Hidden Dragon: The Return of the Soldier King

He was once a sharp soldier walking on the edge of a knife, guarding the border and protecting the lights. With a body full of merits, he voluntarily shed his glory, hid in the city, and became an ordinary security guard. He intended to hide his edge and live a stable life. But there is justice in the world, and the bottom line cannot be crossed. He does not show off, does not kill indiscriminately, and does not break the law. He only uses his passion to protect the vendors' peace, the students' future, and the honest people from being bullied. He dares not forget his comrades' promises, his mother's thoughts, or the conscience of the world. The hidden dragon returns to the dust, not to escape the world, but to guard the human world's warmth.
