Time
When Jason had accessed the reward to be teleported away, he could choose any destination inside Kinra Island that cost only 10 merit points.
This was more than enough to allow him to enter the center of the Island that was quite far away.
With this knowledge, Jason could have left immediately.
However, after giving it another thought he realised that the artificial intelligence had yet to throw him out of the Inheritance site.
As such, he was not forced to leave.
It didn't mean that he had to stay either, but the cultivation energies in his surroundings were much denser than anywhere else.
Because of that, it wouldn't be bad to spend some time cultivating in the garden.
Without Jennifer around, he was too weak on his own, and his combat prowess was supposed to be much higher than it was currently.
The best for him would be to reach a level similar to someone on the Peak of the Lique stage.
