Previously, Zhao Hai had been worried about the God race's javelin attacks. Now, however, he no longer had such a problem. Kelun's defensive magic array had already been developed. Once it was developed, he would use it.
As soon as the God creatures threw their javelins, a red, translucent shield suddenly appeared around the undead creatures. The moment their javelins touched the shield, they were burned to ashes.
Currently, Zhao Hai had a lot of fire crystals, so he gave the undead the cannons. At the same time, he wanted to test the defensive magic array.
The defensive magic array's defensive capabilities didn't disappoint Zhao Hai. The spears thrown by the Protoss didn't even hit the barrier. Instead, the spears were burned to ashes. This was a Testament to the barrier's strength.
