Once he was done with Elia's matter, Jacob continued his comprehension of the blood glyphs. At the same time, he still left Autarch to keep watch over Elia since he could tell that little girl seemed to have undergone some changes after she inherited the Liber Chaotica!
Jacob again lost track of time as he immersed himself in the blood glyphs. It took him two more decades to finally comprehend the 33rd glyph and complete the blood manipulation section.
In fact, only after thoroughly completing the blood manipulation did he realize that it was the Cursed Blood Manipulation, which was all about his cursed/infinity blood and its hidden properties.
Furthermore, he discovered that he could use blood magic to control others' blood because it was also the property of his own bloodline. The stronger his Infinity Blood, the more control he had over the other blood/bloodlines; he could even suppress or kill them!
