An enormous complicated array appeared .
While Zhao Feng was merging the forces, he didn’t give up on comprehending the structures of the Hollow Building’s array.
Now he had analysed the structure of the array, but it was hard to fully control it. After all, even the best array masters had only understood 20-30% of it. But Zhao Feng had his own advantage and that was that he was able to see the array structure and imprint it in his mind.
Therefore, he had comprehended 70-80% of the array, surpassing all the other array masters.
