Moving house (2)
It was already very difficult to set up a plane array, especially for such a large plane array.
Apart from Zhao Hai, no one else in the bewitching Empire had been able to complete such a large-scale two-dimensional array. It was not a good thing for the bewitching Empire to let everyone know the concept of a three-dimensional array. It was like a child who had not learned how to walk. If you asked him to run, and he ran ten thousand meters, it was simply impossible. If he did not do it well, he might even tire the child out.
However, although Zhao Hai could not teach them the idea of the three-dimensional array, he could let them try to set up a two-dimensional array. As long as they could successfully set up such a large two-dimensional array, it would be a great success for them.
