"Not only is this whale huge, but more importantly, it's full of treasures!"

Liu Jin also drew a whale on the blackboard behind him as he spoke.

"The skin of the whale is different from the skin of ordinary marine fish, the whale has no scales, the texture of the whale skin is very soft, there is fluff on the surface, and there are beautiful patterns on the skin, which is the best quality leather."

"The meat of whales is similar to beef, very nutritious, and very delicious, everyone knows that this cow is not huge, but in fact there is not much meat, and cattle cannot be slaughtered at will."

"This whale meat is about the same as beef, but this whale can have tens of thousands of catties of meat casually, which is equivalent to hundreds of cows."

When he said this, Liu Jin also paused slightly, giving these people some time to digest it.

"Hundreds of cows?"

When everyone present heard this, they suddenly widened their eyes again one by one, cattle are extremely valuable resources in this era, the Ming court is forbidden to kill cattle, cattle even have a yellow book like people, and every cow is registered on the official side.

If the cow dies of old age or illness, the owner needs to report to the official side, and only after the report can the cow be divided and eaten, in addition, it is illegal to kill the cow.

From here, you will know the preciousness of cattle.

In later TV dramas, it is impossible to go to the store to ask for two catties of beef at every turn, of course, it is estimated that this is also to set off the gold of beef.

Now Liu Jin has equated whale meat and beef, telling everyone that the meat of this whale can be equivalent to hundreds of cows, and everyone immediately knows the value of this whale.

"How is this possible?"

Zhou Jing couldn't help but whisper to Li Dongyang beside him.

"I can't believe it, but judging by the usual style, I'm afraid it's mostly true."

Li Dongyang thought about it and replied.

"In addition to the fact that this whale has a lot of meat, and the meat is as nutritious as beef, it also has a lot of oil."

Liu Jin continued to preach.

"The whale oil contained in this whale accounts for about 30% of the whale's weight, and a whale can easily boil out tens of thousands of catties of whale oil, and the oil that can be boiled out of this whale is equivalent to the lard taken from thousands of fat pigs."

Liu Jinyu is not shocking, and when he talks about whale oil, he once again compares the most common pigs in everyone's daily life.

Pigs are also extremely valuable assets in this era, because the grain production is limited, so the family can afford to raise pigs are considered well-off.

As for pork, ordinary people can only eat a little bit during red and white ceremonies and New Year's holidays.

Now Liu Jin actually said that the oil boiled out of this whale can be equivalent to the oil boiled out of thousands of fat pigs, and suddenly countless pigs appeared in everyone's minds, and they had a more intuitive concept of the value of this whale.

The meat is equivalent to hundreds of cows, and the oil is equivalent to thousands of pigs.

"Thousands of fat pigs...."

Zhou Jing was speechless again, and always felt that Liu Jin was talking nonsense, but after listening to Liu Jin, he was very much looking forward to seeing this kind of whale and seeing if it was true.

"If this whale really said that, then I should open the sea ban."

Zhou Jing said very softly to Li Dongyang beside him.

"It seems that this time, we don't have to leave in a hurry, we can stay here in Tianjin for a few more days, and I also want to see if this whale is the same as he said."

Li Dongyang nodded, and really wanted to see what this whale looked like in his heart, and see if it was the same as what Liu Jin said.

"This whale oil is not edible, but its oil can be used for lighting, whale oil burns without any smoke and dust, it is the best lighting oil, and it burns for a long time, I don't know how many times stronger than the candles we use now."

"In addition to being used for lighting, it can also be used to dye cloth, as lubricating oil, and can also be used to make soap, which is what everyone usually uses when taking a bath, compared to lard, the quality of soap made of whale oil is better, and it is very widely used and extremely valuable."

Liu Jin drank his saliva and continued to talk.

"The whale's feces are precious except for meat and oil."

When he said this, some people below didn't believe it, and some people said with a smile: "Liu Gongzi, this is too much." ”

"You don't believe me?"

Liu Jin smiled and continued, "Do you know ambergris? ”

"This ambergris is actually something excreted by whales, which is ugly and unpleasant at first, but amber after drying, and can ignite fire, and the flame is blue, fragrant, and tastes the same as musk."

"This ambergris is more expensive than gold, and only the really rich can afford it."

Hearing ambergris, people who don't know are naturally confused, as for Li Dongyang, Zhou Jing and Zhang Mao, they naturally know it, and they have all used it.

"This ambergris is actually excreted by whales?"

Zhang Mao felt that he was going to get goosebumps all over his body, he liked to use ambergris very much, and he often had to light ambergris at home to refresh and wake up, but he never thought that this thing was whale excrement.

"I'm afraid that's probably the case."

Li Dongyang smiled and nodded and said.

"Of course, there is only a very small amount of ambergris in the excrement of this whale, and most of the excrement naturally cannot be ambergris, but it still has a great effect, and it can be used to fertilize the field and increase the yield of grain after drying."

Liu Jin finished speaking, and at the same time, he also looked at Li Dongyang, Zhou Jing, and Zhang Mao from the corner of his eye, Li Dongyang knew each other and met, although Zhou Jing and Zhang Mao had not met, but looking at this, being able to stand with Li Dongyang was most likely also a minister in the court.

The reason why Liu Jin wants to talk about the role of whales, and also compares hundreds of cows and thousands of pigs, naturally he also has his own good intentions.

If these important ministers can support the opening of the sea ban, they will naturally get twice the result with half the effort, and this lesson is actually more for Li Dongyang, Zhou Jing, and Zhang Mao.

"Okay, that's all for today, if you want to see whales, build this whaling ship as soon as possible, and let you eat whale meat instead."

Then Liu Jin also smiled and said with a lot.

"Liu Gongzi, this whale meat is still fish meat, can you give us something else."

Someone said to Liu Jin with a smile.

"If you have meat to eat, you can pick and choose, I think it's best to starve you kid."

As soon as this person's words fell, someone couldn't help but scold, it had only been a few days and he had begun to dislike the unpalatable fish.

"I'm not tired of eating fish."

"I have three meals a day this day, and I eat fish and meat at every meal, and I really want to vomit."

The man said weakly.

"Haha, don't worry, I promise that this whale meat must be similar to beef, and the taste is much better than other sea fish meat, but you will definitely get tired of eating it."

When Liu Jin heard this, he couldn't help but smile and replied.
