After Jacob refined all the blood, he frowned because he only got around 45% of the cursed blood from such a huge amount of blood. This clearly means that the Unique Rank blood has almost lost its effect on him, and the next time he refines the same quantity of blood, he might not get even half of it.
Even this high percentage was all because this blood belonged to myriad races, so the first time he refined it, he got a higher value.
Nonetheless, Jacob found that just as Immortika told him, nothing out of sorts happened, and he appeared to be completely fine. But just to be safe, he decided to turn this cursed blood into a longevity schema!
Jacob then quickly removed his clothing, revealing 80% of his skeleton body. Furthermore, in his empty stomach area, a glowing blue sphere filled with tiny white dots revolved like a blue star. This was his water magic core, which was revealed after his last sculpting session.
