Ye Xuan activated the system for modifying the production dates of all things, which brought about earth-shaking changes in his life as a waste collector.

[Ding, the broken fruit phone is modified to the day it was manufactured]

"I saved some money on buying a mobile phone."

[Ding! The bronze artifacts from the Shang and Zhou dynasties were changed to three days ago]

"I'm sorry, this bronze ware of yours is not from the Shang or Zhou dynasty, but from last week. I can only give you thirty yuan at most."

[Ding! This year's blue and white porcelain bowl was changed to be produced 500 years ago]

"It can be used as a bowl for the dog at home..."

[Useless Start] + [Data Flow] + [Playing Dumb to Snag a Strong Player] + [Conceptual-Level Cheat]

In the year 2024 of the Blue Star Calendar, the entire population awakens. Lin Guang, a transmigrator, attracts much attention due to his outstanding looks, but during the ceremony, he awakens the universally acknowledged most useless F-level ability—[Data Insight]—becoming the laughingstock of the entire school.

However, only Lin Guang knew that in his eyes, the world was not just data, but also code that could be edited at will!

The stones on the roadside are too hard? Change the hardness to 0!

The school bully is too arrogant? I'll modify your belt's durability to 0, and make him die on the spot!

From modifying item attributes to altering the laws of physics, Lin Guang appears to everyone as a useless support character, but in reality, he is the sole backend administrator.

When the Outer God descended, and the S-rank powerhouse was in despair, Lin Guang silently chose the Demon God's health bar:

[Health Points: ???] -> Change to [1]

"Sorry, your presence was invalid and you have been deleted by the administrator."

This is the story of a "useless" guy who uses a bug to modify the world and ultimately achieves physical salvation.
