I Guarded the Immortal Realm’s Black Prison for Three Hundred Years

Yan Qishuang ascended from the cultivation world to the Immortal Realm. Widely acknowledged as the greatest martial cultivator, she was also the strongest in immortal arts.

After some discussion, the higher-ups assigned her a job no immortal had dared take in a hundred years: guarding the Black Prison.

At first, Yan Qishuang wasn't exactly thrilled, but the monthly salary in spirit stones was generous, so she figured she might as well give it a try.

Then the immortals of the Immortal Realm gradually discovered that:

The primordial ferocious beast that couldn't be restrained by seven soul-locking chains had become as tame as a cat not long after arriving at the Black Prison, and willingly became Yan Qishuang's spirit pet.

The evil cultivators and rogue immortals imprisoned in the Black Prison offered all their divine artifacts to Yan Qishuang, claiming they were now underling followers of Boss Yan.

The Third Prince of the Immortal Realm, locked up in the Black Prison for three months, was thoroughly disciplined by Yan Qishuang. Word was, she broke his legs, and not just once. After he got out, even hearing the character Qi made him tremble all over.

Yan Qishuang's take: Nothing special, I just hit hard.
