Lin Mu witnessed the entire series of actions that the Saintess had taken.
But it had left him a confused as to what they were.
Still Lin Mu could think and guess what it was. Looking at the 'Parasol' that was covering the area, the first thought that Lin Mu had was a protective dome of some kind. This led him to believe that this was something that the Saintess had done to protect the twins.
'But didn't she say that no Tribulation Attenuation array could weaken a Transcendent Immortal Tribulation?' Lin Mu wondered.
He watched as the Saintess lowered her hand and turn towards him.
"That should prevent others from spying on us and noticing the Twins." The Saintess spoke.
"Spying on us?" Lin Mu realized that his initial guess was indeed wrong. "What's the purpose of this 'Parasol'?" he directly asked.
