Shi Hao and Shen Yuexin couldn't enter, because they had only unlocked the formation of one building, and many others still needed their attention.
To be precise, it was mainly Shi Hao who was busy, while Shen Yuexin could only assist.
She was willingly serving such a master, as she could benefit greatly from it.
Shi Hao spent only half a day to unravel all the formations here.
Initially, the Purple Gold Rat intervened, which shouldn't have taken so long, but upon reaching the later formations, Shi Hao wanted to test if he could solve them independently, so he didn't ask the Purple Gold Rat for guidance.
He used the Primordial Scripture, looking at the issues from the perspective of the world's essence.
Although this is a Mortal Level Primordial Scripture, since most things in the Immortal Realm are at this level, analyzing the subtle changes in a Mortal Level environment can provide very useful references.
