Li Yu learned from Lu Yuanqing that the northwest coast of Xuansu Sea is mostly a continuous coastal mountain range, with high mountains and dense forests, making it difficult to enter the inland, and there are only a few narrow valley plains that can be used as a foothold.

Sailing along the coast of five or six thousand miles, as you can see along the way, the so-called five or six hundred miles of the so-called driving Du Mei country in the north of Murowei is not boasted, but it is a more sparse population than the ghost country, and the people who live here are independent of each other and exist in a barbarian tribe that does not know what the country is.

From north to south, every thousand miles, the tribes inhabited by each other do not understand each other's language, customs are very different, and calling it a country is just a far-fetched mixture of outsiders who do not understand the truth.

"I want to find a place to build a city and reclaim along the coast, I wonder if Manager Lu has any good suggestions?"

The so-called Driving Dou Mei was actually the northern part of the Khabarovsk Krai of Russia and the southern part of the Republic of Sakha.

Although Li Yu doesn't know how big the specific area is, it should not be a million square kilometers, and it is not too much to control the area with a better natural environment along the coast in advance. In the future, with more abundant manpower, we can learn from the methods of the Russians who annexed Siberia in later generations, and gradually encroached on the interior by going up the river.

Lu Yuanqing and Hu Anjun glanced at each other, and they knew it in their hearts. Sure enough, His Royal Highness had the heart to drive the territory of the Meiguo Kingdom, but fortunately, the two of them had been prepared when they explored the foreign land, and spent some time focusing on surveying areas with good terrain and natural environment, and marked them in red in the map they drawn.

Lu Yuanqing, who led the fleet to inspect the map drawn by Lu Yuanqing, who drove the coast of the country, pointed to the two points marked in red in the map with his index finger and said: "Your Highness, although the coastline of the country is long, there is only one river valley in the north and south that is suitable for habitation and has a slightly better environment. The two are separated by more than 1,000 miles, which are blocked by the wild mountains, and only sea ships can connect the two places. Although it is a river valley, Yichen personally feels that the local climate is cold, even in summer, the temperature is only high in the late spring of the Central Plains. The local deer herd and live by fishing and hunting, and no one cultivates them. His Royal Highness wants to reclaim the land, but according to the minister's view, he may not be able to grow food. ”

Lu Yuanqing unceremoniously pointed out that Li Yu's assumptions are unrealistic and unrealistic, the local climate is not suitable for the growth of crops at all, and the further north you go, the lower the temperature.

Li Yu rubbed his forehead and stared at the two river valleys on the map that Lu Yuanqing said had a good environment. The river valley in the south was not discovered by Lu Yuanqing first, but the northern expedition team Long Zhi, who was rescued from Libu in Heishui Ya County a few years ago.

Both accounts indicate that there was a tribe of the Vedians who called themselves the Vultures, and that the river in the valley was called the Udi River.

Li Yu originally wanted to build a city here first, but Lu Yuanqing's basin of cold water poured down, and the originally fiery heart gradually cooled, and the memories of his previous life were poured up.

This should be the location of Chumikan in Russia in later generations, the latitude is about the same as Moscow, it stands to reason that Moscow can grow grain wherever it is, and the Udi River valley at the same latitude is close to the sea, shouldn't the temperature be too low to grow grain? The three Nordic countries are even higher latitudes, but they can also develop food cultivation.

"That's right, ocean currents." Li Yu suddenly thought.

Hu Anjun and Lu Yuanqing didn't know why, and muttered in their hearts what is the ocean current? What did His Highness think about at the end? What does this have to do with whether or not you can reclaim along the coast?

It's been fifteen years, so much so that Li Yu has almost forgotten the ocean currents that influenced the global climate and created different climates and environments in his previous life in junior and high school geography.

Thanks to the continuation of the Gulf of Mexico Stream to form the North Atlantic Current, the temperature of Western Europe and Northern Europe has warmed and humidified, and the impact has been extended to the Arctic Circle.

However, in the Far East in the eastern part of the Eurasian continent, a southward Kuril cold current near the Kuril Islands blocked the northward Japanese warm current (Kuroshio) to the northeast, forming a North Pacific warm current flowing to the west coast of North America.

Even the coasts of Kamchatka and the Xuanfu Sea at the same latitude as Europe are much cooler, which is not suitable for the growth of crops.

After Li Yu figured it out, the original plan to build a city and reclaim along the coast of Qidumei was as Lu Yuanqing said, it was simply impossible. You can't let the soldiers and civilians of the cantonment learn from the local natives to live by fishing and hunting, right?

Just because you can't do it now doesn't mean you can't do it in the future. The key is to have food crops that can be grown in high latitudes and low temperature climates, and the only food crops in the world that meet this condition are potatoes from South America.

As for the vegetables that can be grown, there is no shortage of them, such as Bai Xiang, the originator of Chinese cabbage in later generations, but it has not yet been cultivated into the cabbage that is familiar to later generations.

At this point, Li Yu felt that after the end of the Silla War, it was necessary to organize vegetable growers to cultivate cabbage. The first is to solve the demand for winter vegetables in the Andong area, after all, Chinese cabbage can be stored for a long time in winter, and it is also good to make kimchi like the Koreans of later generations.

Thinking of this, Li Yu sighed, the colonial drive to sleep, marching into the interior of Siberia, and it had to wait for the opening of the route to South America to bring back potatoes before it could be implemented.

The Chinese are an agrarian people, and their habits for thousands of years have made it difficult for them to adapt to the life of perennial fishing and hunting. In ancient times, productivity was low, and a city that only relied on fishing and hunting without food crop production would definitely not last long.

This is why it is difficult for civilization to emerge in the Far East and establish a kingdom in the true sense of the word.

Without potatoes, it is impossible to colonize and drive away for the time being, but for the conquest of the Wandering Ghost Country, Li Yu will carry out it in the coming year anyway.

The location was chosen in the bay where the Xuansu Sea expedition clashed with the wandering ghosts, and the local wandering ghosts were slaughtered by the expedition team, and the colony was unlikely to be attacked by the wandering ghosts in the coming year.

Regarding His Royal Highness's plan to colonize the country of wandering ghosts in the coming year, Hu Anjun suggested: "The country of wandering ghosts is thousands of miles away from the nearest prefecture in Hokkaido, Ishikari Prefecture, and it takes half a month to sail, and there is no supply point on the way, which is not conducive to the navigation of the immigrant fleet. ”

"Your Highness should first establish a supply point between Hokkaido Island and the Ghost Country, so as to provide a berthing and rest for the fleets to come and go, and replenish the water."

Li Yu thought about it, it was imperative to establish a stronghold along the way to the Wandering Ghost Country in advance, but the selection of the stronghold required the advice of Hu Anjun and other people who were on the ground, so he asked: "I wonder if the two chiefs can think about where the supply points along the way should be established?" How many need to be built? ”

Hu Anjun replied: "At least four, except for one of the largest islands in the archipelago between Hokkaido and the country of Ryuki, the remaining three should be built on the coast of Hokkaido Island in the south, southeast, and north directions suitable for reclamation. As for the exact location, the minister and Brother Lu had discussed that it should be placed in these four places. ”

As he spoke, Hu Anjun unfolded a map from Hokkaido to the country of Liugui, and pointed out to Li Yu the locations of the four supply points that should be established.

Li Yu discovered that the three supply points in Hokkaido were the locations of Hakodate, Kushiro, and Wakkanai in Hokkaido. Except for Wakkanai, which is located in the northernmost part of Hokkaido, the environment may be poor, and the other two places are excellent environments.

"It seems that the development of Hokkaido is going to be accelerated!" Li Yu looked at the map and muttered.

Located on the supply point that should be established on the archipelago between Hokkaido and the Ghost Country, Li Yu stared at the big island chosen by Hu Anjun, and pondered for a long time before estimating that it should be the island of catch.
