It was not Xiao Ning who suffered from altitude sickness.

It's Liu Weiwei.

If you slowly move from a low altitude to a high altitude and take "Rhodiola" for a period of time in advance, the problem of altitude sickness will be significantly improved.

But Xiao Ning and his entourage were airborne directly from the low-altitude Rongcheng to Kangding Airport.

The average elevation of Rongcheng is only 500 meters.

But Kangding Airport, which reaches an altitude of more than 4,200 meters, is indeed a proper high-altitude airport.

A plateau airport is usually defined as an airport built at an altitude of 1,524 meters (5,000 feet) and above, but below 2,438 meters (8,000 feet).

The High Plateau Airport, on the other hand, is an airport with an altitude of more than 2,438 meters.

Looking at the entire water blue star, only the dragon country has the most high-altitude airports, and it directly occupies the ranking of the world's top high-altitude airports.

The highest airport in the world is Daocheng Yading Airport, which is located at an altitude of 4,411 meters in Sichuan Province.

The second highest airport is the Qamdo Bangda Airport, located at an altitude of 4,334 meters above sea level in Zone Z.

The third highest airport in altitude is Ali Kunsha Airport, which is located at an altitude of 4,274 meters in Zone Z.

As for the fourth-highest airport, it is the Kangding Airport where Xiao Ning and others are located, and the altitude of the accurate airport is 4,238 meters.

The sudden increase in altitude in a short period of time is especially susceptible to altitude sickness.

Liu Weiwei obviously felt dizzy when she just got off the plane, and waited until the group met with the staff of the Austrian Red Bull Zheduoshan Special Team.

Because of the feeling of dizziness and headache, she was even unable to walk for a while, so she could only rest on a chair at the airport for the time being.

When ordinary people go to plateau areas, many people will have "altitude sickness" because the body is not adapted to the air density of the plateau and the body's poor tolerance to hypoxia.

The so-called "altitude sickness" is actually a series of symptoms such as dizziness, headache, fatigue, and insomnia after the body is in a low-pressure and low-oxygen environment.

In severe cases, altitude sickness can be a direct cause of death.

Regarding the issue of altitude sickness, Xiao Ning had already thought about it before leaving.

He is now in a staggering 18.0 fitness.

What is this concept?

In the mouth of the system, Xiao Ning's previous physical fitness data was still 17.5, and aside from his skills, his physical indicators were enough to sprint to the existing human world records in various sports.

Xiao Ning, who once again gained 0.5 points of physical fitness after the low-altitude skydiving mission of the Twin Towers, has reached 18 points of physical fitness now, and has been comparable to the strongest athletes on the Water Blue Star in many sports fields, or even surpassed them.

With this kind of physical condition, Xiao Ning didn't feel that he would have any altitude sickness.

Theoretically, it is not necessary that good health will not cause altitude sickness.

Whether there is altitude sickness and whether altitude sickness is severe also depends on which aspect of the body is better.

Many athletes with strong physical fitness and heavy endurance do not suffer from altitude sickness, such as long-distance runners, football players, basketball players, swimmers, etc.

Because they are in long-term aerobic exercise, the body's ability to tolerate hypoxia will be stronger than that of ordinary people, and the ability to adapt to the environment will be stronger.

Athletes in anaerobic short-term sports such as weightlifting actually have a poor tolerance to hypoxia.

Even if the overall quality is still stronger than that of ordinary people, it is normal for them to have altitude sickness.

As for Xiao Ning......

He is N-thalmatic.

Aerobic exercise is like a marathon, he is invincible.

Anaerobic exercises such as sprinting, long jump, he is still invincible.

So after thinking about it briefly before leaving, Xiao Ning was sure that he couldn't possibly have altitude sickness at all.

And now he is indeed like no one.

At this time, the people of the Red Bull Zheduoshan project team have already brought a vial of oxygen.

With the help of a female staff member, Liu Weiwei took a few breaths of oxygen before her symptoms eased slightly.

However, for the sake of prudence, Xiao Ning planned not to take Liu Weiwei with him for the next trip to Zheduoshan.

The average altitude of Zheduo Mountain is very high, and the highest point is even higher than Kangding Airport, the fourth highest airport in the world.

As soon as Liu Weiwei got off the plane, the altitude sickness was quite serious, and it was really dangerous to go to Zheduo Mountain.

After telling Liu Weiwei about this, although Liu Weiwei wanted to accompany Xiao Ning very much, she was really unwell, so she could only agree.

Because it was already night, even if I rushed to Zheduo Mountain, I couldn't see anything, so in the end, under the arrangement of the Red Bull staff, Xiao Ning and his party temporarily stayed and rested in the lower altitude of Kangding City (2560 meters) tonight.

Early the next morning.

In addition to Xiao Ning, including Liu Weiwei, who still felt unwell, several assistants who accompanied Xiao Ning from the magic capital this time also felt headaches, dizziness and other symptoms.

Several assistants were specially recruited by Liu Weiwei in order to facilitate Xiao Ning's usual work and life.

Originally, Liu Weiwei wanted to bring these people over, and she could always help Xiao Ning at some times.

But now it seems that everyone, like her, really can't help anything.

However, Xiao Ning didn't feel anything, and after comforting everyone, he asked the staff of Red Bull to help take care of Liu Weiwei and others, and he followed the Red Bull staff of the Zheduoshan project team to Zheduoshan directly.

In order to allow Xiao Ning to have a clearer understanding of the situation of the mountainous route.

It is not a car to go from Kangding to Zheduoshan.

Instead, he returned to Kangding Airport, where he landed yesterday, and boarded a plateau helicopter rented by Red Bull.

It's a sunny day.

The helicopter took off, and Xiao Ning's mind was filled with all the scenery as far as his eyes could see.

It's completely different from those big cities in the steel forest.

Overlooking the ground above Kangding, there are only empty fields, and most of the urban buildings with extremely strong ethnic characteristics are very low......

And in the sky of the city, there is an endless blue sky, which covers the city like a whole blue cloth.

Not to mention feeling the rhythm of the city specifically, Xiao Ning can feel the taste of leisure and freedom just by sitting on the helicopter and enjoying all the beautiful scenery around him.

In the roar of the helicopter, the scenery below kept receding, and it didn't take much time for Xiao Ning and the others to reach the sky above Zheduo Mountain.

This is the first time that Xiao Ning has overlooked the entire mountain in the sky above Zheduo Mountain.

Twists and turns, steep slopes, and all sorts of large trucks dot the winding road.

After circling the helicopter around the mountain for two more laps, the plane stopped at a nearby tarmac near Mt. Zheduo.

Then Xiao Ning finally met the person in charge of the Austrian Red Bull Zheduo Mountain project team.

"Mr. Xiao, my name is Chen Qing, and I am the person in charge of the project in which Red Bull cooperated with you to complete the downhill challenge."

"Because yesterday we were here to evaluate the road conditions and make some preparations, I couldn't pick you up at the airport in person, so please don't be surprised about this."

Chen Qing, who was waiting on this tarmac in advance, greeted Xiao Ning just when he stepped off the helicopter, because he knew that Zou Yitian valued Xiao Ning, and he even made a special explanation for the fact that he did not pick up the plane yesterday.

Xiao Ning waved his hand to show that it didn't matter, and then asked, "Mr. Chen, you have already seen the road conditions on the spot yesterday, right?" ”

Chen Qing nodded: "Because in recent years, the main road part of G318 has been renovated and maintained, and this section of the road in Zheduoshan can be said to be the first crossing to really enter western Sichuan, after all, the first pass of Khamba......"

"So in fact, the whole section of the road has been renovated and maintained by the government in recent years, and the road condition is very good."

"There are no bad roads like those in the early years, with three potholes in one step."

"But ......"

Chen Qing paused, and then continued: "After all, the geographical environment is special, and there are many trucks coming and going, so there is still a lot of gravel on the road......

"Our plan is to clean the road to a certain extent in advance of your challenge to ensure that the road conditions are as safe as possible."

Xiao Ning nodded, and then said, "Let me drive up there first." ”

Soon.

The Red Bull team got Xiao Ning a car.

This is still Xiao Ning's special request.

He did not choose an off-road vehicle with better passability, but specifically asked the Red Bull team to find a sedan with a relatively low chassis.

The reason why Xiao Ning did this was to perceive the road surface and road conditions more clearly when driving.

After all, the chassis of the off-road vehicle is relatively high, and the ability to filter vibration is better, if you are driving an off-road vehicle, you may ignore a lot of details because of the car.

Chen Qing personally accompanied Xiao Ning all the way up from the bottom of the mountain.

Before, Chen Qing was worried that Xiao Ning would suddenly come and be interested in driving wildly on this mountainous mountain.

After all, as a staff member of the Red Bull Extreme Sports Department, Chen Qing knows very well that Xiao Ning's driving skills are very rebellious.

So he was actually ready to be foaming at the mouth by Xiao Ning's various fierce driving.

But in fact, Xiao Ning drove very gently all the way up or down the mountain.

It even deliberately keeps the engine speed in a very stable range.

There was no sharp acceleration or sharp deceleration.

This is the most comfortable way to drive in the car.

Along the way, Chen Qing would take the initiative to explain the situation to Xiao Ning whenever he passed some locations that had been marked by the team before.

Similar to which there was a landslide some time ago and the road was repaired, and there was a driver in a certain place who was tired of driving, and the road protection stone pier was damaged and even people and cars were rolled down the mountain.

Xiao Ning listened while driving the car to perceive the specific situation of the road.

After driving a whole circle, after getting off the car and taking a look at some sections, Xiao Ning followed and drove Chen Qing down the mountain again.

I have to say that in fact, the situation of folding many mountains, at least the road surface conditions and the comprehensive road conditions, are much better than Xiao Ning thought before.

A few years ago, when he came to travel, there were still a lot of potholes on the road......

Just like Chen Qing told him at the beginning, the road of G318, which has now been fully commercialized, has really changed completely.

The road is really visible to the naked eye, much better.

In some sections of the road up and down the mountain, Xiao Ning even felt that the smoothness of the road was much better than that of the Autumn Mountain.

Of course.

Although the road conditions are good, this does make Xiao Ning relax a little.

But there are still other downsides.

For example, it's almost the depths of winter after all.

Originally, the plateau area of western Sichuan was colder than other places, so the outdoor temperature at this time has been hovering between 0 degrees and 3 or 4 degrees.

If the temperature drops at night, there is a high chance that the road surface will be darkly icy.

The so-called "dark ice" actually refers to the fact that less water condenses into ice on the road surface.

However, if you don't stop to take a closer look, you probably won't notice it when you drive.

Another example is the weather problem mentioned by Chen Qing.

According to the forecast of the meteorological observatory in the past few days, the climate conditions near Zheduoshan are very good, but if it is delayed for a few more days, it is really not necessarily.

What's more, the forecast of the meteorological station is not 100% accurate.

Although now it looks like there has been no snow in the last few days.

But who can say for sure?

What if?

In case it really snows here, with the high altitude situation, even if it is not to the extent that the road management department orders the closure of the mountain, then normal cars driving on this winding mountain road will have to install snow chains.

And once this happens, it is absolutely impossible for the longboard to slide on the road.

Again.

Once there is really extreme weather, for the sake of safety, the road management department will really close the mountain road for a day or two.

Then even if the mountain closure is lifted later, the mountain road will be folded for a while and a half, and it will not have the conditions for a long downhill.

The reason is simple.

The weather is so extreme that the mountain is closed, and it must only be a very violent blizzard.

Even if the mountains are closed, the snow melts, and the roads are cleared, it is not something that can be done in a day or two.

Unless Xiao Ning can transform a longboard into a snowboard, he really won't be able to rappel in the mountains in a short period of time.

Finally, he followed Chen Qing back to the small rest point that Red Bull had temporarily set up near Zheduo Mountain.

Including the person in charge Chen Qing, many staff members of the Austrian Red Bull Zheduoshan project team summarized the information on the situation of Zheduoshan.

Xiao Ning, in a rather indifferent state, directly gave an order to everyone present that surprised everyone.

"Team Leader Chen told me before, that you have already obtained the permission of the local authorities."

"Given the weather and road conditions, there is a high probability that there will be changes that we cannot anticipate due to the season."

"So I think we should start cleaning up the roads now."

"This afternoon!"

"Let's get started!"

After Xiao Ning finished these words, the audience was silent.

Originally, according to the team's expectations, they had to cooperate with Xiao Ning to fully prepare for the specific sections of each section of the downhill downhill.

But now Xiao Ning just went to see a lap of the road, and he was about to start the challenge?

Although he did go to take a look, whether it was a helicopter or a car up the mountain, it would add up to that time!

I didn't know the road in detail!

So it's like there's no preparation at all!

On the Zheduo Mountain, which is more than 4,000 meters above sea level, there is almost no preparation for the longboard downhill challenge?

This Nima is also dead, right?
