Yu Huang was a cultivator, so logically speaking, she shouldn't feel cold.
Sheng Xiao was worried that there was something wrong with Yu Huang's body, so despite seeing that Yu Huang was exhausted, he woke her up. "Wake up." After Sheng Xiao called out to Yu Huang a few times, Yu Huang moaned a few times but fell asleep quickly.
Sheng Xiao had no choice but to kiss Yu Huang to prevent her from breathing.
About a minute later, Yu Huang felt suffocated, so she opened her eyes and push Sheng Xiao away. "Brother Xiao, what are you doing?!" Yu Huang sat up and took a few deep breaths. Then, she covered herself with the blanket.
Sheng Xiao frowned and asked with concern, "Are you feeling unwell? You're so cold."
"I'm not feeling well," Yu Huang said. "I feel as if there's ice hidden in my body. Even my bones feel cold." Yu Huang rubbed her arms and asked Sheng Xiao, "What temperature is it now?"
