"Mr. Liu's judgment was wrong; this is not a copper corpse at the Qi Refining Middle Stage!" Li Shiming assessed the situation of the copper corpse, and with the knowledge from the 'Xuanming Corpse Refining Chapter,' he was able to accurately determine the strength of the copper corpse.
The copper corpse he had subdued possessed the strength of the Qi Refining Seventh Level, far beyond the Qi Refining Middle Stage that clan leader Liu had informed him of initially.
Now that the copper corpse was subdued, he faced a problem: the gap between his strength and that of the copper corpse was too great.
Previously, he thought the copper corpse was at the Qi Refining Middle Stage, and with his strength at the Qi Refining Third Level, making a Blood Covenant and subduing it hadn't been too troublesome.
But a copper corpse at the Qi Refining Seventh Level was far too strong for him.
