When Xiao Lingyu saved Big Light, Big Light looked a little tired due to her old age. Her fur was sparse, and it was easy for her to shed hair.
After Xiao Lingyu bought her, she was fed with spring water every day. She now looked a lot more energetic. Although her fur was still sparse, at least, she didn't shed them often anymore.
However, Big Light was still an aged cow. Even with the spring water, she could only maintain her energy.
Similarly, Grandma Xiao and Mother Xiao drank the spring water daily too. They looked younger than before, but their actual age didn't change.
Xiao Lingyu experimented on Big Light because Big Light was not eye-catching. No one would pay attention to an old cow. Aging backward was too shocking. She had to conduct her experiment carefully.
Soon after the feast, Xiao Lingyu touched Big Light's head and could feel that Big Light's body was heating up. Xiao Lingyu asked, "Big Light, how do you feel? Does it hurt?"
