It seemed like the old man named Ander had nothing to fear.
Angele’s pouch and his extraction method were not what Ander was going after.
Without the chip, Angele would not be able to extract the ancient blood just by himself. Other wizards had already spent hundreds of years in trying to discover a method that had a high success rate. And even if they managed to find one, they would keep it as a top secret. Extracting the ancient blood was one thing, but creating the signet was completely different. Ander was trying to take everything away from Angele.
He himself knew that if he could get the signet, he would not need to extract the ancient blood by himself.
Furthermore, without the signet, Angele could not backstab him with the illusions. He knew how difficult it was to prepare for a strike from the mysterious signet.
