Firstly, he was a little bit astonished by the fact that he could circulate the energy of the Soa crystal through his body as if it was his routine.
However, what he perceived when he led the energy towards his soul world core was even more exciting!
Continuing to experiment, he lead the trace of energy towards his soul world because his gut feeling was telling him that this was the correct move.
In the end, this was dangerous, but his gut feeling had never betrayed him so far.
With that in mind, Jason circulated the Soa crystal's energy inside his soul world, where the soul world core was already vibrating brightly.
Only a fraction of a second later, the soul world core took the reins of control away from Jason and suctioned the Soa crystal's energy inside.
This astonished him a little bit, only to notice that his passive soul energy increment circle had been accelerated.
