The Ross tribe has never been able to get any excellent writing materials. Some intellectuals of the tribe have to engrave on the wooden boards to record some things.

For the most ordinary families, they don't need to use lettering to record important things.

Lurik holds a small carving knife of Tiejian in his hand, which is made of wrought iron, which shows the quenching and hardening. Facing a large wooden board with a rough surface, he couldn't help wondering whether even such a board could describe his knowledge well?

"What do you plan to do? If you plan to engrave, you can give me the work." Cravason kindly suggested.

"Help me engrave? I have to make some marks first, then you help me go deeper, and finally apply a little ink."

"Do you insist on doing it tonight? Maybe you can wait until tomorrow to continue."

Cravason doubted the child's energy very much, his own situation was a bit bad, and a yawn showed his fatigue.

Rurik shook his head: "It's like a piece of red-hot iron. We must strike the iron while it is hot. I have nothing to do except sleep. I will be tired tonight. I will try my best to get the Odin I know. Mark the creations of you."

Leurik's decision was of course welcomed by the two blacksmiths, and Kravasson did not complain any more.

"You just continue to do it, we will accompany you, if you are hungry, say a word. I just hope you be careful not to be cut by the knife."

"Don't worry, make sure the oil lamp is on and the stove is burning."

Let's talk, Rlik sat cross-legged, and the big plank was placed on his lap. He began to use the tip of the knife with gentle force to make extremely long marks on the plank.

At first, Clavassen didn't care, and soon he understood that Rurik was making a grid.

Lurik's intention is actually very simple, that is to use his own memory to reproduce the periodic table as much as possible in the ninth century AD.

Anyway, the "Periodic Table of Elements" really belongs to the excessively advanced knowledge. They are in the Ross tribe, who has not yet shaken off the ignorance. Can they have any deep understanding?

How can it be!

is a student who is a thousand years later. It was also about the age of fourteen that he came into contact with the "Periodic Table of Elements". Wanting to have a preliminary understanding of the meaning of it, the student is almost eighteen.

If this is true for the students after a thousand years, the illiterate people of this time and space cannot indoctrinate them too much, otherwise it will be counterproductive.

Lurik drew a large number of grids, it has eighteen grids from left to right.

At the top corner of the grid, he used the tip of a knife to mark out the word "H", and at the bottom, he spelled out the word "atom" in the Luen alphabet. The expression of the first grid is really concise and concise. The element marked "H" is the smallest survivor. He then marked the number 1 on the right side of "H" with Rune's text, which means that it has only one "atom".

There are clear marks on the oak board. When he completed a grid, Clavason and Kawei were still completely puzzled. This puzzlement went to the back grid again.

For example, the second grid scribed by Rurik is on the far right of the board!

Lurik marked it with "He", which has no other meaning, the element is "helium". Only due to the knowledge level of ancient people, no one understood that there were many traces of inert gas in the air, and they were even unable to separate them.

In fact, the real scientific development context, the discovery of helium is quite legendary, and the time when it was discovered was also the industrial age.

Lurik did not have any annotations on the element 2 and only gave it a number of "No. 2" in Luenwen. That's it.

No. 3 to No. 5, Rurik used Roman letters to mark the names of these elements. For these scientific records, the Luen script is not as spreading and popular as the Roman letters.

In fact, Rurik wanted to make some comments on the boron of "No. 5", after all, the boron element has a very good use in industrial manufacturing. After much deliberation, he had to forget, he estimated that Kravasson would not be able to easily find boron mines in the mountains. Rurik knows that he is better at doing things related to machinery, and that knowledge in other aspects is only the basic level of ordinary college students after a thousand years.

Of course, more than a thousand years later, the knowledge of any junior high school student will completely surpass the so-called wise man in Western Europe in the ninth century.

Things have reached element 6 and everything has changed.

The two blacksmiths have seen this, and finally look forward to coming to Rurik with a new comment based on No. 6.

The comment is very simple. The so-called "carbon, forms a piece of charcoal", the comments are all in Luen.

Regarding the explanation of the carbon element, Lurik used an analogy before and made a gesture with a mine and charcoal, barely making the two blacksmiths understand that there is such a "basic element".

No. 7 element, Rurik portrays an H according to the theory, and he thought a little about the label, writing "the ordinary breath that can be breathed."

"What is this breath? There is no smell?" Kravasson's sudden words really frightened Rurik, and the blade almost pierced his hand.

"Yes, it just doesn't have any smell. You and I have it in every breath. It is not very important to us, but it is more important to those trees. Blacksmith, don't speak loudly anymore, I'm afraid I will get hurt. "

Klavason nodded faintly: "You go on, I'm quiet."

No. 8 element, is annotated as "the breath of life."

The two after are not marked.

When it came to the 11th element, which is sodium, Rurik hesitated for a while and simply labeled it as "half salt."

At this point, it was impossible for Kravasson to hold his mouth. In order to prevent the child from being frightened, he endured the shock of his surprise and suddenly asked: "Could it be that the salt we eat is actually a mixture of two elements?"

"Huh? You understand? I thought I had to spend more time talking with you." Rurik sat upright, admiring the old guy's logical analysis ability.

"My son and I understand. Since you just explained all the constituent elements of minerals, how to get rid of the useless and leave them useful, or to mix different elements into the most useful tools. From the beginning, I am very willing to believe in the world. Everything is made up of a mixture of many elements. Could it be that salt...it..." Kravasson paused, "Where is the other half?"

Lurik lit the grid with the tip of his knife, and muttered the number in his mouth until he reached the 17th chlorine.

"It is it, No. 17, it is the other half of the salt. They are like a couple, holding hands with each other and becoming the smallest salt."

"Ah! It turns out to be like this~" Clavasson looked at his son Kawei, "Do you believe it?"

"Is there anything more logical than this?" Kawei said seriously, "Now I believe what Rurik says, this is worthy of belief. I don't dare to doubt Odin's wisdom stupidly."

At this moment, Rurik is really not what to say about them, maybe they are very good students, but they lack the spirit of independent thinking.

When it comes to aluminum No. 13, the ancients did not have the ability to make aluminum. Thinking of the description that the blacksmith might understand, he marked "green for emeralds". He made such a mark and couldn't help but admire his wit secretly. All kinds of silicate gemstones, their beautiful colors come from a small amount of rare metals.

The two blacksmiths couldn't understand the strange vessel like aluminum pot, they at least knew the colorful gems.

The silicon of No.14 is the easiest to annotate, and it is also the easiest for the blacksmith to understand. Rurik simply made two comments, one is "slag" and the other is "transparent sand". Since silicon is the main component of slag, it is very easy for blacksmiths to understand it.~~1~.~~1z.c

For this reason, Rurik has to say one more thing: "This substance is very important. Odin created the entire ground based on it, so holding a handful of soil, the most of which is it."

The heads of the two blacksmiths are like the hands of the lucky cat, nodding their heads in affirmation.

No. 15 phosphorus, it needs to be annotated. It can not be explained that it is the cause of the wildfire, so that it has a terrifying meaning. Rurik thought for a while, and simply marked "part of the tooth". Since they can already understand that everything is a mixture of multiple elements, the same is true for teeth.

No. 16 sulfur is the simplest label, because there are words describing sulfur in Gnostic language.

"Ah, that kind of yellow-white stone that can give off a foul smell?" Kawei couldn't help being excited this time.

Lurik did not hesitate: "That's it, it mixes with the breath of life and it becomes a terrible stench. And you, Kawei, why the fart that you eaten badly smells is because of it."

The vulgar language suddenly made the two blacksmiths laugh and calm down, and all they were left with was surprise. Kawei really wants to ask: "I've never been stupid enough to go back and chew on that yellow smelly stone. Why does my fart stink? Did I sleepwalk and chew on it?"

"Of course not." Rurik might as well explain more, "It has mixed into the ground, the onion absorbs part of it, and you eat the onion into your stomach. Don't worry, it is not harmful, and there are even some benefits."

"What good is the smell?" Kawei looked puzzled.

"I think right now, I should ask the priest to add a little sulphur powder when making soap. This way the soap will turn yellow and white, and it will have some smell. But in this way, the smallest lice and fleas will also be killed. It works better than your current soap."

Now that soap is mentioned, Kawei said excitedly: "Rurik, according to Odin's wisdom, soap is also a mixture of many elements, right?"

"Of course, don't ask more."

As Lurik marked the chlorine "the other half of the salt" and the argon mark blank, the knife immediately completed the potassium mark, writing straightforwardly "the key to soap".

"Kawei, do you want to get more knowledge about soap? Now I tell you. Look at this element No. 19, it is actually the ashes after charcoal is burned out. Those ashes are actually the key to making soap, and they can also make big The tree grows very lush. Do you understand?"

The card bit nodded vigorously, "I probably understand."

"I hope you can understand, now look at No. 20." Rurik quickly marked out, except for the Roman alphabet of Ca, the most critical mark surprised the two blacksmiths.

Kawei asked with trembling teeth: "You...you mean. That lime is actually it? And our bones, is it also?"

"Yes, this is the truth. It is integrated into the earth. As long as we eat wheat and meat, especially milk, it enters our body and forms our bones. If we eat enough, the bones will be particularly hard. Those poor people who broke their arms as soon as they fell, I think you can understand why."

"I understand, maybe for... for my bones to be harder, I should go to the mountains to find lime, and I will take a bite."

"You're so stupid!" Clavasson slapped his son's brain with excitement, "Rurik said, don't let you chew on the smelly stones, and you shouldn't chew on the white stones. You count right. Right, Rurik?"

Lurik can only explain with a smile; "Yes, you can't eat it."

Lurik is a person who can recite the periodic table back many places. This kind of thing is not too difficult as long as you practice more. Rurik vaguely remembered a lot, but gradually his mind must become a little uncomfortable.

He continued to write down the number.

Because of this time and space, people cannot understand many metal elements, and it is also difficult to prepare them. The names of the Roman alphabets left by Lilique are left blank.

Until the 26th iron, it was clearly marked again, and the marking was simpler. It was a word "svard", and the vocabulary was spelled out in five Luen letters~www.mtlnovel.com~Any blacksmith would understand that it constitutes the iron sword. element.

He would like to say something in particular: "You will feel that most things in the world are composed of many elements. Your ordinary iron sword is not like this, it is pure. But pure things are often soft."

Talking, Rurik marked the cobalt "the color of sapphire", and the nickel was blank.

The very crucial number 29 copper, Rurik wrote its name in Gnostic directly. After all, copper coins are used more frequently than silver coins in daily life. The so-called copper coin, which is a Roman copper coin, is basically a piece of pure copper.

"You all know that simple copper is very soft, and tin and lead can become very hard. Now you should understand that tin and lead are also elements."

Cravason nodded vigorously: "We can understand that tin is very soft, but lead is very heavy. They have metallic luster, maybe they are indeed similar."

"Your guess is very correct." Rurik motioned for the two to move their heads.

The only two of them, Rurik, marked the word "silver coin" in the grid directly below the copper. The box directly below the "silver coin" is marked with the word "gold coin".

Lurik completes the labeling, also based on the grid number. First release https://https://

Because the periodic table is based on the number of protons and the number of extranuclear electrons as one of the important references, the entire table is compiled. It is not difficult to assign correct numbers to gold and silver.

was marked like this, the whole room was so quiet that only the crackling of charcoal in the stove...
