After hearing Li Changge's account, Xu Changxing's brows knitted tightly.
It was not because the matter was difficult to handle, but because the Tianyan Pearl had not shown it during the simulation.
This suddenly made him realize that this Grotto-Heaven seemed capable of blocking the Tianyan Pearl's simulations, just like the Eye of the Great Dao.
He vaguely felt that this might be because this Grotto-Heaven had been left behind by the Azure-Robed Dao Ancestor.
Given the Tianyan Pearl's grade, whenever a simulation involved a Dao Ancestor, it was very likely to be blocked.
If that's the case, could the Tianyan Pearl's inability to simulate the scenes within the Eye of the Great Dao also be related to a Dao Ancestor?
Xu Changxing had always thought that the Tianyan Pearl could not simulate the Eye of the Great Dao because the laws there were unusual.
Now, however, his view had changed somewhat.
Still, this was only his conjecture and could not yet be verified.

"In that case, I'll visit a few Small Worlds and recruit some cultivators from the Mortal Realm who are willing to come here.
"In the meantime, Senior Brother, you can speak with the immortals in this realm
