The design and manufacturing drawings of the invisibility cloak are a bit difficult for Roger now, and the fifth-level mechanism is just the kind of level that can be seen but not seen clearly for the third-level mechanic.

It's a bit difficult to understand all of them at once, but to understand some of the modules and ideas, you can try to challenge them.

And, is this an invisibility cloak?

Even if there is no intelligent roadblock problem of the Dharma Hall, this mechanism itself must be understood.

With ready-made drawings in hand, don't you want to make an invisibility cloak yourself?

Just thinking about it made Roger feel excited. In addition to some livelihood reasons, Roger has a great curiosity about the mechanism itself, and usually likes to study it, which is probably one of the reasons why his mechanism skills far exceed those of his peers.

Roger read the instructions about the invisibility cloak in the mechanic's database, it turned out that in the world of the big guys, the invisibility cloak is also divided into many different models and versions, and the invisibility cloak he is looking at now is called "Cain".

"Cain" is the mechanic's own design, in his own words, although it uses the Karakuri and materials of the fifth-level mechanism, if it is based on the practical level, it is probably a little stronger than the ordinary seventh- or eighth-level invisibility cloak.

Because, this invisibility cloak can not only be invisible, but also can block part of the impact of force, and has the function of defensive armor, which can offset or greatly weaken the full force of the martial artist below the eighth level.

Of course, these are not the most proud of this mechanic, and the most proud ability is named "the emperor's new clothes" by him.

In addition to having the ability to help the wearer become invisible, it can also become transparent, completely transparent, and if you wear it at this time, it will be exactly the same as if you were wearing nothing!

"What a boring feature......"

Roger secretly said in his heart, who is idle and wears transparent clothes to show others? No, if you want to show others, you can't see them.

And most importantly, if you turn on the "Emperor's New Clothes" function when you're not wearing them, can you still find this dress?

The three main functions of the cloak are: stealth, protection, and "the emperor's new clothes". Roger felt that if he made the Cain Clothes, he would definitely not be able to use the "Emperor's New Clothes" function once.

However, the materials used to make the Cloak of Invisibility were a bit difficult for Roger. The fifth-level mechanism doesn't have to talk about how expensive the material is, but he only has 1363.57 yuan in the light brain account, and he can't make up the ordinary materials.

Forget it, let's study the drawings first, figure out the drawings and functions first, and then solve the material matter when the time comes.

We have to study how the invisibility cloak solves problems like "smart roadblocks......

The study of the mechanism is a time job, and in the few days that Roger has been working on the "Invisibility Cloak", the qualifiers for the Smart Mechanism Invitational Tournament have begun to slowly kick off.

"Team leader, how are the machines in our group ready to compete?" Roger receives a message from Zhang at the age of three.

Although it is only a nominal name and does not participate in the preparation and work of the competition, perhaps because many students around him have participated in this competition, Zhang Yunhai is still very interested in the intelligent mechanism competition.

"Machine...... What machine are you talking about? ”

"Oh, yes, the Smart Mechanism Invitational Tournament, don't worry, it'll be done soon." Roger paused for a moment, fortunately Zhang Yunhai connected with him, and in the past two days, he only cared about studying the invisibility cloak, but he almost forgot that he had to prepare another participating machine for the organ invitational tournament.

The Organ Invitational is more lenient on the machine, with a volume of less than 0.6 cubic meters and a weight of less than 30 kilograms, and the rest is up to you.

Not to mention making a small mechanism, even if it is a simple robot, it is not difficult for Roger. Just kidding, is it okay for a Level 3 Mechanic to pass the budget competition with his eyes closed?

It's just that what kind of mechanism to use to participate in the competition is something that needs to be carefully considered.

First of all, the cost of this mechanism must be low enough, secondly, this mechanism must be able to cope with the previous game, and finally, this mechanism must not be easy to break.

In short, it is durable and cheap, after all, the 1363.57 yuan family is there, and you can't participate in a competition to spend hundreds, right?

So Roger's strategy for the qualifiers is also very simple, one word: hide.

That's right, if you want your own mechanism not to be bad, there is only one way to pass the qualifiers with just one machine, and that is not to compete with other teams at all.

This not only avoids our wear and tear, but also eliminates the need to configure attacks and defenses, saving maintenance costs and production costs.

In addition, this machine has to be small enough, after all, the rules only say that the total volume must be less than 0.6 cubic meters, as if it does not say how much it must be larger?

This is not the negligence of the previous organizing committees, because the contestants have always made the machine bigger, and how many have made it smaller?

As for the small benefit, it is, of course, the saving of material costs.

So, what should I do?

Make a drone? The drone is small enough, and the mini version of the drone is maneuverable enough......

No, no, even if it is a mini version of the drone, it will cost two or three hundred, and it will be expensive.

"Well, that's a good idea, it's a drone, and there shouldn't be a more cost-effective solution than this."

Roger suddenly seemed to think of something, and he didn't know where to find a piece of paper, and he messed around with a few folds to fold a paper airplane.

The idea of paper airplanes is simply amazing!

There's no better way to follow through on your qualifier plan than a paper airplane to save money in the first place.

Moreover, what flies in the sky is naturally out of the ground combat zone, okay?

Next, as long as the paper plane is kept in the fighting compartment for more than four and a half minutes, the qualifiers should pass safely.

There are three ways to score in qualifying: attacking other teams, snatching the ball, and mixing time.

Mixing time is the easiest but also the hardest, although every time you stick to it, you can get a certain amount of points. But, if time is so confusing, who is going to attack other teams and grab the ball?

Whether it's the heat flames of more than a thousand degrees, or the scavenger robots that attack indiscriminately, the fixed and random traps in the fighting compartment are constantly increasing in intensity and frequency over time, so to put it this way, although the maximum time of each round of qualifiers is eight minutes, few machines can last until five or six minutes.

That's why everyone is desperately trying to improve their attacks and defenses, scoring as many attacks as possible in the fastest time possible, and snatching the trap ball.

Anyway, everyone will be killed by the traps in the fighting compartment in the end, so it is necessary to score as many points as possible before being killed, which is the consistent correct way to play in the Smart Trap Competition.

Of course, Roger is clearly not the user who has adopted this "right play". No way, who made him poor?
