"Sure enough, there are strange people in every world!" Arthur flipped through the spell book, and the spells on it left him dumbfounded.

As far as he knew, in addition to the warlock bloodline contained in his bloodline, there were three classes that could use negative energy elements as a basis for magic, namely a mysterious wizard hidden in the shadows, and a necromancer who borrowed soul power and indirectly borrowed negative energy.

However, the content of this magic book is completely different, it is the product of the demon war, the entire negative elemental energy merged into the main world.

"I don't treat negative energy as a special energy, but treat it as an ordinary magic element, and activate the elemental energy contained in the main world itself with the relativity of his natural element, and also achieve the effect of general magic, this guy is crazy, but I like it!"

Arthur is sure that the guy who wrote the book is definitely not a wizard, and it has nothing to do with the wizard's inheritance, even if he only succeeded in activating the lowest level of magic in the end after his entire research, but I have to say that this is a very remarkable achievement.

If you think of magic as science, this guy is simply a buried Newton-level figure, and more importantly, this Newton, like Arthur, is still a bloodless warlock, difficult to complete meditation, and unable to reach the summoning level.

I was stunned to invent such a unique method to change the negative elements and complete the resonance with the natural elements, and successfully met the basic requirements of meditation.

The half-goblin still hadn't forgotten himself after all, and Arthur was very relieved in his heart, if he hadn't happened to run into a special event, or who knew when he would have to wait until he would actually complete his first meditation.

As an apprentice with magic power in his body, the half-goblin must have sensed Arthur's changes, and Arthur also felt a little sorry for the silent efforts of the half-goblin.

"If you have a chance to repay her again, it's a big deal to dedicate yourself, and there's nothing wrong with it." The demon king who lost his light in a certain festival is up again.

The sun rises again, the days have to go on, and Arthur's goblin capture operation must continue, and after the first two days of attempts, Arthur realizes a problem, the goblin must not be captured on a small scale, and do not expect the little greenskin to be able to carry out his orders correctly.

There is a huge brigade, a full 40 goblins, and although the grass in the farmland can never be pulled clean, it is still not a big problem to delay for a few days.

However, there was a noisy girl missing from the team, and Lilia was driven back by Arthur to meet the half-goblin, and he didn't know what he was going to give.

"Let's go straight to the violent route today, and strive to double the size of the entire team first!" Arthur was full of confidence, and with yesterday's experience, he directly divided the goblins into 4 groups.

In a group of 10, each group has an instructor-level goblin to take the lead, and today the goblins are no longer empty-handed, Arthur prepared a lot of short thick sticks for them before going out.

Although it is not possible to have every one, there are quite a few of them, and with the combat power of the goblins, it is enough to ensure the absolute superiority of the occupants on their side.

"Let's go, work, find out all the goblins separately, and bring them here, there will be no food until it's finished, and the most will be eaten at night!" Nothing boosts the morale of the goblins like a meal, and the little greenskin screams with excitement when he sees Arthur take out the sweet potato chunks, and even the original rattling sound has changed.

Arthur wasn't worried about running out of food right now, he had already asked the mayor for the first batch of rotten sweet potatoes yesterday, and if it wasn't bad, when he returned, there would be rotten sweet potatoes that could fill the warehouse, even if there were ten times more goblins would be enough for them to eat for several days.

The inventory of large landowners and small farmers like Arthur was not an order of magnitude, and lords and nobles like the Kannon had to deal not only with the rotten sweet potatoes on their land, but also with the losses caused by the purchase from yeoman farmers and farmers.

This number is so much that Arthur can't even calculate how many goblins are enough to eat for a year, which is definitely an immeasurable amount in terms of the level of mathematics education on Earth.

The goblins were all released, Arthur began to have nothing to do again, the new contract circle was ready last night, and with yesterday's lesson, Arthur did not forget to visit the cloth shop when he came back yesterday, and spent a full 5 silver coins to buy a huge piece of cloth for the noble tablecloth.

When it is spread out, it is twice as large as the summoning circle at home, and it is no problem to squeeze into ten goblins in one goblin.

Although he is always on guard against the big demons, Arthur still has a lot of trust in Aragorn's ability, let alone ten goblins, even if it is ten high demons, it is easy to summon books with the ability of demons.

While waiting, Arthur looked at the book again, the book that the half-goblin gave him, Arthur was completely fascinated by it, and Arthur had asked Teacher Dawus for this method early in the morning, and even the old wizard was amazed.

"You can try this method, no, if it works, your second space will no longer need to be reserved for the natural elements at all, it's amazing, if it works, your future magic power will be doubled, it's just incredible!" Davuls was eager to grow another body of his own and test it for himself, which showed that this method could make the great wizards of the ancient times feel magical.

Pure elemental magic is inherently more pure than mixed magic, but because of the hedging of attributes in the natural element, once you are ready to take the pure elemental route, you have to give up the function of the diversity of magic itself.

But this still makes many magicians who chase bigger and stronger embark on the path of pure elemental mages, and instead mix the elements to become alchemists and summoning mages, and even be judged as representatives of the inheritance status of mages.

Whether the magical elements are mixed or not has become the mainstream practice of distinguishing between elite mages and ordinary mages, although a few people do not agree, but the world cannot be left to him.

The conversion of natural elements is also very common, such as the school of Winter Frost, which is from the early water element mage, and then advanced to the changing ice element, the liquid state becomes solid, and the lethality of the extreme cold is also full, especially the high mountain peaks that do not melt all year round, which occupies an absolute geographical advantage.

But this is only the transformation of the elements of the same essence, in the end, the magic that turns into ice is still the water element, but it is a bit like the solid water element, and the essence is the same.

It is impossible for the water elemental magic to turn into a fire element or a wind element, especially when the purity of the magic reaches a certain level, even if it absorbs different elements and turns it into magical power, it will be squeezed out as waste.
