Angel first locked the part he wanted to analyze on the "Green Vein System" dominated by the Projected Bloodline.
Because this system is currently the most unfamiliar part of the abilities he possesses.
He planned it in three steps: first, recording the abilities; then, analyzing the operation process of the abilities; and finally, decoding the green veins.
After Angel set this goal, he knew it would definitely be a long-term study. Especially the last step of decoding the green veins, Angel knew from experience that this would take a very long time, perhaps a month, two months, even half a year, or possibly longer.
Although it's time-consuming, Angel can't avoid researching it, as it's about his own abilities. He can't be clueless when it's finally implemented.
