Undead creatures had always been Zhao Hai's most convenient servants. However, in the soul world, he had used them as well. Because he had never used magic before and there was no space, he couldn't turn the dead into undead creatures.
But now, he found out that the magic array could be used here, which meant that he could turn the dead into undead creatures through the magic array. However, it would be a little difficult to let the dead retain their memories and strength from when they were alive, just like in the space.
However, if it was necessary, Zhao Hai would still do so. Zhao Hai also understood that the other party was determined to deal with him. He had never thought of killing the two of them now. If he killed them now, it would cause a lot of unnecessary trouble. Therefore, he waited and at the same time, he wanted to give them a chance.
