While Dimitri handled the task, Noel finished his talk with the second guide, teaching him a lot about the basics of Spiritual Energy.
He was sitting on his chair, trying to write everything he had learned today.
"Hmm…" Noel looked at the notebook while furrowing his eyebrows. He tried to recall the explanation.
"Two hundred years ago, the Great Spirit Magician divided the Spirit Ability into four grades: Basic, Destruction, Annihilation, and Apocalyptic Tier.
"The Basic Tier is the Spirit Ability that only works against one to a few opponents. They are the tiers that we use most of the time.
"Then comes the second tier, the Destruction Grade Spirit Ability. When an ability reaches this grade, it will be able to destroy an area and kill more than ten people at once.
"After that, the Annihilation Grade Spirit Ability. At this point, the Spirit Ability can cause so much destruction to a town and kill more than a hundred people at once.
"When you are able to wield this ability, you should be well-known all around the kingdom. Even the Captains of the Demon Banner Army, the Tower Association's elders or all the Kingdom's Arbiters have one or two of these abilities.
"Last but not least, the Apocalyptic Grade Spirit Ability. I don't need to explain more about the destruction. It's simple… this kind of ability is simply a massacre.
"There are only two people in this kingdom who have this type of ability. The first is the commander of the Demon Banner Army, while the second person is the current Royal Knight Captain under the Royal Family."
"…" Noel looked down, recalling the power of his abilities. Due to having two spirits, he had a lot of Spirit Abilities.
However, it seemed that his level was still far away from a Captain's.
Most of his Spirit Abilities were classified as Basic Grade. Although he wasn't sure about the scale, the Undying Phoenix, the Undying Fire Feathers, as well as the Ice Vortex could be considered as a Destruction Grade.
However, he still had to upgrade them to the highest level.
Though, there was one thing that could be better than these abilities. It was his Undying Fire. This was one of the first abilities Ardagan gave him.
The Undying Fire was far more dangerous than a Destruction Grade Ability. After all, the more he upgraded this ability, the more it became inextinguishable.
He believed that once the Undying Fire reached its peak state, even a Captain from the Demon Banner Army would have a hard time extinguishing it.
Unfortunately, it was still wishful thinking to get this kind of ability. It used a lot of Skill Points just to upgrade it once more. If he poured all the points he got for a few months, he might be able to upgrade it to the final level. But it also meant the rest of his abilities would be stagnant, causing an imbalance in his fighting power.
So, he dropped that idea.
"It seems coming to this place is the right choice. I lack a lot of basics. Although I have read a lot of books in the Demon Banner Army, their knowledge isn't as complete as this place.
"But before reviewing the rest of the knowledge I had learned today, I wonder if it's possible to apply this grade to the runes."
Noel couldn't help but remember what Ardagan had told him before.
"The reason why I give you the Rune System is because you're walking on a different path from your ancestor. Your ancestor didn't wish to spread that knowledge, so only one kingdom has its official record.
"But you are going to spread that knowledge so that everyone can get stronger. I believe this is necessary for the sake of humanity."
"Hmm?" Noel frowned. "I can understand the idea. If all humans can learn the runes, it means they will be stronger to face the demons. However, I still have a few doubts regarding this decision. First of all, why did my ancestor's grandmother not spread the knowledge?"
"I think you're already aware that humans in the past didn't rely on Spiritual Energy, so there was never a need to spread it."
Noel looked down, contemplating. After seeing the technology in the academy, he knew Ardagan was telling the truth.
It seemed that the situation had changed and the need to use the runes had arrived.
"I see. I guess I didn't make a wrong decision." Noel let out a sigh of relief. He was a bit skeptical of spreading it at first, but it seemed there was a need to level up the overall strength of humanity.
After remembering that conversation, he shifted his focus back to the book.
"Well, the Spiritual Energy movement, the Spiritual Energy Reserve as well as the Spirit's Link… Luckily, those three are enough to tempt the young girl."
Noel smiled while taking out another note that contained a few names.
The Water Lord gave him these three names that he believed had switched to the other side. However, he was confused why the Poison Lord's name wasn't on the list.
After some thought, he realized that the one that poisoned the Water Lord was not the Poison Lord but the Plant Lord.
He remembered that he was once poisoned inside a brothel when he investigated a certain plant that shouldn't have gone extinct a few hundred years ago.
It seemed that the Plant Lord was the culprit.
But since this was the academic city, his focus was on the Fire Lord, one of the founders of this city. Although he didn't give an important mission to the spies, it should be enough to get some general knowledge about the Fire Lord's movement.
As for the other two elders, he was planning to use the Ardagan Family's network to deal with them.
Though, he was worried that his father's former subordinate had switched sides and would harm him the moment he reached Tamworth.
In the end, Noel spent the rest of the week sorting all the knowledge before heading to Tamworth.
