A Crossover, Starting with the Demon Lord's Invasion from the Crimson Realm

Endless Shennong, come forth!!!

To be honest, it's pretty far-fetched that a railgun could achieve sub-light speeds in the pitch-black environment of bullets.

No way, you wrote that ridiculous "infinite skill tree at the start" game? So it turns out he's an old Deng reincarnated as a literary youth author ☝🤓 ()

The writing style of this book is very similar to that of a certain author from Lu's previous works.

Honestly, the True Demon and Spartan bloodlines are pretty overpowered, right? Now, even stacking them up would at least put them at the level of a single character. In comparison, the only place that truly emphasizes the purity of human bloodlines is the Little Garden, and even pure humans are actually quite weak in the Little Garden, merely serving as countermeasure cards for the final trial. Even with four-digit breakthroughs, their combat power is only around the stellar level. The power of Vergil and Dante, once fully developed, is far stronger than the Cosmos and the Will of the Gods. After all, the Will of the Gods alone is far from reaching the level of a god like Chronos. The author probably doesn't fully understand how much the power levels in the Devil May Cry universe have been stacked up by the novels and spin-offs.

Are your two latest nerfs to the main character a bit too much?

A harem?

The story begins with a crisis, followed by explanations of how the protagonist is chosen as a savior of the world's destiny. The writing style and plot have a familiar feel to old-school crossover anime, making me think I'd stumbled upon an old book. I even checked the update date, and it turns out it's from 2025. It definitely has that vibe, but unfortunately, my tastes have changed, and I can't appreciate it anymore.

To the reader who has read this, could you please tell me... Is this book a harem novel?

Did the author make a mistake? Why would they assume that a name with black indicates a virus species?
