Wang Yang wasn't entirely unfamiliar with the Great Dao of this world.
After all, he was quite familiar with a portion of the Dao.
For example, space and time, which are basically essential components of the Dao in every continent.
However, in the Three Realms, these Daos might be one of the Fifty Great Daos, but here, they could only be reduced to being members of the Minor Dao.
It was precisely because of this that Wang Yang's comprehension progress had slowed down a bit.
Fortunately, with the Heart of Pangu, Wang Yang's Primordial Spirit didn't focus on comprehending the Dao on the protective membrane, instead concentrating on the Dao that had been imitated by the Heart of Pangu.
As a result, Wang Yang's efficiency in comprehension naturally improved greatly.
Although Wang Yang had not yet fully comprehended any Dao of this world, he had more or less a clue and wasn't completely in the dark.
