When Gu Xijiu did not come out from the door, Baili Ce and the rest were worried about her, so they tried to touch the door. As a result, they were both 'stung' and pushed back by the door. It was so painful up to the point that they wanted to chop their hands off!
At this moment, Gu Xijiu's hand were tightly grasping the door, trying to stop it from closing. With her blood flowing down from her fingers, she seemed not to feel the pain, only focused on preventing the door from closing.
The mussel and Lu Wu also came over and tried to help, however, they were pushed back as soon as they neared the door. The mussel recklessly hit the door frame so that the damage inflicted would prevent the door from closing.
Luo Zhanyu did not want to see his sister suffering, so he also ran forward to help. Nonetheless, his spiritual power was too low. So, when he reached the door, he lost all his strength and was pushed back by the door.
