Nang Nak is actually a work of fiction. It's a story created for entertainment purposes and doesn't have a basis in real events. The characters and plot are crafted to captivate the audience's imagination.
Well, without more specific information, it's hard to say precisely. Generally, a visual novel is a form of interactive fiction. 'Mana visual novel' might be about a story related to magic or spiritual energy (mana). It could involve characters on a quest, perhaps in a fantasy world, where mana plays a crucial role in the plot, like in battles or in the exploration of mysterious places.
I'm not sure specifically which 'mae nak real story' you're referring to. There could be many stories with that name. It might be a local or personal story that I'm not familiar with.
The unique power system. In a scifi mana novel, the mana - like power is often something that sets it apart. For example, it can be used in combat, for magic - like technology, or to unlock secrets. This power system creates a different kind of dynamic compared to regular scifi.
In Xianxia novels, the concept of true qi and magic power often appeared. They usually referred to a type of energy or power that could be used to cast spells or attack enemies. However, they were not equal.
True Qi was the energy accumulated by cultivators through cultivation and other means that could be used to improve the ability to cast spells. Magic power was the energy contained in spells learned through cultivation or special spell books. Thus, there was a difference between true qi and magic power.
Spirit power was also a type of energy or power that was usually used to describe a character's cultivation and potential. Spiritual power could be improved through cultivation and absorption of natural energy. It could also affect a character's appearance, ability, personality, and other aspects. In some novels, spiritual power was also used to represent a character's spiritual aura, which was the mysterious power he or she possessed.
Well, it depends on various factors. Making mana might involve complex magical concepts and systems, but writing a novel demands extensive planning, good language skills, and emotional depth. So, it's hard to say which is objectively harder.
I'm not aware of any extremely popular 'mana visual novel' specifically named just that. But there are many visual novels in the fantasy genre that involve mana - like some of the Key visual novels which often have elements of magic that could be related to the concept of mana.
In general, the idea of 'outward mana' preventing a story seems rather odd without clear definitions. If 'outward mana' is a form of energy or magic in a fictional setting, its impact on the story would be determined by the nature of the story itself. For instance, if the story is about a hero's journey to overcome various obstacles, and this 'outward mana' is something that the hero has to face and overcome, then it doesn't prevent the story but rather becomes part of it. On the other hand, if it's a random, overpowering force that stops all action and character development cold, then yes, it could prevent the story. But again, more details about this 'outward mana' are needed to give a more definite answer.
