Half a month passed.
Instead of studying the Ocean Book in a hurry, Han Fei refocused his attention on the Spirit Gathering Scripture that Old Jiang gave him.
The Ocean Book clearly had many more arrays than the Spirit Gathering Scripture did. It was much more complicated and harder to learn than the Spirit Gathering Scripture, a systematic tutorial.
Fortunately, after only half a month, Han Fei was already able to paint most of the arrays on the Spirit Gathering Scripture with one touch.
The more complicated arrays were usually combinations of simple ones. All he needed to do was to turn the small arrays into lines and regather them.
At this moment, Han Fei was painting a new array. He completed a pattern with nine lines.
Han Fei didn't seal the array with his spiritual power, but simply threw the fish skin out casually.
Immediately, an array of a hundred meters wide appeared, with auras surging inside.
