If it were anyone else as the Master Priest of Huayu Temple, he would never have said this. Being able to become the Master Priest, one's understanding of the Law and Divine Arts wouldn't be lesser than his, so there'd be no need for his reminder. But Mu Hanyan is not just anyone. Sikong Qinglan had already guessed part of her background early on. Through this period of interaction, it's evident that although Mu Hanyan's natural talent is astonishing, her understanding of Divine Arts is still somewhat shallow, likely due to the influence of her prior cultivation. So, he gave this reminder.
Upon hearing Sikong Qinglan's words, Mu Hanyan's eyes lit up. Sikong Qinglan had guessed correctly; her understanding of Priest Divine Techniques was indeed heavily influenced by Sword Dao cultivation. Although in the Late Stage of Sword Dao cultivation on the Holy Court Continent, Laws are also involved, the key measure of strength is still Qi, not emphasizing the interplay among Laws.
