In the blink of an eye, another month had passed. Mo Wuji had failed to advance in cultivation and pill refining. The lack of immortal spiritual energy in this place rendered his cultivation futile.
Cultivating in the Undying World was a possibility, especially with the heaps of immortal crystals Mo Wuji had with him. However, there was a downside to this: the five elements were incomplete. At low levels of cultivation,the side effects of cultivating in such an environment would be minimal, whereas at high levels, doing so would interrupt the flow of his dao.
In addition to this, Mo Wuji had advanced to the level of Grand Luo Immortal in a short span of time. Even though he had not sensed any destabilisation in his fundamentals yet, it was not a bad time to take a step back and gather his thoughts instead of cultivating.
