Zhen Qian finally comforted the crying Qingyan, and finally figured out what was going on, it turned out that Qingyan had been sealed with acupuncture when he was in the Qinglou, and he was afraid that he would not be able to have any more children of his own in this life.

Qingyan wanted a child of his own, and when he was with Genji, he didn't hesitate to agree for Zhen Qian when he heard Genji talk about the matter, if the first child was a boy, he would give it to Genji to raise him to become the head of the Shao Er family, so that Zhen Qian could also be wooed, if it was a girl, he would recognize Qingyan as his biological mother, which was a condition of exchange between the two parties.

Ordinary Japanese women will find a random Tang Dynasty to do the species, but it is a little troublesome for a Japanese nobleman like Shao Er Dongshang, first of all, the status of the man must be high, and secondly, the appearance must be outstanding, and afterwards, the woman and the child will leave, so this matter must be made clear in advance.

Aoi Ji has a round baby face, a figure of only a little more than one meter four, a full little Lori, which is already an outstanding woman in the Shaoer family.

The figure of the Japanese people in this era is generally not high, Fujiwara Shuxiong's figure of less than 1.6 meters is tall and powerful in the Japanese country, and the height of Shaoer Dongshang is only more than 1.5 meters, standing in front of Zhen Qian, he is about the same as a big boy who has not grown up, and when he sees the nobles of the Japanese country, Zhen Qian also knows why the Japanese country wants to be planted.

As long as they are women who have spent their lives, they will not only not be discriminated against after returning to China, but will be taken care of. After the child is born, it is carefully cared for, afraid of any mistakes, the child grows up, and also receives the best education, and chooses the best partner for them, so as to ensure that the offspring are better.

This kind of thing happened to him, Zhen Qian didn't know what to say, Qingyan thought that this kind of thing was an insult to Zhen Qian, there is no shortage of women around Zhen Qian today, and the child born naturally will not belong to Qingyan, which makes Qingyan have the care to let Zhen Qiandu plant.

Zhen Qian sighed, from the bottom of his heart, he agreed very much with the matter of the degree, which is completely different from the meaning of ****, if his son can become the next head of the family in the noble family of the Japanese country, it is a fool not to agree with such a good thing?

Since Qingyan has no opinion, Zhen Qian didn't pretend to be pretentious, Kwai Ji has good facial features, and if she is a little shorter, she will be raised as a little Lori!

The place where Zhen Qian is going today is actually on the Wufeng Islands, which is the third big island in the Wufeng Islands, and the first and second big islands are located at the north and south ends of the Wufeng Islands.

Shipyard is of course the most important industry of Zhen Qian, the selection of suitable shipbuilding conditions are very harsh, first of all, the wind and waves in the surrounding sea area can not be too big, secondly, there must be sufficient fresh water resources on the island, because there will be a lot of people who build ships, and then there is a need for a large piece of flat land, and finally the traffic must be convenient and smooth, and there must be water areas suitable for sea trials around, and there can be no reefs and these dangers.

Zhen Jiu has already selected the island for shipbuilding, but unfortunately there has been a shortage of manpower, and even the wood for shipbuilding has not been stockpiled until now.

The pirate captives brought back from the Osumi Islands temporarily alleviated the labor problem, and the construction of a shipbuilding dock on the island has now begun.

The Bohai Sea is not suitable for large-scale construction of ships, not because of fear of being discovered, but mainly because there are no large islands as a construction base. The Long Island off the coast of Penglai is the military port of the Dengzhou Naval Division, so it is naturally impossible to touch it, as for the Changshan Islands to the east of the Anton Governor's Mansion, there are many pirates there, and it is not a very good place to build ships for the time being, so Zhen Jiu bribed the Dengzhou Naval Division to buy warships.

In this year, in addition to robbing at sea, Zhen Jiu's biggest thing is to find good shipbuilders, shipbuilding is an ancient industry even in later generations, and it is no exception in dynasties like the Tang Dynasty, it is not easy to find an excellent shipbuilder.

For a good shipbuilder Zhen Jiu has always been respectful, a good ship for Zhen Jiu is completely different from a war horse for a knight, they all say that a good horse is hard to find, but a good ship is even more hard to find, sailing on the vast sea, no good ship is simply joking with his own life and death.

The north is not good at sailing, so there are not many shipbuilders, this refers to those good craftsmen who can make big ships, even if Zhen Jiu is willing to pay a lot of money to hire shipbuilders, no one is willing to live on a desert island with Zhen Jiu, so Zhen Jiu's method is very simple, directly sneaking into those craftsmen's houses in the middle of the night, and even taking them away with their families, it is impossible not to be a thief when they get to the island.

That's how those shipbuilders under Zhen Jiu came, and after Zhen Qian heard about it, he just smiled bitterly and didn't say anything.

In order to make a good ship to sail on the sea, before the advent of steel ironclads and engines, there were four technologies that were very important, watertight compartments, centerline rudders, keels and splicing technology.

The watertight compartment appeared very early, the Tang Dynasty has appeared, but the watertight compartment is being used on a large scale in the Song Dynasty, during the Jiaqing period of the Qing Dynasty, Cai Yongpu wrote the "Xishan Magazine Wang Yao Boat" contains: "In Tianbao, Wang Yao transported timber from Bo Ni to build a boat for Lin Luan. The length of the boat is eighteen zhang...... The silver-inlaid compartment has 15 compartments and can store as many as 30,000 to 40,000 quintals of goods", which is the earliest record of a watertight compartment. Later archaeology also proved that on the remains of ocean-going cargo ships in the early Song Dynasty, there was a very intact structure of watertight compartments.

The ship's internal compartments are tightly separated from each other, so that during navigation, especially in ocean voyages, even if one or two compartments break and enter the water, the water will not flow to the other compartments. From the overall point of view of the ship, it still maintains considerable buoyancy and does not sink. If there is too much water, the ship will not be able to support it, as long as the cargo is abandoned and the load is reduced, it will not sink to the bottom of the sea quickly. If the damage to the ship is not serious and there is not much water ingress, as long as the goods in the water inlet area are removed, the damaged places can be repaired without affecting the ship's continued navigation. If the water ingress is severe, it can also be repaired by sailing to the nearest port or land. Therefore, the watertight compartment not only improves the anti-sinking performance of the ship, but also increases the safety performance of long-distance navigation.

The centerline rudder makes it easier and faster to steer, and the centerline rudder with the new sail can flexibly change direction to keep the boat at a favorable sail angle for the wind. Without an efficient vertical centerline rudder, then the ship has no long-range sailing capability. For example, in the past, when maritime merchants sailed to the Wa Kingdom in spring, they could not return until the autumn monsoon rose, and they could only return by the monsoon after more than half a year.

Now, with the new sails and centerline rudders, ships can sail from all sides, downwind and crosswinds.
