Although this method was very easy, Zhao Hai wasn't optimistic about it. In his opinion, using a magazine was the best way. What he wanted to know now was the secret behind the guns and bullets used by the flame weavers.
However, this wasn't an easy task. Those flame weavers were very strong, and they started off with a spear attack from a distance. This way, even if Zhao Hai wanted to attack them, they could react in time and Dodge. Therefore, Zhao Hai's group didn't make much progress other than killing some of the other side's magical beasts.
Moreover, it wasn't easy to kill the other side's magical beasts. Those magical beasts weren't stupid. After being attacked by the array-breaking spirit snake needles, they also became more careful with them. It wouldn't be easy for those array-breaking spirit snake needles to kill them.
