Turen and the other elders' mouths twitched as they listened to Havek's words.
"Light Formation? We already have Light Beads, so what's the use of your own?"
Havek nodded as he replied.
"Indeed, we do have Light Beads. However, they are still Spiritual Tools, quite expensive ones at that. After all, not only is there a need for a tiny Energy Gathering Formation inside them, it has to be double-layered with a Light Formation as well. Nowadays, most people would definitely prefer torches instead."
"However, what we have here is a Light Formation that works with the Communication System's so-called electricity."
Havek then pointed at the several cables spread in various directions. At the end of each cable, there was a blue stone that looked like a bead as well.
"You should be able to tell that those are simple lightning glass beads, right? They are quite simple to make since they only need the sand of areas with big amounts of Lightning Element. They will light up with any amount of electricity poured into them, naturally. Of course, the more you put into them, the brighter it gets up to a certain limit."
"During the time I was researching the new Communication System's blueprints, I happened to be using these beads for something else. The Communication System's electricity is nothing more than small pulses of Lightning."
"However, it was only today that a thought regarding a very practical method of generating light with almost no consumption of Spiritual Energy had popped up. In fact, it uses just a tenth of the amount of Spiritual Energy to generate the same amount of light as Light Beads. The main difference is this coated wire. It prevents the Lightning Currents from disappearing, so it can be spread over great distances."
Havek then turned his Light Formation on. The copper cables immediately transferred the electricity to the lightning glass beads, which lit them up straight away. Just as Havek mentioned, they all showed the same brightness as the Light Beads that they knew.
"I have to thank Senior Droman for this finding. His Communication System's energy controlling structure is just marvelous. With that, my Light Formation can control each of the electrical cables' output so that the lightning glass beads won't burst with too much power."
Havek continued with his passionate speech.
"What you are seeing here are more than 50 lightning glass beads being powered by a single Light Formation. This Light Formation is not using even a single spirit stone, only the surrounding Spiritual Energy. If you take 50 Light Beads, it will be impossible to light them together with just this paltry amount of Spiritual Energy."
"You don't need to tell me the downside of these formations. It's a given that it'll be the cables. Light Beads don't need any cables at all. There would definitely be places where it would be better to have Light Beads instead of my wired light."
"Nonetheless, that isn't the case for the majority. Having some copper cables lying around is a low price to pay for the amount of Spiritual Energy you can save. Not only that, you could literally use this kind of system to light up the entire capital's houses. For the city as a whole, this formation would be of unprecedented versatility."
Turin and the others were really impressed with Havek's invention. It was simple; no one doubted that. However, the uses of such a thing were unlimited. For example, the capital's Protection Formation used a large amount of Spiritual Energy to run. If all houses that had Light Beads were swapped with the Electrical Light Formation, a lot of this saved Spiritual Energy would be redirected there.
One might think that the amount saved wasn't nearly enough to power up the capital's Protection Formation. However, this was a permanent solution. Just how many spirit stones would be saved in an entire day? In a week? In a month?! In a year?!
"Marvelous! Simply the most practical formation we have seen so far! It's simple but effective. Literally everyone, rich or poor, cultivator or ordinary people, can use it."
Saya also nodded, incredibly satisfied.
"Havek, right? You are not bad yourself."
Havek looked at them as if he already expected this kind of reaction.
"Hahaha! Obviously. This god here is nothing else but amazing."
Rean looked from afar and couldn't help but praise Havek as well. Such an invention back on Earth wouldn't be considered groundbreaking. However, Havek didn't know of Earth. He had never seen the electrical features there. Nevertheless, he came up with this solution on his own.
'He's the cultivation world's Thomas Edison. Well, it's not a light bulb, but it's similar. I don't think Edison was that narcissistic either.'
As always, the examinators pointed out what they thought was wrong with the formation. However, anyone could tell that they still thought that this invention could be used straight away. Also, they had spent more time speaking with Havek than any other cultivator so far.
Eventually, they finished their talk and went to the next formation. After all, the examination wasn't over yet. One by one, they kept examining the formations of the participants.
After some time, they arrived at Rean's formation. If there was someone they were more interested in than anyone else, that would be Rean. After all, he had gotten to this point using unconventional means. Just what did he create this time?
"Rean Larks, 1st place in the last phase. So, does it work?"
Rean smiled as he nodded.
"It works very well. There is a lot of room for improvement since I came up with this idea on the spot, but it's definitely a life-changer for ordinary people."
As he said this, he thought to himself.
'Especially since it would work several times better once I make it into a Circuitry Formation.'
Turin, Saya, and the other elders nodded.
"Very well. What does it do?"
"It's a Water Reclaimer Formation."
"Reclaimer? What do you mean?"
Rean nodded as he explained.
"In short, it can get rid of impurities in the water so that it can be used again. It's that simple."
