"Pang Shangshu, so this spirit fluctuation transmitter ...... The effect is that two people can communicate silently? Yu looked at the civil officials in front of him with two hats together, and they were communicating with each other with "spiritual power", and his face was a little ugly.

First, Yu turned his brows and bitter face all the year round, which is a standard expression, and secondly, he ...... It's such a thing, and it requires the household department to allocate a large amount of money to research and produce, which makes Yu Fu very uncomfortable.

At this time, Bai Tu was holding a palace meeting, preparing to make Pang Tong's "fine report" first recognized at the court level.

"The main effect is not silence, but distance...... Theoretically, as long as Jinglan can be connected to as far away, the information can be transmitted almost synchronously within the range of how far away. Pang Tong also said with a straight face.

As the head of the Ministry of Industry, Pang Tongyi has no good impression of the household department that picks and searches!

Don't look at Pang Tong did not enter the cabinet, but in terms of status, it can be said that he has reached the level of "transcendence" in the Chu State.

Pang Tong also didn't say half a sentence, because there is no rubber, the durability of the fine cable is very poor, so in the end, it must be laid in small sections and small sections.

"That is, in this way, can the original signal tower be replaced? No...... If the intercity 'fine cable' can be laid directly, there is no need for signal towers, so that major cities can communicate with each other in real time? Lu Su's eyes lit up when he heard this.

If there is really such an effect, how important it will be for the Chu State, everyone present knows it......

Of course, it is only "knowing", and it is still impossible to fully understand what this kind of information dissemination method that can make the concept of "land" change dramatically, and what it can bring!

"Theoretically, yes, but only if the cable isn't broken, so it's best not to be too long...... But certainly much farther than a signal tower. Pang Tong said.

The "telegraph" system, similar to the "fine newspaper", was a product of the mid-19th century in history without the White Rabbit effect.

It was also originally established in the form of "wired", until the turn of the 19th and 20th centuries, wireless telegraphy began to appear, that is, in various spy war films, the kind of equipment that does not seem to be large, but can communicate over various distances!

However, now Pang Tong's "cable fine report" is still in its infancy......

First of all, the threshold for receiving and sending signals needs to be lowered - otherwise, every signal station must put an official with two ** divine powers?

Even if it is the talent reserve of Chu State, it is not enough for such a disaster!

"In this case, the minister asked for the order to lay it in Jinling Mansion first, in order to see the aftereffect, if there is really such a miraculous effect, and then according to the priority, prepare to lay it between the prefectures and states." Lu Su suggested.

Lu Bu took the spiritual fluctuation transmitter and examined it in his hand, although he didn't find anything, he still said, "Is this somewhat similar to the messenger on the battle armor?" However, the herald on the armor does not need a line...... Pang Shangshu can refer to it from the aspect of battle armor. ”

"Envoy Lu is reasonable, in fact, I have observed it before...... It's a pity that I couldn't detect the fluctuation of the transmitter on the armor, maybe it's not the same. Pang Tong also showed some thought when he heard this.

Indeed, this effect cannot but be reminiscent of one of the functions of the Warframe - communication.

Within a certain range, generals can send messages to other generals through their armor, of course...... The Warframe's transmission is wireless, and the transmission ability is related to the general's own ability, and can be increased by the "Shuai Banner".

According to Pang Tong's experiment, this ability to transmit information should be fundamentally different from the "fine wave", not a wired and wireless problem, but the fluctuation of the war armor to transmit information, Pang Tong can not be found through the existing experimental means, the only thing that can be confirmed is that in the case of unstable military morale and chaotic war situation, this ability to transmit information will be weakened.

Other words...... This kind of signal will be affected by the "emotion" emitted, so can it be deduced that this signal itself is also similar to the fluctuation of "emotion"?

In comparison, this is closer to "psychic communication"!

Moreover, it is a pure spiritual power communication, and Pang Tong's "fine report" is after all converting spiritual power fluctuations into "radio waves", or making spiritual power propagate in the electric field.

As for the spiritual power that spreads out of thin air, let alone how it is received, with the current means, Pang Tong can't even detect this kind of fluctuation!

And you must know that the signal transmission of the battle armor is only related to the generals, and the middle and grassroots generals who receive the information do not have any requirements for mental power - of course, they cannot take the initiative to send messages in reverse.

Although it is incomprehensible for the time being, it does give Pang Tong some inspiration, such as the propagation of radio waves......

It's just that now the cable is still in its infancy, and Pang Tong is not ambitious.

Huang Chengyan thought about it again and again, and then specially proposed: "If it can really be promoted, Jiangling and Xiangyang should be in the first priority." ”

Relatively speaking, the state of Chu is still very harmonious, but there are also different voices.

After all, unlike when there was one place and one city, as the power expanded, new interest groups were constantly joining, and it was impossible to have no differences at all.

During the Three Kingdoms period, Wei, Shu and Wu all reached the point of blood in this regard - the change of Gao Pingling in Wei and the dispute between the two palaces of Wu, which was not a reshuffle of the court? Shu is relatively better, but ...... Jiang Wei led his troops outside in the later period, and he didn't even dare to return to the city, for fear of being detained by other traitors, and the internal chaos could also be seen.

In contrast, the Chu State is not a big problem now, and the sharpest disagreement is the dispute between Jingyang, or the dispute between the Nanjun Shi clan and the Jiangdong Shi clan.

After all, before the establishment of the Chu State, the two sides were in a state of confrontation for a long time, and at the beginning of the establishment of the Chu State, the Jiangdong Shi clan used their understanding of the construction of the workshop to take advantage of the initial stage of Jingzhou's industrialization construction to pick up a handful of wool, and now many workshops in Jingzhou are established by the Jiangdong Shi clan!

Bai Tu didn't stop this too much, after all, the Jiangdong Shi clan was the team at the beginning of the Chu State, and it was already very interesting to be able to treat the Jing Yang Shi clan equally, did Bai Tu have to suppress his cronies and support those who surrendered reluctantly?

What's more, in terms of laws and regulations, it is obvious that the Jiangdong scholars have a deeper understanding, and often when it comes to the official face, it is also the Jingzhou scholars who suffer.

The state of Chu also took the opportunity to support a group of original second-rate scholars in Jingzhou to "dilute" the prestige of the original Nanjun families.

Of course, compared with the rule of other princes, the degree of Jingyang's dispute can even be described as "positive energy".

After all, in other aspects, whether it is the opening of the official workshop or the appointment of officials, Baitu is still a bowl of water "as flat" as possible, especially in terms of infrastructure...... Hanshui Weir is in Jingzhou!

For this alone, no one dared to say that Chu was partial to Jingzhou......

At this time, Huang Chengyan proposed to include Xiangyang and Jiangling in the information network that will be formed in the future, obviously in order to further narrow the "distance" between Jingzhou and the center.

The more convenient the communication, the weaker the barriers.

Jia Xu mentioned: "If it is a deep mountain or a seabed, is it easy to lay?" ”

"It is a bit difficult to construct in the deep mountains, but considering that it is not easy to be damaged if it is inaccessible, you can consider shallow paving, which is actually the easiest in theory, but it requires the determination to suffer losses and some luck...... and better and corrosion-resistant insulation. Pang Tong replied.

Jia Xu didn't say anything more, but everyone understood that he wanted to talk about the overseas places of Yizhou, Bozhou, and Zhouhu, as well as the southern part of Jingyang, where dense forests are widespread and roads are difficult to repair!

It's just that Jia Xu won't say it so thoroughly, and he will have to wait for others to mention it later.

In contrast, Lu Su and the others were obviously more confident in the deep mountains and old forests, after all...... The words of the ocean, even the current Chu State, do not dare to say "understand".

In their imagination, it is more difficult to lay such a "fine cable" in the middle of the sea, and it has to cross thousands of miles without any transit, than to lay it in the deep mountains and old forests.

Although Pang Tong mentioned "the easiest", what luck, determination, and unclear "insulation" and the like were mentioned later, obviously it can't be done right now, right?

In fact, in this regard, the laying of submarine cables is far less difficult than they imagined, especially this kind of cable that only transmits signals, not transmits high-power electric energy!

Historically, not long after the advent of the cable telegraph, attempts were made to lay them across the ocean, and they were declared successful more than a decade later, also in the middle of the 19th century......

The principle is very simple, there is no need for any subsea work, that is, prepare a long enough cable on the ship, and then put it down with a winch little by little during the voyage, and the ship will be successful after driving to the destination.

When the first transoceanic cable was laid in history, the only "technical upgrade" was to cross the Atlantic Ocean from one ship to two ships each with half of the cable, meet in the center of the Atlantic, connect the cables, and then sail to destinations at both ends.

It sounds like child's play, and it's as simple as digging an undersea tunnel in the United States, as if two people can dig it with a hoe on their shoulders......

However, the first transoceanic cable was successfully laid in this way!

Of course, behind the success, there are also many sadness and blows, as Pang Tong said, this requires "luck" - the builder of the transoceanic cable, "Cyrus Westfield", also succeeded after many failures.

Every failure not only means that there is no return on the large sailing expenditure, but also ...... And the cable was squandered!

More importantly, in the eyes of the people at the time, this matter was too difficult, so there were doubts about it in their hearts, and both the people and shareholders began to doubt whether this matter was reliable after the failure.

If it weren't for Field's insistence, I'm afraid it would be a long time before the submarine cable, which has a simple principle, will appear.

It is also after the success that everyone found that the submarine cable is actually much smaller at the same length, after all, as long as it sinks to the bottom of the sea, it does not need to be buried deep or raised!

It's just that when laying, the fault tolerance rate is very low, and if there is a storm during laying, even if the ship is fine, most of the cables will be scrapped......

However, for the current Chu State, there is a big problem with submarine cables - insulation!

The state of Chu, which has not yet introduced rubber, has always been very weak in this industrial sealing.

Now the insulation layer of the "fine cable" is the mode of "paint insulation + thick tarpaulin waterproof", if you want to build for a long distance, you can only choose to bury it underground, the durability is very poor, you can't stand the wind and rain, and the seabed is ...... Don't even think about it!

Although it is still impossible for everyone to understand the miraculous construction of the submarine fine cable, the "fine wave transmission" of the Ministry of Industry has still been supported by the palace and the project has been officially established......
