Lin Mu's work wasn't easy and lasted a long time.
Day after day passed by while Lin Mu worked tirelessly. The only time he took a break was when he paused to observe the progress and to rectify any mistakes. But other than that, he had been working non-stop.
If it were any other formation master, they might have just collapsed from the exhaustion. Lin Mu's body cultivation they allowed him to have a stamina that would allow him to work for literally months on end.
Not to mention he was feeling really energetic after the breakthrough.
It as a form of training too, as it allowed Lin Mu to get familiar with his new cultivation base. Regular use of Immortal sense was also allowing Lin Mu to get acclimatized to Immortal Qi itself.
During this time, several other people also paid Lin Mu a visit. This included Elder Niji, Kunzi, and Immortal Taegu.
