In the Tianjin shipyard, everyone gradually dispersed, only Li Dongyang, Zhou Jing, Zhang Mao and others were still thinking about what Liu Jin had just said.

One whale is equivalent to beef for hundreds of cows, lard for thousands of fat pigs... Liu Jin's words are still echoing in the minds of Li Dongyang, Zhou Jing, and Zhang Mao.

"Li Gong~"

Here, Liu Jin came to Li Dongyang and the three with a smile on his face, and greeted Li Dongyang with a smile, as for Zhou Jing and Zhang Mao, although they didn't know each other, they also bowed their hands and saluted, which was regarded as a greeting.

"Liu Jin, this whale is really as you say, one whale can be equivalent to hundreds of cows and thousands of fat pigs?"

Li Dongyang came back to his senses, looked at Liu Jin with fiery eyes and asked.

"Whether what I said is true or not, I think it will be revealed soon, and when this whaling ship is built, we can go to the sea to hunt whales, and then I will order someone to send a whale back to the capital, and Li Gong can go to see it in person."

Liu Jin smiled and said confidently.

"Well, then I'll see."

Li Dongyang nodded with satisfaction, and then pointed to Zhou Jing and Zhang Mao next to him and said, "This is Zhou Jing Zhou Gong, the head of the household, and this is Zhang Mao Zhang Gong, the British Gong." ”

"I've seen Zhou Gong and Zhang Gong."

Liu Jin once again respectfully saluted Zhou Jing and Zhang Mao.

"Hmm~ It's better to see than to hear, and it really deserves its reputation."

Zhou Jing pinched his mustache, his eyes were full of appreciation for Liu Jin, along the way, he saw the starvation all over the land, and saw the unique miserable scene of the famine years, but when he arrived in Tianjin, he saw another scene.

Everything here in Tianjin is undoubtedly inseparable from the young man in front of him, if there is no Liu Jin, I don't know how many victims will starve to death, where is like now, the victims eat meat to survive.

There is also Liu Jin invented cement, the artifact of the country, once this cement is promoted in all aspects, the Ming Dynasty will undergo earth-shaking changes, and the significance is too great.

"Nice, nice~"

Zhang Mao also nodded with a smile and Liu Jin said, which made Liu Jin confused, I don't know what he meant by what he said was good, whether he was a good person, or something else.

"Gong Li, Gong Zhou, Gong Zhang, let's sit down and talk slowly."

Liu Jin looked at the environment of the shipyard, it was obvious that this was not a place to entertain guests, and after thinking about it, he also proposed to find a place to drink tea and chat again.

"No need, we are very curious about the changes here in Tianjin, how about we walk and talk here in Tianjin?"

Li Dongyang smiled and shook his head, then thought about it and proposed.

"Everything is arranged by Li Gong."

Liu Jin nodded and replied, and then everyone also began to chat while walking in the shipyard.

Li Dongyang, Zhou Jing, and Zhang Mao were very curious about everything here, so they didn't rush to talk about business, but talked about everything here first.

Zhou Jing looked at the shipyard in front of him, this shipyard is very large, with a large number of shipbuilding docks, and at this time, there are ships under construction in each shipbuilding dock.

These boats are large and small, the small boats are just the size of ordinary river boats, the large ships are smaller than the lucky boats, some are almost finished, and some are only laid with a keel.

At a glance, some boats know that they are the traditional fortune boats, yellow boats, fast boats, Jianghan class boats, eight-oar boats, etc., and some boats look very special, and the shape and structure of the ships on the Ming side are quite different.

"Liu Jin, the shapes of these ships are very peculiar, what kind of ships are these?"

Zhou Jing asked, pointing to a few ships.

"This is a fishing boat specially developed by our Tianjin shipyard for fishing, its tail is different from ordinary boats, and the design of the opening is adopted, which is to facilitate the fishing of the caught sea fish into the fish tank."

"A fishing boat like this, it goes to sea once, and it only takes one day to catch more than 100,000 catties of sea fish."

Liu Jin explained to the three of them very proudly.

"What is trawling?"

When Zhou Jing heard this, he hurriedly asked.

"Trawling is a fishing method in which a large net is cast into the sea and then dragged by a boat, simply put, it is a fishing net that is dragged into the sea by a boat."

"This trawling is the best way to catch fish in the ocean, and as long as the fish enters the net, it will never come out."

Liu Jin kept gesturing with his hand and explained the principle of trawling.

"I see~ How much does your fishing boat cost? Will it be sold? ”

Zhang Mao looked enlightened, then thought about it and asked, to be honest, he was moved, this sea can catch more than 100,000 catties of sea fish a day, this sea fish can be sold for two or three wen a catty, this trip to the sea is more than 300,000 wen, converted into silver is almost two thousand taels.

Aside from all kinds of costs, there is no problem at all in earning 1,000 taels of silver in half a day on this trip to the sea, and in a year, this fishing boat can earn more than 300,000 taels of silver, and there are several such fishing boats, which can also earn millions of taels of silver a year.

It's not that I don't know, I'm shocked, it's a project that makes millions of dollars a year, and he Zhang Mao is naturally very excited, so he will ask for the price.

"The cost of this fishing boat is quite expensive, the wood it uses is not ordinary wood, it needs to use the big trees of the previous year, this ship is just in terms of materials, it needs more than two thousand taels of silver, plus the labor here in the shipyard, etc., if this one is sold to the outside world, it will need at least 20,000 taels."

Liu Jin looked at Zhang Mao, rolled his eyes, and quoted a sky-high price of 20,000 taels per ship.

Of course, Liu Jin didn't tell the truth, this shipbuilding does need to use good wood, the best is naturally teak, but there is no teak in the northern region at all, and it can only be used locally, and it is basically fir wood, pine, cypress, elm, camphor wood, nanmu and other common trees.

Although the timber was carefully selected and used from the previous vintage, the purchasing power of silver in this era was very high, and the wood needed to build a fishing boat would not cost more than two hundred taels of silver.

The reason why Liu Jin shouted high is obviously for the sustainable development of the shipyard, the biggest expense of the shipyard is not to buy wood, but to train these shipbuilders and masters, their treatment is very good, not only high wages, but also many benefits, as well as houses and other distribution.

These are all things that need money, and the shipyard is not a charity, and there is no one to cover for it, so naturally it also needs to make a profit, and the ship also needs to be sold.

Since it is to be sold, it is natural to sell it at a high price, so that we can take the road of high-tech enterprises in the future, which have technical content and scientific and technological content at an extraordinary price.

Because it is necessary to sell at a high price to be able to feed these skilled workers and masters, recover the high R&D investment in the early stage, and accumulate funds for continuous upgrading and transformation in the later stage.

If this fishing boat is not sold for 20,000 taels, the shipyard will not make much money, and naturally there will be no way to continue to develop.

Although the price is high, Liu Jin believes that this fishing boat will definitely not worry about selling, and now the whole Tianjin is filled with the fishy smell of sea fish, and someone has already noticed all this, and asked the shipyard about the price of this fishing boat.

Since Zhang Mao in front of him can ask, he must also be moved, and Liu Jin is also waiting for someone with huge influence like Zhang Mao to take the bait.

Again, only when more people profit from the ocean can there be a more powerful force to promote the opening of the sea ban in the Ming Dynasty.

In the final analysis, it is actually a matter of interests, and since ancient times, everything has been a game between interest groups, and everything has never changed.
