"Blood Prison Dragon Path" tells the story of the counterattack of Ling Yun, the eldest son of the Ling family of the Tianfeng Kingdom. He was born with a "vein-locked body", and his meridians were blocked and he could not practice cultivation. The strange blood-red birthmark on his chest made him regarded as a "disaster". He had been scorned and tortured by his family since he was a child, and was even judged to cause catastrophe.
On the verge of death, the secret of the ancient "Blood Hell Dragon Mark" in the birthmark is unexpectedly revealed, and the forbidden dragon power sealed in it suddenly awakens - this power that combines the magical power of the dragon clan and the sea of netherworld, can devour the cultivation of others and turn it into one's own use, but it also carries a curse that erodes human nature. After awakening, Ling Yun has to fight against the pursuit of his family who regard him as a scourge, and resist the various forces in the Nine Realms that covet dragon power. He also has to struggle between the temptation of power and the persistence of human nature.
As the power of the dragon grows stronger, Ling Yun gradually discovers that the "seal" guarded by the family for generations hides the secret of the ancient dragon clan being framed, and his life experience is closely connected with the contract of the three realms and the shocking conspiracy in the land of exile in the sea of blood. With the flames of revenge and the pursuit of the truth, he walked through the mountains of corpses and seas of blood, and moved forward step by step amid the pursuit of dragon hunters and the bewitchment of the blood prison fantasy. He would eventually uncover the ultimate secret behind his bloodline and find his own path to a dragon that defies the heavens.
