Elder Jiu was a busy man so he could not chaperone Chen Xiaobei all the way. On top of that, he wanted to get home to his family as soon as possible to give them a detailed account of his association with Chen Xiaobei.
So, the two men parted ways.
After the old man left, Chen Xiaobei boarded Fang Zi'er's yacht.
Wrath Wave Faction was no longer any of his concern. Now that Hu Bawan was dead, the faction's minions would scatter like roaches in the sewer.
The core members would have to deal with possible internal conflict in the fight for leadership. From now on, they would no longer be a threat of any kind to Tidal Faction.
Eliminating this menace meant that Lin Xiang could continue to train peacefully without any interference.
