In the second year after the establishment of the Vine Tribe, it was the night of January 6th.
"Scratch scrape..."
In the bamboo house, Jiang Xuan found ten pieces of wood that were as tall as a person and about ten centimeters in diameter. Numbers were engraved on each piece of wood.
What he was engraving was decimal Arabic numerals, from zero to one hundred. This was a big project. He started it three days ago and didn't finish it until today.
"Finally finished!"
Jiang Xuan finished carving the last number, then put away the blunt stone knife, stood up and stretched.
Nan Xing on the side asked curiously: "Chief, what are these you carved?"
Red peony root, Uncaria spp., and Stone Loach also came over, and they were already very curious.
Jiang Xuandao: "These are called numbers, which are symbols used for counting. For example, we have ten fingers, which correspond to the most basic ten numbers from '1' to 10."
"In the past, when you counted, you counted on your fingers. If there were a little more things, it would be considered unclear, right?"
"If you learn these numbers, you won't have to count on your fingers anymore, and you can easily calculate the quantities of a lot of things."
Chi Shao's eyes lit up and she said: "Chief, I want to learn!"
As a witch, Chi Shao usually needs to know the number of people and supplies in the tribe.
But just like Jiang Xuan said, because she had never learned arithmetic, she could only point her fingers one by one.
It didn't matter in the past. After all, the Vine Tribe has a small number of people and few things. Even if you pick it up with your fingers, you can easily figure it out.
But now that the number of people in the Teng tribe is increasing, and there are more and more various things, when the red peony is counted again, it is obviously beyond its capabilities and can only make a rough estimate.
Because of this, after hearing Jiang Xuan's explanation, she was eager to learn this kind of numbers and algorithms.
Jiang Xuandao: "Actually, this kind of number is very simple and easy to remember. I have engraved all numbers from one to one hundred on the pillars. From now on, you can come and look at them several times every day, and you will learn it soon."<
/p>
"Come on, let me teach you how to identify these numbers first..."
Jiang Xuan patiently taught Chi Shao and others the ten Arabic numerals from "0" to "9" one by one. He also pointed to the numbers on the pillars and explained to them the usage of decimal numbers in detail.
Then, he folded a bunch of small sticks and taught them the simplest addition and subtraction.
After they learn addition and subtraction, let them recite the "Nine-nine Multiplication Tables" and learn multiplication and division.
Of course, this is a very long process, and Jiang Xuan also experienced the madness of being a teacher.
"Shi Loach, when you write '3', can you please stop writing it in reverse?"
"Nan Xing, how did you come to the conclusion that 7 7 = 11?"
……
Of course, there are also outstanding students, and that is Chi Shao.
Chi Shao is not only talented in painting, but also talented in arithmetic. After only two days of learning, she was able to write from one to a hundred and perform simple addition and subtraction operations.
In a happy mood, Jiang Xuan specially made several simple animal brushes using wild boar hair, fish bladder glue, and reed rods, so that Chi Shao could write on animal skin rolls more conveniently.
When Jiang Xuan finished teaching red peony root and then went to teach uncaria and stone loach, he obviously felt his blood pressure rising, and couldn't help but want to open their brains to see what was inside.
This may be the difference between a bad student and a top student.
After Chi Shao and the others learned numbers, Jiang Xuan began to promote numbers and algorithms to other tribesmen, ordering everyone to learn them.
At the beginning, the Vine tribe was naturally wailing.
Many people, if you ask them to hold a spear and fight for prey, they will not frown at you, but if you ask them to write with a small pen, they will scratch their heads and feel like they are sitting on pins and needles.
Even if the colorful pheasant's feet are stained with paint and run around on the animal skin, it will look much better than the few numbers they held back for a long time to write out.
Fortunately, they are not children, nor are they really stupid. After learning for a while, they can basically learn simple addition and subtraction.
As for the more than one hundred tourists, they have not yet truly become members of the Vine Tribe and are not qualified to learn numbers.
Jiang Xuan divided them into three groups, each group consisted of about forty people.
The first group of tourists were responsible for collecting various edible plants and digging fruit saplings near the Vine Tribe.
The second group of tourists is responsible for plowing the land with the nard, clearing wasteland, planting food and vegetables, digging drainage ditches, etc.
The third group of tourists is responsible for setting up fishing traps, making fish cages, and catching fish and shrimp.
As for the real Vine tribe members, they are mainly responsible for hunting and guarding the safety of the tribe.
Peaceful days always pass quickly, and a month flies by.
In early February, the weather gradually warmed up, and the trees on the mountains sprouted a lot of buds. There were many weeds on the ground, and small flowers of various colors bloomed, which were very beautiful.
The rain gradually increased, and in the bamboo forest behind the rattan tribe, countless bamboo shoots emerged from the ground and grew rapidly.
"Dig out the shoots that don't grow well or are in the way, leave the ones that grow well and let them grow into bamboos."
In the bamboo forest, Jiang Xuan took the bone pick and dug up the bamboo shoots that popped up on the road leading to the altar.
Behind him, there were many tourists. They looked at the altar in the distance in awe while carefully digging out the bamboo shoots that were growing crookedly in the bamboo forest or growing on the road.
Some of these bamboo shoots will be eaten immediately, and the remaining ones will be peeled off, cooked in a pottery tripod, then torn into strips, dried into dried bamboo shoots, and kept for later eating.
As for the bamboo shoots that have not been dug out, it will not take long before they grow into large bamboos that are more than ten meters high, or even twenty or thirty meters high. They can be cut down to make various tools in the future.
After digging the bamboo shoots, Jiang Xuan continued to improve the dangerous plant defense lines on the north and south sides of the tribe.
The first to be removed were the saplings of eight thunder trees.
When he was capturing the Earth Armor Beast last year, Jiang Xuan detonated a piece of Thunder Fruit. The terrifying power of the explosion still frightened him even thinking about it.
If the thunder tree is planted together with other dangerous plants, the exploding thunder fruit may destroy other plants, leaving a huge gap in the plant's defense line.
However, the bark and trunk of the thunder tree are extremely hard and can be used to make tools and weapons. If the thunder fruit is used properly, it can also be a powerful weapon.
Jiang Xuan does not intend to give up planting the thunder tree, but will just move it away from the plant defense line.
As for dangerous plants such as the biting flower and the whip tree, Jiang Xuan continued to fertilize and cultivate the soil so that they could form a plant defense line to prevent the invasion of wild beasts and foreign tribesmen.
"By the way, there are also cage vines."
Jiang Xuan was trapped by a cage vine, and he was very interested in this dangerous plant.
The vines of the cage vine are extremely tough and contain paralyzing toxins. If used properly, they are also very good things.
However, near the Vine Tribe, Jiang Xuan has only found one cage vine so far, which is the one he was trapped in. In order to save Jiang Xuan, Chi Shao chopped down the cage vine.
Jiang Xuan led two soldiers over the mountains and found the cage vine.
"Hey, he actually grows up so fast!"
When Jiang Xuan saw the cage vine again, he found that the cage vine had grown back into a vine network, lying flat on the ground as before, waiting for prey to pass above.
One of the soldiers asked: "Chief, do we want to dig it back?"
Jiang Xuan shook his head and said: "No, this cage vine has been growing for many years. There must be a lot of roots underground. It is difficult to dig out the whole plant. If there are few roots dug out, I am afraid it will wither."
"What should we do?" The two soldiers looked at each other and both had no idea.
Jiang Xuan observed the new vines of the cage vine and found that some of the vines had a small number of aerial roots, which usually draw nutrients from the soil.
"Find two pieces of wood, hold down the vines on the ground, cut back the new vines with aerial roots, and try to plant them through cuttings."
The two soldiers immediately found two thick dead trees nearby, and then they pressed against the cage vine on the ground.
The poor cage vine has never encountered such a situation. All its vines struggled and twisted desperately, trying to close, but they couldn't get up at all.
Even the vines with poisonous stings could not reach the two warriors because they were also suppressed and could not reach too far.
"Hey, are you being honest now?"
Jiang Xuan took out a sharp stone knife and cut off the still twisting cage vines with air roots. Then he wrapped a ball of moist soil around the cut and put it into the animal skin bag.
After the severed vine twisted a few times, it gradually stopped moving and looked no different from ordinary vines.
Jiang Xuan cut a total of nine vines with air roots, then tightened the mouth of the animal skin bag, and said refreshed: "Let's go back to the tribe."
The two warriors removed the dead tree holding down the cage vine, and all the vines of the cage vine immediately wrapped themselves upward, turning into a circular cage.
But because Jiang Xuan cut a lot of vines, the cage has several obvious gaps.
The poor cage vine, like a good girl who has been bullied, is crying secretly in the forest.
And Jiang Xuan, the instigator, has already led the two soldiers away.
After returning to the tribe, Jiang Xuan planted nine vines wrapped in soil at the predetermined plant defense positions.
As for whether these vines can successfully take root and grow into new cage vine plants, it all depends on luck.
February 8, noon.
"Boom!"
The sky was covered with dark clouds, and the first spring thunder of the year exploded, awakening all kinds of insects underground.
Jiang Xuan once again engraved the words "Jingzhe" on his calendar bamboo tube.
"The first thunderstorm last year was on February 5th, and this year it was on February 8th. The time is relatively close."
Jiang Xuan is quite satisfied with this result. This at least shows that the weather in this world is also regular, which is of great help to his calendar production.
Jiang Xuan believes that sooner or later, he will be able to create a calendar that truly fits this world.
