Bi Fang used two parallel tree sticks to completely remove the ostrich eggs from the fire pit.
The pure white eggshell is slightly blackened by the flames, and can be wiped with sand to make it look new again.
Pour it with cold water and cool it down slightly. Then use a stone to pry open the eggshell, and use your fingers to peel the eggshell apart little by little.
"The short breeding period of poultry 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."
"For example, poultry raised by humans can lay eggs almost all year round."
[By the way, won’t ostrich eggs explode if you put them directly in the fire? 】
[Why did it explode?]
[Anyway, you can’t put eggs in a microwave oven. I was once fried. The whole microwave oven was full of broken eggs. Then I was scolded by my mother. I have a deep memory.]
"Don't worry, it's unlikely."
Bi Fang held the sand in his fingers and was obviously burned.
"Microwave ovens cannot heat eggs directly because they convert electricity into microwaves, which use microwaves to generate heat in the food and heat it from the inside out."
"The heat generated by the egg itself hits the sealed eggshell. As the heat becomes more and more, it cannot be released, resulting in an explosion."
"Fire roasting, on the contrary, heats food through heat conduction, heating from the outside to the inside, and the possibility of explosion is much smaller. Even if it is fried, it usually cracks, not explodes, so many people use the oven to make eggs, for example
Salt-baked eggs.”
"Of course, I personally just throw the eggs into the fire pit for convenience, just like roasting sweet potatoes. To be on the safe side, you should not follow my example."
After pouring some cold water, the temperature of the eggshell finally dropped a bit. Along the opening opened in the stone, hot air flowed out, showing the amazing heat contained in it.
The ostrich shell is very thick and hot to the touch, so it is very difficult to peel it off.
Harley next to him got up and kept pacing, licking his lips, eager to try.
When the eggshell is completely peeled off, the delicate milky white protein is revealed to everyone, steaming slightly in the air.
"this is yours."
Bi Fang cut off two-thirds of it with a knife, then cut it into small pieces to quickly cool down, 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. After confirming that there was no peculiar smell, he licked and ate it happily.
Bi Fang used a knife to pick up a piece of trembling egg white, put it into his mouth, and tasted it briefly.
【How is it, is it delicious?】
【What does it taste like】
[I heard it’s not delicious? It seems that the bigger the egg, the less delicious it is?]
[Nonsense, I feel that the bigger the egg, the better it tastes. Goose eggs are much more delicious than chicken eggs.]
[Ah, I feel that goose eggs taste very fishy and the texture is very rough]
[Why do I feel that the texture of goose eggs is very delicate...the yolk is not choking, and it tastes delicious when dipped in 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's much more delicate than eggs, and the yolk is not so dry. It's delicious. But as mentioned in the barrage, some people think goose eggs are not delicious, while others think they are delicious. I like goose eggs.
The impression of eggs is good, I don’t know why it is like this, maybe it varies from person to person, right?”
"From a scientific point of view, the ostrich egg itself is the best egg, known as the 'King of Eggs'. On the one hand, it is the largest egg, and on the other hand, ostrich eggs have high protein, calcium, iron and other contents.
Compared with other eggs, nutritionists call ostrich eggs 'soft gold' and the first choice of 'food supplement' to enhance physical fitness and improve immunity."
After a few brief words, Bifang and Harley were immersed in cooking.
Food enters the stomach quickly and reacts violently with the stomach acid that has been waiting for a long time.
The intense hunger quickly subsided from my mind, making my whole body feel refreshed and feeling much more relaxed.
An ostrich egg weighs three kilograms. Although the eggshell is thick, the proportion is not very good compared to its own mass. One egg is enough for Bifang and Harley to have a meal.
[It’s a pity that I didn’t eat meat]
[An ostrich that big can be eaten for a long time, right?]
[To be honest, the one rolling on the ground at the beginning was a bit stupid (eat melon)]
[Why is the cheetah faster but still unable to catch up?]
"Actually, the speed of cheetahs is not as fast as imagined. Many data say that the speed of cheetahs 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 would not appear until 1957."
"At that time, the cheetah was already known as the 'King of Speed'. It can be said to be a world consensus, but no one has ever measured the specific speed data of the cheetah's running speed."
"Then in 1957, a photographer named Kurt Severin designed an experiment to test the speed of cheetahs."
"He put a modified bicycle upside down on the ground. The wheels of the bicycle were connected to a very strong and long fishing line, and a bag of meat was tightly tied to the end of the fishing line."
"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 the sense of sight of a donkey and a carrot (dog head)]
[This is too crude]
[Can the measurement be accurate? 】
[I feel that these things are not very accurate. After all, if the animal is hungry, its status is definitely not online. If it is not hungry, why is it chasing the meat bag with all its strength]
[Damn, that makes sense, isn’t there no way to test it? 】
"Then the test began. As soon as the starting gun was fired, the person began to turn the wheel with all his strength. At that time, the speed of turning the wheel almost reached the limit. Then the cheetah started chasing the meat bag, and at the same time the stopwatch started timing."
"After the intense trials, it was calculated that the cheetah's average speed reached 71 miles per hour, which is approximately equivalent to 110 kilometers per hour."
"The results of this test were later published in a newspaper, and people all over the world knew that the cheetah's speed reached 110 kilometers per hour."
"Even in the process of spreading, some people even said that the cheetah's top speed is 120 kilometers per hour. This is the truth of the 120 kilometers per hour rumored speed now."
Bi Fang did not finish his share of ostrich eggs. Although he was still a little unfinished, he still kept some, held them in his hand and slowly fed them to Jerry.
Jerry took the egg white with both hands, stuffed his mouth full, and kept chewing.
Harley next to him pushed two intact eggs over and tried to push them into the fire pit with his claws, but unfortunately he 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 science and technology and the in-depth study of cheetahs, some scientists have begun 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 errors may be larger, so scientists planned to use a more scientific and accurate method to measure the cheetah's speed."
"After entering the 21st century, researchers from China installed the most advanced GPS positioning system on 367 cheetahs."
"After hundreds of tests on cheetahs hunting, it was found that the cheetah's top speed is only 93 kilometers per hour - which is far lower than the 110 kilometers or 120 kilometers per hour that people originally said."
"It should be noted that this is the highest value. It is the conclusion reached after running thousands of times with nearly 400 cheetahs. It is not the average value or the median value."
"And the speed of the ostrich exceeds 70, so the gap between the two is actually not too big. Coupled with 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 always emphasize the necessity of ambush. Cheetahs are fast and are the top masters in nature, but other animals are not bad either. They are all top-notch masters. If you are not careful, you may miss."
"After all, the entire nature is co-evolving, and the speed of both parties is like an arms race, basically growing simultaneously."
[Co-evolution: refers to two or more species in a natural habitat. Due to close ecological connections, their evolutionary processes are interdependent. When one species evolves, the selection pressure between species changes, and other species will adapt accordingly.
evolutionary events, resulting in a highly adaptive phenomenon among species.】
"This is what this netizen said. This is co-evolution. There is a famous Red Queen hypothesis about this. It was proposed by Van Valen, an evolutionary biologist at the University of Chicago, in 1973."
"The idea that coevolution exists between different species."
"For example, if a cheetah has a genetic mutation that causes the cheetah to run faster, then the antelope preyed by the cheetah will also run faster."
"Because, due to genetic reasons, antelopes that run slowly will be eaten by cheetahs, and the genes of these antelopes cannot be passed on to future generations. In other words, the genes that run slowly will be eliminated by natural selection, which will cause the antelopes to run faster and faster.
quick."
"Similarly, when the antelope's running speed becomes faster, it will be more difficult for the slower cheetah to hunt, and there will be a greater chance of starving to death. Therefore, the evolution equivalent to the antelope will also screen the cheetah's genes, allowing the cheetah to
The running speed is getting faster and faster.”
[Damn, that’s what it is]
[I always thought that a cheetah could have a speed of over 100]
[Not necessarily, after all, there is also Bolt among humans?]
"That's right." Bi Fang smiled, "As a netizen just said, you can't run when you are hungry, and you don't want to run when you are not hungry. You can know the average speed, but it is difficult to measure the ultimate speed of animals. They are not like us humans.
There are also sports competitions.”
"So, maybe there is a cheetah that can run at a speed of 100 kilometers per hour."
"However, despite this, the cheetah is still the fastest cat and the fastest animal on land."
"The reason why a cheetah can run so fast is related to its streamlined body, long tail, strong heart and lungs, light bones and other factors."
"Come and listen to Harley's heartbeat."
Bi Fang called out to the drone, which immediately flew to his side and approached Harley at the same time.
Harley was very curious about the big black bird-like thing. He stretched out his hand and tried to take a picture of it. Unfortunately, he was held down by Bifang. Unable to move, Harley allowed the audience to hear its strong heartbeat.
"You guys pay attention to the cheetah's exhalation and inhalation, and then pay attention to its heartbeat."
【emmm, what happened? 】
[Why didn’t I hear anything?]
[Let’s talk about it in a big way]
[If you say that, I can’t keep a low profile. It’s actually very simple. Just listen carefully and you’ll know. Do you understand? 】
【Are you across here from here? 】
[Drag him out and he will be killed!]
"Hahaha, I've made it quite obvious. Listen, when a cheetah inhales, its heartbeat speeds up, but when it exhales, its heartbeat slows down."
"In humans, this would be respiratory sinus arrhythmia, a minor condition of irregular heartbeat, but it's normal in cheetahs."
"This is because the cheetah's body needs a lot of ability to accelerate in order to adapt to high-speed running. When inhaling, the heartbeat accelerates to promote the supply of oxygen to provide high energy to the muscles. When exhaling, the heartbeat decreases 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?]
[Watching the live broadcast, I can see something is wrong (devastated)]
【What happens if there is irregular heartbeat?】
"Don't worry, it won't be bad. Sinus arrhythmia itself will not have an impact on the body. It is just a clinical manifestation. Normal people will also have it, especially when they are tired, drink alcohol, drink coffee, or have insomnia. Get more rest.
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 breath]
[You know how to rhyme]
【skrskr】
After a simple lunch, Bi Fang replenished his water supply and continued on the road with Harley.
As the geographical location moves further and further north, the vegetation on the surface gradually becomes sparser, and many places even change from the original hard soil to sandy land.
“I don’t know how many days there will be until the wet season arrives, it should be these days.”
Looking at the dry land around him, Bifang felt as if all the moisture in his body was being lost, as if it was being sucked away by the earth beneath his feet.
The temperature is obviously not high, but I still have 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, the roots of many plants can also meet our needs. Look at this."
Bi Fang knelt down and lifted up the plant that looked like tree roots.
It was a plant that looked like roots, and it didn't have many branches. It was questionable whether it was even ten centimeters tall.
It really uses inconspicuousness to its mechanism, and normal people won't even take a second look.
But Bi Fang recognized it at a glance.
Harley behind him took this opportunity to lie down on the ground and rest.
【What is this】
[Can replenish water, cactus (confirmed)]
"Hey, you guys guessed it right, this is a cactus."
Bi Fang took out his dagger, inserted it directly into the soil, dug up the hard soil 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 natives will look for this plant to quench their thirst."
"But it's harder to find. You can tell by its appearance how inconspicuous it is. It's no different from a normal tree root."
