Gu Xijiu was certainly relieved that they were all alive.
However, the boy was not doing quite well. His body was already half-frozen.
Gu Xijiu quickly teleported next to her son. She then placed her hand on his legs to transfer a steady stream of heat into the frozen lower-half of his body to melt away the ice.
After a while, Di Hao was able to move his arms and legs a bit. "Mother, you are able to move again," he said excitedly while tugging her sleeves.
When the lady in white first approached Gu Xijiu, she looked like she was getting possessed. A layer of ice appeared and disappeared from her body from time to time. However, she had no consciousness. Her eyes remained shut all the time.
Anxiously, Di Hao rushed forward to help, but before he could even get close, half of his body became frozen.
Luckily, he realized in time that danger was real, so he started performing a spell to keep avoid being turned into an ice sculpture.
