This is indeed a difficult choice for people to decide, the power of a torpedo with a small caliber is weak, this is certain, but the safety of the 65 torpedo is indeed not easy to guarantee, with the Kursk unlucky ghost in front, it is very uneasy to use.

"In fact, there are many improvements to the Type 65 torpedo, such as the TT5-1 type, which is now the best, not only replaced with safer Otto fuel, but also installed a wire guide device, but one thing is that this thing is a new product after all, first, the price is more expensive, and secondly, it takes time to customize." Sablin looked at Yang Feng's appearance, hurried to him and said in a seductive tone.

"Other data, I'm going to have a long enough range." Yang Feng suppressed his excitement and said.

"The range can reach fifty kilometers at fifty knots, and the range is even longer at low speeds, and as for the power of the warhead, needless to say, five hundred kilograms of high-energy charge is almost equivalent to eight hundred kilograms of TNT, even if it is enough to blow up Nimitz."

"Very good, very good, I want this, get me five first, not six." Yang Feng said with a smile, this thing should be enough to deal with the Yamato, and besides, the Japanese haven't made the Yamato yet! Playing dead Nagato is not a piece of cake.

"But I have to change it to a surface launch." Yang Feng added.

"There's nothing wrong with that, but I'm curious, why don't you get a real submarine?" Sablin is clearly not satisfied with the current level of arms sales.

"Where am I going to find someone to drive? Besides, a Kilo is so expensive, and I can't afford it. Yang Feng said that he didn't really mind the price, mainly because he couldn't find someone to drive, after all, this kind of submarine was too sci-fi for the Republic of China.

"You can buy small submarines, and if you are worried about the quality of the crew, then I can help you buy small submarines from North Korea. For example, their Shark class, which does not pour a displacement of 300 tons, carries two 533-mm torpedo tubes, and is very advantageous in shallow waters offshore. Sablin said.

Yang Feng touched his chin and began to hesitate, it's actually quite good to get a thing like this, first of all, the level of skill will not be too advanced. I believe that the Xiaoyang family does not have this ability, and if the Tian'an incident is true, then it is enough to prove that this thing has a certain strength, and the price will not be too expensive, and it is quite good to get two ships in Bohai Bay.

"I can consider it, but I need to inspect it myself, and if I'm satisfied, it's not impossible to buy four or six." Yang Feng said.

When the arms issue was solved, Yang Feng was waiting for the Russian technicians. He also started to deal with some other things, one is some information on his investment, Ye Qian collected all the information on the US stock market in the thirties and forties for him, a large part of which was paid for by some research institutions in the United States, and stored on the hard disk Yang Feng had time to read it slowly by himself.

The key thing that needs to be solved is the data of rare earth production, because California's rare earth mines are mainly fluorocarbonite, but Yang Feng is not interested in producing things like cerium and lanthanum at the price of cabbage. At least it has to be neodymium, europium. Praseodymium, these are more expensive, of course, the production of these things is also very technically demanding.

However, there is enough money to sprinkle away, this problem is not difficult to solve, and at this time, the production technology of various rare earth metals is no secret. Moreover, what Yang Feng wanted was not the latest technology, but the older he was, the more he liked it, and he quickly bought all the information he needed from universities and research institutions at home or abroad.

With these well-established technical materials, plus the research of those university professors over there. It shouldn't be difficult to produce the rare earth metals you need yourself.

Half a month later, the Russian technicians, together with the Buran torpedo that Sablin bought for him, arrived at the same time, but the TT5-1 torpedo still needed some time, and it was estimated that he would not be able to bring it back this time.

In addition, a batch of portable anti-aircraft missiles purchased from China also arrived, a very classic avant-garde 2, this thing is undoubtedly an unsolvable big killer for aircraft in the thirties and forties, with the SA-N-11 anti-aircraft missiles in the Kashtan system, AK630 close defense guns, enough to provide all-round protection for Yang Feng's armed yacht.

During World War II, Japan's air-launched torpedoes had a range of two or three kilometers, and with the clumsy body of the torpedo attack plane, it was a dream to break through such a triple protective network in the distance, medium and near.

In the next nearly a month, Yang Feng was as diligent as a primary school student who had just entered the campus, under the guidance of Russian technicians, learning the installation, use, and maintenance of the Kashtan system and the Buran torpedo, of course, only some of the most basic things, these two systems were not something he could play alone in a month, he only needed to ensure that these two systems were installed on his own ship, and the rest could only be studied slightly, and then translated various manuals into Chinese and brought back.

More than a month passed, and everything was finally ready, he closed the dock again, and then returned to the Republic of China with a shipload full of various goods, this time crossing the sea east of Shanghai.

In this way, he had to face a trouble, he could not go to Shanghai, he brought too many things that could not be made public this time, Shanghai was not his territory, and if it was exposed, it would be easy for others to covet, so he could only go back to Tianjin Port and land, and there were still more than a thousand nautical miles from here to Tianjin, and he had to face the possible harassment of Japanese warships.

"What if it becomes a British warship?" Looking at the vast sea, he couldn't help but show a wicked smile, and under his instruction, the beautiful woman's head quickly transformed into a British cruiser that he had seen in Shanghai, and then drove straight to Tianjin at a high speed of fifty knots.

After dawn, he hurriedly lowered his speed to maintain 25 knots, ran at such a speed for a day, and after nightfall, he soared to 50 knots again, and entered the mouth of Dagu at midnight, where he re-transformed into a merchant ship and arrived in Tianjin overnight, and then hurriedly called the garrison, and the first brigade of security dispatched a whole regiment, with an unprecedented arrogant attitude, according to the boss's instructions to quickly empty the wharf, not to mention the idle personnel, even the customs officers were pushed aside.

"Mr. Yang, what do you mean by that?" A customs official said with a displeased face, although they did not have the habit of checking Yang Feng, they were inevitably a little emotional when they were treated like this.

"This ship is loaded with self-propelled guns ordered by the National Government, who is responsible in case of an accident?" Yang Feng glared at him and said, as soon as he said this, the official immediately shut up.

After the dock was blocked, there was a loud roar of engines. A modified Volvo heavy truck with all markings removed was driven directly out of the ship by Yang Feng, and this truck was loaded with the Kashtan close-in defense system and a blizzard torpedo.

"No one is allowed to approach this ship until I return, hear it clearly. Do you understand? Yang Feng, who was sitting in the cab, said to his regiment commander with a solemn face.

"Understood, boss!" The regiment commander said with an American-style military salute in a dashing manner.

Yang Feng nodded with satisfaction, and the Volvo FH16 heavy truck, which was equipped with six pairs of load-bearing wheels, went straight to Beiping under the escort of twenty Wranglers equipped with M2 machine guns.

After arriving at Fengtai Industrial Park, the heavy truck drove directly into the division headquarters of the security division, and then stopped on the big playground. One by one was dumbfounded.

"Oh my God, boss, what kind of truck is this?" Howard screamed like a collapse, although he came from the United States, where the automobile industry was the most developed in this era, such a huge truck was still unbelievable.

"Regardless of what kind of truck it is, gather the soldiers at once, and surround it as fast as possible with a wall as high as it is, and leave no door." Yang Feng said to Sun Liren.

The thing pulled up a chair and sat in front of the car. Then make a pot of tea and sit here and supervise it. Seeing that the sappers used a four-meter-high fence to enclose the truck inside, and then called his guards from Jinyuan.

"Old Wu, from now on, you will take twenty brothers to set up tents and live here without my orders. No one is allowed to approach it. Yang Feng said to his guard elder Wu.

"Anyone?" Lao Wu looked at Sun Liren and Howard and the others, and asked with some uncertainty.

"Yes, anyone." Yang Feng replied with certainty.

"Got it!" Lao Wu said.

Sun Liren and Howard looked at each other, knowing that Yang Feng had never kept anything secret from them, even those self-propelled guns. Yang Feng has never forbidden Howard and these American officers to contact, including his extended-range shells, which also made Howard and others very moved, this time even they couldn't touch this truck, which shows how important this thing is, and they can't help but look solemn.

"Brother Fumin, Colonel, it's not that I don't trust you, brother, but this thing is too important to me, and second, they are not army weapons and have nothing to do with you, so I have to do this." Yang Feng was slightly apologetic, turned around and said to the two of them, he is not a leader, and he has always treated his subordinates as brothers.

"Yang, there's no need to explain, like you said, we're brothers." Howard shrugged and said that he knew that Yang Feng was mainly saying this to himself.

"This time I brought a new army weapon, which is still on board the port of Tianjin, but this kind of thing should also be kept as secret as possible, because as far as I know, the Russians are also developing this kind of weapon, and I don't want them to target it." Yang Feng then said.

"What's that?" Sun Liren asked suspiciously.

"Brother Fumin, do you remember that we had a weapon called a swarm of bees in ancient times?" Yang Feng said with a smile.

"You mean the kind of box-packed rockets that fire repeatedly?" Sun Liren said suspiciously.

"yes, what do you think it would be like to take that old weapon and put it on a modern face? What happens when you replace the black powder incendiary with a modern incendiary agent, and the body made of bamboo and wood with steel, then equip it with a high-explosive warhead, and then fire a salvo at the same target in an instant? ”

"It's going to be hellish fire, you're not going to tell me you're bringing this weapon, are you?" Howard said in a trembling voice that it was clear that he also knew something about Chinese history.

"Yes, I gave it a name called Whirlwind." Yang Feng said with a smile.

An hour later, in Tianjin Port, when Sun Liren and the others looked at the rocket launchers pulled out of the cabin, their expressions immediately became a little strange.

"Yang, is this your mysterious weapon?" Howard was visibly uncomfortable with its rudiment.

"Colonel, there are some things that you can't just look at, I believe that after seeing its power, you will fall in love with it as much as you love a beautiful woman." Yang Feng said.

As he was talking, an officer of the Security Brigade ran over and saluted and said, "Report to the boss, Chairman He has arrived." ”

It is clear that the soldiers of the Security Brigade meticulously carried out Yang Feng's orders. No one is allowed to approach the docks, not even Ho Yingqin.

"Ah, hurry up and get our treasure away, and don't let Chairman He see it." Yang Feng said and quickly asked his subordinates to cover the rocket launchers with tarpaulins, and then directly dragged them to Beiping with a wrangler, and then went to meet He Yingqin.

"What are you doing?" He Yingqin said with some dissatisfaction.

"Chairman He. Tianjin is full of Japanese spies, and now they must know that I brought self-propelled guns, and you also know that these guys are crazy, what if any loyal samurai under His Majesty the Emperor came over and threw bombs on my ship? Yang Feng said with a smile.

He Yingqin snorted coldly, he didn't believe Yang Feng's nonsense! What this guy just pulled away must be some new good thing, of course, he doesn't care much about it now, he cares about the twenty-two self-propelled guns belonging to the Central Army. It is said that after Yang Feng left, Chairman Jiang was concerned about his whereabouts more than a dozen times.

Twenty-two self-propelled guns, under his gaze, drove out of the cabin one by one, before the bald guy had already selected a group of cadets from the Zhongyang Military Academy, trained by Yang Feng's chariot company, and now they were all brought over by He Yingqin, and these people took over from Yang Feng. Then he got on a special train heading south, along with the cannonballs attached to Yang Feng. Shipped directly to Nanjing.

After all these artillery pieces were transported away, He Yingqin breathed a sigh of relief, and then said to Yang Feng angrily: "What did you bring with you something unsightly?" ”

"Chairman He, what you said is not right, I have something to see people." Yang Feng said with an aggrieved face.

"Hmph, you drove a giant truck back to Beiping overnight. Along the way, the houses on the side of the road trembled, do you still think that no one will know the way? And what are you walking with a tarpaddle, not afraid to see people? ”

"It's nothing good, it's just a few weapons newly developed by our Yanhuang Laboratory, let me bring it to Peking to test it. If it works, can I forget about you? Yang Feng said.

Sending He Yingqin away, Yang Feng supervised here again, until all the goods were unloaded from the ship and then loaded onto the train to Beiping, and then the cargo ship was sailed out of Dagu at night, and then transformed back into the box cargo and returned to Beiping.

As soon as I woke up the next day, I was pressed back to bed by Margaret, who had heard the news and ran back from Shanghai, and after a period of upheaval, I got up refreshed, patted the little goblin's buttocks and said, "Why didn't Sakura come together, was it bullied by you!" ”

"She went back to Japan, I don't know what Lu Dao is going back to do, you left just a few days after you left." Margaret pounced on his back and writhed like a snake.

Back to Japan? Yang Feng felt a little surprised, you must know that she has never taken the initiative to return to Japan, and she was urgently recalled by Yan Qi, whatever! Anyway, everyone knows her identity, it's just a tool used to win her over, although she never played a big role, but the Japanese are not so cute as to let her leave her.

After getting up, Yang Feng came to his office with Margaret in his arms, and as soon as he entered, he was stunned for a moment, and now there was a girl about twenty sitting in the position of Xiaohui outside, with short and capable hair, who was lying on the table to sort out documents, and raised his head when he heard the sound of the door opening, and when he saw Yang Feng and Margaret's appearance, his delicate face turned red, and then he quickly stood up and said, "Mr. Yang, you are back." ”

Yang Feng then remembered that he already had a new secretary.

"You're Han Caiyi! Last time your uncle told me, you seem to have graduated from Peking University, right? Yang Feng hurriedly let go of Margaret's hand on her waist and said with a kind smile on her elder's face.

This is his new secretary, Wang Chuanming's niece, Peking University Chinese Department just graduated, Xiaohui left to tell him about it, Yang Feng thought that he really needed a secretary by his side, so he agreed.

"I just graduated, and I don't understand many things, so I ask Mr. Yang for more advice." Han Caiyi lowered her head and said softly.

"Okay, if there's anything you don't understand, just ask me." Yang Feng opened the door of his office and walked in as he spoke, and Margaret looked back at Han Caiyi maliciously before entering the door.

Yang Feng was in no mood to care about her careful thoughts, not long after this guy sat down, he was called to the industrial park by Sun Liren's phone, and these officers couldn't wait to see the power of rocket artillery.

"You have to find a suitable place to do this, this thing has a range of more than eight kilometers, and it is not suitable to test it in Beiping!" Yang Feng said with a frown.

"What if we go to the front line in Doron?" Sun Liren said.

This suggestion is good, you can not only test the artillery, but also beat the Japanese, and this thing can be transported on the plane, Yang Feng immediately became interested, and a group of senior officers flew straight to Duolun with a rocket launcher, and Margaret also followed.

After Yang Feng left, there has been no large-scale battle between the two sides on the Duolun front, and both sides know very well that the other side is not easy to deal with, so they are accumulating strength and preparing to launch a thunderous attack after the beginning of spring.

After arriving in Duolun, Sun Dianying and the others were also very uninterested in the new weapon brought by Yang Feng, this thing is indeed very inconsistent with the image of a big killing weapon, it looks like twelve steel pipes tied together, if you want to say that this thing is a cannon, no one will believe it.

"Brother Yang, you said that this thing can fight seventeen miles, which is farther than the range of the Japanese mountain artillery?" Sun Dianying lay in front curiously, tilting his head and looking, no matter how he looked, he didn't look like he could fight seventeen miles.

"When did I lie to you? The barrel of this thing plays a directional role, and what is really useful is the shell, which has no recoil, let alone a barrel, and can be shot without a barrel! Yang Feng introduced with a depressed face.

"Can you get out without a barrel? Are you kidding me? No one believed it anymore, Zhang Tingshu shouted on the side.

"If you don't believe me, I'll show you how!" Yang Feng looked around, there was a hut not far in front, this goods called a soldier, took a shovel to pile up an inclined plane on the ground, then picked up a cannonball and put it on it, adjusted the angle and loaded the sight on the aiming hut.

"You're not trying to tell us that this cannonball can fly on its own, are you?" Zhang Tingshu leaned over and looked at Yang Feng, who was holding the battery and preparing to ignite the fire, and said with an incredulous expression. (To be continued......)
