The army of soul fragments alone has surrounded the feeding ground. They formed a thick sphere around it so he is utterly surrounded. It is safe to say that he won't be able to escape no matter what. He is confident enough to bet on it.
He knows that the first great mother to reach here has been here for quite some time. He got it from the memories of the soul fragment that she was only waiting for others to come. They came and surrounded this place just for him. He is the man of the hour. But he is not happy about it.
He chuckled wryly and said, "The great mother is truly talented. She took the path of parasitism and unity. I am impressed."
He found out too late that there was more than one great mother because he missed a technique called soul parasite when he acquired information from the first soul fragment he encountered. It is a technique she created to overcome the problem he faced when he reached his limit of soul grafting.
