Thousands of years ago, the ancient dragon knight Ao Xuan held the "Dragon-Slaying Holy Sword" and guarded the Dragon Clan's secret realm. However, he was betrayed by his best friend and a Dragon Clan traitor. He died in the Dragon Meteor Canyon. The dragon's blood and the Holy Sword were sealed in the depths of the secret realm. Thousands of years later, Long Chen of Qinglan City, a good-for-nothing boy who became the laughingstock of his family because of his "withered sword veins," broke into a secret realm in search of the elixir to save his father, accidentally awakening the remnant soul of Ao Xuan, and was infiltrated by the dragon's blood, awakening the power of the ancient dragon's blood.
At this time, Long Chen could not even perform basic sword skills. His father was seriously injured and fell into a coma. The ancestral sword manual was also taken away by his cousin Long Chen, and he was bullied in the family. But when Ao Xuan's remnant soul merged into his body and the dragon's blood began to temper the sword's heart, everything was completely reversed!
He rebuilt the "Dragon Blood Sword Codex", and the golden dragon flame sword energy condensed on his fingertips was not only a sharp blade to crush ridicule, but also a ladder to the top. The family trial was a blockbuster, the secret treasure hunt was an exclusive opportunity, and the speed of Long Chen (Ao Xuan)'s rise made the entire Qinglan City tremble.
But the descendants of the betrayer have already laid a dragnet. They sense the breath of dragon blood and want to seize the dragon blood and the holy sword to dominate the continent. This time, Ao Xuan, with Long Chen's body, must make all enemies pay with blood, rekindle the glory of the Dragon Knight, and let the mainland hear the roar of dragons and swords again!
