For a moment, Lina felt her heart shudder upon seeing the dark light in Arthur's eyes that seemed like the most frightening thing she had ever seen in her life.
However, instead of being scared of him, she only became even more worried since the Arthur she knew would never have such eyes. She didn't care about the Xeton Emperor's life, but she didn't want Arthur to risk his life by trying to kill his own father.
After all, who could possibly survive after going against the strongest man in the world? It was not that she didn't believe in Arthur, but she was thinking realistically, and even if Arthur had a way to really take down his father, she felt that he might lose something important in doing so.
Even now, she was worried sick after learning that he had taken something to rapidly increase his cultivation. People die from straining their ethereal core every day, mostly due to their desperation to reach a higher level.
