Bi Fang used two parallel sticks to remove the ostrich eggs from the fire pit.

The white eggshell was slightly blackened by the flames, and it can be wiped with sand and refreshed.

Pour it with cold water to cool it down slightly, and then pry the eggshell open with a stone, pinching his fingers to peel the eggshell apart little by little.

"Birds and mammals don't have the same narrow and short breeding period, and their laying period extends almost from spring to autumn, and it's not surprising that they eat any eggs during this time."

"It's like a human poultry, which can lay eggs almost all year round."

[Anyway, won't ostrich eggs be fried if they are roasted directly in the fire?] 】

[Why is it fried?]

[Anyway, you can't put eggs in the microwave, I was fried, the whole microwave oven is broken eggs, and then I was scolded by my mother, I remember it deeply]

"Don't worry, it's not likely."

Bi Fang's fingers were rubbing the sand, obviously burned.

"The microwave oven can't heat the eggs directly, because it converts electricity to microwaves, and through microwaves, the food generates heat and heats it from the inside out."

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

"On the contrary, fire roasting is to heat food through heat conduction, heating from the outside to the inside, the possibility of explosion will be much smaller, even if it is fried, it is usually cracked, not exploded, so many people will use the oven to make eggs, such as salt-baked eggs."

"Of course, I'm just trying to make it convenient, just throw the egg into the fire pit, like baked sweet potatoes, for the sake of safety, everyone should not learn from me."

After pouring some cold water, the temperature of the eggshell finally dropped a little, and the heat gushed out along the hole in the stone, showing the amazing heat contained in it.

The ostrich shell is very thick and hot to the hand, so it is very difficult to peel it off.

Harley, who was next to him, got up and paced, his tongue licking his lips, eager to try.

When the eggshell is peeled whole, the delicate milky white protein is exposed in front of everyone, and it is slightly steaming in the air.

"It's yours."

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

Harley, who had been hungry for almost two days, lowered his head and sniffed it, and after confirming that there was no smell, he licked and ate it happily.

Bi Fang picked up a piece of trembling egg white with a knife and put it into his mouth, and tasted it briefly.

[How's it going, is it delicious?] 】

[What a taste]

[I heard it doesn't taste good? It seems that the bigger the egg, the worse it tastes? 】

[, I feel that the bigger the egg, the better, and the goose egg is much better than the egg.] 】

[Ah, I feel that the goose eggs taste very fishy, and the texture is still very rough]

[How do I feel that the taste of goose eggs is very delicate... The egg yolk is not choked, and it is delicious to dip it in soy sauce]

[Let's fight]

"It tastes good." Bi Fang saw the barrage and said how he felt.

"I think the taste is much more delicate than eggs, the yolk is not so dry, delicious, but this kind of thing is like what was said in the barrage, some people think goose eggs are not delicious, and some people think they are delicious, my impression of goose eggs is good, I don't know why this is so, it may vary from person to person, right?"

"From a scientific point of view, the ostrich egg itself is the most eggs, known as the 'king of eggs', on the one hand, it is the largest egg, on the other hand, it is also the protein of the ostrich egg, calcium, iron and other content are higher than other eggs, nutritionists call the ostrich egg is 'soft gold', is to enhance the physique, improve the immunity of the 'food supplement' first choice."

After a few words, Bi Fang and Harley immersed themselves in dry rice.

The food quickly enters the stomach and reacts violently with the stomach acid that has been waiting for a long time.

The intense hunger pang quickly subsided from his mind, and the whole person's spirits were lifted and he seemed to be much lighter.

An ostrich egg weighs three pounds, and although the eggshell is thick, compared to its own mass, the proportion is not too good, and one egg is enough for Bi Fang and Harley to eat.

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

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

[To be honest, it was a bit stupid to roll on the ground at the beginning (eating melons)]

[Why is the cheetah faster, but it 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 12, but this is not accurate."

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

"It wasn't until 1957 that this data appeared."

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

"Later, in 1957, a photographer named Kurt Severin designed an experiment to test the speed of cheetahs."

He turned a modified bicycle upside down on the ground, and the wheels of the bicycle were attached to a very strong, long fishing line, and the end of the line was tightly tied to a bag of meat.

"When a person turns the wheel, 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 a donkey, the sense of déjà vu of radish (dog head)]

[This is too simple, isn't it?]

[Is the test accurate?] 】

[I feel that these things are not very accurate, after all, if the animal is hungry, the state is definitely not online, if it is not hungry, why should it chase the meat bag with all its might]

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

"Then the experiment began, and as soon as the starting gun went off, the man began to turn the wheels with all his might, and at that time the speed of the wheels was almost at the limit, and then the cheetah started to chase the meat bag, and the stopwatch began to timer."

"After intense experiments, the average speed of the cheetah was calculated to be 71 miles per hour, which is equivalent to about 110 kilometers per hour."

The results of this test were later published in newspapers, and the whole world knew that cheetahs could reach speeds of up to 110 kilometers per hour.

"Even in the process of spreading, some people even say that the maximum speed of the cheetah is 120 kilometers per hour, which is the truth of the 120 kilometers per hour that is now rumored."

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

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

Harley, who was nearby, 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 moderation 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 science and technology and the deepening of the study of cheetahs, some scientists have begun to wonder if the speed of cheetahs is as high as the legend says."

"Coupled with the fact that the 1957 test tools were relatively simple, such as wheels, stopwatches, starting pistols, etc., the error could be large, so scientists planned to use a more scientific and accurate way to measure the speed of cheetahs."

"In the 21st century, researchers from the central government equipped 367 cheetahs with the most advanced GPS positioning system."

"After hundreds of tests of cheetah hunting operations, it was found that the cheetah had a top speed of only 93 kilometres per hour – far below the original 110 kilometres or 120 kilometres that people had originally said."

"Note that this is the highest value, which is the conclusion reached after nearly 400 cheetahs and thousands of runs, and it is not an average or median."

"And the ostrich's speed is also more than seventy, the difference between the two is actually not too big, plus the difference in endurance, as long as the ostrich makes a few sharp turns, the cheetah will not be able to keep up."

"That's why I keep emphasizing the necessity of ambushes, the speed of the cheetah is fast, it is the top master in nature, but the other animals are not bad, they are all first-class masters, and if you are not careful, you may miss."

"After all, the entire natural world is co-evolving, and the speed of the two sides is like an arms race, basically growing simultaneously."

[Co-evolution: refers to the interdependence of two or more species in a natural habitat due to their close ecological connection, when a species evolves, the selection pressure between species changes, and other species will have evolutionary events that adapt to it, resulting in a phenomenon of high adaptation between species. 】

"That's what this netizen said, this is coevolution, and there is a famous Red Queen hypothesis about this, which was put forward by Van Wallen, an evolutionary biologist at the University of Chicago in the ugly country, in 1973."

"It is believed that there is co-evolution between 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, because the antelope that runs slowly due to genetic reasons will be eaten by the cheetah, the genes of these antelopes cannot be passed on to their offspring, that is, the genes that run slowly will be eliminated by natural selection, which will cause the antelope to run faster and faster."

"Similarly, when the antelope runs faster, the slower cheetah will be more difficult to prey on and will have a greater chance of starvation, so the evolution of the antelope will also screen the genes of the cheetah to make the cheetah run faster and faster."

[Damn, so that's it]

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

[Not necessarily, after all, there is also Bolt in the human race?] 】

"That's right." Bi Fang smiled, "Just like what netizens said just now, you can't run when you're hungry, you don't want to run if you're not hungry, the average speed can be known, but the limit speed of animals is difficult to measure, and they don't have sports competitions like us humans." ”

"So, maybe there are cheetahs that can run at speeds of 100 kilometers per hour."

"Still, despite this, cheetahs are still the fastest cats and the fastest on land."

"The reason why a cheetah can run so fast is related to its streamlined body, long tail, strong heart and lungs, and light bones."

"Listen to Harley's heartbeat."

Bi Fang beckoned to the drone, and the drone immediately flew to his side, and at the same time approached Harley.

Curious about the big black bird-like thing, Harley reached out and tried to shoot it, but was held down by Bi Fang, and the audience could hear its powerful heartbeat while unable to move.

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

[emmm, what's wrong?] 】

[I didn't hear anything]

[Let's talk about it]

[If you want to say that, I can't be low-key, it's actually very simple, just listen carefully and you know, do you understand? 】

[What are you doing here and here?] 】

[Drag it out, the sun will die!] 】

"Hahaha, what I prompted is quite obvious, you see, when the cheetah inhales, the heartbeat will accelerate, but when the exhale, the heartbeat will slow down."

"If it's human, it's respiratory sinus arrhythmia, a small problem with an irregular heartbeat, but it's normal in cheetah."

"This is because the cheetah's body needs a lot of ability to accelerate in order to adapt to running at high speeds, the heartbeat is accelerated during inhalation to promote the supply of oxygen to give high energy to the muscles, and the heartbeat is lowered during exhalation to allow carbon dioxide to be expelled at a normal rate."

【Awesome】

[It's over, how do I feel like I have such a problem]

[Watch the live broadcast and see that something is wrong (grief)]

What happens if there is an irregular heartbeat? 】

"Don't worry, it won't be good, sinus arrhythmia itself will not affect the body, it is only a clinical manifestation, normal people will also have it, especially in a state of fatigue, drinking, coffee, insomnia, rest more and it will 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 breath]

[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 farther and farther north, the vegetation on the surface gradually becomes more sparse, and many places even change from the original hard soil to sandy land.

"I don't know how many days the wet season will come, it should be these days."

Looking at the arid earth around him, Bi Fang only felt that the water in his body was being lost, as if he had been sucked away by the earth 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 you how to track animals for water, and in fact, normally speaking, the rhizomes of many plants can meet our needs, you see this."

Bi Fang crouched down and lifted the plant, which looked like the roots of a tree, up.

It was a root-like plant, and it didn't have many branches, and there was a question mark over whether it was ten centimeters tall.

It's really a mechanism that makes it inconspicuous, and normal people don't even look at it.

But Bi Fang recognized it at a glance.

Behind him, Harley took the opportunity to lie on the ground and rest.

[What's this]

【Hydrates, cactus (convinced)】

"Hey, you guessed it right, it's a cactus."

Bi Fang took out a dagger and plunged it directly into the dirt, digging up the hard pit and digging up the earth.

"It's a cactus plant called Odia, not a cactus in the traditional sense, but it has very large roots, and many indigenous people in Africa look for this plant to quench their thirst when they are hungry and thirsty."

"But it's harder to find, and you can tell how inconspicuous it is, just like a normal tree root."
