Chapter 21 The Eagle Broken Wings

The crisis came suddenly, and almost when Zhang Tie found it, the twelfth-level winged demon was already within 100 meters of Zhang Tie from the front.

After firing two arrows in the palm, and then swinging the nose of the aircraft, Zhang Tie almost finished these two things at the same time at the fastest speed.

The arrow in Zhang Tie's palm was a sonic strike, but it didn't have much effect on the twelfth-level Winged Demon. It just slowed down the flying speed of the Winged Demon for a while, and the Winged Demon avoided it.

In such a short moment, Zhang Tie had already tried his best to step on the power pedal of the human-powered plane quickly, and at the same time let the human-powered plane cut into a sinking cold air current on the left, and began to quickly move towards the ground. swoop down.

Zhang Tie understands that in the sky, he is definitely not the opponent of the twelfth-level winged demon at this moment. Last time he was embarrassed by an eleventh-level winged demon. To escape, Zhang Tie really couldn't think of any tricks.

The Winged Demon screamed and chased after him. When Zhang Tie made the human-powered plane start to rush down to the ground, the Winged Demon had already approached within 80 meters, sitting on the side of Zhang Tie's body in the cockpit. , raised his hand back, and another arrow in his palm was shot out. The Winged Demon waved a strange fork in his hand and knocked the arrow in Zhang Tie's palm into the air, but after such a delay, Zhang Tie pulled the arrow away ten times meter distance.

At the critical moment, Zhang Tie's brain suddenly calmed down, and the terrain of the area where the capital of the Titanic Principality, Tokey City, was marked on the entire aerial map suddenly 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—mountain, water, and the human-powered plane he was driving.

There is an endless hill to the east of Tokey City, on which there will be a lot of wavy updrafts due to the terrain. In those wavy updrafts, I can use a unique glider flying skills, gaining speeds far exceeding normal conditions in the sky.

After passing the hill, in the east, more than 300 kilometers away from the hill, there is a huge lake. The lake is very large, with a length and width of more than 200 kilometers. Yehu Lake is the largest freshwater lake in the Principality of Titanic. As long as you get there, even if you lose another human-powered plane, your chances of escaping here will increase greatly.

In the sky, Zhang Tie is not an opponent of the twelfth-level Winged Demon, but in the water, Zhang Tie has never met an opponent.

During this pursuit and escape, in the blink of an eye, Zhang Tie quickly dived from an altitude of more than 10,000 meters to a height of three to four kilometers. The strange whistling sound was almost deafening.

Zhang Tie released a few more arrows in his palm, hindering the speed of the Winged Demon from chasing him a little more, but only a little. Pulled in to within 60 meters.

If it were the glider that Zhang Tie drove before, Zhang Tie might have been overtaken by the Winged Demon at this time. The extra power provided by the propeller of the human-powered plane made Zhang Tie's extra speed at this moment slow down. It took time for the Winged Demon to catch up.

The cold wind was blowing in the air, and the strange screams from the propellers rang in his ears. The things on the ground under his feet became more and more clear. At first glance, Zhang Tie could see the densely packed military camps and demonized puppets on the ground. The same Roshan looked even more terrifying at this time, but at this moment Zhang Tie had no time to look at it carefully, but was focused on running away.

Just when Zhang Tie was about to see the hills in the distance,

What worried Zhang Tie the most happened. In front of and to the left of Zhang Tie, two more purple black spots approached quickly in the air.

Three level 12 Winged Demons? What 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 a standard flying spear that was hung on the peripheral weapon racks on both sides of the cockpit of the glider, which was used to deal with the tenth-level winged demons, and turned around to face behind him. The Winged Demon threw it out.

The power of a standard flying spear is not comparable to that of an arrow in the palm. When the flying spear is thrown, it crosses a space of more than fifty meters in the blink of an eye, and arrives in front of the twelfth-level winged demon. The twelfth-level winged demon Hitting it 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 shook the body of the twelfth-level Winged Demon backward. , flew upside down for more than ten meters before flapping his wings to stop his body, and then quickly caught up.

In doing so, the distance between Zhang Tie and the nearest twelfth-level winged demon suddenly increased to 100 meters away. The twelfth-level winged demon screamed strangely in the air, as if very angry. It also seemed to remind the other two winged demons flying over to pay attention to Zhang Tie's methods.

When the flying spears on the weapon racks on both sides of the cockpit of the manpower plane were almost completely thrown away by Zhang Tie, Zhang Tie finally drove the glider into the sky above the hill, and the three level 12 Winged Demons also The encirclement of Zhang Tie was completed over that hill, and when the three level 12 Winged Demons completed their encirclement of Zhang Tie, each Winged Demon was within a hundred meters of Zhang Tie.

For anyone, within this distance, no matter whether they are flying a human-powered plane or a glider, it is absolutely impossible for anyone to escape from the encirclement of the three twelfth-level winged demons.

Without the rolling hills on the ground, Zhang Tie also felt that it would be impossible for him to escape. Even those who have been silently watching this wonderful aerial chase from the ground in the distance feel that everything can be settled by this time.

However, at this moment, the human-powered plane driven by Zhang Tie finally entered the sky above the hill.

The undulating hills will form a wave-like airflow in the air. Relying on his keen perception, Zhang Tie drives the glider and starts to shuttle through the undulating terrain power updraft like a butterfly. In this shuttle, Zhang Tie The speed of the human-powered plane he was driving suddenly increased, and he threw away a level 12 Winged Demon behind him.

This is Zhang Tie's unique flying skill developed by using the characteristics of the glider, and Zhang Tie named it - gliding with the help of shear layer.

Gliding with the help of shear layers can only be carried out over the terrain with hills. The terrain dynamic updraft in these places is very special, the layering is very obvious, and the speed of the airflow is also very different. Flying in such places, as long as Continuously maneuver the glider in curves in the airflow, and Zhang Tie's speed will increase every time the glider turns.

In nature, the flying method of birds that is 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 on the sea surface. The undulating waves and terrain Bringing undulating airflow, the speed of the undulating airflow will have a drop, which is the flight basis for the shear layer to glide.

In such a flight, the airspeed lost by each turn will be less than the gain brought by the difference in airflow speed, so that speed and energy can be continuously accumulated. The acceleration process occurs when the airflow is static or low-speed and turns at a large angle into the high-speed airflow. In this process, the speed of the glider relative to the air becomes smaller, but the speed relative to the ground becomes larger. The obtained Part of the speed is lost after another large-angle turn, and then enters the high-speed airflow again to gain acceleration. In this way, the airspeed decreases-the ground speed increases-the ground speed becomes airspeed in a continuous cycle, so that the speed of the glider reaches the extreme...

Zhang Tie has never shown this kind of flying skill in front of others, because for other glider pilots, they want to be keenly aware of it while flying at high speed, and at a low altitude hundreds of meters close to the ground. It is simply impossible to see the changes and levels of the airflow speed, let alone frequently bear the terrible overload caused by the large-angle turns of the glider. Such overload, let alone a person, if the strength of the glider is slightly weak , are likely to disintegrate instantly when turning.

This kind of flying skill is completely a "magic skill" that glider pilots can't wait for.

The last time Zhang Tie was thrown into the water by a level 11 Winged Demon and lost a glider, the biggest reason was that when Zhang Tie met that Winged Demon, there was no terrain at all within a few hundred miles. It can be used, let his shearing layer take advantage of the gliding skills, which is completely useless.

But this time the situation was different. Outside Tokey City, there happened to be a vast hill for him to use, allowing him to use his abilities that had not been revealed until now.

The propeller driven by the power pedal on his feet just allows Zhang Tie to make up for his speed loss when turning out of the high-speed airflow, allowing him to 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 driven by Zhang Tie has exceeded 600 kilometers per hour, and the three winged demons chasing him were thrown away at once.

Although wing demons that use the principle of flapping wings to fly can sometimes use the airflow in the air to do some gliding movements, but their body shape depends on where they are placed. What kind of aerodynamic layout, what lift-to-drag ratio and other indicators are out of the question. In terms of the ability to use airflow, they are definitely not as good as some birds, and there is still some gap compared with human gliders, so even in the same environment, they can't catch up with Zhang Tie.

The three Winged Demons who were thrown away by Zhang Tie let out angry and ugly roars behind him. Just when Zhang Tie thought he had thrown the Winged Demons away, a powerful breath suddenly rose from the ground.

Having just felt this breath, Zhang Tie instinctively felt that something was wrong, and before he had time to react, the right wing of the manpower plane he was driving was smashed to pieces by a force.

After the right wing of the human-powered plane was shattered, Zhang Tie heard a terrifying crackling sound that broke the sound barrier.

Powerful sound hit!

As soon as this idea came up, Zhang Tie and the human-powered plane he was driving had already spun, lost control, and smashed towards the ground... If you like this work, you are welcome to vote for recommendations and monthly tickets. Your support is my biggest motivation.)
