Plot
Darios looks at Gaster with a full face of embarrassment, and Gaster still maintains a playful and triumphant expression. He asks him, of course, that it must be a very terrifying and powerful curse, what effect does it have in stopping the magic of those mages, and if the mages are not sexually active they cannot use magic. Gaster looks at Darios as if it was the sound of the dragon's breath leaking while yawning, then smiles and explaines. He says of course has nothing to do with the magic of mages and romp (?), and if he know magic he'll understand,, um,, what should he explains... he asks he does know how magic is used. He answers yes. By the time the sun disappeared over the horizon and the spirit moon Letear appeared, most of Batran's troops had already been destroyed and the remaining troops retreated to Jakarnan Castle, so Karsel's victory was certain and these people in the highest position In the midst of their hard work, the Karsel forces are besieging Jakarnan Castle as per their strategy and preparing for the field. And these two, Gaster and Darios, who are in the highest positions in the Karsel army, are looking elsewhere on the hill where the setting sun sets. He says a person uses his magic to make his mana flow spatially and turn it into the desired shape of his contractor, and he'll give him an easy example, he asks him what happens if you build a wall where a stream flows. He replies that the water will pool. He says that it is a curse to completely block magic when the water pools and stops the flow of water, and then asks what if he throw a rock into it, even if it's not as huge an obstacle as a wall. He replies that the rock sinks. He shouts that who said a rock, it's a stream of water. He says the water will still run smoothly. He says that it should flow, but the flow changes subtly, and it doesn't matter whether the flow changes subtly or not, but if the mage's mana flow changes, it will become difficult. He says that the flow of mana has changed so that magic cannot be activated. He says it is similar, but it is not the correct answer, and it should be said that the space where the mana cast by the mage flows is not material, but a huge space in his conception, anyway, it is a much larger space than he thinks, as it is such a space, the flow of mana flows to various places, and even if a small rock is placed there to block the flow, the magic that suppresses its use is bound to be limited, but this ［Importanz Other］ that he developed is a huge net rather than a rock, a huge net woven with thin threads, it does not interfere with the flow of mana itself, but it is a magic that can interrupt the flow of all mana, and why mages don't want to become warriors even though there are magics like ［Haste］, magic to increase muscle strength, and magic to increase body vision. He says it's because he's busy learning magic and doesn't have time to take care of himself. He says of course, for that reason, mages are weak, but as he said above, he has stamina, strength, and magic that can increase everything, and he asks if he thinks it's strange because he never does hand-to-hand combat. He says he never thought about it. He explains that it is the same principle that he grants abilities by grafting curses, sub-magic, or mana, and once a curse or sub-magic is applied, the external mana must remain in the person's body to maintain the curse, so, if he cast various sub-magic, the number of spells that cause collision of flow increases, sub-magic also collides with each other, so he can't spell all of them, he can cast Haste if it is Haste, and Strength Assist Magic if it is a Strength Assist Magic, but he cannot cast two or three at once, in addition, if a mage uses such sub-magic, he will be extremely limited in his use of magic, the mages must have been quite embarrassed because the flow of mana flowed arbitrarily. He asks than if he can use any magic when under that curse. He says even if it's not just that curse, it will be difficult to use magic when it is under any curse or sub-magic, and if it doesn't collide, he can use it, but a mage who uses sub-magic on his body and works mana, doesn't exist. He says then the curse of that odd name is a First Circle blockade spell, which is pretty good. He says it is a side effect that he discovered by chance while developing it, but, if he look at it, it is a 1st Circle magic blocking spell, and the effect is the same. He asks then who will use the Seventh Circle's Absolute Magic Seal because First Circle is enough. He asks him to think about it, and says whether it is easy to remove the huge wall blocking the stream or to remove the net woven with thin threads, as easy as it is to cast a spell, of course, anyone who has mastered First Circle can unleash it quickly. He asks then if the mages were like that because they didn't even master the First Circle properly. He tells Darios that on the battlefield he seems to have forgotten that life goes back and forth in the interim between the spells, and that the spell is his own creation, once he knows the composition of mana, he can unlock it, so it will take about a minute, and that time is enough to lose his life on the battlefield. He says in any case, he killed people with strange magic, and not to say that in front of others, he tells him not to say that in front of others. As the sun goes down, Gaster and Darios move to the fortress of the Karsel army that they built around the castle from the top of the hill. He says that their soldiers have completely surrounded the castle, let them go down without making a lot of noise, and that the life of a surprise attack is speed, and advancing quickly is the less bloody way. He tells Gaster to think about what to use to break the thick gate, and the attack is his own thing to think about.
