After Jason had spent some time with Jennifer and looked after her needs and comfort, he was ready to leave and be in isolated cultivation.
There was no need for him to use any cultivation resources inside the Divine Heaven, and it would be more than enough for him to use the surrounding energies.
The mana and divine energy that permeated the Divine Heaven was more than enough for Jason to cultivate with the highest efficiency, for centuries or even millennia.
As such, he was just about to leave Jennifer's side in order to create his Shell of Immortality, when Yaldra returned to his palace.
His eyes widened upon perceiving Jason's presence which was far more terrifying than any kind of existence at his stage could have.
Clearly understanding that Jason was capable of fighting Primordials at the Yimal stage, while still being at the Initial ranks of the Driekta stage, made him stare at his son with awe and the slightest tinge of fear.
