Don't think that the young man was born poor, but the shallow water trapped the dragon. In the morning, a peacock is a tiger in the day, and in the evening, an elephant performs its night dance.
He is Matkai, a "crane tail" who is not good at ninjutsu and illusion. He was born in an ordinary life. His father is the ten thousand year genin Matai. However, in the contempt of others, he uses physical skills as a blade and youth as a fire to practice hard day and night. He has an old enemy and a close friend, Kakashi, who has a deep bond with him from youth duels to protecting the village side by side; he has a disciple, Xiao Li, who inherits his will, and passes on the Eight Sects' beliefs; he also inherits the courage of his father's death gate, shouldering the heavy responsibility of protecting Konoha with his flesh and blood.
From the dragon trapped in the shallows to the blue beast that awes the ninja world, he spent his whole life explaining: Ordinaryness is never a shackle, and persistence and fetters can eventually make the ordinary shine. Using flesh and blood as a blade, youth as fire, he finally became the blue beast of Konoha.
