Once he breaks through to the Dao-Confirming Tenth Layer, he will then cultivate the Defying Heaven Level Holy Technique.
The Defying Heaven Level Holy Technique is extremely difficult to cultivate. To cultivate it, he must at least break through to the Dao-Confirming Tenth Layer.
Yang Xiaotian takes the Tenth Layer of Dao Holy Water daily for cultivation.
While cultivating, he also has his subordinates, Zuo Meng, Li Gu, and others, to help him find out about the Dao Five Elements Holy Stone. He needs it to cultivate the Chaos Five Elements Escaping Technique.
Currently, his Chaos Five Elements Escaping Technique has reached the peak of the Twenty-Five Layer. To rapidly improve, he must rely on the Dao Level Five Elements Holy Stone.
Of course, Yang Xiaotian also waters the Time Divine Tree and several other Divine Trees with a sip of the Ninth Layer of Dao Holy Water daily.
