After a long conversation with Old Man Han, he provided Chu Mu with a complete map.
This map almost marked the entire topography of the East Madness Forest, including the distribution of creatures. Chu Mu could use the map's instructions for step-by-step training.
The Dream of Oblivion's strength grew very rapidly, almost needing to switch locations every month because it often couldn't find matching opponents, which wasted a lot of time in the search. Old Man Han's extremely detailed drawings could save Chu Mu a great deal of time, and the Old Man even shared his many years of experience by introducing a number of Spirit Items that could help grow soul pets. Chu Mu could use these as food for the Dream of Oblivion to speed up its growth.
Chu Mu often engaged in rigorous cultivation in the past, so this long and lonely method of training wasn't too difficult for him to accept. In fact, seeing the Dream of Oblivion grow stronger every day filled Chu Mu with a sense of achievement.
