A strange world

Description

Sword and magic, gods and dragons, demons and abyss, humans and races.
A door appears in this fantasy and weird world, bringing in a person who doesn't belong here.
When the consciousness of two civilizations collide, what will emerge from each other?
The druid stands in front of a wheat field several meters high, and the fishmen are chasing the fish in the fishing ground;
The magic train with flashing inscriptions passed through the plains, and the sound of multiplication recitation came from the academy;
Ogryn and the children sat on the tentacles of the Son of Darkness, swinging and counting numbers;
Dwarves and elves clink glasses, and devils and priests shoulder to shoulder;
The gods chased and played in the streets, and the indescribable things around the wine table chatted happily;
The life and death of the hero and heroine in the magical image moved the devil in the bottomless abyss.
Time will eventually prove whether this person brings happiness or destruction, but before that——
He wants to learn the lingua franca of this world and not let himself starve to death on the streets.
