Rainy days are a common holiday for all animals, which also explains why many people feel particularly peaceful when they hear the sound of rain.

Our ancestors probably rested on rainy days.

Rainy days = rest days, which may be common to humans and animals.

"It's a pity that I have to work hard for food on rainy days, and the iron bacteria behind me are so heavy that it feels like I'm carrying a large iron ingot." Bifang started panting after walking for a while.

If it weren't for the raincoat, my shoulders would have blisters from the canes.

[It’s a pity, I have to go to work on rainy days]

[What a pity, I really have to do my homework on rainy days]

[What a pity, I still have to order takeout on a rainy day]

【It’s raining over there?】

【Yes, dog head body protector】

"The ground was not dry yet, but now it is even more humid. I have to wrap it with a layer of leaf bark when I go back."

Bifang lifted a foot of mud, and every step felt like stepping in a swamp. From time to time, strange insects crawled out from the ground.

The edible items were picked up, washed in clean water, and thrown into the backpack.

If you can't eat it, throw it back into the mire and watch its tail sway outside the mud.

Bits and pieces, but barely enough for a meal.

Eat a feast of bugs today!

"In the rainforest, if you are familiar with animals and plants and can resist nausea, food is actually not difficult to find."

Bi Fang felt like an old farmer planting rice in a paddy field, with the mud at his feet and the wheat seedlings in his hands.

"The white-limbed bison is probably still on its way now. I don't know if it has gone to its salt mine base. I have been waiting for it for three days. I feel uncomfortable without eating salt for a week. If I don't supplement the salt, I will

I would like to call it the strongest bison!"

[White-limbed bison: Thank you Carl, this is the honor of my life]

【What is Carl?】

【Our God is willing to call you the strongest!】

[White-limbed bison: There is a human over there who has been following me for three days, and now I’m so scared]

[Scared to the point of reading the Wildlife Protection Law all night long]

noon.

Bi Fang wanders around like a ghost, looking for anything he can eat. When he encounters a hole, he will dig in. When he sees a fruit, he will go up and pick it.

"For small mammals, they are not strong enough to withstand heavy rains. Foxes, mice, rabbits and other small mammals generally have their own nests."

"Many mice that can dig holes, such as rabbits and mice, will hide in their holes when it rains heavily. Their holes are built on relatively high ground and are not easily flooded."

"But there are always exceptions. Although squirrels build their nests in dry tree holes, on rainy days they will use their fluffy tails as umbrellas and brave the rain. Therefore, we may not really be able to get anything. Hopefully,

We could have better luck."

The little squirrel is much braver than other animals in the heavy rain.

Some seemingly weak animals have unexpected adaptability to heavy rain.

Bifang, who was dressed in green leaves, climbed up a big tree, stretched out the branches and poked. After a while, a big furry squirrel suddenly jumped out. Just as he was about to escape, he was pinched by a big hand in the air.

Fortunately, Bifang was kind and did not let it spend too long in fear. With a click, the spine broke, allowing the young squirrel to see the nut paradise early.

"Hey, it seems we are lucky, we have lunch."

This squirrel was unexpectedly big. Bifang couldn't even hold it in one hand. It weighed almost a pound and was extremely fat.

Very rare.

"Autumn hasn't even arrived yet, and you've gained so much weight. It seems like you're living a good life." Bi Fang wiped the squirrel in front of him, stuffed it into his bag, and continued to dig out, "I don't know if I'm so fat.

Are there any nuts left for us? Nuts are good things. They are the essence of plants, rich in protein, a lot of oils and vitamins."

After digging for a long time, branches and dead leaves were thrown to the ground, as well as some broken fruit shells.

"We're not very lucky. It's not autumn yet, so the squirrels haven't hoarded much food." Bi Fang clapped his hands, climbed down the tree, took off his hat and shook off the rainwater.

"The rain seems to have stopped?"

Bi Fang was surprised to find that there were no raindrops falling on his head. He raised his head and saw that the frequency of water drops falling in the forest was slower than in the morning.

After waiting for a while, the raindrops fell less frequently.

"It really stopped." Bi Fang was a little surprised.

The rain lasted for more than two days and finally stopped.

"Hurry, hurry, we're on the road." He quickly picked up the bark box on the ground and continued to track the white-legged bison.

"Although it had just rained, we did not think of chasing after several days like the first time. The remaining traces on the ground are still very obvious. As long as, wait, this is..."

Bi Fang suddenly stopped the car and looked at the hill in front of him and the huge dark cave under the hill in surprise.

"Cave?"

He lowered his head suddenly and looked at the cow hoof prints that went in and out of the ground. In front of the dark cave, there was almost a smooth road. Except for the stubborn weeds, there were obviously many fewer bushes, indicating that animals often passed by on this road, and animals

This phenomenon can only occur if the body size is not small.

Looking at the cow's hoof prints, it's obvious that the white-limbed bison went in and came out again!

Why did a bison suddenly enter the cave?

Animals are not as curious as humans, especially when it comes to dark environments.

Bi Fang's heart beat violently, and he suddenly realized that what he had been looking for might be right in front of him!

Many viewers with keen minds also noticed this. After searching for three days, they finally got the result?

[Could it be that the thing in front is the salt mine? 】

[It’s such a big hole, no wonder a white-legged bison can get in.]

【But, but...】

Some of the audience didn't know what to say...

Bi Fang was even more upset, with rare emotional ups and downs.

The total distance from the cave to his single-slope shelter is... less than three hundred meters...

Three hundred meters!

Not even half a kilometer!

"I slept all night last night, and looked for food all morning today, but I didn't even think of going a little further to take a look!" Bi Fang held his head, feeling for the first time what fate can do to people.

If he had chased a little further while wearing a raincoat the day before yesterday, he might have taken the salt and returned to the shelter long ago. How could he have waited until now, waited until now!!!

Bi Fang felt a little dizzy and wanted to vomit.

"Anyway, we should have found the salt mine now, which is a good thing." Bifang patted his forehead and felt a little hot.

This is a good thing, a good thing.

I kept thinking to myself that this was a good thing. After a while, I finally calmed down.

"In ancient times, both at home and abroad, the control of salt was at the military level. Many civilians who did not eat salt would even boil salt from the walls of pig pens or even the walls of toilets."

"They will break the soil into pieces, then soak it. After a few days, they will filter out the brine and boil it in a clay pot. After the water is dried, the remaining crystals are nitrate salt."

"This kind of salt tastes very bitter, and if you eat too much, you will be poisoned. The only thing you can do is to save yourself from death because you can't eat salt."

"Some people even mix different flavors of soil together and find that the salt produced in this way is of better quality..."

Bi Fang has not even mentioned the more disgusting "urine salt" and "feces salt", which are true portrayals of the ancient bottom.

【Ah, is this like this?】

【Is salt so difficult to get?】

How much does a bag of salt cost in the supermarket?

Many people have never bought this kind of thing, but those who are familiar with it know that it costs about one yuan.

You can buy a bag of salt for one piece. If you save a little, you can eat it for nearly two months.

But outside of industrial society, salt is life.

If you understand this, you will know that it is difficult to obtain salt in the inland and wild survival.

"Actually, I have thought about other ways to find salt before. Mineral salt can not only be found by following animals, but also sometimes deposited on many rock walls with water seepage, or on banks where the water flow is not fast."

"Salt can even be found in some trees, such as the summer cypress palm. After its roots are boiled and dried, black crystals will precipitate, which are also salts, but I haven't found what you can see."

Thinking of this, Bi Fang felt unlucky and searched the lower reaches of the two rivers, but couldn't find any mineral salt.

After it rained, the chances of finding even smaller ones were smaller. Even if there was any precipitation, it was basically washed away by the rain.
