The system would issue strange missions at any time.
"Mission completed. Please select your reward.”
" Reward 1: Obtained the Overlord’s Power of the Ancestral Master Xieling, the Overlord of West Chu!”
" Reward 2: Obtain rich historical knowledge!”
Not only that, but he could also often return to the real world, so he took out some Underworld Artifacts and embarked on the path of becoming rich.
