I Was Leveling up in the Old Days

Traveling to a parallel civilization invaded by the old days, I awakened to the online game system. Ye Feng: System, are you kidding me? Do you call these tens of meters tall monsters? What, no resurrection coins yet? System: You can find girls. Ye Feng: Okay, it's okay, activate the system! "Ding, kill the first-level tentacle monster and gain 5 experience points." "Ding, kill the third-level elite tentacle monster, gain 25 experience points, and drop equipment: tentacle monster headgear." "Ding, complete the side mission: rescue the female moaning monster." Ye Feng: Is this the girl you are talking about? Can the system return goods? Follow Brother Feng, starve for nine meals in three days, gain experience points, here I come!
