Uncle Ru, Let's Leave!
While Yi Yanlin and Yang Meiqi were fighting a cold and unknown war, Xiu Wanxue leisurely bought a lot of food and snacks along the way.
She is going to stock a lot of fresh food and snacks, even if she has everything inside her small world.
The rice field is ready to be harvested, and she could have unlimited rice to eat. So, she didn't buy the rice.
Cultivators who surpass the level of mortals and reach a certain level don't need to eat. They relied on absorbing the spiritual power to nourish and supply their bodies.
When they reach the Establishment, they can live without food for a week to a month, based on their levels. When they reach the Formation, they can live without food for a year to five years, based on their stages. Until they reach the peak of Nascent Soul, they don't have to eat.
However, most cultivators still prefer to eat and sleep, because eating and sleeping are considered to be good moments to enjoy in life.
