Use the Soul Fire Talisman Quickly

The power of the talisman is determined by how much spiritual power the talisman contains. However, due to limited conditions, the talisman cannot be made too large or thick, so the amount of spiritual liquid that can be stored is limited. As a result, the spiritual power contained in the talisman is limited, and its power is also limited. In his previous life, Yu Dayu was a practitioner who produced absorbent materials for "airplanes" (sanitary napkins) and diapers. He solved this problem after traveling through time. The materials in "airplanes" and diapers are more than 1,000 times more absorbent. If used to make talismans, the power would be unimaginable. So since this material can be used to make talismans, can it be used as a spiritual stone? Can it be taken as a pill to restore mana? Let's see how Yu Dayu cultivates immortality regardless of food safety! In this world of immortality after traveling through time, he often encounters things he is familiar with but cannot remember. What secrets is hidden in this world of immortality?
