Therefore, it is useless to just master theoretical knowledge such as the structure and principle of direct injection engines. If you really want to diagnose and repair direct injection engines, you also need the assistance of practical hands-on experience.

However, this kind of practical hands-on experience knowledge is scarce in Daxia's education system. Daxia's universities or colleges generally do not focus on teaching this kind of practical hands-on knowledge.

If you want to have this knowledge, you can only go out to work and search for information or make blind guesses when you encounter such problems, and then analyze the causes afterwards to gain your own practical hands-on experience and knowledge.

As for why Daxia’s education department does not teach these practical hands-on knowledge.

The reason is that direct injection engines are too complex and there are too many possible failure phenomena.

If I really want to teach you in detail how to repair this direct injection engine, do I still need to teach you the other components and systems of the car?
And if you really want to teach, you need to create a lot of faulty direct injection engines.

Otherwise, if the teacher only talks about the fault symptoms and the causes of the fault, the students will definitely not be able to remember these things and will not have any practical experience.

However, if we want to produce so many direct-injection engines to increase students' practical diagnostic experience, the cost of the teaching equipment is too high and the school certainly cannot afford it.

But now if we have a virtual world, all of this is no longer a problem.

After all, in the virtual world it’s just a waste of computing resources and electricity.

Compared to purchasing many direct injection engines, the cost of using the virtual world to accumulate practical hands-on experience is much cheaper.

The most important thing is that the wool comes from the sheep. The cost of using the virtual world must be borne by the students, not the school.

In the end, the school did not have to spend a penny on experimental teaching equipment, and the school was naturally very happy.

Although the students seem to have borne the cost of using the virtual world and seem to have suffered a huge loss, they actually made a lot of money.

Because everything has been secretly marked with a price. After all, the cost of purchasing the school's experimental equipment will actually be spread over the tuition fees.

At this time, the school does not need to purchase expensive experimental teaching equipment, so there is naturally no reason for the school to maintain such high tuition fees. At this time, students naturally make a lot of money.

Therefore, if the virtual world is really created, the role it can play is really huge. It is no exaggeration to say that it can change the world and the history of human development.

And if Daxia vigorously supports knowledge infusion technology and virtual world technology, then Daxia's development speed in one year may be comparable to the development speed of several years.

In the end, it only took a few years to achieve a level where friendly countries were stunned and exclaimed that the speed of Da Xia's development was simply unscientific.

Because knowledge infusion technology can help people remember everything they see, and the virtual world can help people gain rich practical experience.

By combining theory with practice, we can eventually cultivate backbone talents with rich theoretical knowledge and practical experience in a short period of time.

If such key talents only account for a small part of Daxia, it would not mean much. The influence they can produce is quite limited due to their small number.

But if the 13 million employed people out of the 7.4 billion people in the world, excluding infants, pregnant women, students and retired elderly people, all mastered rich theoretical knowledge and practical experience.

This power is enough to shake the world and change everything!

After all, knowledge is power, knowledge is productivity, and knowledge is wealth!
If all the 7.4 million employed people in the country could master a wealth of theoretical knowledge and practical experience and become highly qualified industrial workers or scientific researchers who are excellent in the world, how could the productivity of Daxia not explode on a large scale, and how could the growth rate of national strength not soar like drinking Red Bull? !

Under such circumstances, with the explosion of productivity, various technologies will surely usher in major breakthroughs.

In the end, perhaps it will only take 5 or 10 years for Daxia's technology, equipment, instruments, materials, etc. to catch up with the entire West.

After all, having more people means you have more power, especially when you have 7.4 million highly qualified industrial workers and scientific researchers who are among the best in the world.

With so many high-quality talents, perhaps even without Daxia doing anything, many foreign companies will come to Daxia to establish their own high-tech factories or R&D institutions.

After all, Daxia has a large team of high-quality industrial workers and scientific researchers. Overseas companies naturally want to come to Daxia to establish high-tech factories and R&D institutions, so that they can become stronger and stronger.

And because of the rapid development of Daxia's productivity and technology, Lin Feng will eventually achieve his ultimate goal of building a space exploration spacecraft to explore the solar system and the Milky Way in a shorter time.

Of course, it is not an easy task to transform all 7.4 million employed people into high-quality industrial workers and scientific researchers who are excellent on a global scale.

Because the world is dynamic, it is normal to be jealous of others doing better than you.

This truth applies to everyone, from small companies and neighbors to large countries.

If you want to make money and develop yourself peacefully, others will definitely be jealous and unwilling to accept your success when they see how well you are doing, and will try to make things difficult for you.

So although the future prospects are bright in theory, the process may not be bright. On the contrary, the development process may be bumpy.

Of course, even if others try their best to trip them up, Lin Feng believes that Da Xia will get through it and will persevere.

After all, there is a saying that goes, it is better to have something yourself than to have it from your parents. If you don’t want to be controlled by others, then work hard to make yourself strong.

Only in this way can we resolve those troubles and make them dare not continue to have evil thoughts and do bad things through our upright strength.

Of course, let’s not talk about the future for now. Whether it is brain-computer interface chips or knowledge infusion technology, these are all things of the future.

If Lin Feng wants to make the virtual world and knowledge infusion technology truly practical, he needs to meet many prerequisite technologies.

Otherwise, those technologies are just castles in the air and can only be used on a small scale and cannot be deployed on a large scale.

As for what is the advanced technology?
The main issues of this prerequisite technology are the high-speed communication network outside the brain-computer interface and the computing power of the computing center.

After all, the computing power of current chips is limited, and the size of the brain-computer interface chip implanted in the brain is destined to be too large.

So no matter how powerful you want the brain-computer interface chip implanted in the brain to be, it is simply impossible to achieve.

In this case, the only thing that can be done is to submit all computing tasks to external computing centers for processing through high-speed communication networks.

Therefore, if the problem of high-speed communication network and computing center computing power is not solved, the brain-computer interface chip will be nothing but a waste. (End of this chapter)
