Because XZ needed to help the 36 Caves/72 Islands members remove their Life-Death Talisman, he worked very hard on his Tian Shan Liu Yang Palm, and has become familiar with all its variations. And the pictorial instructions engraved on Lingjiu Palace's basement wall also allowed him to gain a deep understanding in this technique. But since he has never used it against another person before, he lacks practice, and now in his first fight he is up against one of the top fighters, so even though his palm technique is really advance, his inner power is really strong, he is only able to use it at 20-30% effectiveness.
