They were well aware that if there wasn't some substance to it, the Sky Dragon True Monarch would never compromise.
In the end, the Ten Thousand Beasts True Monarch spoke up, "Let it be, let's proceed as the Sky Dragon True Monarch and that person have negotiated. That world is ultimately our prey. We've already lost four True Monarchs, we can't afford to gamble any further! Let's wait until the inter-realm passage is again passable by three True Monarchs before we speak of this!"
The other True Monarchs also agreed with this statement.
In fact, like the Sky Dragon True Monarch, having experienced the death of four True Monarchs, none of them desired to gamble with their own lives.
As long as there were no orders from the Dao Monarchs and their mother, they naturally chose the safer approach.
"Then we'll do as the Ten Thousand Beasts True Monarch suggests. The people of that world may have a trump card, but they absolutely cannot face three True Monarchs."
"Exactly!"
