This great demon was likely a tiger flood dragon. Its body was enormous, with little fur on it; most of it was covered in scales.
If this great demon had still been alive, even if they attacked it, they would have been unable to break through its defenses. But it had been dead for nearly ten years. Its qi and blood had withered, and its physical defenses had naturally weakened many times over. Breaking through them was no problem.
Li Changsheng walked over. Qin Xun handed him an eighth-grade longsword and had him cut through the tiger flood dragon's hide and flesh to extract its demon tendons.
Standing before the tiger flood dragon's corpse, Li Changsheng swung the longsword again and again. With every strike, Demonic Nature erupted and spread toward him.
Qin Xun could not withstand the great demon's Demonic Nature aura and immediately retreated. Li Changsheng, meanwhile, activated the Vajra Dao Fruit to refine that Demonic Nature, which also raised the Vajra Dao Fruit's experience slightly.
Li Changsheng hacked away for a full shichen before finally cutting through its hide and flesh. He found a section of demon tendon and sliced it off.
Then, using the Demon Extraction Art, he extracted the Demonic Nature contained within the demon tendon. Only then was it a demon tendon suitable for a martial artist to refine.
"Senior Brother, this demon tendon is for you," Li Changsheng said.
"Thank you, Junior Brother Li." Qin Xun was thrilled. The demon tendon he had dreamed of finally lay in his hands, and it was even the demon tendon of a great demon. It could absolutely help him cultivate to the Flood Dragon Tendon Realm.
"Senior Brother, I'll continue cutting apart this tiger flood dragon's corpse and extract the remaining demon tendons."
