Approach

The moment Lumian saw those iron-black eyes, his mind went completely blank.

When he came to, he was shocked to find himself walking step by step toward the massive iron throne without any intention to do so.

He could feel his body trembling uncontrollably, yet he was powerless to stop his legs from moving.

It seemed as though his body was no longer his own, obeying unknown commands and directed by someone else!

This scene, coupled with the figure on the iron throne possibly being Blood Emperor Alista Tudor, instantly reminded Lumian of two past incidents:

One was at the Samaritan Women's Spring, where both he and Hela lost consciousness due to the violent reactions of the Blood Emperor's apparition, walking back to the edge of the spring as if they were puppets being manipulated or soldiers absolutely obeying orders.
