didn't wait for a long time, I saw Li Xiaogong and Li Chongyi coming from afar, Xia Hongsheng and the two of them sorted out their clothes, and when they got closer, Li Xiaogong saluted Li Tai and said, "Your Highness." ”

Li Tai also saluted Li Xiao at the same time: "Meet my uncle." ”

"Meet the King of Hejian." Xia Hongsheng smiled and gave a salute.

"Xiahou is polite." Li Xiaogong nodded and said with a smile.

Behind Li Xiaogong, Li Chongyi was still wearing the clothes of the military academy, and each person in the military academy was given three sets of clothes to change and wear, and they had to wash them by themselves. Li Chongyi bowed and saluted: "Students meet Master Yuanzheng!" ”

This Lilly came and went, and after a lot of tediousness, everyone finally arrived in the hall.

"Hahahaha, the dog has never been a weapon, the old man fought in the south and the north, and he had no time to clean him up, and he was a military general, rude by nature, and the dog was with me, but he was not angry, and he was doing nonsense in Chang'an City all day long, making a lot of trouble." Li Xiaogong said to Xia Hongsheng: "Since Chongyi entered the military academy, this is really like a different person, and the old man almost doesn't recognize it." Thinking about it, it must be that Xiahou has managed the school well, and the teachers have done their best, which has such a miraculous effect. The old man is here, thank you Xiahou! ”

As he spoke, Li Xiaogong got up and bowed to Xia Hongsheng.

"Don't dare!" Xia Hongsheng was not arrogant enough to let a county king salute him, so he hurriedly dodged sideways, and said: "Why should the prince do this, the prince helped me before, and I am also grateful to him, and Brother Chongyi is already familiar with me, often playing, and the brothers are commensurate, so this is the righteousness that should be done, if the prince is so polite, but it is tormented by me." ”

"Hahahaha! ......" Li Xiaogong burst out laughing. He also said: "I heard that Xiahou is with Du Xiang, Fang Xiang and others. They are all called uncles and nephews because of their friendship with juniors. Since Chongyi and Xiahou are also good friends, then you and I don't have to see each other, and we are commensurate with uncles and nephews, okay? ”

"This ...... Haha, little nephew to meet uncle! Xia Hongsheng smiled and bowed.

"Hahahaha! Good! Li Xiaogong smiled and narrowed his eyes: "Don't leave today, wait for the old man to set up a family banquet, and when the virtuous nephew gets drunk, thank the virtuous nephew for his support to Chongyi!" ”

"Uncle said this, and he saw it. They all play around together all day long, their own brothers, why be polite? Xia Hongsheng waved his hand and said with a smile: "I don't plan to leave early today, keep my belly and rub my food!" ”

The two looked at each other and smiled, Li Tai rolled his eyes beside him, and interjected: "Uncle! Qingque has been here for a long time, why does my uncle patronize and talk to him without asking Qingque? ”

Li Xiaogong laughed again when he heard this, and said, "Hahahaha." But it's my uncle's fault! But I don't know why His Highness came here today? ”

"Qingque has come to see my uncle today. There really is something! Li Tai was amazed by his acting skills, and even Xia Hongsheng was surprised by his performance.

"Oh?" Li Xiaogong was stunned for a moment and said with a smile: "Is there really something?" Your Highness, tell me about it? ”

Li Tai nodded and said, "Qingque came today to want his uncle to be a judge. ”

"Judge?" Li Xiaogong looked at Li Tai with some surprise: "But I don't know what His Highness wants me to judge?" ”

Li Tai pointed at Xia Hongsheng, and said with some anger: "He said that a boat made of steel can also float on the water without sinking to the bottom, I don't believe it, steel is so heavy, how can it float on the water?" Obviously, even a stone can't float to the surface of the water without sinking to the bottom! But he wanted to say yes! My uncle has led a water army, so I want to judge my uncle! ”

"Steel makes a ship?!" Li Xiaogong looked at Li Tai and Xia Hongsheng in surprise: "How can steel be used as a ship, then it can't sink to the bottom as soon as it hits the water?" ”

"Hehe, it's okay to make a ship out of steel. However, there are many issues that need to be solved about what kind of ships are involved. Xia Hongsheng said with a smile: "My little nephew has heard my master say before, there is a kind of ship with steel as bones, iron clothes as skin, it is as big as a kun, a boat is a city, and it can accommodate tens of thousands of people, which can be a water fortress." Although the little nephew can't make the boat that my master said, he can still make it if he makes it smaller. If my uncle and Xiao Tai don't believe it, I will lend me a few good craftsmen who build ships, and I will make a small one for you to see, so as to prove that my little nephew is not talking nonsense. ”

"This ...... It's incredible! Li Xiaogong looked at Xia Hongsheng in surprise: "The stone is so heavy, it will immediately sink to the bottom when placed in the water." Steel is heavier than stone, and it looks like a ship, so how heavy should it be? Won't it sink to the bottom? The virtuous nephew still doesn't have to waste his thoughts, the old man has been in charge of the navy for a long time, and he can ensure that this kind of ship will not work. ”

Xia Hongsheng scratched his head, now it's time to lie to them again.

So he said: "In this way, I also ask my uncle to order the family to bring a bowl of water and bring a needle." ”

"Huh?" Li Xiaogong didn't understand what Xia Hongsheng meant, but Li Tai's eyes lit up.

The small experiment of needle floating, in fact, uses the surface tension of water, which is not the same concept as a boat. However, Xia Hongsheng couldn't tell them so much, so he had to use such a small trick to trick them into believing that iron could also float to the surface.

Xia Hongsheng once used this little trick to surprise Li Tai and others who admired him, and now he has done it again in front of Li Xiaogong and Li Chongyi. At the moment when Xia Hongsheng let go of his hand, the iron needle floated quietly on the water surface of the bowl, which made Li Xiaogong and Li Chongyi gasp.

"This ...... Why, then?! Li Chongyi's arm trembled and pointed to the iron needle in the bowl, and the frightened words were not good: "This, how can this iron needle float on the water?!" This, this must be a spell! ”

"It's not a spell, it's a gewu." Xia Hongsheng smiled, pinched the iron needle, handed it to Li Chongyi, and said to Li Xiaogong: "Uncle, this is my uncle's own iron needle, and my little nephew didn't do anything." ”

Li Xiaogong was still there surprised, he didn't speak, Li Chongyi pinched the iron needle and looked at it, and then he followed Xia Hongsheng's example and put the iron needle horizontally into the water, but as soon as his hand was loosened, the iron needle immediately sank to the bottom.

"If the uncle doesn't believe it, the little nephew will show the uncle another thing, and take the trouble to get two pieces of hard papyrus." Xia Hongsheng said with a smile.

Li Xiaogong was excited, and waved his hand: "Go quickly!" ”

Without waiting for the family to run out, Li Chongyi rushed out first, and soon, he took two pieces of straw paper.

Xia Hongsheng took the straw paper and pinched it, the hardness was quite good, so he asked someone to fetch a basin of water and put it on the ground.

Xia Hongsheng laughed, raised the straw paper in his hand at Li Xiaogong and Li Chongyi, and said: "Uncle, Brother Chongyi, in your opinion, if this paper is put into the water, it will sink at that time, or will it float on the water?" (To be continued.) )
