It was precisely because of this thought that Zhao Hai did not want Edison and the others to die in vain. Thus, from the very beginning, Zhao Hai had set up a plan to strike down the morale of the underworld God temple so that the pressure on Edison and the others would be reduced.
This time, Zhao Hai's campsite was not an ordinary campsite. He had treated it as a fortress built by the Protoss. Not only did Zhao Hai use earth magic to build a hundred-meter-tall stone wall, but he also installed magic cannons on the wall. He also took out the blood Thunder balls, javelins, and even the bed armor. It was everything that could be used against the enemy. Zhao Hai was not stingy and took out everything.
The blood Thunder balls in Zhao Hai's interspace had also been upgraded. Not only did they contain a huge amount of energy, but they also contained a deadly poison. The poison was from the Black Sea of the underworld and was very lethal to the undead creatures.
