in Shenzhou, there was an Evil Weapon known as "Blood Fury," which had passed through seventeen masters.
None of those seventeen highly skilled Martial Artists lived past the age of thirty.
Because the Evil Weapon Blood Fury indeed brought great power to Martial Cultivators, countless people coveted it despite the fact that the weapon was deadly to its master.
