After dinner, some made an appointment to go shopping, some went to wash their feet, and some hooked their shoulders to play.

Several CEOs of the import and export company, general manager Mu Yongqiang, two vice presidents Li Qiming and Xiao Chengbo, and Gong Kaiyuan, minister of the second department, were picked up by a silver-white Buick business after leaving the door of the hotel. Zongxin Group also has a branch in Jiangmen, Yangcheng, and this Buick business car is hung with Jiangmen's license plate. Wang Qi followed Zhang Jianjian to set up the exhibition in the past two days, and he has been in this car many times.

Now that the time has passed nine o'clock in the evening, several CEOs and ministers will definitely not go to Jiangmen to inspect, and what to do with the appointment, that is something that can only be understood and cannot be spoken.

Wang Qi was a little envious of these heads who went to hunt wild food, enjoy the wind and snow, and feel the foreign atmosphere. Jiang Minghua and Liu Yu asked him to wash his feet, but Wang Qi had already washed his feet once last night, and it was the hospitality of the head of the regiment, Zhang Jianjian, and he didn't know whether it was public money or the kickbacks he ate in this exhibition, so the three of them followed him to dip some soup, so he didn't want to go, so he politely refused.

There was nowhere to go Wang Qi back to the hotel room, a standard double room.

He stayed here for the past two days. Also living with him was the head of the regiment, Zhang Jianjian.

When he checked into the hotel two days ago and found that Zhang Jianjian called him instead of the more familiar Jiang Minghua and Liu Yu as his roommates, Wang Qi was a little confused at first, but after seeing a lot of tricks in this exhibition, he slowly understood:

Living with a rookie who doesn't understand anything and can't understand it is definitely safer than an old bird who knows everything and can see everything clearly, rest assured!

When Wang Qi opened the door with the room card, he found that there was no one in the room, it was empty, and Zhang Jianjian didn't know where to go.

In fact, last night, this guy didn't come back, called Wang Qi and said that he was going to meet an old classmate in Yangcheng, and he wouldn't come back if he lived in the old classmate at night, and then "hey, hey, hey" let Wang Qi rest assured and boldly "use the room", don't worry about anything.

Wang Qi wanted to "use it well", but unfortunately no one accompanied him to use it, and in the end, it could only be a waste of Zhang Jianjian's good intentions.

Without Zhang Jianjian, Wang Qi was ready to take advantage of this rare time to improve his "portable air conditioner" without anyone to disturb him.

Although his original "portable air conditioner" has undergone an improvement, it has changed from a simple "human-shaped air mass" to a cylindrical "air hood" with excellent cooling effect.

However, even if the "air cover" of this "portable air conditioner 2.0" is still too large. He is not the only one on the booth tomorrow, Park Longzhou and Wu Yali are there, their booth is small, he is cool, Park Longzhou and Wu Yali around him must feel it, in this case, it is impossible for him to unscrupulously take out his "portable air conditioner" and use it.

He also needs to further improve and evolve the "portable air conditioner 2.0" into "portable air conditioner 3.0".

Wang Qi's ultimate vision for his "portable air conditioner" is a layer of "air skin" that is only one millimeter thick and can be tightly intertwined with his body surface, so that he can keep himself in a constant temperature state anytime and anywhere, either "naked in Antarctica without feeling cold" or "covering himself in Africa without feeling hot".

Even, at that time, he imagined such crazy things as "traveling in space with a physical body" and "bathing on the surface of the sun".

Later, he found that in order to realize the idea of "air skin", he first had to build an air hood of a "three-dimensional mannequin" based on himself, and the air hood of this "three-dimensional mannequin" had to be dynamically changing at any time and completely consistent with the shape of his body.

The current Wang Qi, of course, still can't solve this problem.

However, his current needs are not to "travel in space with a physical body" and "bathe on the surface of the sun", but only to cool himself down in a space of about ten square meters, so that he can cool down without letting the other two people notice.

In the next hour, Wang Qi began to renovate his "portable air conditioner 2.0", that is, a "cylindrical hollow air cover" with an outer diameter of 70 cm, an inner diameter of 60 cm, a height of 1.8 meters, and a wall thickness of 10 cm that he has been using in this summer, as long as no one is around.

He first deformed the barrel-shaped hollow air hood into a half-body shape similar to that of a shooting range. The "shoulder width", "body thickness", and "waist height" of the half-body shape can be measured by himself in reality.

As soon as the three data that he roughly measured with a ruler came out, the "half-body hollow air cover" in the cube immediately changed, and it became a bit similar to his upper body.

Next, Wang Qi is about to adjust the head of the half-body.

In this way, Wang Qi can't make it "have a nose and eyes", so he can only make a round, a little larger than his head, like an astronaut's helmet.

After the body and head were done, the whole project was more than half completed.

In the end, Wang Qi adjusted the thickness of the half-body, reducing it from the original ten centimeters to three centimeters, and the frequency was also reduced by half, from the original (1)/(1), that is, once in one second, to the current (1)/(3), that is, once every three seconds.

At this point, his improvement of "portable air conditioner 2.0" has been completed.

After the improvement was completed, Wang Qi immediately tried it out.

Before the renovation, he had turned off the central air conditioning in the room, and at this time, the room without air conditioning had become extremely stuffy.

As soon as the "half-body hollow air cover" was summoned, Wang Qi, who was already hot and sweating, immediately felt a cool breeze, and his head, chest, and back immediately began to cool down.

"Yes, yes, although compared to the 'portable air conditioner 2.0', both the cooling speed and the temperature control range are much smaller, but it can be used when there are people. Wang Qi, who had tried the new air conditioner for a while, nodded with satisfaction.

Yes, his improvement, compared with the original kind of "portable air conditioner 2.0" that can wrap his whole person up and blow cold air at 360 degrees without dead ends, is actually getting worse and worse, not only is the refrigeration effect much worse, but also can only cool his head and upper body.

However, this "half-body vest and helmet"-like air cover can be used when there are people, which is unachievable by the previous "portable air conditioner 2.0" with a power of nearly two horses and cooling down immediately within a radius of several meters as soon as the machine is turned on.

"This improvement is not a real upgrade, but a variant on the basis of the original to adapt to the new environment, so it can't be named 'portable air conditioner 3.0', so it ...... Let's call it 'Portable Air Conditioner 2.1'. Wang Qi gave his improvement a new name.

In this way, there are three kinds of air conditioners in his "air-conditioned room":

1. Portable air conditioner 1.0 - a "humanoid air mass" with his height as the standard, a temperature of 26 ° C, and a thickness of 10 centimeters.

2. Portable air conditioner 2.0 - a "cylindrical air hood" with a thickness of 10 cm, a temperature of 26 °C, and a frequency of 1 time per second, which can completely envelop him.

3, Portable air conditioner 2.1 - a "vest and helmet-shaped air cover" with a thickness of 3 cm, a temperature of 26 °C, and a frequency of 3 seconds once a time, which can only cover his head and upper body.

Three types of air conditioners can be adapted to a variety of different scenarios, and the power can be adjusted at any time by adjusting the temperature and output frequency to adapt to different seasons and temperature control ranges.
