We traveled through time together, but I'm the only dragon? The others are all beautiful girls?

Lan Si, who was created and flown by the Supreme Hundred-ton King for saving someone, embarked on a journey across different worlds. However, he found that he was the only one who traveled through time and became a dragon. He was given a new name, Acharion Wilminax Pantocratol, and joined the happy family of dnd-like true dragons. Then he lived a miserable life of eating dirt every day in this snowy field where animals were extinct, plants were frozen, and there was only endless death and cold. It was basically no different from a forbidden zone for life.
But the other Lanci have all been reborn as beautiful girls! Their plights don't seem much better than his. The Lanci who traveled back in time as Ying is sealed away by the laws of nature, yet she woke up within them... The Lanci who traveled back in time as Altria is destined to become the doomed King of Britain, seemingly unable to change her future no matter what she does. The Lanci who traveled back in time as a beautiful white-haired, red-eyed undead girl is locked up in the Undead Asylum, and no one's given her the key? She's going to be locked up like this until the end of the world...
None of this matters. Acharion Wilminax Pantocratol Blue Si believes that with his own strength, he and the other Blue Si can all live happily together in the same bed!
