Castle of Black Iron - Chapter 605

Chapter 605: The Eagle Broke Its Wing
The crisis came so abruptly . The wing demon had already been 100 m away from Zhang Tie when Zhang Tie caught sight of it .



Zhang Tie released two palm bolts and changed the direction almost at the same time .

Although palm bolts caused sonic booms, they were useless to LV 12 wing demons . They could only slightly slow down the wing demon's flying speed before being dodged away by the wing demon .

In a split second, Zhang Tie had already exerted his utmost effort to step on the pedals as fast as possible . Meanwhile, he had the man-powered plane cut into a downward strand of cold air flow on his left and dive towards the ground .

Zhang Tie understood that he could never defeat a LV 12 wing demon in the sky . Last time, he was embarrassed by a LV 11 wing demon, not to mention a LV 12 wing demon .

The wing demon chased after him as it uttered a weird, frightening sound . When Zhang Tie started to dive towards the ground by the man-powered plane, that wing demon had already been less than 80 m from him . Sitting in the cockpit, Zhang Tie inclined his body as he cast another palm bolt backwards . The wing demon blocked it away with an odd-looking fork . However, In such a delay, Zhang Tie was pushed 10 meters away .

At the critical moment, Zhang Tie recovered his composure at once as the terrain of the Tokei City, the capital of Titanic Duchy appeared in his mind immediately . . .

Zhang Tie knew that he could only use three aspects to escape; mountain, water and his man-powered plane .

There were undulating hills in the east of Tokei City . Much elevating wavy air flows formed above the hills due to the terrain . In the elevating wavy airflows, Zhang Tie could use a unique flying skill to gain a speed which was far greater than that could be gained in normal conditions .



After flying over those hills, there was a huge lake more than 300 km away in the east of the hills . The lake was about 200 km in both length and width . It was called Star Leaves Lake . It was the biggest freshwater lake in the Titanic Duchy . As long as he arrived there, he would have a greater chance to escape even at the cost of one man-powered plane .

Although Zhang Tie could not defeat a LV 12 wing demon in the sky, he was unrivaled in water .

In a split second, Zhang Tie had dived from 10,000 m to 3,000-4,000 m in height . Through sharp frictions with air flows, the rapidly running propeller uttered a weird wuthering and deafening sound .

Zhang Tie then released some more palm bolts to further slow down the speed of the wing demon . However, during this process, that wing demon narrowed the distance to 60 m .

If it was the former glider that Zhang Tie drove, Zhang Tie might have been caught up by that wing demon . This time, the extra driving force provided by the propeller of man-powered plane postponed the time of being caught up by the wing demon for Zhang Tie .

Facing chilly wind, hearing weird, wuthering sound from the propeller, Zhang Tie could see the objects on the ground below him more and more clearly . Zhang Tie found that the dense military camps and demonized puppets on the ground became more terrifying; however, he didn't have time to observe them at all; instead, he only thought about how to escape .

When the contour of hills entered Zhang Tie's vision, what Zhang Tie was most concerned about happened . Two more purple black points were accelerating towards him from the front and on the left .

"Three LV 12 wing demons? What the hell?"



"F*ck!"

Zhang Tie instantly picked off a standard javelin from the weapon rack hanging on one side of the glider and threw it towards that wing demon behind him .

Standard javelin's power could never be matched by palm bolts . Almost in a wink, it had flew over 50 m and arrived in front of that LV 12 wing demon . The LV 12 wing demon instantly blocked it away with its fork, causing a huge sound . However, that wing demon was also sent flying backward over 10 m while its body quivered .

In this way, the distance between Zhang Tie and the LV 12 wing demon was expanded to over 100 m at once . The LV 12 wing demon uttered a weird sound in the air, which sounded being extremely furious and warned the other two wing demons about this trick .

When the javelins on both sides of the cockpit were almost used up, Zhang Tie finally cut into the air territory above the hills . Three LV 12 wing demons accomplished their encirclement above the hills . Each of the 3 LV 12 wing demons was less than 100 m away from Zhang Tie .

In this distance, nobody could escape out of 3 LV 12 wing demons' encirclement, no matter what he drove, the man-powered plane or a glider .

Without those undulating hills, Zhang Tie felt that he could never escape . Even those who were watching this wonderful air chase from the ground in the distance felt that the result was already fixed .

However, at this moment, Zhang Tie's man-powered plane finally entered the air territory above the hills .

Undulating hills could produce wavy airflows . Based on his acute senses, Zhang Tie started to penetrate through those elevating airflows like a butterfly . Zhang Tie's plane suddenly accelerated, expanding the distance between him and the LV 12 wing demon behind him .

This was an exclusive flying skill that Zhang Tie developed based on the traits of the glider . Zhang Tie named it dynamic soaring .

Dynamic soaring could only be applied in the air territory above the undulating hills . Such area bred very special elevating airflows and a strong sense of space hierarchy . The airflows were sharply different in speed . By constantly making curvilinear motion among these airflows, Zhang Tie would accelerate its glider each time he made a turn .

In the mother nature, this glider's driving skill was very similar to that of seagulls' flight principle among waves . The undulating hills were like undulating waves as they could produce undulating airflows in different speeds . This was the principle of dynamic soaring .

In such a flight, the space velocity lost in each turn would be smaller than the increasing speed brought by different air flows . In this way, speed and energy could be constantly accumulated . When the air stopped flowing or the glider entered high-speed airflows from the low-speed area after a great turn, the glider's moving speed decreased compared to that of airflows; however, it increased compared to the ground . After another sharp turn, a part of increasing speed was lost . After entering high-speed airflow, it gained a momentum once again . Similarly, through the circulation of decreased airspeed —— increased ground velocity——ground velocity turning into space velocity, the glider reached the highest speed .

Zhang Tie had not shown off this flying skill in front of others . It was almost impossible for other glider drivers to sense the changes and layers of air flow at hundreds of meters in height when in high-speed flight; not to mention that they had to frequently bear the terrifying overload caused by the large-angle turn of the glider . In the process, if the glider was poor, it might break into parts when turning, not to mention humans .

Such a flying skill was completely an unimaginable "marvelous skill" of the glider drivers that they could never master .

Last time, Zhang Tie dived in water to escape a LV 11 wing demon at the cost of a glider because he had no terrain to make use of within hundreds of miles when he encountered that wing demon . As a result, he could not apply his dynamic soaring skill .

However, this time, it was a different situation . He could make use of the vast, undulating hills and expose his special skill . There was always a way out!

The driving force provided by the propeller could mend up the losing speed when he moved out of the high-speed airflows, allowing him to cut in high-speed air flows at a faster speed . Benefited from this, he could gain a higher speed . After accelerating a few times, the speed of Zhang Tie's man-powered plane had already surpassed 600 km, expanding the distances between him and the other three wing demons at once .

Although wing demons could do some gliding motions using airflows by flapping their wings, they could not meet the requirements of aerodynamics . They could never match some birds on the application of air flows, even human gliders . Therefore, even in the same environment, they could not catch up with Zhang Tie .

At this moment, Zhang Tie heard furious roars behind him . When he thought that he had already dodged from their chase, a powerful qi rose from the ground .

When Zhang Tie sensed this qi, before he made any response had the right wing of his man-powered plane been broken into pieces by a strength .

Soon after that, Zhang Tie heard a terrifying air-torn explosion .

"What a sonic boom!"

The moment this whim flashed across Zhang Tie's mind had his man-powered plane swiveled and lost its control as it dived towards the ground . . .
