The Pixiu is good, and Li Guang doesn't feel bored about staying in the cabin. Began to propagate to the soldiers that what was the value of sinking a warship and what was the value of sinking a merchant ship. How much can they contribute to the country's resistance? Although these elements have been addressed many times in the two specially equipped instruments. However, Li Guang felt that it was still necessary to deepen the understanding of the fighters again and again, because after all, they were fighting overseas, and many fighters still had some doubts about whether the Naval Resistance Army was not fighting in China's waters.

Li Guang discovered a flaw in the Pixiu, which did not have any entertainment facilities. For troops on land, this is nothing, but for claustrophobic submarines it is a big problem.

There are two clerks on the Pixiu, who are equivalent to the political commissar of the industrial army or the priest of the American army. In addition to propagating patriotism, its work is to educate the fighters on cultural learning. There was no entertainment involved for the time being, so Li Guang had no choice but to call Ji Keliang over, this is a master of the music department, and singing a few songs can naturally enliven the atmosphere.

Under the leadership of these two, the morale on the submarine was maintained very well. Li Guang decided to install a gramophone on the Pixiu next time.

There is another point, Li Guang didn't come up with a way to break his head. That's the problem of going to the toilet on the submarine. When it was first designed, Li Guang was very careless and simply made the simplest toilet. When the ship is stopped, it is proposed to go and pour. Dozens of people are on a submarine, and if they are forced to hide underwater for ten or eight days, this is a big problem. It's winter, and the smell is bearable, but if it's summer, it's a big problem.

Another problem that can be solved is the temperature in the submarine, when it is close to the equator, the submarine is hot and only wears short sleeves, and when it reaches the northern part of the Pacific Ocean, it is wrapped in cotton clothes. Li Guang offered to install air conditioning, but the simple peasant warriors were not interested, they thought it was too extravagant. I even think that that thing is only worthy of the chairman and can enjoy one or two. Of course, the air conditioners in this year are very large, not advanced, and more importantly, they consume electricity. At a critical moment, one kilowatt-hour of electricity can get a submarine out of danger.

Generally speaking, the surname of Pixiu can make Li Guang satisfied, but there is a little flaw, that is, the noise is still loud. The noise of the engine is almost earth-shattering, and it is difficult to hear even the shouting volume in the engine room, and the tail engine room is usually closed. Thanks to the use of a double hull, there is water isolation between the inner and outer hulls, and the noise from the outside is not excessive, but it is far from quiet. Li Guang can only hope that the engine he designed should be quieter in the future.

However, in order to ensure the smooth command of the command cabin and the engine room, Li Guang decided to temporarily install a few indicator lights. Microphones simply do not guarantee the timely transmission of commands. There are many problems like this on the Pixiu, and they can only be discovered during actual voyages and battles, and in just one month's voyage, at least fifty or sixty areas for improvement have been discovered. If you want to truly improve Pixiu, there is a long way to go.

Even though there are many problems, Li Guang is still in a happy mood. On the North Pacific route, the merchant ships of Yuben were not escorted by warships at all, and the sneak attack was like hunting, easy and pleasant.

Slowly, Li Guang figured out one of the biggest characteristics of submarine warfare, and he had to be patient. For example, in the North Pacific route, the battle ended in half an hour, but in order to find the target, the Pixiu took six full days.

This kind of live-fire training is of great benefit to the improvement of the fighters. After two battles, this group of soldiers already had the appearance of veterans.

It's just that there are still gaps in some aspects. For example, the Navigator. The Pixiu submarine got lost on the way home.

After easily sinking the four merchant ships, the Pixiu waited for a few more days, but could not see a single merchant ship pass through, so it had to return. At that time, the location of the Pixiu was too close to the mainland of the United States, only 100 nautical miles, and it was very unsafe. Strictly speaking, the Pixiu had already entered the territory of the United States, but the Americans were obviously not very concerned about the sneak attack on the merchant ship, and during the next few days of searching for prey on the Pixiu, they did not find a single American [***] ship at all.

In the North Pacific Ocean in winter, it was cloudy and there was no sunshine. Relying only on the magnetic compass is no longer enough, and can only sail in the general direction.

Ten days later, there was still no sunshine, and Li Guang ordered the ship to stop, and it could no longer run blindly on the Pacific Ocean like a headless fly. You have to rely on a sextant to calibrate it.

According to estimates, in ten days, the Pixiu traveled about 3,500 nautical miles, which should be close to the equator, but according to the temperature, it is obviously wrong. It's not cold, but it's definitely not warm.

However, Li Guang was not in a hurry, and the Pixiu was filled with diesel fuel after the first battle, and it was able to travel 16,000 nautical miles. With the current amount of oil, even in the Arctic Ocean can run to Antarctica. Half of the world is only 20,000 kilometers, more than 10,000 nautical miles. Now in Uruguay, there is Yuan Ran in charge, the little girl is very capable, everything is managed in an orderly manner, and in terms of business management, Li Guang is ashamed of himself. Even Uruguayan businessmen discussed with Yuan Ran about any business, like a housekeeper. Li Guangneng put forward some opinions on construction and forward-looking plans, but it does not mean that his management ability is superb, he just has the advantage of being ahead of his time.

Li Guang suddenly came back to his senses, how did I think of Yuan Ran, shouldn't I think of Su Zizi? Don't?

Li Guang retracted his mind and considered another question. The pickup number went to Guangxi under the leadership of Zheng Xuechang. After a year, Li Guang received news from Xu Zhan.

Since Xu Zhan broke up with Li Guang in Nanjing, he used the food and medicine left by Li Guang to go back to his hometown to organize a group of about 100 volunteers.

In the Battle of Nanjing, his small team was incorporated into the troops of Chairman Chiang's favorite general, Hu Zongnan. Since then, he has joined the anti-Japanese army.

Subsequently, Xu Zhan continued to fight with Hu Zongnan, and the result was to fight one battle and lose another. In the Battle of Lanfeng in Henan. Hu Zongnan's First Army faced the main force of the 14th Division of the Yue Army, Xu Zhan fought bravely to kill the enemy, but finally due to poor equipment and poor training, in the fierce battle with the Yue Army, more than half of the casualties of one battalion were killed. Later, Xu Zhan's troops were urgently replenished with more than 1,000 people in the local security regiment in Henan, and two days later there was a fierce battle, and more than half of the casualties were again lost.

Unexpectedly, in order to block the offensive of the Yue army, Chairman Chiang dug the embankment of the Yellow River at the mouth of the garden, causing millions of people to be displaced. And the hometown of more than 1,000 brothers of the security regiment who Xu Zhan was replenished in the Battle of Lanfeng is in the Yellow Flood Area.

The logistics of the army in the country were extremely disorganized, and the brothers of the security regiment were killed or wounded without even a single notice. The father and the villagers were displaced, and the relatives did not see anyone alive or dead, and finally found Xu Zhan. Facing the eager gaze of his father, Xu Zhan was speechless.

These people have not only lost their relatives on the battlefield, but also lost the land on which they depend for their survival in the great waters, and their lives are already precarious.

Xu Zhan is a soldier, and he may still have some ability to lead soldiers to fight. But in the face of the survival of more than a thousand people, there is nothing that can be done.

At this time, Du Yuesheng's subordinates found Xu Zhan and spread the news of Li Guang. Xu Zhan knew some of the situation in Uruguay, and in the predicament, Xu Zhan pinned his only hope on Li Guang. So he sold his family property, traveled thousands of miles with nearly a thousand old and weak, begged all the way, and arrived in Guangxi in three or four months.

Li Guang is not afraid of these thousands of people, he has territory now. Robinson Island is a desert island that can't feed many people, while Easter Island has a lot of land, so there should be no problem in feeding some people. But most of these people are women and children, as well as the elderly, and it is difficult to find a job for them. If you do industry, you don't have culture, you don't have technology, it's too difficult.

As a native of Henan, Li Guang was well aware of the great famine that occurred in the Central Plains a few years later. He was very willing to do something for his father, but he didn't expect that Henan's economy had begun to deteriorate now, and the number of hungry people was already quite terrifying. He had read the novels written by Liu Zhenyun and the "1942" directed by Feng Xiaogang, in which the description of the famine was eerie. Thinking of this, Li Guang felt that since he had come to this era, he should not only make some efforts for the cause of the Anti-Japanese War, but also do something for his hometown fathers.

Li Guang was in a daze, when suddenly the alarm sounded. After a burst of chickens and dogs, the hatch of the submarine closed, and the Pixiu dived rapidly.

Warships were spotted on the surface of the ocean.

As for which country's warship, in the gloomy winter, I didn't see it clearly. Less than ten nautical miles, this distance is likely that the other side has already discovered the Pixiu submarine. Just now the submarine was sailing on the surface of the sea.

No matter which [***] ship it is, it cannot be detected, this is the principle of submarine warfare. The Pixiu immediately switched to electric power, dived to 100 meters and began to sail at a low speed.

Li Guang ordered, and the propeller slowed down to ten revolutions.

The silent speed of the submarine underwater navigation is 20 revolutions of the propeller at six knots. At this point the speed is slower, only about three sections, but the sound is quieter.

All the members of the submarine were kept in the quietest state, and the fighters who were not on duty were resting on their beds. Non-combatants are also in a state of silence.

There is no doubt that at this time, Ji Kelian has become the most important player. At a distance of ten nautical miles, if you use a telescope with a diameter of 15 centimeters, you can definitely see the Pixiu clearly. Even on such cloudy days.

Just now due to the operation of the submarine's diesel engine, Tikerian's listening was affected. Although it is not the quietest time now, in the deep sea, avoiding a lot of noise interference, Ji Kelian's ability can definitely play very well.

After a while, Ji Kelian said: "Port side, about 4.5 nautical miles." ”

This shows that the other party has definitely discovered himself. There is only one way in front of Li Guang, hoping to escape before the opponent arrives.

So the order was increased to thirty revolutions. Li Guang has a lot of trust in Ji Keliang, and he can barely hear the opponent's voice from this distance, so even if the opponent has a master like Ji Keliang, if the sonar level is the same, he will definitely not be able to hear the voice of the submarine.

The Pixiu's large-diameter propellers are designed to avoid noise. This is also the product of Li Guang's insight and guidance in later generations. In this era, no designer has ever been so refined, and most designers are still having a headache with the sound of diesel engines, and they can't think of such subtleties at all.

Pixiu does a pretty good job in many aspects of the subtleties. It's not a technical issue, it's a conceptual difference in design. Other submarines have railings and some cables on their hulls. The Pixiu simply didn't have these things, and even the two deck guns had streamlined shields, which greatly reduced drag and noise.

Judging from the listening device, the opponent's speed was quite fast, and it only took less than ten minutes to reach the previous position of the Pixiu. At this time, the Pixiu had just run less than a nautical mile.

Li Guang ordered again, and dived to 150 meters, with the same speed and course.

It is estimated that the opponent did not find the direction of the Pixiu, and after a while, Ji Keliang said: "It must be a Fengfeng-class destroyer, the sound is very similar." It's going around in circles right now. ”

Li Guang knew that this was the standard way of anti-submarine for destroyers. Circling at high speed can avoid opponent strikes, and it is also possible to determine the opponent's position based on sonar. The good news is that the opponent is circling in a circle, centered on the position just now, but drawing an inverse circle. At least this first lap is hard to get above the pickup.

It's just that Li Guang doesn't know how big a circle the opponent will go around, and it only takes more than ten minutes for the destroyer to draw a circle with a diameter of two nautical miles.

Ji Kelian has a super ability to distinguish the subtleties of sound, and now that Ji Keliang is basically sure that he is a warship, then the next thing is a life-and-death battle.

Li Guang has completely calmed down. When your life is threatened, you should not put your expectations on your opponent, hoping that your opponent will not reach the top of the submarine's head in circles, which is obviously too passive.

Li Guang decided to speed up his rush out. Just gamble, and the devil can't hear his voice for two nautical miles. So the Pixiu immediately accelerated to a speed of ten knots.

At a speed of ten knots, you can run a little and a half nautical miles in ten minutes. At that time, the devil will go around to the closer point, and the distance will be one and a half nautical miles, and it will not be so easy to hear himself.

Li Guang gave the order, but now his palms were full of cold sweat. After all, due to the lack of intelligence, it was difficult for Li Guang to know the sonar surname of the warship.

Ten minutes later, the results came in. Li Guang passed the exam, the Devil Warship continued to circle around, and the Pixiu continued to break away.

By the time the warship had once again circled to its nearest position, the Pixiu had already run out of three nautical miles. The devil didn't seem to have much patience and casually dropped two depth charges. Expensive depth charges only blow up a few small fish more than a finger long. The little devil can use it to make sashimi.

When the Pixiu ran out of five nautical miles, Li Guang slowed down. Quietly float up and stick out the periscope to observe. At a distance of five nautical miles, no matter how careful the little devil is, I am afraid it will be difficult to find a periscope more than two meters above the water surface on the vast sea.

With such a vast Pacific Ocean, you can get lost and bump into the devil, Li Guang is not afraid at this time, but excited. If you deliberately search on the ocean, you may not have such an effect. Now that the host and guest are shifted, it is Li Guang's turn to sneak attack the devil.

After this encounter, the submarine once again formed a new regulation, as long as it goes to sea, it must remain in combat condition at all times.
