Insert Extraction

Even though the trace of Extraction invaded the Tekur's body without any difficulties, it was not that easy to kill them. Michael was forced to nourish the trace of Extraction slowly, ensuring that the Tekur wouldn't realize anything until it was too late. 

Therefore, Michael willed the trace of Extraction to devour minuscule portions of the Tekur's lifeforce and origin energy. Even if the Tekur felt something, since he was not injured in any way, he was likely to presume that one of his 200 enemies possessed a Soultrait with the power to drain lifeforce and energy of designated targets. He hadn't been injured nor did he sense that anything entered his body. Therefore, the option that something foreign took root inside his body didn't even cross the Tekur's mind.
