They seemed to disguise themselves to blend with the people around. Why did they need to hide their presence from everyone? Was Yu Qi in danger? He wanted to ask Yu Qi but seeing her attitude toward him, she would not tell him anything.
Bai Shu Jin also wanted to go to FINN City. He would try to find a chance to talk to Yu Qi. Actually, the reason he would need to go to FINN City was that he needed to go to Tang Private Hospital to seek help for his brother.
After Bai Jian made a mess suing Yu Qi, the Tang Private Hospital discharged Bai Yu. Bai Yu was still in a coma. Even though Bai Yu was his half-brother, he loved Bai Yu. He wanted Bai Yu to get better. He was willing to apologise to Tang Private Hospital for the sake of his half-brother.
So, Bai Shu Jin would see Yu Qi again. Seeing Long Hui was not around, he knew Long Hui was probably busy with his soldiers' work. He would keep trying to approach Yu Qi.
