Lugia, my name of the elf

In fact, the sailing of a sailboat is not difficult to understand. There are roughly three situations;

The first is when the sailboat itself encounters a favorable wind, which is naturally the easiest and easiest to understand;

Just rely entirely on the power of the wind to move forward, which is also the most ideal situation.

Second, when the sailboat encounters a crosswind, the crew is required to form a certain angle between the sail and the hull;

Once the angle is formed, the sail will decompose the wind blowing from the side into two forces parallel and perpendicular to the hull, and the hull will offset the perpendicular force due to the draft.

Therefore, the other remaining force that is consistent with the direction of the ship becomes the only driving force to propel it forward.

The third and final type is headwind.

Of course, what is called a headwind is actually just another type of crosswind.

Once there is a headwind, all the crew has to do is adjust the angle of the sail so that the headwind becomes a crosswind.

From the perspective of the actual sailing route, sailing can only be as fast as lightning, twists and turns, just like walking.

Of course, in the eyes of Lugia, who has past life thinking and cognition, force analysis is naturally the most common thing;

But it is simply impossible for the people of the Storm Tribe, who are at an ancient level of civilization, to understand.

Even if Lugia comes in person and tells people that force can be broken down, it can only be analyzed after breaking down;

But no matter how Lugia explained in detail and tried to explain, it would be in vain.

Everyone who hears this argument asks this question;

What is force?

Why can force be decomposed, and what does decomposition mean?

Why on earth can ships go against the wind and still move forward? !

This is something that makes Lugia, as a god, feel powerless.

At present, the cognitive level of the tribal people is not high, and the knowledge system is not perfect. They cannot understand such a principle, which is naturally reasonable.

However, Lugia did not intend to waste such a precious historical moment in vain;

Lugia saw the three months of hard work and the hard work of every shipyard worker;

If only the people of the storm could fully understand the principle of sailing against the wind and the civilization of sailing ships could begin to flourish;

Lugia estimated that given another 300 years, he might not be able to develop to the extent he wanted.

However, Lugia intends to indirectly hand over the feasibility of "being feasible against the wind" to the people of the Stormwind Tribe;

This is different from the text and the sailboat design. What Lugia is about to do can be understood as an extreme accident and will not have any negative impact on the progress of the tribe;

Even if the people of the Storm Tribe don't know the reason, they can still use this "natural phenomenon" to benefit the tribe itself;

In the era of relying on human oars, this method of navigation is destined not to become the mainstream of the Stormwind tribe;

Otherwise, the name of Storm would be too derogatory.

Lugia in the deep sea slowly raised his head, his eyes glowing with a strange light;

His gaze passed through thousands of meters of dark water, staring closely at the new "sailing ship" located at the pier of the fourth sub-island;

At the same time, he flapped his wings slightly, increasing the speed of the reverse sea breeze on the coast at this moment;

···

The fourth island, at the pier;

"Everyone, pay attention, the wind is blowing! We have to move quickly!" Cage's old father shouted at the top of his voice, regardless of the strong sea wind blowing in his face.

"Strange, why did the sea breeze suddenly become stronger?!" Cage put down the work in his hands, faced the sea breeze in confusion, looked at the sea, and said to himself.

But the next moment, an accident that no one expected happened suddenly!

"Snapped!"

"Snapped!"

The two ropes that originally secured the ship and were tied tightly to the dock actually disconnected for some unknown reason!

"Uh!"

"what!"

"Hey?"

Due to the sudden break of the ropes fixing the ship, many boatmen who were busy on the ship lost their balance and fell to the ground.

"Ouch..." Cage also knelt down on the board of the boat, and was even more painful from the fall.

"Our oars have not been fully installed yet. Replace the two broken ropes with new ones." Seeing the sudden change, the experienced father of Cage was also calm in the face of danger and ordered calmly.

But at this moment, no one noticed;

The hull has formed a certain angle with the wind direction, and the huge hemp cloth bound to the two wooden poles has also formed a certain angle with the hull and the incoming sea breeze.

"Snapped!"

Another rope fixing the ship broke.

"What the hell does this happen?!"

"Is the rope damaged by moisture? No, it's obviously a new, dry rope. How could it break so quickly?!"

"...."

Many boatmen were confused when they saw another broken rope.

"No, the previous rope break might have been a coincidence, but the break of the rope just now was caused by our boat!" The speaker was Kai, who stood up again after falling and was calmly observing everything by the side of the boat. strange.

"Been pulled apart by our ship?!"

"Cage, you see clearly, we haven't set sail yet, how can the ship pull the ship apart..." Another boatman who refuted Cage's point of view had not finished speaking. The next moment;

"Snapped!"

Another rope fastening the ship snapped;

Not only that, what shocked everyone on the spot was that the ship at this moment was actually moving towards the sea as Cage said;

"What's going on?! Why does the ship move on its own?!"

"Aren't we in headwind? Why is the ship moving forward?!"

"Wait, damn, is there a sea monster causing trouble below? Do we need to call soldiers to help?"

At this time, when he saw the ship moving toward the sea with an incomprehensible force and breaking free of the last remaining ropes, even Cage's father, who was the most experienced, was stunned and was too shocked to speak. In one sentence;

Among this tribe, the greatest shipbuilder in history cannot understand why the ship is moving forward despite the headwind? !

But while everyone was shocked and confused, Cage remained silent. He suddenly noticed something that everyone ignored;

That is a new type of ship. It seems that it does not go straight against the wind, but deviates to a certain extent against the sea wind;

The young man raised his head again and glanced at the huge hemp cloth, also paying attention to the special angle formed by it.

At this time, even if the young man still didn't understand, he understood that this was not the trouble caused by some elf.

Cage took out a stone hammer and a knife from his back, tapped on the ship's plank, and recorded what he thought was the most important thing.

"Perhaps, the ship will move forward when the angle between the ship and the sea breeze is at this angle. There is also the angle between the huge hemp cloth and the sea breeze, and the angle formed by the ship. Well, I have written it all down." Cage showed a surprised smile. , he has carved two special angles on the ship board.

···

"Haha, I really saw the right person..." Lugia looked at Cage who was so wise and nodded with satisfaction;

He is becoming more and more confident in his own vision of people.

Now, once the Storm Tribe discovers the magical "natural phenomenon" that is possible against the wind, its shipbuilding industry and navigation technology will make rapid progress and development.
