The difficulty for learning 【Crescent Moon】 was much higher than Ai Hui had expected.

Although it only involved two palaces, Ai Hui tried for a long time but still could not find a way to start. Thanks to his frequent discussions with his teacher, his horizons had been greatly broadened. Wang Shouchuan was good at working with theories and often discussed them with Ai Hui, even though he knew Ai Hui was only a beginner.

In fact, moves involving only two palaces were mostly basic moves. They were simple and easy to learn, but had limited power. Since not much elemental energy was needed, the flowing route was simple too. As a result, such skills could not involve many changes.

It was like cooking. If the cook had only two ingredients, he would have very few choices in how to use them, and therefore could not prepare complicated dishes.

That was why he believed that Cheng Rou, who could create the skill of 【Crescent Moon】 within the hand palaces, was definitely a genius!
