In reality, this can't truly be considered a negotiation—at most, it's a division of interests. It's the division of interests among these tier-seven Professionals. Indeed, the other side has stirred up quite a mess.
The power of Star Ring here cannot afford to be overly weakened for now; they don't have the time to occupy it completely. Moreover, if their strength weakens, it would also be difficult for them to launch an offensive against the Blood-colored Empire.
Thus, this negotiation began. Du You brought his people along to participate. Star Ring indeed had more tier-seven experts, as this was the core of the world. Most people entering this world would appear in Star Ring. Including Du You, there were five top-tier forces on this side, compared to only three on the Blood-colored Empire's side.
Most importantly, relationships on his side were relatively amicable, whereas the three forces on the opposite side were less harmonious.
