If the traverser doesn't have a Du Niang with him, or is a cattle-level scholar himself, he doesn't know the key technology of the old world and doesn't know why, or he only knows the name and principle, and he doesn't know the technical details at all, it's a normal thing. Especially for half-hung military fans like Luo Zhengdao, who have never worked hard to study knowledge and specific numbers, and only know some knowledge for their own interests, it is polite to say that they know a little bit of knowledge.

For example, Luo Zhengdao must know what the structure of a computer is, and he also knows that the core technology of hardware is to make a CPU made of monocrystalline silicon, and the principle of an electronic computer is binary, which does not mean that he can build a computer, and it is almost the same to get an abacus, and it is enough to study mechanical computers, and the development of steam engines is probably the same.

It seems that in the old world, there is no strange school that will teach its students, "500 Essential Common Sense of Climbing the Science and Technology Tree You Must Know After Crossing Over", "How to Build a Great Empire from Scratch", "Principles of Formation and Operation of Guerrilla Warfare and Other Illegal Armed Groups", "Building Anti-Politics. One Hundred Questions on the Armed Base Areas of the Prefecture", and so on, which can be called bizarre courses. Because of this, storing the scattered and fragmented knowledge of the old world in the mind of Zài Luo Zhengdao can provide him with some guidance and a long-term blueprint.

To solve the difficulties and obstacles from the conceptual sketch to the practical process, except for patiently climbing the science and technology tree and repeatedly trying and making mistakes again and again, there is no shortcut, so the right way in the world is the vicissitudes of life!

At this time, the black metal object that appeared in front of Luo Zhengdao's eyes, two people tall, in the empty factory, was the first steam engine sample in the New World. Theoretically speaking, it can output a strong power equivalent to thirty horses when it runs at full strength, but the stability of the operation of this machine is relatively poor, and it has broken down three times in a row within an hour of Luo Zhengdao's inspection, and the average smooth operation of each time is less than ten minutes before there are various failures, and it has to be shut down for maintenance, and the whole working time is not as long as the maintenance consumption.

Needless to say, such a lame demonstration of the steam engine disgraced Faul Chopin, who said apologetically:

"Your Majesty, it's a pity that you have seen such an unreliable opportunity."

Seeing this, Luo Zhengdao, who had been prepared, smiled indifferently, expecting that the development of new technologies without a foundation would be very bad, and the farce in front of him did not exceed his expectations, and said with a smile:

"Hehehehehe, it is inevitable that new things start with failures and setbacks. Record the reasons for each failure and the solution for the next improvement, and when you can't find room for further improvement, this machine will have practical value. ”

The rocket engine, which was first applied to surface ships by Luo Zhengdao and has been widely promoted, is very advantageous as a battleship afterburner system, and it is too luxurious as a conventional power. Assuming a radical overhaul of the warship's structure, such as removing the unsightly sails, the prospect of developing a steam engine would be much better than the study of a rocket engine. Rocket engines, which can be used repeatedly for a long time, only appeared in the old world on the luxury of the space shuttle, and finally were replaced by disposable spacecraft due to economic reasons, poor cost-effectiveness, and uncontrollable risk factors.

Luo Zhengdao asked himself that he did not have the wisdom beyond mortals, he would rather set his goal lower, it was enough for the steam engine-driven blades to drive the warship forward, and the rocket engine could continue to do its current job, these are two things that go hand in hand.

"How fast can the sample run on an ironclad ship?"

Luo Zhengdao's question was what Old Fore had been waiting for, any new technology would be used in the military first, no matter what purpose they were originally developed for, this was determined by the aggressive nature of the intelligent race. Just as civil wars between the human forces in the New World are rare, not because they have learned to work together, but because more wars have been fought against aliens.

Voul Chopin stroked the cold cast-iron casing of the steam engine with his hand and replied:

"The installation of six steam engines can drive the test ship to 5 knots, and the output power is still too low, and I promise that we can achieve better results in the future."

Hearing this, Luo Zhengdao couldn't help frowning, such a speed of development was greatly behind his expected value, and according to this calculation, he could not expect the steam engine to be on the ship for several years.

The long-term expectation of the fall of the main continent and the turbulent recent situation superimpose on each other, and the effect is not as simple as one plus one equals two, but a relationship of geometric multiples.

From a long-term perspective, the ensuing unexpected changes and bad news will inevitably cut off the supply chain of traditional filament yarns in the new world, and at the same time continue to raise people's psychological thresholds. In the later stage, the price of magic cloth, which completely relies on artificial silkworm rooms, will inevitably soar to a staggering and terrifying price driven by the speculation and hoarding of merchants, as well as the rigid demand of the market.

Despite the high manufacturing cost of steam engines and the unstable operating performance, Luo Zhengdao was able to see the broad development prospects and unlimited application range of steam power from the historical experience of the old world, and made this investment as soon as possible.

Suppose that the magic cloth is a year-old and withered herbaceous crop, and there is not much room for further improvement after countless improvements, the current steam engine like a child's toy is undoubtedly a woody plant that can eventually grow into a towering tree year after year, and one day will one day thrive over time and become a sexist that makes people look up and sigh. Some self-proclaimed clever people often like to laugh at new things that seem to be out of the ordinary, such as complaining that a budding sapling does not grow as tall as the surrounding weeds, and this kind of wrong rigor cannot be offset by no matter how much you estimate. Too much can only be verified by time, unless the observer's eye can see through the years and glimpse the real picture of the future.

"Alright! Continue to work hard to improve and try other solutions, and the development of Project 1 cannot be stopped. ”

Luo Zhengdao's optimistic statement relieved the researchers, but they soon understood that this was a means to continue to increase the weight, and this was another way to exert pressure. If you use any resources at your disposal, I only need to speak in the tone of the result, and the subordinates will no longer be able to shirk the responsibility for failure, they must think about one thing clearly, and they have received such strong support, if they face the result of failure again, then whether they should go to seppuku or eat guns, which way of death will be more painful.

"Yes, Your Majesty, we will do our best."

Nodding, Luo Zhengdao followed and said:

"How's Project Three?"

Faul Chopin suddenly patted his head and said:

"Ahh Please come with me. ”

Together with several of his subordinates, he got into a carriage and rushed to the secret dock, and in the heavily guarded fully enclosed dock, Luo Zhengdao saw the phased results of Project No. 3, which was the first time he saw the real thing except for a brief schematic diagram.

A new warship with an extremely strange appearance in the eyes of ordinary people was lying in the dock, its length was too discordant compared to the extraordinary width of the hull, and the whole ship seemed to be squeezed by someone from the ends to the middle, and even the bottom part of the ship was a gentle arc.

Since the high-ranking priest invited by Luo Zhengdao from the Yaling Empire used magic to repair the blind eye, Old Fu Er can no longer be called the one-eyed dragon, and at this time he introduced it with great earnestness:

"Your Majesty, according to your instructions, the draft of this ship is two yards, the maximum speed is twelve knots, and the key parts of the hull are protected by armor, although it is not as strong as the defense of the ironclad ship, it is much stronger than that of ordinary warships."

The offshore waters close to the main continent and the water environment in the rivers are not suitable for seagoing ships with too deep drafts to enter the activities, and the structure of ordinary inland flat-bottomed ships is too fragile, and the battleships transformed from transport ships will be beaten into a colander every minute under the threat of battery fire, and they are very ineffective as professional warships. For this reason, Luo Zhengdao ordered the Wake Reef Shipyard some time ago to test and develop special warships for operations in shallow water environments of rivers and lakes, and this kind of shallow gunboats with shallow draft and armor protection are the main force in the next stage of guerrilla warfare against goblins.

The appearance is too short and thick, and the warship that can be called the spokesperson of the new world generation of Tu Fei Yuan has relatively poor seaworthiness in the ocean, and is not suitable for running to the open sea where the wind is high and the waves are fast. The problem is that there is only a short voyage from Qiongzhou Island to the main mainland, which is limited to the use of this kind of coastal battlefield environment, and the shortcomings of individual performance can be ignored.

Luo Zhengdao, who has accumulated rich experience in naval warfare, carefully examined this new warship and asked:

"Is it ready for mass production?"

"Well, on average, one can be built in a month."

Hearing this, Luo Zhengdao, who shook his head again and again, expressed his dissatisfaction and said:

"Slow down, let's speed up some manufacturing! We need a lot of shallow gunboats, the more the better, and you'll have to push them to speed up production. ”

As a die-hard fan, Faure Chopin never doubted Luo Zhengdao's instructions, but he also had a dilemma, and said in a hurry:

“…… But there's still a problem! ”

As soon as he heard this, he turned his head to look at Old Fuer, Luo Zhengdao suddenly laughed, raised his hand and patted him on the shoulder, and said:

"Next time you have something to say, don't be taboo about so many boring etiquette."

"Okay, Your Majesty. Is it okay for us to have too few skilled workers to produce shallow gunboats with all our might, and not enough merchant ships and ironclads under construction? ”

The shipbuilding industry is a manpower, technology, and capital intensive industry, and even in the old world, it has not been able to completely get rid of manual processing, and it does not require human participation, and the whole process relies on automatic mechanized shipbuilding, which is still a science fiction vision. The difficulty of building a ship with a machine is much higher than that of a car, and the large number of irregular solder joints in the hull alone is enough to make people scratch their heads, and this complexity makes the role of skilled workers constantly magnified. The role of skilled workers in the quality of industrial products should not be underestimated, and the most typical example of this is the reconstruction of the aircraft carrier Shinano with the Yamato-class battleship No. 3 during World War II in the Old World.

It is known that this giant ship with a displacement of 70,000 tons suffered several fish after being launched. The mine sank, compared to two battleships of the same class, which could take a dozen * and fish. Ray, who continued to hold on to the water for an hour, did not look like a factory made of the same series of products.

If you delve into the reason, the reason is nothing more than that the Pacific War drained the manpower of the foot basin chicken, and the skilled workers in the shipyard were all conscripted and pulled to the front line as cannon fodder.
