The most crucial question now laid before Zhang Heng and Bai Qing was whether they should destroy the alien tree beneath Workshop No.3 or save people first.
Judging from the information obtained by Zhang Heng, these two places were quite far apart.
Emotionally speaking, when Bai Qing learned that her mother was still alive, she wished to get there immediately to rescue her. On the other hand, she knew very well that once they saved her mother, the glass factory's aliens would be alerted. In terms of priority, the glass factory was more critical. That was because most of the aliens were gathering there, and if they were well prepared, even Zhang Heng would not be able to deal with so many at once.
If they went to the police for help, they had no way of determining if the aliens had infiltrated the force. Therefore, after hesitating for a while, Bai Qing said, "Let's act separately. You go to the glass factory, and I'll go to rescue my mother."
