As for Li Chun, who left, he couldn't see this very cute face.

Pushing open any door, he is now transforming the world again.

At this moment, he was on an island called Kuna.

This island is a four-island archipelago along with the three large islands of Fukurushima, Kasamatsu and Jodori Island, as well as about 30 islands densely scattered around it.

That's right, this is the elevated neon island city, which belongs to the game world "Quartet on the Other Side".

Li Chun's purpose for coming here is also very simple, that is, the unique equipment of this game world is Grav-Shoes.

However, this time, Li Chun did not directly arrive at the factory that made Grav-Shoes to obtain the technology.

Mainly because the development of Grav-Shoes is based on the fact that scientists from this world have discovered a particle that defends gravity.

And whether this particle exists in other worlds, is unknown.

Therefore, the first thing Li Chun needs to do is not to obtain technology, but to buy a pair first, and then wear it back to the Kexue world to see if it can be used.

After trading an item through the door, Li Chun took the cash and bought a pair of regular men's Grav-Shoes.

After testing his ability to fly, Li Chun came to the conclusion that with a little bit of control skills, he could easily control the direction of flight.

It's just that every time you take off, you need to shout Fly a little bit of what, at least Li Chun doesn't like this voice-activated switch.

Pushing open any door and returning to the world of Kexue, Li Chun couldn't wait to test the pair of Grav-Shoes.

If you use it, it is no problem, that is to say, this shoe is not limited by the changes of the world in the world of Kexue.

Of course, this is not to say that there are anti-gravity particles in the world of Kexue.

It's that the particles in these shoes are not affected by the changes in the world, and that's it.

But this is enough for Li Chun.

Yes, so that Li Chun can include this equipment in the exchange list.

As for manufacturing, why make your own equipment that even the general public can afford?

When necessary, just buy dozens or hundreds of pairs and put them away.

And the result of the test is that it can indeed be used, that is, Li Chun's list of exchange items can be added to an exchange item.

As for the other piece of information that Li Chun said before, it actually has nothing to do with this.

This is just a piece of equipment that Li Chun suddenly thought of because of that information.

That's right, what Li Chun wants to obtain is indeed the manufacturing materials of anti-gravity manipulation equipment.

But the world in which this material is located is not in "The Quartet on the Other Side", but in the world of "Princess Principal".

This world is set at the end of the 19th century, and the stage is London, the capital of the Kingdom of Albion, which is divided by huge walls from east to west.

The anti-gravity material, refined by scientist Dr. Kaiber from an anti-gravity material mine, has the effect of masking gravity and creating a truly gravity-free space around it.

Then, the scientists of the kingdom invented various machines that floated in the air by studying how to use the heat energy generated by the steam engine to manipulate anti-gravity matter.

Li Chun firmly believes that compared to steam heat, electric heating is much better in that aspect.

Therefore, as long as this kind of material is brought back to the world of Kexue and has been proven to be undisturbed by the changes of the world, it can still be used, it will be very meaningful.

At least the construction of the Helicarrier is no longer a fantasy that exists only in the future.

And compared to the big guy of S.H.I.E.L.D. that relies on nuclear energy to drive the anti-gravity engine into the sky, anti-gravity matter in the true sense has more advantages.

After all, one also needs to consider its own weight, while the other only needs to consider the affected area of gravity-free space.

Judging from the volume of the anti-gravity material flying battleship made by the Kingdom of Albion, if it can be controlled by replacing it with the electric heat generated by nuclear energy, the volume of the space carrier that can be manufactured can be increased even more.

Of course, there are two prerequisites, the first is that the anti-gravity matter is not affected by the changes of the world and fails, and the other is that the amount is sufficient.

Compared to these two points, the manufacturing technology of anti-gravity material manipulation equipment is not so important.

Because we know that thermal energy is the key to control, we only need to carry out targeted tests in the future.

In fact, if it weren't for the time to save some time in developing equipment, Li Chun wouldn't even have to get the manufacturing drawings.

After all, there are inventors in the Kexue world who are smart enough, such as Dr. Asasa and the like, who will definitely be able to make the equipment that Li Chun requires.

Of course, Li Chun can also find equipment masters from other worlds.

Therefore, compared to the anti-gravity matter itself that is refined, nothing else really matters.

Of course, it doesn't mean that this is the only thing in this world that can be valued by Li Chun.

For Li Chun, valuable things are not limited to objects, but also people.

Yes, Li Chun is still eye-catching to the spy personnel in this world.

Of course, this doesn't mean that you have to be included in the house.

Rather, in 19th-century London, there was only one word in the mainstream of high social circles, and that was elegance.

But any normal woman who can enter the social circle, regardless of her morality, at least in terms of elegance, is absolutely deadly.

And this kind of elegance exuded in the bones, in the modern world, it is definitely a temperament that can make people look sideways, after all, elegance will never go out of style.

Therefore, if anyone has a maid or housekeeper with this temperament, it must be a display of heritage.

Because of this, Li Chun planned to take a few people back by the way.

And the specially trained spies in this world are not only elegant, but also have a lot of skills.

Although it is only stronger than ordinary people, Ke Xue's world is still ordinary people at most, and with these people to assist Mute and Inoue Orihime in dealing with people, not only does he have face, but he can also save a lot of worry.

After all, every qualified spy, at least in the social area, there is no perfection, only more perfect.

After coming to the world of princess standards, Li Chun subconsciously looked up at the sky.

Night had fallen, and although the snow had not yet fallen in the sky, the atmosphere was very cold.

Taking a slight breath, the unusually obvious smell of smoke and dust in the cold air made Li Chun frown.

It seems that this alternate world of London is the same as the real world of 19th-century London.

"This bad environment, staying for a second more is a murder to yourself, it seems that you need to speed up and get things done here, and then leave this world quickly."

After muttering a word, Li Chun took out a mask from the storage backpack and put it on, and then continued to hide his figure and walked towards the Queen Mayfair School not far away.

This is the school where the protagonist group attends, and Li Chun plans to use the anti-gravity equipment in the hands of the spy princess in the protagonist group to find out whether the anti-gravity matter will be disturbed by the changes in the world.
