Jia Yi stood on the bow of the ship, and another ray shot out in his hand, and a huge ice floe immediately condensed on the sea.

"Quick, quick, go down and pull the ice back. ”

When they saw the ice floe, the people on the boat immediately put down the boat and went to pull the ice back.

Although it is early winter, there is no ice on the sea, and these sailors like the ice cubes that Jiayi used to freeze with his spell, the temperature is very low, and it tastes best to chill the ale. Kaichi has been experimenting with spells for the past two days, and after each spell, the ship's crew will go and pull the ice back.

"This ice cube is getting bigger again. The crew members of the small boat whispered to each other after pulling the ice.

"I heard that the other party is experimenting with new spells, otherwise do you think he is idle and boring, standing on the bow of the ship every day for the past two days and releasing spells into the sea. Maybe it's because the magic has become more powerful. ”

They didn't dare to discuss too freely, and stopped the discussion when they pulled the ice to the side of the big boat.

Jiayi is indeed experimenting with spells, which is the use of compressed air for refrigeration, which can separate the energy in the air, and the principle is actually the use of vortex tubes. When the compressed air expands and enters the vortex tube, the air flow rotates at high speed in the vortex tube, which separates the heat in the air, and the temperature in the center of the air flow becomes lower and shoots forward, and the temperature on the periphery becomes higher and sprays backward.

This is essentially the separation of heat from the air and the refrigeration.

Kaichi has been adjusting this spell these days, hoping to get a cooler air flow. Because it uses a high-velocity air stream and separates the heat, this spell consumes less mana and can reach lower temperatures. Compared to the Ice Ray, the velocity of the air flow is also faster, and there is piercing damage.

However, this spell can only go straight forward, and it is not easy to control after the high-speed air flow is shot out, and Jia Yi can use his powerful mental power to control it slightly, but the angle cannot be too large, and the requirements for control are higher.

The most important thing is that you can't stand behind you, otherwise you will be burned by the high-temperature air jets coming out at high speed. It's like a rocket is being fired.

This is a spell he has come up with after studying thermodynamics recently, and he has adjusted it all the way, and now it is almost perfected.

Of course, no spell is perfect, but for Kaichi, this spell he invented himself is the most suitable for him, and he is more comfortable to control.

......

They soon arrived at the next port, and after a month of sailing at sea, Kaichi felt his legs go a little weak when he walked to the ground.

Seeing land, he took the lead and ran to the dock.

This is a not particularly large port, mainly as a transit station, the entire Beisen Continent has since the Silver Sword Empire, all the way to the Maritime Federation, this coastline has been blocked by the Hengduan Mountains, so there are only a few small ports on the coastline here, as a transit station.

Although these coastal countries nominally have coastlines, they are not much different from none.

It's also because there aren't many supply points along the way, so they can't miss every supply point.

Although this supply port is not large, it is here that Kaichi finds the Mage Guild, a tower made of black basalt.

Almost all mage guilds seem to be crowded in front of the door, and most people will not go to the mage guild without special things. Although it is not explicitly stated that ordinary people are not accepted, there are not many services that non-teachers and high-level professionals can receive in it.

Kaichi walked in, went to the front desk first, and asked, "Is there an up-to-date magazine?"

The mage apprentice at the front desk hurriedly saluted, and then returned: "Yes, the latest issues of "Wizard Monthly" and "Magical Wonders" are here. ”

After thinking for a while, the other party added: "September's." There are also "Electromagnetism" and "Elements", there is a lot of discussion about heat mass on the elements, basically every mage will buy a copy and take a look, after all, the fireball technique is basically a spell that every official mage will learn. ”

It's November now, two months ago, but that's not bad, in the Maritime Federation, many magazines are half a year ago, and 2 months is really not long.

As if to see that Jiayi's expression was wrong, the apprentice said: "I heard that the Supreme Council is planning to cooperate with the Mage Association and various magazines, and is preparing to open printing departments of magazines in various places, and transmit the contents of the magazines by telegram, and print and sell them on the spot, so that it can be much more timely, and there is no need to buy expired periodicals." ”

As he spoke, the apprentice cautiously stretched his head over and said softly: "I heard that last time someone published two papers in a magazine in a row, that is, about telegraphy, at first it was just a copper crystal telegram, and then it was put forward to put forward a theory, and finally even a specific physical object was made, because of the delay of papers in other places, many people have studied wireless telegraphy for a while after seeing the telegraph theory, but they don't know that this is outdated. ”

What he said made Jia Yi swallow his saliva, and he couldn't imagine that this legend had been circulating in the rivers and lakes. However, the other party thought that Jia Yi was thinking about what to do if he encountered this situation, and he was afraid.

Every mage will have this kind of fear, and if they succeed in their own research, they will collide with others, and then their own achievements will be wasted. However, for mages, encountering this situation is not without gain, and the understanding of spells gained along the way will not disappear.

It's just that even then, no mage would be willing.

This fully illustrates the importance of the opening question.

Jia Yigan laughed a few words and said, "Even if it is a telegram, it is very difficult to transmit an entire magazine, and there are still so many copies. Besides, the typesetting can't be transmitted. ”

Unless a fax machine is available now, it may not be practical to use a telegraph.

However, it is possible to use this to develop a newsletter that gathers some of the most important information and publishes a summary of the magical journal, which is much easier to transmit by telegram.

The apprentice also felt that what Jia Yi said was very reasonable, there were not many mage associations in various places, and if they wanted to accept so many magazines, it would be too busy, unless they didn't do anything else, or expanded their staff, but these two associations probably wouldn't choose.

"I don't know, but I've heard it mentioned on the public telegraph channel, and our president always says that. ”

"Public telegram channel?"

"Don't you know?" the apprentice was also a little curious, seeing that he was familiar with the telegram, he thought that Jia Yi would know, "The Supreme Council has defined the various frequency bands of the telegram, divided the use, and will not easily enter other channels in the future." Moreover, the parliament has its own public telegraph channel, which will send some latest news and some policies of the Supreme Council every night through this telegram. For example, the fact that all mages need to change their badges is known to many mages after being notified through the public channel. ”

[I didn't expect that there was even a broadcast.] Kaichi scratched his head a little in his heart, it was the first time he had heard of this kind of telegraph broadcasting.

He hasn't played with the telegram himself for a while, so I don't know, there are more interesting things about the telegram.

In the beginning, every mage was particularly curious about telegraphs, especially as the treatise on wireless telegraphy expanded, and Lord Magnay disclosed his invention, so that every mage was free to make and modify telegraphs. Accompanying that paper was the wireless telegraph that sprung up like mushrooms all over the place.

Then, there was the endless stream of telegraph signals floating over the continent, and "each" mage sent signals into the air, then listened to the messages in the air, looking for feedback. Some conservative mages believe that countless ghosts have been floating over the continent all the time.

The mages were so enthusiastic about telegraph communication that they were like people visiting forums in the early days of the Internet, and they would make friends on forums – they were telegraph friends.

Some people even said that they received the signals of Leizhou and Elf Island, but one of these two places is too far away, and there is a thunder layer on the western plateau, and the electromagnetic storm is very strong, so it is difficult to receive the signal from these two places.

Later, on the basis of Jiayi's code, the Supreme Council re-regulated the frequency bands and other contents, unified the telegraph in the public domain, and opened up a part of the channel as the official channel, but now only one Supreme Council bulletin is sent out regularly every night.

He hadn't asked when he was in Helga, and if the apprentice hadn't told him, he wouldn't have known until Moshacher. ntent
