"This is the new toy that the kid made, you won't lie to him, I don't find anything interesting about these things, and this, spinning top, this is something that has been around for a long time, and it can be considered a new toy."

Li Er was depressed, looking at the two daughters holding a few pieces of broken iron, and the pieces of broken iron were still so sharp, they were not sharp enough to be used as a knife, but it was possible to hurt people, and this top, and there was a whip in each daughter's hand, which was understandable, it was a spinning top, the only difference was that this top was painted with various colors and patterns, but there were a lot of them, five per person.

"Father, you are wrong, that kid, Hehe, is the little mother's brother Heng, but I said, this time the toys are still these spinning tops, the most important thing is not the spinning top itself, but the color on the top, don't believe me give my father a spinning top you play a spinning top to see, just take this multi-color one, father, guess what color it is."

"Yes, red, no, it's green, it's not right, it's seven colors, that's seven colors." "Father, we speak with facts." Yes, this princess has also learned some of Yang Heng's mantras, and these mantras are all famous sayings of later generations.

"What's going on, it's obviously a variety of colors, how is it a color now, and it's not any color on the top, girl, did you change the top." Li Er's eyes widened, what was going on, and then he picked up the spinning top with lightning speed, only to find that it was still the seven-colored spinning top, and there were really some doorways.

"What about the rest, good girl, hurry up and beat the top to show your father." So the two princesses took turns playing a few spinning tops, and Li Er became more and more interested, what kind of phenomenon is this, but it is very mysterious.

"Come on, ah, by the way, this should call the people of that department, just call ......" After thinking about it for a long time, Li Er didn't come up with the idea that this kind of thing should be studied by the officials of that department.

"Good girl, did that kid say who should be asked to study this, and what is the reason for this?" "Father, Xiao Niang's brother Heng didn't explain it, he just said that this is a natural science, and people who are really curious need to study it, and he doesn't have that time to study." It is true that there is no time to study, and Yang Heng has too little understanding of some light and color knowledge in his previous life, so he can't say anything, maybe he can have a little understanding, but there is not much understanding, it is better not to be ugly.

"Ah, by the way, father, Xiaoniang's brother seems to say that this has something to do with the sky, do you see if it's useful." "Yes, how is it useless, come here, Xuantai History Bureau Taishi Ling will see you." This time, Li Er can be regarded as having found the department he needs to find, and these mysterious phenomena are not just the affairs of the Taishi Bureau.

"Come, good girl, tell me what's going on with this piece of broken iron." The matter of the gyroscope was explained, even after Tai Shiling came, he was also dumbfounded, what kind of phenomenon is this, he was fascinated by it, Li Er's heart was also balanced, not just confused.

Then he remembered that there was another question about the iron piece, could there be any mystery in it? "Father, this is a toy, or I'll go to a place with ice to play with you."

The ice, such a large palace, there are many places where there are ponds that have frozen, and they are all very strong.

"Father, you see, this thing is played like this, it's much more fun than that ski, and it doesn't even need to be too big." As they spoke, the two princesses began to play on the ice.

Looking at the two elves flying on the ice in front of him, (in terms of speed and movement, it is really flying) Li Er fell into thought, what kind of useful place can this game be used, but the more I think about it, the more I feel that this brain is not enough, "Naturally, Li Er at this time will not think that the brain is not enough, and he still doesn't know that the place where he thinks is the brain) It seems that since he saw that Yang Heng, he obviously felt that his thinking was a little unable to keep up, but when he got to the court, he got better again, yes, There is also a group of elites in front of me, so naturally this psychology is balanced.

Since the brain is not enough, then find someone to think about it, "Come here, the secretary of the recruitment department, and the secretary of the Ministry of Works." "Even Li Er couldn't even think about where to use this thing, but his intuition was that he directly called the Shangshu of these two ministries, what use can it be, you think about it for me, I will also embarrass you, this country can't only think about it myself, right, do you want you ministers to do.

"Your Majesty," "Your Majesty," the two ministers came to the palace in turn, and they were also annoyed, this has just gone down to the court, and there are still many official affairs to be dealt with, so the emperor summoned them, if there is nothing serious, it must be a book.

Li Eryi looked at the faces of these two people, and obviously felt unhappy, this Ming Jun is not good, if it is a faint king, then drag it out directly and cut it, you are bold and dare to show the emperor's face, but Li Er is determined to be a Ming Jun, so naturally he has to swallow his anger.

"Come on, come on, two Aiqing, I let you see something, quality, you two, float up." When he said this, it was like floating up when it was almost over.

The faces of the two ministers are even more ugly, are we here to watch the two little princesses perform on the ice, seeing how the court is tossing you, a faint king, yes, before anything, they want to be courtiers.

Maybe the two princesses heard the displeasure from their father's voice, and the performance was even harder, originally they never dared to run at a speed, but they also ran, and even occasionally played a small trick, which was put in the future generations, maybe it was a sport, that is, there were similar products used on ice and snow, and it was not very similar, but now, this is a strange thing.

"Alas, slow down, slow down, see that the little face is frozen red, stop and rest." Li Er watched the princesses perform, looked at the faces of the two ministers, and found that when they changed from dark to curious, even surprised, he immediately summoned the princesses to stop.

"Come on, quickly carry the princess to warm up." Sample, if you fight with me, I'll make you anxious. "Two Aiqing, excuse me, I originally had something to explain to you, but your black face scared me back, okay, tomorrow I am waiting for your advice, let's go back." After saying that, he turned his head and left.

"Your Majesty, Your Majesty." The two of them are in a hurry, this thing may be used in military or civilian use, especially in the ice and snow, but how can they offend His Majesty, so the black faces of the two of them also turned red.
