There were many problems that Ye tian Yun needed to take note of before starting his cultivation in the hall.
First and foremost of all was to check whether he was being spied upon or not.
After all, this hall was one of the most important places in the Gracious Sword Sect, so how could it be left unguarded, especially when a disciple is cultivating inside.
This was what worried Ye Tian Yun. If someone was indeed looking after this place, then there's no way Ye Tian Yun would try to cultivate his sword intent.
He wasn't stupid enough to reveal his trump card so soon. He would instead let go of this opportunity to cultivate sword intent in the presence of Chaos Qi.
But before making any decision, he wanted to confirm if there was really someone looking at his actions or not. And for that, he didn't need to do anything unique.
He had the system. That would be enough to clear his doubts.
