Li Er looked at the globe in his hand in disbelief, his bound heaven and earth mind could hardly imagine that this ball was the world.

"You're saying that all the terrain on this ball is real?" Li Er's tone was a little panicked.

"Exactly." Xu Yang said proudly.

"How is it possible, since ancient times, the sky is round and the earth, the sun, the moon and the stars, how can it be a ball?" Li Er still couldn't believe it. Then he asked, "You said that the world is a ball, so don't the people who live under the ball fall into the endless void?" After that, he stared at Xu Yang carefully, waiting for his answer.

Xu Yang seemed to have a plan to deal with it, and took out an apple from the box for a long time.

He exclaimed, "The fruit ripens on the tree and falls to the ground." With that, as soon as he let go of his hand, the apple fell to the ground.

Li Er still looked at him inexplicably.

Xu Yang seemed to be possessed by Newton at this time, and he asked softly, "Why do apples fall straight down when they are ripe?" And not to fly into the sky? So there must be something dragging it, dragging it to the ground, this force of pulling it, by the tenth generation of my Guigu faction Wen Guiguzi Newton called gravitational force, everything in the world has gravitational force, the greater the mass, the greater the gravitational force, the ball we live in is big enough, so it can suck everyone firmly on it. ”

Li Er's eyes widened, he was still absorbing what Xu Yang said, which seemed unreasonable but unassailable.

Li Er sighed helplessly, he found that he couldn't refute it, the objects in the high places would fall to the ground, and no matter how high the person jumped, he would eventually return to the ground. It's as if there's something called gravity that drags them.

"Tell me, why is my Datang so small on this ball? What kind of Arab Empire and Byzantine Empire are they, and they are actually bigger than the vast territory of my Tang Dynasty? Li Er started another topic.

"Your Majesty, those are all barbarians, the Arab Empire is what the Tang Dynasty called the Great Food Country, the people there now believe in Islam, holding a knife in one hand and the Koran in the other, they are in the period of the four major caliphs, its territory stretches from the Indus River in the east and the western border of China, west to the Atlantic coast, north to the south of the Caspian Sea, south to the Arabian Sea, and it is also a plot of Asian and African superpowers.

This is Europe, and now there is a phenomenon of extreme ignorance, where everyone is blindly religious, and those who advocate the study of science and truth are burned alive, and the Arab Empire is already eyeing this land.

This is the Byzantine Empire, which is what the Tang Dynasty called the Roman State, an Orthodox country whose territory once included western Asia and northern Africa, and at its peak also included Italy, Syria, Palestine, Egypt and the Mediterranean coast of North Africa. They are strong, they advocate force, and they are not very easy to conquer. ”

Li Er listened very attentively, it was the first time for him to understand the world so novelly.

In the past, he thought that he was already the master of the world, as long as he defeated the Turks, the land area would have reached the highest in the world, but now he found that he was like a frog at the bottom of a well, there was land overseas, and there were countries on land, and the country he had worked hard to build was not as big as others.

"Why do I hear your tone as if you want to conquer these countries?" Li Er looked at Xu Yang with interest and asked.

Xu Yang saluted respectfully and said: "Under the Putian, it is not the king's land, and the shore of the land is not the king's minister." The minister watched the sky at night on the overseas mountain, and found that the Oriental crape myrtle star was extremely bright, knowing that my Tang Dynasty would have an emperor born through the ages, and he specially went down the mountain to assist His Majesty, conquer the world, and live for centuries. ”

"Hahahaha!" Li Shimin's hearty laughter that he had never had before also resounded in the hall, "What a leader on the shore of the land, it is not the king's minister!" can be assisted by the true legend of Guigu, he is really a hero in the world, and he is in my place! ”

I can see that Li Er is really happy, Xu Yang Nunu mouth, the ancients don't deceive me, Li Er is really a narcissist.

"Xu Guigu, what do you think about me governing the world?" In addition to being excited, Li Er did not forget to get down to business.

Xu Yang Baidu has read the information, and the things that Li Shimin did to appease the people can be described as a mess.

He said confidently: "Your Majesty should call on the grassland people to return to the Central Plains, reduce the feudal kings, reduce the officials, streamline the institutions, recuperate, reduce taxes, and for the people, we must appease the people to be quiet, persuade the farmers to teach the mulberry, do not take away the agricultural time, and rest with the people, so that the world can be governed." ”

Li Shimin was overjoyed when he heard this, he had all these policies, but there were still a lot of obstacles in the court, and he had to eradicate them one by one before he could implement them.

"But" Xu Yang suddenly took a turn for the worse.

"But how?" Li Er hurriedly asked.

"This can only rule the world, and it is still wishful thinking to conquer the world." Xu Yang slapped his face unceremoniously.

Li Er didn't care about Xu Yang's little revenge, and hurriedly asked, "Then what should I do to conquer the world?" ”

Xu Yang looked profound, and said: "Promote industry and commerce, improve education, research and development of science and technology, and conquer the world." ”

A major event recently happened in Chang'an City, the legendary Guigu disciple has appeared, I heard that it is the twenty-first true disciple of Guigu, which has spread throughout Chang'an, His Majesty Xià and this Guigu disciple discussed in the imperial study, from noon to midnight, even the meal is eaten together, this is from the palace, there is no falsehood.

I heard that this ghost valley disciple came from overseas immortal mountains and brought many divine objects, what immortal elixir, and immortal grass that cures all diseases, of course, the authenticity of these folk fabrications remains to be verified

Xu Yang stretched his waist and looked out the window, the sun was slanting westward, how is this guy, he slept until dark, but he was tired yesterday, Li Er was like a curious baby, and kept asking this and that.

Fortunately, I prepared enough, there are several books in the big box that introduce Dashi and Rome and the surrounding small countries in the Tang Dynasty, these are all reviewed by myself, and any key words have been deleted, Li Er read it with relish, and called this book the book from heaven, Xu Yang politely said that these are all left by his master.

Then Xu Yang introduced the printed cold weapon to Li Er, what three-edged thorns, what Nighthawk flat knife, all pictures were interspersed with text introductions, and Li Er's saliva flowed out when he saw it, and the combat value of these things was better than his own knowledge of the value of the emperor.

Then there are some hot weapons, grenades, rifles, Li Er really can't understand its power, and thinks that it is easy to use without a bow and arrow, but after Xu Yang explained it to him completely, he instantly coveted this modern killing weapon, and he couldn't wait to immediately make one for himself, Xu Yang told him that grenades can be made, but rifles can't, the industrial base is there, and the industrial level of the whole people must be improved first, steam engines, machine tools, and the industrial revolution will be carried out first.

In the end, Xu Yang showed Li Shimin the pictures of the three crops of rice, potatoes, and corn, and told him that these were all miraculous crops that could yield fifty stones per mu, Li Er's eyes were already blood-red, and he couldn't wait to go to Southeast Asia to grab the three crops of rice, South America to grab potatoes, and the Americas to grab corn, and immediately plant them for the people of the whole Tang Dynasty, so that the people of the Tang Dynasty will never be hungry again.

This time the two sides talked very pleasantly, except for Xu Yang complaining that the two Bai Gonggongs had dislocated their arms, the atmosphere was very relaxed, Xu Yang and Li Er sat at the same table, drank the cellar together, and ate a meal rewarded by His Majesty the Emperor.

This night, Xu Yang's title was like a rocket, and he rose to the Marquis of the founding county overnight, and he ate thousands of households, from three products, to a change, and became a Hou Ye who was a serious child, rewarding one hundred taels of gold, and the fief was on the Zhongnan Mountain in the south of Chang'an City, which was enough to see His Majesty's devotion to it.

That night, Xu Yang was arranged to sleep in the Xiaoyun Hall of the East Palace, and Li Er invited him to meet with the Great Imperial Association and the civil and military officials the day after tomorrow.

Lying on the purple cloud carved windbed full of sandalwood in the Xiaoyun Palace, Xu Yang knew that Li Er, the famous emperor of the ages, would be even more intimidating in the future.

Because, he already has the determination to conquer the world.
