Wizard: I brought the wrong system

The effect of 'Feather Fall' can be summed up in one word: 'enhanced wind resistance'.

In a windless theoretical environment.

If you don't move, even if you use Feather Fall, it won't have any effect.

If the body falls downward, it will strengthen the wind coming from below.

If you are running forward, what is strengthened is the wind coming from the front.

And the faster the speed, the stronger the enhanced wind will be.

How to use the obviously negative wind resistance?

"The duration is only about ten seconds, and it cannot be used for weight-bearing exercises."

It seems...it can only be used for landing and braking?

"Light, trip, and mist are changed to Sun Fist, Instantaneous Body, and Fog Body. This is another usage of spells."

"Among them, the casting process of the Sun Fist and the Fog Body Technique are similar. They both compress the magic power of the spell, allowing the effect of the trick to explode suddenly in a short time."

"Can this kind of thinking be used in Feather Fall?"

Wind Profound Truth - Sudden Braking?

"That's not true. The effect of Feather Fall is to strengthen wind resistance. No matter how much magic power bursts out in a short period of time, it can't have more impact on wind resistance. Therefore, it is difficult for 'Feather Fall' to achieve the effect of 'sudden braking'."

The idea of ​​saving and bursting cannot be used on the 'Feather Falling Technique'.

"The 'tripping technique' was changed to 'snapshot technique', and the emphasis was on 'proper', which happens to transmit the power of the tripping technique to the legs at the moment when the legs exert force, and at the same time build a perfect force platform."

"Can this idea be used in 'Feather Fall'?"

Wind Profound Truth—Sudden Movement and Sudden Stop?

"Sudden stop cannot be achieved in the first place, even if the 'feather fall' is used 'properly', the deceleration process cannot be skipped."

Yarrow's thinking has become a mess, but he always feels that there is definitely room for digging in the 'Feather Fall' technique.

How should it be changed?

Yarrow stood up and paced back and forth by the fire, feeling the slight trembling from the fluff, and asked ourselves: "Where is the direction of modification? Why do I think that there is still room for digging in 'Feather Fall'?" Woolen cloth?"

Naturally, no one answered this kind of self-question, so Yarrow had to continue to dig out items related to wind in his memory.

"What are the things related to the wind?"

"Wind, wind... a kite?"

"airplane?"

"sailboat?"

Yarrow's eyes lit up, and he clapped his hands fiercely: "By the way, sailing boat!"

"Sailing can go against the wind - Bernoulli's principle!"

Yarrow sat down quickly, took out a pen and scrap of paper from the space, and quickly recalled 'Bernoulli's principle'.

[In a fluid system, such as air flow and water flow, the faster the flow rate, the smaller the pressure generated by the fluid]

[Sailboat is to make the sail form an angle with the frontal wind, so that one side of the sail shows a "concave" and "convex" surface]

[The speed of the wind flow on the 'convex' side will become faster, and the pressure will become smaller. The wind flow on the 'concave' surface is normal, and the pressure is high]

[The pressure transfers 'force' from high to low, thus generating thrust in the opposite direction]

After writing these words, Yarrow recalled the scene of taking the sea boat before, and immediately thought of a key question.

"A sailing boat can't go completely against the wind when going retrograde. Instead, it chooses to form an angle of about 30°C with the wind and face the wind head-on. Not only will it not be able to generate forward propulsion, but the 'convex' front section will suffer greater wind resistance. The propulsion is on the ninety-degree side."

The wings of the hang glider use the 'Bernoulli principle', the wings are facing the wind directly, and finally generate an upward lift.

It's not that this lifting force is useless, it's just that if the transmitted force is useless to help the forward direction, then this structure cannot be applied to the 'Feather Falling Technique'.

Because the effect of 'Feather Fall' is to 'enhance wind resistance', if the direction of oneself changes, the direction of 'wind resistance' will naturally change as well.

In the process of running in a straight line, if there is a sudden force transmitted from the vertical direction, it will not only be difficult to maintain the center of gravity of the body, but also easily sprain the ankle and increase the possibility of falling.

This trick was released by Yarrow himself. He could indeed predict in advance and tense his ankle muscles against this force, but what would be the use of doing so?

Just to exercise the ankle muscles?

Of course, you can also use this power to steer, but it's still the same sentence: the effect of the 'Feather Falling Technique' is to 'enhance wind resistance'!

When the body rotates, the direction of wind resistance will also change. In other words, the force generated by the "Bernoulli principle" will also be deflected.

This force is always at a ninety-degree angle to the force of inertia!

That is to say, before the inertial force is exhausted, the body will spin wildly like a spinning top being constantly whipped!

"What's the use of this?"

Yarrow felt that he still hadn't found the inspiration that wandered in his mind.

Just when he was about to tear up the straw paper, his eyes turned away from the straw paper, and his hand suddenly stopped.

"Wait... Turning the inertia of sprinting into the power of rotation, isn't this the Judgment of Galen, the Whirlwind of the Barbarian King, and the Bladestorm of the Warcraft Sword Master?"

Yarrow's inspiration exploded, and he kept writing on the straw paper.

"As long as the sprinting power keeps on, the lateral force transmitted will not stop, and it will keep spinning."

"As for the ankle problem...you can directly learn from the top. As long as the body turns quickly, you don't need your ankles to maintain balance at all. You can directly stand on your toes and use your toes as a balance point."

"No... this won't work. If you keep spinning, the internal organs will also bring inertia, especially the brain, which is very likely to cause dizziness. Even a little dizziness in close quarters is very fatal, so you can't keep spinning indefinitely."

"It's best to use it at the end of the rush, rotate it one or two times...or even half a circle, convert the impact force into rotation force and chop it out."

"In this way, you don't need to use your toes as a bearing point, and you can directly step on the ground."

"If this is the case, then you can integrate the power-generating skills of the gibbous moon and full moon in the Arc Moon Sword Art, and you can also activate the power core of the Raging Fire Epee, and continue to increase the power of the horizontal split!"

"By the way, this is a perfect match with the instant body technique!"

"If you are sure that you can definitely hit the enemy, you can even use the 'Two Instant Body' directly, so you don't have to worry about your body being unable to bear it!"

Although the speed produced by the second instant body exceeds the limit of Yarrow's body, if it can hit the enemy, a large part of the inertia will be directly converted into the force of the horizontal split, and all of it will be vented on the enemy. The remaining inertia will naturally not pose much threat to the body up.

"Not only that, but the 'half body attack' can also use this move to unleash a powerful slash!"

……

After Yarrow finished his modification, he looked at the move written on the straw paper and began to think about the name of the move.

"Once the body stops and the inertia disappears, the power of rotation will stop immediately."

"It is very different from Galen's Judgment and Warcraft Sword Master's Blade Storm, but it is more similar to Whirlwind."

"At the same time, this trick also borrows the magic power of the wind... just call it 'whirlwind'."
