Birds can fly, people can't fly, but they can make flying machines, and airplanes are human wings, far more powerful than birds' wings.

Man can't outrun most beasts, but man can design and build a car, much faster than beasts can run.

Ye Xing's understanding of human beings themselves is that as long as there is wisdom, everything is not a problem, and cultivation is the same, as long as you spend time, you will definitely be able to find a way, this is the real terrifying ability of human beings, and it is also the ultimate racial talent that is superior to any other creature.

Ye Xing's idea is to design an auxiliary tool that allows people to use the action of air or wind to make their bodies lighter, and with a little skill, they can achieve the effect of flying.

Ye Xing is a person who does what he says, first of all, he experiments with his arms open, and then unfolds his clothes, plus the combined effect of internal force and true qi, plus the rebound power of plants and plants, and finds that it really becomes lighter under the evening breeze, and he really has the feeling of flying on the grass in the sky.

The core of all the techniques is the application of true qi, I used to know that true qi can prolong life, but I have never thought of other effects, and Ye Xing is now trying to find out its effect.

In fact, he has tried to make the consumption of internal force less and more durable by using the true qi, and he also uses the true qi to detect the outside world, inspect the patient's body, and also use it to treat diseases.

Now it is used for the coordination of the body, so that it can automatically adapt to the posture of the body in various situations, and the internal force is more efficient.

After a night of practice, Ye Xing's light skills became more powerful, making full use of the internal force and true qi, as well as the role of the buoyancy of the expansion of the placket of the shirt.

At dawn, Ye Xing took out the spatial ring, the previously used tree adhesive tape, and then cut out the shape of the design. The crucible is then removed and an extremely strong alloy is smelted to make several hollow joints, as well as extremely tough wires.

A few hours later, a pair of large wing skeletons like the wings of bats on Earth were made.

Ye Xing asked Qin Jingxuan to use fine metal thread to sew the gum cloth and the skeleton of the big wings, and soon a pair of fine big wings were completed. The three of them watched Ye Xing use it in the grass, flying on the grass like a big bird, and they were very amazed.

Sure enough, wisdom and creativity are the core innate instincts of human beings, and they are also the ability of human beings to surpass other life.

Spirit beasts also have spiritual intelligence, and they can also cultivate by instinct, but they don't have the creative thinking of humans.

The spirit beast has survived from generation to generation, but it has not seen any substantial and big creative inventions and improvements, and the current bird's nest is no different from the bird's nest 100,000 years ago.

Human beings are different, human beings are always creating new things, even if it is a conservative and traditional country like the Song Kingdom, there are constantly new things, and there is a splendid civilization.

The four of them did not leave, but stayed in this grass for another five days, constantly training and improving.

After five days of refinement and repair, each of the four people changed into a newly modified combat suit of body armor, which usually did not see any difference, but when the small switch under the armpit was pulled, it became a wingsuit flight suit.

Not only can they fly, but they can also put on the gloves on their sleeves and use ten fingers to control the angle and direction of the wingsuit flight suit.

This is the special combat team in Ye Xing's mind, if firearms and guns are used again, Ye Xing feels that it is really good to dominate the world!

Ye Xing said loudly, "Start the special training now, you must fly!" The three of them were also very happy, in fact, it was so much fun to have such powerful equipment!

Ye Xing looked at the map, pointed out to the two eagles, the direction of the distant mountain, and then with a kick of both feet, the person jumped a few feet high, spread his wings, and flew up diagonally. The three of them also flew up and chased after Ye Xing.

With this wingsuit flying equipment, after becoming proficient, the speed was really much faster, much faster than Ye Xing's full strength, and it was also much easier. After six hours, the four of them had roughly mastered the technique of using it before they stopped.

The four of them set up a camp and stayed for another three days, making adjustments and improvements to several details, as well as repeated training.

Now the four of them can fly like birds in the air at a height of several feet, fast, slow, stop, and stagnate can easily do it.

The light skills of the four people were originally excellent, but with this wingsuit flight equipment, they were already real birdmen, and they were not comparable to ordinary light masters at all.

No one knows how big the desert is, but it is only known that the Mo Nan of the Song Kingdom is only a small corner.

It's early winter now, and the wind is very strong, so with the help of the wind, it can fly faster, but it's a little uncomfortable against the wind.

The four of them entered the desert for more than ten days, and they had not seen a human figure, nor had they seen large birds and beasts, only birds and small animals on the grass.

The boundless grassland has made the two girls no longer half excited, only sad faces, too boring and monotonous! And the feeling of flying can't arouse the interest of the four people, and the four of them are swimming dots on the grassland.

After another eight days of northward travel, it snowed, and the temperature dropped to extreme cold, with biting winds and ice in the water.

Fortunately, Ye Xing had already prepared, and the skins of the grassland rabbits killed along the way were all processed and left, and the two women directly made coats and fur hats out of rabbit skins, and wore them outside.

The handiwork of the two daughters has also become extremely skillful, and it can already be said that the two princesses have now become little peasant women.

The snow was very reflective, and there was no sun, so the four of them didn't know exactly how many days they had walked, at least they had traveled nearly a thousand miles in the north direction.

It may be that the direction has always been extremely remote, so I didn't meet herders.

The two eagles let out a long and short chirp in the sky, and under the contact of Ye Xing's divine sense, he knew that there were horses and people in front of him.

The four of them put away their wingsuits first, and then headed in the direction pointed by the two birds.

Because the grassland is flat and vast, it was a long time before the herd of horses came into view.

The four of them ran in the direction of the horses, and soon, several mastiffs rushed over, and several people behind followed on horseback, shouting at the mastiffs.

Ye Xing stood still and said in a loud voice, "We came from the south and got lost. ”

A middle-aged man in the lead looked at the four of them carefully, nodded, and did not doubt it, it is true that such a thing does not know how many times it will happen every year.

The middle-aged man asked Ye Xing, "What are you doing in the desert?" After all, this is still the Song country, but this person is not a Song person, it should be a small border nation.

Ye Xingdao, "We are from the south of the Song Kingdom, and we actually want to come to the desert to buy horses, but we can't find a guide, and we get lost when we walk." ”

The middle-aged man said, "You can't buy a horse like this." All horses must be traded through the Spirit Beast Gate, and no one dares to sell them directly to you. ”

Ye Xingdao, "I know this, but what we want is a real horse, not the kind of inferior horse sold by the Spirit Beast Gate." ”

The man said, "Yes, it is a bad horse to sell to ordinary people, and only a better one is sold to various forces, and the best horse, the Spirit Beast Gate is not sold." ”

Ye Xing asked, "The desert is so big, it's impossible for the Spirit Beast Gate to know who sells good horses, right?" ”

The man said, "Wrong! You see, my hundreds of horses, all of them are marked, each with a different mark, and it is clear which one sells at a glance. ”

Ye Xing stepped forward to take a closer look, only to know that there was a mark on the outside of the horse's thigh that he didn't know how to add to the skin.

Everyone understood that the Spirit Beast Gate used this kind of proprietary mark to know which one sold the horse.

Ye Xing said, "Oh! How do I find a place to trade horses in the Spirit Beast Gate? ”

The man said, "There is a trading ground more than a hundred miles to the east, and there are dozens of them in Monan!" If it were the entire desert, there would be hundreds of such trading venues. The sale of our horses is done on the trading floor and cannot be sold privately to customers. ”

"Every year, the Spirit Beast Sect sends people to mark the newly produced horses and other livestock with their own special potion."

The man said a little helplessly, "The mark is a special elixir of the Spirit Beast Sect, and it will never be erased. And there is a breath that they only understand, the monks of the Spirit Beast Gate, as soon as they smell it, they know that as long as there is a marked horse, they are all sold horses by the Spirit Beast Gate. ”

Ye Xing remembered that many years ago, when he met the Green Wolf Gang, the horses were marked, so the man in black asked him not to want those horses.

Ye Xing asked, "Then the same is true for other beasts and livestock?" ”

The middle-aged man said, "Yes, they all have the unique logo and aura of the Spirit Beast Gate, which others will never be able to imitate." ”

After asking the direction, Ye Xing decided to go to the trading floor first, one was to buy horses, and the other was to find someone to ask for the map and directions.
