673 From City to Fortress
The metal settled in its place as a narrow stream was carved into its surface. With a satisfied smile, Eiro looked at the last bit of work that he had completed for the circuit spanning the Monster city. Gondos, who was assisting him with the work of carving out the channels that were needed for Eiro's mana to flow through, floated around and looked at the fine and precise placement of the metal.
"Let us hope this much work was worth it," the earth spirit pointed out, "Considering how much mana you have used over the last fortnite, it has to be."
Eiro scoffed and shook his head, "Compared to how much mana I'm going to need to use to start this thing up, that much was nothing. On the days that I wasn't coming here, I was constantly pulling out the mana that was crystalizing in my chest cavity the moment it reformed. I must have collected 15 Million mana worth by now," the Demon pointed out, rubbing his chest with an annoyed expression. He sighed and pressed his finger against the metal that he was holding in his hand. There was still quite a lot leftover, since he took more just in case something was broken since he was last here. Once the circuit was up and running, the channels themselves would be a lot more durable, but right now, a lot of things could still happen to them. New novel chapters are published on
Using his magic, Eiro pulled a small nugget of steel off the ingot in his hand, throwing it over toward Gondos. The earth spirit caught it in his hands, and the stone that was covering his hands soon grew over the metal, devouring it whole, "I am still surprised you had managed to convince Armodeus to create the steel for this by hand."
The moment that the centerpiece had been saturated with this pure mana, a number of the runic sigils placed around it started to glow, and Eiro's mana was starting to be automatically distributed throughout the city into every part of the circuit. The channels were giving off a faint glow that wasn't particularly visible in the sunlight, but that also meant that nobody would be too taken aback by the circuit suddenly activating without warning.
Eiro spread out his senses, actually quickly fusing to increase his sensitivity to mana some more, and waited to make sure that the pure mana really reached every corner of the circuit. It took about an hour for it to really solidly flow through every section, but before long, it was done. Eiro smiled with satisfaction, happy to see that the circuit really worked without any issues. Or rather, that nothing had fatally broken since Eiro had started carving everything out. It took far, far too long for him to want to go back and fix something that he had already done about two weeks ago.
That being the case, this still wasn't done. Right now, it was just so that the mana had spread through every part of the circuit. Less complex circuits would simply activate the moment that this was the case, but something at this scale was practically a machine, and something with that complexity needed some guidance, at the very least in the beginning of the process. Eiro placed his palm onto one of the runic symbols at the edge of the fountain's base, activating the specific process assigned to this symbol. This one was in charge of a protective surveillance. Of course, not the kind where everyone's most minute actions were tracked, but one where harmful magics or individuals could be tracked. Things like curses or directly specified mana signatures would be tracked, and if they were sensed, it was possible to react to it a lot quicker. For this, there were some respondent lights placed into the city hall, where someone would be able to spot this with ease.
Otherwise, there were a number of protective barriers with different purposes and rules set up, some protecting the city from large-scale physical attacks, others doing the same for large-scale magical attacks. It would be possible to see large amounts of unknown mana approaching from far away, meaning that it was possible to avoid an invasion like with the Cavern Ants. Beyond this, there were some other more specific defensive matters set up. Small-scale barriers that could directly confine individuals that were tracked for certain reasons, such as for being afflicted with a curse or being violent. There were also strengthening and weakening magics put into place that would come into effect should a battle really occur here, as well as a number of pre-saved spells that could be deployed from a number of locations within the city to directly attack even heavy-hitting enemy forces.
With just this circuit, this place turned from a rundown old city, right into a fortress with defences like no other city.
