In the real world, in the crossing square of the underground base, Dong Chen stepped out of the blue circular arc door in one step, this time he came back alone, without driving or bringing a robot, only a mobile hard drive full of new information.

When he was alone, he was still in a very safe place, and Dong Chen still preferred to use the visible blue arc gate, because that was his first impression of the crossing gate.

For any living being, the first impression is quite important, this is the imprint learning in animal behavior, many birds and mammals have this behavior, simply put, the first living creature seen at birth is called the mother.

It doesn't even matter if it's a living thing, as long as it's a moving, larger object.

This is determined by evolutionary selection and is an important form of learning for newborn animals, which allows these defenseless critters to cling to their parents, thus making food supplies and shelter requirements more secure.

Although human beings can already serve a lot of biological instincts, they won't be so extreme, and they will understand when they grow up and become sensible, but the first impression is also quite important, and it can be used in finding a job, making friends, shopping and daily life.

"Welcome back, sir."

This was the first sentence Dong Chen heard after he walked out of the arc gate, and it was also the first sentence he heard every time he came out.

"Well, long time no see."

After greeting No. 1, Dong Chen noticed that it was quiet across the square, and even the nearby corridor was no longer busy with robots coming and going.

"Hey, No. 1, those machines ......," Dong Chen said halfway through and suddenly patted his still bright head, "Oh, by the way, the base has all been built and renovated, right?" ”

"Yes, sir, the base has been completely renovated, do you need me to take you around? They're very different from before you left. ”

No. 1 invited Dong Chen, and an electric car had already driven over, and some of Dong Chen's preferences and habits were clearly known.

"Of course." Dong Chen readily agreed.

Sitting on the electric car that drove over from No. 1, Dong Chen began his journey to the base, starting from crossing the square, the corridors were empty, but the relative mess was gone, such as scaffolding, auxiliary pipelines, etc., which looked very neat and tidy.

In the labs where there were not many things, the original exposed cables and pipes were replaced by corresponding instruments, and various mechanical equipment and scientific instruments filled those empty places, making each laboratory look like a scene from a science fiction movie.

In fact, it is not what it looks like, but something that is only found in real science fiction scenes, and most of the things in science fiction films are an advanced science fantasy, or a speculative earth that will look like in tens or hundreds of years.

The laboratory installations here are decades and hundreds of years higher than the current state of the art, and for those outside the base, this is not the scene of a science fiction movie.

When the car reached the industrial zone, it stopped, because Dong Chen saw the robots that were no longer wandering around, they were being transformed, removing some of the mechanical devices, and then installing other different mechanical devices.

Dong Chen watched a robotic arm with a needle-like device being mounted on a wheeled robot, and several sets of electrically driven pulleys were also installed on this robot, so he asked curiously, "That robotic arm is electric welding, right?" Are the electrically driven pulleys on top of them to move them on the scaffold? ”

"Yes, sir, our next plan to build a ship is to weld the hull with electric welding, and this robot is to move on the scaffolding outside the hull, and installing pulleys will allow them to move their positions more efficiently." Number One said.

"Well, the number of these robots is enough, should we increase the number of robots, and when the design of the submarine is determined, we will build it as quickly as possible." Dong Chen thought for a while and gave No. 1 a reference, "With these robots, how long will it take us to build a 100,000-ton aircraft carrier?" ”

After listening to Dong Chen's question, No. 1 gave the answer without hesitation, "Sir, to build a 100,000-ton aircraft carrier, we only need 64 to 70 days to complete, we now have 1,700 robots of various types, we don't need to use 100% of the number of robots, only 78% of the number of robots can reach the maximum speed, and more of them will reduce the speed to a certain extent." ”

"Oh, so fast? In just over two months, we can build an aircraft carrier? ”

Getting this answer, Dong Chen was indeed quite surprised, although this base was built very quickly, and it took less than three months to complete, but the difficulty of building and aircraft carrier construction is not the same, I didn't expect to build an aircraft carrier so quickly.

"Yes, sir, we have more advanced manufacturing technology, which can greatly increase the speed of construction, and the speed and precision of robots are not comparable to that of human workers, and robots can work 24 hours a day."

"The technology of our robots is also very advanced, and the failure rate is very low, and only 32 robots have failed during the construction of the base. And it is understood that the construction process of the aircraft carrier needs to be responsible for many parties, and it is not excluded that these non-construction reasons will slow down the progress, and we only need to be responsible for you. ”

After saying that, Number One seemed to pause for a few seconds, then added, "And you're okay 95% of the time." ”

Belch...... Although I think it's weird, I always feel despised by artificial intelligence.

However, Dong Chen couldn't get angry with an "ignorant" artificial intelligence, and after knowing that the robots were building ships soon, he let No. 1 drive the car and continue to move forward.

Away from the busy industrial area, this is already very close to the docks, and after a few turns to the docks, this is also another busy place.

The Yangtze River No. 31 submarine has been transferred to the dock, there are a large number of robots working on it, the original complete and mighty submarine has disappeared, the entire submarine has been dismantled, many shells have been cut off, through the gap you can see that most of the internal instruments of the submarine are gone, only empty shelves remain.

The dismantled equipment and hulls are reduced to raw materials and piled up in the material warehouse after a series of advanced recycling procedures, waiting to be taken out and used again.

After staying here for a while, Dong Chen set off again, until the electric trolley turned all the places, and finally drove to the door of Dong Chen's special laboratory.

It's said to be a laboratory, but it's actually a replica of the above-ground dwelling, with bedrooms, dining rooms, kitchens, and a small private experimental equipment, but the level of technology here is much higher than on the ground.

Dong Chen came to the workbench and connected the mobile hard drive he brought back to the data interface, so that No. 1 began to transfer data.

Looking at the data sorted out by No. 1, Dong Chen suddenly remembered the replacement plan that No. 1 said before, so he asked, "By the way, the information I gave you before, how many equipment in the base can be upgraded and optimized after the sorting is completed?" ”

"Sir, that's right, after sorting out the information you brought back, 35% of the equipment in the base can be updated, of which 12% of the equipment needs to be completely replaced and upgraded, and 23% of the equipment can be optimized and upgraded by replacing parts or adding new modules."

"After the equipment in the base is upgraded, the scientific research capacity is expected to increase by 23%~25%, the manufacturing capacity is expected to increase by 17%~18%, the internal weapon defense capability is expected to increase by 9%~12%, and the wall defense is ...... It is expected to improve the ......, the non-slip ...... of the floor, and the fresh air ......"

"Stop," the front was fine, but when he heard Dong Chen behind him, he hurriedly shouted to stop, "What are you behind here, and the floor is non-slip, why don't you go to the sky." ”
