Invincible Starting with the Cells of the Dark Lord

I solemnly declare that this is definitely not the scum that fell from my body, because the scum that fell from me can be assimilated and engulfed the world in up to three days. I still want to collect more energy, otherwise it would not stretch my hips so much.

In the past, DC's Doomsday practiced Wing Chun and Snake practiced fighting. This novel has Star Cat and Dark Lord practicing breathing techniques! Damn it, are you, the authors, humans and machines?

There are always those protagonists who are invincible, but still have to join the Demon Slayer Corps or cooperate with the Demon Slayer Corps. They serve as a Japanese dog as a subordinate and call him Lord. If you don't even recognize him, you can call him Lord. In ancient times, calling you like this is equivalent to treating yourself as his subordinate and slave. Most of them are the kind of die-hard dogs.

After reading the introduction, I felt like I was sitting at the same table as Doomsday playing Wing Chun🤣

The first world: Demon Slayer: Kimetsu no Yaiba The humor in the introduction suddenly came up🤗🤗

Why would you join a demon slaying team if you have the power of the Dark Lord? Absorb negative energy, create little black monsters to possess pillars and ghosts, seize control of Wuhan, and restore a certain amount of energy to create wind, fire, water, and earth demons. These four demons can also create dependents, whether humans or ghosts, it is no different for the Dark Lord, and finally devour the world.

6. With the Dark Lord's ability, even if it's just a fragment, he still recognizes someone in Demon Slayer as his master? The Dark Lord said that he was not that lazy. He originally thought that those useless little black monsters were already useless, but he did not expect that among the useless, there were also useless hands. If the twelve constellations warriors and the powerful cat Star Cat were like this, I would have completely ruled the universe long ago.

After the original Dark Lord was resurrected by the Star Cat, he absorbed the evil power on the Celestial Planet and restored himself. The clone made trouble on the Celestial Planet and almost destroyed the Celestial Planet. Later, he regained his original posture and was driven into a black hole. After that, he was strengthened and then was driven into a black hole again. This is outrageous stuff. The protagonist you set as a cheat is the Dark Lord. Humans in the Kimetsu no Yaiba world are not gods and fairies who have the power to deal with the Dark Lord. Absorbing the evil power and recovering should be faster than the clone on the Celestial Star. But instead of absorbing the evil power and recovering quickly, you, the protagonist, learn the breathing method that is useless against the Dark Lord to kill ghosts. What is the difference between this horse riding and Wing Chun on Destruction Day?

What the hell? Everyone who has the ability has to go to the Demon Slayer Squad. If you leave the original plot, you can't continue writing, right?

No, Demon Slayer has been around for several years, why do people keep writing about it? I've watched the anime, but the fandom really can't read it. The original plot is basically a history of resistance struggle, so adding a new protagonist would be boring. There are not many good things, just a ghost king and sword skills. The ghost king has absolute leadership and complete control over the ghosts. The sword skill settings are basically special effects, and the normal upper limit is about the same as bullet time. There is no good conflict in the plot. It is basically just plot + secondary abilities, which is really boring. Not as attractive as the Dragon King's son-in-law.
