Fang Zhen didn't spend any merit points to unlock it.
He had entered the Crystal Bone Realm mainly for a vehicle and to obtain items that would improve his endurance.
Now that he had both, there was no need to delve any deeper into the Crystal Bone Realm.
In fact, even without spending the merit points, Fang Zhen had a general idea of what the instance after the Land of Rest would entail.
Avera, Connor, and the others were already the Crystal Bone Realm's top-tier fighters. If there were subsequent instances, he guessed they would go in one of two directions.
The first would be the escalating conflict between the Thirteen Families and the barbarians. Fang Zhen would have to choose a side—either helping the barbarians or one of the families. From the look of things, siding with the barbarians seemed more likely, which would make the Patriarchs of the Thirteen Families his opponents.
The other direction would involve the Netherworld, represented by the Gatekeeper.
