The corpse of the half-step Great Power Yang Xing was collected into the engine room space. Li Shiming took out some blood with strange energy and mixed it with other top 4th grade corpse refining materials.
This blood was also extremely crucial. The blood was extracted from the body of the half-step Great Power Yang Xing.
After extraction, the blood could not be used directly. It needed to be transformed. According to IBMz15's analysis of multiple corpse refining bloods, IBMz15 estimated the composition of the 'Flying Night Demon' blood.
Li Shiming spent decades in the engine room space modifying this blood with a precision of 0.05 nanometers until he had blood infinitely close to the 'Flying Night Demon' blood.
In the process of corpse refining, to refine a certain level of corpse, corresponding blood must be used as a medium.
He did not have the blood of a 'Flying Night Demon', so he could only research and modify it himself.
