When he discovered the uniqueness of the Twin array patterns, it was as if he had suddenly found the end of the thread in a mess. Many questions that he had in the previous ten to twenty hours of analysis seemed to suddenly become clear.

"It's not complicated even if you understand it!"
"These two basic array runes can actually be used like this ..."
Xia ruofei kept muttering to himself in amazement. He was getting more and more familiar with this array that could form a tough barrier.
It was like a complicated math problem. Before finding the solution, one might not even understand the problem. One would not know what to do with the conditions given in the problem.
