Yao Mountain, this peak at only 909 meters above sea level is the highest mountain in Guilin. Yaoshan mountains are undulating, the vegetation is abundant, almost everywhere there are wild rhododendrons, and the colors are gorgeous, there are many varieties, in the rhododendron season is very attractive to couples to come to spring. Although it is not as famous as the Li River, Yangshuo West Street, and the Butterfly Spring in the ten-mile promenade, it is actually a very good place for people who like to get close to nature.

Xia Yu was holding a four-meter-long package in his hands at the moment, and he was sitting on the cable car to the top of the mountain. Because the length of the package is too long, Xia Yu can only occupy the position of two people by himself, and of course, the money is also paid for two people. Fortunately, the package was not too heavy, so after checking it, the staff of the cable car ropeway agreed to Xia Yu taking the package up on the cable car. The package was tied horizontally to the seat of the cable car, and there was no need to hold it very hard, so Xia Yu was able to enjoy the scenery of Yaoshan very quietly.

Take the cable car all the way up, and there is a dense forest at your feet. Looking around, strange pines and strange stones are dotted everywhere, and famous flowers and plants compete for fragrance. There are flocks of birds flying in the mountains, all kinds of crisp chirping sounds are endless, and there are even more trickling sounds, and the clear and transparent stream flows down the stream, bending in a certain place to form a clear pool.

If you can calm down and feel the purity and comfort of nature, it is undoubtedly a very comfortable way to relax. However, Xia Yu only regarded this as an ordinary scenery to appreciate now, and he did not indulge in it. It's not that he doesn't like to be close to the scenery of nature, but what he has to do later has nothing to do with purity and comfort, and he is about to jump off the top of Yao Mountain.

Of course, this is definitely not because Xia Yu can't think of jumping off the cliff, but because he is equipped with an unpowered delta wing in his package, and if the unpowered delta wing wants to fly, he really has to jump down from a high place, which is a challenge to people's courage and spirit.

The non-powered delta wing is an extreme sport that allows humans to fly freely in the sky, and this triangular bracket composed of aviation aluminum tubes can be used to take off by using terrain such as valleys after reasonable design and matching, and then put on the wing cloth, and finally achieve the purpose of allowing people to fly in the sky.

The delta wing structure is stable, the flight attitude is natural, it belongs to one of the nearest bird flight methods in the human flight tool, and the bionic structure also allows the delta wing to suffer from crosswinds without worrying about their umbrella surface being blown by the wind like the paraglider, only in terms of safety, the delta wing is not only safer than the paraglider, but even safer than the aircraft.

Because the properly designed delta wing can maintain a steady descent rate even when the driver is unconscious, as long as there is no bad luck enough to hit obstacles such as mountain walls and telephone poles, the delta wing can automatically glide gently and descend to the ground, which is a very safe aerial extreme sport.

However, because the delta wing is far less convenient than paragliding in terms of transportation and installation, there are relatively few people who play delta wing in China, but in recent years, many delta wing enthusiasts have slowly appeared, and Xia Yu should be regarded as a group of people who played delta wing relatively early.

The cable car reached the top of the mountain on time, Xia Yu unloaded the package, and then found a relatively flat ground and began to assemble the delta wing. Although there were not many people on the top of the mountain today, there were still some people who ran over to watch Xia Yu fiddling with the delta wings.

People who often come to Yaoshan to play are actually no strangers to the delta wing, because Yaoshan is the first peak in Guilin, and there is a cable car that can go directly to the top of the mountain, which is a very convenient place for many flight enthusiasts to take off, including paragliding, there will always be some flying friends from time to time to come together, after assembling their own flight tools, jump down from the top of Yaoshan Mountain, ride the wind, and enjoy the pleasure and freedom of flying.

It took 20 minutes to assemble the delta wing, buckle himself and the delta wing's flight suit with a lock, put on protective gear and gloves, Xia Yu wiped the sweat from his forehead, and then put on the helmet, lifted the delta wing, and slowly walked to the edge of the cliff.

This huge triangular structure with a wingspan of nearly 11 meters long, in fact, the total weight is less than 45 pounds, and it doesn't even need strength to pick it up against the wind after assembly, and any girl can easily lift it, because the air will lift the delta wing itself when it flows under the surface of the delta wing, which is why the delta wing can fly in the sky.

After checking the delta wing again and making sure that there was nothing wrong, Xia Yu stood on the edge of the cliff.

Looking ahead, there was a cloud of mist, and many mountains in the distance showed only a little emerald green peak, and all their huge mountains were hidden in the clouds. When the white mist drifts slowly with the breeze, these green mountains seem to float in a sea of clouds, looming, like a fairyland.

It looks very beautiful, but it is not too conducive to delta wing flight, in terms of primary delta wing, the maximum speed can reach about 100 kilometers per hour, if it is flying in the mountains, and you can't see the situation ahead, it is easy to have an accident, so Xia Yu can only flatten the wing surface and retreat a little, waiting for the fog to dissipate.

Soon, the clouds and mist that shrouded the Zhengjiayao Mountain area dissipated under the sunlight. Standing on the top of Yao Mountain, Xia Yu took a deep breath, then took a few quick steps forward with his delta wings, and then jumped out from the edge of the cliff.

The whirring wind immediately sounded in the ears, but because of the helmet, the impact was not too big, after flying out for nearly 100 meters, gently tilted the delta wing to the left, and Xia Yu, who was flying in the wind, turned left along the lì, found an updraft and continued to circle, gradually crossed the top of Yaoshan Mountain, and continued to rise, when it rose to 1500 meters, Xia Yu broke away from the updraft and began to slide forward, no longer continuing to climb. Because his flight was not reported to the air traffic authority, if he flew too high, he would have died if he happened to hit the plane.

In fact, because the country has not completely opened the low-altitude airspace to civilian spacecraft, at this stage, almost all civilian individual flight behaviors are illegal. Not to mention flying, strictly speaking, even a tethered balloon is illegal.

However, as long as you are not in the key area, it will not affect the normal flight take-off and landing, in fact, the air traffic control department is too lazy to pay attention to you, so the flight friends generally leave the city and run away from the airport to fly.

Yaoshan is more than 30 kilometers away from Liangjiang Airport, generally speaking, the altitude of the passenger plane has dropped to about 1,500 meters at this distance, and any unauthorized flight behavior is absolutely not allowed in this range. However, the mountains of Yaoshan are long, and the complex terrain is not conducive to the construction of the glide path of passenger aircraft, so there is no route arranged in this area over Yaoshan, but many flying friends specially run over to fly.

PS: Regarding the discussion of the naming of aircraft carriers, I think it is almost decided, thank you very much to the brothers who participated in the discussion, I will revise the content of the chapter tonight according to the results of the investigation.
