The Immortal Prison: From the Start, I'm a Jailor Looking After My Sister-in-Law

Su Liansheng transmigrates into an immortal martial world overrun by demons and ravaged by war, becoming a prison guard.

When his colleague is murdered, he entrusts Su Liansheng with caring for someone he had taken in, and gives him a black pearl.

The black pearl contains a heavenly book. If Su Liansheng finds the person destined to cultivate alongside him, he can gather Dao energy, change his aptitude, and extend his lifespan.

As the saying goes: The greatest experts in the world are either in the imperial court or the imperial prison.

While searching for the right person, Su Liansheng studies all kinds of supernatural arts and forbidden techniques in the imperial prison, quietly building his strength.

He watches the seasons change, the seas turn to fields, and the world transform.

From a prison guard to a giant of the Ghost Dao, to the leader of the martial world; from a modest young woman to a wealthy widow, and then to an imperial princess…

Before he knows it, he has grown into a peerless power, commanding the imperial court with one hand and holding the martial world in check with the other.

He sleeps with beauties in his arms and wields the power of the world when he wakes.

On the surface, though, he is still just an enviable imperial prison guard with a few properties to his name.

One day, eternal night descends, and the imperial prison’s deepest secrets come to light… When a mysterious hand tries to crush Su Liansheng, it discovers that Su Lianxing has long since become all-powerful.
