Yun bixue was truly worried about her younger sister. She was afraid that she would be unhappy and suffer.
Although Huang yize treated Bilu very well, the power behind Huang yize was as complicated as one could imagine. Bilu's personality was still rather innocent, and she was afraid that Bilu would not be able to handle some things well.
Even if the Black Dragon Gang accepted Yun Bilu, it didn't mean that she would be safe. Even though the Black Dragon Gang had already eliminated all the dangers within them, the human heart was the most complicated thing. If someone harbored any ill intentions and wanted to harm Yun Bilu, or if other international powers wanted to use Yun Bilu to deal with the Black Dragon Gang, it was possible.
Yun bixue had too many worries in her heart.
Furthermore, it was a good thing that nothing happened to Huang yize this time around. If anything had happened, the Black Dragon Gang would probably have had their own opinions.
