If Zhao Hai wanted to waste his time with the sea beasts, he naturally could not do it quietly. For every sea beast he killed, he would release one or two sea beasts and let them discuss his decision with the others. For every sea beast he saved, he would kill one. Let's see what you can do.
Zhao Hai had his own reasons for doing so. He wanted to use this method to drive a wedge between the sea beasts and the demon God. Zhao Hai knew very well that the reason the sea beasts were following the demon God was probably because they had been affected by the Eye of the Beast King's spell. However, the Eye of the Beast King's spell could not be considered a spell. It could only be considered a suppression of the bloodline. It was like a mouse facing a Lion. Naturally, it would not resist. They would naturally think that the lion was their King. This was the reason.
