Su Binglan only knew a few things about the Great Desolate Region. As for the exact situation, perhaps she would only know after going there. Even so, she had to go for Luo Jin'an.
She said, "You don't have to dissuade me, Father and Mother. I must go. You don't have to worry about me, okay? I'll be sure to be safe. Brother Ruozhu has many people around him, so he'll arrange for them to protect me."
Su Binglan knew her parents would be uneasy if she went alone. They also did not know about the assassins' who attacked a few days ago.
Even though she told her parents Lan Ruozhu's people would protect her, she would not bring her Shadow Guards. Instead, she planned to bring Lin Zheng with her.
She wanted to leave the Shadow Guards with Lan Ruozhu to protect him. She would only feel at ease if enough people were protecting her brother.
