After Mao Geng finished speaking, he opened the map and compared it in the area of Sakhalin Island, the Tatar Strait and the Great 6 in the northeast of the Jin Kingdom.

Peng Qinfang also knew that Mao Geng's pressure was a bit high, and the golden imperialism of this time and space was equivalent to the existence of the American emperor in later generations, since he was the world's hegemon, on the side of the couch, how could he allow others to snore! Sakhalin Island is so close to each other, it seems that it was originally the territory of the Jin country, and it was taken up for nothing, so it is strange that the hegemonic country of Kim imperialism wants to sit idly by! So war is a matter of time.

However, even if the golden imperialists were to go to war, it should not be so fast. Peng Qinfang stared at the map, pointed to the Heilongjiang estuary, and said:

"I heard that Han Huanzhang and Liu Wenbin sent a fleet to sweep Temple Street here, there should be few ships left by the Jin people, and there should be no threat to Sakhalin in the short term, it is estimated that even if Jin wants to attack Sakhalin, it will be next year."

Peng Qinfang believes that although the Jin people have the cavalry as a quick reaction force and the advantage of the nomads' quick mobilization, after all, the attack on Sakhalin Island is not a pure 6 war, and the Jin State has to do it, even if there are enough ships, don't think about fighting a large-scale Sakhalin attack war in a year and a half.

Mao Geng couldn't help but smile when he heard this, nodded and said:

"The truth is this, in fact, as long as the people of the Jin country don't come to fight us, even if we give the people of the Jin country a little benefit, it is not impossible. Cao Zhaoyi there, I have already asked people to go to the trick, after arriving at Sakhalin Island, I will act again, and strive to let the Jin State and the Great Song Dynasty hold negotiations around the affairs of Sakhalin Island, just talk about it, and they will talk about various plans such as the condominium of the special zone, and the people of the Jin Kingdom want benefits, anyway, they are asking for the price to pay back the money on the spot, and the Great Song Dynasty has not talked about it before, and the two countries are used to talking about it, and it is best to talk about him for a year or two. However, then Mao Geng sighed and frowned: "However, we still have to prepare for the Jin Kingdom to move troops, and we must have the necessary precautions!" Within a year, there will be at least 5,000 6 armies, and a strong fleet will have to be built, which will require a lot of manpower, material and financial resources, alas! Raising soldiers is a money-burning thing, but in this situation, it can't be burned without it. ”

At the end, Mao Geng glanced at Lao Peng meaningfully, and said with a wry smile:

"Lao Peng, you're right, it's not fun to raise soldiers to fight, and I have a headache when I think about it."

"Hehe, that's what I said, but there's nothing to worry about, Ma Fen is still not at ease with the 6th Army! It's just a matter of building a little more firearms. In addition, Han Huanzhang and Liu Wenbin were majestic on the sea during this period of time, and the sailors of the Jin people were not opponents at all, and their warships were robbed and burned. Of course, you have to burn money to raise soldiers to fight, but even if we burn three or four million guan a year, we can still afford to burn it, right! I was against burning money to raise soldiers, but for the sake of Sakhalin, I had to change my mind. ”

"Lao Peng, you don't know that firewood, rice, oil and salt are expensive, the 5006th Army, if it is only equipped with rifles and shotguns, it is not expensive, and grenades are not expensive. The problem is, we still have to equip artillery, mortars should be able to be successfully trial-produced soon, mortars are fast, just to suppress the cavalry, the problem is that there are many shells consumed, cannons, mortars, shells, are all expensive, besides, we have to be equipped with a vote of mules and horses, reindeer, Ma Fen is also preparing to build a hot ball machine armored battalion, preliminary calculations, 5,006 Army, that is two million guan. As for the fleet, it is even more money-burning, gunboats and lightning strike speedboats, their plan is to have eight ships, what is the 88 fleet, at least two or three million will have to be smashed. You see, if you smash it down with five million, you can raise such a small number of soldiers. ”

Five million is not a big deal! Peng Qin said in his heart that we didn't come to the Great Song Dynasty to save money, and if we earn it, we will spend it, and it is worth spending on national defense. As long as the mortar trial production is successful, then there is no need to be afraid, Lao Peng's heart is wide, patted Mao Geng's shoulder and said:

"Maote, with mortars, what are we worried about the cavalry of the Jin Kingdom! If he dares to come, we will destroy him as much as we can. ”

"Mortars, it's still a bit difficult to say, back then, oh, no, it was a later generation, and the Eighth Route Army tried to produce mortar shells in later generations, and it took a long detour, hehe, of course I also listened to Ma Fen. Ma Fen said that the quality of the iron smelted by the clay blast furnace of the Eighth Route Army is not good, and it can only be cast with white cast iron, and the processing performance of white cast iron is very tragic. The cast iron of the Great Song Dynasty was not much better, and the gray cast iron could be made, but the material was still too poor, so the casting of mortar shells could not pass, and then the project was simply stopped. Fortunately, after Lin Lishi came, after all, he is a professional, and he has more methods than me, and now the gray cast iron has passed, and it is estimated that it will not be long before our mortars can be tested. You see, I originally thought that cast iron shells were not difficult, but because the cast iron technology was not up to par, the mortars were difficult to produce. Things in the world are easier said than done. ”

In fact, gray cast iron is not high-tech, Lin Lishi started from the material and annealing, it took more than half a year to basically get it, but the mortar still has the problem of welding the tail, and later it was also borrowed from the soil method of the Eighth Route Army, and the tail was welded by sintering brazing in the furnace, which solved the problem, and it took more than a year to go back and forth. But Lin Lishi was not satisfied with the success of gray cast iron, and claimed to make ductile iron, if he could make ductile iron, it would be great, but in the 12th century, ductile iron was really high-tech, and Mao Geng didn't count on that for the time being.

Lao Peng himself is engaged in technology, and sighed when he heard this:

"It's not easy to climb the tech tree! I also have a deep understanding of this, and even if I tinkered with radio during this time, it seems that it is easier said than done! ”

"Oh, has there been a breakthrough? I've been wondering when I'll be able to use the radio. "Peng Qinfang is a student majoring in electronics, in the plan of the traverser, the radio project is entrusted to him, but the old Peng is also in charge of medical treatment, and some time ago he stayed by the old emperor's side as a health doctor, in view of the radio project has not been reported any good news, so Mao Geng almost has no hope.

"Isn't there a flying pigeon to pass the book!"

"Flying pigeon biography is not safe here in Sakhalin, harriers and eagles are natural enemies of pigeons, Sakhalin Island has a large primeval forest, harriers and eagles are more, flying pigeons are okay to put in other places, it is really not very easy to make it there. If radio can pass the test and can communicate in real time, that is the most practical means of communication. In particular, our military strength is limited, and if we do not rely on information superiority, we will be passive in dealing with the golden soldiers! The golden soldiers can mobilize tens of thousands of troops at every turn, and if we have radio, we can be regarded as having information superiority, and with the help of information warfare superiority, we will be able to fight flexibly and maneuverably, and then we will have a greater certainty of holding Sakhalin Island. Lao Peng, how about it, can the radio be done? ”

"I'm in Lin'an, in fact, I've been tinkering with the radio, in addition to medical and pharmaceutical things, every day is to do manual experiments, before coming, I finally made a spark and ore geophone with some practical value, but this is far from mature, to Sakhalin, you send a few people to me, maybe three or five months, you can make Sakhalin use the radio."

Lao Peng acted like a thief in Lin'an's radio research, because he was afraid of being accused of witchcraft, and secondly, Lao Peng was a person who didn't like to show off, well, it should be said that he was very low-key, so he had been working quietly, and he had even been hiding from Wen Yuan. And the progress of radio is also full of twists and turns, He Chi'an only knows that Lao Peng is tinkering, and there has been no big progress, and then he simply doesn't care.

But the hard work paid off, and after Lao Peng's unremitting efforts, the radio finally achieved something.

When Mao Geng heard this, he was really overjoyed, and immediately stepped forward to have a bear hug with Lao Peng, and then couldn't help but pull Lao Peng away, while saying:

"Why didn't you say it sooner! That's great! Your test device, the alarm or something, you should bring it with you, let's go! Check it out! ”

Peng Qinfangxin said that he originally thought of Sakhalin and then talked about radio, and the set of receiving devices he made was a bit rudimentary, and it was best to improve it when he arrived at Sakhalin, so he could take it out for demonstration, but now Mao Geng is eager to see it, so let's see it.

Peng Qinfang took out a box from under the bed, opened the copper lock, and moved out two smaller boxes from the box, the size of the box was about the same as the box containing Yili milk.

Lao Peng hugged the two boxes like a baby and said:

"In these two boxes, one is a spark announcer and the other is a geophone, let's go, let's go up to your place and take a look. You have a table over there, it looks convenient. ”

Waiting for Lao Peng to put his baby on the table, Mao Geng finally saw the true face of Lao Peng's radio device.

"It's not complicated, and it's not big."

"I didn't say this thing was complicated! The spark announcer is originally simple, you see, this is the boost circuit, here are the two poles of the spark, in fact, it is similar to the principle of the spark plug of the car, this is an inductor capacitor oscillation circuit, this is of course the button of the report. ”

When Lao Peng spoke, Mao Geng nodded vigorously.

Then Lao Peng pointed to the device next to him and introduced:

"This ore geophone is simpler, the key material is this soybean-sized ore, this ore is galena, that is, lead sulfide, lead sulfide and copper pogo pin contact, the function is almost equal to a diode, of course, the performance can not be compared with the diode, but the reception of the telegram is also so-so to meet the requirements. This thing is the ore geophone, as for the code recording wheel next to it, its function is to automatically record the radio waves detected by the ore geophone on the recording paper, and after arriving at Sakhalin, install a escapement with a strip, and it can be automatically recorded. ”

"It's as simple as that? Don't you need a single tube! ”

"No, not one! Lead sulfide and copper pins are the equivalent of diodes. Hehe, it's that simple! ”

"Lao Peng, you are so good!"

"What the! I also thank my university teacher for a story he told during his lectures. My teacher, who was a radio enthusiast when he was in elementary school, spoke proudly of his story about his homemade ore radio, and he told it in great detail, including the use of lead and sulfur to heat it to produce lead sulfide. In the early sixties, the radio was a luxury, and having a homemade ore radio was an amazing appliance. Hehe! As for this spark announcer, there is no one who learns radio that does not know. Of course, it's one thing to know, it's another to do, like making your own capacitors, it's not so simple. ”
