Custom Made Demon King - Chapter 639 - : Let the World Burn

Yuuta was the weakest, most average guy on Earth—barely surviving college, working a part-time job, and raised in a quiet orphanage with no real family to call his own. But everything changed the night he had a vivid dream... of marrying a stunning, powerful Dragon Queen from another world.He woke up thinking it was just a dream. Until she showed up in his room—with wings, horns, and a daughter who calls him Papa.Turns out, it wasn’t a dream. And now Yuuta’s life is anything but normal.With half her power sealed, the Dragon Queen—Erza—is stuck living in the human world, adapting to cramped apartments, dishwashing shifts, and the chaos of Earth. Yuuta, once a lonely soul, suddenly finds himself with a family, a responsibility, and feelings he never knew he was capable of.As fatherhood, monsters, magical secrets, and mysterious enemies creep into his life, Yuuta must rise—not as a hero, but as a man who has something worth protecting.

It all happened so abruptly. After finally grasping my situation, I found myself in an entirely different world. Looking around, I noticed others in the same predicament… Could this possibly be one of those Hero developments?

Was there a tyrannical Demon Lord needing extermination, or would I be tossed into the maelstrom of war? Whatever it was, I was afraid. I never wanted to be a Hero. I don’t want to harm another…… Ignore the nonsense I was spouting; there was nothing to fret over.

The Demon Lord was slain a thousand years ago, and 800 years had passed since the last war. The nobles didn’t treat us summoned like tr*sh; instead, we were kindly cared for. The Demons have been on good terms with Humans for some time now. Dangers, such as monsters, were being taken care of by the Guild and the Order of Knights. What’s more surprising is the fact that I wasn’t even a hero! Instead, I was unintentionally summoned!

It also turns out that this world was a world in which the three races, the Spirit World’s Magical Races, the Celestial World’s Divine Races, and the Mortal World’s Human Races, are kind neighbors. Here, everyone lives a peaceful and fulfilling life.

In summary, this other world was――at peace.

What’s my plan for the future? For my limited stay here, I will live this world to its fullest; going on a cultural exchange, sightseeing, then, after experiencing the festival that is only held once every ten years, …… I shall safely return home.

However, despite my lust for a peaceful last year before returning, this planet’s heavyweights have begun amassing around me, and……

A recurring nightmare afflicted Khan's nights since the Second Impact. His dreams replayed the scenes of the crash of the Nak's spaceship, an alien race that the humans had defeated five hundred years ago.

Demons are lurking, and there are thousands of races.

If you don’t pay attention, you will eat the weak.

But all this seems to have nothing to do with Li Dan, because as long as he is self-disciplined, he can get corresponding rewards and become perfect and invincible!

“Congratulations to the host for insisting on exercising every day and obtaining a top-level body forging exercise.”

“Congratulations to the host for insisting on basking in the sun every day and getting a top shield.”

“Congratulations to the host for insisting on playing ball every day and obtaining the full-level alchemy talent.”

Crowd: Why does he not do his work every day, and his cultivation keeps rising?

“Ding: Release a new self-discipline task, insist on confessing the beautiful women in the sect for a month, and reward a mysterious talent.”

Li Dan: “Everyone is busy first, I have something to do, so I will leave first, senior sisters, your Dandan is here-“
