At this moment, Heavenly King Yuan Shi choosing not to make a move is in itself a form of assistance to him.
Behind Hao Tian is the support of the Cultivation Path Ancestor; should the Three Purities really take action, the consequences might well become uncontrollable.
Most importantly, it's not certain that Hao Tian will succeed.
Therefore, the Three Purities manage to stay put.
Hao Tian also knows that the Three Purities are unlikely to intervene, but he still needs to show his respect to the Two Purities.
Yes, the Two Purities.
He did not visit the Green Jade Palace.
Buddha Tathagata has already made his move.
Heaven Connecting Sect Hierarch has been grounded.
So he won't waste his time.
After all, the Heaven Connecting Sect Hierarch would neither intervene nor would he give up his support for Buddha Tathagata to back him instead.
If he has the time, he might as well visit Empress Nuwa's Palace.
