After Lin Yang created his trump card, the insecurity in his heart was slightly relieved.

I was planning to go out for a walk and take a rest, but when I stood at the door I suddenly realized that I had been researching for several years. If there was no result, would my family members become suspicious?

Lin Yang thought it was possible. If it were someone else, it wouldn't matter, but he had always been able to come up with something new, improve something, or achieve a breakthrough in his cultivation after each retreat.

There was no way to hide the fact that I was conducting research. If I didn't produce any results, I was afraid people would start to doubt me. Then my trump card would be exposed.

In order to protect my own trump card, I still have to do more research. I have to come up with some research results to fool people.

"What kind of research?"

Jade slip? A message slip, a query slip, or some other kind of slip?

No, no, I have asked for experimental materials several times in the past few years, and they are all metal-related. They must be metal-related.

Regarding metals? You can refer to the mortal world in the books "Management" and "Mecha Science".

Um - car!

People in that world did not use horse-drawn carriages, but mechanical power.

Since the demonic disaster, there have been no horse-drawn carriages. Transportation has become much more difficult. If that civilization's carriages were developed, it would be much more convenient.

When discussing the history of mecha, the book "Mechaology" mentions the principles and design drawings of the car. Hmm, if we could use this as a basis for modification, then... Hmm, like this, like this. So that's how it works. What a genius design.

"Beep—Random mission released: Spirit Stone Powered Car.

Mission: Transform the car into a spirit stone powered vehicle and perfect the entire spirit stone powered vehicle to be suitable for use by cultivators.

Reward: Activate system function: Sky Eye - Radar.

Now that even the system tasks have come out, Lin Yang naturally has more motivation to research.

Lin Yang fell into research state again.

The key to the transformation is to change the gasoline engine into a spirit stone engine.

With the master-level refining level, it was not difficult. Lin Yang quickly locked onto the water and fire Tai Chi formation in the Tai Chi formation. This solved the problem of turning the gasoline engine into a spirit stone engine.

Then there are other aspects: the body, that's easy, the tires, that's not difficult either, the interior design, that's readily available, the steering system, that's also readily available...

A month later, through magical modifications, a spirit stone powered car was finally created.

The task didn't show as completed. Only the first sentence turned green, while the second sentence remained in red.

"In other words, the system defaults to the fact that this gasoline engine-modified spirit stone-powered vehicle is only suitable for ordinary people? Not for cultivators?"

After thinking about it, it's true

"Without technologically advanced roads or anything like that, a four-wheeled vehicle like this is definitely not suitable for cultivators.

Besides, without protection, wouldn't it be like a moving coffin for cultivators? Transportation still needs to be considered for combat. During the Demonic Calamity Era, transportation between different base cities is not safe."

With the above analysis, Lin Yang found the maglev car again and began to modify it.

This anti-gravity chassis can be constructed using a levitation array. The levitation array can actually be understood as an anti-gravity array. However, levitation arrays are generally used for the construction of fixed buildings, objects, and facilities, such as floating islands and floating signs, and are rarely used for mobile objects or tools.

This is easy to understand, because the suspension formation needs to be adjusted specifically to one place. Once it moves, the magnetic field changes, the suspension formation will not match, and it will get out of control.

This is a difficult problem for technological civilization to create a maglev vehicle. There are two solutions to the problem.

One is an artificial track, which can keep the gravity magnetic field corresponding to the anti-gravity chassis unchanged, so as to achieve high-speed movement in a magnetic levitation state.

Another approach is to expand the area covered by the levitation array. The larger the area, the smaller the interference. Combined with a control system, the effects of magnetic field fluctuations can be completely offset. If this were expanded to encompass the entire planet, then driving across the entire planet would be a surefire way to prevent loss of control.

Lin Yang naturally chose the second option. The first option was too wasteful of manpower and material resources. Moreover, it was not realistic to lay tracks outside the base city.

Lin Yang spent decades in the virtual space and finally expanded the corresponding area of ​​the suspension formation to a radius of ten kilometers.

Combined with the control system, it can barely be used.

Then there was the protective formation. This was simple, as it was readily available in the world of cultivation. A protective formation that could withstand the demonic level was quickly chosen, and then adjusted and optimized before integrating it into the car body.

The magnetic levitation vehicle loaded with the ability to resist demon soldiers is finally completed.

Then the experiment loaded the magnetic levitation vehicle with a protective formation that could resist the demon-level defense, but this level of protective formation was too complicated, and with Lin Yang's current level of formation, there was no way to complete it.

This formation is extremely difficult to optimize, and the optimization limit is only about 30 meters. The car body is only 3 meters long, a full ten times difference, making it impossible to integrate it into the car body.

Thirty meters, wait...

If it is thirty meters long, it can be transformed into a large truck, specifically for transportation between base cities.

If it is 30 meters long, it can carry more cargo. People who work in transportation should be happy to accept such a huge truck.

Moreover, the chassis of the car has become larger, and the corresponding area can be expanded accordingly. In this way, the car can be driven faster and more stable at low speeds.

It's just too large to be easily defended. However, if the defensive formation is at the level of a demon lieutenant, its safety shouldn't be a problem at all. It could even be used as a mobile fortress, capable of both attack and defense. Okay, this is it.

Lin Yang continued his research and this time, he quickly developed a truck that could withstand the demon commander level. Furthermore, because the chassis was larger, the radius of the car increased from 10 kilometers to 100 kilometers.

After completing this truck, Lin Yang felt a sense of accomplishment as he looked at the three spirit stone powered vehicles.

At this point the system task is also completed.

"Beep—Complete the random mission: Spirit Stone Powered Car, get the reward: Activate the system function Open Eyes—Radar.

ps: Sky Eye - Radar: It can detect the number of cultivators and monsters within a radius of ten kilometers, their levels (from low to high, corresponding to six light spots of red, orange, yellow, green, blue and cyan. Purple light spots are other descenders.) and their distribution situation, 100 merit points per quarter of an hour.

limit:

1- The upper limit is the host's Great Realm. Beyond the host's Great Realm, it cannot be detected. However, it is displayed as a black dot representing invincibility.

2- It will only be unlocked when you are on the battlefield or behind enemy lines, or when the cultivation world enters battle."
