When all the members serving seven deadly sins finally came to terms with their predicament and decided to follow Zeus and his claims for the future, the celebration continued for the whole night.
Not everyone had believed his claims and still had misgivings left in their hearts but no one could do anything as all of them were already marked as slaves after the blood-oath token ritual and they could no longer try to exact any form of revenge.
Even plotting against Zeus & the Sins would mean their inevitable death, so all they could do was nod their heads and pretend that they believed his words.
Even Kahn knew that actions spoke louder than words so he knew that it will take some time until his claims became reality.
Zeus then explained his plans to expand their networks and even get other underworld organizations such as battle arenas where a betting system was allowed and assassins organizations under their control.
