Comments of chapter undefined of Killing Cockroaches In Xianxia For Self-Preservation

Honestly Qi could probably replace food, but I doubt there is anything wrong with normal nutrients. It is after all energy that has to do with life which is probably why it can extend lifespan because they're absorbing life energy from the environment and plants. Though things like protein could probably increase the foundation as the body would be nourished with the actual vitamins and minerals instead of what is basically a natural supplement.
