In this world, Cultivators' battle prowess depends on many things, like Cultivation Talent, Bloodline, Special Skills, and Cultivation Techniques.
Awakening Cultivation Talent, Bloodline, and Special Skills depend on luck, and through extremely hard work and a bit of luck, they could awaken them.
However, Cultivation Techniques are the only thing that is relatively much easier and more accessible for all cultivators.
As long as one trains properly, they can increase the mastery of their cultivation techniques and become powerful enough to change their fate.
So, despite having Bloodlines, Special Talents, and Special Skills, Ethan never thought of abandoning his cultivation techniques.
Thus, after learning that he could now upgrade the cultivation techniques beyond the Perfection Stage, Ethan didn't hesitate to check the cost to upgrade them.
Of course, Ethan wanted to check the cost for the regular cultivation techniques before checking the Heavenly Techniques.
