The novel "Coiling Dragon"

My translation of the new Western fantasy novel by Wo Chixi: The 'Dragon Blood Warrior,' one of the four legendary ultimate warriors of the continent, has not appeared for a thousand years. The only family with the bloodline of the Dragon Blood Warriors has also gradually declined, becoming an ordinary noble family in a small town. However, when Lei Lin, the eight-year-old heir of this declining family, steps into the dusty ancestral house, he unintentionally obtains a seemingly very ordinary ring - the Coiled Dragon Ring!
