Lan Si, who was sent flying by the Supreme Hundred-Ton King to save someone, embarked on a journey across alternate worlds. However, he discovered that he was the only one who had transmigrated into a dragon, earning the new name Acharion Verminax Pantocratol and joining a happy family of quasi-DND true dragons. Then, in this snowy land where animals had vanished, plants had frozen, and only the endless silence and cold remained, practically a forbidden zone for life, he had to live a miserable life, eating dirt every day.

But the other Lan Si had transmigrated into beautiful girls! Their plight seemed no better than his. Lan Si, who had transmigrated into Ying, was sealed away by the law of nature, but she woke up within it... Lan Si, who had transmigrated into Altria, was destined to become the doomed King of Britain. It seemed that no matter what she did, the future was unchangeable. Lan Si, who had transmigrated into a beautiful white-haired, red-eyed undead girl, was imprisoned in the Undead Asylum, with no one to give her the key? She was going to be imprisoned like this until the world was destroyed...

None of this mattered. Acharion Wilminax Pantocratol Lansi believed that with his own strength, he and the other Lansi could all live happily ever after, sleeping together in the same bed! !

Transmigrating to the world of DanMachi, Ron always felt that the dungeons he explored were different from everyone else's. From the spawn point to the boss floor, a 365-mile journey without a single rest stop; dungeon monsters setting up crossbows on narrow bridges; the despicable Sixth Brother lurking in dark corners, writhing and waiting to ambush; the indispensable treasure chest monsters of the Soul Wanderer; hidden paths... But it doesn't matter! Ron: What doesn't kill me only makes me stronger! ———Years later, the final battle descends upon Orario. Black Dragon: While out for a stroll, I encountered the world's strongest being, with stats beyond belief, as strong as a monster, whom I couldn't defeat despite my best efforts! Damn it. Who the hell raised this monster?! Dungeon: Yeah, who knows... (stabs hand)
