Shi Hao himself has exceptional comprehension, and after cultivating the Primordial Scripture, he has an even deeper understanding of the essence of heaven and earth compared to others.
And what about the Wordless Spell?
To a certain extent, it has already touched upon the essence of heaven and earth!
Ding Lingfeng probably has not cultivated the Primordial Scripture. He relied on living life after life, comprehending the mysteries of life through death, and perceiving the true knowledge of death through life, gaining insight into the origin of heaven and earth in this way.
If one truly masters the origin of heaven and earth, how different would they be from heaven and earth?
It can be said that even if someone from the Immortal Realm comes, they could be easily suppressed!
I am heaven and earth, naturally invincible.
Pushing it further up, if one can also master the origin of the Immortal Realm, then they would be invincible in the Immortal Realm.
