For the two weeks, Zion took time for himself to meditate and cultivate. There were some things he wanted to get done before he moved on to the next step of his journey, and that was preparing the path to the mystic stage.
First, within three days, Zion broke through to the Supreme Stage. With the amount of energy that raged on in his body, combined with him cultivating in a mana-rich spot, breaking through was relatively easy.
The power increase wasn't small either. Currently, as it stood, if Zion were to go all out, he would be able to survive an encounter with a Transcendant Martial Artist or Mage. Would he win? If he managed to throw them off, maybe.
However, if he fought against a Transcendant like his mother, who had his mana method, he would get absolutely bodied. This isn't including his divine relics, which could absolutely one-shot a Transendant cultivator, a normal one at least.
