The egos of the Empera's were focused on watching the drum show that was taking place in Zhao Luo's mind.
They were rather enjoying it as when will they get the chance to enjoy times like these anymore.
In Zhao Luo's dark space.
The second apparition was standing in front of the first drum.
He started beating it as hard as he could.
This apparition had two goals in his mind.
First, he wanted to beat the record of the other apparition.
Second, he wanted to beat the drum hard enough such that it produces so many echoes that the other apparitions after him don't beat his record.
Thus he started beating the drum with all his might.
Unfortunately for him, he couldn't surpass the record of the last apparition as every time he beat the drum, the sound of the 'boom' would echo as many times as it did when the apparition before him would beat the drum.
'Heh, good. Keep on doing your best.'
