Ganning established more than ten Jinfan docks along the coast of Huiji, and began the manufacture and research of ships, among which the two largest shipyards, one in Shanyin and the other in Zhang'an.

Zhang'an is directly adjacent to the sea, surrounded by a large number of giant trees, there are often more than ten people hugging in the jungle, and there are three or four meters of teak in the thinnest part of the main trunk - it is difficult to find such a thick teak in later generations, which are the best materials for making keels and decks.

The rest can be used to make some less important parts of the pine, fir wood, is inexhaustible.

It can be said that even when the Ming Dynasty went to the West in later generations, it did not have the current convenience in terms of natural resources......

And Shanyin is the governance of Huiji, not the Shanyin of Shanxi in the later generations, but in the Shaoxing area, near the Qiantang and Fuchun of Wu County, on the advantage of local materials, it is slightly worse than Zhang'an, but it is close to the Hangzhou Bay of the later generations, as a bay, the sea surface is relatively calm, which is equivalent to the entrance in a simple mode.

In addition, it is more convenient to enter the Qiantang River on the spot, or enter the Sanjiang River along the coastal sea, and then enter Zhenze.

That is to say, in terms of boat manufacturing, Zhang'an Jin Sail Dock focuses on sea ships, and Sanyin Jin Sail Dock focuses on river ships.

If you want to do a good job, you must first sharpen your tools - and what is more important than "tools" is naturally "Tao", that is, the principle of manufacturing!

When Ning Jin had not absorbed gold and did not have the foundation for large-scale shipbuilding, the shipwrights were not idle, but experimented with new sails under the guidance of the drawings that Bai Tu handed over to Gan Ning......

According to the drawings of the white map, a real "sailboat" can not only sail against the wind, but even cross the wind.

This is completely fantastical in the view of the shipwrights of the Eastern Han Dynasty, if it is not Gan Ning, who is the chief inspector and concurrently serves as the general of the warden ship, maybe they have protested, but it is Gan Ning...... But no one dares to talk nonsense.

It doesn't matter if you don't have money, make a model first - a small boat as big as one person can always be made!

And under the guidance of the drawings, a little bit of exploration, it was really a successful experiment, and now the "simulated boat" has been able to sail against the wind, although the simulated boat is a single sail, and the later generations as a competitive single sailing boat, but the principle is the same.

The boatwright's mastery of curved currents is still very shallow, and it is difficult to "go faster than the wind", but they have been able to adjust the angle of the sail and sail in a zigzag shape against the wind!

As for the primitive steamship, there are many blind spots in the construction that have touched the shipwright at this time, and other types of work need to work together, Gan Ning seems to be irritable, but he is not impatient, let them start to practice from improving the sailboat.

Most of the river boats are the technical improvements of the Soochow period, while the sea ships are based on the sand boat model, that is, the flat-bottomed ships that are not afraid of running aground, which are simpler than the pointed bottom of the Fu boats, and the sea ships do not need to consider the improvement of combat effectiveness for the time being, and only take navigation as the main direction of research and breakthrough.

……

At this time, in the general's mansion in Jinling, Bai Tu received the documents sent by Liu Biao, and he had to get rid of the high-sounding nonsense, in general...... Liu Biao rejected all of Bai Tu's requests.

Previously, after the drought expanded, Bai Tu was worried that the reserve of relief grain would be insufficient, so he started the idea of asking Jingzhou and Yizhou to buy it.

As for the Central Plains, Guanzhong? Forget it, those princes who have been beaten into a pot of porridge are short of food themselves, and it is not convenient to take the road.

"Liu Biao, this guy is simply a vain clan! Ask him to buy grain, he doesn't sell it and doesn't say anything, even if we want to buy grain from Yizhou, he doesn't want to borrow it! Bai Tu was quite indignant.

Lu Su didn't think it was strange......

Jingzhou, especially Nanjun and Nanyang, is sitting on Yunmengze, and the drought in Huainan has little impact on him.

But Liu Cheng was obviously wary of Bai Tu, how could he sell him grain?

As for asking Yizhou for grain and grass...... Lusu is not very optimistic, although it can take the Yangtze River waterway, which is much smaller than the 6 road to be transported by manpower and animal power, but there is a Jingzhou in the middle, and the cost is still a little high.

It is even slightly higher than the current grain price in Wu County, which has risen four or five times since the start of the drought, reaching a thousand dollars and one stone.

Bai Tu did not embarrass the household department too much, it is said that it is also the responsibility of the household department to regulate and control grain prices, but in the case of the prohibition of the sale of relief grain, it does not matter if the grain price is higher, after all, the people want to buy relief grain.

The trading volume of ordinary grain is very low, and basically only the wealthy families trade with each other, and the other is the general's mansion to buy.

In contrast, the Criminal Department's investigation and punishment for the resale of relief grain is much greater, and there are already two local tyrants, so their homes have been raided, which makes people understand that this is a red line that cannot be crossed.

After all, in order to facilitate preservation and reduce transportation consumption, the relief grain is stored in the county's own treasury, so ...... Where will the relief food that is sold on a large scale come from?

After Cheng Ji's processing, the relief grain is basically an anti-counterfeiting product, and the dignitaries who really want to save face do not dare to fight the idea of relief food now, otherwise it is equivalent to directly admitting to the people that they have moved the disaster relief treasury.

Lu Su had calculated that if he bought grain from Yizhou, all kinds of costs would be superimposed, and it would basically cost 1,500 yuan to harvest a stone of grain in Chaisang.

However, now Jiangdong's grain is basically priceless and marketable, and buying grain from Yizhou at a premium can also be considered.

It's just that there is no need to think about it now, Liu Biao, who occupies the middle section of the Yangtze River, has no intention of borrowing the road at all, and the grain from Yizhou in the upper reaches of the Yangtze River cannot fly directly to the lower reaches......

When the Gan clan of Shu County came to Jiangdong, the light boat and hundreds of people were not conspicuous, and Liu Biao did not need to agree, but it was too simple to block the boatload of grain!

As for piecemeal purchases, small boat deliveries?

The cost is several times higher, and Bai Tu can't afford it......

Because Bai Tu accepted Sun Ce, who had a grudge against Liu Biao and Huang Zu, compared to Cao Cao and Liu Bei, Liu Biao is the person who is most wary of Bai Tu now.

"Zijing, in addition to cleaning up the river and digging the canal during the dry season, in the south of Danyang and Wu County, we also started to dig deep wells to prevent accidents!" After Bai Tu was angry, he still began to arrange the project.

This year, because of the reduction in grain production, in line with the idea that using relief grain to "open warehouses for disaster relief" is a loss in vain, and "employing and relieving labor" will not pay compensation, Baitu has intensified the "employment and requisition."

While the stock of relief grain has been greatly reduced, the labor force in Wu County and Danyang is very abundant!

At the same time, Bai Tu also wanted to send a message to Poyang and Huiji, although the consumption on the road was larger, but he also tried to send some food to Wujun and Danyang......

Poyang County and Huiji County are far away from the Yangtze River, with the former having the Poyang River system and the latter south of the Qiantang River system.

The drought situation in Huainan has not greatly affected both Huiji and Poyang.

If this continues, Bai Tu is worried that the abundant relief grain originally estimated will be insufficient, so he already hopes that grain and grass can also be raised in Poyang County and Huiji County......

It's just that the degree of openness in Poyang was insufficient before, and the cultivated land area was somewhat small...... It is also known for its rugged mountainous terrain, and it is very difficult to transport grain.

Bai Tu also thought about it all night before he came up with a "good way" that could be all-purpose!
