As for whether to build a castle, Mao Geng believes that of course it should be built. The update is so fast. The reason why it was not built in Kaohsiung was because it was protected by the 6 armies of the Great Song Dynasty, and Taiwan's indigenous combat strength was very scummy, and two barbed wire fences were enough to report peace.

But Sakhalin Island is different here, it is far away from the Great Song Dynasty, not to mention that when the Jin soldiers attack, the Great Song may not send troops to support, and there are not many troops on Xia Island, so Yiqiē can only rely on himself. Well, to deal with the cold-weapon siege army of this era, the city is the best defense to rely on.

Historically, there are two classic cases worth learning from. One is the battle of Zheng Chenggong's siege of the city of Geranza, the second is the battle of the Qing army besieging the city of Yaxa, both battles are based on cold weapons of the army to besiege the fortified castle, Zheng Chenggong with 25,000 people to besiege the city of Geranza with only more than 2ooo defenders, it took a full nine months to force the Dutch to surrender, and the Qing army of thousands of people besieged the city of Yaksa, which was only defended by more than 8oo people, which took ten months, and still did not capture the city of Yaxa. Judging from these two cases, as long as the city is firmly entrenched, it is difficult for the besieging army with only cold weapons to help the defenders with firearms.

Mao Geng did not think that he could defeat the army of Jin soldiers in the field, although there were also examples of battles that could be used for reference. For example, in the Battle of Bali Bridge in the Second War, the Anglo-French coalition army 8ooo fought with 30,000 Qing troops at Bali Bridge, and the result was a great defeat of the Qing army, and the Anglo-French coalition army only lost 12 people in this battle. But the combat strength of the Qing army in the late Qing Dynasty is definitely not as good as the current Jin soldiers, not to mention that the Jin soldiers are likely to mobilize more than 50,000 troops, with 5,000 to 50,000, one to ten, Mao Geng feels that the hope of victory is a bit slim.

Of course, standing on the corner of Ma Fen, he also cited a case that supported his view, that is, the battle of Zeng Guoquan's siege of Anqing. Zeng Guoquan besieged the battle of Anqing, there were more than 20,000 defenders inside, and tens of thousands of Ping troops besieged outside, but Zeng Guoquan relied on two long trenches, the inner circle of the ditch was used for siege, and the outer circle of the ditch was used to block reinforcements, so it persisted for four months, and finally captured the important town of Anqing, laying the victory of the Hunan army. It can be seen that the trenches are very effective against an army dominated by cold weapons, and if barbed wire is added, Ma Fen believes that as long as there are 5,000 'elite' troops and auxiliary soldiers, it should be easy to thwart the attack of 70,000 or 80,000 gold soldiers. Besides, a number of pillboxes can also be built to 'shoot' condescending firepower, and the Jin soldiers can only cry under this three-dimensional defense line.

However, Ma Fen is in the minority, and Tang Kai only has two votes, most people still feel that building a castle is much more reliable in their hearts, in line with the principle of safety first, even Ishayne also holds this view, so the castle faction has the upper hand, and there is no need for Mao Geng to use the leadership authority, so he set a plan to build the castle.

The final plan was to build a small inner castle, which was square in length and two kilometers in length and width, which was finally used to save lives, and in the outer circle, according to Ma Fen's construction, digging trenches, erecting two barbed wire, and building blockhouses.

This is a double insurance scheme, with several more insurances on the Dongrui defense line, and most traversers say that it is necessary.

As long as this Dongrui defense line is successfully built, Mao Geng also feels that even if the Jin soldiers are 100,000 soldiers, I am afraid they will not be able to gnaw it down in a year or two.

Now the foundation of the inner city has been dug, and some sections have been built to a height of half a meter, but the amount of work is really a bit large, and I hope that the inner city can be completed before winter. I have to say that the construction of the castle is a large-scale infrastructure project that consumes quite a lot of resources, and now it is not as overcapacity as in later generations, reinforced concrete or something, there is no excess, so later generations often have to start infrastructure construction to stimulate domestic demand, and now Sakhalin Island is even short of bricks, not to mention cement, so this castle is indeed a huge expense, if it is not important to save his life, Mao Geng hates to stop the project immediately.

At the meeting, Tang Kai was clamoring to increase the number of troops by 10,000, but Ma Fen was almost the same as increasing the number of troops.

If you have 8,000 'fine' soldiers and all kinds of new weapons, Ma Fen feels that he is still very confident.

However, only one batch of Japanese labor exporters has arrived, and the first batch of 2,050 people has already been sent to the construction site, and they have to wait for the next time. In fact, Ma Fen is still a little worried, whether the Japanese can act as qualified cannon fodder, as for what to do if the Japanese have casualties, after all, people are here to work, not to sell their lives, Ma Fen is not very worried about this, we are not bad for money now, and if they die, it is nothing more than making up some money for the poor Japanese.

The matter of increasing troops came to an end, Mao Geng felt that balance was really the last word, and his mood began to become relaxed, so he turned to another thing:

"Please come, I want to tell you that the radio test has been preliminarily successful, and this is all the credit of Lao Peng, come on! We applaud and congratulate Lao Peng on his radio success. ”

"How far has it been?" Lin Lishi was busy with his feet not touching the ground, although he also heard that the radio was testing, but he didn't pay attention to it, the transmission distance of the radio was of course the most important, so he asked.

"In order to carry out the test, this time we did not hesitate to use our treasure - the lightning speedboat, Lao Lin, let me tell you, I drove to the northernmost point of Sakhalin Island, from there to the town of Dongrui, a distance of almost a thousand kilometers. Lao Peng's craftsmanship is good, and the whole thing is very competitive! The results of the test are good, don't look at this thing that Lao Peng did, a few ores can receive radio signals, and the spark 'flower' is also simple, simple is simple, but the effect is really good. Lao Peng, you cow! Indigenous solutions to big problems. Thanks to our old Bloomberg's talents, we even know about antique ore detectors, otherwise we would really have to pull wires everywhere and rely on wired telegraphs to communicate. ”

Liu Bin personally participated in this telegram receiving test, so he praised Lao Peng's telegraph.

Sakhalin Island is more than 98o kilometers long from north to south, and the success of this test means that radio communications can at least cover Sakhalin Island, which is really a great joy.

"Oh, is it Morse code?" Tang Kai was naturally very excited, because the biggest use of this thing was the military aspect.

"Xiao Tang, you don't understand this! I'm going to criticize you, how can you 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 the Peng code. ”

Liu Bin used a ridiculous 'tone' to attribute the password to Lao Peng, and Lao Peng was still happy in his heart. But at the same time, Lao Peng felt a little blushing, so he said modestly:

"We do not use Morse code, Morse code is English code, with binary numbers to represent 26 letters, of course we do not use English code, with the Chinese code, and the history of Waiki Benjamin's code is similar, binary code numbers are used to indicate the position of the word, we selected six thousand commonly used Chinese characters, compiled into a page of the word code, a binary number can determine which page, which line, which column, according to the figure, can be translated into electricity, this has no technical content. In later generations of computer technology, binary is the entry 'door' knowledge. So, please! Everyone, don't 'mess' with what Peng's password is, if it's called like this, my old Peng Ke has an opinion. ”

Most of the people here had never heard of it, so Lao Peng quoted the scriptures and told the story of the earliest Ming Chinese characters and clear codes.

In order to facilitate the use of telegrams in China, in 1873, the French personnel stationed in China, Wigkijie, referred to the arrangement of the "Kangxi Dictionary", selected more than 68oo commonly used Chinese characters, and compiled the first Chinese character code book, called "New Book of Telegraphs". The set of "New Book of Telegraphs" also uses numbers as coordinate values, and the illuminated code book can be translated.

The wireless communication problem was solved, and everyone present was very excited. Ma Fenwu was still unsatisfied, and proposed to further test to see if he could directly send a telegram to the Great Song Dynasty. It would be best if you could get in touch with Lin'an and Kaohsiung directly.

As a result, the matter of remote testing fell to Issain.

After all, Liu Bin is in charge of coastal defense, coastal defense is a major matter, and the training of the navy is also at a critical stage, as for the other traversers, they are also responsible for their own affairs, and they can't get out of it. Only Isa was a little free, and as a result, she was appointed to undertake the expedition test.

Isa was on a lightning speedboat, and within a day, she came to the first stop of the test - Ulleungdo.

Ulleungdo is 12o kilometers east of Goryeo, with an area of 73 square kilometers, the island is mostly forested, and there are not many people living on it. However, there is no trace of the current Korean people setting up an administrative structure here for the time being.

Last year, Lin Gui's team visited Ulleungdo once, arrested a group of aborigines here, and sent them to Sakhalin Island for a sum of money. Later, Han Huanzhang's team came here again and arrested a group of people. Han Huanzhang was not satisfied with this, and strongly proposed to occupy Ulleung Island, because the geographical location of this place was exactly on the way north to Sakhalin Island, and if it was occupied, it would be convenient for supplies, on the contrary, if it was occupied by the enemy, it would pose some threat to the great traverser.

Ma Fen is a typical expansionist, and he immediately sent two people to set up a base here.

The traverser's plan is to build a telegraph relay station here, and the way to pass the guò telegraph relay should be able to go directly to Lin'an. Considering the confidential nature of communication, Ulleungdo can be regarded as a good communication relay point - 32133 + dsuaahhh + 25793o5o - >
