Tanning leather in the wild?

The first thought that many viewers heard was disbelief, but Bi Fang seemed confident.

"In fact, the so-called tanning, the essence is to turn the raw hide into leather, so that the skin collagen polypeptide chain between the formation of cross-linked bonds, increase the stability of the collagen structure, improve the ability of the animal skin to resist various environments, the key to this process is the tanning agent!"

[Yes, isn't tanning agent a chemical?] How is this going to work? 】

[That is, it is difficult for a good woman to cook without rice! 】

"Who says tanning agents have to be chemicals with complex processes?" Bi Fang shook his head, not agreeing with the statement of the sailors.

"On the contrary, the cerebral spinal cord can be used directly as a tanning agent! The cerebral spinal cord prevents the fibers from regrouping to form hides. As long as the fibers remain stretched and separated after drying, they are no longer rawhides. ”

"Does anyone remember? The rabbit I roasted yesterday didn't have a brain pulp. ”

[Ah, this, how can I remember this......]

[I thought it was Fang Shen who simply didn't like to eat rabbit brains, and was curious, such a delicious thing......]

[666, I learned it again, I used to think that I learned mathematics, physics and chemistry well, and I was not afraid of bragging when I traveled all over the world, but today I saw Fang Shen and knew that I was careless! 】

[I was so scared that I hurriedly finished my chemistry homework.] 】

"Actually, it's not just the brain marrow, the egg yolk can also be used, but whatever you use, just make sure that the whole hide fully absorbs the mixture."

Bi Fang explained as he restored the surrounding environment to avoid forest fires and leave traces.

Then he took his equipment and walked towards the place where the meat was hung yesterday, and he put his brain in it.

But as soon as he walked a few dozen meters, the audience found that Bi Fang's body suddenly stiffened, and then reflexively pulled out the short spear behind his back!

The audience was immediately taken aback by Bi Fang's reaction and didn't know what was going on.

At this time, the drone also chased up from behind and photographed the scene in front of Bi Fang.

Someone just saw that just a few meters away, there was a huge footprint!

There are beasts, and they are not small!

[, what kind of footprints are they, so big? 】

[It's a bear, right?] 】

[It's huge! 】

The water friends who reacted finally knew why Bi Fang had that reaction just now.

When I woke up early in the morning and looked at it, I found that there was a beast passing not far from where I was sleeping.

"That's right, it's a black bear!"

Bi Fang's expression was solemn, he really didn't expect that there would be a great horror passing by when he was asleep.

He looked around, and after confirming that it was safe, he cautiously approached, pointing to the footprints and said.

"From the shape, we can easily see that this is a bear's footprint, because the black bear's front and rear limbs have 5 toes, the toe ends have sharp claws, which cannot be retracted, and the plantar pads of the front and rear feet are wide and fat, and the characteristics are very obvious, and this footprint is very fresh, even just stepped on, so I was so nervous just now."

Bi Fang carefully looked at the size of the footprints, stretched out his hand to compare them, and couldn't help exclaiming: "This guy is really big, the length of the footprints alone is more than 20 centimeters, I estimate that it is an adult black male bear, weighing at least more than 200 kilograms, almost surpassing three me!" ”

Listening to Bi Fang's description, the sailors were all taken aback.

Two hundred kilograms of black bear, how big is that?

I'm afraid that a slap can slap a dead person, right?

Thinking of this, many viewers shuddered.

Who would have imagined that just when Bi Fang was asleep, there was a giant black bear passing by!

Even the distance between the two sides is less than 100 meters!

Bi Fang, who realized the danger, broke out in a cold sweat.

It's as if you're asleep in the middle of the night, but a murderer is standing close to your bed, staring at you with a knife!

Bi Fang, who was in danger of having a heart attack in the morning, tried to calm himself down, it was useless to panic now, the first thing was to judge the situation, determine which direction the black bear went, judge its motives, and then try to avoid it.

The footprints left by the black bear are very fresh, indicating that it has just left, and it must not be able to follow its footprints, which is purely hitting the muzzle of the gun.

Find a way to escape!

[Don't run away yet!] 】

[That is, while the bear didn't find out.] 】

[I heard that it's good to pretend to be dead when you meet a bear? 】

[Mom, I'm here]

"Don't panic, everyone, the bear must have discovered me now, so we must not run away blindly, and it's useless to pretend to be dead......"

Bi Fang looked at the water friends dancing in the live broadcast room and was quite speechless.

"First of all, the black bear has definitely discovered me, because the black bear's sense of smell is quite developed, even 7 times that of an excellent hunting dog, and can smell unfamiliar smells within 1 kilometer, and the shortest distance we have ever had with it is not even a hundred meters, it is impossible not to be detected."

"The reason why it didn't attack us at that time, I guess there are two reasons, either it is full, or there is something far more attractive to it than my hundred pounds!"

Bi Fang raised two fingers and began to analyze further.

"It's unlikely that he's full, because a black bear likes to sleep during the day and come out at night to feed, and if it's full, it shouldn't come out early in the morning, the only possibility is that there's something good nearby to attract it!"

It's last night's smoked rabbit meat and offal!

By the time Bi Fang analyzed this step, many sailors had already put the answer on the public screen.

[It's a meat bun! 】

[The internal organs will rot, and the black bear won't eat it, right?] That must be smoked rabbit meat! 】

[Damn, even the bears are attracted by rabbit meat, and I'm even more greedy......]

But Bi Fang shook his head and denied the speculation of the sailors.

"I had a friend in Alaska who said to me: 'If you meet a black bear, fight back, if you meet a brown bear, lie down, if you meet a white polar bear, then I wish you a good night.'" ”

"When encountering a brown bear, it may be useful to play dead, but it is never possible for a black bear, because black bears are omnivorous and will not refuse to eat scavengers, even if you die realistically, since it is obviously not decomposed, the black bear will only happily open your body cavity to see if your internal organs are edible!"

"And I hung the meat bun so high last night, it probably couldn't reach it, then we can almost be sure that it went to the place where we buried the internal organs last night!"

[, black bear scavengers!] The marketing number mistook me! 】

[Oh my God, so what now?] 】

When many sailors heard this, they were immediately anxious, this is not good, that is not good, is it difficult to wait for death?

Of course it can't be, sitting still is not Bi Fang's style!

No matter how tender and delicious a few pieces of internal organs are, they can't fill the black bear's belly, and when it comes back to its senses after eating, it will definitely come back to him!

And the rabbit that Bi Fang finally caught yesterday, how could it be so cheap for that beast?

Bi Fang is not reconciled!

He's going to get the bacon back!

Last night, when Bi Fang buried the internal organs and hung the rabbit meat, he kept an eye on it, and the routes of the two did not coincide, but were Y-shaped.

You know, the black bear is also known as the black blind man, not because of its poor eyesight, but because most of the black bears live in the mountains and forests, where there are many trees, if the trees are used as shelter, as long as the black bear's sense of smell is not locked, it is difficult for the black bear to find him.

As long as you can find cover at the downwind location, and then determine where to take shelter according to the direction of the wind, this plan is completely feasible!

Thoughts are like electricity, and Bi Fang has already made a plan.

He's going to take a gamble!

Just bet on him and the black bear, who is big enough!
