The three men crossed the caged mountain and turned to the west, all the way to the desperate mountains.

Less than half an hour later, Maisie was defeated first.

In the 1,500-meter airspace, Phoenix easily flew 400 kilometers per hour with two engines.Although Maisie's petrel form can reach this speed, it can only persist for a short time, and it is sooner or later to be thrown off in the face of the tireless new 14-cylinder engine.

“How?”Tilly covered her mouth.

“I can fly...I can fly!”Maisie was already breathless over there.

“You’ve done your best, so let me go.”"

The lightning took the uncompromising partner into his arms and took over the second phase of the test.

One man and one machine began a new pursuit in the gray sky.

The scenery at the foot shrinks, and the mountains separating the human kingdom have gradually become a winding ink line, and Tili can see the red mist flowing from the direction of the spine of the mainland in the distance above the eternal winter and the wolf heart, like a layer of turbid barrier.The earth in the barrier is undoubtedly filled with scarlet, but as long as it can wash up the sky, it can see the real world again.

“Is that your limit?The sound of lightning sounded, “I can fly far faster than this!”"

In terms of flight speed alone, the other party's ability is really unattainable, even if it is the lord of the sky with the power of transmission, he has also suffered a loss in her hands.

But for Tilly, winning is not the most important thing.

Driving this huge but flexible machine and bringing its performance to the limit is already a pleasure.

She took back the view from her, smiled slightly, pulled up the nose, and flew toward the higher airspace.

The lightning also followed, and always remained in the front of the plane about 100 meters.

According to the introduction in the manual, the Phoenix has been the technical optimization of the dream world, and the key parts are also processed by Anna himself, which itself has far more than the basic quality of the sky fire - the flight speed can reach 550 kilometers per hour, the maximum range is more than 1500 kilometers, and the twin-row star engine also adds a turbine system, which makes it impossible to achieve the performance of more than three kilometers of airspace, which is not a big attenuation.

However, this is not the biggest feature of the Phoenix.

Its body structure has been jointly strengthened by candlelight and Doris, strength and durability can be said to be on the material itself, can be regarded as the first industrial technology and magic combined with the aircraft.

Tiley knew that the propeller was the most efficient at low speeds, and as the speed increased, its propulsion efficiency would be rapidly reduced, so it was almost impossible to touch the back of lightning on its own power alone.

She must help with other forces.

After lifting to a height far away from the clouds, Tily jerked the throttle to the maximum and pressed down the joystick.

The engine was so loud!

The Phoenix turned sharply and entered the subduction state.

In order to keep herself in the forefront, the lightning also followed the adjustment of the direction of rapid fall, just to avoid mutual influence, she pulled the horizontal distance to about a kilometer, vertical direction is still the same 100 meters gap - at this height and speed, the magic tone of the "light film" has been very obvious, a shining ripple around her to form a protective layer, in case she is affected by cold wind and low pressure.

Undoubtedly, the magic of lightning in the state consumes far more speed than it does during normal flight.

Even Roland mentioned during the test ability that the lightning cannot be in a supersonic state for a long time, it is likely that the flight itself requires too much magic, but that the consumption of magic in the extreme environment of the body is greatly increased.

As a result, she rarely gets into the speed of sound when she patrols.

For witches, the magic of free space is a very dangerous thing.

Of course, at this moment, Tiley was not very good, the thin air in the high air made her breathe very laborious, the full speed of the engine and the rushing wind made the noise and tremors rise in the cockpit, and there was no magic to the same protection, she could only rely on the body to harden.

According to the airspeed watch, the Phoenix has approached the speed of 800 kilometers per hour.

This is significantly beyond the upper limit of its speed.

Although the lightning is still stable in front of the nose, it has not been able to talk to her with the listening print.

That’s right, what Tilie is going to borrow is gravity.

Before driving the biplane, she found that when she converted the accumulated height into speed, she could easily break the limits of the aircraft.

However, the risk of this velocity cannot be ignored, and the light cannot be lifted again, and the weight is directly in the air.

If it hadn’t been for her ability to sense that tipping point, she would never have boldly used subduction to speed up during test flights.

But even so, the chances of catching up with lightning are slim.

She remembers Roland saying that due to the paddle principle, the piston aircraft would cost a lot more than the speed of sound, in other words, it would not pay for it, so that the jet engine soon replaced the propeller after it came out.Lightning can break through the sound barrier at any time, and the gap between the two is not on one level.

So she needs help with something else.

As the height rapidly dropped, the dense dark clouds in the 2,500-meter airspace hit the two like the earth.

The phoenix whistled into the dark cloud and splashed a "fog column" on the clouds!

At this time, the speed of the aircraft has exceeded 900 kilometers per hour, and the tremor began to spread from the air to the wings, and she could feel the wing surface cut open the thick air flow in front like a blade, and this high-speed friction made the air no longer a nihilistic thing, but like a thick wall.

The lightning disappears into view.

Tilly knew the opportunity had come.

She focused all her attention on the plane’s maneuvering—the thrust that the propellers at a speed offered almost as much as the drag—and what ordinary people should think about was how to pull the plane back up rather than let it dive faster.Only Tilly can maintain precise control in the case of such severe tremors and use rudder surface adjustments to further increase the speed.

Although the acceleration is not large, it is close enough to close the distance from the frontrunner.

When the Phoenix's own limit approached, she set up a plane rushed out of the clouds!

The earth is re-emerging in its eyes.

At the same time, there is lightning - compared to the previous stable 100 meters lead, she is now on the same level as the new aircraft.The conscious latter instantly entered the speed of sound, but soon slowed down again and turned to the side of the cockpit of the aircraft.

"It is indeed the eldest princess," said the lightning in not much depression, but more sighing, "you can take the clouds into account.""

"If it's a little bit thinner, I won't be able to catch up with you."Tilly flattened the fuselage while laughing back.

From the beginning, her plan was to use natural subduction to allow the lightning to adapt to a steady acceleration, and finally to complete the supernd under the shadow of the dark cloud - although only for a moment, the Phoenix did close the gap.

“Wait, where did we fly?Maisie poked her head out of the lightning bosom.

“Uh...” Tilly looked around and found a strange view below, and the desperate mountains were already far behind them.Just now the pursuit is too much investment, did not notice how far all the way to the northwest, "probably here is also part of the fertile plain?" 」

"It must be wrong," said the lightning, drawing out the lookout, "but the fertile plains that have never been involved before."If we extrapolate according to the route, our east side should be at the junction of the wolf-heart and the kingdom of eternal winter, and in front of us is the continental spine—”

Speaking of which, she suddenly stopped.

“What happened?”

Tilly looked in the direction she mentioned, and then stood in the same place.

The mountains hidden in the clouds in the distance are far more magnificent than the desperate mountains, but because they have long known its existence from the mouths of Agersha and the expedition, it will not be too surprising to see it for the first time.

What shocked her was the mountains.

I saw a gloomy, dull dark red cloud perched on the top of the mountain, and countless electric lights flashed among them, like a storm of blood.

There is no doubt that it is not an celestial body that can be formed by nature.

The red cloud made her feel very uneasy.
