Tang Feiyang didn't sit on the bed but on the floor mat instead. In his haste, he didn't bring any food, but for the sake of cultivation, it didn't matter to him if he didn't eat or drink for days and nights.
It was a cultivation spirit. As long as he could break through in his cultivation, he would forget about hunger. If he were to eat, it would signify the end of his cultivation, so there was no need to eat here—better to eat outside.
Unlike those in the Cultivation World, they didn't consume Bigu Pills, which would make one feel as full as if they had eaten a real meal.
Even if they were to take such pills, they wouldn't be as effective as they were for the people of the Cultivation World, unless they took a Life Spirit Pill and a Spiritual Root grew inside their bodies.
Then, after that, they could purchase medicines from the Cultivation World for their practice.
