In terms of the use and research of ships, Zhen Qian's actual experience is even inferior to Zhen Jiu, and he only occupies a thousand years of experience, if you put these aside, Zhen Qian can't insert a word, and he is Zhao Kuo and others in the Tang Dynasty.

Zhen Jiu wanted a battleship, but this wish could not be satisfied for the time being, but after knowing the existence of artillery, he also realized that the artillery could not be used on the current ship structure at all, and the kind of unreinforced ship plank was probably going to shake the whole ship apart after a few clicks.

In the original plan, Zhen Jiu and the Dengzhou Navy had secretly and privately finalized two long-lived Qianshi sea ships, which would install flywheels on the Bohai Islands, and then transport 1,000 Tang people to settle down in the Wufeng Islands, and Zhen Qian promised Zhen Jiu to install six one-pound guns on one of the ships as a preliminary experiment.

Zhen Jiu is getting harder and harder to deceive now, so he found a gap to leave Zhen Qian behind, and pulled Wang Tianxing to drink, saying that the brothers hadn't had a drink for a long time.

When Zhen Qian came back, he found that Ke Ming was pulling a few people to pile sand sculptures on the beach, the sand sculptures were very large, and they looked very beautiful, as if they were stacked according to the size of one to ten.

"Not bad! You can even think of this way! ”

Zhen Qian was taken aback when he saw the sand sculpture, he originally thought that Ke Ming would use wood to build a model of a ship, but he didn't expect to think of using sand as a material, his brain hole is not ordinary!

This method is so wonderful, Zhen Qian couldn't help but admire, he didn't even think about it at the beginning.

Ke Ming and a few people spent an hour piling up four sand sculptures of different ship types, each of which was lifelike, standing in front of the model could make a rough comparison very intuitively, and even people like Zhen Qian, who didn't know much about ships, could see some of the context.

"Who of you came up with this good idea, and should be rewarded?"

"You don't need to reward you again, just reward a few pieces of candy!" Yan Bo laughed and said: "When we came out to breathe, we saw a few children playing with sand people on the beach, Zhen Lang, how do you say we should be rewarded?" ”

Zhen Lang also laughed, the inspiration came from life, this is not false at all!

"They all deserve to be rewarded! Even the children of the sand builders should be rewarded! "At this time, the level of a manager can be best reflected, although the matter is very small, Ke Ming did not invite a few rewards, but he can't turn a blind eye, "Many ways to solve difficulties are a flash of inspiration, as long as you grasp it, the difficulty will not become a difficulty?" ”

Ke Ming sat next to the fire, looked at a few sand sculptures, picked up the wine jug and poured a sip of wine and said: "The appearance of the sea ship should indeed be slender, I have reached an agreement with Lao Yantou, and the center of gravity of the sea ship should continue to decline, so that the sea will be more and more stable....... ”

Of course Zhen Qian has no opinion, he can only understand the truth contained in it, he is actually helping the seedlings now, the bigger the step, the easier it is to fall on his heels, if it is just to build the sea ships of the Tang Dynasty, these people will not have much difficulty, but if the ships built don't even understand themselves, what if they don't make jokes?

"I'm not against it! Do more experiments, we now have the time and financial resources to do these things, a good ship is not a few pieces of wood put together, I still understand these truths! ”

Zhen Qian piled up a model of a windsurf board on the ground and said: "This thing is called a windsurfing board, and the windsurfing board is composed of a board body with a stabilizer board, a mast with a universal joint, a sail and a sail pole. Using the natural wind force blowing on the sail, stand on the board, manipulate the sail through the sail rod to make the valve plate generate speed and travel on the water, and turn on the water by changing the wind center of the sail and the center of gravity position of the board. This kind of windsurfing can usually be used as sailor's training, and in the future, every sailor will learn to fly such a windsurfer, and this kind of sport will gradually be promoted to every child on the island, and I want everyone here to like this kind of sport? ”

Zhen Qian wants to make people curious about the ocean through these sports, not only windsurfing, but also dinghy, surfing and other sports, and unconsciously fall in love with the ocean in entertainment.

"This thing can sail on the seas?"

"This is actually wood, wood can float on water, can also float people, with the help of the wind to drive, the windsurf board is a soft sail, no matter what direction the wind can be used, you make this thing first, experiment to know the benefits of soft sails?"

Everyone will be skeptical, and they will not dare to directly enter the eighteenth layer of hell for their proposal, if others proposed such a plan, they would have been ridiculed a long time ago. Zhen Qian also remembered when he suddenly saw the sand sculpture, in fact, there were many sports in later generations, skateboarding, surfing, diving, pedal boats, etc., all of which are good water sports, but they are not suitable for taking them out now.

There are a lot of prey on the Wufeng Islands, but it is estimated that it will suffer a catastrophe, and a rare animal that I don't know what kind of treasure is caught by the guards from the mountains and roasted on the fire, and the aroma is overflowing and makes people have an appetite when they smell it.

During this time, many people have begun to lose their appetite for seafood, smelling the smell of seafood and eating all kinds of seafood every day, and now their eyes are green when they see green food.

The next day, the carpenter spent more than an hour making a surfboard, and in the curious and puzzled eyes of countless people, Zhen Qian jumped into the sea with the surfboard.

The surfboard is carved from a single piece of cork, weighs more than 20 catties, is about 3 meters long, about 60 centimeters wide, the front and back ends are slightly narrower, and there is a stable tail fin at the lower back.

Surfing is wave-driven and takes place in windy and rough waters. There are also certain requirements for the height of the waves, and the wave height cannot be less than 30 cm. Surfing requires high skill and balance, and at the same time is good at swimming long distances in wind and waves.

Zhen Qian lies prone (or kneeling) on the surfboard and paddles with his hands to a place where there are suitable waves as a starting point. When the waves push the surfboard to slide, Zhen Qian keeps the surfboard in front of the wave crest and stands up, with the legs naturally open in front and back (usually the balance leg in front and the control leg in the back), the knees are slightly bent, and the waves are followed by the waves, and the slide is fast.

In later generations, many surfers were towed by jet skis to reach a predetermined sea area, and when they felt the waves pushing them forward, they let go of the tow rope and moved forward on their own. Now Zhen Qian doesn't have these conditions, and the waves around the Wufeng Islands are not suitable for surfing, so he can barely let Zhen Qian perform in front of people.
