After the new skill fusion, Du You didn't have many Crystal Coins left and needed to keep moving forward.
However, at this time, Du You noticed a new task on his panel.
Temporary Task: Slay Demons, slay 10,000 demons. Would you like to continue?
Upon closer inspection, Du You discovered that there was no time limit for this skill, nor was there a limit on the number of demons killed. The more demons he defeated, the better the rewards.
Thinking back, it seemed the demon-slaying count had only started when he entered the Partition Plain, otherwise, he might have achieved this figure during his mining expedition.
Du You decided not to turn in the task immediately, choosing to continue instead—it would be more beneficial as the number of demons killed increased.
"Are you ready? We're almost at the Partition Plain," he said.
