I can hardly hide my alien identity

Xie Chen looked around blankly, "Are we safe now?"

Fan Long nodded happily, looking at her husband's starry eyes that suddenly lit up like stars in the night, she thought that after the rest of her life, her husband would run over and give her a big hug.

The reality is, he did run over, and his eyes were shining, but...
"Quick, show me the little wings on your back."

"How about...you take me with me, I will take the bronze tripod, and then we will fly back to Daxia."

Seeing his whimsical appearance, Fan Long was a little bit heartbroken.

"We will definitely be shot down as alien creatures."

"And... what about your son, leave it alone?" The touching father-son relationship has been agreed.

Xie Chen said awkwardly: "Can you not tell your son about this?"

Just when the two of them were so indifferent to Little Wing, a voice interrupted their chat.

"Hey, did you fly into the sky just now? I saw it all."

Bai Rong was careless, as if he didn't notice the sudden vigilance of the two of them.

"You read it wrong."

As long as you don't admit it, it doesn't happen.

Bai Redundant didn't care about the attitudes of Xie Chen and Fan Long, but turned back, twisting like braids.

"Sangsang, are these really the little wings you made?"

"It can really fly into the sky."

Xie Chen was confused, "Is this thing made by the little girl in front of me?"

It's not that he looks down on people, but... has the little girl in front of her graduated from college?
How brave are the kids these days?Such amazing things can be made at such a young age.

Although they were engaged in archaeology, they also learned it step by step in a serious manner.

Sangsang: "I made a few small toys for the children."

"Are you eggy parents or happy parents?"

Xie Chen: ...Well, you guys know Versailles.

Hearing his son's name, Fan Cage's tense muscles relaxed little by little, so that he wasn't vigilant, but he didn't feel the tension at the beginning.

There had just been a sandstorm, which completely covered up the traces of their arrival, and the terrain position also changed a lot.

The hand-painted map that Wei Junhao bought from the guide at a high price in Wei Junhao's hand was completely useless.

No matter how anxious Xie Chen and Fan Long wanted to return now, they had no choice but to follow Sangsang and the others.

Who made them have neither food nor drinking water, and in the yellow sand all over the sky, even if they rose into the air, they could not see where they came from and where they went.

Now that they have a choice, to be conservative, Xie Chen and Fan Long don't want to take any risks.

Sangsang brought the two newcomers back to the previous oasis. If they hadn't seen the little wings behind the cage through the binoculars, they wouldn't have come here on purpose.

At this time, it was getting late, and the scorching temperature began to drop suddenly at the speed of minutes.

Suddenly, Xie Chen asked his soul, "Why are you all so dry?"

"Aren't you sweating?"

He and his wife were covered in sweat and blood, and it was very uncomfortable to stick to their bodies.

On the other hand, the few people in front of them, not to mention sunburned, didn't even see a drop of sweat.

Especially the little girl Sangsang, who was dressed very coolly, her exposed arms and thighs were tender and super white.

There is no protection on the whole body, which is too disrespectful to the direct sun in the desert.

Bai Redundant was proud now, "We wore Sangsang brand constant temperature thermal underwear."

"Focus, constant temperature."

Sangsang is very generous, and brought a few extra sets of special underwear for washing, which can just be distributed to them.

Xie Chen immediately felt as comfortable as a spring day when he put on a piece of silver underwear with a little streamer on his back.

Neither hot nor cold.

Fan Long was amazed. After nightfall in the desert, the sudden drop in temperature didn't affect her at all.

next day
After a comfortable night's sleep, everyone regained their spirits.

Xie Chen and Fan Long had extensive sunburns, even though they had been treated, they thought they still had to suffer.

Unexpectedly, after the sun rose, the high temperature under direct sunlight seemed to be automatically isolated from their skin.

Even standing under the sun, the two of them still felt the warm and cool breath.

"Wow, I haven't been back to China for several years, and the domestic black technology has developed to this level." Xie Chen sighed repeatedly.

Fan Long smiled and said, "Go back, we can apply to return to China."

"Fortunately, we have made a contribution, and we can go back to China quickly through the green channel."

"It will be difficult for others."

Xie Chen also shared some foreign news with Sangsang and the others, "In the first two months, everyone with a Daxia passport can return to China."

"It won't work until last month."

"Someone in our community failed the application. It is said that the reason for the rejection is that she has lived abroad for a long time and has no tax payment certificate in China. Her passport was directly destroyed."

"Now domestic policies are tightening more and more stringently."

Sangsang didn't know anything about this.

There are turmoil abroad, but the domestic people are still living and working in peace and contentment.

Fan Long, who was talking, suddenly stopped, his expression changed slightly, and he dug with his bare hands towards a certain piece of sand.

Xie Chen: "Sorry, professional habits."

After finishing speaking, he also joined the ranks of digging.

Not long after, a stone tablet covered by yellow sand appeared in front of everyone.

Fuzzy and messy lines can be vaguely seen on the stele.

It may have been eroded by time so much that you can't see what is painted on it at all, but you can tell that it looks like a special symbol, or is it a text?

Sangsang stared at the stele, her temples throbbing wildly.

The others gathered around Xie Chen and Fan Long, "Why is there a stone tablet here?"

"Maybe it was the dust storm yesterday that overturned the upper layer of sand."

Bai Redundant was still guessing what the painting on the stele meant, Xie Chen's face became more and more serious.

The husband and wife looked at each other, and they made a three-way comparison in unison.

Xie Chen forced a smile and said, "Impossible, and without professional tools, it's impossible to judge correctly just by looking at it with the naked eye."

Bai Redundant was impatient, looking at this and then at that, "What are you two talking about?"

Sangsang: "This stele has a history of [-] million years."

"Three hundred million years ago, Blue Star was still in the Carboniferous period, and dinosaurs hadn't even appeared yet." Fan Long said slowly, horrified and trembling.

Bai Redundant was still cheerful, "Haha, the dinosaurs [-] million years ago might have been small reptiles and amphibians."

Wei Junhao glanced at Bai Redundant like a fool, and said earnestly: "People still need to read more."

White redundancy: what does it mean?
The taciturn Lu Lin couldn't help but said, "Three hundred million years ago... civilization already appeared?"

What was it that created civilization [-] million years ago?
