In fact, there are natural conditions for the promotion of sauerkraut fish in the North Sea - the North Sea fishery produces a large number of herring, cod, mackerel, flounder, etc., as well as lobsters and oysters every year.

Although there is no black fish that is best suited for sauerkraut fish, herring and cod are available in large quantities. Moreover, sauerkraut fish does not have to use black fish.

Because of the large amount, like herring, there are many people in Europe who eat it. However, this way of eating is a little scary. For example, the Dutch are very fond of eating herring raw, holding live fish and eating it with their heads up, which is very savage and fearful...... There is also the famous Swedish herring canned in later generations, which is called a stinky one, and the wind stinks......

Therefore, Marin's introduction of sauerkraut fish can be regarded as saving these barbarians. Later, people used the processing method of sauerkraut fish to process large quantities of herring and cod to make canned sauerkraut fish. With better canned sauerkraut fish, naturally no one wants to eat the dreaded canned stinky herring anymore.

Later, canned sauerkraut fish became an important military material for the Beihai army, and a large number of them were produced every year to supply the army's needs. Because, whether it is herring, cod, or sauerkraut, it is super cheap. If the amount is large, you can save a lot of military spending. Moreover, it tastes good......

Due to Marin's vigorous promotion of trawls with winches and the adoption of modern VD trawls that are far superior to the current truss trawls, the fishing efficiency of the North Sea is higher than that of other countries, and the catch is very large. But most of the fish were made into salted fish. Because, fresh fish is difficult to preserve.

But the taste of salted fish is really not good, so add fresh herring and cod to white wine, ginger, chili pepper and other condiments to remove the fishy flavor, and cook it with sauerkraut to get a very delicious sauerkraut fish. When encapsulated with canning technology, it becomes a delicious and shelf-stable delicacy.

Canned sauerkraut fish made from this fresh fish is much better than the smelly dried salted fish. Moreover, its cost is not expensive. Although liquor and ginger are not cheap, they can already be mass-produced on the territory of Marin, and the cost is not high. As for the sauerkraut and fish themselves, they don't cost much. Therefore, canned sauerkraut fish is not only suitable for military supplies, but also suitable for selling to ordinary people, and it is very popular and has a long shelf life.

In addition to promoting turnips and Chinese cabbage, Marin also asked fishermen near Wilhelmshaven to try their hand at growing kelp. Several Japanese fishermen he brought back had already been sent to a fishing village near Wilhelmshaven to instruct the locals in cultivating kelp using the means of raft positioning.

However, there is a big problem with this method of cultivation - the raft is easily gnawed by maggots......

Therefore, Marin asked Kohler to arrange for some white iron sheets to wrap around the bottom of the raft, so that the raft would not be eaten by maggots before the kelp had grown......

……

In addition to radish, Chinese cabbage, kelp, etc., Marin also brought a variety of vegetable seeds from China. For example, the seeds of various vegetables such as winter melons, small greens, cucumbers, and shiitake mushrooms are secretly taken to hidden estates for cultivation. Because Marin has not yet appeared, these vegetables and other things need to be kept secret for the time being......

……

While Marin was quietly engaged in vegetable cultivation in his homeland, the distant Strait of Malacca also underwent earth-shattering changes - the Portuguese captured the city of Malacca......

Two years ago, before setting off for Daming, in order to sign an agreement with Portugal to divide the territory and clarify the ownership of Dongfan Island, Marin specially offered a plan to the Portuguese - to capture the Kuala Lumpur tin mine and lure the Malacca army out of the city for a decisive battle......

After receiving Marin's plan, Manuel I was not ambiguous, and immediately reorganized the fleet and army, sending a total of 24 warships and 5,000 infantry to the expedition to Malacca.

Of course, the Portuguese did not know that the fleet led by Columbus the Younger, after docking in India, specially bribed a group of Indian merchants and asked them to report to the Kingdom of Malacca, and suggested that the Kingdom of Malacca transfer its wealth to the inland areas.

However, the new Sultan of Malacca, Ahmed (Mahmoud's son), did not take this advice and blasted out the Indian businessmen who had gone to give advice.

Soon after, the Portuguese fleet finally came to the vicinity......

But instead of attacking immediately, the Portuguese fleet bribed several Malay fishermen to reconnoiter near Kuala Lumpur. After confirming that Kuala Lumpur indeed possessed a large tin mine, the fleet commander Albuquerque ordered the fleet to land near the island of Klang off the coast of Kuala Lumpur and repair there.

Subsequently, the Portuguese used Klang Island as a springboard to conquer what would become Port Klang, and then marched up the Klang River to Kuala Lumpur......

Because Kuala Lumpur is a Klang Valley region, the Portuguese didn't have much trouble finding Kuala Lumpur.

At this time, Kuala Lumpur, with the heavy investment of the Malacca royal family, had just opened up the Kuala Lumpur River Valley into a large mining area and smelting base, and hired a number of craftsmen from the Ming Dynasty to guide the local people in mining and tin smelting.

Unexpectedly, as soon as the tin mine was put into production, the Portuguese invading army came......

Then, 5,000 Portuguese infantry easily defeated the 2,000 Malacca troops guarding the tin mines, who did not have time to build a city, and took control of several thousand miners and artisans on the mines......

After taking control of the Kuala Lumpur tin mines, Albuquerque suspended mining, organized thousands of miners, and began to build the castle. Kuala Lumpur is a valley with steep terrain, and the tin mining in the past happened to mine a lot of stones.

As a result, thousands of Kuala Lumpur tin miners, under the persecution of the Portuguese, built a Kuala Lumpur Fort using the ore scraps from tin mining.

After the Kuala Lumpur Fort was completed, the Portuguese asked the miners to re-mine and smelt the Kuala Lumpur tin ore......

It was only by this time that reinforcements from the Kingdom of Malacca were belated......

The new Sultan Ahmed of Malacca was shocked and furious when he learned that the Kuala Lumpur tin mine had been occupied. So, he sent an army of 20,000 on an expedition to Kuala Lumpur.

However, because the newly enthroned he did not fully control the army, it took a long time to gather an army of 20,000 to attack Kuala Lumpur.

Then, when the 20,000 Malacca army, which had low combat effectiveness, arrived in Kuala Lumpur, the Portuguese stone castle had already been built......

At first, the Portuguese were also frightened by the 20,000 troops of the Kingdom of Malacca. After all, the Portuguese suffered a big loss in Malacca last time.

Therefore, the Portuguese somewhat overestimated the combat effectiveness of the army of the Kingdom of Malacca and chose to retreat in the castle for defense.

But later, as the Malacca army stormed the newly built Kuala Lumpur Citadel several times, the Portuguese found that the Malacca army was large in numbers and fierce in attack, but after the Malacca army attacked the city wall, it was easily defeated by the Portuguese army......

So, Albuquerque, who had regained his self-confidence, took advantage of the lunch opportunity of the Malacca army to lead 5,000 Portuguese infantry to suddenly pour out of the city and attack the camp of the Malacca army...... And when the Portuguese army approached the gate of the Malacca army barracks, the Malacca soldiers guarding the camp gate actually went to lunch and forgot to close the camp gate......

Then, the Malacca army, which was taken by surprise, was thrown into disarray and was easily routed by the Portuguese, with only more than 3,000 men fleeing in disarray......
