Even if it was a starless and moonless night sky outside, Han Du couldn't close his eyes and looked at the roof without focus.
Just lying on the bed worrying about gains and losses, Han Du managed to stay up until dawn.
Fang Xiaoru woke up from the ground next to Han Du, rolled up and rubbed his eyes, and suddenly saw Han Du's eyes as red as rabbits, and couldn't help but asked in surprise: "No way, didn't you sleep last night?"
"
Han Du couldn't help but get angry when he saw Fang Xiaoru sleeping so soundly. Damn it, I've been worrying about gains and losses all night, but you're sleeping like a pig.
So he glanced at Fang Xiaoru, sneered twice and said, "I'm so happy to be able to sleep like this."
Fang Xiaoru turned her head to taste Han Du's words, then glared back and said, "Han Du, please stop making insinuations and criticizing Huai in front of me. Do you think I can't tell that there is something in your words?"
Han Du curled his lips and said nonchalantly: "Today we are going to see where they grow food. If you can still sleep after watching it, I lose!"
Fang Xiaoru suddenly laughed in disbelief and said, "So confident? What will you do if you lose?"
Han Du nodded lightly and replied: "What do you want to do? Just tell me, what do you like about me?"
Fang Xiaoru saw that Han Du was rarely generous, so he was naturally not polite. The lion said loudly: "Just the teacup you put in your study in your house."
Han Du's eyes suddenly widened. He was really not afraid of thieves, but just worried about them. There was only one pair of teacups in his study, and they were obtained by inciting An Qing to go to Lao Zhu's study. For this reason, Han Du was not only beaten by Lao Zhu.
Zhu Mitai once or twice.
However, this time Han Du would definitely win the bet, even if Fang Xiaoru wanted to use his precious tea cup as a bet. Han Du nodded lightly and agreed.
When Fang Xiaoru saw that Han Du agreed so happily, he knew how much Han Du valued those two teacups. He was not willing to show it to others at all. That is to say, Fang Xiaoru had the opportunity to see it once. And it was the only time, ever since he opened his mouth.
After wanting Han Du to give him one, Han Du never showed it to him again.
He had no choice but to say nothing about the treasure, and directly blocked him with words, saying that he wanted to pass it on to his children and grandchildren.
But now Han Du agreed so happily, Fang Xiaoru couldn't help but be surprised, and asked with a smile: "What? Do you think you will win?"
"Of course, do you think I will lose the tea cup to you? Just dream, don't try to take advantage of my baby." Han Du responded unceremoniously to Fang Xiaoru.
"Okay." Fang Xiaoru also nodded lightly, "Then I would like to see what it is that makes you so confident."
Han Du took Fang Xiaoru out and found the chief's son.
The chief's son looked at the sun that had just emerged outside, and then looked back at Han Du. He didn't know why the chief woke up so early. Does the chief also have to work? Even if it is work, it doesn't have to be like this.
Good morning.
But there is no way, the strong should be respected. In the eyes of the chief's son, guys like Han Du who are as powerful as the Sun God's guards are the real strong. Although those people before were also very strong, they were thieves.
The thieves who sacrificed their sun god were sent by the devil.
The devil cannot defeat the Sun God, so the Sun God sends these guards to help their tribe.
Now these
The guards needed help from their tribe. They just wanted to see how the grown food was dug out of the soil. They just went a little early. What does it matter?
The chief's son only hesitated for three breaths, then smiled and nodded to Han Du, willing to take them there now. Since Han Du and others wanted to see how the food was dug out, he also took a few of his henchmen with him.
Coolies are all his daily friends.
The chief's son first took Handu to the planting place because this place was the closest.
Han Du looked at the green vines all over the ground and couldn't help but lean down in excitement. The familiar touch from his palm made Han Du inexplicably excited.
Fang Xiaoru looked at Han Du's strange behavior, held his hands in front of him, and asked lazily: "Is this the grain you are talking about? Is there nothing here except leaves?"
In Fang Xiaoru's impression, the grains are all hanging on the branches and leaves and can be seen directly. Even for beans, you can see the grains when you lift the leaves. The current situation is very different from what he imagined.
Han Du straightened up. After confirming that it was true, the stone in Han Du's heart was completely relieved.
She smiled in a good mood and said to Fang Xiaoru: "Not all food grows on the ground. For example, peanuts grow underground."
"Oh? You mean, this thing is the same as peanuts?" Fang Xiaoru became more interested.
Han Du nodded, "Absolutely."
Fang Xiaoru smiled and said: "Well, even if it really grows underground, it's not as exaggerated as you said, right? Do you really want to make a bet with me? You have to know that if you lose, your precious teacup will
But it belongs to me."
Han Du is now full of confidence. How can he still think that he will lose to Fang Xiaoru? He smiled proudly and said, "You'd better take a look first. It's not that easy to take away my teacup."
After saying that, Han Du turned towards the chief's son and made a gesture asking him to start digging.
The chief's son nodded, then turned around and chatted with the two people he had brought. The two listened to the chief's son's instructions and did not delay. One quickly lay on the ground and picked out the vine seedlings, and the other squatted down.
On the other side, holding a tool made of stone, he began to dig the soil.
Seeing the low efficiency of the two of them, Fang Xiaoru shook his head and turned to Han Du and said: "These people are really bad at farming. They are still using stones. Even if they use iron to forge a hoe, it will be worse than now."
Much neater, right?”
Han Du was not surprised. After taking a look, he raised his head and answered Fang Xiaoru with a smile: "You don't know something. Ten thousand years ago, our ancestors also used various tools made of stone, such as stone sticks, stone axes, and stone tools."
Hoes and the like. It was not until the Xia and Shang Dynasty that the technology of smelting copper ore was developed, and then copper began to be used to make various tools. Later, harder bronze was made. It was not until the Spring and Autumn Period and the Warring States Period that the technology of smelting iron was developed.
At this time, various iron tools gradually became available. Until now, we can smelt fine steel in large quantities, so there are various weapons forged from fine steel.
So it’s not surprising to me that they used tools made of stone to dig the soil.”
Fang Xiaoru was completely shocked after hearing this. Suddenly
He raised his hand and pointed at the man using stone tools on the ground and said, "You mean, their situation now is the same as ours ten thousand years ago?"
Han Du touched it twice, shook his head and said: "There is still a difference. I think their weapons are all made of copper. They may be about the same level as our Xia Dynasty. They should be able to correspond with our Xia Dynasty now."
."
"Xia Dynasty?" Fang Xiaoru was shocked, "How many years has it been since now? They haven't made any progress in all these years?"
Han Du wanted to nod directly, because that was the fact. But he felt that Fang Xiaoru might not believe him, so he thought for a while and asked instead: "Brother Fang, what do you think is the driving force for people to make progress?"
Fang Xiaoru immediately lowered his head, and after pondering for a while, he raised his head and said, "Of course it is education. Reading can help you understand things. As long as you study, you can inherit the legacy of your predecessors and make progress step by step."
Han Du nodded and said, "What you say makes sense, but that's not the most fundamental reason."
"Oh? I'd like to hear from Brother Han." Fang Xiaoru immediately bowed to Han Du seriously, and after standing up, he stared at Han Du with bright eyes. It is related to the fundamentals of Confucianism. Even if Han Du is the Marquis of Zhenhai and has won the heart of the emperor,
Even if Han Du and him were on good terms, Fang Xiaoru would argue to the death when encountering such a thing.
If what Han Du said was reasonable, then Fang Xiaoru would naturally be convinced even if he didn't say it, and would treat Han Du with great courtesy and show that he was taught. But if Han Du was making trouble unreasonably and deliberately belittling Confucianism, then Fang Xiaoru would have to defend the truth if he was sorry for him.
Got it!
Han Du smiled and said: "The reason why we descendants of China are where we are today is because the Central Plains has always been short of food and clothing. In order to survive, we have to constantly improve various smelting technologies. When we only had stone tools, we
We can only dig food from the land, but with copper weapons, we can hunt some animals to a limited extent so that we can eat some meat. With bronze weapons, we can face ferocious beasts and even hunt them
.As for the later appearance of iron weapons, we were able to completely trample all beasts, whether they were tigers or wolves, under our feet.
Therefore, survival is the first driving force for technological progress."
After listening to Han Du's words, Fang Xiaoru immediately fell into deep thought. He kept thinking about the word "survival" in his heart. After a while, he had to admit that what Han Du said was reasonable. No education, no reading, and inheriting the legacy of the ancestors can compare to
The word survival comes more violently.
If you have a solid warehouse, you will know etiquette; if you have enough food and clothing, you will know honor and disgrace. Human survival is the first priority. If survival cannot be guaranteed, then no matter what kind of education you have, it will be in vain.
"Brother Han, I hope you will be taught directly." Fang Xiaoru straightened his posture and respectfully bowed to Han Du.
Han Du grinned, his face full of contentment that Fang Xiaoru couldn't see. It felt so good to show off.
But what came out of his mouth was that Han Du quickly stepped forward and grabbed Fang Xiaoru's arm, trying to help him up. He also said: "Brother Fang, what are you doing? I'll just say this.
, just take it as a casual listen."
"No, Brother Han's words are so inspiring that Xizhi has to bow down. Xi Zhi is not worshiping Brother Han, Xi Zhi is worshiping the truth." Fang Xiaoru said with a serious look on his face and a firm tone.
After saying that, he turned towards Han Du again
Promise me solemnly.
This time, Han Du did not take the initiative to help Fang Xiaoru up. Since everyone said so, if he did not accept his courtesy, he might continue to worship him endlessly. In this case, for
In order to avoid everyone's trouble, Han Du reluctantly accepted it.
The key point is that being able to receive such a courtesy from Fang Xiaoru, a great scholar, made Han Du feel happy from the tail vertebrae to the Tianling Cap!
After saluting, Fang Xiaoru stood half a step behind Han Du consciously to show respect. He turned to the two people who were still digging on the ground and asked: "Then how come they haven't made any progress for so many years?
"
Han Du deliberately did not answer, raised his eyebrows and said to Fang Xiaoru: "Wait a moment, all your questions will be answered later."
After listening to Han Du's words, Fang Xiaoru gradually began to understand. I am afraid that the answers to all the questions are under the soil dug by those two people.
In this case, Fang Xiaoru waited quietly.
After a while, the two people on the ground finally dug out almost everything under the soil. One of them put down the stone tool in his hand, reached out and dug into the soil, dug his fingers deeply into the soil, and then suddenly used force
, he pulled the whole thing up in one go. After shaking off the soil a few times, he saw the roots hanging from the gaps between the man's fingers, hanging precariously on the roots.
Five or six children's fists as thick as one card long were hanging on the roots and shaking. Fang Xiaoru was a little dizzy and couldn't help but kneel on the ground.
He is not the kind of nerd who doesn't know how to distinguish between grain and grain. He has been exposed to mathematics in the academy and his mental arithmetic ability is also among the best. He only needs to look at it and he can roughly know that the grain in the person's hand is about two kilograms.
It looks like. And he just dug one plant. How much land does this plant occupy? It's just one foot square.
One square foot of land can produce two kilograms of grain. How much should one acre of land produce? Even if this output is cut in half, it is still a number that can scare people's courage.
It's not that Fang Xiaoru doesn't know how to calculate, but he doesn't dare to calculate at this moment, for fear that the calculated number will shatter his common sense into pieces.
"Handu, tell me, how much can this thing produce per acre of land?"
Han Du did not answer Fang Xiaoru directly, but stretched out his hand to pull one off from the aboriginal's hand, rubbed away most of the soil, and broke it into two halves. The snow-white flesh was just one bite, and it was crisp in the mouth, although there was some residue.
But you can taste the sweetness.
Sweetness is a rare good thing. Why is Daming’s sugar so expensive? It’s because there are too few naturally sweet things.
Fang Xiaoru was not in a hurry for Han Du's answer. Seeing Han Du start eating directly, he reached out and grabbed the other half from Han Du's hand, and took a bite like Han Du did. Even though his lips were covered with mud.
, he didn't care at all, but was carefully tasting the taste of this thing.
As soon as he tasted the taste, Fang Xiaoru's eyes lit up, "This thing is actually sweet? Can this thing be eaten raw?"
Han Du nodded and said with a smile: "This thing can be eaten raw, grilled, or even cooked. It is not only easy to fill up, but also rich in nutrients. Let's put it this way, even if you only eat this and nothing else,
