Exactly as Delicious Wind Goose had anticipated.
After displaying power last night, "Big Cousin's" people came to find them as soon as possible this morning.
The initial talks indeed went very smoothly.
After all, the management of "Big Cousin" was already quite loose and not a tightly organized group. As long as it was confirmed that they were interested, and had no intention of joining other groups, the talks were considered done.
The structure of the "Big Cousin" organization was actually loose on the outside but tight on the inside. It wasn't afraid of spies infiltrating—after all, peripheral members could hardly access any information and would end up working for nothing.
Who could become a core member was not based on their actions... but was directly determined by the "Big Brother" who was the leader. Their identities were even kept completely secret, to the extent that other external members also didn't know which among them were core members.
