The crisis came suddenly, and almost when Zhang Tie found it, the twelfth-level winged demon had already forced within a hundred meters of Zhang Tie from the front.
Sending out two arrows in his palm, and then swinging the nose of the plane, Zhang Tie almost did these two things at the same time with the fastest speed.
Zhang Tie's arrow in his palm was a sound strike, but for the twelfth-level Wing Demon, it didn't have much effect, it just slowed down the Wing Demon's flight speed a little, and it was avoided by the Wing Demon.
In such a short moment, Zhang Tie had already used all his strength, stepping on the power pedal of the human-powered plane with his feet at a rapid pace, and at the same time letting the human-powered plane cut into a sinking cold air flow on the left, and began to dive down quickly towards the ground.
Zhang Tie understood that in the sky, he was definitely not the opponent of the twelfth-level winged demon at the moment, last time he was embarrassed by an eleven-level winged demon, at this time, when he encountered a twelfth-level winged demon, except for escaping, Zhang Tie really couldn't think of any tricks.
The winged demon screamed, chased after him from behind, when Zhang Tie made the artificial plane start to rush down to the ground, the winged demon had approached within 80 meters, sitting on the side of Zhang Tie's body in the cockpit, his hand raised back, and another palm arrow was issued, the winged demon waved a strange fork in his hand, knocking Zhang Tie's palm arrow away, but it was delayed, and Zhang Tie pulled away a distance of ten meters.
At the critical moment, Zhang Tie's brain calmed down suddenly, and the terrain of the area where Tokyi City, the capital of the Principality of Titanic, was marked on the entire aerial map, suddenly appeared in his mind Zhang Tie knew that this time, if he wanted to escape, all he could use at the moment was three mountains and rivers, water, and the human-powered plane he piloted.
To the east of Tokj, there is a rolling hill on which many wave-like updrafts are formed due to the topography, and in these wave-shaped updrafts you can use a unique glider's flying technique to achieve speeds far beyond normal conditions in the sky.
And beyond that hill, further east, more than 300 kilometers away from that hill, there is a huge lake, the range of that lake is very large, more than 200 kilometers in length and width, it seems to be called Star Leaf Lake, it is the largest freshwater lake in the Principality of Titanic, as long as you get there, even if you lose a manpower plane, your chances of escaping here will be greatly increased.
In the sky, Zhang Tie was not the opponent of the twelfth-level Winged Demon, but in the water, Zhang Tie really had never encountered an opponent.
Between this chase and escape, in the blink of an eye, Zhang Tie quickly dived from an altitude of more than 10,000 meters to an altitude of three or four thousand meters, and under the friction of the violent air current, the propeller that was rapidly rotating in front of the human-powered aircraft made a strange and strange whistling sound, which was simply deafening.
Zhang Tie released a few more arrows in his palm, hindering the speed of the Winged Demon chasing him a little, but it was only a little, and in the process, the Winged Demon still pulled the distance between it and Zhang Tie's human-powered plane within 60 meters again.
If it was the glider that Zhang Tie piloted before, at this time, Zhang Tie might have been caught up by the Wing Demon, and the extra power provided by the propeller of the human-powered aircraft made Zhang Tie have that little extra speed at the moment, delaying the time for the Wing Demon to catch up.
The cold wind in the air was blowing, the strange screams of the propellers sounded in his ears, and the things on the ground under his feet became clearer and clearer, at first glance, Zhang Tie could see the dense military camps and demonized puppets on the ground, and the pyramid-like Roshan was even more terrifying at this time, but at this moment Zhang Tie had no time to look carefully, but fled with all his heart.
Just when Zhang Tie was almost about to see the hill in the distance, the thing that worried Zhang Tie the most happened, in front of Zhang Tie and to the left, two more purple black dots quickly approached in the air.
The three twelve-level Winged Demons have won some kind of jackpot today No way Zhang Tie didn't have 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 peripheral weapon pylons on both sides of the glider's cockpit to deal with the tenth-level Winged Demon, turned around and threw it at the Winged Demon behind him.
The power of the standard flying spear is not comparable to the arrow in the palm, the flying spear was thrown, almost in the blink of an eye, it crossed the space of more than fifty meters, and came to the front of the twelfth-level winged demon, the twelfth-level winged demon smashed it with the fork in his hand, and in a loud bang, the flying spear thrown by Zhang Tie was smashed away, but the huge power on the flying spear shook the body of the twelfth-level winged demon, and it flew more than ten meters upside down before flapping his wings and stopping his body, and then hurriedly catching up.
In this way, the distance between Zhang Tie and the nearest twelfth-level winged demon suddenly widened to a hundred meters away, and the twelfth-level winged demon screamed in the air, which seemed to be very angry, and seemed to remind the other two winged demons who flew over to pay attention to Zhang Tie's methods.
When the flying spears on the weapon pylons on both sides of the cockpit of the human-powered aircraft were almost completely thrown by Zhang Tie, Zhang Tie finally drove the glider into the sky above the hill, and the three twelfth-level winged demons also completed the encirclement of Zhang Tie in the sky above the hill, and when the three twelfth-level winged demons completed the encirclement of Zhang Tie, the distance between each winged demon and Zhang Tie was already within 100 meters.
For anyone, at this distance, no matter whether they were piloting a human-powered plane or a glider, it would be absolutely impossible for anyone to escape from the encirclement of the three twelve-level winged demons.
If it weren't for the undulating hills on the ground, Zhang Tie felt that he would not have been able to escape.
Even the people who had been silently watching this wonderful air chase on the ground in the distance felt that everything could be settled at this time.
However, at this time, the manpower plane piloted by Zhang Tie finally entered the sky above the hill.
The undulating hills will form a wave-like air flow in the air, with a keen perception, Zhang Tie piloted the glider and began to shuttle like a butterfly in the updraft of those undulating terrain power, in this shuttle, the speed of the human-powered aircraft piloted by Zhang Tie suddenly accelerated, and suddenly threw off a twelve-level wing demon behind him.
This is Zhang Tie's unique flying technique developed by using the characteristics of a glider, and Zhang Tie named it shear layer to glide with force.
The shear layer can only be carried out in the sky above the terrain with hills, the topographic 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.
In nature, the closest to this gliding technique is the flight of seagulls between the waves, the undulating hills on the ground at this time are equivalent to the undulating waves on the sea, the undulating waves and the terrain bring undulating air currents, and the speed of the undulating air currents will be different, which is the flight basis of the shear layer with the help of gliding.
In such a flight, the loss of airspeed in each turn is less than the gain from the difference in airflow speed, so that speed and energy can be accumulated continuously.
The process of acceleration occurs in the process of turning from a large angle into a high-speed airflow from a stationary or low-speed area, in this process, the speed of the glider relative to the air becomes smaller, but the speed relative to the ground becomes larger, and the speed obtained loses a part after another large-angle turn, and then enters the high-speed airflow again to gain acceleration, so that the speed of the glider reaches the extreme in the continuous cycle of decreasing the ground speed and increasing the ground speed into airspeed Zhang Tie has never shown such flying skills in front of others, because for other glider pilots, if they want to fly at high speed, and they are keenly aware of the changes and levels of the speed of those air currents in a low altitude of several hundred meters close to the ground, it is simply impossible, not to mention that they have to frequently bear the terrible overload brought by the glider's large-angle turn, such an overload, not to mention a person, if the strength of the glider is slightly worse, it is possible to disintegrate instantly when turning.
This kind of flying skill is completely a "miracle skill" that glider pilots can not reach.
The last time Zhang Tie was thrown into the water by the eleventh-level Winged Demon and lost a glider, the biggest reason was that when Zhang Tie encountered that Winged Demon, there was no terrain to use within a few hundred miles around, so his shear layer was completely useless with the help of gliding skills.
And this time the situation is different, outside Tokoi City, there is just a vast hill that he can use, so that his ability that has not been revealed can be brought into play, which can be regarded as an endless road.
The propeller driven by the power pedal on his feet just allowed Zhang Tie to make up for the loss of speed when he turned out of the high-speed airflow, so that he could cut into the high-speed airflow again at a faster speed and gain faster speed, after several changes, the speed of the human-powered plane piloted by Zhang Tie had exceeded 600 kilometers per hour, and the three winged demons chasing him were thrown away at once.
Although the winged demons who use the principle of flapping wings to fly can sometimes use the airflow in the air to do some gliding actions, but where is the appearance of their bodies, what aerodynamic layout, what lift-to-drag ratio these indicators are not to talk about, to talk about the ability to use the airflow, they are definitely not inferior to some birds, and compared with human gliders, there are also 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 ugly roar behind him, and just when Zhang Tie thought that he had thrown a few winged demons away, a powerful aura suddenly rose from the ground.
Zhang Tie, who had just felt this breath and instinctively felt that something was wrong, didn't have time to react, and the right wing of the human-powered plane he was piloting was suddenly shattered by a force.
After the right wing of the human-powered plane was shattered, Zhang Tie heard a terrifying popping sound tearing through the sound barrier in his ears.
Powerful sonic strikes As soon as this thought appeared, Zhang Tie and the human-powered plane he piloted were already spinning, losing control, and smashing down to the ground:
