The corpse of Half-Step Great Power Yang Xing was taken into the Server Room Space, and Li Shiming took out some fresh blood suffused with eerie energy and mixed it together with other Fourth Grade Top Tier Refining Corpse Materials.
This fresh blood was likewise extremely crucial. The blood had been collected from within Half-Step Great Power Yang Xing's body.
After the fresh blood was taken out, it could not be used directly; it still had to be transformed. Based on IBMz15's analysis of the blood of multiple refined corpses, IBMz15 estimated the composition of Flying Yaksha blood.
Li Shiming spent several decades in the Server Room Space, using a precision of 0.05 nanometers to continuously modify this fresh blood, and only then did he obtain the blood now infinitely close to Flying Yaksha blood.
During the process of refining a refined corpse, if one wanted to refine a refined corpse of a certain level, one had to use the corresponding refined corpse's fresh blood as a medium.
He did not have Flying Yaksha blood, so he could only research and modify it himself.
Of course, even if a Flying Yaksha existed, with his strength, he would be unable to obtain fresh blood from a Flying Yaksha.
He even suspected that if a Flying Yaksha stood right there, he still would not be able to tear through the Flying Yaksha's skin defense.
The suspected Flying Yaksha blood he had produced, after being mixed with various Fourth Grade Top Tier Refining Corpse Materials, formed a special Talisman Ink.
Finally, he added his Essence Blood to the Talisman Ink, along with a portion of Spirit Energy.
This was a method IBMz15 had developed to strengthen a refined corpse's acknowledgment of its master. After Spirit Energy was added, it was equivalent to adding
