The ship is done, and on the issue of power, since there is a precedent for building the hull, Brother Tiannan has also begun to use his imagination, as the owner of the system, he is also a level 9 high priest, in fact, he himself meets the prerequisites for research.

When the interest came, Brother Tiannan naturally wanted to make a good mess, so he directly asked Ajuan and the others to rest, and he himself sat on the edge of the workbench and started to get busy.

It just so happened that there were two curious girls next to them, and now it happened that men and women were not tired of working, Tian Tiannan asked Xiaoxiao and Helian Jiaojiao to be responsible for catalyzing the trees, and he was to let Miao Miao assist, and the four of them were engaged in the construction of new ships.

"Miao Miao, you're like this..." Regarding the internal structure of the ship, Tian Tiannan already had a draft, but because it was a meticulous job, he told Miao Miao his ideas and asked his sister to complete it.

Then he himself began to burn his brain on how to solve the problem of motivation, and today Ajuan and the others completely opened a new door to Brother Tiannan, and while secretly regretting why he couldn't think of it before, he was also extremely excited.

The biggest difference between humans and animals is that people know how to make and use tools, when I was a child, I had a dream of becoming a scientist when I grew up. What kind of structure is it? No matter what class of people are, they always have a great interest or yearning for "invention and creation", but the difference between success in the end lies in whether they have put it into action or not.

And at this moment, Brother Tiannan is a person who is in action, driven by great interest, and he already has this condition or ability, he has been making up for a while, and fighting for the dignity of an otaku for twenty years, he has succeeded!

For more than an hour, Brother Tiannan, who was sitting on the ground scratching his ears and cheeks, suddenly stood up, took out the Qingyang cane, took the sacrificial source crystal, and let the ground poke it.

"Hum..."

The faint golden light shone, and several vines that were not thick emerged from the ground in front of him, originally shaking irregularly, but then under the manipulation of Tian Tiannan, they began to weave.

Gradually, a finished product appeared in front of me, and on top of it was a basin-sized bird's nest altar, which was obviously inspired by the bird's nest altar in Red Nine.

Underneath the Bird's Nest Altar is a cuboid part with a "flower" about the size of the Bird's Nest Altar behind the cuboid part, connected to it by several vines woven together, and this so-called "flower" was supposed to be called a "propeller" in the previous life.

"Hey, Tiannan, what is this, it feels familiar?" At this moment, Xiaoxiao walked over, looked up and down at Tian Tiannan's new engine, and wondered.

"Haha, it's the crystallization of wisdom, come, let me show you." With a smug face, he took out a bronze bucket from his backpack and poured 100 points of liquefied sacrificial power into the bird's nest altar above the engine with a smug face.

With a slight wave of the green sheep cane, the golden light shone, and peaceful energy fluctuations slowly emanated from the engine.

"Woohoo..."

Immediately afterwards, the propeller began to rotate slowly, and under Tian Tiannan's deliberate control, it turned faster and faster, and the wind formed in the end was able to push Xiaoxiao several meters away.

"Imagine if it were installed on our ship..." Stopping the engine, Tian Tiannan said to the three girls with a smug face.

“！！！” Although there has never been a ship in this world, it does not hinder the cognition of the three girls, so after listening to Tian Tiannan's words, the image of a ship equipped with this strange altar that can sail quickly in the water without oars immediately appeared in their minds.

"Tiannan, tell me how it turns!" Without saying a word, he stepped forward and hugged Tian Tiannan's arm, and said coquettishly with a little coquettish eye, and on the side, the other two girls also looked at Brother Tiannan with an expectant expression, which greatly satisfied his vanity.

"Okay, we want to see what it's like inside!" It was difficult to resist the enthusiasm, so Tian Tiannan waved the Qingyang cane in his hand, and the vines on the engine shell immediately dispersed on their own, revealing the internal structure.

"You should know what happens when you tighten a strand of hemp rope to death and then release your hand, right?" At the same time, Brother Tiannan also began to explain.

"Miao Miao knows, she will disperse immediately!"

"That's right! Then let me ask Miao Miao again, what if you hold one end of the hemp rope and only release the other end? Affectionately stroking Miao Miao's little head, Tian Tiannan asked again with a smile.

"Do you still need to ask, naturally it is scattered to the side that is loosened! Hmmm..." As soon as the words fell, Xiaoxiao was stunned.

At the same time, the other two girls also understood, and hurriedly focused their eyes on the engine that exposed the internal structure, only to see that it was full of finger-thick vines the thickness of their forearms.

"Because the wind they produce when they are activated, I can't show you it when it's open, but it's just as the little baby said."

"These vines are all knotted together in the same direction, 24 strands at a time, and then they will wither and dissipate immediately after dispersing, and each strand used up, then the engine will draw the sacrificial power from the bird's nest altar above, and form a new one to replace the dissipated one, so that the number of 24 strands will always be maintained in the engine."

"As for why we have to keep 24 strands, it is to take into account the problem of speed, these 24 strands are small and connected to the big one on the propeller, and at ordinary speed can be released by two strands, if you want to accelerate, you have to release more strands at one time, but it should be noted that in order to avoid the simultaneous release of a larger number of vines and interfere with each other, the number of more than 6 strands is released together, and the engine has to extract more sacrificial power to form a layer of diaphragm on the surface of these vines, so as to shield off the influence between each other, This not only consumes a lot of energy, but also causes a lot of damage to the engine itself, so unless it is an emergency, it is best not to be too excited. ”

"Brother, Miao Miao doesn't understand something, it doesn't matter if one is one by one, so many are released at the same time, how to transfer the power to that together... Well, what about the propeller up? With a curious look, Miao Miao asked.

"It's a matter of power transformation, come on, see what's here!" As he spoke, Tian Tiannan showed the place where the propeller and the engine core were connected to the third girl.

At this time, the three girls found that 24 vines were connected to a large iron plate, with 24 round holes inside and outside a total of three layers, neatly arranged, and between the vines of the big iron plate and the propeller, there were many small iron disks.

"They are called gears, and there are a lot of bumps on the surface that allow them to be combined with each other, so the vines that are used as power are not directly attached to the propellers!" At this time, Tian Tiannan's voice came into the ears of the three women, explaining to them the crystallization of wisdom from another world in front of them.

"It's amazing... Transmission··· Tiannan, I feel like this thing is quite useful! Putting his arms around Tian Tiannan, Xiaoxiao was full of interest in such a novelty.

"Yes, they can make up a world..." Suddenly a little melancholy, Brother Tiannan looked up at the sky, not at a 45° angle, and there were no tears.

(About this magical engine, it's purely a personal brain, a serious nonsense, and its rationality please don't delve into it, of course, there are not many people who can see it here, I like you very much!) ）
