Spatial Channels and the Second Fiendfyre Flight

Regulus spread his Guardian Will into the surrounding space.

First, try inviting it, like we did at Hogwarts, by bringing the Guardian Image out of the Spiritual World and placing it into the space with good intentions. The space neither responded nor rejected it, because the space here has no will.

Acceptance and rejection are non-existent concepts for it; it is empty.

He stopped inviting people and simply integrated himself into the group.

The Guardian Will surged forth, without any probing or benevolent guise, pushing directly into the surrounding space.

It went in with a single push, without any resistance.

The Guardian Image permeates the surrounding space, the space embraces it, and the Guardian Will becomes an attribute of the space itself.

Regulus sensed the space around him.

Unlike Spatial Perception, which detects something, space itself provides feedback to it.

Within a radius of about five or six meters around him, the space became an extension of him.

The flow of the wind, the air currents created by seagulls flapping their wings as they skim over the cliff, the swaying of withered grass leaves in the wind—all these are clearly perceived, as if the senses are integrated into the environment, and the environment itself becomes his perspective.

He twitched the corner of his mouth slightly.

What took so long at Hogwarts took only a few minutes here.

I see.

The problem was never with him; in a different natural environment, everything made sense.

Regulus began testing the application.

First, there is Spatial Folding.

He held his wand in an arc with one hand, executing the standard gesture for Spatial Warp, completing the three steps from sensing the target to guiding the folding of Magic Power and stabilizing the passage. He then directly pinched a small area, shortening the distance between the two points.

Performing this operation at Hogwarts would present some spatial resistance, requiring a continuous infusion of Magic Power to maintain.

Here, once you fold it and release your hand, the space remains folded and doesn't spring back; no extra force is needed to hold it down. It's effortless, but not effortless either. The Magic Power of folding itself is consumed the same; what's saved is the energy required to maintain it.

Then there are Spatial Anchor.

He set up two anchor points in the space, one under his feet and the other next to a rock ten meters away.

The anchor point is steady and secure, the space is neither contested nor contested, whatever he places there will be accepted.

At Hogwarts, the anchor point needs a constant supply of Magic Power to maintain itself. The Castle's space is flexible, constantly pulling the anchored area back, and he has to hold it down firmly.

He could do the same at Hogwarts. The Castle's space wasn't exactly friendly to him, but it wasn't so bad that he couldn't even set up an anchor point.

There, the anchor points support a Spatial Network, a closed-loop channel for the flow of spells, not a place for people to walk.

Things are different now. The Guardian Will has merged into the space here, and the space itself has acquired the attribute of Protection.

If he folds the space between the two anchor points, the Guardian Will will can fill the gap in the fold and support it.

Previously at Hogwarts, spells could only travel through the network because they weren't afraid of getting stuck halfway.

People are different; people need absolute stability, and now that we have the Guardian Will them, this premise is established.

He increased the distance between the two anchor points to twenty meters, thirty meters, and fifty meters.

He then opened a Spatial Channel between the two anchor points.

After Spatial Folding, the distance between two points approaches zero, so theoretically, you can cross the distance in one step.

But the folded space has thickness, and the area stretched open by the Guardian Will is more like the extremely narrow slit between two mirrors joined together. He Guardian Will the anchor point fifty meters away, corresponding to the anchor point under his feet, and then activated the Spatial Folding.

The two points fit together.

From the outside, it looked like a crack standing upright in the air.

It was about the height of a person, with irregular edges, and a faint, silvery-white, soft glow, originating from the same source as the light of his Patronus.

Looking through the crack, you can see rocks and withered grass on the other side, and the sea further away.

The image was shaky, like looking through a heatwave.

The two places overlapped, separated by a step.

He looked at the crack, his Magic Perception and Spatial Perception covering it together to examine its structure.

The passageway was enveloped by Guardian Will, with a silvery-white glow evenly distributed on the inner walls, without any weak points.

The interior space is well supported and shows no signs of collapse.

The Guardian Will filled the gaps, and the space itself gave him feedback: stability, security, and an indescribable sense of peace.

His Protection will, of course, Protection him.

Then he let Starry Sky Kite wear it first.

On the distant sea, the Starry Sky Kite turned around and flew back, folding its wings and swooping down, its Silver Light condensing into a line that crashed straight into the crack.

The moment I entered, Silver Light seeped in from the edge of the crack, illuminating the entire crack for a moment.

Then it emerged from the exit at the other end, its wings unfurled, circled above the rock, landed, and tilted its head to look at Regulus. Regulus stepped inside.

There's a solid feeling beneath my feet; I'm standing on a space supported by the Guardian Will, with a sense of support.

The inner walls on both sides are glowing, a soft, silvery-white light, through which the texture of the space itself can be seen.

Like creases left after space has been folded, fibrous and finely interwoven, the translucent gray cracks, illuminated by the silvery light, were narrow, about two steps wide, revealing rocks, withered grass, and a gray-blue sky fifty meters away from the exit ahead. He took a step.

The exit unfolded before my eyes, and with another step, I was already standing next to the rocks fifty meters away.

He looked back and saw that the passage was still there. He could clearly see the edge of the cliff and the grass on the other side of the entrance, as if looking out from a picture frame through the silvery-white crack.

He took one step and was there.

Regulus fell into thought.

If this passage can be secured, it becomes a door; wherever anchor points can be placed, the door can be opened.

Unaffected by Anti-Apparition Charm, requiring no fireplace network, no Portkey, and leaving no traceable Magic trail, it is entirely private. If the distance can be extended to the level of intercity travel, this is a teleportation network exclusively for him.

If the passage can be fixed, it will become a permanent strategic node, and its depth capability will be terrifyingly strong.

You can open one in Grimmauld Place, one in Hogwarts, or even one in the Ministry of Magic.

All Ministry of Magic, one for each.

Currently, only he can go on his own because the Guardian Will only recognizes him. But if this restriction is lifted in the future, allowing others to pass through as well, then that would be a military-level strategic airlift capability.

Imagine a hundred wizards entering from point A and simultaneously emerging from point B, with no intermediate steps—they start fighting as soon as they land. Who could withstand that? What if they were further away?

There is no upper limit to the distance of Spatial Folding; as long as there is enough Magic Power and the anchor point is stable, it can be folded to any distance.

In theory, doors could also be opened between planets.

But that's too far; he can't even leave Earth right now.

Regulus noted the direction, stopped thinking about it, removed the anchor point, and the passage disappeared.

The silvery-white crack in the air closed up, stitched back together, leaving no trace, and the space returned to its original state.

Baruk poked his head out of the inner bag, his eight amber eyes fixed on the spot where the passage had disappeared, and his chelicerae clicked.

"Road?"

Regulus patted its spider head and nodded.

"Road."

The matter concerning the space has come to an end.

Regulus stood there for a while; the wind was strong, blowing his hair back.

Once you leave Hogwarts, the path opens up.

His abilities hadn't reached any new level; it was just that the Hogwarts environment was constantly weighing him down.

Some things can't be done simply because the location is wrong.

But on the other hand, if one day the space of Hogwarts were willing to cooperate with him, he could do far more in the Castle than here. The space of Hogwarts has a will and a thousand years of Magic accumulation. If it actively cooperates, it is a powerful partner actively working together, which is completely different from an empty container passively receiving.

That would be something on another level.

However, Dumbledore still alive, so it's not his place to worry about the headmaster's position.

The headmaster of Hogwarts is appointed by the Board of Governors; it is not a system of succession, nor is it a system where might makes right.

At least not now.

That's thinking too far ahead.

It's time to fly.

Regulus stretched his shoulders and wrists. The spatial test had taken a toll on his mental energy, but not much. After resting for a while, he had almost recovered.

He looked at the Great Sea before him, its grey-blue surface stretching to the horizon, the clouds hanging low, and the wind blowing from the west.

In the distance, several seagulls circled on the crest of the waves, gliding motionless with their wings.

Last semester, he flew over the Forbidden Forest for the first time using Fiendfyre. He used his Shield Charm to create a shell, and then spewed Fiendfyre backward to propel himself forward.

It can fly, and it's fast, but it's rough.

Unstable direction, relying on Magic Power to force turns, the relationship between thrust and airflow was guessed entirely by intuition, and the Shield Charm vibrated at high frequency when approaching the speed of sound, almost falling apart.

Now I have more things on my mind.

He hadn't read those books in detail yet, but he had skimmed through the basic concepts of Aerodynamics.

Lift, drag, airfoil, angle of attack, thrust line, sweep angle, shock wave, wing loading, induced drag, aspect ratio.

He didn't need to build a real airplane; he only needed to transform the outer shell of the Shield Charm from a push-along shell into a shape that could cut through the wind. He first cast the Shield Charm, the Magic Power spreading out and beginning to shape it.

The front end is elongated and pointed, and the cross-section of the head changes from a circle to an ellipse, with the curvature of the upper surface being greater than that of the lower surface.

The classic airfoil, convex at the top and flat at the bottom, operates on the most basic lift principle: airflow travels faster on the upper surface and slower on the lower surface, creating a pressure difference that generates lift.

The short wings on both sides have been lengthened, and the wingspan is almost twice as wide as before. The wing surface has been curved, the leading edge is rounded and blunt, and the trailing edge is thinned and tapered, with the airfoil in the shape of a teardrop.

By increasing the aspect ratio, lift efficiency increases, while induced drag decreases.

The tail section features both a horizontal tail and a vertical tail. The horizontal tail has a different installation angle than the main wing and is used to balance the pitch moment, while the vertical tail is responsible for directional stability.

The nozzle was moved from directly behind to a slightly lower position, the thrust line passed through the Flying Device's center of gravity, the point of thrust application was aligned with the center of gravity, the torque generated by the thrust approached zero, and the direction became stable.

A narrow slit is left at the wingtip and the trailing edge, with an adjustable opening, which is equivalent to a simplified version of flaps and ailerons.

By adjusting the gap opening to regulate the local airflow velocity, a lift difference is generated, enabling roll and yaw.

He cast two spells on himself: Shock Absorption Charm and the other to Anti-G Charm.

Last time, when it flew to over a thousand, its internal organs were almost crushed. This time, it added an extra layer to distribute the inertial load as much as possible throughout its body. Fiendfyre surged from its palms, orange-red flames churning, dark patterns flickering within the tongues of fire. Heat was drawn inward, and the surrounding air was drawn towards the flames.

The Fiendfyre filled in, flowing along the inner wall of the Shield Charm, sinking to the bottom, and gathering at the nozzle.

The internal pressure has increased, but the stress distribution on the outer shell is much more uniform than before, and there is no feeling of localized overload.

take off.

The Fiendfyre ignited, and a jet of orange-red liquid shot out from the tail, propelling it upwards.

The feeling is completely different.

Last time I took off, I was pushed along by the thrust, and it was difficult to control the direction. This time, the lift and thrust were separate.

When the wing surface cuts through the wind, the airflow splits into two paths at the leading edge and merges at the trailing edge, creating an upward force due to the pressure difference.

The Fiendfyre pushes forward, generating a forward force.

The two forces act independently in different directions; he only needs to adjust their ratio.

He flew at a low speed for a while, close to the top of the cliff. The sea breeze was blowing in from the side, and the angle of attack of the wing changed with the airflow. He used Magic Fine-tuning the curvature of the wing surface and stabilize the lift.

Then accelerate.

As the wingtip slit narrows on one side, the airflow on that side decreases, resulting in significantly more lift than the other side. This lift difference causes the entire Flying Device to tilt towards the side with lower lift, thus changing its direction.

Turn.

The wing surface carried the weight itself, smoothly and stably, with a turning radius less than half that of the last time, and no sideslip or stall.

He circled once above the cliff, then again, the second circle being 30% faster than the first, the wing surfaces responding accordingly.

The angle adjustment directly corresponds to the lift difference, precise and immediate, a completely different thing from the brute force of relying on Magic Power to steer the direction last time. He tried a dive and pull-up, nose down, thrust off, letting gravity accelerate, the sea surface rapidly magnified in his field of vision, and the rock textures on the cliff face were clearly visible.

Then the wing angle of attack increased, lift surged, and thrust restarted, pulling the entire Flying Device up from its dive, tracing a clean arc, and flying back to its original altitude.

The moment it was pulled up, the overload pressed down, and my body sank into the seat. The Shock Absorption Charm and the Anti-G Charm worked at the same time, dispersing most of the load, but my stomach still jolted.

It can withstand it.

Regulus began to accelerate.
