Marin sent people to study how to solidify maple syrup, which, although called sugar, is actually similar to honey and is in a liquid state. Marin and Garland gathered all the master chefs on Cape Breton Island, and they couldn't turn maple sugar into solid pellets. Using saltpeter to make ice, it can freeze maple syrup, but it will immediately liquefy again at room temperature.

"That's not right, I've eaten maple candy cubes in a Western restaurant in my last life!" Marlin scratched his head a little.

Actually, this is Marin's loneliness. The so-called "maple cubes" in Western restaurants are not simple maple sugar, but mixed with butter, sugar and honey, not pure maple sugar.

Marin did not give up, and took a dozen barrels of maple sugar that had just been extracted to the North American twin islands and found Leonardo da Vinci......

He thinks that it is the masters of Cape Breton Island who are too good to make maple candy cubes. So, he decided to find the greatest god of this era, Leonardo da Vinci......

As a result, Leonardo da Vinci and his wife, Lisa, ate half a bucket of maple sugar and failed to make it solid......

Marlin was very frustrated, if it was not made into a solid, it would be inconvenient to preserve. After all, liquids are more susceptible to spoilage than solids. Marlin remembers that maple syrup has a relatively long shelf life, which can reach 4 years, which is longer than the 18 to 24 months of ordinary syrup-based substances.

However, with a shelf life of 4 years, it is a high-purity maple syrup, and there is basically no impurities and moisture. However, in this day and age, it is difficult to obtain high-purity maple syrup. Ordinary quality maple syrup is no different from other types of syrup. Not only that, but the preservation of maple syrup also requires an airtight container, processed like a can, and placed in a cool, dry place...... In conclusion, liquid maple syrup is not easy to preserve......

In addition, the most important thing is that if the maple syrup is taken back to Europe and sold, it is a bit difficult to tell where it came from......

You say it's sucrose, why don't you sell it as a solid? You say it's honey, but it doesn't taste right......

If you confess the source, maybe someone will come and rob Canada......

So, Marlin was extremely distressed and didn't know what to do with the maple syrup......

Fortunately, the da Vinci family did not eat half a bucket of maple sugar for nothing, and Da Vinci finally proposed a solution - since it can't be sold alone, why not mix maple syrup with other goods and sell it together?

For example, if you mix maple syrup with rye two-pot head (i.e., whiskey), the taste is ...... Much stronger than mixed with brown sugar......

Moreover, the rye two-pot head mixed with maple syrup will have a faint amber color, and it looks good. Unlike the rye two-pot head mixed with black sugar, it is a little black and the color is very unsightly......

So, the first use of maple syrup was decided - mixed into the second pot head to enhance the taste!

Then, Leonardo da Vinci suggested that maple syrup could be mixed into foods such as bread to enhance the taste. The bread tastes great with maple syrup and cream......

Marin frowned a little at this suggestion. Why? Bread has a short shelf life! If bread is not vacuum-packed, it has a shelf life of only a few days. With the addition of maple sugar, it is not cost-effective. And if it is provided to a bakery, it is not clear where the maple syrup comes from......

"All I have to do is make a suggestion, and it's up to you to decide. Seeing that Marin didn't take his advice, Leonardo da Vinci didn't care. I saw him munch on the queen's bread with maple syrup and cream. Halfway through eating, the old guy was so playful that he actually pinched the bread into a small lump. Then, laughing like an old child......"

Marin looked at Leonardo da Vinci's mentally retarded behavior, but was inspired:

"Clenched into a small lump...... Compress...... Yes! Compress cookies! Marin suddenly had an inspiration.

Marin remembers that compressed biscuits were the most important basic ration for the army. Moreover, the biggest feature of compressed biscuits is that they have a long shelf life, which can reach more than 3 years. In fact, if it is well preserved, it is said that some people can eat it for 10 years.

Marin now has oiled paper in his hand, as long as it is packaged, the air is pressed out, and it is sealed and heated to sterilize, so that the compressed biscuits can be stored for two or three years.

Moreover, biscuits with maple syrup can greatly enhance the taste of compressed biscuits and avoid discomfort after eating. Maple syrup is already rich in minerals, and it is added to compressed biscuits with little nutrition, and it is a proper high-grade military ration. Not only can the army use it on a large scale, but the voyage can also bring a large number of maple sugar compressed biscuits. Compressed biscuits with maple syrup not only taste better, but are also nutritious.

"Good, good! With these two uses, you don't have to worry about having nowhere to consume maple syrup! Marin quickly took out his notebook and jipped it down.

Of course, with these two major uses, the demand for maple syrup is actually not too large. Therefore, Marin adjusted his plan in time - no longer seeking contact with the Indians on the main road, and bought maple sugar on a large scale. In the case of a greatly reduced demand for maple sugar, but the production of maple sugar on Cape Bretton and Newfoundland is enough to consume. However, if the technology of maple sugar cubes is developed in the future, it is also possible to unite with the Indians to increase maple sugar production at any time. Anyway, there are so many sugar maples in Canada that the Indians don't like to cut down trees to reclaim the land......

……

After solving the problem of maple sugar use, Marin didn't say a word, and took the Da Vinci family on the ship, ready to bring them back to China. Because, Marin found that there were too few people who could communicate with him in this era. Only a genius like Leonardo da Vinci can keep up with the advanced thinking of a time-traveler like him. There are a lot of things, and Da Vinci has to help him do it. For example, the new type of steering wheel needs Leonardo da Vinci's help to study. What is the steering wheel that I asked the watchmakers to study? It is actually a combination of gears and copper rods, which really makes full use of the watchmaker's expertise. However, that steering wheel system was not labor-saving enough and was expensive to build. So, Marin plans to let Leonardo da Vinci make a new ......

"However, the application of the steam engine on my side has not yet been completed...... Leonardo da Vinci weakly objected.

"Don't do it, that's not a rush now. Hurry up and pack up and follow me, if you don't accept it, you will be knocked unconscious and taken away! Marin waved his hand impatiently. Karn, who was beside Marin, also rubbed his wrist, as if he was really going to come up and knock Ada unconscious......

Remembering the nightmarish experience last time, Leonardo da Vinci honestly went to pack up and follow the ship......

When he arrived in New York, Marin was relieved to find that New York Harbor was already under construction. Manhattan Island, on the other hand, has now been reclaimed as an agricultural base and is thriving......

After inspecting Manhattan Island, standing on the roof of the castle, Albert asked with confusion:

"Second brother, why is this island called Manhattan? Also, why is this called New York (New York)? ”

Marin was stunned and said:

"Need a reason?"

"Don't you need it?" Albert tilted his head, puzzled.

"Do you need it?"

Albert retreated......

……

"Looks like it's time to go back to Europe!" I've seen it in New York, but it's not much. The deep mountains and old forests are not much different from the forest areas of later generations.

It was only after boarding Liberty Island, where the Statue of Liberty would be housed, that Marin suddenly said to Albert:

"This small island is very suitable for placing a statue, a very tall ......"

Albert nodded, but then asked:

"The statue of God or Jesus'?"

"No, my!" Ma Lin said lightly.

Albert covered his face suddenly, he felt ashamed for Marin......

However, Marin asked in a flat tone:

"What? Questions? ”

Albert suddenly remembered that he was not only Marin's younger brother, but also Marin's subordinate officials. As a subordinate, you have to carry out the will of the leader......

So, although he felt shameless, Albert replied with confidence:

"No problem! Also, I'll arrange for the civilians to propose a statue for you, not myself! ”

Seeing his younger brother like this, Marin nodded with satisfaction. But he also explained:

"The matter of the statue is not in a hurry for the time being, you first lay the foundation on the island. Wait until I've negotiated with a master carver named Michelangelo in Italy before I ask him to carve. Then, it was transported here by boat and placed on the foundation. By the way, the foundation is high, facing south, so it's best to let ships entering New York Harbor see it from afar! ”

"Yes, yes!"

……

After returning to Manhattan Island, Marin thought about it and called Albert again:

"I'm going back to Europe, you go and arrange the carpenters to build 300 coffins!"

Albert was taken aback:

"Second brother, why do you want so many coffins?"

"I'm going to show the Europeans! You also know how fertile and endless the land is here. If other European countries covet it, it will be difficult for us to resist. So, I'm going to exaggerate the danger here. These 300 coffins were made to carry them back for everyone to see. I'm going to let all of Europe know that the natives here are savage, fierce, and powerful. In this way, they don't dare to covet this place casually! ”

"Understood!" Albert turned and went to gather the carpenters to build the coffin.

Marin, on the other hand, arranged for 300 fighters to stay, which was counted as the "dead list". In fact, the families of these 300 people, Marin will soon be sent to the Americas to reunite with them.

Marin plans to hold a state funeral for these 300 "fallen soldiers" after returning to China and in front of the envoys of various countries, so as to make the noise as loud as possible, so that everyone can know that the Americas are "very dangerous......

Anyway, no one will open the coffin to perform an autopsy, as long as the accompanying soldiers are told, no one will know if the Americas really died 300 soldiers of the North Sea Kingdom......
