At this moment, his appearance had transformed into that of the Xuling Taoist by using the Intangible Skill, but upon reaching the gate of the Xuling Sect, he decided to change his plan.
If he entered the sect disguised as the Xuling Taoist, it was highly likely to arouse suspicion from those in the Daoist Fruit Realm who knew the truth, potentially awakening the Supreme Elder prematurely. Although he wasn't afraid of battle and could annihilate the entire Xuling Sect, he wouldn't be able to achieve all his goals; it would be the most brutal method with the least return.
Another method was to infiltrate and, with his skills, transform all ordinary Dao Realm and even Daoist Fruit Realm cultivators into Wan Ming Incarnations without anyone noticing. By then, when he made his move on the Supreme Elder, he definitely wouldn't fail.
