Chen Xu's long silence caused Taichu's question, "You don't seem to be very happy." ”

"It's not that I'm unhappy." He sighed softly, "I just think it's a little sad that human beings have actually fallen/fallen to this extent." ”

Taichu seemed to like to discuss such topics, saying, "I don't understand why you feel this way, isn't it the first thing that the race continues?" Naturally, choose the most efficient approach. ”

Chen Xu had to admit that it was right. In the face of life and death, it is superfluous to consider these things.

In the end, he subconsciously just regarded this as a game. If you can't really take on the role of your current role, you can't think about it from the standpoint of the moment.

He may be the last human in this world, and from a pragmatic point of view, the original method is the most efficient, and it only takes one year to produce more than a thousand more adult humans who can do ordinary work. Whether they are ripe or not, they are all members of the human race.

When several batches of such humans come out, and there is a base, it is possible to slow down the pace and cultivate a true elite. It may not take ten years for the human race to regain its vitality.

If we follow the normal growth rate of human beings, ten years is only enough to grow to the transition stage from childhood to adolescence. That's too slow, and it can take hundreds of years to reproduce to a certain number.

Thinking of this, Chen Xu suddenly understood why his previous career had been half-dead. Because he has too many scruples and too strong self-esteem, he is unwilling to use many means, which greatly limits the way he does things.

People like Liu Kun can stand up to the shelf, and they can also put their heads down, talk about credit when it's time to talk about credit, turn their faces when they say they turn their faces, they have no scruples, and their skills are very flexible.

After a few minutes, Taichu asked him, "What are you thinking?" ”

"I'm thinking about how I can make money faster," he said. ”

Taichu said, "The human mind is sometimes really jumpy, and there is no logic at all. ”

Chen Xu stood up, took a pack of nutritious meals from the refrigerator, didn't see any flavors, unscrewed it and took a bite, his face stiffened, it was actually durian-flavored.

He pinched his nose and finished a pack of nutritious meals, eating and eating, and unexpectedly felt quite fragrant, not unacceptable.

It really smells bad and tastes good.

There are some things that I don't really know what kind of experience it is if I don't try them.

He picked up the cup, poured another glass of water, drank it, sat for a while, gradually regained some strength, and said, "Please send me the knowledge I need." ”

"It's been uploaded to your personal account."

Chen Xu clicked from a certain position on the wall, a screen appeared on the wall, he clicked on his personal account, opened the bookshelf, and there was a book in it, "Basics of Wireless Communication Equipment Maintenance".

This is the direction he chooses to study, which has both theoretical knowledge and practical skills. Whether in dreams or in reality, it is very practical.

An hour of study time is only enough for him to learn a small part of it. As long as he can master this knowledge, the speed at which he can make money can be greatly improved.

However, Taichu reminded him that the most important thing to learn maintenance is practice, which requires a lot of practice. Let him think carefully.

He didn't explain much about this problem, as long as it was a skill to operate by hand, it didn't take too much effort for him to learn.

He opened the book and began to review.

…………

Three days later, Chen Xu passed the systematic exam and won the title of a first-class communication engineer. It is possible to move to C1 to live.

The C1 area is very different from the C2 area, the room is twice the size, there is also a separate/independent bathroom, and even the food standard has become a high-end nutritious meal, from bagged to bottled.

The job he was able to choose also doubled from the highest hourly wage of 150 credit points to the highest hourly salary of 300 credit points. The highest income in a day reached 5,400 credits.

The actual work content, in fact, has not changed at all, it is still to unclog the sewers.

For the same job, simply because his rank was raised, the salary was doubled. There is no reason to talk about it at all, too early to explain, this is the rule.

This time, Chen Xu worked for eight days and saved up 40,000 credits before going to the learning base and using the learning machine again.

Taichu told him that using the learning machine would cause slight damage to the brain, and each time he used it, he had to wait a certain amount of time. The second time is ten days apart, and the third time is twenty days apart. This is mandatory.

The more you use it, the longer the interval will be. Otherwise, it is easy to cause irreversible damage to the brain.

After eleven days, he lay down in the learning machine again and received a second indoctrination. This time, it lasted for four hours, which was enough to memorize the entire content of "Basics of Wireless Communication Equipment Maintenance".

At that time, as long as he accumulates enough successful cases of maintenance practice, he can go to the intermediate communication engineer examination. Once passed, you can be promoted to B level and have higher permissions.

…………

Just when Chen Xu was working hard for the goal of an intermediate communication engineer, Yang Jinxia led her robot army to meet the tide of strange beasts that rushed wildly.

She sat in the air, staring at the screen, and took the scene from the perspective of an airplane in the sky, only to see a dense crowd of strange beasts rushing to the sky, surging like a tide.

Her convoy was as small as a stream compared to the massive tide of beasts.

"Abandon the vehicles and assemble the troops."

Her expression was grim, and one command after another came out of her mouth, "Aircraft, bomb and open the way." ”

"Attackers form arrows. The hunter followed, and the S-class droids arched around me, rushing. ”

With her order, the robots in the convoy quickly moved into action, formed a formation, and rushed towards the beast tide.

When the two sides were about to make contact, the planes in the sky began to bomb, using not high-powered cannons/shells, but large grenades loaded with steel balls, with the main purpose of killing and injuring.

From the perspective of the sky, the number of strange beasts at the point where it is about to come into contact with the robot is becoming scarce at a rate visible to the naked eye.

Immediately afterward, there was a violent collision like Mars hitting the Earth.

Yang Jinxia's stream, in a very short period of time, went upstream, and was completely surrounded by the beast tide, and countless strange beasts pounced on it, almost drowning her army.

Her eyes were calm, and from time to time she ordered Gong Wei to step forward to fill in the S-class robots beside her. As for the engineering robots that were dragged by strange beasts in the rear and couldn't keep up with the large army, she didn't care.

The screen in front of her showed the number of robots. In just ten minutes, it has dropped sharply from six figures to five figures, 90,000, 80,000, and 70,000......

Even though the number dropped to 10,000, her gaze remained unchanged.

Just when the S-class robot beside her was almost exhausted, the pressure in front of her suddenly ran out, and her eyes instantly became extremely open.

It's out!

She looked into the distance, where there was something like a black swirl.

She pointed in that direction and said, "Rush over." ”

The few thousand robots that were left were sprinting in that direction at a rapid pace.

Behind him, the beast tide, which was still dense, turned around and followed from behind. However, how can flesh and blood outrun a super battery-powered robot? Thrown farther and farther away.

Some of the most huge beasts let out anxious roars.

Ten minutes later, Yang Jinxia's robot army had already arrived in front of the black whirlpool, only to see a strange beast struggling and rushing out of the whirlpool. Shot one by one by robots.

She finally stopped her subordinates and called a name, "S12, go in." ”

A robot came out in response, pulled a steel cable, and rushed into the whirlpool with great speed.

On the screen in front of her, the number of robots suddenly decreased by one.

She ordered, "Pull it out." ”

A robot pulled back the steel cable, and after a while, dragged the S12 out, and it lay on the ground, the indicator light on its body had been extinguished.

Yang Jinxia said, "Restart." ”

After a while, the light in S12's eyes lit up.

There was a hint of a smile on her face, and opportunities are always reserved for those who are prepared. After using the EMP gun to kill S01, she took this weakness of the robot into account and added an overload protection device. Now it seems that it worked well.

After such a delay, the tide of strange beasts behind has already caught up.

"Let's go, let's go in." She took all the key robots with her and rushed into the whirlpool, quickly disappearing.

PS: I still remember the addition, don't worry. Finally, ask for a monthly pass.
