Aside from the identity of the daughter of the God of Wealth, Kong Yuling is also a strange woman in the Republic of China, I don't know why, I just owe a little feeling, Liu Yun quickly thought of Pang Yuyan again, gentle and squeamish, looking like a little bird, which makes people reluctant to give up, although she treats Yuyan as a sister, but when you ask yourself, you really don't feel a little moved.

In just a few minutes, Liu Yun flashed all the women he had seen in the 21st century, in the Republic of China, in the United States, and in China, only to find a problem, he didn't seem to have found the destined woman, and suddenly a shock appeared in his mind, the eldest grandson Mingyue.

Liu Yun also felt that he was very bored, the eldest grandson Mingyue was a fairy, destined to have no chance with worldly love, he had always been a dragon who saw the end and did not see the head, since the Suzhou River in Shanghai, he never saw her again, how could he like her, impossible, but these days, the impression of her is becoming clearer and clearer, as if to make up for the memory that was erased at the beginning.

Liu Yun looked at the sad Master Funakoshi, and was about to get up to find Qingzi, but Funakoe stopped him and asked him to leave as soon as possible, and he would handle the rest of the things, everyone is a man, and they all have big things to do, don't delay big things for a little children's personal feelings.

After some trivial matters in hand are done, Funakoshi and Kiyoko will go to the United Pharmaceutical Factory and return to Japan with special anti-inflammatory drugs, whether it is marriage, recruiting private samurai, or forming the "Ryukyu Restoration Army", they will wait for Kiyoko to come to China next time.

Liu Yun also sobered up, yes, there are two days to go back to West Sichuan County, all the way to the mountains and long roads, the machinery and equipment worth 30 million yen back to West Sichuan, it is destined not to be a simple thing, do not go through the nine hundred and eighty-one difficulties, absolutely not to the end, not to mention that there is still a lot of preparatory work to do, it is indeed not the time to talk about the private affairs of children, and so on the success of the construction of the West Sichuan County Arsenal, when their foundation is first completed, they are still afraid of what Japanese devils.

Liu Yun immediately said goodbye to Master Funakoshi with a fist, and before leaving, he said secretly in the direction where Qingzi left, "Qingzi, in my life, I'm afraid I can't accompany you to the end, I'm sorry, I'm really sorry, but I must make you the queen of the Ryukyus."

When Liu Cheng came out of the Qingshi Mansion, he first scanned around with his brain, he was most afraid of Kenji Tuhihara, full of benevolence and morality, and in a blink of an eye, he ordered the lurking killer to ambush him, or be careful, there was indeed no problem, so he sent a signal to the invisible Yuan Qi'er to "close the team".

After leaving the Qingshi Mansion, Liu Yun walked back to Kong's villa along the Binjiang Road on the north bank of the Yangtze River, looking at the ships coming and going in the river on the way, he had already thought of an amphibious means of transportation, using the newly purchased 300 tons of steel to build a mini dreadnought.

Using the principle of module combination of ant robots, on land, it can be divided into six large trailers, in the water, it can be synthesized into more than 300 tons of cancer warship, "Cancer" means a crab wearing heavy armor, can walk sideways in the water and land, equipped with twelve new tank engines, if necessary, it can provide 9600 horsepower, for the fleet of Minsheng Company, to provide infinite tugboats, the maximum speed is 42 knots, and the economic speed is 12 knots.

In order to prevent the attack of the Japanese army and bandits, the Cancer warship was also frenzied, equipped with six 88mm tank guns, and six M2 large-caliber Browning machine guns, it was really a mini dreadnought armed to the teeth, 12 gunners, 6 machine gunners, 3 communication groups, 12 pilots and other crews, and the captain was of course Liu Yun himself, with a total crew of 35 people.

On the Cancer warship, in addition to Liu Yun, there are some guards of the arsenal, as well as the crew of the Kong family in Wuhan, in the arsenal, he is the commissioner of Nanjing, the second-in-command of the Hanyang Arsenal, and the direct boss of those guards, in the Kong family, everyone knows that he is the quasi-son-in-law of the Kong family, one of the proper heads of the family, so the loyalty of these crew members is absolutely reliable.

As for production, don't worry, the Kong family has its own small shipyard in Hankou, and it is no problem to produce a small boat of three or four hundred tons, but Liu Yun didn't plan to let them build it at all.

39.9 level ant robot, mining / processing speed of 18.89 tons / day, processing a boat of more than 300 tons, only need 10 ants, less than two days, can be processed, the new engine, M2 heavy machine gun and 88mm tank gun are easy to do, but shells and bullets are more difficult to do, Hanyang Arsenal can be produced, but because there is no mass production, they are all processed by the masters, the quality and quantity are a little suspenseful, so they have to produce their own.

Well, to be exact, it is produced by ant robots, but there is a problem, Liu Yun thought about it, what to do with the raw materials, what black powder, yellow powder, propellant and nitrocellulose, etc., he is a liberal arts student and a railway technical school student, he doesn't know chemistry at all, and he doesn't know how to make explosives.

Liu Yun knew that it was a big trouble, and even if the cannon and M2 machine gun were made, they were just for decoration, how to solve the problem of shells and bullets, it was difficult to go to the Hanyang Arsenal and get some explosives back, and he didn't have to think about it to know that in any era, explosives were the object of strict control, not to mention that the director of the arsenal, Qin, would not let the explosives flow out casually.

When someone was in a dilemma, Zhi Brain proposed a way to use compressed air to make projectiles and explosives for shells and bullets, Liu Yun was also brainy, yes, my brother didn't understand physics and chemistry, but when he was a child, he still used an air gun to shoot birds.

What explosives, propellants, is not through the way of impact or heating, so that the powdered gunpowder undergoes a chemical reaction, instantaneously release a large amount of gas, and then the gas propels the bullet or artillery shell forward, and finally when it is close to the target, if it is a grenade, it needs to expand the gas again, that is, explode, so as to achieve the purpose of killing and injuring the enemy.

Liu Yun thought about it, yes, just use compressed air, in a blink of an eye, there is another question, even if the best bird air gun, even if you don't care about the lethality, the range can be 80 meters, you have to snicker, can it be used as gunpowder, according to the experience of fighting birds when I was a child, as long as the projectile flying out of the air gun is more than 20 meters, I generally don't know where to fly, as for the lethality, don't say 80 meters, that is, within 20 meters, it can also shoot through the beverage can.

Why is the lethality of the air gun so low, Liu Yun also had questions before, and he also consulted the master, and the master told him that the reason is very simple, that is, the air tightness of the air gun material is too poor, resulting in insufficient pressurization, it is said that in some foreign laboratories, an air gun that shoots through the human body from 100 meters away has been developed, and there is still a difference between the real gun that effectively shoots more than 1000 meters.

It's too unreliable, no matter how powerful the ants are, they can make effective kills, and air bullets and shells that exceed two or three hundred meters will not help, and Liu Yun's interest will be greatly reduced for a while.

Zhi Brain immediately told Liu Yun that this is not the case, in natural air, nitrogen (N2) accounts for about 78%, oxygen (O2) accounts for about 21%, rare gases account for about 0.939%, carbon dioxide (CO2) accounts for about 0.031%, and other gases and impurities account for about 0.03%, so it is difficult to compress.

However, the ant robot only compresses the most common nitrogen in the air, and then uses the principle of air gun to pump tires to compress the gaseous nitrogen into a liquid, and then compresses the liquid into a solid, and then the solid is preserved by special means to become a solid nitrogen with the thickness of a hair, and then the solid nitrogen is loaded into shells and bullets.

When launched, it can be heated or impacted, so that the solid nitrogen at room temperature can be instantly out of balance, and the volume immediately expands into thousands of times, which is far more effective and powerful than traditional chemical gunpowder such as black powder, yellow powder, and double nitrate explosives, and there is no residue, and it will not burn the barrel and barrel, which is the most ideal new type of gunpowder.

"Moreover, only ant robots can be manufactured, and they cannot be popularized at all", Liu Yun silently added in his heart, thinking about it differently, in fact, this is not bad, he is also a little ant, neither Lao Jiang and Li Desheng have the same eloquence and strategy, nor do they have the ambition to unify China and destroy the sun and swallow the United States, just hope that in the future war of resistance, they can protect themselves, and the army in their hands can have thousands of people It should be snickered.

When he was about to order the start of construction, suddenly Zhi Brain reported to Liu Yun, nearly 200 ant robots, in the past one or two months, the slag and slag under the Guishan Mountain in Hanyang have been almost processed, and a new alloy has been refined, about 1,000 tons, and the remaining slag will be processed within a month, and it is estimated that more than 1,000 tons can be refined.

Liu Yun was shocked for a while, and hurriedly ordered the ant robot to stop refining, because he hadn't thought about it, how to deal with this batch of new alloys, if all of them were handed over to the Hanyang Arsenal, it was estimated that it would still be cheaper than Germany, through his own continuous black whistle, Germany was strong enough, if he got this batch of alloys again, it would be repaid, in case the inertia of history took effect, and Germany was still allied with Japan in World War II, wouldn't this be lifting a stone and shooting himself in the foot.

Or all transported back to West Sichuan County, Liu Yun has some intentions, but there are still some defects, at present, only less than 1,000 tons of steelmaking equipment, it is enough to choke, and more than 1,000 tons of alloy, then do you want people to live, according to someone's own estimates and predictions, through the fleet of Minsheng Company, the steelmaking equipment will be transported to Anchang, it is a limit, really to transport all these equipment to West Sichuan County, it is estimated that it will be until the opening of the railway from West Sichuan County to Fucheng.

Even with the help of ants and smart brains, the railway between West Sichuan County and Fucheng will be repaired for more than 200 kilometers, not to mention steam locomotives and other facilities, just the steel for laying rails will cost 30,000 or 40,000 tons, even if the ant robot is powerful, it will not take a year and a half, don't even think about it, so Liu Yun's plan is to put all the equipment in Anchang County first.

At that time, the guards of the arsenal will first guard the warehouse in Anchang County, and Liu Yunke will take some lighter equipment first, as long as there is a set of steel-making equipment and a generator set, he can set up a steel plant in West Sichuan County, and then use the replication function of the ant robot to manufacture the required steel-making equipment one by one, and he is no longer afraid of the problem of alien technology exposure.

After that, there are two or three more years, you can Sichuan County to Fucheng, Sichuan County to Chengdu, Fucheng to Guangyuan, and Fucheng to Chengdu, etc., the four key railway trunk lines are repaired, and if the Anti-Japanese War has not broken out at that time, you can consider extending to Panzhihua and Kunming in the south, Baoji and Hanzhong in the west, and Chongqing and Guiyang in the east, so as to form a huge and fast rear railway network, and no longer be afraid of confrontation with the Japanese invaders in Wuhan and Changsha.
