As the hundred-year oath of sealing spirits expires, spiritual energy revives and a great era begins. Chu Yuan, a youth from a fallen seal-guardian family, remains steadfast in his original aspiration despite poverty. For ten years, he has used his blood as nourishment, guarding the "little mud loach" that accompanied him through desperate straits. Facing oppression by fate, he has never bent his knees. When beast tides encircle the city and the people are in peril, he steps forward, awakens the Human Emperor bloodline, and awakens the slumbering true dragon. With his backbone, he shoulders the responsibility of protection, and with his hot blood, he illuminates the fireworks of the entire city. As the great era surges, the youth, bearing the mandate of the Human Emperor, embarks on the path of cultivation to protect all living beings.
