Due to its small size, the underwater robot was built before the Higa.

Wang Xika named the Gundam Water Machine No. 1.

This underwater robot is designed to be 2,000 meters deep, but Wang Xika is not ready to dive to such a deep place, he only plans to go to the 1 kilometer ancient city to explore it himself, and he always suspects that the ancient city is the lost Atlantis.

On a sunny afternoon, Wang Xikayoa went to explore the ancient city.

Ah Snake also gave a thumbs up when he saw Wang Xika wearing a diving robot, and said, "Your current set looks much more handsome than the previous one." ”

Ah Snake is talking about the non-powered diving suit before Wang Xijia.

"That's nature, I'm swimming as fast as you are in this wetsuit. Wang Xika said.

"Really, do you want to see it?" Snake clearly disagreed.

"It's better than that," Wang Xika said.

The two began to swim in the sea at full speed, Ah Snake was the fastest swimmer, with a speed of about 60 kilometers per hour, and Wang Xijia's wetsuit was designed at a speed of about 60 kilometers per hour. The two of them raced in the sea for a while, and sure enough, they were indistinguishable.

"Yes, you'll be cheeky in this suit!" said Snake excitedly.

"Uh-huh", Wang Xika is also quite satisfied with the performance of this water machine No. 1, and feels that he has a feeling of Iron Man.

He first followed Ah Snake to a place 300 meters underwater to see if there was any difference between this home and the 100-meter one. It seems that the indoor arrangement of 300 meters and 100 meters is no different, but the scenery outside is different, the underwater 300 meters is the favorite distance of the animals, and there are many sharks, whales, dolphins and so on at this depth.

A great white shark was very curious when it saw Wang Xika's strange equipment, swam over to observe it carefully, and almost scared Wang Xika to death. Fortunately, he was driven away by a snake in time.

The depth of the dive came to a thousand meters. Since it is difficult for sunlight to reach this depth, the color of the water here is already very dark, and Wang Xijia has to turn on the lighting.

Ah Snake is simply envious and jealous of Wang Xijia's equipment - for many years, the distance of their gills to 1,000 meters has basically relied on naked eye observation, and there is no lighting equipment at all.

Wang Xika turned on the searchlight and found that the sea creatures around her had turned into giant squid and whales. I don't know if it's an illusion, Wang Xijia always feels that something seems to be watching him in the distance.

"Can you feel it? Somebody is watching us. Wang Xijia asked.

"Oh, you're talking about the sea people, they occasionally come to this generation for activities, and it has nothing to do with the fact that our gills don't interfere with the river water. Snake said.

"But don't the sea people have no eyes, how can they see us?" asked Wang Xijia.

"Although the sea people don't have eyes, they can feel us with their bodies, just like eyes. Snake said.

Wang Xijia knew that bats relied on ultrasound to detect their locations, could it be that the sea people also had this ability? With doubts, he stepped into the ancient city under the sea.

It doesn't look real from the photos, really in this ancient city, Wang Xijia only feels that this city is very familiar, and it seems that he has seen it somewhere. Where are the temples in the city, the streets......

Isn't this exactly the same as the layout of the imperial city in Egypt? Except for the location of the pyramids, the rest of the buildings seem to have been seen in the Egyptian royal palace.

Wang Xika dived into the underwater pyramid and made a detour behind it, only to see that in addition to the poem about monkeys and eggs, there was also a mural painted on it. Due to the passage of time, the paint on the frescoes has fallen off, but it can be seen that the frescoes are exactly the same as those of the Egyptian royal palace. The Egyptian one was painted by the high priest Anubis, so who painted this one here?

Wang Xika was about to take a picture when he suddenly came across a metal box, which was already rusty and covered with moss. When I opened the box, I saw that it was a stack of things packed in a moisture-proof plastic bag. I can't see it well underwater, but it just feels like a notebook or something. Wang Xika stuffed this thing into his backpack and waited back to the shore to check it.

"How can there be a moisture-proof plastic bag under this water? Could it be that there was a civilization that could make plastic bags before the ancient city was lost?" Wang Xika finished walking around the main city with a suspicious stomach, thinking that the contents of the plastic bag couldn't stay in the water anymore, so he said hello to Snake and returned to the shore.

Back at his studio by the sea, Wang Xika couldn't wait to open the plastic bag, which contained a black leather wallet. There was a thick stack of manuscript paper in the clip, and I don't know how many years it had been soaked in the seawater, but because it was well protected, it was not damp at all.

When I opened the first page of the manuscript paper, I saw that it was written in elegant blue-black ink in neat imitation Song style: "Xingtu Travel Agency"

Dedicated to my friend He Fan.

What is strange is that this character is actually Chinese Simplified, the same script used by Wang Xijia. Wang Xika continued to flip down, only to see that the back was densely packed with words.

The first page reads: "1. Ideals and Reality"

This seems to be a title, and as I continued to read it, I saw a story written in the back:

The sun has long since set, the moon has risen, and it is a full moon night. The summer cicadas are still chirping tirelessly, and the frogs in the pond can't bear the loneliness and sing one after another. In the ensemble of summer cicadas and frogs, Du Jianguo, a third-grade elementary school student who had just finished his homework, excitedly fiddled with the astronomical telescope his father bought for him and looked at the moon. It was a brand-new 500x astronomical telescope, which was used as a reward for his 100 points in Chinese and mathematics in his last exam. Although Du Jianguo doesn't like to do homework, his studies are not bad, and he thinks that he can be a scientist or an astronaut when he grows up.

While looking at the moon, he asked, "Mom, Mom, why is the surface of the moon so pitted?"

Du Jianguo's mother was gently knitting a sweater next to him, and when he heard his son's question, he immediately became serious, and replied seriously: "Because the moon baby doesn't listen to his mother, he always smokes, drinks and stays up late when he grows up, so his face is full of pockmarks." Jianguo, you have to listen to your mother in the future, but you can't smoke or drink!"

"Hmm!" Du Jianguo agreed to his mother heavily, he stared intently at the lunar crater in the telescope, thinking that he must study hard and take his mother to the moon for a walk in the future to have a look.

It was 2300 A.D., and with the civilian use of curvature-driven technology, interstellar travel had become commonplace, let alone moon-travel. But none of Du Jianguo's family has ever been to the moon, because their family's tradition is that they don't like to travel very much. Not to mention going to other planets, even if you go to other countries and other provinces, you don't have any interest--just watch it on TV, why waste that money? As Du Jianguo grew up, he gradually discovered that his mother didn't really like to travel, because his mother often envied the square dance sisters who had nothing to do to travel. An important reason why the family rarely travels is that they don't have money.

This strengthened Du Jianguo's determination to study hard, and in the future, he will study and make a lot of money, and he will go to play wherever he wants. It's a pity that it's easy to make up your mind, but it's hard to stick to it. Although Du Jianguo wants to spend all his time studying, he can't help but be distracted every time he studies for an hour and a half, and he always can't help but flip through some miscellaneous books. What he likes to read most are the ancient books handed down by his ancestors, such as "PHS Roaming the Future" and "Doraemon" or something, which are basically 20th century books, and now they don't seem outdated at all, which makes people have to sigh at the power of the imagination of the ancients. The only regret that he feels is that it is now the 24th century, but those intelligent robots Doraemon, which should have been invented in the 22nd century, the bamboo dragonfly flying machine worn on the head, and the time machine in the drawer have not yet been invented, which shows that the scientists in the last few hundred years are not as good as the generation. If there was a Doraemon to accompany him, how easy it would be to learn.

Du Jianguo made up his mind to study hard, and at the same time, he began to read miscellaneous books after studying for a few minutes, and slowly grew up. Strange to say, he hasn't scored 100 since he decided he wanted to be a scientist. Many things in the world are like this, and the more you want to get it, the less you can't get it. Gradually, he also recognized the reality, and no longer fantasized about being able to do Doraemon's help solve his study problems, nor did he want to be a scientist. His ideal became that as long as he could support himself and not cause trouble to his mother. Fortunately, it is still easy to support yourself in this era, even if you don't do anything, you can eat subsistence until you die, as long as you are not afraid of losing face.

Du Jianguo University studied a major in foreign (planetary) economics and trade, this major does not require so high scores in the college entrance examination, basically you can study as long as you pass every subject. During his college years, Du Jianguo learned to smoke and drink, and completely reneged on the promise he made to his mother many years ago, just as he turned his back on his ideal of being a scientist, and he has accepted the fact that he is an ordinary person. Anyone can turn his back on his ideals, isn't it? Du Jianguo just finished college, ended his school life, and began to look for a job. Although his profession is the economy and trade of foreign planets, it is basically useless. Because human beings have not discovered aliens, no matter which planet they are on, they are doing business with earthlings, and others will not do business with you just because you have studied this major. So Du Jianguo decided that it was better to do work outside of his major.

The first thing he thought of was to become a taxi driver, asked his family for some money, and got some money from his friends, bought the cheapest curvature spaceship and started running business. After running for a few days, he found that the taxi driver was too tired to do this job, and he couldn't make too much money, and occasionally encountered drunk passengers who vomited a boat and it was too troublesome to clean, he saw that the classmates in the circle of friends seemed to be doing e-commerce, and he sold the spaceship and started to do e-commerce as soon as he gritted his teeth. After doing it for a while, he found that the e-commerce industry relied on cheating money, which was against conscience, and the income was not as good as renting. This time, he learned to be obedient, no longer looking for these vain occupations, and decided to find a way to live from the "clothing, food, housing and transportation" that human beings just need, so he stopped doing e-commerce, built a freezer and bought a few barbecue grills and began to sell barbecue. Selling barbecue is a bit like driving a taxi, both belong to the service industry, and you can see all kinds of people every day. Of course, compared with renting, the advantage of selling barbecue is that you don't have to endure crowded traffic, and the disadvantage is that you always meet all kinds of "acquaintances" to take care of the business. Fortunately, Du Jianguo doesn't care much about money, as long as he doesn't lose money, he is also willing to invite friends to have a few meals to increase his popularity.

Du Jianguo's favorite customer is Wang Qianyuan, Wang Qianyuan is Du Jianguo's hair, but he never asks for a discount every time he comes to eat, which makes Du Jianguo appreciate it very much. Du Jianguo believes that real friends do not invite each other to dinner, but go to each other's restaurants to eat and insist on paying the bill. Another thing that Du Jianguo admires about Wang Qianyuan is that Wang Qianyuan has a good brain, speaks fun, and can often think of some ideas that he can't think of. Du Jianguo has rented and sold barbecue, and he has seen a lot of people, but most of them are not interesting, what they think is just a little trivial in front of them, and the chatter is all clichés. Sometimes as soon as the other party opens his mouth, you know what he is going to say, what else is there to talk about? But Wang Qianyuan is different, this guy always talks out of the blue, and sometimes you don't know what he wants to say after talking.

Wang Qianyuan lived in a courtyard with Du Jianguo when he was a child, and he had a lot of ideas since he was a child, and he led the children to be naughty and mischievous. When I grew up, I was much more honest, and I was polite to everyone. Wang Qianyuan's university majors are traditional medicine from various countries, such as Chinese traditional medicine, Ayurveda in India, the four-humor theory in Europe, witch doctors in Africa, and other pseudo-sciences. After graduation, Wang Qianyuan began to sell health care products, and his main customers were middle-aged and elderly people, and it seemed that the business was not bad. ”

Wang Xijia read this page inexplicably, and his mind was full of questions: This seems to be the beginning of a novel, and the technology in the novel seems to be more developed than the 2060 he has traveled through, has human beings really experienced several rounds of civilization, among which the civilization of Atlantis is more advanced than the civilization of later generations?
