Upon seeing the system's new notification, Lin Wu was surprised at first. But then everything clicked into place.
"No wonder I couldn't figure out what it was and neither could the system. It was being restrained by someone else." Lin Wu muttered in understanding.
He had enough understanding of the cultivation world and knew that certain exemplary figures could make their own Daos. This allowed them to dictate if others could learn the Dao or not as well.
Thus others would have to first obtain their permission before being able to even learning its name. Such were the nomological laws that could restrain one regardless of their location and strength.
"With this the Avatar should be able to reach the Dao Treading realm, but… the Main body is still—" Before Lin Wu could even finish his sentence, another memory interrupted him.
