Finally, there were naval mines. Because water was a conductor of electricity, naval mines would be more effective than on land. Before, people used to use this method to blast fish, killing many with each blast.
However, this was not commonly seen anymore, as it was quite dangerous. Moreover, this was also quite cruel, and those who did it would be called out to be immoral.
Zhao Fu did not have naval mines, but he had two human nukes, who were Binoche and Kerache. In the defensive battle, Zhao Fu had heard of their performance, launching a combined forbidden spell that had blasted out a ten-kilometer-wide crater, making it so that millions of soldiers did not dare to approach.
This time, Zhao Fu wanted to rely on them to seal that forbidden spell into an item. If they could do this, simply throwing that item would be able to unleash the forbidden spell's power, which would be incredibly effective. This would be similar to a magic scroll.
