Chapter 70 Lectures

Then raise a piece of hand from below.

Su Shi was a little confused about the situation, and Su You reminded on the side: "If someone wants to ask a question in class, they must first raise their hand, and whoever Mr. asks to speak, who can speak." ”

Su Shi nodded and nodded to Su Xiaomei with a smile.

Su Xiaomei stood up and said: "Sir, we have learned 'Jin Sheng Lishui, Jade out of Kungang', Brother Xiaoyou said that Lishui is the Jinsha River, and it also flows through our Jiamei." Gold can be found in the sand in the water there. ”

"Brother Xiaoyou also said that the gold of Lishui is not only gold, but also copper, iron, and many metals, and under our feet is a land rich in mineral deposits. It was because of this sentence that he deduced this situation and taught us to dig out iron sand by the glass river, and we can also dig for sand gold. ”

Su Shi was very curious: "Really? Show me! ”

Su You coughed and said in a low voice, "Sir, it's still class time." ”

Su Shi smiled embarrassedly: "Okay, then let's talk about the next two sentences, 'Sword Number Juque', which means that there is a famous sword, which is the most precious in the world, called 'Juque'." According to legend, it was made by Ou Yezi, a famous master in the Spring and Autumn Period. ”

"It is said that at that time, 'the mountain of red pansy broke out of tin, the stream of Ruoye dried up and came out of copper, the rain master swept and sprinkled, the thunder gong drummed, the dragon held the furnace, and the emperor of heaven loaded charcoal; If you look at it too much, the heavenly spirit will go down. ”

"Ouyee is because of the spirit of heaven, and he knows his tricks, and makes it the third major punishment and the second small punishment; One is called Zhanlu, the second is called Chunjun, the third is called victory and evil, the fourth is called fish intestines, and the fifth is called Juque'. ”

"These five swords, three long and two short, are the origin of the idiom we commonly use."

"Legend has it that when the giant sword was first formed, the king of Yue wore it and sat on the terrace, and suddenly saw a carriage in the palace out of control, running rampant, and frightened the white deer in the palace."

So King Yue pulled out the sword that Ou Zhizi had just forged, pointed it at the rampage, and ordered the warriors to come forward to stop it.

However, just as he drew his sword and pointed at it, the sword qi of the sword in his hand cut the carriage into two sections. So the king of Yue ordered someone to take a large iron pot, and with a stab of this sword, the iron pot was pierced with a big hole in the bowl, effortlessly, as easily as cutting rice cakes. ”

The king of Yue named this sword Juque. The so-called 'wear the copper kettle, the iron is sharpened, and the Xu Zhong is as decisive as rice, so it is called Juque'. ”

"Rice is rice cake, que, is a big gap, and later extended to the meaning of a big lack and a big mistake. Therefore, Juque is the meaning of a big mouth. ”

After speaking, he raised the whip: "I have a sword named Dakouzi!" ”

The children all laughed, and then quite a few raised their hands.

Su Shi nodded, and the kid stood up and said: "Brother Zizhan, copper-tin alloy, what you get is bronze, limited by the material, it is impossible to be harder than steel, it can only be said that the copper kettle at that time, the quality of iron sharpening is too poor!" ”

Su You hurriedly interrupted: "We are now in a text class, and these should be listened to as beautiful legends, or rather, they are a kind of pursuit and deification of the sharp and tenacious divine soldiers of the ancients." ”

"It's easy to use the blades we found in the iron sand to pass through the thin copper pot and cut through the bamboo tube filled with the coarse iron sand. Belch...... Zizhan you continue. ”

Su Shi said: "'The pearl is called the luminous light', which is about the pearl of the Marquis of Sui. Legend has it that the Marquis of Sui traveled, saw the big snake was injured and interrupted, suspected of its supernatural spirit, so that people sealed it with medicine, the snake was able to walk, because of the name of the 'broken snake hill'. ”

"More than a year, the snake title pearl to repay it. The pearl is inch, pure white, and the night is bright, such as the light of the moon, can be candle room, so it is called 'Sui Hou Zhu'. It is also called 'Spirit Snake Bead', also known as 'Bright Moon Bead'. This record is from "Sou Shen Ji". ”

"This bead and He's Bi are known as the two treasures of the Spring and Autumn Period, and then the princes fought for it, and finally it was owned by the Chu State. When Qin destroyed the Six Kingdoms, it was returned to the First Emperor, and the First Emperor ordered the engraved and Shibi to be the national seal, and then the story was extended to the Three Kingdoms. And Sui Zhu, there is no record, it is estimated that he was buried with him. ”

"Regarding the pearl of lumine, there have been a few pieces later, Zhang Heng's "Xijing Fu" cloud: 'The night light of the flowing hanging li, embellished with the bead as a candle', indicating that there is also a bead called hanging li, which has the same nature as the Sui pearl."

Then someone raised his hand again, Su Shi nodded at Zhang Qi, but Zhang Qi turned his head and said, "Little master, do you know what it is?" ”

Su You said with a smile: "The world is so big, there are no surprises, things that can shine, such as dry bones, such as fireflies, and some mushrooms, all have this phenomenon, in fact, I don't think it's very unusual." ”

"This thing only has appreciative value, but the mineral material is rare. Polished into a bead, there is no technical difficulty, it does not reflect the real strength and technical reserves of a country, nor can it bring any benefits to the people. ”

"In my heart, it is not as good as the fish that the third brother catches every day, the pottery that the seventh brother burns every day, and even the little kimchi that the little sister makes every day, it is better than it."

The children laughed again.

Su You said: "Therefore, I said that the science and engineering we are studying now can help the Great Song Dynasty to create more useful things in the future, build roads and bridges, strengthen cities, light boats and vehicles, and expand products." This is the pearl of Sui Hou and the bi of the clan that everyone should master. ”

A group of babies applauded warmly, and even Su Shi nodded again and again.

Next is the science and engineering class, today it is still the basics, the consolidation of addition and subtraction, plus the introduction to multiplication.

Then I wrote the ninety-nine multiplication table on the other side of the blackboard.

After the lecture, Su You said: "Today, Brother Zizhan not only explained the text to us, but also told two small stories related to words, which are much better than me. ”

Su Shi was startled, but the children applauded warmly again, the fat brother's text course is as interesting as the little master's science and engineering course!

Su Shi couldn't help but smile bitterly: "Mingrun, are you pulling me into the pit......"

Su You said with a smile: "Teaching is mutually beneficial, I teach liberal arts, but I am too far behind you." If you're tired, then pull the child on and the two of you for a day. ”

Su Shi said: "I'm afraid that he will scare the children, and he will have a face all day long...... Forget it, if you can manage my dinner and ensure that it is no worse than the bean curd rice cage, then I will come over. ”

Su You laughed: "Zizhan, you are really a foodie!" ”

Su Shi said with a smile: "What a foodie, you have to be Mingrun, which can be called a miracle that can turn decay into magic." By the way, what's going on with those symbols you just used for calculations? I think they calculate so fast......"

Su You said: "It is easy to write, it is written in one stroke, it saves time, and I borrowed it from Sanskrit." ”

Su Shi shook his head: "Your Sanskrit one, it's not right." ”

Su You was already immune to Su Shi's erudition, and said: "In Sanskrit, that's for the convenience of writing, the first and second Sanskrit are too close, so I changed it, if the text can't be changed, we are still painting the big seal stone drum." ”

Su Shi said: "It seems to be right too...... Little sister, where are you going? Come here, take me to see the sand gold you panned, and Brother Zizhan will check it for you to see if it's true! ”

Su Shi has a wide range of hobbies, and he watched Li Xuanzhu watch the iron sand for an afternoon, and saw with his own eyes that he scooped out a grain of sand gold the size of a mung bean, so he was satisfied.

Until the cloud board rings, everyone returns to the dinner table together.

Now the land temple, there are many bean flowers, many fish, and today Su oil will make tofu roasted fish.

Even if the soy sauce hasn't come out yet, Su Shi has already eaten it with praise.

Looking at the thriving land temple: "Mingrun, this is a small paradise." ”

Su You thought about his future fate, and couldn't help but say, "Zizhan, since you like food so much, why don't you also learn to cook with me." ”

Su Shi categorically refused: "No, I'm obsessed with a thing, it will take a long time, I won't give up until I make a name, not now, I have to go to Qingshen to study after the New Year, and then I have to take the exam, and there is not enough time." ”

The exam in the Song Dynasty was very painful, and the third-level exam of the Xie Provincial Palace had to be passed at one time to be considered successful, otherwise it would have to start again from the first step three years later.

Su You bumped into Su Shi: "I'm afraid there is Yan Ruyu in the book, right?" ”

Su Shi's face flushed all of a sudden: "Uncle Xiao, you are really a human ......."

Oh, this is the acquiescence, Su You suddenly thought of another question: "Wait, then I'll pull you to teach, will Cousin Mingyun scold?" ”

Su Shi said: "My father never cared about us, besides, he himself played until twenty-seven before he began to impact the science field, what qualifications do you have to say about me?" ”

Su You rolled his eyes, there is a kind of thing you say to Cousin Mingyun face to face!
