Chen Chao led the Ministry of Foreign Affairs to the foot of Tianyuan Mountain first, rested in the new residence of the tribe, had lunch and set off again.

According to Chen Chao's plan, they began to move south. The first tribe was about a hundred kilometers away from the Tian Yuan tribe.

It takes about a day and a half to two days to walk.

It took the group nearly a day to get out of the plain at the foot of Tianyuan Mountain, but it was still far away from the destination.

This is also related to the fact that the Ministry of Foreign Affairs carries the weight forward, although the wind unicycle can be blessed by the wind from time to time, but even if the wind can help go faster, the weight is still real.

And since most of the cars are made of pottery, everyone is still relatively cautious when leaving.

Finally, before the sun went down, everyone found a cave where they could rest for a while.

Chen Chao took a look, the cave is not very big, not very small, at least seven wheelbarrows and more than enough to accommodate eleven people.

After leading everyone to push the wheelbarrow into the cave, Chen Chao asked the killer five to pick up some wood for the fire.

However, most of the temporary pickups were wet wood, but there was nothing that could be done. Fortunately, the little old man's car has some spare dry wood, and after using up part of it later, replace the wet wood that was processed today, and if there is no accident, you can continue to use it in a few days.

And as long as you use some flammable materials to raise the dry wood on the fire, and when the fire is hot, you can still use it, and it may not cost much dry wood.

Not long after the five killers picked up the wood, Qu and the others from the unicycle manufacturing department also lit the fire.

After the bonfire was raised, the whole cave quickly brightened and warmed. At this time, Chen Chao also brought the little old man back with four pots of clean snow, and by the way, he also asked the killer five to pick up eight stones of moderate size at the entrance of the cave and come back to build a simple stove.

After the snow melted, the little old man put in the air-dried jerky, and it didn't take long for the whole cave to fill the cave with a rich smell of meat.

Before coming out of the pot, the little old man carefully opened a bag of animal skin that he carried with him, and added a little salt to each pot with a clean spoon.

When the broth was ready, everyone took out their clay bowls and waited quietly for the food to be distributed.

After dinner, Chen Chao took out a piece of wood that was about to burn out, and after extinguishing it on the mountain, let it cool for a while.

And let the others take off the nests, and the skins and limbs wrapped around their feet were also untied, and carefully dried near the campfire.

After all, after a day of walking in the snow, the nest was almost soaked with snow, although there were still several layers of animal skins to protect the feet. But if you don't take it off at night, it's easy to get chilblains.

After the wood was almost cool, Chen Chao went to the little old man's exclusive cart to find a wooden board prepared before departure, and began to draw on it by the light of the fire.

The little old man with the horns of the sheep leaned forward and took a look, what is this black east and west?

The little old man asked curiously, "This is... What the? ”

Chen Chao pointed to the black line just now and said, "This is from our tribe to here, and then this is from there to the mouth of our cave, Nuo, you look at this shape in this, it doesn't look like a cave." ”

After such a long time of language learning, especially when Chen Chao still has nothing to do, he will open a little old man and Yuan Kaixiaozao to make up classes. So now the two of them can quickly understand most of the meanings expressed in Chen Chao's daily speech.

Of course, as long as it doesn't involve some new words and some words with multiple meanings, the two of them can still quickly grasp and understand what the core idea of Chen Chao's speech is.

At this moment, a member of the unicycle manufacturing department also came up, it was Li Nong, who was missing two fingers, and he was also very interested in the plank in Chen Chao's hand.

Chen Chao glanced at Li Nong, but had no intention of driving him away. Anyway, it was going to be explained to the little old man, and since he was interested, it wouldn't hurt if there was one more person to listen.

And Chen Chao was very impressed by Li Nong, mainly from his severed finger.

His fingers were frozen when he came out to look for food in the winter, and Wu Du said that he was hopeless, and the people of the tribe had no hope for him at that time, so he took a stone knife and cut off the two dead fingers, survived a spring, and gradually got better in the summer.

When Chen Chao knew about this, he sighed in his heart, 'This is a ruthless person! ’

The little old man nodded, Chen Chao looked at it, the little old man's shadow was stretched by the flickering firelight, and the horns on his head were also projected onto the cave wall, and behind him became a deformed and somewhat cute huge black shadow.

Next to the other hand sat Li Nong, his figure was also projected onto the wall by the flickering firelight, and his burly body appeared larger in the reflection of light and shadow.

The people in the cave sat together in twos and threes and talked quietly, sometimes they spread their own animal skin quilts and fell asleep, which was waiting for them to get up to keep watch at midnight and late night, so Chen Chao told them to go to bed early and nourish their spirits earlier.

Qu took another member of the killer five-person group to keep watch near the entrance of the cave in the morning and night, and also had to pay attention to the bonfire in the cave from time to time, and then whether they were on duty in the middle of the night or midnight, their duties were the same as those of Qu's group of guards on the eve of the night.

Chen Chao took his gaze back and continued to explain to the little old man, "If we record all the tribes we went to this time with a wooden plank, will the people of the tribe be able to find these places with this wooden board next time without the two of us leading?"

Or if you get lost, can this board also be used as a reference for the right direction? ”

The little old man listened to Chen Chao's words and nodded incessantly, and the little old man also recognized and agreed with his statement.

It's just that he raised another very important question, "Charcoal, planks, will fall." And, one copy. ”

Chen Chao thought for a while, and estimated that the little old man meant that charcoal paintings were easily washed away by water on wooden boards, or easily spent. And there is only one plank, what if the other people also need to know the route?

There are two main problems raised by the little old man, one is the storage of wooden records, and the other is the problem of quantity.

The first problem was easy to solve, Chen Chao picked up a relatively sharp stone from the ground, and began to dig a pit out little by little along the black line he had sketched.

The little old man quickly understood what Chen Chao meant, and he excitedly took the wood in Chen Chao's hand and started to be a happy digger.

After solving the first question, Chen Chao said with a smile, "Wu, this thing is called a map." It is to use symbols, lines, colors, text notes, etc., to show what the places we have been look like in a certain proportion.

For example, in this cave where we are temporarily resting, there is an icon representing the cave. Not only caves have icons, but also mountains, rivers, and rivers that you encounter when the time comes.

Even if there are any good things in the vicinity, such as fruit groves or something, you can write them down.

Then we went to other tribes, what this tribe looked like, how many mountains we had to go around, how many rivers we had to cross, what good things we met.

In this way, we don't have to come in person, and the rest of the tribe knows the specific situation.

And, you see, words can be used here as well. There are many things that cannot be represented in pictures, and we can express them all at once with words.

For example, if there is something in this piece that cannot be represented by drawing, can it be roughly explained in words? ”

After listening to this, the little old man silently digested it for a while before exclaiming, "Ah, then this... What is it, it works! You don't have to... We... Here it comes... Words... It's used here..."

Chen Chao thought for a while, what the little old man meant should be that this map is really useful, if you still need to trade in the future, you can let the people in the tribe take the map around, so you don't need a few of us high-level people to run around. And I didn't expect that the words I learned could still be used here!
