On another battlefield, Cheng Biguang was in the V5-012B submarine, silently looking at the scanner, the scribing needle constantly vibrating on the white paper, scanning the surrounding sound wave detection results.

His submarine is the latest to be built, as a test ship, equipped with a new type of underwater sound monitoring system, with an active sounder and a number of sound meters in different positions.

When the submarine is in a lateral position, the monitoring effect of the sound meter will be better, so he has been directing the submarine to sail around the six Ningyuan-class battleships of the main fleet.

The active sounder can emit a special sound that is inaudible to the human ear, and the sound meter conducts feedback monitoring, through echo feedback at at least three points, and then determines the position of the opponent.

This avoids the inherent shortcomings of passive sounders, and can still effectively monitor underwater targets in such a chaotic battlefield.

The destroyers' mines are mainly concentrated in areas between 15 and 30 meters deep, the V5-012B submarine operates at a depth of 40 meters, and the other three V5-B series submarines that are also modified with new systems operate at a depth of 55 meters, or other sea areas.

The needle is still the same as the monitoring result just now, vibrating violently, and constantly drawing a large fluctuation chart.

Cheng Biguang is one of them, the captain of this submarine, and the first military command officer in China to devote himself to submarine engineering.

Through two consecutive feedback scans and almost the same fluctuation chart, Cheng Biguang can confirm that there are indeed two submarines with specifications different from V5 nearby, about 1,000 tons...... This figure is roughly guessed by the length of the target submarine, and he does not dare to be completely sure.

This data is different from the intelligence bulletin he received before, apparently, it is said that Ben has two or even three types of submarines, which is the largest known submarine.

The submarine was operating in an area at a depth of 40 meters, evading the defensive zone of the submarine mine.

As the fifth batch of students of the driving class of Fuzhou Shipmaster Academy and the third batch of admirals to study in the UK, Cheng Biguang's professional and psychological qualities are very good, and he is regarded by Ye Zuqi as a future admiral.

Therefore, Hu Chuyuan transferred him to submarine engineering and served as the first batch of captains of the submarine force.

In a short moment, Cheng Biguang calmly thought about it, first sent electricity to other V5 submarines and Ningyuan through radio devices, and recruited three V5 submarines to maintain a depth of 55 meters at the same time.

The opponent's diving speed is very slow, it should be less than 5 knots, which is basically impossible to escape.

Like a wolf lurking in the dark, he quietly gathered new teammates, flanked him from the northern front, and made the Ningyuan and the main fleet retreat a little away to prevent the other side from firing torpedoes.

Although the submarine should not have the ability to launch torpedoes and aim at targets at such a deep position, Cheng Biguang still hopes to be as careful as possible, a Ningyuan is worth 40 million yuan, almost 45 times the cost of a single V5 series submarine.

Slowly, as if time had stopped, the two unidentified submarines were still trying to get close to the position of the Ningyuan, but they were only groping with the original observations, and there was no doubt that they had neither radio nor sonar systems installed.

It's like two big blind men, trying to play the scene of a blind cat encountering a dead mouse under the water.

Is......?

Cheng Biguang couldn't help frowning, he only felt an incomprehensible feeling, he couldn't imagine that he wanted to fight submarine tactics with such a submarine, and he wanted to defeat China with this little strength?

He thought, Ben is too daring to gamble, right?

Time does seem to stand still, and deep undersea, a bizarre killing and chase is unfolding...... Wrong, this is a real pursuit, the two submarines are just blind submarines, big and big, and the actual tactical value is not high.

As a matter of fact, the submarine is equipped with a radio receiving device.

The reason why the General Directorate of State Intelligence lacks information in this area is that it started its radio technology very late, and only introduced two pieces of equipment from France last year, and increased its orders at the beginning of the year, while the French side has adopted strict secrecy about this, and its own technical level is not as good as that of Germany, the United States, and even less that of China.

First, the radio communication equipment introduced from France was small in number, poor in technology, heavy in weight, small in power, and more unstable, and it did not even have a corresponding wireless communication password in the French language, and it copied the French design, and had to use soldiers who were proficient in French to receive and send messages; Second, this kind of radio communication device is regarded as a top-secret artifact, which is only equipped in submarines, and the headquarters only has a set of switchboards for command, which restricts the use of radio in the entire navy; Third, this is a question of historical fate, and the navy will have only one set of central receiving devices pressed to the command post...... As a result, the antenna was blown off during the first round of shelling, and the ability to communicate with the submarines was lost.

Now, Ijiin Goro can't command submarines at all, and submarines can communicate with each other on their own, but that's communication between blind people and blind people.

Basically, everyone can only ask each other...... Are you dead?

In contrast, China's radio technology in the whole world is a prominent leading position, the world's two major experts in the field of radio, Marconi, Tesla in Shanghai Asia Rich Nation Research Institute, jointly own a wireless communication laboratory, China also relies on this laboratory to train Chen Jinhua, Zhou Chuange, Zhou Chuanji, Kuang Guoguang and other more than 10 experts in the field of wireless communications, under the leadership of Nikola Tesla and Chen Jinhua, China is still conducting theoretical and practical research on the thermoelectronic effect discovered by Edison, The first generation of diodes was developed...... This is the main reason for the technological generation gap between Chinese radio technology and Europe and the United States.

The fate of history is peculiar, and in May 1899, at the same time as he purchased the first radio communication device from France, the diode was invented in the wireless communication laboratory in the rich countries of Asia, and the inventors were the American employees of the laboratory, L. DeForrest and Chen Jinhua.

Since then, it was not until July 1900 that the Fuzhou Modern Telecommunications Company manufactured a new wireless communication receiving device, and before there were no diodes, it was not difficult to send radio signals, but it was difficult to receive signals.

It is said that the Benyi 100-class submarines are equipped with radio transceiver devices, but even so, when the two sides ask, "Are you dead?" they have to pull up the power to the maximum and try to send as many shots as possible.

Basically, they can only send the simplest signals, confirming passwords such as "attack" and "standby".

For all this, Cheng Biguang couldn't understand it, if he knew, he could only say ...... He said he was crazy.

The four V5-class submarines had already confirmed each other's positions and their own positions through radio communication, and through multi-point confirmation, coupled with the assistance of two Shower-class destroyers with balance beam towing active monitoring devices, they quickly and accurately locked on to their opponents.

Two against one, four against two, four against two, four men against two blind.

Deep-water torpedoes were quickly launched, and in order to achieve the effect of one kill, each of the four submarines fired two magnetically guided torpedoes, which could be self-corrected and guided by the principle of magnetism attraction after the launch range exceeded 500 meters.

In order to avoid accidental injury, after the transmission time exceeds 6 minutes, the relay of the magnetic surname mechanism will automatically cut off the electrical circuit and suspend the magnetic surname guidance function.

Even so, the probability of accidental injury is still very high, so there is a principle that must be observed when using this kind of torpedo, that is, your own ships cannot be crossed, but can only be lined up in a column.

Soon, the submarine V5-012B was shaken by a layer of underwater waves.

After the seabed gradually returned to calm, Cheng Biguang immediately activated the sound wave monitoring system, because the aftershocks after the target exploded were too quiet, and it was not until more than a minute later that it was finally determined that the opponent's two submarines were sunk.

Everyone was excited, this was the first time in the history of a Chinese submarine that it had made a meritorious service.

At this time, every submarine commander, including Cheng Biguang, realized a little ...... A second and third chance is just around the corner, and they are constantly expanding their search area, looking for opponents in the depths of the sea.

In addition, more than a dozen Shower-class destroyers patrolled and monitored the surrounding waters, and a number of submarines that barely rushed out and had already left the port in advance were arrested one after another.

In Jinwu Bay, another even worse problem began to emerge, a large number of submarines that had been lurking at the bottom of the sea for more than 35 minutes and could not break through the blockade line were forced to surface one after another.

Watching the submarines sail back to the base one by one, Ijiin Goro was tormented and tormented by himself, and the great dreams of the empire were entangled with the cruel reality, twisting his heart like a poison, and almost tearing his heart to pieces.

When the data of the Great Qing Pacific Fleet exceeded his expectations and intelligence speculation, and appeared in front of him, he already knew this outcome.

The greater tragedy has just begun.

Itishin Goro was well aware that the "Shina Navy" was using a large number of new weapons, especially torpedoes and new warships, and that the warships produced by the company and built by France were not at all comparable to the warships of the "Shina people."

The same main gun between 12 inches and 12.5 inches, the opponent can easily penetrate and sink the battleship, and even if the main gun hits the opponent, it will not be able to produce a fatal blow.

The gap between the two sides is already all-round, the stability of the main guns, the rate of fire, the penetration of firepower, especially the time-delayed armor-piercing shells used in large quantities by the Pacific Fleet, even France does not have them, so far ...... It was the first time that Goro Ijiin knew that there was a country where industrial production and use could be made, rather than just staying in a laboratory.

In addition to the six Ningyuan-class battleships of the Pacific Fleet, including the flagship, the rest of the main warships used steam turbine units and mixed-fuel boilers, and even pure heavy oil boilers.

In terms of hull design, whether it is armor protection design, stable balance and anti-sinking ability, acceleration maneuver ability; In terms of firepower system, whether it is the shooting hit rate and stability of the main gun, the coverage and firing speed of the secondary gun, and the penetration ability; In terms of tactical execution...... The all-round gap is simply impossible to bridge.

Battleships, cruisers, destroyers, frigates, torpedo assault ships, torpedo assault boats, multipurpose patrol boats, gunboats...... This is an all-round battle of naval strength, and in all aspects, Yuben is almost at the bottom.

Both sides are constantly sending assault boat clusters to attack the opponent's main warships, and the Pacific Fleet can quickly annihilate the assault boat group with a large number of destroyers and a large number of secondary artillery systems, but the ship is unable to do this, and ships are constantly sunk by assault boats.

In terms of torpedo technology, the gap between the two sides is even more obvious.

On the land side, a division of the 14th Division, using all the fortifications at its disposal, was easily crushed by an equal number of integrated divisions, and as soon as the land battle lasted four hours, the four lines of defense of the 14th Division were torn apart one after another, and the defenders were completely lost.

The 15th Division of the Japanese Army, which rushed to the rescue from the Kadena area, was easily intercepted by the strength of a regiment, and was immediately torn up and cut by the new troops who followed behind.

The gap in the Army is also all-encompassing.

Now, Ijiin Goro suddenly had an epiphany...... The reason why the previous Ryukyu garrisons were easy to deal with was simply because they were more like decoys, and what they encountered in front of them was the main force and real strength of the "Shina people".

With that eternal discrimination against Chinese in his heart, Ijiin Goro had to admit that he was the loser of the Second Sino-Chinese War...... It is destined to be the book again, unless France officially declares war on China, in which case it ......!

"In that case...... It doesn't seem to make sense anymore! ”

Ijiin Goro looked up at the sky indifferently, thinking in his heart that the hot-blooded and loyal imperial generals he loved had all been broken, like countless young flying cranes, one by one in mid-air and falling into a muddy swamp.

On this ruined fort, Goro Ijiin, known as the last admiral of the Honmoto, slowly drew his saber and aimed the tip of the knife at his lower abdomen ......!

He didn't want to die, he just felt ...... As a samurai of the Great Shoben Empire, it is better to die in this glorious place than to live in a place where there is no hope and great future, rather than to live in a time when Asia is ruled by a group of lowly and ignorant Shina people.

At least, he had fought valiantly against the people of China for the future of the empire and his children.

Until this moment, he still firmly believed...... The battle will continue, although it will not be in his generation, but there will come a time when Ben will defeat China and become the hegemon of Asia.

At that time, the sun flag of the Great Empire will surely shine in the whole of Asia, and it has the largest land and resource ...... in Asia.

At that time, Shina was no longer a nightmare in everyone's heart.

Go for it, my Matsuji...... I'm sorry, but I can't let you live in the arms of a powerful empire.

At the last moment of his life, Goro Ijiin thought of his son, who was only seven years old.
