In the summer of 2912, the news was playing that the Siberian tiger had used genetic technology to return to the ranks of creatures.

On the 140th floor, two mechanical bodies reflect the afterglow of the setting sun, and their bodies are covered with a metallic sheen.

"Did you see the news?" Wu Yuanxing put away the three-dimensional information board in his arm.

Mu Yan didn't speak, just looked down at the woman pattern on his arm.

This caught Wu Yuanxing's attention, and he came up and asked, "Couple in the period of living organisms?" ”

"My mom." Mu Yan replied lightly.

"Anyway, we've known each other for more than two hundred years, haven't we seen your parents, and haven't we undergone mechanical transformation?" Wu Yuanxing asked.

"Yes, my parents committed suicide before receiving mechanical body transformation, their last words were that if you can't kiss lightly, you can't see the joy, anger and sorrow on your lover's face, you won't be alive, I was 19 years old at the time, in fact, I understand, I just don't understand why I want to give up eternal life, but I understand now." Mu Yan lowered his head and looked at the pattern sprayed on his arm, and the high-density screen simulated his eyes, but he no longer had the dazzling sense of sunlight, and he could no longer shed tears.

"Love is a relic of the old times, and it's good now, there is no war, I'm quite looking forward to the next trip," Wu Yuanxing lowered his head and swung his newly equipped air compression gun, which was the spoils of war purchased with the money reward he received from his last trip to the Sahara rainforest.

"Isn't it time for us to go back to Whale Back," Mu Yan said, "It's been three hours since I came out." ”

Whale spine is the residence of human beings in the sea in the mechanical era, at the beginning of the mechanical body transformation, the country has been canceled, the important leaders of the countries in the era of organisms jointly established the world coalition government, in order to ensure the normal development of human beings in the mechanical era, the world coalition government established the "green land law", according to the order of the mechanical body will be divided into three categories of human beings, the first to carry out the mechanical transformation of the political leaders of various countries and people with absolute power and financial resources, this part of the people live in high-rise buildings, called eagle shoulders, The second part is the whale spine, and the people living inside are the last people to be modified by the machine. There is no hierarchy of the three parts of the people, with the development of history, the members of the eagle shoulders have gradually evolved to be composed of outstanding people, and the people of the current world have absolute respect for the first part of the people who lead mankind forward, and cooperate with the protection of the earth's climate and the maintenance of biodiversity.

"Yes, if you don't go back, you'll be scolded." With that, the two of them jumped and glided in the air, their eyes full of the light reflected by the tall buildings and the green trees and flowers.

Fortunately, they didn't miss the time for evening practice, and the two staggered back to the team, just in time to bump into Captain Sun.

Captain Sun looked at the two of them coldly, "Let's run out again", the jet code on the shoulder is a symbol of Captain Sun's identity, the jet code is a person's ID card in the mechanical era, which will record the person's outstanding contribution to the mechanical era, and Captain Sun's shoulder has 130 travel records.

The four soccer field-sized training fields are the training grounds for the Expedition team, and the huge screens overhead and around them simulate the dynamic weather on the ground, making the ocean indistinguishable from the ground.

After the disbandment, the two got together again, "130 long-distance travel records, Captain Sun is too powerful." ”

"Many people join the expedition team because of their admiration for Captain Sun." Mu Yan said lightly.

"What about you?"

"I just want to go out and have a look."

"I said you've been like this for a while, can you not be sentimental, more than three hundred years ago, 99% of the votes passed the human machine, there is no need to imitate the human body on the current mechanical body, the structure of the human fur has already shown our determination to open a new era of mankind, so hundreds of years, even love has been gradually abandoned by people, isn't the meaning of life the continuation of thought? You've been wondering lately, what the hell is going on? ”

At the beginning of the construction of the undersea city, in order to avoid the pressure of the sea water from increasing the burden of the city, the whale spine was divided into more than a hundred cities, each city is connected by at least two kilometers of tunnels, each city lives millions of people, and above the tunnel is a screen of about one hundred and fifty square meters, which plays the news that is happening in this world every day, and the lower left of the screen records the current number of human beings.

"Eighty eight million three hundred seventy six thousand two hundred and seventy-one." Wu Yuanxing looked up, "There are more than 100 fewer people than yesterday." ”

Mu Yan looked down at the display screen of his arm, and was immediately stopped by Wu Yuanxing.

"I said you're almost there?" Wu Yuanxing roared: "If you want to die, I won't stop you, but you can also see how much money you have." ”

Money has always been an item to maintain the normal activities of human beings, there is a demand for money transactions, and the world coalition government in order to prevent the decline of the population, there are strict restrictions on death, the "Green Land Law" contains death licensing regulations are very complex, in the era of mechanical bodies, the final erasure of data is for the death of a person, and the cost of complete erasure of data is 300 times the current average annual income of human beings in the world, and it can not cost a penny in three hundred years, that is, Death in the Age of Machines is strictly restricted. If a person's mechanical body is unusable, the "recasting" department will activate the person on the new mechanical body, and the activation method is divided into two methods, if the chip in the data storage area of the head of the original mechanical body is not damaged, the chip will be transplanted, and if it dies, the data will be backed up from the Eagle Shoulder Data Storage Center, this method will make the mechanical body lose all the data stored so far, that is, "memory", and the process of reactivation needs to recover all the funds of the target person as the price of reactivation.

"yes, death is restricted, why don't you go to the tunnel with me at three o'clock in the morning?" Mu Yan said.

"Miss your baby dolphin again?"

"Well, I'll see you at the tunnel door then." Mu Yan said, found a charging pile, paid some money and "fell asleep." ”

The architecture of Whale Ridge is generally low, and as in the age of living organisms, many people also own houses, and the housing prices are expensive, but for Muyan, it is not necessary, it seems that human beings have abandoned the past life and rest, and there is no need to rest 24 hours a day, but entertainment places abound, and it seems to be a paradox.

At three o'clock in the morning, the two gathered at the mouth of the tunnel, as the only place where they could see the underwater world in the ocean, Mu Yan liked it very much.

The two of them waited quietly for the dolphins in the tunnel, the dolphin such as Mu Yan is the seventh generation of the dolphin named Yu An, unlike other dolphins, Yu An and his spouse practice monogamy, which has continued to this day, Mu Yan welcomes the new generation and sends away the old generation.

"It's been more than half an hour, will it not come?" Wu Yuanxing wondered.

"It's coming." Mu Yan said firmly.

After a while, three black shadows appeared not far away, two large and one small, swimming towards the tunnel, and the "heart" that Mu Yan was carrying settled down.

The two dolphins touched their mouths and looked at each other, Mu Yan put his hand on the tunnel wall, and the three dolphins also put their mouths up, looking at each other through the transparent wall, this is a fixed meeting at four o'clock in the morning every Tuesday, and it is also the time when Mu Yan yearns for life the most.

Wu Yuanxing watched quietly, and seemed to understand Mu Yan's mind a little.

"Do you remember the feeling of breathing?" Mu Yan suddenly turned his head to look at Wu Yuanxing.

"Breathe?"

Will we still breathe?
