At that time, Maitreya Buddha was in the Jade Void Palace listening to Heavenly King Yuan Shi's lecture; his injuries had not yet completely healed.
Plus, everyone knew that the one undergoing the Supreme Unity Tribulation at the Little Thunder Sound Temple was Great Emperor Changsheng, so naturally, they wouldn't ask Maitreya Buddha to intervene. After all, it was well-known that Great Emperor Changsheng and Maitreya Buddha were fellow disciples.
If Maitreya Buddha really stepped in, it was uncertain whose side he would take.
Now that Great Emperor Changsheng had ascended to the Supreme Unity rank, if Maitreya Buddha got involved, their cooperation would be flawless.
The Supreme Unity community group didn't even bother with angry curses of "shameless" directed at Maitreya Buddha.
The ones who survived, for the most part, were wise Supreme Unities.
Since Great Emperor Changsheng and Maitreya Buddha were willing to put on a show with them, they might as well enjoy watching it.
