Upon seeing those ten characters, Sun Wukong felt as if struck by lightning. Though it was merely ten characters, the shock they brought to Sun Wukong was unparalleled. "Flower Fruit Mountain, a blessed land; Water Curtain Cave Heaven." In this world, there was no one more familiar with these ten characters than Sun Wukong. In fact, he was even more familiar with these words than with himself.
It was Sun Wukong who initially leaped through that waterfall and discovered the Water Curtain Cave. Since then, the Monkey Tribe was sheltered from the wind and protected from the rain. So, the appearance of these ten characters here, could it mean that the mountain before him was Flower Fruit Mountain? That waterfall, was it the Water Curtain Cave?
