Douluo Auxiliary Upgrade System

Transmigrating to the Douluo World, at the beginning of the storyline, Lin Feng awakened the auxiliary upgrade system.
As long as he did something that could increase his strength, he would be able to gain experience points!
Even a jog or a nap could increase his experience points!
[Ding! I had a nightmare when I was sleeping. I dreamed that I became a Soul Master who had cultivated for two and a half years. My Spiritual Power has increased slightly. Experience Points + 100]
[Ding! After a period of hard work, the host has mastered the Basic Axe Technique. Experience Points + 100]
......
Looking at his experience bar, Lin Feng knew that he would create his own legend on the Douluo Continent!
