Once he was done stabbing into his body to test River of Vigor's power, Michael returned to work. He had many things to do, including refining his Physique, Soul, and Mind. It was only apparent, but he shouldn't start slacking off only because he ascended to a Higher Lifeform. If anything, Michael should use his High Ascension to work even harder.
Unfortunately, he didn't have too much time to spare. He had to continue to cleanse the Untamed Jungle of harmful plant life. His work as the Untamed Jungle's Gardener never stopped. It wasn't too bad, though. Michael learned a lot about the surroundings, including where High Beasts had taken residence and how bad the population issue was in certain regions.
