After hearing that Roan had been reading all the time, Rean left it be. He looked at all the materials he got and used Guliva's token to get ahold a few cultivators with Fire and Water Affinity. Rubber wasn't hard to make, but dried sap would work almost the same way and would be even faster. Rean only wanted to test it out first, so he went for the simplest form.
He made five teams with those Fire and Water Affinity cultivators. He then separated five big tubs with the sap and began to use Spiritual Energy to hold the copper cable. A cultivator then used his Spiritual Energy to run the cable inside one of the tubs, which would exit the other side completely covered in the sap. The Fire and Water cultivators would then stay between each tub and use their Elemental Affinities to solidify the sap. The cable covered in dried sap would then enter another tub and the process repeated. Simply put, Rean had the cables insulated with dried sap five times to guarantee that the insulation wouldn't be too thin.
All the Fire and Water cultivators Rean got were at the Foundation Establishment Realm. That's because this process would take a lot of time if you had to stop to recover Spiritual Energy too often. Foundation Establishment cultivators would take much longer to run out of energy and could recover much faster.
Although no one understood what was happening, they were all part of the Iron and Blood District. Rean also had elder Guliva's token. Besides, Rean wasn't making them do it for free. He was even paying everyone with the Rank 1 Spirit Stones. The majority didn't have a significant background or a business like Rean, so the payment was quite good for such a simple job.
Just like that, the creation of insulated copper cables continued. It took Rean's group three entire days to cover all the wires with dried sap five times, or rubber if you prefer. It didn't look nice like the cables back on Earth but was more than enough for the purpose.
Majorias City was 300km away from Dalamu Sect's entrance. Just to make sure, Rean made an extra 10km of cables. After it was done, Rean let everyone who worked with him go back. From now on, he would need cultivators with Earth Element Affinity. After all, he would need to put these cables deep underground.
Fortunately, it was also easy to arrange with elder Guliva's token.
Talking about elder Guliva, the same had been watching Rean from far away since he started the project. When the other elders got curious about what was happening, Guliva stepped forward and told that it was a project of their district. It also wouldn't get in the other cultivators' way, so there was nothing to worry about.
To make things fast, Rean got quite a few Earth Element Cultivators. While some will be using their Spiritual Energy to make the excavation, others will be recovering. That way, they can keep working nonstop until they reach Majorias City. He also made sure to pay them as well. Sure enough, they were quite happy to receive so many Spirit Stones for doing such a simple job.
Of course, making it all the way to Majorias just to find out that it was a failure would be pretty idiotic. That being said, Rean also called two Lightning Affinity Cultivators to this project. Their job was pretty simple. One of them would stay in the Sect's entrance, while the other would be following the group as they excavated and put the cables deep underground.
Rean couldn't help but be even more impressed by the cultivation world. Such type of job would usually take quite a few machines, and the time needed to cover a certain area might take several days, if not weeks. However, with the Earth Element cultivators helping, they only poured their Spiritual Energy and manipulated the Earth Element to do the same thing. In a matter of seconds, they could make several meters deep passages with ease and cover it again.
The Lightning Affinity cultivator would them test the wire every 10km. He would gather Lightning Element with his Spiritual Energy and pour it into the cable. Naturally, the electrical current would move through all the way to the sect entrance. There, the other Lightning Affinity cultivator would be holding the other cable's end. As soon as he noticed that pulse of electrical current, he would answer with another one.
When Rean reached 30km of distance, elder Guliva appeared where the disciples were working.
"Oh, elder Guliva! Is something wrong?"
Guliva smiled and shook his head.
"Not really. I just noticed that you already reached this far, so I wanted to ask if you can still send the Lightning Element all the way to the Sect."
Rean smiled and pointed at the Lightning Cultivator, who was making the tests. The guy was taken aback and quickly reported what he did so far.
"There had been no problem, elder Guliva. I just tested the 30km mark a few minutes ago, and I could still feel the Lightning sent by Fellow Disciple Ladone back in the Sect entrance. Not only that, the amount of Lightning that I can feel from him is almost the same as when we reached 10km. If things continue like this, I believe it won't be an issue for the next 100km or even more."
Rean smiled and added.
"Also, I asked him to not pour too much Electricity inside the cable. Just enough to be easily felt on the other side. If, after another 100km, we can't feel Electrical power all the way anymore, we can simply increase the amount gathered to increase the distance."
Guliva got puzzled.
"Electrical Power? What is that?"
Rean was taken aback for a second. Only then did he remember that the Cultivation World had never heard the name ' Electricity.' For them, everything was called Lightning, Thunder, etc. Rean quickly thought about an excuse and began to explain.
"Cough, cough... I find the use of 'Lightning' inappropriate. Those are things we see during thunderstorms, or by cultivators with Lightning Affinity during attacks. Simply put, it's the name given for dangerous things. However, we are using it purely for communication. Although it could still hurt someone unprepared, the focus of the project is not to hurt anyone. I think that calling it Lightning isn't fit for our purpose, so I gave a new name, Electricity."
Guliva narrowed his eyes. He felt like this wasn't really a name Rean came up with.
Still, Guliva smiled and nodded.
"That's true. I also think that... errr... Electricity... somehow fits very well."
As fishy as it looked, it was just a name. The important thing was the purpose of this project.
'They were already at 30km of distance, and Rean said that they could at least reach another 100km without the Light- errr... Electricity power dissipating. Not to mention that it was without using too much of it. Could it be that he can really send a... electrical... signal over 300km? I better don't leave this group's side for the time being.'
Five days later, Rean's group finally reached Majorias City!
