The sun rises and the moon sets, day after day.

In a blink of an eye, Su Zimu has been lingering by the lake for more than a month, and every day in addition to practicing swords is forging his body, and his life is tense and fulfilling.

Heaven will not disappoint the hard work and sweat, and once again sink into the water, and the short stick is like a nimble fish, circling around him non-stop.

A big fish appeared dozens of meters away, Su Zimu's heart moved, and the short stick turned sharply and swam over, hitting the big fish head hard, knocking it to the surface on the spot.

Lunch is over!

Su Zimu went ashore happily.

He felt that he was proficient in swordsmanship, and he was able to handle it easily, so he rushed ashore to try, but the result was still a little worse.

Su Zimu was angry, and he couldn't wait to cut the short stick into two pieces.

Of course, it was impossible, he tried the Luoxia sword when he was bored, and the two exchanged blows, and the short stick was unscathed.

Although the force used is not large, it also proves how extraordinary the material of the short stick is.

As a result, Suda's resentment deepened.

The monk's methods didn't work, and Su Zimu had to find another way.

He found a piece of wood and carved a pair of wings for a short stick with a flying sword.

That's right, the wings.

As long as the speed of the short stick is fast enough, it can fly with the power of air, even if it is not as good as a real flying sword, it is definitely a leap forward.

It is said that the sword technique is already proficient, and there is no need to go ashore to practice.

But the resistance in the water was too great, and even with all his might, the speed of the short stick was still ridiculously slow, and it only swam instead of flying.

This is not the result that Su Zimu wants, let alone the original appearance of the sword technique.

But how can things in the world be so simple?

Su Zimu had already tried it out, and the limit distance he could manipulate the short stick was more than 100 meters, about 30 zhang.

As long as the short stick is fast enough, it can fly with the help of wings!

He couldn't wait to load the wooden wings for the short stick, and threw it like a paper airplane, and was about to manipulate the short stick to wrap around the body in a whirlwind, but he wanted the short stick to fall into the mud more happily than when he didn't put on the wings.

Drive high and go low, nothing more than that.

If you analyze it carefully, it must be that the shape of the wing is wrong!

Although Su Zimu has never been exposed to aerodynamics, he has watched all kinds of popular science books and videos from childhood to adulthood.

He flipped the stick 180 degrees and tried again, this time floating uncontrollably, then gliding smoothly for a short period of time, and finally falling due to lack of speed.

The problem was solved, and the next thing was how to modify the shape of the wings so that the short stick could fly in the air like a real flying sword.

It is impossible for Su Zimu to draw all kinds of drawings and mark all kinds of moments like a professional, he can only rely on a few memories, from simple to complex, and try slowly.

So, he put the first pair of wings aside and carved two pairs of double wings for the short sticks, one in front and one behind.

As a result, although it flew, the wing surface was too wide, so that the short stick could only fly in a straight line and could not turn at all.

Borrowing from the means of manufacturing the rudder, many holes were made in the wing, and the maneuverability was slightly better, but the practical problems were not solved.

Reducing the wing length and increasing the width has made things a little better.

Next, he put the classic models in his memory on the short stick, but he never found a suitable airfoil.

And he can only control the short stick, not the wooden wing, otherwise he can use the short stick as a model airplane.

At that time, only a pair of canard wings will need to be added, and the maneuverability of the short stick will be greatly improved.

It's a pity, unless he learns how to refine magic weapons, he shouldn't think about it so much.

After several days of experiments, Su Zimu finally found the most suitable airfoil for the short stick, that is, the through-type edge strip wing!

When this thing is installed, the short stick looks like a widened sword.

Throwing a short stick to run the sword trick, the short stick suddenly turned 90 degrees sideways, from flat flying to oblique flying, and at a very fast speed, it circled around Su Zimu, and circled again.

Like a cheerful bird!

By adjusting the angle of the inclination, he can easily control the speed and distance of the short stick.

Su Zimu didn't know what it was like to operate a real flying sword, but at this moment, he felt unprecedented pleasure, and suddenly wanted to step on the short stick and try what it was like to go straight into the green underworld.

As for those who are not frustrated, they have to fly first.

It's a pity that this thing is so heavy that you can't even take it with you, let alone fly with someone.

In fact, he has a better plan, such as directly on two pairs of small delta wings like a missile.

However, the problem of maneuvering could not be solved, so there was no way to use more complex wings, and besides, he did not do this thing to build an airplane, but only to make the short stick fly, so as to further master the sword technique.

So, what's the use of having such a complex wing?

Su Zimu originally thought that with the foundation of underwater manipulation, it would not take long to completely master the sword technique.

However, he underestimated the difficulty of this sword technique.

Without the huge resistance underwater, even the heavy short stick can fly much faster than expected, and he can control the general flight direction of the short stick, but he can't accurately control the flight trajectory of the short stick like underwater.

What is a flying sword?

It's a weapon, it's a tool, it's not a prop for a performance, if you can't even control the landing point, and you want to give a sword to the enemy on the left, but you float to the opponent on the right, what should be the matter?

Helpless, he could only suppress his temperament, starting from the simplest sword movement, and re-cultivating, not only with speed, but also with accuracy!

Originally, he didn't have any cultivation talent, and he was already a lot worse than others in internal skills, if he was not as good as others in external skills such as sword skills, what was the difference between him and a thorough salted fish?

This is still the simplest and most basic nameless sword technique, if you don't lay a good foundation now, if you have the opportunity to learn more advanced exercises in the future, do you have to do it all over again?

Su Zimu was ruthless, and he would never leave until he practiced the sword technique.

Purely out of the habit he developed in school, he made a comprehensive summary for himself.

To put it simply, carrying a sword in the water is equivalent to a guided torpedo; Carrying a sword in the air is equivalent to an air-to-air missile!

The former is slow and steady, the latter is fast and agile.

In order to improve accuracy, Su Zimu thought of many ways, first reducing the speed to strive for accuracy, but the effect was really not very good.

Not to mention increasing the speed, it is simply a large-scale rollover scene.

Later, he suddenly had an idea, first concentrated a little divine sense on the target location, and then manipulated the short stick to collide with it.

There is a divine sense positioning as a target, and the problem of accuracy is finally solved, as long as the consciousness can keep up, the short stick can hit accurately!

If you mark dozens or hundreds of navigation points in the air with your divine sense, the stick can even fly precisely along a planned route!

It's a pity that Su Zimu's cultivation is too low, and his divine sense is not strong enough, and marking two target points is already his limit.
