Regarding whether to build a castle, Mao Geng thought, of course, it should be built......Updated very quickly. The reason why it was not built in Kaohsiung was because the water and land army of the Song Dynasty was protected, and the indigenous people in Taiwan were very poor in combat, and the two barbed wire mesh was enough to repay the safety.

But Sakhalin Island is different here, it is far away from the Song Dynasty. Moreover, when the Jin soldiers attacked, the Song Dynasty might not send troops to support it, and there was not much force on Xiayi Island, so everything could only rely on itself. Well, to deal with the cold weapon siege army of this era, the city is the best defense reliance.

There are two classic cases in history that are worth learning from. One is Zheng Chenggong's besieging the city of Relanzha, and the other is the battle of the Qing army besieging the city of Yaquesa. Both battles were between large armies dominated by cold weapons and siege the city of Relanzha, with only more than 2,000 defenders. It took a full nine months to force the Dutch to surrender. The Qing army besieged the city of Yaquesa, with only more than 800 defenders. It took ten months to capture Yaquesa. Judging from these two cases, as long as the city is defended by cold weapons, it is difficult for the siege army with only cold weapons to help the defenders with firearms.

Mao Geng did not think that the army of Jin soldiers could be defeated in the field, although there were also examples of wars that could be learned from. For example, in the Battle of Baliqiao in the Second War, 8,000 British and French coalition forces fought 30,000 Qing troops in Baliqiao, but they were defeated by the Qing army. In this battle, only 12 British and French coalition forces were killed. However, the Qing army in the late Qing Dynasty was definitely not as powerful as the current Jin soldiers. Moreover, the Jin soldiers were likely to mobilize more than 50,000 troops, from 5,000 to 50,000, one to 10, Mao Geng felt that the hope of victory was a bit slim.

Of course, standing on Ma Fen's horn, he also cited a case that supported his views, that is, Zeng Guoquan's siege of Anqing. Zeng Guoquan's siege of Anqing, had more than 20,000 defenders inside and tens of thousands of sieges outside, but Zeng Guoquan relied on two long trenches, the inner trenches used for siege, and the outer trenches used for siege, and the outer trenches used for hindering aid. After four months of persistence, he finally captured the important town of Anqing and laid the foundation for the victory of the Hunan Army. It can be seen that trenches are very useful in dealing with large armies dominated by cold weapons. If wire fences are added, Ma Fen believes that as long as there are five thousand "elements" and auxiliary soldiers, it should be no problem to defeat the attack of 70,000 or 80,000 Jin soldiers. Besides, several bunkers can be built to shoot and shoot condescending firepower. Under this three-dimensional defense line, the Jin soldiers can only cry.

However, Ma Fen is a minority, and Tang Kai only has two votes. Most people still think that building a castle is much more reliable from the bottom of their hearts. Based on the principle of safety first, even Isain holds this view. Therefore, the castle faction is firmly in the upper hand and does not need Mao Geng to use the authority of leadership, so he decided to build a castle.

Despite this, Ma Fen's suggestion also worked. The final plan was to build a small inner city castle. The castle was square, with a length and width of two kilometers. This was the last to save life. In the outer circle, according to Ma Fen's suggestion, dig trenches, set up two wire mesh, and build a bunker.

This is a double insurance plan, with several more insurance lines on the Dongrui defense line, and most time travelers said that this is very necessary.

As long as the Dongrui defense line is successfully built, Mao Geng also feels that even if the Jin soldiers are 100,000, they may not be able to seize them in one or two years.

Now the inner city has been dug up, and some areas have been built to half a meter high, but the project volume is really large. I hope that the inner city can be completed before the winter begins. It has to be said that building a castle is a large-scale infrastructure project that consumes resources. Now it is not as overcapacity as in later generations, and steel and cement are not enough. Therefore, infrastructure construction is often started to stimulate domestic demand in later generations. Now there is even a shortage of bricks in Sakhalin Island, let alone cement. Therefore, this castle is indeed very expensive. If it weren't for saving lives, Mao Geng wished he could stop the project immediately.

At the meeting, Tang Kai wanted to increase his troops by 10,000, but Ma Fen had just added a thousand troops. We have a high style, so we can give in and increase a thousand troops by 10,000!

The majority of soldiers are not about "element". If you hold eight thousand "elements" soldiers and have various new weapons, Ma Fen feels that he is confident.

However, Japan's labor exporters only arrived in a group, and the first batch of 2,55 people had already been sent to the construction site, and they had to wait for the next time. In fact, Ma Fen was still a little worried about whether the Japanese could act as qualified cannon fodder. As for what to do if the Japanese were injured or killed, they came to work after all, not to work hard. Ma Fen was not worried about this. We time travelers are not short of money now, and if they die, it is nothing more than making up for the poor Japanese.

The matter of increasing troops came to an end. Mao Geng felt that balance was really a hard truth, and his mood began to relax, so he turned to another thing:

"Please come here, I'm telling you that the radio test has been initially tested. This is all Lao Peng's credit. Come on! Let's applaud and congratulate Lao Peng's radio for its successful success."

"How far has the test distance been?" Lin Lishi was so busy that he didn't touch the ground. Although he heard that the radio was testing, he didn't pay attention. The transmission distance of the radio was of course the most important, so he asked this question.

"In order to conduct the test, I used our treasure - the lightning speedboat. Lao Lin, tell you, I drove the boat to the northernmost end of Sakhalin Island, and from there to Dongrui Town, it was almost a thousand kilometers away. Lao Peng had good skills and the things he made were very good! The results of the transmission and reception tests were good. Don't look at the thing Lao Peng made, a few ores can receive radio signals. The fire "flower" transmitter is also simple, simple, but the effect is really good. Lao Peng, you are awesome! The local method will solve the big problem. Thanks to our old Bloomberg's talent, he actually knows the antique ore detector "wave" device, otherwise he would have to pull wires around and only rely on wired telegrams to communicate."

Liu Bin personally participated in the telegram transfer and reception test, so he praised Lao Peng's telegram machine.

This Sakhalin Island is more than 980 kilometers long from north to south. This successful test means that radio communications can at least cover Sakhalin Island, which is really a happy event.

"Oh, are you using the Morse password?" Tang Kai was naturally very excited, because the biggest purpose of this thing is military.

"Xiao Tang, you don't understand this! I want to criticize you, how can I say that! There is no Morse code in the world anymore, and the only one that will be recognized by the whole world in the future is Peng's code."

Liu Bin used a teasing kiss to the 'kiss' to the head of Lao Peng. Lao Peng was still happy. But at the same time, Lao Peng felt a little blushing, so he said modestly:

"We are indeed not using Morse code. Morse code is the Intrael code. It uses binary numbers to represent 26 letters respectively. Of course, we don't use Intrael code. We use the CEL code, which is similar to the CEL code invented by Waikijie in history. The binary code numbers are used to indicate the position of the characters. We selected 6,000 commonly used Chinese characters and compiled them into a codebook with one page of characters. A binary number can determine which page, which line, and column the word is on. According to Tujun, it can be translated into the electric. This has no technical content. In the computer technology of later generations, binary is the knowledge of entering the "door". So, please! Don't "chaotic" the Peng's password. If it is called that, I, Mr. Peng, have an objection."

Most of the people here have never heard of this, so Lao Peng quoted the classics and told the story of the earliest inventing Chinese characters.

By the way, it is really inconvenient to use Morse code to send and receive Chinese telegrams. The sending of newspapers requires "Chinese translation of English" and the receiving of newspapers is not complicated. The words may not be expressed due to translation. In order to facilitate the use of telegrams in China, in 1873, French personnel stationed in China, Wiggiejie, referring to the arrangement method of the "Kangxi Dictionary", selected more than 6,800 commonly used Chinese characters and compiled the first Chinese code book, called "New Book of Telegram". The set of telegrams in "New Book of Telegram" also uses numbers as coordinate values, and can be translated into the illuminated code book.

After solving the problem of wireless communication, everyone here was very excited. Ma Fen was still unsatisfied and proposed to further test to see if he could send a telegram directly to the Song Dynasty. If he could contact Lin'an and Kaohsiung directly, it would be best.

As a result, the remote testing incident fell on Isain.

After all, Liu Bin is responsible for coastal defense. Coastal defense is a major event, and the navy's training is also in a critical stage. As for the other time travelers, they are responsible for a lot of things, and they are all unable to escape. Only Isa is a little idle, so she decided to take on this long-distance test.

Isa arrived at the first stop of the test in a lightning speedboat, Yuling Island, within a day.

Yuling Island is 120 kilometers east of Goryeo, with an area of ​​73 square kilometers. Most of the islands are forests and not many people live there. Later Koreans quoted classics and claimed that in the Song Dynasty, people here paid tribute to Goryeo. The implication is that Goryeo is now managing Sakhalin Island. However, time travelers have not yet found traces of Goryeo setting up management agencies here.

Last year, Lin Gui's team visited Yuling Island once, captured a group of indigenous people here, and sent them to Sakhalin Island for a sum of money. Later, Han Huanzhang's team visited again and captured a group of people. Han Huanzhang was not satisfied with this and strongly suggested that Ma Fen occupy Yuling Island because the geographical location here happened to be on the way to Sakhalin Island north. If it was occupied, it would be easier to replenish. On the contrary, if it was occupied by the enemy, it would pose some threat to the great time travelers.

Ma Fen, a typical expansionist, immediately followed the good and sent two people to set up a base here.

The plan of the time traveler is to establish a telegram transfer station here, and through telegram relay, you should be able to directly access Lin'an. Considering the confidentiality of the communication, Yuling Island can be regarded as a good communication transfer station.--32133+dsuaahhh+25793050-->
