Xia Xing is the only three Muggles in the family (the first two are his father - Dead Ye and his eldest brother - Xia Yu) and the youngest child in the family.
He is obviously a domineering and willful "naughty child", but he is loved by all. Because she has the coquettish and willful essence of her sister Xia Mei, the honest and cute face of her younger brother Xia Tian, and the smart and shrewd mind of her elder brother Xia Yu.
And the family's skills are not what Muggles can fight, so even a Muggle has learned the violent factor of certain people (ghost dragons) over the years, and it is more than enough to deal with a Muggle.
Age settings: Xia Yu (20 years old), Xia Tian (18 years old), Xia Mei (16 years old)
Xia Xingxing (14 years old)
The protagonist is a middle school student who is in the third grade of junior high school. He is quite a "naughty kid" and has no emotional line. Generally, the main plot remains the same and he does not know the plot. The protagonist is not a real Muggle, just like Xia Yu.
Concept: The original idea was based on the TV series I watched when I was a kid.
