Seeing that the topic was getting farther and farther away, Wei Kang hurriedly pulled the topic back and said: "As I mentioned just now, the mural in the New Dynasty period depicts the scene of ancient Egyptians taking cats to hunt in swamps and wetlands. The mural is dated between 3,500 and 3,000 years ago, and the cat in the mural is still full of mackerel patterns, and there appear to be no spots visible to the naked eye, which proves that the spots did not appear earlier than 3,000 years ago. ”

Wei Kang turned to Fina again, "So there is no direct evidence that it has spots mixed with mackerel patterns, but I personally think it appeared 2,500 to 1,500 years ago." ”

Anyway, it was still early before the plane took off, Zhang Zi'an was not in a hurry, watching their gossip and arguing, he admired Wei Kang in his heart, and actually greatly narrowed the scope of speculation without direct evidence.

He wanted to tell them the answer directly — don't guess, it was 2,000 years ago.

But he couldn't say, and even if he did, he couldn't trust them, for he couldn't explain how he knew, and if possible, he was going to find a way to prove the age of Fina's mixed pattern on the side during his trip to Egypt.

Du Xuetao, a nerdy type, lifted his glasses and asked cautiously: "Teacher, isn't Egypt a piece of yellow sand? Where do swamps and wetlands come from?"

Wei Kang shook his head, "I don't know much about this, it involves geography." ”

Zhang Zi'an interjected: "I've heard a thing or two, it should be caused by the drastic climate change, and with the growth of population, the original arable land can not support so many people, so people cut down a lot of forests, turning grasslands into arable land, and finally leading to uncontrollable desertification." A long time ago, the Sahara was a grassland and not a desert, just like Lop Nur was once the largest saltwater lake in China, and it is said that there were elephants in the Central Plains during the Shang Dynasty, which is unimaginable to modern people - except for the elephants in the zoo, of course, you can see them with a ticket. ”

Wei Kang and the others sighed, no one had anything to say.

This is a natural disaster as well as a man-made disaster.

Of course, they know how many amazing species will quietly disappear into the history of the earth in the process of climate upheaval, as if they had never existed, and can only make people sigh.

"Okay, let's stop standing here, Xiao Zhang still has a lot of formalities to do, right? Wei Kang said, "A lot of the luggage is our equipment, be careful when moving." ”

After all, they are all men, and they are very useful for rough work, even the thinnest Du Xuetao picked up the box where the gimbal camera was placed, and the strongest Gao Ke was even more hand-held.

Zhang Zi'an first took Feimas to the toilet - of course, the men's toilet, let it excrete its body, and then took it to check it in.

Then, he led Fina to the departure hall to meet the crowd.

He He sat on the suitcase, lowered his head to focus on the mobile game, and was called by Wei Kang several times before reacting.

"Why did you come here? I thought you got on the plane and left me here alone. As soon as she spoke, she grumbled.

"How is it possible, our luggage is still there. Gao Ke smiled, put down the suitcase, and leaned next to her, wanting to see what game she was playing.

"Oh! this is the cat? it's so cute!" He He noticed Fina, turned off the phone screen, jumped off the suitcase, and reached out to touch the top of Fina's head.

"Don't touch it!"

Zhang Zi'an has a headache for this kind of person who wants to touch strange cats and dogs without saying a word, if you want to say that they have a big heart or what, do you really think that they are the so-called pro-cat physique? Who is to blame for being bitten and scratched?

Fina had already raised one of her front paws, her eyes widened, and she let out a threatening scream, threatening to scratch.

He He was so frightened that he quickly withdrew his hand, "This cat is so fierce! it can't be a wild cat, right?"

In fact, if Fina really wanted to scratch her, where could she retract her hand, but it was in a hurry to return to Egypt and did not want to make a fuss.

"Not all cats have a good temper, especially this one, which likes nothing more than to scratch people, and if you don't want to get hurt, it's best not to provoke it - let's say okay, I'm not responsible for losing money, don't be unpredictable. Zhang Zi'an solemnly warned.

He He pouted, "It's really disappointing! By the way, didn't it mean that the actor dog also wanted to go with us? Where is it? It is said that the actor dog has a good temper and never refuses the fans' request for a group photo. ”

She looked around, but she didn't see any dogs.

"Pemmas is going to take the pet check-in, and will stay in the aerobic chamber used to transport the pet during the flight, if you plan to be the companion of it......" Zhang Zi'an stopped talking, not wanting to offend her too much.

He He: "......"

"I really wanted to take a picture with that dog, but I forgot about it. Gao Ke also said regretfully. Previously, their attention had been focused on Fina, and Pegasus was very low-key, and the light was completely obscured by Fina's strange coat color and markings.

Wei Kang interjected in time: "Okay, it's not too late to wait for the group photo to arrive in Egypt, there will be time then." While the plane has not yet taken off, I will first talk about the itinerary after arriving in Egypt, otherwise when we get on the plane, we will affect other passengers. ”

Everyone quieted down and listened to Wei Kang's explanation, but not everyone listened very seriously, Bi He He was bowing his head and playing with his mobile phone, while Gao Ke was watching her play with his mobile phone.

In fact, the itinerary has been set in advance, but sometimes the plan can't catch up with the change, so Weikang emphasized it again.

According to the plan, after arriving in Egypt, the first day will be free and easy to reverse jet lag.

Starting from the next day, Wei Kang and his four disciples visited the university in Cairo to hold a meeting with local biology scholars to discuss the evolution of domestic cats, this stage will last about three days, depending on the situation, only when Zhang Zi'an needs to appear with Fina, he will participate in the meeting, and other times he can move freely.

On the fifth day, they will ask local scholars to introduce reliable guides on their behalf, and rent off-road vehicles to enter the field expedition stage, the duration of which is to be determined.

In other words, Zhang Zi'an had almost four or five days to move freely, which made several other young people very envious.

It should be emphasized that this is only a predetermined arrangement, and the specific implementation will be flexible.

Wei Kang especially told Zhang Zi'an to try to go out as much as possible, after all, he was not familiar with the place in Egypt alone, he did not understand the language, and the local situation was unstable, so it would be bad if he encountered trouble.

Of course, Wei Kang was more worried about Fina, because Zhang Zian didn't tie a leash to Fina, he was afraid that if Fina ran away, the loss would be too heavy.

Zhang Zi'an verbally agreed, but in fact, he had already begun to plan the travel route in his heart.
