Zhao Hai had told Muyu before that he had many undead creatures that could control the formation-breaking spiritual snake needles. Muyu believed that Zhao Hai would not lie about this. Zhao Hai said that he could add 10000 undead creatures to each of the formation-breaking spiritual snake needles and Muyu believed that Zhao Hai could do it.
However, he didn't ask Zhao Hai to release a million undead creatures, so he didn't know what would happen after that.
Now that Zhao Hai had really released the one million undead creatures, the overwhelming number of them was truly hair-raising. Anything that reached a certain number would be terrifying, not to mention these undead creatures. These undead creatures were like humans. Imagine what a million-strong Army would look like.
As the saying went, " there's no end to ten thousand soldiers, " but there were a million soldiers here. A million soldiers, even if they knew that they were their own people, it was still very shocking.
