"Carrier-based aviation is the key core that will determine the victory or defeat of the sea in the future." Fang Yan, who has been influenced by Germanic culture for 17 years, no longer has that tactfulness and subtlety, but directly puts the core issue in front of the other party, "If your country wants to receive our technical assistance in this vital core area, then you must pay a reciprocal price that is satisfactory enough for us." I think that should be the basis for our cooperation today. ”

Yamamoto Fifty-six's mood was a little gloomy, he was really not used to the other party's way of negotiating with conditions as soon as he came up: the words of the young man in front of him directly sealed his room for return almost completely, leaving only the steps of bargaining like buying vegetables. It is simply impossible to bypass the German Navy, which the other side represents, and directly cooperate with the German aircraft manufacturers: with the rise of Keynesianism in the aftermath of the world war, the days when the capitalists had only money and no nationality in their eyes are gone. Although many of the key technologies in the Western world are still in the hands of private companies, the consequences of transferring them without the permission of the government and the military will be devastating for the company!

After some more temptation, Yamamoto Fifty-six had to give up his plan to use his allies' feelings and **** needs to obtain technology for the white wolf with empty gloves. The other party's unwavering attitude, which was still based on his own rhetoric, was almost certainly instructed by the German navy or the government authorities, and it was clear that he wanted to negotiate terms with him. He exhaled a little unwillingly, and said with a final effort: "If you insist on a technology exchange, then this is really a bit difficult for us. Japan is a successor to the industrial nation, and steel production only exceeded the 1 million ton mark in 1924. ”

A bright smile suddenly appeared on Fang Yan's face, and his expression changed so quickly that Yamamoto Fifty-six couldn't help but be stunned. A sense of foreboding rose in his mind, and his intuition told him that something bad was going to happen next. After a moment, Fang Yan's smile did not decrease. In a calm voice, he said leisurely: "General Yamamoto, your country is currently occupying the throne of the world's third naval power, and of course there will be many technologies in it, which need to be absorbed and learned by the German Navy, which has been oppressed by the Treaty of Versailles for 16 years. For example, your torpedo, which is powered by pure oxygen as an accelerant, is something that is of great interest to the German Navy. ”

Hearing Fang Yan's last words, the originally normal Yamamoto Fifty-six instantly seemed to be struck by thunder and lightning: shock, shock, panic, anger...... All kinds of emotions suddenly filled his heart like a flood bursting its banks. However, out of the instinct of a battle-hardened soldier, Yamamoto forcibly pressed them down with his strong will almost the moment these negative feelings erupted. He inhaled deeply, trying to keep his voice from appearing out of the ordinary: "A torpedo fueled by pure oxygen? This kind of thing has been developed in many countries in the past. However, all of them failed because the fuel exploded when it came into contact with too much oxygen. We in Japan would like to have such a weapon, but we have not been able to overcome this most basic obstacle. I wonder where you heard this completely out of nowhere, saying that Japan already has such something that violates the laws of physics? I have to remind you that you will be responsible if there are any deviations in the reporting in the future. ”

"Why, is it because General Yamamoto is so busy with work every day that he even forgets such an important matter?" Fang Yan seemed to be surprised, but the sneering smile on the corner of his mouth completely revealed his true heart at the moment. Look at the muscle twitching face just a few feet away. Fang Yan smiled unhurriedly and said, "In that case, then allow me to remind you." ”

"As early as the 6th year of Taisho, that is, in 1916, your country launched a research and development project for oxygen torpedoes. Due to the inability to solve the problem of ignition explosion of pure oxygen after fuel mixing. Research has been intermittent and has not been able to make substantial progress. It wasn't until 15 years later, in the 6th year of the Showa era, that an accident finally led to an opportunity to solve this problem: Professor Nagai of the University of Tokyo discovered that if you ignite atomized oil and then blow it into pure oxygen. Although it induces extremely violent combustion, it does not explode. After the research of Shizukuma Oyaki and his team, the phenomenon in this laboratory finally bore fruit three years ago, in early 1933: because it was the year 2593 of the Jinmu period of your country. Therefore, this new torpedo was also named 93 torpedo. ”

Fang Yan took a sip of the tea in the cup and continued to say with a calm expression: "Compared with ordinary thermodynamic torpedoes, the 93 torpedoes with a caliber of 610 mm have excellent performance far beyond the former in any field. It can travel up to 20,000 meters at a limit speed of 50 knots, and its effective range is even more amazing than that of a battleship's main gun; And thanks to the space surplus brought by the use of compressed pure oxygen, its warhead charge reached a terrifying 490kg, which is twice that of ordinary torpedoes of the same caliber, and almost no warship can resist its attack. What is even more commendable is that because the combustion medium of the 93 torpedo engine is pure oxygen, this makes it remove nitrogen and other miscellaneous gases that do not participate in chemical reactions from the gas products after combustion, leaving only carbon dioxide that is easily soluble in water. The vast majority of normal torpedo tracks come from bubbles produced by water-insoluble gases such as nitrogen; The 93 torpedo was almost completely devoid of mine tracks during the voyage, which greatly strengthened its concealment and hit rate. ”

"Since November last year, the surface ships of your country's Navy have been fully equipped with this new torpedo. Since its calibre is too large for submarines and aircraft, your country is currently preparing to reduce it to 533 mm and 450 mm respectively for these two types of delivery weapons. I don't know if General Yamamoto thought of something when I said that? Fang Yan stared at the Japanese lieutenant general in front of him and said with a smile undiminished.

In this process, every time Fang Yan said a word, Yamamoto Fifty-six's face became ugly, and by the end, his face had almost turned black, and the skin and flesh at the corners of his eyes were completely uncontrollable throbbing and twitching. The tumultuous emotions like a storm thundered in his heart, making him almost have the urge to kill the young man in front of him. He really couldn't understand how the 93 oxygen torpedo, which is currently classified as the highest top secret in the navy, leaked to Germany half a world away; Now even a small major on the other side has such a thorough grasp of the entire research and development process of the 93 torpedo and the specific performance indicators, that it is almost like a fire! Thinking of this, his heart couldn't help but burst out with intense anger and pain, and the calm expression that he had held on finally collapsed like a rotten wooden house that had been hit hard, and the whole person became confused and frightened.

"General Yamamoto, you don't need to be too surprised. Do you think that there really is a situation in this world where someone moves a stone on the side of the road and Germany will not know about it the next day? Fang Yan said lightly, his expression was full of unpredictable profundity, "In addition to the full set of technology of oxygen torpedoes, the Type 91 armor-piercing projectile in your country that can greatly increase the probability of hitting a waterborne bullet is also a project that we are interested in. If your country really wants to get our aviation technology, then please use these two subsystems in exchange. ”

Hearing Fang Yan's words, Yamamoto Fifty-six felt an unbearable dizziness in his mind: the Type 91 armor-piercing bullet was also a specialty skill that was classified as a top secret by the Japanese Navy, and now it is also known to outsiders. His hands were clenched into fists, and there was a faint bloodshot of anger in his eyes: there must be someone in his army who leaked secrets, and when he returned home, he would definitely use the tightest net to catch these despicable thieves and rats one by one!

I don't know how long it took for Yamamoto Isoroku to gradually recover from his shock and anger. He slowly picked up the porcelain cup, poured a sip of tea that had already been cold into his mouth, and said in a deep voice: "The 93 torpedo and the 91 armor-piercing projectile are the most valuable research and development achievements of our technicians, and they are unique in the whole world!" We have never thought of exchanging technology with them, which is equivalent to giving away our most beloved wife to someone else in exchange for wealth! Major Jonas, I have known you, and I am as precious to my partner as you are, will you send your wife away for a path to advancement? ”

Seeing that the other party already knew his own details in such detail, Yamamoto Fifty-six was not ready to continue pretending. With a slight movement in his heart, he immediately played the emotional card, intending to use this means to make the young man in front of him show mercy to him.

"General Yamamoto, I don't think your analogy is appropriate." Fang Yan's tone was a little cold, and he retorted without hesitation, "If you say so, then our aviation technology is also a forbidden place that outsiders cannot touch, what are you still doing in Berlin?" I can tell you the truth unequivocally, the German Navy is only interested in these two technologies of your country. Even for aircraft carriers, we have accumulated enough experience in design and use through 10 years of exploration and practice. Therefore, it is difficult for your country to help us in this area as well. ”

Seeing that Yamamoto Fifty-six was still unwilling to make concessions, Fang Yan also applied his most critical dose of fierce medicine, and said hesitantly: "Whether you believe it or not, the news that your country has these two weapons is still known only to the senior management of the German Navy. I only learned this information yesterday from General Raeder. If your country insists on strictly guarding technical secrecy, we will not be able to guarantee that their information will be kept secret forever in Europe and around the world. (To be continued.) )
