Cheng Guang thought of this and was again slightly puzzled.
After all, returning to the previous point,
the primordial spirit of Dongfang Chiguo Tianwang contains the heavenly laws.
Why then does Erlang Shen, Yang Jian's primordial spirit, lack the existence of heavenly laws?
Could it be...
that Erlang Shen, Yang Jian, has never been constrained by heavenly laws?
Cheng Guang thought of this and then remembered that Erlang Shen, Yang Jian, after all, is at odds with both Heavenly Court and the Western Buddhas.
Moreover, in the true timeline of the Princely Heir, he could even request that real Princely Heir to become an enemy of Heavenly Court.
Therefore...
Erlang Shen, Yang Jian, has never aligned himself with Heavenly Court.
It's quite normal for his mind to be free of the constraints of heavenly laws.
