Kapitel 1608: Modifying the black Yin Thunder (1)

That was the dark Yin lightning, not some random rock on the side of the road that could be picked up and used to hit people. The dark Yin lightning was very famous in the cultivation world for two reasons. First, it was difficult to make, and second, it was very lethal.

But now, Zhao Hai had taken out thousands of them. Since when did they become so cheap?

Zhao Hai was very satisfied with the results of this battle. However, he was not satisfied with the fact that the harvest was too little. To be honest, Zhao Hai did not expect the black nether lightning to be so brutal. It actually killed more than a hundred people in one go. Those people were all experts with magical weapons.

On the other hand, Zhao Hai was very satisfied with the undead creatures 'performance in this battle. The undead creatures were doing well, especially after they were given the abstruse Yin Thunder, which increased their combat strength by more than a level.
