After Doraemon and Nobita left, they waited about three to five seconds before the drawer where the space-time machine was parked opened again, and the first thing that appeared was Doraemon's round head, and his face was full of smiles.

After jumping out of the drawer, Doraemon raised a white pocket in his ball-shaped hand at Wang Zhi, and said happily: "Wang Zhi, the four-dimensional pocket you want has been bought, just in time for the big discount in the future department store, and I have bought a lot of other things, all in your pocket." ”

After speaking, Doraemon handed the pocket to Wang Zhi.

Taking the four-dimensional pocket, Wang Zhi held it on his body and gestured to see where it was better, and asked Doraemon, "What did you buy?" ”

"This is the invoice, look at it yourself!" Doraemon took out a long invoice from the four-dimensional pocket and handed it to Wang Zhi.

Wang Zhi took the invoice and looked at it a few times, looking at the things that Wang Zhi wrote on the first page of the list, such as any door, magnifying light, shrinking light, adaptation lamp, time towel and translation konjac, and then he didn't look carefully, he was fiddling with the four-dimensional pocket in his hand, and after looking for a long time, he didn't find the authentication port of the pocket, so he asked Doraemon: "Doesn't this pocket have a recognition function?" So how can I be certified as its owner? ”

"The controller in the pocket is in the pocket, and if you think about something, it will appear in your hand."

Hearing this, Wang Zhi immediately put his hand into the four-dimensional pocket, and then thought about identity authentication, and sure enough, it didn't take long to touch something, Wang Zhi immediately took it out, it was a display full of Doraemon world style, and there was an operating table under the display, with only an arcade-like joystick and one and two buttons, one was a switch, and the other was a OK key.

Wang Zhi immediately pressed the switch, the screen lit up all of a sudden, and two lines of words appeared on it, that is, two options, one is identity authentication, and the other is appearance selection, Wang Zhi chose identity authentication, pressed the OK button, and three faces appeared on the screen, namely Nobita, Doraemon and Wang Zhi, Wang Zhi chose his face, pressed the OK button, and immediately completed the identity authentication.

And just when Wang Zhi wanted to see what the shape choice was, a submarine-like thing suddenly appeared on the floor of Nobita's house on the wall, and several people in uniform suddenly jumped out of the submarine: "Don't move, we are the space-time police, you are suspected of illegal smuggling......"

Wang Zhi didn't listen to the next words at all, he was now like the underworld who was trading du products but was discovered, and there was only one thought in his heart: the strip is coming, hurry up.

Wang Zhi immediately hurriedly stuffed the identity authentication machine into the four-dimensional pocket, and then crawled into the space door that had been open next to him, and the whole process took no more than a second.

Escaping into the space-time corridor, Wang Zhicai felt that his fast-beating heart slowed down slightly, but when he saw that there was a space-time policeman who wanted to rush into the space-time corridor to arrest him, his heart hung again, and when he saw that he hit the space door, the hanging heart was put down, and he saw that he seemed to be using some props to violently break down the door, so frightened that he immediately closed the space door - the technology of Doraemon World is so advanced, who knows if these space-time police have any props that can break through his space door.

In Doraemon World, after Wang Zhi closed the space door, the space door in Nobita's room immediately disappeared, and a space-time policeman immediately reported to a space-time policeman wearing the same uniform who had just come out of the submarine: "Report to the captain, the space-time passage has disappeared, leaving no traces, and it cannot be traced!" ”

"Seal this place, and then apply for space stripping, and we're going to move the exit from this space passage to a place that's convenient for us to monitor." Said by the captain.

"And what about this kid and this robot tanuki?" A space-time cop asked, but as soon as he finished speaking, he was greeted with Doraemon's roar, "I'm a cat, not a tanuki!" ”

"It's Nobita and Doraemon!" The captain of the space-time police noticed Nobita and Doraemon, he seemed to know them, and said, "I know these two children, and the two of them can always encounter strange things, so don't worry about them, let's take the space where the exit of the space passage is located." ”

・・・・・

In the space-time corridor, Wang Zhi, whose mood had returned to normal, immediately took out the invoice that Doraemon had given before from his four-dimensional pocket.

Now his existence has been discovered by the space-time police of the Doraemon world, although he escaped back, but the space-time police of the Doraemon world will definitely stare at the place where the space door disappeared, then the No. 6 Doraemon world can be declared abandoned, anyway, he doesn't dare to go to that world anymore, and he doesn't even dare to open the space door, who knows if the black technology of the Doraemon world is black enough to break the space door.

can't go to Doraemon World anymore, so this four-dimensional pocket and the things on the invoice are the only gains he got in Doraemon World No. 6, so he immediately browsed the goods on the invoice:

Five bamboo dragonflies and twenty batteries

Twenty boxes of translated konjac

One of the environmental acclimatization lights

Disaster sirens five

An invisibility cloak

Five stone caps

Ten medical kits

Magnifying light one

Shrink the light one

Five shock guns

Any door with a map of all periods of the earth from its formation to the twenty-fourth century.

A piece of time baggage

Pity the love grass

One cloud pot and two boxes of cloud curing agent

A microphone to control the mind

Copy the mind one

A non-living baton

A box of Momotaro rice balls

A tracing staff

There are not many things to buy, but they are very practical, and they are all carefully selected by Wang Zhi, even if they are used in other worlds.

The functions of the bamboo dragonfly, the translation konjac, the arbitrary door, the magnifying lamp, the shrinking lamp, the medical box and the Momotaro rice ball are not much to say, everyone knows that there are only twenty batteries for the bamboo dragonfly, but because the battery can be recycled, it can also be used for a lifetime, if the bamboo dragonfly is not damaged.

Then there is the environmental adaptation lamp, which is the second thing on the list given by Wang Zhi, the person who has been illuminated with this lamp can adapt to any environment, whether it is the seabed or outer space, icebergs or molten slurry, there is no problem, the environment of the other world is naturally not a problem, but the effective time is only twenty-four hours, with this, Wang Zhi dares to go to some other worlds that are not parallel to the earth.

The stealth cloak and stone hat are used to play stealth, and the stealth cloak can be invisible when draped on, but this invisibility can only conceal the vision, it is useless for some people in the high martial arts world, and even some people with keen perception in the ordinary world can find the clues, so Wang Zhi also asked for a stone hat, which is something as inconspicuous as a small pebble on the side of the road after wearing it, others know that you are there, but they will not pay attention to you, it is similar to invisibility, and even the effect is better, and people in the high martial arts world may hide it.

Disaster siren, as the name suggests, will predict danger and will sound an alarm when danger is about to occur, alerting Wang Zhi.

The shock gun, in fact, should be called a stun gun, the person who is hit will be unconscious, the operation is simple, there is no insurance and no need to pull the bolt, just pull the trigger, and more importantly, its appearance is a toy gun, even in the main world, it can be carried on the body at any time, and it may even pass the plane security check, although Wang Zhi, who has a space-time corridor and a four-dimensional pocket, has never worried about the security check.

Poor love grass is a kind of sympathetic prop, as long as you wear it, other people will involuntarily feel pity when they see it, not only when they are in danger, but also when they go to the high martial arts world to apprentice in the future, they will definitely worship one by one, although Wang Zhi is not sure whether this kind of thing that affects people's minds is useful for those masters in the high martial arts world.

The Cloud Maker and Cloud Curing Agent, which are very useful for making things in the Flying Fortress.

The microphone that controls the mind, use this microphone to speak to a person, and that person will do what you say, although that person will react afterwards, but in the ordinary world, it can definitely be regarded as a big killer, because it is completely possible to order others to commit suicide! However, it is estimated that it will be useless when it comes to the world of high martial arts, and the reason is the same as that of poor love grass.

The copy mind is a signal receiver, and as long as you put this signal receiver on the head of any kind of animal, you can transmit the thoughts in your heart to it, so that you can control it, and you can use it to explore any dangerous places.

The non-biological baton can be manipulated by gathering inanimate things, that is to say, Wang Zhi can burn a bunch of terracotta warriors and horses, and then manipulate these terracotta warriors and horses to fight, but considering the hardness of the terracotta warriors and horses made of clay, it is estimated that they can only be used as self-propelled bombs and can be used when blowing up the city gate.

The tracing rod is used to find people, and when it comes to the parallel historical world, there is no need to ask around if you want to collect a few capable ministers, you can directly use the tracing rod to find people, and then tie them back, if you are willing to join the gang, you will stay, and if you are not willing to join the gang, you will kill them, and the talents who can make him look at them must not be left to others.

The last thing to talk about is the time wrapper, which is a very magical thing, printed with clock patterns of different sizes, with front and back, when covering an object with the front, the time flow of the covered object will be accelerated, showing a future state; If it is overlaid on the reverse side, the time of the covered object will be reversed, and it will appear in its past state.

The reason why this magical killer is introduced at the end is because Wang Zhi is not sure if it can be used in other worlds, because time and space are different, although they are two equal concepts, time is often more complex than space. Space is concrete, you can see and touch, so any props such as doors should be able to be used in any world; But time is abstract and elusive, and many worlds may not have the concept of time reversible, and anti-time props such as time and space machines cannot be used, and it is with this in mind that Wang Zhi wrote the big killer of time and space machines on the second page, and some other time-related props are written on the last page.

Because of the appearance of the space-time police, Wang Zhi only got these props from the No. 6 Doraemon World, as well as the disinfection gun and strong gloves he got before, although there were still props such as the Superman cloak that he really wanted to get but he didn't get them, but just these things were already super golden fingers for Wang Zhi, so Wang Zhi still decided to continue to implement the Great Leap Forward plan.
