The knowledge of military geography from a thousand years later frightened everyone on the lookers, and Xiong Jing, a boy with drooping hair, had a bit of Zhuge Liang's demeanor. The group stared at the map at first, then rolled their eyes, and finally all looked at Lao Suo. Lao Suo is also an extraordinary person, the inheritance of the future generations of "Crane Crown" nineteen articles are written for him, and in the Chu State, he has no name and no surname, only to the Crane crown as the number, three generations of Chu kings respect him, but he appeared in the school palace, but not for Xiong Jing.

"What Zijing said, should it be based on the hometown of Wuyue in Jiangdong?" The crane crest groaned and knew the intention of Xiong Jing.

"Exactly." Xiong Jing sneered - the military geography after a thousand years may not be suitable for the present, and Lao Su has already seen the problem.

"Jiangdong is vast and sparsely populated, with rice, soup and fish, and there are no people who are frozen and hungry, and there is no home for daughters. In the end, Wu Yue destroyed the country, and there were still less than 200,000 households. The Yue Kingdom was destroyed, and the king had the intention of dividing it, but this matter could not be done. "Crane Guanzi remembered the Wu Qi reform more than a hundred years ago, when he planned to divide the nobles of the public office in the border land, but unfortunately it didn't work." Today, our Chu country is focused on the north of Huaishui. Even if Jianghuai can be defended, the people of Huaibei are difficult to move; Even if they move, they will not have any land to stand. ”

Jiangdong was rich after the Qin and Han dynasties, at least after the Qin Dynasty, and if you want to use Jiangdong as a base and divide the world, it is impossible now. Xiong Jing is a direct copy of the geographical population of later generations, so ignore this issue, but there are also people who do not believe in evil.

"Sir, my ancestors bask in the wind and rain, and the blue wisps and the road, so that there is today's great Chu, Jiangdong can have rice and soup and fish, how can it not be turned into fertile land?" Zhao is a young man, and young people always feel that anything is possible.

"Ridiculous." The crane shook his head repeatedly. "In the Jiangdong regions, the tide is flooding, and Daze is colluding. Without the power of the whole country, there is no way to achieve Qianmo, and without a hundred years of work, there is no mulberry field. It's late! It's late!! ”

"It's not too late, if there is corn, sweet potatoes, and ......potatoes from Dongzhou," Xiong Jing finally seized the opportunity to start advertising, "The land of Jiangdong can also be the foundation." The farming of Dongzhou does not need to be strange, there is no need for irrigation, there is soil, it can be ripened in a few months, and the yield is twice that of corn. ”

When the "Dongzhou ......" drew the world map, Xiong Jing had already named the Americas as the East Continent, Asia as the Central Continent, Europe as the Western Continent, Africa as the South Continent, and the Antarctic as the Cold Continent. As for Australia, when I think of the 500 waste of the Australian Song Dynasty, it is called the Waste Island - anyway, there is no great product on it. Except for Zhao Xuan, the others were very confused when they first heard the name of Dongzhou, and only the high-crowned person who had been silent asked with his head: "Is it for Fusang?" ”

"Fuso?" Xiong Jing thought of neon, and was about to shake his head when the other party said: "The ancient people once crossed the sea in the east, and the one who returned said that there is a naked country in the east of the sea, and there is a country in the southeast of the naked country, and the boat can be reached in a year." ”

"Huh?!" Xiong Jing couldn't help but kneel and look at him in disbelief. If you go to the Americas and come back, I'll give you a lung! "Excuse me, sir, did you bring back any crops?" Xiong Jing asked again.

Compared with Xiong Jing's excitement, the high-crowned person remained silent. "Ancient things have not been heard in detail, only tortoiseshell records."

"Tortoiseshell Chronicles?" Thinking of the tortoiseshell bone fragments on the way here, Xiong Jing somewhat understood.

"Mr., Ji Lingjun and Bu Yin have been compiling scriptures for ten years, and the books record the mountains and rivers, creatures, and demons at home and abroad. Zijing said that day about all continents in the world, Mr. was quite surprised, so he invited Zijing to come here. Zhao Duan explained the reason why the crane Guanzi invited Xiong Jing to come here, and the person next to him immediately opened a bamboo slip, and the three words on the left made Xiong Jing's heart jump suddenly: Nanshan Jing.

"The Classic of Mountains and Seas?!" Xiong Jing's face changed greatly, and then he looked at Que Guanzi, Yin Hou, Bu Yin, and Zhao Duan, and finally looked around, he never thought that the Classic of Mountains and Seas was compiled here.

"I wanted to call it the Book of Mountains and Seas, but Zijing called it the Book of Mountains and Seas, which is a very good name." Ji Lingjun said with a smile, he had seen Xiong Jing at the court meeting that day, and he also supported Xiong Jing as the prince because of his position. After speaking, he saluted again: "Ji Lingjun has seen the prince's feet." ”

The high-crowned man also smiled, and he also saluted: "Bu Yin Guanyu has seen the prince's feet. ”

"No, I don't dare." Many of the gentlemen in the school palace are official teachers - one side is an official and the other is a teacher, and the teacher Xiong Jing is to perform the disciple ceremony, and now the two of them bow to him, and he will not dare to accept it.

"The soup pool is far away, and the corn and sweet potatoes produce twice as much as the corn?" The compilation of the Classic of Mountains and Seas can be put aside, and the most concerned about the yield of crops in Dongzhou is the one who is most concerned about it. Twice as much as corn, it is equivalent to saying that the grain output of Chu can be doubled.

"No, don't dare to say anything." Xiong Jing replied that the yield is no joke. "The yield of corn is low, but the yield of sweet potatoes per mu can indeed exceed 10,000 catties."

"Ten thousand catties?!" This time, it was the turn of the crane crown, and his face changed drastically.

"There are indeed 10,000 catties." Xiong Jing thought that the city mu he said should be different from Chu mu, but after thinking about it again, the city jin is twice as large as Chu jin. According to the yield of sweet potatoes he remembered, there was a yield of 5,000 catties per mu - this is the figure in the "Golden Potato Biography" of Chen Shiyuan, a Qing man who introduced sweet potatoes, or the output of the lower land, and the output of the upper land is said to be more than 10,000 city catties.

"But five catties of sweet potatoes are equal to one catty of corn." Xiong Jing made another addition, he looked at modern history, and when calculating the yield of sweet potatoes in modern times, it had to be divided by five, so that it could be converted into grain. Potatoes have a lot of water.

"There are 10,000 catties per mu, and there are 2,000 catties in five folds for one." Zhao Duan trusts Xiong Jing the most and is convinced of this.

"The yield of potatoes is low, and the yield per mu may be 2,000 catties. The same as sweet potatoes, it must also be five catties for one catty. Xiong Jing said again. Corn does not need to be folded, and the yield per mu may be 400 catties. All three can be planted in barren land, drought and cold tolerance, do not require too much labor by farmers, and do not occupy fertile land, wasteland can be. ”

"Dongzhou is so far away." The crops in Dongzhou are so good and the yield is so high, even Guan Tu sighed.

"Sir, Dongzhou can sail in a year...... Xiong Jing immediately brought up what he had just said.

"This is not what I say, but it is carved on oracle bones, and it is a miracle." Guan Yu explained: "On the East China Sea, there is no distinction between north and south, and there are many fierce beasts. ”

"If you can really go, you can go to Sangu and return!" Everyone who said it was a little cold, but Xiong Jing said categorically that he would definitely be able to do it, and for a while, everyone's eyes looked at it again. "I don't want to swear ......"

"Zijing is not dry." I had long heard that Xiong Jing swore to the king when he made a strong crossbow, and when the crane saw that he was going to swear, he immediately stopped him. "On the sea, how can the boaters distinguish between the north and the south, and how can they vent the wind and waves? If you sail for a year, how can you eat? What is ...... drinking?"

Crane Guanzi asked a lot of technical questions, and he really had to answer them patiently, and he couldn't finish it for three days and three nights. Xiong Jing didn't want to go to the Americas to find any sweet potatoes or potatoes at first, he just wanted to leave the country early before the destruction of the Chu State, travel around the world and wait for the Qin State to destroy the country and come back. But in order to gain support for shipbuilding and navigation, he had to make up these things.

It is not impossible to cross the Pacific Ocean - it is indeed difficult for a nautical layman, but he is not a layman. One of the things about navigation is the boat, and the other is navigation. As far as ships are concerned, Zheng He's fleet, which has no keel ribs and only a water compartment, can sail to the Western Ocean, and 19th-century sailing ships with keels and ribs can even gallop on the sea.

Navigation, sextants, ship clocks, etc., may not be possible to be made in a short period of time, but there are no sextants and quarantiners, and no quadrants can be used with Viking sun-watching boards. The most important thing is that as long as you get to the right place at the right time, the ocean currents and monsoons will automatically send you to the Americas and back again. This is how the Spaniards crossed the Pacific Ocean and traded galleons.

Although Xiong Jing could not afford to buy the British Navy's "World Ocean Routes" (chapters 8-10 of which are sailing routes, specially used for low-speed cargo ships), he still remembers the Pacific routes, the Indian Ocean routes, and the Atlantic routes, which were classic routes discovered by early navigators. Give him a qualified ship, and some more qualified sailors, and he will be able to cross the Pacific Ocean to the Americas, and then return with the currents in May and June of the following year.

"It's hard to put into words." Xiong Jing took a deep breath, "The ship is very related to the sea, and it can't be described one by one if it's not a month. As mentioned before, only with the power of one county can be shipbuilding and navigation in all continents, then you can take the three valleys of the East Continent, find the horses of the West Continent, and get the gold and stone of the South Continent. A gentleman should ride the wind and waves, watch the wonders of the mountains and seas, and live the world, how can he sit in a well and watch the sky, make a car behind closed doors, and follow the clouds? ”

The young man's eyebrows were raised, but the eyebrows of the young man were raised, but the eyebrows of the Crane Guanzi, Ji Lingjun, and Guanyao were tightly locked.

Xiong Jing said again: "The so-called world is just a corner of the Middle Continent, with the sea in the east, the grassland in the north, the yellow sand in the west, and the miasma in the south. Qin State to the west has the land of the Yellow Sand of the Western Regions, at the end of the Yellow Sand there is the country of the Queen Mother of the West, over the green mountains, you can reach the two rivers of Daxia, and then to the west, there is Persia and the sea in the middle of the earth, thousands of miles to the south, and there are Nanzhou and Hanzhou across the equator. ”

Since he talked about the equator, Xiong Jing simply increased his strength, and after he coughed, he tried his best to raise his voice: "Today's people think that the earth is the square and the sky is the garden. As everyone knows, the continent is also round. The surface of the water is the plane, but why does the boat in the water see its head first and then its belly? Why does the shadow become shorter the further south it goes, and the longer it gets the further north it goes......"

"If the earth is round, is the sky square?" Guan Yu interrupted, he, including Crane Guanzi and Ji Lingjun, didn't seem surprised by Xiong Jing's theory of the roundness of the earth.

"The earth is round and the sky is also a garden." Xiong Jing replied that this was true, and he did not want to touch Gai Tianzhi's words.

"If the earth is round, how can a man stand on the earth?" The crane crest interjected.

"The center of the earth is strong, and all things fall to the ground when they hang in the air." Xiong Jing pushed the bamboo slip off the table. "It's like this everywhere on the earth."

"Force?" The most common heavy objects landing on the ground have a different kind of charm at this time, which is a question that no one has ever thought about - why Shujian would fall to the ground instead of flying into the sky after leaving the case.

"Exactly." Xiong Jing wanted to continue to popularize Newton's three laws, but he yawned a few times in a row, and he was sleepy. "The three gentlemen, the sons and gentlemen, are not sleepy, can we talk about it another day?"

Xiong Jing's yawning demeanor made Que Guanzi a little dazed, just now he felt that he was talking to an adult, and now he found out that the other party was just a child, this feeling was very uncomfortable. After Zhao Duan sent Xiong Jing out, he sighed and asked, "How is Prince Jing?" ”

"Born to know, the talent of the sky, set up as the king of Chu Bixing." Ji Lingjun also sighed.

"If it's not a saint, it's a demon." Guanyu was not as excited as Ji Lingjun, and after speaking, he looked at the girl he brought with him with complicated eyes - he noticed that Prince Jing liked Xuanqing.
