The crisis came suddenly, and the twelfth-level wing demon was almost within a hundred meters of Zhang Tie from the front when Zhang Tie found it.

With two arrows in the palm, and then swinging the nose, Zhang Tie almost accomplished the two things at the same time with the fastest speed.

The arrow in Zhang Tie's palm was a sound strike, but for the twelfth-level wing demon, it didn't have much effect. It just slowed the wing demon's flight speed a bit, and was evaded by the wing demon.

In just such a short moment, Zhang Tie had already done his best. He stepped on the power pedal of the human-powered aircraft quickly and at the same time let the human-powered aircraft cut into a sinking cold air current on the left, and began to quickly face the ground. Dive down.

Zhang Tie understood that in the sky, he was definitely not the opponent of the twelfth-level wing demon at this moment. Last time he was embarrassed by an eleventh-level wing demon. At this time, he encountered a twelfth-level wing demon, except To escape, Zhang Tie couldn't think of any tactics.

The wing monster screamed and chased up from behind. When Zhang Tie let the human-powered plane start to rush down to the ground, the wing monster had approached within 80 meters, sitting on the side of Zhang Tie's body in the cockpit. , The hand was raised back, and another arrow in the palm was sent out. The Wing Demon swung a strange fork on his hand and knocked the arrow in Zhang Tie's palm. However, after such a delay, Zhang Tie pulled away ten more times. Distance of meters.

At the critical moment, Zhang Tie's brain suddenly calmed down. The terrain of the area where the capital of the Titanic Principality was located on the entire aerial map appeared in his mind...

Zhang Tie knew that if he wanted to escape this time, there were only three things he could use at the moment-mountains, water, and the human-powered plane he was driving.

To the east of the city of Tokyu, there is a series of endless hills. On the hills, there will be many wavy updrafts due to the terrain. In those wavy updrafts, you can use a unique glider. The flying skills to obtain far exceed the flying speed in the sky under normal conditions.

And after that hill, further east, more than three hundred kilometers away from the hill, there is a huge lake. The lake is very large, with a length and width of more than two hundred kilometers each, which seems to be called a star. Yehu Lake is the largest freshwater lake in the Titanic Principality. As long as you get there, even if you lose another human-powered aircraft, your chances of fleeing here will increase.

In the sky, Zhang Tie was not an opponent of the twelfth-level Wing Demon, but in the water, Zhang Tie had really never encountered an opponent.

Between this chase and flee, in the blink of an eye, Zhang Tie quickly dived from an altitude of more than 10,000 meters to an altitude of three to four kilometers. Under the friction of the violent air current, the fast-rotating propellers in front of the human-powered aircraft gave off strange expressions. The strange whistling sound is almost deafening.

Zhang Tie released a few more arrows in his palm, hindering the speed of the Wing Demon chasing him a little, but it was only a little bit. In the process, the Wing Demon still distanced it from Zhang Tie’s human plane. Pulled in to within 60 meters.

If it were replaced by the glider that Zhang Tie piloted before, Zhang Tie might have been caught up by the Wing Demon at this time. The extra power provided by the propeller of the human-powered aircraft slowed the speed that Zhang Tie had at this moment. Time for the Wing Demon to catch up.

The cold wind in the air blew his face, the strange screams of the propellers rang in his ears, and the things on the ground under his feet became more and more clear. At first glance, Zhang Tie could see the dense military camps and demonized puppets on the ground, the pyramid. The same Roshan seemed even more terrifying at this time, but at this moment Zhang Tie had no time to take a closer look, but fleeing wholeheartedly.

Just when Zhang Tie was about to see the hill in the distance, the thing that worries Zhang Tie the most happened. In front of and to the left of Zhang Tie, two purple black dots approached quickly in the air. .

Three twelve-level wing demons? What grand prize did you win today?

I rely on!

Zhang Tie had no time to think about it, but as soon as he stretched out his hand, he took off one of the standard flying spears that were hung on the outer weapon pylons on both sides of the glider's cockpit to deal with the tenth-level wing devil, and turned to face behind him. The Wing Demon threw it out.

The power of the standard flying spear is not comparable to that of an arrow in the palm. The flying spear was thrown, almost in the blink of an eye, over 50 meters of space, and came to the front of the twelfth-level wing demon, the twelfth-level wing demon. With the fork in his hand, the flying spear thrown by Zhang Tie was smashed into the air with a loud noise, but the huge force on the flying spear caused the twelfth-level Wing Demon's body to shake back. He flew upside down for more than ten meters before flapping his wings to stop his body, and then quickly caught up.

After doing this, Zhang Tie's distance from the nearest twelfth-level wing demon suddenly stretched to a hundred meters away. The twelfth-level wing demon screamed in the air, seeming to be very angry. It also seemed to remind the other two flying wing demons to pay attention to Zhang Tie's methods.

When the flying spears on the weapon racks on both sides of the cockpit of the human-powered aircraft were almost thrown out by Zhang Tie, Zhang Tie finally drove the glider into the sky above the hill, and the three twelfth-level wing demons also The encirclement of Zhang Tie was completed in the sky above the hill. When the three twelfth-level wing demons completed the encirclement of Zhang Tie, the distance between each wing demons and Zhang Tie was already within a hundred meters.

For anyone, within this distance, whether he is flying a human-powered aircraft or a glider, it is absolutely impossible to escape the encirclement of the three twelfth-level wing demons.

Without the undulating hills on the ground, Zhang Tie also felt that he could not escape. Even the people who have been watching this wonderful aerial chase silently on the ground in the distance, at this time, feel that everything can be settled.

However, at this moment, Zhang Tie's human plane finally entered the sky above the hill.

The undulating hills will form wave-like air currents in the air. With keen perception, Zhang Tie drives the glider and starts to shuttle like butterflies through the undulating terrain dynamic updraft. In such a shuttle, Zhang Tie The speed of the human-powered plane that was piloted suddenly increased, and the twelfth-level Wing Demon behind him was thrown away.

This is Zhang Tie's unique flying skill developed by taking advantage of the characteristics of gliders. Zhang Tie named it-Shear Layer Glides with Force.

The shear layer can only be used to glide over terrain with hills. The terrain dynamic updraft in these places is very special, the sense of hierarchy is very obvious, and the speed of the airflow is also very different. Flying in such a place, as long as The glider is continuously maneuvering in a curve in the airflow. Every time the glider turns, the speed of Zhang Tie will increase.

In nature, the flying method of birds closest to this gliding technique is the flight of seagulls between waves. At this time, the undulating hills on the ground are equivalent to the undulating waves, undulating waves and terrain on the sea. Bringing undulating air currents, the speed of the undulating air currents will have a drop, which is the basis for the flight of the shear layer to glide.

In such a flight, the airspeed lost in each turn will be less than the gain brought by the difference in air velocity, so that speed and energy can be accumulated continuously. The process of acceleration occurs when the airflow is static or low-speed area turning into a high-speed airflow at a large angle. In this process, the speed of the glider relative to the air is reduced, but the speed relative to the ground is increased. The speed loses part after turning at a large angle again, and then enters into the high-speed airflow again to accelerate. In this way, the airspeed is reduced-the ground speed is increased-the ground speed is changed to airspeed, so that the speed of the glider reaches the extreme...

Zhang Tie has never shown such flying skills in front of others, because for other glider pilots, they want to fly at high speeds and are keenly aware of them at low altitudes close to the ground for several hundred meters. It is simply impossible to get to the speed changes and levels of those airflows, not to mention the frequent and terrible overloads caused by the glider turning at a large angle. Such overloads, not to mention people, if the strength of the glider is slightly weaker. , It is possible to disintegrate instantly when turning.

This kind of flying skill is completely an unattainable "skill" for glider pilots.

The last time Zhang Tie was dropped into the water by the eleventh-level wing demon and lost a glider. The biggest reason was that when Zhang Tie encountered the wing demon, there was no terrain at all within a few hundred miles. It can be used, letting his shear layer take advantage of the ability to glide, completely useless.

But this time the situation was different. Outside Tokei City, there happened to be a vast hill for him to use, so that his abilities that he hadn't shown could be used, and it was an infinite road.

The propeller driven by the power pedal on his foot just allows Zhang Tie to make up for his loss of speed when he turns out of the high-speed airflow, so that he can cut into the high-speed airflow again at a faster speed, and obtain a faster speed. After several changes, the speed of the human-powered plane driven by Zhang Tie had exceeded 600 kilometers per hour, and the three winged monsters who were chasing him were thrown away.

While the wing magic that uses the flapping-wing principle to fly may sometimes use the airflow in the air to do some gliding movements, but their body looks like where they are, what aerodynamic layout, what lift and drag are more than these indicators. In terms of the ability to use air currents, they are definitely not as good as some birds. Compared with human gliders, there are some gaps, so even in the same environment, they can't catch up with Zhang Tie.

The three winged demons that were thrown away by Zhang Tie let out an angry and unpleasant snarling behind him. Just when Zhang Tie thought he had thrown away a few winged demons, a powerful breath suddenly rose from the ground.

Zhang Tie, who had just felt this breath, instinctively felt that it was a little bad, had not had time to make any response. The right wing of the human-powered plane he was flying was suddenly shattered by a force.

After the right wing of the human-powered aircraft was shattered, Zhang Tie heard a terrifying popping sound from his ears, tearing the sound barrier.

Powerful sound strike!

As soon as this thought appeared, Zhang Tie and the human-powered aircraft he was driving had already rotated, lost control, and smashed into the ground...
