In the blink of an eye, a month has passed, spring thunder has bursts, and everything has recovered.

In this month, Zhao Ping'an spent the most boring Spring Festival in his life, thanks to the knife wound on his foot, he was 'imprisoned' at home by his parents, and never stepped out of the door.

Of course, Zhao's father and Zhao's mother didn't know that this was a knife wound, otherwise would it be worth it?

Fortunately, after such a long period of recuperation, the wound has almost recovered, at least now it does not feel much pain.

An Ruoxi came once on the eighth day of the Lunar New Year, nominally to greet the New Year, but in fact to say goodbye, she was going back to the UK to continue her studies.

Temporarily, he also gave Zhao Ping'an a note, with only two words on it, but it coincided with Zhao Ping'an's plan - force!

There is no doubt that if he wants to fight against the Wang family and avenge the sword in his legs, it is far from enough for him to be a pure businessman now, so he must develop his own power!

Even if he is a businessman, he must be a red-top businessman like Hu Xueyan and Ma Yun!

And what can bring him this opportunity is the invisibility cloak - his first military product.

Happily, just yesterday, his contribution value finally reached 1 point!

This is due to the fact that the three major projects of the previous year have finally made practical progress.

The three schools in Daliangshan District have now all been completed, and the scale is not small, and each of them is built according to county-level standards. The faculty and staff are all fresh graduates who have gone to the countryside to teach, and the old fritters don't want any of them, because they run the school for free, and even subsidize a Chinese meal, so the source of students is extremely popular.

As for the new village, the first phase of the housing renovation plan has been completed, and Zhao Dazhuang has lived up to expectations and let the villagers spend a happy year in the new house. At present, the second phase of the village committee building, as well as the work of reclaiming the fields to build factories and breeding bases, has also officially started, and it is believed that it will not be long before the new village will become another Huaxi village.

In addition to the football stadium that has already been put into use, the student dormitories built according to the standards of the new hotel and the 'Zhao Ping'an Research Institute' with a special fund have also been put into use, and even the new library, which has not yet been named, has also completed the skeleton pouring of reinforced concrete.

Today, Zhao Ping'an removed the gauze on his feet early in the morning, and then returned to Anping Science and Technology Industrial Park under the repeated advice of his parents.

When he came to the second floor of the research institute, in his own exclusive laboratory, Zhao Ping'an immediately called up the craftsman system and switched it to the mall interface.

At the bottom of the crimson mall interface, a string of [host: Zhao Ping'an, contribution value: 1.02] characters made him happy, for this 1 contribution value, it can really be said that he has gone through a lot of hardship!

So let's see if you're getting the best value for your money!

Locked on the only product on the mall shelf that displayed information, Zhao Ping'an did not hesitate and pressed the [Exchange] button fiercely!

[System prompt: This exchange will cost 1 contribution value, does the host confirm the operation?] 】

When he saw this message, Zhao Ping'an couldn't help but be a little clear, it seemed that every time he made a big operation, the system would always have a prompt message. I have to say that this point is still very humane, lest one day a careless child loses all his little belongings, who can he find to cry?

Click Confirm.

【Ding! Congratulations to the host for obtaining the 'Invisibility Cloak Crafting Book'! 】

"It's finally here!" Although everything is under his control, at this moment, Zhao Ping'an can't help but be excited!

Quickly switched the interface to the warehouse, and found that a yellow line-bound book appeared in the grid of the nine-square grid, and almost without thinking about it, Zhao Ping'an chose [Study] among the options next to him!

Wow –

Like a spring, a stream of information instantly entered the hippocampus in his brain.

The content of this book is not much, far less complicated than the previous natural science skill books, but compared to the manufacturing instructions of a product, it is not small, and various principles, parameters, and formulas, if added together, can also have the appearance of fifty or sixty thousand words, the scale of a simplified novel on the market.

I don't have to say, learn!

Zhao Ping'an closed his eyes and rested on the work chair in the laboratory, as if he was sleeping to outsiders, but in fact, his brain was extremely awake, and he was constantly digesting all the knowledge contained in the 'Invisibility Cloak Manufacturing Book' in a high-speed way.

What made Zhao Ping'an exhale loudly, and at the same time excited, the effect of the invisibility cloak was indeed as he thought, it was not a title party, it was not selling dog meat on the head of a sheep, and it was even more perverted than he imagined!

Visual stealth is just one of its basic functions!

It does this very well by directing light waves and twisting light.

As we all know, people can see objects because they block the passage of light waves. Therefore, if the blocked light wave can bypass the object, then the light will automatically ignore it, and the object will be useless, so as to achieve the purpose of visual invisibility.

In addition to this, what Zhao Ping'an didn't expect was that the invisibility suit could actually avoid radar detection!

Of course, this is just an ordinary radar, not some of the most advanced detection equipment such as thermal biometric detectors and superconducting fluoroscopy detectors.

The main reason why the cloak is able to achieve this outrageous function is that it can absorb specific wavelengths corresponding to its own properties!

Moreover, this wavelength range is not small, which means that ordinary radars in general will be completely ineffective against it!

What this means is self-evident!

To put it simply, when you wear it, you will completely transform into a 'ghost', except for some special environments with top-notch detection equipment, such as some military sites!

It may be a bit sneaky to say this, but that's exactly what the invisibility cloak does!

"It's not in vain that I've put so much thought into it, it's really worth the money!" After learning the function of the invisibility cloak, Zhao Ping'an's heart can be said to be filled with endless joy, there is no doubt that if this thing is really taken out, who doesn't want it?

Even if you don't have big ambitions, take it for a live peeping or something, right?

It's better than a cat watching island blockbusters at home, right?

Belch...... Something seems evil.

Well, let's get down to business.

Of course, as conceived a long time ago, Zhao Ping'an did not have the idea of putting it in the market, not to mention that the formal way will definitely not work, even if it can, if you really let those crazy people get it, the world is not completely chaotic?

Therefore, the plan still did not deviate from the earliest expectations, and if you want to use it for profit, there is only one object, that is, the government army!
