The Four Essence Pearls

Zhang Yang was charging forward against the direction of the wind current. He was sweating so profusely that his sweat was dripping down across his face as if he had just come out of water. For every single second, his mind was set to calculate and predict. Well, any slightest mistake he makes will doom him to pieces. Using his brain power over a period of time was exhausting as f*ck. Zhang Yang felt dizzy, as if he was about to pass out.

He was on the verge of losing his focus now!

Just when his face became pale as snow, he saw that his front view became clear and sunny. There was a stone room with the size of 40 to 50 meter-square with a boulder in the middle of the stone room. There was a snowy white large bead placed right on top of the boulder. It was about the size of a fist.

That must be the Wind Essence Pearl!
