"Yes, that's why the cultivation world has such a clear hierarchy. This is a very important reason."
The system also stated.
"When you first enter the Qi Refining Qi Refining Stage, many materials, spiritual plants, and pills, even if placed in front of you, you would only think they are poisonous, and would never think that these things are meant to be eaten."
"Some materials used in the Golden Core Stage even carry enough Fallout to kill an ordinary Qi Refining Stage cultivator. Let alone ordinary people, how many layers of Fallout clothing would they need to wear to get close enough to observe them, and even then, they could only observe from a distance, not handle them up close."
Speaking of Fallout, Li Xingkong couldn't help but think of the Mushroom Egg, the most powerful weapon known to humankind.
Thinking about it now, Li Xingkong that this thing was probably a pill or elixir used to aid cultivation Golden Core Stage. He couldn't help but pat his stomach.
"Hiss~" His imagination was really limited; what kind of person would actually eat this stuff like a elixir?
"Therefore, besides Qi Refining Technique, the most important spell in immortal cultivation is the next one: the Ingestion Spell."
The system directly provided the spell's name; it was simple and unpretentious to a certain extent, possessing a rustic beauty.
What kind of "cooking technique" is this? Is this some kind of magical invention by a foodie?
As the system mentioned the Ingestion Spell, Li Xingkong couldn't help but think back to when he first started Qi Refining, the system had mentioned many miscellaneous techniques when he was asked to choose Qi Refining Technique, such as the Qi Refining Technique absorbing various types of energy.
The foundation of these Qi Refining Technique may lie in the Ingestion Spell.
In fact, Li Xingkong's guess was correct. The origins of the Ingestion Spell and the Qi Refining Technique were basically the same, both being explored in the early stages of the cultivation civilization. Both of these techniques were excellent Qi Refining Techniques, but unfortunately, the Qi Refining Technique eventually became the mainstream.
The main reason is simple: Qi Refining Technique is truly suitable for large-scale practice. No matter how many people there are, they can never exhaust the energy they gather from the sun and moon; it's a renewable energy source.
But the Ingestion Spell is different; the things it consumes are real, non-renewable resources.
It's enough for one person, but it's also barely enough for a group of people.
If everyone in the world were to eat together, they would all starve to death within a few years.
There simply aren't enough resources.
However, it seems there's no way around it now; everyone has to learn it eventually. On the path of cultivation, who can avoid taking drugs?
Looking at other stories now, it's quite funny that the protagonist is completely transformed after obtaining a high-level precious medicine.
If I were to hit a piece of radioactive material right now, I would truly undergo a complete transformation, and I would be one year old next year.
"Come on, let's get started!"
Li Xingkong adjusted his mindset and prepared to receive the spell.
The system flashed, and Li Xingkong felt something being injected into his brain—a huge chunk of knowledge.
Unlike the previous minor Shotgun Spell, this time it's going to completely cripple him.
Judging from the sheer amount of knowledge involved, Li Xingkong already knew that this thing was exceptionally difficult.
After all, Shotgun Spell only requires a simple Magic Power structure, while Ingestion Spell requires working on the entire digestive system.
The level of complexity is naturally incomparable.
Just like when he was overeating, Li Xingkong needed to digest his food while he was still on the spot.
After he had sorted through the extra knowledge in his mind, he finally had a general understanding of the entire Ingestion Spell.
Ingestion begins with the mouth. To develop strong teeth, one must first build a complete Magic Power structure within their mouth, strengthening their teeth, tongue, and oral cavity. Regardless of the material or other properties, you must be able to swallow it before proceeding with the next steps.
It is often said in ancient times that Sage has 40 teeth. This saying actually corresponds to what Li Xingkong learned about the Ingestion Spell. The extra teeth just happen to meet the Magic Power nodes required by the Ingestion Spell on the teeth. There are 40 in total. When they are planted on the teeth, they form a complete spell that can strengthen the teeth and help to chew the materials in the Qi Refining Realm.
Given Li Xingkong's current strength, if he completes the Magic Power nodes on his teeth, then the so-called grilled steel sausages he saw on Bilibili would truly be food for him.
Forget about eating iron, you could even bite into steel.
It's a pity he won't be able to gnaw on bones anymore. He won't feel it anymore, he won't get that kick of gnawing on bones. Bones will just taste like soda crackers to him, with no crunch at all.
After the mouth, it's the esophagus and stomach. This entire Ingestion Spell must cover this area, treating the stomach like an alchemy furnace to refine the ingested materials and convert them into components that can be absorbed.
This is the major part of the Ingestion Spell. Different materials have different digestion methods. If you want to be able to eat anything, then your Ingestion Spell need to be improved to a certain level, and you need to master them.
For Li Xingkong, he doesn't need to train to such an advanced level right now. He needs to eat a very simple diet, just one spiritual plant to help Bone Tempering. He doesn't need to build up his entire body; he just needs to make sure he can digest the spiritual plant.
So what seems like a lot of trouble is actually only a small part of what he needs to do.
Then there's the absorption of the components after digestion, which, according to the Ingestion Spell, is achieved with the assistance of Spiritual Qi.
That's why Spiritual Qi is essential for cultivation. It's incredibly important, acting as eyes, architect, and transporter. Without it, one cannot manipulate the microscopic world at all.
Unfortunately, he'll have to wait until he reaches the Foundation Establishment to refine his own Spiritual Qi.
Otherwise, it would save a lot of trouble.
Having read through the entire outline of the Ingestion Spell, Li Xingkong didn't linger. He quickly finished his work, stopped looking at the crop, and since it had already grown into a sapling, he decided to let it grow on its own for a few days.
The most important thing now is to figure out the Ingestion Spell.
It can only be said that Li Xingkong's cultivation over the past few days has indeed been effective. The construction of his Mana Circuit has begun to show results. At least when he starts learning the Ingestion Spell, he no longer needs to open Mana Circuit separately, as there are already pre-built circuits available for him to use.
That's why the orthodox schools of Daoism emphasize a solid foundation when training their disciples. If you have a solid foundation, you can achieve twice the result with half the effort no matter what kind of magic you learn. But if your foundation is weak and your basic skills are terrible, even if you are given a magic spell, you won't be able to get the hang of it for a while.
This time, Li Xingkong gained the benefit of a solid foundation from learning the Ingestion Spell; he was able to build up the Magic Power structure in his teeth quite quickly.
Firstly, I already had some understanding of Shotgun Spell before. Secondly, I benefited from the Explosive Counter Spell. This spell requires charging and constructing a spiritual energy structure each time, which provides a lot of practice opportunities for building Magic Power nodes.
Having already gained some familiarity, practicing now will naturally be much faster.
