Live Wilderness Adventure

Chapter 867: King of Speed

Bi Fang used two parallel sticks to take the ostrich eggs out of the fire pit intact.

The pure white eggshell was slightly blackened by the flames, and it can be wiped with sand to give it a new look.

Irrigate it with cold water to cool it down a little. Bi Fang used a stone to pry the eggshell open, and pinched the eggshell bit by bit with his fingers.

The breeding season of birds and mammals is different. Their egg-laying period extends almost from spring to autumn. During this period, it is not surprising to eat any eggs.

Like poultry raised by humans, they can lay eggs almost all year round.

[It is said that the ostrich eggs will not be fried if they are directly baked in the fire? 】

【Why did it explode】

[Anyway, you can’t put eggs in the microwave, I was fried, the whole microwave oven was full of broken eggs, and then I was scolded by my mother, I have a deep memory]

Don't worry, it's unlikely.

Bi Fang scratched the sand with his fingers, apparently scalded.

A microwave oven can't heat an egg directly because it converts electricity into microwaves, which heat the food and heat it from the inside out.

The heat generated by the egg itself, when it hits the closed eggshell, cannot be released as the heat increases, resulting in an explosion.

Fire roasting, on the contrary, heats food through heat conduction. It is heated from the outside to the inside, and the possibility of explosion is much smaller. Even if it is fried, it is usually cracked, not exploded, so many people use the oven to make eggs. For example Salt Baked Eggs.

Of course, I just threw the eggs into the fire pit for convenience, like roasted sweet potatoes. Just to be on the safe side, don't follow me.

After pouring some cold water, the temperature of the eggshell finally dropped a bit, and hot air flowed out along the opening made by the stone, showing the amazing heat contained in it.

The ostrich shell is very thick and hot to the touch, so it is very difficult for Bi Fang to peel it off.

Harley next to him stood up and paced non-stop, licking his lips with his tongue, eager to try.

When the eggshell was completely peeled off, the delicate milky white protein was revealed in front of everyone, steaming slightly in the air.

this is yours.

Bi Fang cut two-thirds off with a knife, then cut it into small pieces to quickly cool down and dissipate heat, put it into a large eggshell, and handed it to Harley.

Harley, who had been hungry for almost two days, lowered his head and smelled it, and after confirming that there was no peculiar smell, he began to lick it happily.

Bi Fang used a knife to fork a piece of trembling egg white, put it into his mouth, and briefly tasted it.

[How is it, is it delicious? 】

【What does it taste like】

[I heard it's not tasty? It seems that the bigger the egg, the less delicious it is? 】

[Nonsense, I think the bigger the egg, the tastier it is. Goose eggs are much tastier than eggs. 】

【Ah, I feel that goose eggs taste very fishy, ​​and the taste is still very rough】

[Why do I feel that the taste of goose eggs is very delicate. . . The egg yolk does not choke, it is delicious with some soy sauce]

【Let's have a fight】

It tastes good. Bi Fang saw the barrage and expressed his feelings.

In terms of taste, I think it is much more delicate than eggs. The yolk is not so dry and delicious, but this kind of thing is like what is said in the barrage. Some people think goose eggs are not delicious, and some people think it is delicious. Dan’s impression is good, but I don’t know why, maybe it’s different from person to person?”

From a scientific point of view, the ostrich egg itself is the best egg, known as the 'king of all eggs'. On the one hand, it is the largest egg, and on the other hand, it is also the protein of ostrich eggs, with high calcium and iron content. Compared with other eggs, nutritionists say ostrich eggs are 'soft gold', and they are the first choice for 'food tonic' to enhance physical fitness and immunity.

After saying a few words, Bi Fang and Harley were immersed in cooking.

The food quickly enters the stomach and reacts violently with the long-awaited gastric acid.

The strong sense of hunger quickly faded from my mind, which lifted my spirits and seemed to relax a lot.

An ostrich egg weighs three catties. Although the eggshell is thick, the proportion is not very good compared to its own quality. One egg is enough for Bi Fang and Harley to have a meal.

[It's a pity that I didn't eat meat]

[Such a big ostrich can eat for a long time, right? 】

[To be honest, that one who rolled on the ground at the beginning was a bit stupid (eat melon)]

[Why the cheetah is faster, but still can't catch up]

In fact, the speed of the cheetah is not as fast as imagined. Many sources say that the speed of the cheetah is 110 kilometers per hour, or even 120 kilometers per hour, but this is not accurate.

Bi Fang bit the egg yolk, swallowed it and continued.

This data will not appear until 1957.

At that time, the cheetah was already known as the 'king of speed', which can be said to be a worldwide consensus, but no one has specifically measured the speed data of the cheetah.

Then in 1957, a photographer named Kurt Severin devised an experiment to test the speed of cheetahs.

He had a modified bicycle upside down on the ground with a long, strong piece of fishing line attached to the wheel, and a bag of meat was tightly tied to the end of the line.

A person turns the wheel, and the wheel drives the meat bag to move, and the cheetah will follow the meat bag and rush forward.

【Good guy, why do I have the sense of sight of a donkey and a carrot (dog head)】

【This is too simple】

【Is the measurement accurate? 】

[I feel that these things are not accurate. After all, if the animal is hungry, its status must be offline. If it is not hungry, why does it go after the meat bag with all its strength?]

[Fuck, it makes sense, isn't there no way to test it? 】

Then the experiment started. As soon as the starting pistol was fired, the man started to turn the wheel with full force. At that time, the speed of turning the wheel was almost reached the limit. Then the cheetah started chasing the bag of meat, and the stopwatch started timing.

After the intense experiment, it was calculated that the average speed of the cheetah was 71 miles per hour, which is about 110 kilometers per hour.

The results of this experiment were published in newspapers, and people all over the world knew that the speed of the cheetah had reached 110 kilometers per hour.

Even in the process of dissemination, some people said that the top speed of the cheetah was 120 kilometers per hour, which is the truth of the rumored speed of 120 kilometers per hour.

Bi Fang didn't finish his share of ostrich eggs. Although he was a little bit unsatisfied, he still kept some and slowly fed them to Jerry.

Jerry took the egg whites with both hands, stuffed his mouth full, and chewed non-stop.

Harley next to him pushed the two intact eggs over and tried to push them into the fire pit with his claws, but was stopped by an outstretched foot.

Eating without restraint is essentially a waste of food.

Bi Fang would not do this. He put the two eggs back into his backpack and continued to explain to the audience.

With the development of technology and the in-depth study of cheetahs, some scientists began to doubt whether the speed of cheetahs is as high as the legend.

In addition, the test tools in 1957 were relatively simple, such as wheels, stopwatches, starting guns, etc., and the error may be large, so the scientists planned to use a more scientific and accurate method to measure the speed of the cheetah.

After entering the 21st century, researchers from Yangguo installed the most advanced GPS positioning system on 367 cheetahs.

After hundreds of tests on cheetah hunting operations, it was found that the top speed of cheetahs was only 93 kilometers per hour - which is far lower than the original 110 or 120 kilometers that people said.

It should be noted that this is the highest value. It is a conclusion drawn after running thousands of times with nearly 400 cheetahs. It is not the average value or median.

And the speed of the ostrich is over 70. The difference between the two is actually not that big. Adding in the difference in stamina, as long as the ostrich makes a few sharp turns, the cheetah will not be able to keep up.

That's why I have always emphasized the necessity of ambushes. The cheetah is fast and is a top player in nature, but other animals are not bad either. They are all top-notch experts. If you are not careful, you may miss it.

After all, the entire nature is co-evolving, and the speed of both sides is like an arms race, basically growing at the same time.

[Co-evolution: refers to two or more species in a natural habitat. Due to the close ecological connection, their evolutionary processes are interdependent. When a species evolves, the selection pressure between species changes, and other species will adapt to it. evolutionary events, resulting in a phenomenon of high adaptation among species. 】

That's what this netizen said. This is co-evolution. There is a famous Red Queen hypothesis about this, which was proposed by Van Valen, an evolutionary biologist at the University of Chicago in 1973.

Arguing that there is co-evolution among different species.

For example, if a cheetah has a genetic mutation that causes the cheetah to run faster, then the antelope that is preyed on by the cheetah will also run faster.

Because, the antelopes that run slowly due to genetic reasons will be eaten by cheetahs, and the genes of these antelopes cannot be passed on to offspring, that is to say, the genes that run slowly will be eliminated by natural selection, which will cause the antelopes to run more and more quick.

Similarly, after the antelope's running speed becomes faster, the slow-running cheetah will be more difficult to prey on, and there will be a greater chance of being starved to death. Therefore, the evolution of the antelope is equivalent to screening the cheetah's genes, so that the cheetah running faster and faster.

【Damn, it turns out to be like this】

[I always thought that the speed of the cheetah was more than 100]

[Not necessarily, after all, there are Bolts among humans? 】

That's right. Bi Fang smiled, As the netizen said just now, you can't run when you're hungry, and you don't want to run when you're not hungry. You can know the average speed, but it's hard to measure the limit speed of animals. They're not like us humans. There are sports competitions as well.

So, maybe there really is a cheetah that can run at a speed of 100 kilometers per hour.

However, despite this, the cheetah is still the fastest running cat and the fastest animal on land.

The reason why the cheetah can run so fast is related to its streamlined body, long tail, powerful heart and lungs, light bones and other factors.

Come and listen to Harley's heartbeat.

Bi Fang greeted the drone, and the drone immediately flew to him and approached Harley at the same time.

Harley was very curious about the big black bird-like thing, and stretched out his hand, trying to take a picture of it, but Bi Fang held it down. Without being able to move, the audience heard its powerful heartbeat.

You pay attention to the cheetah's exhalation and inhalation, and then pay attention to its heartbeat.

[emmm, what's wrong? 】

【Why didn't I hear anything】

[Let’s talk about the big ones]

[If you want to say that, I can't keep a low profile. It's actually very simple. Just listen carefully and you'll know. Do you understand? 】

[Where are you from here? 】

[Drag it out, you will die! 】

Hahaha, what I reminded is quite obvious. Listen, when a cheetah inhales, its heartbeat speeds up, but when it exhales, its heartbeat slows down again.

In humans, it's respiratory sinus arrhythmia, a little irregular heartbeat, but it's normal in cheetahs.

This is because the cheetah's body needs a lot of acceleration in order to adapt to high-speed running. The heartbeat speeds up when inhaling to promote the supply of oxygen to give muscles high energy, and the heartbeat decreases when exhaling to allow carbon dioxide to be discharged at a normal speed.

【Awesome】

[It's over, why do I feel like I have the same problem]

[Looking at the live broadcast, I can see that something is wrong (distraught)]

[What happens to an irregular heartbeat? 】

Don't worry, it won't be a problem. Sinus arrhythmia itself will not affect the body. It is just a clinical manifestation, and normal people will have it, especially in the state of fatigue, drinking alcohol, drinking coffee, and insomnia. Rest more It'll be fine.

【Thank you Dr. Fang】

[After listening to Dr. Fang's words, my legs are no longer sore, my waist is no longer painful, and I can go up to the eighth floor in one go]

【You know how to rhyme】

【skrskr】

After a simple lunch, Bi Fang replenished the water resources and continued on the road with Harley.

As the geographical location gets closer to the north, the vegetation on the surface gradually becomes sparser, and many places even change from the original hard land to sandy land.

I don't know how many days the wet season will arrive. It should be these few days.

Looking at the dry land around him, Bi Fang felt that all the water in his body was being lost, as if being sucked away by the ground under his feet.

Obviously the temperature is not high, but there is such an illusion.

At the same time, a small plant on the ground also attracted his attention.

Yesterday I showed how to track animals to find water sources. In fact, normally speaking, the roots of many plants can also meet our needs. Look at this.

Bi Fang squatted down and lifted up the plant that looked like a tree root.

It was a plant that looked like roots, and it didn't have too many branches. It was a question mark whether it was ten centimeters tall.

The inconspicuousness is really brought into play into the mechanism, and normal people don't even take a second look at it.

But Bi Fang recognized it immediately.

Harley behind him took this opportunity to rest on the ground.

【What is this】

[Can replenish water, cactus (confirmed)]

Hey, you really guessed it right, this is a cactus.

Bi Fang took out his dagger, inserted it directly into the soil, dug up the hard pit, and then dug up the soil.

This is a cactus plant called Odia. It is not a cactus in the traditional sense, but its roots are very large. When they are hungry and thirsty, many African indigenous people will find this plant to quench their thirst.

But it is more difficult to find. You can see how inconspicuous it is by looking at it. It is no different from normal tree roots.
