There was no one she could talk to other than the Firmament Stone. She felt uneasy, and finally, she asked the Firmament Stone its opinion on whether the mussel would be killed. In fact, she subconsciously wished that the Firmament Stone would refute her, even if its explanation had loopholes. She just wanted to be comforted by words.
No matter how strong she was, sometimes she would still be vulnerable. When a person does not have desires or belongings, he or she would be fearless. However, she had something she cared about now. Although the big mussel was a big eater, she cared about it a lot.
