"Master Zhang, you should know the answer!"

At this time, a seventeen or eighteen-year-old relative came over and asked with a smile on his face.

"You know, you are?"

Zhang Heng glanced at him and found that he was not impressed, it should be the first time he saw him.

Zhao Jiang opened his mouth and introduced: "I am the eldest prince Zhao Jiang, I want to show my face in front of my father, Lord Zhang, can you tell me the answer?" ”

Hearing this, Zhang Heng also pondered, now Zhao Gou has not yet established a prince, and this Zhao Jiang, as the eldest prince, is the most likely to become a prince, based on this relationship, he also felt that it was necessary to have a good relationship with Zhao Jiang, so he leaned over and said the answer.

"Great, I remember this favor."

Zhao Jiang patted him on the shoulder, then got up and walked out.

Immediately, he also glanced at Arnu and said with a smile: "This question is too simple! ”

Arnu said expressionlessly: "Please also ask the eldest prince to signal." ”

Zhao Jiang confidently explained: "First use three catties of gourd to scoop three times to fill the seven-catty clay pot, so that there are still two catties left in the gourd, and there is only one catty in the oil tank, and then pour the seven catties of oil in the clay pot into the oil cylinder, so that the oil cylinder has a total of eight catties of oil, and finally pour two catties of oil in the gourd into the crockpot, and then use the gourd to scoop three catties of oil into it, so that it is five catties." ”

"Haha, okay."

Zhao Gou watched him answer this question perfectly, and applauded.

Seeing this, Zhao Jiang couldn't help but be overjoyed, and immediately walked down.

When Li Yuanyu knew that they had lost, the whole person also looked listless, and sat on the ground without saying a word.

Zhang Heng saw that the game was officially over, and his hanging heart was also relaxed.

Zhao Gou was also very happy now, and said to everyone: "Ladies and gentlemen, drink good wine and enjoy delicious food today." ”

"Your Majesty"

And all the people began to salute.

Zhao Jiang walked over and said to Zhang Heng with a wine glass: "Lord Zhang, if I can win this time, I have to rely on your help, Lord Zhang, and I will set up a banquet for Lord Zhang in the future to show my gratitude." ”

Zhang Heng opened his mouth and said, "Your Highness is polite"

Immediately, Zhao Jiang also drank all the wine in the cup, and then left.

After he left, Cai Jing walked over and said to Zhang Heng: "You still have less contact with this big prince, so as not to add trouble." ”

Hearing this, Zhang Heng was also very puzzled, and said, "Isn't he the eldest prince!" How can there be trouble? ”

Cai Jing opened his mouth to explain: "This eldest prince is mother was originally the queen, but later was abolished and sent to the cold palace, and His Majesty prefers the three princes, if nothing else, then the three princes will be made the crown prince." ”

"I see, what about these three princes?"

Zhang Heng asked casually.

"You'll know later, you don't want to be an enemy with him."

Cai Jing smiled, and then chatted with the other ministers and drank wine.

At this time, Arnu walked over, bowed to Zhang Heng, and then said, "Lord Zhang, I have a question that has been bothering me, I wonder if Lord Zhang can answer it for me?" ”

Zhang Heng opened his mouth and said, "May I ask?" I won't hide what I know. ”

Arnu picked up a chopstick from the table, then let go and dropped it on the ground, and then asked, "Master Zhang, do you know why these chopsticks fell to the ground?" ”

For this question, Zhang Heng reached out and rubbed his chin, he didn't expect him to ask this question, which stumped him, and explained to him that the universal shadow power is not reliable at all.

"Haha, what's so difficult about this, as the so-called people go to high places, water flows to low places, this is all common sense."

One laughed out loud, thinking that there was nothing difficult about it.

"Master Zhang, you shouldn't be as superficial as him!"

Arnu asked.

Zhang Heng nodded, he didn't expect him to be so interested in physics, so he said: "Of course, I know you want to ask why everything falls to the ground instead of flying upwards, right!" ”

Arnu opened his mouth and said, "Yes, does Master Zhang know why? ”

Zhang Heng thought about how to explain the problem of gravity to him.

After a while, he also picked up a chopstick and said to Arnoux: "The reason why the chopsticks fall to the ground is because there is an invisible force pulling them down, do you believe it?" ”

"This really surprised me, but this is the first time I've heard this answer."

Arnu was also a little surprised.

"Invisible? So why didn't I feel it? You don't know it's not! ”

The Ninth Prince, Zhao Yong, is also unruly.

Zhang Heng smiled and said, "Nine Princes, what you don't know doesn't mean that you don't. ”

Zhao Yong saw that he still dared to talk to himself, and said in a deep voice: "Then you should show this king this power?" ”

Zhang Heng didn't have the time to pay attention to him, and continued to say to Arnu: "You just assume that there is such a force, and the chopsticks will fall to the ground, but if there is no such force!" What do you think will happen to my chopsticks if I let go of my hand? ”

Arnu thought for a moment and said, "That chopstick will definitely float in the air, not fall down." ”

"Yes, but the fact is that the chopsticks will fall down, so it can be proved that this force exists."

Zhang Heng also didn't plan to dwell on this issue anymore, after all, they pay attention to seeing is believing, and he can only use the counter-proof method to prove the existence of gravity.

Arnu felt that he was right, but it would take time for such a disturbance to calm down.

However, Zhao Yong sneered and said, "If there is really this force, then why don't I feel it at all?" ”

"Because this is an invisible force, like a magnet, some are close to bounce off, and some can be attracted, this is also an invisible force, you can't feel it and say it doesn't exist!"

"This...."

Zhao Yong was a little unable to refute this, after all, he had seen magnets.

Arnu continued: "Are these two forces the same? ”

Zhang Heng shook his head and said, "It's different, these two forces are not the same type. ”

At this time, many people also gathered around, and they all listened with relish.

One person opened his mouth and asked, "Lord Zhang, did you say that there is really a Chang'e on the moon?" ”

Zhang Heng shook his head and said with a smile: "No, there is actually nothing on the moon, it is barren." ”

But as soon as the words fell, Zhao Yong's yin and yang strange voice also sounded: "Nothing? Have you been? ”

"I haven't been there, but one day I'll prove it so you can see it with your own eyes."

Zhang Heng was confident that as long as the glass was developed, he might be able to get an astronomical telescope.

"Who doesn't say big words, how long will it be, a month, a year, or a lifetime?"

Zhao Yong also began to sneer.

Zhang Heng said with a look of indifference: "Don't worry, when I let you see it with your own eyes, you will know that what I said is right." ”

"Then I'll wait, when the time comes, if you really let us see the moon up, I will recognize you as a big brother."

Zhao Yong also replied angrily.
