I'm Already Max Level, and My Golden Finger Only Just Arrived?

Nan Shu survived for two whole centuries in a world overrun by monsters.

From a rookie chased by zombies nipping at his pant legs to a max-level powerhouse who could cleave open the Abyss with a single sword strike, he got by with a backbone of steel and just a tiny bit of luck.

Now the waves of mutant beasts have receded, civilization is being rebuilt from its ruins, and even the snot-nosed brat who once ran after him crying, "Big brother, help!" has become the base's commander-in-chief.

As for Nan Shu, he is sitting on a floating island at the top of the world, brewing goji berry tea.

It's time to retire.

Then a ding sounded in his mind:

[Hero Raising System successfully bound! Newbie mission issued: Go to Exit A of Dawn Metro Station and defeat the Corrupted, Heres (0/1)]

Nan Shu's hand shook, and the teapot shattered on the floor.

Not only was this damn System two hundred years late...

It was also sending him to fight a Corrupted at a place that had long since been blown into a radioactive crater?!

The System announced with great enthusiasm:

"Dear Host! Defeat the Corrupted, Heres, to unlock the main quest!"

"Your gift pack includes: Healing Bandages x3, Compressed Biscuit x1, Bottled Water x1!"

Nan Shu: "The dragon meat I've got stored in my warehouse is about to go moldy."

System: "...T^T"

Nan Shu: "And Heres, Heres... If I remember right, thanks to my amazing memory, this guy should be a Level Two Corrupted, shouldn't he?"

System: "Mm-hmm~"

Nan Shu gave a cold laugh. "Level Two Corrupted only live for ten years."
