The Delivery Boy Inherits the Heaven System and Is Sent to Hell

I, a social worker who delivers food, inherited a heavenly food delivery system. Others rely on meditation to achieve immortality, but I rely on on-time delivery to achieve immortality. The first order: The eighteenth level of hell, opened by the king of hell. One second overtime and the soul is gone. The system told me: This is the final test. I was given the chance to become a Daluo Jinxian in seconds, but it was a failure. I started working in the underworld for three thousand years.
