The Zheng family collects protection fees at sea, and their annual income reaches 10 million taels, and they are indeed wealthy, and it is not an exaggeration to say that they are rich and rival countries.

Therefore, with a wave of his hand, Zheng Zhilong asked Zheng Zhibao to bring 500,000 pieces of silver, two Dafu ships and four three-masted galleons to Tianjin to explore the reality of the Tiance Army and the purchase of goods.

Of course, the Zheng family's ships are armed, and each Daifuku ship is equipped with sixteen six-pounder guns and three eighteen-pounder guns, and this kind of warship is currently the most powerful firepower in Zheng Zhilong's hands. Even that kind of three-masted galleon had eight guns.

Since defeating the Dutch, Zheng Zhilong, who has abundant financial resources, is building Galen ships near the port of Xiamen. At the same time, two medium-sized Galen ships were under construction, with a displacement of about 800 tons, two gun decks, and twenty eighteen-pounder guns arranged on each side, which can be described as powerful firepower.

The ships that run the sea trade in this space are all armed, and at least one cannon must be arranged. The Tianjin Port Department is mentally prepared for this, and all seagoing ships entering the port must be inspected by the marines of the Tiance Army, and then the artillery must be disposed of to prevent all possible hidden dangers. That is, the artillery fuses and gunpowder will be confiscated and returned to the ship's owner when leaving the port. Not only artillery, but also muskets and blades were temporarily confiscated.

It's just that the ships of the Zheng family are more exaggerated, and they entered the port under the supervision of the maritime surveillance warship. Zheng Zhibao's purpose this time was to trade and explore the truth, but since he was exploring the truth and the truth, he did not reveal his identity.

The goods that the Zheng family was preparing to purchase were mainly cloth, which was the main commodity that Wang Yue promoted in Hirado. didn't think of Tianjin, Zheng Zhibao knew that there were so many good things in the starting point city.

So Zheng Zhibao quickly turned into a Shanxi coal boss, and everything he saw was one word: "buy"!

Cloth of all colors, buy 10,000 pieces! Tianjin Port is full of glass windows, and 3,000 boxes of glass come in. Mirrors of various sizes, buy 3,000 faces! The Zheng family has immigrated 70,000 or 80,000 people to the island of Taiwan to reclaim fields, all kinds of farm tools, and buy 30,000 pieces! Sewing needles, buy 50,000 pieces! Enamel washbasin enamel jar, buy two thousand pieces!

There are many mosquitoes in the south, wind oil essence, cool oil, buy! Kerosene lamps, kerosene lighters, good things, buy! Good sewing machine, buy! Kettle, buy!

Zheng Zhibao lives in a guest house specially built for foreign merchants in Tianjin Port, and has experienced the convenience of running water, flush toilets and other things. It's a pity that these things are not sold, because if you want to get tap water, you must use a centrifugal pump to beat the water to a high place, and if you want to use a centrifugal pump, you need to use a generator, and things that are too troublesome are not sold.

The guest house has electric lights, which are also not sold. In retreat, Zheng Zhibao still bought a few sets of sofas and glass coffee tables, which are not bad.

Anyway, it's just buying, buying, buying, there are too many good things, and the Zheng family is not short of money, so they buy it for several days.

Zheng Zhibao is still a little unsatisfied, and he even wants to buy the floor tiles in the guest house, but unfortunately they don't sell them. Cement is also a good thing, and I heard that it can be sold to the outside world by the end of the year.

In fact, what he wants to buy most is the weapons and warships of the Tiance Army, in Tianjin Port for so many days, the warships of the Tiance Army Navy have been attracting his attention all the time, and the reason why he has been in Tianjin for so long is to observe the warships of the Tiance Army Navy is also the main reason.

Zheng Zhibao instructed his subordinates to pack the goods purchased today on the ship, these days the crane of the civil wharf in the Tianjin port area is mainly for him, a big businessman, and the Tianjin Trade Branch also welcomes a big businessman like him, so the service is particularly enthusiastic.

"Sen'er, do you think Wang Sihua will sell us a warship like that?" Zheng Zhibao did not answer Zheng Sen's words, but greedily stared at the Tiance Navy warships in the distance, especially the product tanker, which was simply a giant on the sea.

When he came to Tianjin, Zheng Zhibao opened his eyes, and all kinds of new things came to him. Living, using, buying, and the vehicles running around on the construction site not far away, it is really dazzling.

But the biggest impact is the huge number of warships in the Tiance Navy.

With the arrogance of their Zheng family across the South China Sea, if someone wanted to go on board the ship to inspect or even disarm themselves, maybe Zheng Zhibao would have turned his face a long time ago.

But seeing the huge product tanker, as well as the dock landing ship and supply ship that are not small, Zheng Zhibao is really a little weak-hearted. Nima, this battleship is more than a hundred times larger than his Daifuku ship, how can this be played? Even the maritime surveillance warship that came to warn them was four or five times larger than the Daifuku ship.

In fact, he didn't know that the 115,000-ton product tanker was just a queen of the sea, and it was just scary to look at.

I don't know how many times Zheng Zhibao has asked this question these days, it's a bit like a dream, nagging.

However, Zheng Sen can also understand that as a family on the sea, how can he not salivate when he sees such a battleship?

Zheng Sen repeated the answer: "Let's visit that Wang Sihua, don't we know?" Since their shipyard is building ships, maybe they will actually sell it. ”

The starting point city does have its own shipyard in the port of Tianjin, and it does not allow idlers to approach. Tianjin is not a shipyard here, but two shipyards and four docks. However, it is not that Zheng Sen is building the kind of warship of the current Tiance Navy, as Zheng Sen thinks, but is building a wooden cargo ship.

To develop maritime transport, it is necessary to have cargo ships. Wang Yue already planned to continue to send another batch of modern freighters from another plane.

However, building one's own ships or even warships is the only way, and building iron ships will not be gradually implemented until the Shijingshan Iron and Steel Plant is put into operation.

The current shipyard is a 1,200-ton wooden cargo ship built by a shipbuilder hired by the Ming Dynasty according to the drawings of coastal flat-bottomed cargo ships in the 50s provided by Wang Yue. This kind of cargo ship has a simple structure and a large space, so it can be used highly.

This kind of cargo ship was considered a small and medium-sized cargo ship in the fifties of the previous life, and it was also a large cargo ship in the Ming Dynasty of this time and space, after all, this ship was twice as big as the Fu ship.

The keel of the boat is made of wrought iron, and the power of the boat is high-power marine thrusters, two per ship. The use of thrusters, rather than sail hybrids, allows for a significant reduction in the number of crew members.

Although the sailboat can travel farther without diesel power, Wang Yue still uses pure diesel power, just to reduce the difficulty of personnel training, and now he is most lacking seafarers.

The materials for shipbuilding were logs brought from North Korea, mainly camphor and elm, which were then dried in dryers.

Shipyards use a lot of modern woodworking machinery such as chainsaws, so shipbuilding is fast.

A group of shipbuilders can be trained through wooden shipbuilding, and welding is widely used in the construction of Shijingshan Industrial Zone, and the welder team has become increasingly large. In the future, if you want to get on the iron ship, you will also need a large number of welders, and when you go to Shijingshan Iron and Steel Plant to put it into production, the construction of the iron ship will almost be completed.
