If you delve deeper, you will vaguely see "secondary black technique technology sealed...".
What is being nurtured within it is precisely the law he is to establish after breaking through to the Refining Void Realm.
Once successful, all Immortal Path technology extended and deteriorated from black techniques can also be sealed for a certain time and within a certain range.
Luo Wujie knows that the faction he has been part of these many years has expanded the scope of technique sealing step by step to lift the Taoist Inheritance, and spread the power of the Taoist Inheritance.
To break through to the Refining Void, besides one's own abilities, talents, achievements, and resume, the most important point is the choice of the law.
Only when the law is in harmony with the Taoist Inheritance, able to integrate into it and lift it, will one be favored by superiors and have the opportunity to break through to the Refining Void.
