Maids VS Apocalypse - Chapter 12: River of flames.

One day, I woke up only find out that I’d become a Demon Lord, an individual responsible for protecting a dungeon. The world I’d been spirited away to was one filled with violence. Gigantic monsters wandered through it and competed with each other each and every day for the right to survive. I had no choice but to strengthen my dungeon’s defenses in hopes of living another day—or at least that was what I’d thought. For some odd reason, I instead ended up spending my days in relaxation and bliss.

The dead cannot speak.

It means the living can create any story they want.

Inheritance, honor and wealth can be taken away by lies.

However, what happens when a person, who was presumed to be dead, returns alive?

[I have led a cautious life, but the system keeps trying to do me in] “Ding Dong!” “Welcome to the Smart Cultivation System!”

“You have chosen to cultivate the Bone Forging Art. The system will start cultivating for you. The system has detected that the host is missing the Bone Tempering Pill. Please wait a moment…” “Ding Dong!”

“The system successfully stole ten Bone Tempering Pills for you, and the cultivation will continue…” “Important reminder, while the system is cultivating, you will lose lose control of the body…”

After getting the Smart Cultivation System, Pei Ling began to grow stronger rapidly. He was prepared to become a deity until one day… “Ding Dong!”

“You have chosen to cultivate an unknown technique. The system has identified this as a dual cultivation method. The system will start to cultivate for you. The system has detected that the host is missing a Dao Partner. The system is looking for a Dao Partner for you…” So, Pei Ling watched as he ran to the fairy’s training room next door, drugged her, and carried her into his room…
