3 days have passed in total.
Yang Wei continued to diligently cultivate his spirit root paths.
He didn't have access to most of the spiritual Qi for his spirit root paths, so he focused mainly on cultivating water spiritual Qi. The Sapphire Crescent Talisman that he took from Jin Tianyu remained to be of good use; he could still cultivate it and push his water spirit root even higher.
Without any knowledge of how fast he was progressing, in the space of two out of the three days that had passed, he was able to push his water spirit root path from the 3rd level of Mortal Realm to 5th level.
As for his other spirit root paths, they were still very much stagnant as he hadn't devised any way to acquire those spiritual Qi types and then flourish the cultivation levels of those spirit root paths.
