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 finally made it to 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 feel angry when he saw Fang Xiaoru sleeping so soundly. Damn it, I've been worrying about gains and losses all night, but you, on the other hand, slept 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 savor 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 hear 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 tea cup you put in the study at your house."
Han Du's eyes suddenly widened. He was really not afraid of thieves stealing, he was just afraid that thieves would miss him. There are only one pair of teacups in his study, which he got from Lao Zhu's study by encouraging An Qing. For this reason, Han Du was eliminated by Lao Zhu more than once or twice.
However, Han Du would definitely win this bet, even if Fang Xiaoru wanted to use his precious tea cup as a bet. Han Du nodded lightly and agreed.
Fang Xiaoru saw that Han Du agreed so happily, but he knew how much Han Du valued those two teacups. I don't want to show it to others at all, but Fang Xiaoru has seen it once. And it was also a unique time. Ever since he asked Han Du to give him one, Han Du never showed it to him again.
He had no choice but not to say anything about the treasure, and he directly blocked him with that, 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's work, there's no need to be so early.
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 men. Although those people before were also very powerful, they were thieves who stole the sacrifices of their Sun God and 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 guards need help from their tribe. They just want to see how the grown food is 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. He hesitated that Han Du and others wanted to see how the grain was dug out, so he also brought a few coolies with him, all of whom were his usual friends.
The chief's son first took Han Du to the place where sweet potatoes were grown 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 if it is beans, you can see the grain when you lift the leaves. The current situation is very different from what he imagined.
Han Du straightened up. After confirming that it was a sweet potato, Han Du's heart was completely relieved.
He smiled and said to Fang Xiaoru in a good mood: "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 confident, so why does he still think 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 brought. The two listened to the chief's son's instructions and did not waste any time. One quickly lay down on the ground and picked out the vine seedlings. The other squatted on the other side, holding a tool made of stone, and began to dig the soil.
Seeing the underground 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 there was the technology to smelt iron. , 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 I'm not surprised that they used tools made of stone to dig the soil. "
Fang Xiaoru was completely shocked when he heard this. He suddenly raised his finger 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 similar to the level of our Xia Dynasty. They should be able to cope 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 moment 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's 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 this is not the most fundamental reason."
"Oh? I'd like to hear from you, 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 he have a close relationship, Fang Xiaoru will 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. He treated Han Du with great courtesy and showed that he was taught. But if Han Du was making trouble unreasonably and deliberately belittling Confucianism, then Fang Xiaoru would have to defend his doctrine!
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 tools, we were able to completely trample all beasts, whether 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 suddenly fell into deep thought. I kept thinking the word "survival" in my heart. After a while, I had to admit that Han Du was right. No matter education, no matter reading and inheriting the legacy of our ancestors, the word "survival" cannot be closed, and it is coming even more fiercely.
If the warehouse is solid, 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 education is given, it will be in vain.
"Brother Han, I hope you can learn from me." Fang Xiaoru straightened his posture and bowed respectfully 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 the words that came out of his mouth were... Han Du quickly stepped forward and grabbed Fang Xiaoru's arm, trying to help him up, and said at the same time: "Brother Fang, what are you doing? I’m just saying it tentatively, so you can just listen to it.”
"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 bowed solemnly to Han Du again.
This time, Han Du did not take the initiative to help Fang Xiaoru up. Since others have said this, if I don't accept this courtesy from him, maybe he will continue to bow endlessly. In this case, in order to avoid everyone's trouble, Han Du reluctantly accepted it.
The key 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 Gai!
After the salute, Fang Xiaoru consciously stood half a body behind Han Du 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 his 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 up almost everything under the soil. One of them put down the stone tool in his hand, reached out and dug into the soil. His fingers dug deeply into the soil, and then he suddenly pulled up the whole thing with force. After shaking off the soil a few times, you can see the roots of the sweet potato hanging down from the gap between the man's fingers and hanging precariously on the roots.
Five or six children's fist-sized sweet potatoes, 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 is industrious and indifferent to grain and grain. He has been exposed to mathematics in the academy and his mental arithmetic ability is also among the best. He only needed to look at it and he could roughly tell that the grain in the man's hand weighed just over two kilograms. And he just dug one plant. How much land does this plant occupy? It's just one foot square.
One foot square 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. Instead, he reached out and pulled a sweet potato from the native's hand, rubbed away most of the soil, and broke it in half with force. Just take one bite of the snow-white pulp, and it is crispy in the mouth. Although there is residue, you can taste the sweetness.
Sweetness, this 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 also reached out and grabbed the other half from Han Du's hand, and took a bite as Han Du did. Even though his lips were covered with mud, he didn't care. Instead, he carefully tasted the taste of the stuff.
As soon as he tasted the taste, Fang Xiaoru's eyes lit up, "This thing is actually sweet? And 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, Things can also make people survive.”
