150 100,000 Magical Beasts

"24 hours of rest time and unlimited time to defeat 100,000 magical beasts…" Yuan pondered with a frown on his face. Since he can pause the challenge whenever he wants, it wouldn't affect his time in the real world unlike the Tablet of Comprehension. However, it will still take a very long time for him to kill 100,000 magical beasts, perhaps even days.

"What do I get for completing this challenge? Since you changed the original trial, I should get something in return, right?" Yuan asked the Great One.
