Chapter 99: Flooded Soul Ocean.
The pressure became more and more intense as Haru's body slowly submerged into the ocean. The feeling alone was almost suffocating as he felt liquefied Qi all around his body.
He desperately wanted to swim toward the surface but the effects of interrupting his cultivation would be very bad. Especially since he recklessly injured himself to breakthrough. He first needed to focus on healing.
It wasn't like he had to hold his breath or anything since he was only in his soul ocean. His body on the outside kept drawing breath but the feeling of being surrounded by water was uncomfortable since the soul ocean simulation the laws of physics perfectly.
He kept still as his body carried on deeper and deeper into the abyss. Until finally the natural Qi from the beast core had run dry.
