By offering the corpses of the Blood Shadows and the 15000 human soldiers, Rimuru summoned an Archdemon and his two greater demon subordinates. Using the corpses they were successfully able to materialize. He ordered them to capture the the three escaping Blood Shadows, and bring them to Ranga.

And told him to become his guardian deity. A black cocoon enveloped his body creating a perfect evolution posture.
