Returnee
Hao Xuan spent two full days underwater. Black would inhale a massive amount of air and leave a few air bubbles around him every few mins, leaving him to focus on breaking through.
He finally managed to expel out all of the impurities and jumped directly from Origin Realm 6 to the Pinnacle of Origin realm.
Now all he needed was to understand a new type of energy and materialize his mind palace to enter the Spirit realm.
The cultivation of this world was much different from the ones people back on earth came up with. There were no rigid limitations in most cases that said a cultivator of an Elementary realm couldn't fight someone of an Origin realm for example, one on one. Each realm had a set of specific conditions and if someone met them, they were considered to be in that realm. That's why the power level between people of the same realm often varied quite a lot.
