Chu Yan clutched the hot fire pattern sword and watched as Su Qingyuan was wrapped around the neck by the rotten bone evil poison. The remaining fire spirit roots in the Dantian were severely burned by the rapid fire attacking the heart. In order to find the "Bing Xin Jade Dew" to save the master, the two of them unexpectedly bumped into the evil bone cultivator in the late stage of foundation building in the Netherworld Valley.
The Bone Master swung the bone whip covered with corpse spots, and the black evil poison spread like a spider web: "How dare a mere Qi refining monk invade my territory? This girl's wood spirit root is just the right time to refine my poison pill, so you can use it as nourishment!"
Su Qingyuan endured the severe pain of poison erosion and slapped the last vitality talisman on Chu Yan: "Chu Yan! Leave me alone, the ice heart jade is exposed at the bottom of the cold pool, use your spiritual fire to force out the evil poison!"
Determination flashed in Chu Yan's eyes, and the broken fire spirit root suddenly resonated with the spiritual light at the bottom of the pool, bursting out a golden and red "evil-burning spirit fire". The moment the sword light split the evil poison, he actually saw through the trajectory of the poisonous veins - it turned out that to destroy the fire spirit roots, you need to borrow the power of the evil poison to advance, but Su Qingyuan's wood spirit roots can symbiotically transform into vitality.
When Chu Yan used advanced spiritual fire to purify the source of the poison, ancient runes appeared in the depths of the cold pool, and a black jade engraved with "Inheritance of the Poison Ancestor" rolled down from the Bone Lord's body. A greater evil poison crisis was quietly awakening.
