Operation method
First of all, we must obtain a new map, that is, a new map of the Demon World, or it will be impossible to complete.
Demon Blade Village Zheng's sword has powerful attack power and a critical hit rate of points. Although it is not as good as other swords, if we have this sword, we can cut some ghosts effectively, so it is worth having!
If you want to burst the demon sword, you still need to go back to the new map mentioned in the first step. The probability will be higher if you burst it in the Devil Kingdom abyss!
