After the protagonist dies, the small world begins to collapse, so the Central Bureau dispatches the rookie System 0347 to carry out a rescue mission.

The small world is now on the brink of collapse, and he needs to help the System save the canary if he wants to stay alive.

They say saving one life is better than building a seven-tier pagoda. Besides, he has no choice but to save him. He just didn't expect that, along the way, he'd go from being passive to taking the initiative...

Qin Suhui: This is exactly the job for me!
