The top brass of the People's Party welcomed the change in Japan, and a country focused on the struggle for the distribution of domestic productive forces would not generally choose the route of external expansion, unless it was really an unworkable path. It will take at least several years to be judged. As for whether Japan at that time would become stronger as a result of the rectification in the past few years, the top brass of the People's Party did not care. It has taken more than 20 years for the BJP to focus on science and technology and the development of the productive forces, and now the road has not only not narrowed, but has become wider and wider. If Japan loses this path within a few years, it will surely fail. Such a failed state is not destined to be too powerful.

Of course, a large part of the self-confidence of the top brass of the People's Party comes from Chairman Chen Ke's satisfaction with the current technological development in China. Since the leaders of the People's Party can express their satisfaction, the comrades are convinced that China is on the right path.

Chen Ke was naturally satisfied, believing that China would be able to make a big profit during the Great Depression, as evidenced by the Soviet precedent. In fact, there was more to the fish than Chen Ke wanted. China has struggled to catch up with the second industrial revolution, and many breakthrough technologies before World War II have not been accumulated, but people in this era have not thought of how to combine these technologies and break through in a new direction.

People in this era did not expect the future direction of technology, but Chen Ke has seen it with his own eyes. One of the biggest difficulties for Chinese industry is the problem of accurate measurement. If you want to machine high-precision parts, you must have higher-precision machine tools. Chen Ke was deeply impressed by one thing, he heard his family say that in the past, a batch of equipment from the United States and Germany was imported from China's railways, and the accuracy of these equipment was required to reach five decimal places, while China's measurement accuracy at that time was three decimal places. At that time, China's factories were called big, which meant that China simply did not have the ability to determine the true size of the parts it produced.

It's easy to split a millimeter in two, and it's not too difficult to divide a millimeter into ten. It is absolutely a big problem in industrial technology to divide a millimeter into a thousand and a thousand into a thousand. How do you determine whether the accuracy is 1/10,000 or 0.5 per 10,000? Or is it a more precise number? None of this would be possible without precise measuring instruments. So one of the first few industrial sectors established by the BJP was weights and measures.

No matter how much you invest in measuring instruments, they will not be enough. The industrial department of the People's Party spent nearly 30 years on this, accumulated a lot of technology, tried countless experiments, and it was not until the Great Depression that it knocked on the door of those second-rate measuring instrument factories in Europe and the United States. When the BJP took over these factories, it wanted everything, not even the scraps of paper on which the words were written.

The accumulation of hundreds of years of machining knowledge in Europe and the United States is really not a joke, and those tricks and ideas are really exquisite. Even the People's Party itself has been working hard to accumulate, and after really seeing the number of roads of other people's old industrial powers, Chinese technicians are also amazed.

However, many design ideas in Europe and the United States that cannot be realized due to technical conditions have strengthened China's industrial sector, and the fact that Europe and the United States cannot do it does not mean that the People's Party cannot do it. Quartz clocks, electron tubes, transistors, lasers, these technologies combined with traditional precision measurement technology have played a great role in breaking through the bottleneck of the old precision measurement technology in China.

By at least 1935, there were machines in Chinese laboratories capable of achieving an accuracy of one hundredth of a millimeter. With high-precision production capacity, two-axis linkage machine tools and three-axis linkage machine tools are also being developed frantically. Once these machines can be completed, the machining accuracy of high-precision components can be improved exponentially.

For example, the reactor sold to Japan is not very accurate, and in order to prevent leakage and other problems, it is necessary to be stupid and coarse. Technically speaking, stupid and coarse things are extremely uncontrollable in terms of expansion rate. The uncontrollable expansion rate will inevitably increase the possibility of interface leakage under high temperature and high pressure. In order to avoid this possibility, the production system must be meticulous to the level of extreme perversion. After all, hydrogen leaks in a high-temperature and high-pressure environment, and something will happen.

The material has gone up, the processing accuracy has gone up, and the seemingly simple two pipes are screwed together, and a sleeve is added so that it will not leak. Machining accuracy is not only used in high-temperature and high-pressure equipment, but also large-scale production lines require high-precision components. A production line is often hundreds of links, each link has a little error, and in the end it is a problem whether the production line can be started. As for the quality of the product, there is no need to think about it. Even in modern times, line commissioning is a terrible job. Not to mention the level of 1935. Therefore, once the production line is started, it is the longest possible operation, which puts forward extremely high requirements for materials, and a bearing runs continuously for more than ten days, which is really a high-tech business.

It took a lot of thought and a lot of experimentation to make this simple thing. Each experiment requires a cost, and the amount of money spent on the experiment is much greater than the amount of the vehicle can be measured. This is the accumulation of industrial countries, and it takes decades of perseverance to do so.

Therefore, China does not care about Japan's technological development at all, because all the intelligence collected by intelligence officers points to one thing, and the Japanese industrial sector has no intention of building production lines at all. Historically, Japan's production line came into existence after a large amount of technology was imported from the United States, and it was a project that the Japanese industrial bureaucracy made with great determination. Today, Japan's small family-run businesses are the absolute mainstay. Great industrialization is like a floating cloud on the horizon for them.

The large production line is the key to determining whether the homogeneous product can be produced in large quantities, just like the steampunk-style bullet production line of "Lord of War", which looks very rough, but can produce tens of thousands of bullets per day. These bullets are placed in Japan, which requires more than ten times more manpower and dozens of times longer to be produced. This is the strength of a truly industrialized country. If I could produce one bullet, I would be able to produce 100 million of the same bullet.
