"Is it the blood of the Demon Lord that helped suppress the Demon Suppression Pagoda?"
Lu Chuan's face revealed a trace of astonishment, while he simultaneously felt a secret sense of relief in his heart. He was fortunate to have the blood of the Demon Lord; otherwise, should the Great Demons within the Demon Suppression Pagoda escape, not to mention the Kunlun Domain, the entire world would likely fall into disaster.
After all, just the presence of the Nine Spirits Primordial Saint was enough to make one's liver and gallbladder split with fear, let alone the other Great Demons in the tower.
With this thought, the image of Yu Sisi emerged in his mind. If it weren't for his ex-girlfriend from a previous life giving him this drop of the Demon Lord's blood, the current situation would be uncertain. Therefore, his heart was filled with immense gratitude.
