In the "Dawn" lookout pavilion, Ge Bi went out to look at the sky, spat on his index finger to test the direction of the wind, leaned out and shouted, "Raise the anchor, raise the main sail!" ”

After a pause, he took a deep breath and shouted, "Rise...... Left and right winged sails! ”

He saw that the ratchet at the top of the newly erected two-foot mast slowly turned, and as the thumb-thick rope slowly pulled, the triangular wing attached to it was sewn together with three layers of cotton cloth and unfolded little by little; The men tugged at the ropes with all their might, and the spin-cornered sails creaked outboard and immediately puffed up in the hunting breeze.

The triangular wing sail is two feet high, one foot and five feet long, and it is nothing compared to the main sail, Childe said, this is just a "test product", and what is the "strength" of the hull is not enough, Childe told Ge Bi to think about how to use the lower wing sail in different wind directions and different directions - there are so many new words for Childe, but after a little explanation, Ge Bi can understand what it means.

There is no need to think about it, Ge Bi, who has run old in the sea, can already feel the power brought by the winged sail, and the sand boat is obviously faster.

Now Ge Bi is very fond of his son - originally he was proud of himself as a good sailor, although he also respected his son, but more because his son was a talent and his character was good; As for sailing on the sea, it depends on his Ge Bi's ability.

Who would have thought that Gongzi would come up with such a ghostly idea for navigation, when Gongzi told him this idea before, Ge Bi also suspected that he was a little whimsical, and when Gongzi took Ming Ye to erect the winged sail in less than three days, Ge Bi was really convinced - there are such gods in the world, obviously they don't know much about navigation and ships, but just think of an idea can make an old shipwright like Ming Ye amazed, I really don't accept it!

Seeing that the "Dawn" was getting faster and faster, Ge Bi remembered to wave to the beach behind him, and Ming Ye and seven or eight boatwrights had already turned into a small group of black spots.

His mood was agitated, but he didn't know that at this moment, Ming Ye's heart on the shore was even more agitated and full of expectations.

In order to add winged sails to the "Dawn", the old shipwright was really busy in the past two days - he had to do everything himself, such as material preparation, processing, testing, and installation.

Like Ge Bi, the old shipwright also underwent a change of thinking from believing in doubt to being convinced.

The old shipwright knew much better than Ge Bi Ke how much the spin sail could speed up the boat, so the great sense of accomplishment that the first wing sail could be made from his own hands made the old shipwright's heart heavy.

What surprised the old shipwright even more was that although the son of the Chu family said that he didn't know anything about shipbuilding and repairing ships, he knew that without changing the hull structure, the wing sail could not be built too big, otherwise it would tear the boat gang, which made the old shipwright impressed - he had built a ship for decades and knew that this was normal, and the young man of the Chu family also understood that this truth was very rebellious.

Ming Ye is now looking forward to the return of the son of the Chu family, and the son can say that there is enough time after he comes back, and he will completely renovate this "Dawn", through the method of reinforcing the beam, so that the longitudinal mast of the wing sail and the keel can be connected, so that a larger wing sail with a height of three zhang and a length of five zhang can be added, and the speed of the "Dawn" at that time can be at least half higher than the original!

What makes Ming Ye look forward to it even more is that Childe is also going to install a streamlined bow for the "Dawn", as well as installing hydrofoils below the waterlines on both sides, Childe said that with these two things, the ship will be faster and more resistant to sinking. Although Ming Ye has never heard of these two things, but after seeing the successful installation and use of the winged sail, Ming Ye is extremely looking forward to these two things, and I wish that Gongzi would stay for more than ten days, so that he can see what a bow and hydrofoil are.

After two days of getting along, he already completely believed in that young little Xiucai, there was nothing he couldn't do!

Just when Ming Ye was fascinated, the "Dawn" had turned into a small black spot, and the little Xiucai who made him full of expectations was sitting in the stern of the boat without any image at the moment, leisurely throwing out a long fishing rod.

Next to him, Chen Shangren and Liu Zhongwen sat on the left and right, also half-lying and half-leaning on the roof of the anchor ingot cabin without any image.

"Little Fu'er, I'm weird, you know the drill soldiers, you know the improved bird guns, you still know how to make the wind steer the ship at sea, is there anything else in this world that you don't understand?" Liu Zhongwen put his hands behind his head, looked at the blue sky and asked faintly.

"Of course there is, for example, I don't understand how to practice one breath inside, that's your strength." Chu Fan smiled and responded casually.

"I didn't mean this," Liu Zhongwen propped himself up, stared at Chu Fan and asked, "It's strange to me where did you know such things?" ”

"Yixian, I'm also curious," Before Chu Fan could answer, Chen Shangren next to him also spoke, "As far as the old man knows, that Xu Shilang has a very high vision, and the idle scholar can't enter his magic eye at all, why does he favor you alone?" ”

Chu Fan rubbed his nose and muttered, "Shibo, it's not that my family teacher favors me, it's my senior brother who accepted the apprentice on his behalf." ”

Chen Shangren shook his head, ignoring Chu Fan's tricks at all, "It's all the same, Sun Yuanhua Sun is Xu Shilang's proud apprentice, if you don't have something surprising, where will people look at you squarely?" ”

Chu Fan saw that he couldn't move, so he had to come up with the rhetoric he had already thought of, "Actually, I understand this, I read it in books." ”

"Oh?" Liu Zhongwen asked curiously, "What book?" ”

""Taixi Zhujia Tongdian"" Chu Fan made a nonsense title.

The two people around him picked their heads and thought about it for a long time, but they couldn't think of such a book at all.

Chu Fan's hand sank, and he hurriedly picked it hard, and a huge sea fish flew to the lookout pavilion on his head, and after a while, Doudou stuck out his head and reported, "Childe, it's a big yellow croaker." ”

Chu Fan smiled and asked him to re-hang the bait, and after throwing the fishing rod far away again, he looked at the two people who were full of doubts, "Zhongwen may not know, but Shibo should have heard that there is a doctrine called Lanxue in the Wa Kingdom." ”

Chen Shangren nodded and said, "This old man has heard of it, and it is a school of Japanese people who specialize in the Taixi doctrine. ”

Chu Fan said with a smile, "This "Taixi Family Dictionary" is the culmination of the Japanese people's study of Taixi's doctrine, including arithmetic geometry, clever equipment, the art of war, battle arrays, and even navigation and shipping. Before my father's accident, I bought this book in the country of Wa and brought it to me, and I read it for more than a year before I got to the bottom of it. ”

Hearing his explanation, Chen and Liu suddenly realized and sighed again and again.

Chu Fan secretly wiped a handful of sweat, so that he could hang it well, and finally passed it perfunctorily.

I didn't think that Chen Shangren's next sentence made his heart rise again.
