"The second longest river in the world is called the Amazon, located in the distant Americas, and the first is the Nile, located on the equally distant African continent!" Li Xiu said with a smile, Li Xiu also felt very satisfied with Li Chengdao's cooperation, and now he felt a little cute when he saw him. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

"Where is the Americas, and where is Africa?" Lee Seung-do asked again like a curious baby, he was full of curiosity about everything he didn't know.

"Africa is located in the southwest of us, you need to go through the Western Regions and then walk thousands of miles to reach, of course, you can also take the sea route, and it is also the hometown of Kunlunnu, as for the Americas, it is located in the far east, where there are two continents, north and south, and the Amazon River is located in the north of South America." Li Xiu patiently explained again.

"It turns out that Kunlun Nu lives in Africa, and I heard that they are all a group of uncivilized savages, and they are even in the era of Ru Mao drinking blood, I don't know if this is the case?" Li Chengdao was also interested in Li Xiu's words at this time, and asked again with great interest.

"This is not comprehensive, central and southern Africa are indeed a group of uncivilized savages, but in the north of Africa, that is, the lower reaches of the Nile, the first longest river, there is a very long ancient civilization, this ancient country is called Egypt, when our ancestors were still in the rule of the three emperors and five emperors, Egypt has established a unified state, their ruler is called Pharaoh, and they believe that as long as the body does not rot after death, it may be resurrected in the future, so during the Pharaoh's lifetime, the mausoleum will be built with the power of the whole country, The scale is extremely grand, and it looks very much like the 'gold' character of our Chinese character, so it can be called a pyramid ......"

In order to show off his knowledge, Li Xiu talked about the ancient Egyptian civilization by the way, and as a result, Li Chengdao's eyes lit up when he listened, although these histories sound like a fantasy, but Li Xiu is reasonable, definitely not like it is made up, and there are too many things that he has never heard of and never thought of, so he was fascinated by it for a while, and at the same time, his impression of Li Xiu has also changed greatly, it seems that the other party can get the attention of his aunt, and it is not unreasonable.

Princess Pingyang only knew that Li Xiu was very knowledgeable before, but she didn't expect him to know so clearly about things thousands of miles away, even if it was about the Americas, she had heard Li Xiu talk about it before, but it was the first time she had heard about Africa and Egypt, which also made her very curious, at Li Xiu's age, where did he learn these things?

finally waited for Li Xiu to finish speaking, and he felt a little dry at the moment, but when he saw Princess Pingyang's surprised expression, he couldn't help but smile with satisfaction in his heart, but at this time, Li Chengdao suddenly shouted: "Li Xijiu, what you said is really wonderful, I still have many unsolved questions to ask, I wonder if you can help me answer them?" ”

When Li Chengdao said these words, his two big eyes also flashed with a bit of unknown eagerness, which was mixed with a bit of admiration, which made people really can't bear to refuse, but Li Xiu said that these were actually for Princess Pingyang to hear, and he also wanted to accompany Pingyang for a while, and he really didn't want to waste time on this little kid, so he also showed a little hesitant expression for a while.

"Li Saijiu, Dao'er usually has a lot of schoolwork, it's rare to have something he is so interested in, why don't you help him explain it, I'll play with Qi Niang!" At this time, Princess Pingyang also helped her nephew speak, speaking of which, since she came in just now, Qi Niang has not come over, but sat there as if she was playing something, which made her very curious, you must know that Qi Niang was very sticky to her before, what happened today?

Seeing that Princess Pingyang also helped Li Chengdao intercede, Li Xiu couldn't refuse anymore, so he had to nod and agree, which also made Li Chengdao cheer happily, and pulled Li Xiu to sit down in the pavilion not far away, and then told his questions about Egypt in an ancient way, Li Xiu had to answer them one by one, and finally finished the answer, but he didn't expect Li Chengdao to start asking questions about the Americas again, and he didn't allow him to have any respite.

At the same time, Princess Pingyang also walked towards Qi Niang with curiosity, when she came in just now, Qi Niang just smiled at her and said hello, and then lay on the grass and looked at something seriously, and when Princess Pingyang approached, she found that there was a small shelf in front of Qi Niang, and there was a transparent sheet on it, and I don't know if it was made of water jade or medicinal jade? There's also a ball of velvet under the shelf, and I don't know what she's doing?

"Qi Niang, what are you doing here?" Princess Pingyang sat next to Qi Niang with her skirt and asked softly.

"Sister Xiuning, this is an experiment done by my brother, he said that only this crystal lens can ignite the velvet underneath, I don't believe it, so I have been guarding it like this." Qi Niang turned her head and said softly at this time, as if she was afraid that speaking too loudly would cause the experiment to fail.

"How is it possible to just light the velvet with this lens and still leave it untouched?" Princess Pingyang couldn't help but exclaim in surprise when she heard this.

"It's really possible, Sister Xiuning, you can put your hand under the lens and try it!" Qi Niang said and pulled Princess Pingyang's hand and put it on the light spot under the shelf, but Princess Pingyang immediately felt a little hot in her hand, and involuntarily pulled her hand back, touched the back of her hand but there was nothing, and then she put it back again puzzled, and found that there was a point of light on her hand, and where the light point shone, there was a burst of scorching heat.

"Strange, what the hell is going on?" Princess Pingyang looked at the spot of light under the lens and asked with a puzzled expression.

"Giggles, it turns out that Sister Xiuning doesn't know, but just now I heard my brother say that this crystal lens can concentrate the sunlight to a point, thus producing a very high temperature, so that the velvet can be ignited, let's wait a moment to know if this is the case!" Qi Niang didn't know when she saw Princess Pingyang, and she was also happy at the moment, as if she was happy to have one more companion.

Princess Pingyang was also aroused at this time, and stared at the point of light under the lens with Qi Niang at the moment, because Qi Niang had been waiting for a while before, so Princess Pingyang did not wait too long at this time, and soon saw that the velvet below began to emit a trace of green smoke, and then sparks began to appear, and finally it really burned.

"It's really burning, it turns out that what my brother said is true!" Seeing the burning velvet, Qi Niang couldn't help jumping up and shouting happily.

Princess Pingyang was surprised at this time to pick up the lens on the shelf and observe it carefully, but she didn't find any mystery after looking at it for a long time, but found that the middle of this lens was thick and thin, did this have anything to do with lighting velvet?

"Sister Xiuning, there are a lot of different lenses here, just now my brother taught me some other ways to play, come and take a look!" At this time, Qi Niang suddenly stood up and ran to the side and shouted, Princess Pingyang walked over curiously, but found a small open box on the ground, which contained some polished lenses.

I saw Qi Niang reach out and take the lens in Princess Pingyang's hand, and then pick out a lens from the box, and put it in front of her eyes one after the other, as a result, she immediately let out a "giggle" laugh, began to look around, and finally suddenly stopped in a certain direction and shouted happily: "Sister Xiuning, look, there are a few sparrows fighting in the tree!" ”

"Where?" Following the direction that Qi Niang was looking, Princess Pingyang also turned her head to look, but except for seeing a forest in the distance, she didn't see any sparrows at all, not to mention that even if there were sparrows, it was impossible to see them in such a dense woods.

"There really is, Sister Xiuning, look at it!" Qi Niang pulled Princess Pingyang to squat down at this time, and then put two lenses in front of her eyes, and asked her to close one eye, what Princess Pingyang didn't expect was that the scenery in the distance seemed to be pulled closer all of a sudden, and everything became clear in front of her eyes, and indeed as Qi Niang said, there were really a few sparrows fighting in the trees in the distance.

"This ...... Is this some kind of spell? When Princess Pingyang saw this magical scene, she clutched her chest and said in disbelief, apart from the legendary spells, she really couldn't think of anything that could achieve this effect?

"Giggle~, Sister Xiuning is the same as me, at first I thought my brother could spell, but then my brother told me that this is called a telescope, and as long as you fix these two lenses with a tube in the future, you can hold it to observe the situation in the distance." Qi Niang smiled again, at a young age, she just thought the telescope was very interesting, and she didn't realize its true function.

"Telescopes? Telescope! If every general could be equipped with a telescope, wouldn't it be possible to detect the enemy situation in advance? Princess Pingyang was excited at this time, she was a military general, so she was naturally the first to think of the role of telescopes in military affairs.

Thinking of the role of the telescope in the military, Princess Pingyang finally couldn't bear it anymore, and walked over quickly to confirm the role of the telescope to Li Xiu, but when she came to the pavilion, she suddenly saw Li Xiu talking about something in high spirits, and the young Li Chengdao was holding his cheeks with his hands, listening attentively with a look of intoxication, and from time to time the corners of his mouth would show a little knowing smile.

Seeing this warm scene, Princess Pingyang couldn't help but feel soft in her heart, and her steps couldn't help but slow down, she almost regarded Li Chengdao as her own biological child, and usually felt sorry for his heavy schoolwork, and now she finally had the opportunity to relax, and she couldn't bear to interrupt them.

Li Xiu was telling Li Chengdao about the Americas, and just after he finally talked about the situation in the Americas, Li Chengdao suddenly asked: "Li Xijiu, there must be people in Africa where Kunlun slaves are located, otherwise we wouldn't have so many Kunlun slaves in Datang, but have anyone been there in the Americas?"
