After returning to the hotel, Yang Jing couldn't wait to enter the space.
The gold had long been placed in a corner of the space. In that corner, there was nothing but gold.
What Yang Jing was interested in were the four teak barrels.
Through the perspective skill, Yang Jing already knew that the four teak barrels were filled with whale oil, and in the whale oil was a well-sealed iron sea
The use of whale oil to preserve things has been around since the days of the Vikings. Before the advent of petroleum, whale oil was considered a universal oil. Especially in Western lighting, before the discovery of petroleum, whale oil and gas were the most commonly used.
However, gas is too expensive to produce and very inconvenient to transport, so many Western people use whale oil for lighting.
Especially in the early 19th century, the promotion and application of steam engines liberated manpower to a great extent. At the same time, scientific and industrial knowledge grew explosively, people's motivation and enthusiasm for learning grew simultaneously, and the demand for indoor lighting increased sharply. This caused the price of whale oil to rise sharply, and whaling became a lucrative livelihood.
At that time, many emerging industrial countries such as Britain, the Netherlands, France, Norway, etc. had participated in large-scale whaling activities.
When whaling is mentioned today, ten out of ten people will think of Japan. But who would have known that Japan's whaling industry is nothing compared to that of the United States two hundred years ago.
From the 1820s to the 1860s, the United States ranked first in the world in terms of whaling.
The forty years from 1820 to 1860 were the "golden age" of the American whaling industry. During that period, the development of the domestic economy and the rise of the Industrial Revolution in the United States drove a huge demand for whale oil. Smart humans also made more diverse use of whales, and whale products included soaps, skin care products, lubricants, women's corsets, etc., which can be said to be fully utilized.
At that time, the income from catching a whale was equivalent to half a year's salary for land workers. There were even women who disguised themselves as men to work on the ship, and many girls dreamed of marrying a whaling ship captain. Whalers had become the embodiment of light to some extent, and the whaling industry had become the most respected profession.
Around 1846, nearly half of all American fishing vessels were engaged in whaling, and 735 of the world's 900 whaling ships were American.
One can imagine how developed and crazy the American whaling industry was at that time.
According to statistics, the number of whales killed in the world in the 19th century alone was conservatively estimated to be more than 4 million, with an average of 11,000 whales killed each year! This number is several times more than the number of whales killed in a year by all countries that allow whaling in the world today!
In that crazy era, whales were almost hunted to extinction.
If American Colonel Conon Drake had not drilled a modern industrial oil well in Pennsylvania, and if petroleum had not replaced whale oil in the following century, whales would probably have been extinct by now.
Yes, Colonel Conon Drake is the savior of all whales in the world, and his photo should be hung in those mysterious whale graves in the oceans around the world...
Whale oil is not only an excellent oil for lighting, but also an excellent oil for anti-corrosion. Hundreds of years ago, many precious items that needed to be preserved for a long time were painted with whale oil to achieve the effect of anti-corrosion and moisture-proofing, which was not much worse than paint.
Especially in recent years, many shipwrecks salvaged from the Greenland Waters and the North Atlantic Ocean have contained many precious items that have been preserved intact because they were soaked in whale oil.
The Japanese obviously knew the function of whale oil, which is why they used barrels of whale oil to preserve these iron boxes.
He used his consciousness to open the whale oil and gathered it together, forming a huge oil bubble and letting it float in the space. Then Yang Jing took out the four iron boxes.
These four iron boxes are made of ordinary steel plates, all with hidden locks. Because they have been soaked in whale oil, these iron boxes are well preserved.
The secret lock on the box could not stump Yang Jing. In this space, Yang Jing's consciousness was the supreme God.
But after opening these boxes, Yang Jing, who had great hopes, was completely disappointed.
Originally, it was thought that these boxes contained some precious information. After all, before opening these boxes, Yang Jing had used his perspective skills to see that the boxes contained some paper products. At that time, Yang Jing thought they were important military information of the Japanese army at that time.
In modern times, even some confidential military information from World War II is quite valuable. After opening it, Yang Jing was disappointed to find that these things were just some ordinary family letters - letters between senior officers of the Japanese army stationed in Rabaul, the Solomon Islands and other places and their families in Japan.
Although "the war has been going on for three months and a letter from home is worth a fortune", isn't it too much for your senior Japanese officers to use this method to deliver letters from home?
However, Yang Jing still had some hope and used his consciousness to look at these family letters. He opened them one by one, and when he saw that they were indeed family letters, he immediately cleared the space.
Yang Jing knew a little Japanese, thanks to a professor who taught modern economics in London who was from Japan. So Yang Jing learned a little Japanese to get enough credits, but he could only read some Japanese characters. If he was asked to speak Japanese, Yang Jing could only say "Kunijiwa", "Sanyounala"... Of course, he could also understand "Yameidi"...
