In the eyes of Qian Sanyuan and Yao Zhiyuan, as well as those high-level Pulse Refining Masters with formidable Meridian Refining Techniques, to cure this middle-aged man of his deficiency in life force and blood, the blood gu must be removed first.
After all, the man's depletion of vital energy was caused by the blood-colored gu, the chief culprit; yet, this blood-colored gu was the Gu Master's Lifebound Blood Gu, the two having long since become one. They complemented each other and could not be separated.
Should the middle-aged man die, the Lifebound Gu would also perish instantly, and with the death of the gu, the Gu Master would be drawn into death as well. Their fates were indeed intertwined, for better or for worse.
However, if they simply let the Lifebound Blood Gu devour the middle-aged man's life force and blood, the likely outcome would be the death of both, which is precisely why Yao Zhiyuan was brimming with confidence.
