After telling Elder Guliva about the missions he wanted to put up, Rean also mentioned that he and Roan were planning to go to Qerten. However, it would only be two months later. With that, The Sect Master could prepare the trap she was planning to.
Rean then left elder Guliva's house and returned to his room. Right after, Rean and Roan went to the cultivation tower. They receive the sect Master's authorization to use the cultivation tower without paying. Obviously, they had been using it ever since it was decided. Now, they finished both their Blacksmith and Alchemy practices, so the only thing available was cultivation.
To avoid suspicion, Rean and Roan always passed their token to the disciples who were on duty in the Cultivation Tower. The disciple would then deduct the points and give it back. However, the fact was that Rean and Roan's points never went down. Also, because the disciples on duty changed now and then, they didn't notice anything weird with the twins using the tower so much.
The days passed in a flash as Rean and Roan cultivated. Other than that, they had the every morning Iron and Blood exercises, which Roan insisted that they should take. Rean and Roan also went to the arenas quite a few times to fight against each other or other disciples. After all, only cultivation would destabilize their foundations.
During this time, the plans for constructing the electrical communication network advanced at high speeds. Dalamu Sect got the blessing of the Sasamil Imperial Family to proceed with this project. That being said, no one, not even the Royal Family of Jialin Country, tried to hinder it.
At least one-tenth of the entire sect was mobilized to this project. The Blacksmith Hall apprentices worked day and night, making the cables. The sect also issued an order to the nearby cities to gather the sap from the trees that could be used to make the rubber than Rean mentioned. However, instead of having cultivators doing it, they opened this business to the common people.
Of course, they didn't pay what Rean did in the past. Only because Rean was in a hurry that he spent so much for every ten liters of tree sap. Still, it was quite a good income for such an easy job. Besides, it was a long term one. Even with the cultivators helping to implant the project, it will take a long time until all Dalamu Sect Territory's cities are connected together. Obviously, they would need a constant stream of the correct tree sap.
Last but not least, they began to buy copper as if there was no tomorrow.
One month was enough for the first connections with the closest cities to be built. However, there was only a small problem. Some of these cities were too far away. Even after injecting a lot of Electrical current into the cable, it still dissipated before it reached Dalamu Sect. Nevertheless, when Elder Guliva came to ask Rean's opinion, Rean looked at him with a weird face.
"Cough, cough... is there something wrong?"
Rean sighed and then explained.
"I'm just surprised that you guys didn't think about it yet. Anyway, you have two choices here. First, you don't need to make a cable that goes from a specific city all the way to Dalamu. Instead, make it like a spider web. Connect a city to another, and then to the next, and the next, and the next... until you finally reach Dalamu. You can simply have the information being passed ahead."
"The second solution is through Lightning Type Formations. You already came up with a Lightning Formation that can be used to transmit messages. It creates a pulse of Electrical Power that can be read by the formation on the other side. If you really need to make a cable that long, just make a repeater formation. This formation would receive the Electrical Pulse signal in the middle of the way just before it dissipates. After that, it would activate and repeated that signal. This way, you can extend a single cable as far as you want. Not to mention that such a formation would have minimal consumption of Spiritual Energy. That being said, you might also create a repeater formation that uses the Spiritual Energy present in the surroundings. Unless the formation is broken by someone, it will keep working indefinitely."
Elder Guliva immediately noted everything down and left in a hurry. He had to have the Formations Master Hall work on it straight away. Of course, he also passed the idea of connecting the other cities together ahead.
Elder Guliva returned to ask Rean a few more things now and then, but they weren't that important. It was just that the sect was afraid of doing something wrong.
Of course, not everything was perfect. They often found obstacles that impeded them from constructing this system. Demon beasts forests, bandits purposely trying to find problems, lack of working hands, lack of material, etc. Still, this was all within Rean and the sect's expectations. No project of this size would work without any problems.
The Mission Hall was the first one to be connected to those nearby cities. After all, missions add up to 70% of all letters that Dalamu Sect receives daily. Obviously, this new communication system would be better used by them.
Of course, if there was a need to send any other information straight away, the other Halls could simply come to the Mission Hall and request to let them do it.
It didn't take long for the Sect Notice how convenient these instant communication formations were. Information that would usually take several days of birds flying back and forth could now be exchanged in a few minutes. Just how good was that?
Seeing how effective the system was, the sect increased the effort in its construction. The correct sap type collection order was issued in other cities. The sect began to pay blacksmiths outside to forge the cables too. Thanks to that, the price of copper in the entire territory of the Dalamu Sect began to rise, which forced them to seek more of it in the other sect's territories.
Of course, such a big success soon reached the other four sects' ears in Jialin Country. One month and a half after Rean and Roan began to cultivate, the Sect Masters of the four other sects came to pay a visit to Mia.
