Legend has it that there is a world invisible to human eyes between heaven and earth - the Flame Realm; the Flame Realm will elect a new leader - the Flame King - every century, and this Flame King must go through some experience in the human world. During the experience, the Five Elders of the Flame Realm - gold, wood, water, fire and earth - will successively give tests. Only by passing the test can one truly become the new Flame King...
"Does Xiaoping like Flame King?"
"Yes, I like him very much. Xiaoping wants to protect him."
"It's up to you..."
"I like you, so I want to protect you"
"You don't have to worry about my affairs."
"I have to grow up quickly and become stronger, so that I can be qualified to protect Yan."
"You little fool, what about protection? You are the one who really needs to be protected!"
"Yan, I... Did it..."
"This time, let me protect you, okay?"
