Chen Xu's long silence attracted Taichu's question, "You seem unhappy."

"It's not that I'm unhappy." He sighed softly, "I just feel that humans will actually fall to this level, which is a bit sad."

Taichu seemed to like discussing such topics and said, "I don't understand why you feel like this. If the race continues, isn't it the first priority? Naturally, you have to choose the most efficient approach."

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

After all, he subconsciously only regarded this as a game. He could not truly take into account the current role, so he could not consider the issue from the current standpoint.

He may be the last human in this world. From a pragmatic perspective, Taichu's method is the most efficient. In just one year, more than a thousand adult humans who can do ordinary jobs can be added. Regardless of whether they are ripened or not, they are all members of human beings.

When several groups of such humans come out and have a base, they can slow down and cultivate real elites. Perhaps in less than ten years, the human race will be revived.

If according to the normal growth rate of humans, ten years will only be enough to grow to the excessive stage of children and adolescents. That would be too slow and it may take hundreds of years to reproduce to a certain number.

When Chen Xu thought of this, he suddenly understood why his previous career was half-dead. Because he had too many concerns and too strong self-esteem, he was unwilling to use many methods, which greatly restricted his way of doing things.

People like Liu Kun can stand up for airs and be able to put their composure. They are trustworthy when they should be trustworthy, and they turn against each other when they say they are unscrupulous and have very flexible skills in doing things.

A few minutes later, Taichu asked him, "What are you thinking?"

He said, "I'm thinking about how to make money faster."

Taichu said, "Human thinking is sometimes really jumpy and has no logic."

Chen Xu stood up and took a pack of nutritious meals from the refrigerator. He didn't look at the taste. After unscrewing it, he took a bite. His face froze, and it turned out to be durian-flavored.

He pinched his nose and finished a pack of nutritious meals. As he ate, he unexpectedly felt that it was quite delicious, but it was not unacceptable.

It really smells smelling and tastes delicious.

I don’t know what kind of experience it is if I don’t try some things.

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

"It has been uploaded to your personal account."

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

This is the direction he chose to learn, which includes both theoretical knowledge and practical skills. It is very practical in both dreams and reality.

One hour of study time is only enough for him to learn a small part of it. As long as he can master this knowledge, his speed of making money can be greatly improved.

However, Taichu reminded him that the most important thing in learning maintenance is practical exercises, which requires a lot of practice. Let him consider it carefully.

He did not explain much about this issue. For him, as long as it is a skill that uses hands, it doesn't take too much time to learn it.

He opened the book and began to review.

…………

Three days later, Chen Xu passed the system exam and obtained the title of a first-class communication engineer. He could move to C1 to live.

Area C1 and Area C2 are very different. The room is twice as big as it is, and there is an independent bathroom. Even the food standards have become high-end nutritious meals, from bags to bottles.

The job he could choose also changed from a maximum hourly salary of 150 credit points to a maximum hourly salary of 300 credit points, which doubled. The maximum income of a day reached 5400 credit points.

The actual work content has not changed at all, so it is better to clear the sewer.

The same job, just because his level has increased, his salary has doubled. There is no reason to say, Taichu explained that this is a regulation.

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

Taichu told him that using a learning machine will cause minor damage to the brain. Every time you use it, it will take a certain time interval. The second time is ten days, and the third time is twenty days. This is a mandatory regulation.

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

After eleven days, he lay in the learning machine again and received the second indoctrination of knowledge. This time, the lasting time was 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 maintenance cases, he can take the exam for an intermediate communication engineer. Once he passes, he can be promoted to level B and has higher authority.

…………

Just as Chen Xu was working hard for the goal of an intermediate communication engineer, Yang Jinxia brought her robot army to the tide of strange beasts that were rushing towards him.

She sat upright in the air, staring at the screen, and the scene taken from the perspective of the plane in the sky was seen as densely popping up the sky and rushing towards her like a tide.

Compared with this huge beast tide, her convoy was as small as a stream.

"Give up the vehicle, the troops gather."

She looked cold and said commands from her mouth, "Aircraft, bombing opens the way."

"The attacker forms arrows. The hunter follows closely, and the S-level robot guards me and rushes."

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

When the two sides were about to contact, the planes in the sky began to bomb. They did not use powerful cannons/amps, but large grenades equipped with steel balls. The main purpose was to kill. If a bomb fell, a large area of ​​strange beasts fell.

From the perspective of the sky, the number of strange beasts that are about to come into contact with the robot has become rare at a speed visible to the naked eye.

Immediately afterwards, it collided violently like Mars hitting the Earth.

In a very short time, Yang Jinxia's stream went upstream and was surrounded by the beast tide. Countless strange beasts pounced on it, almost submerging her army.

Her eyes were quiet, and she ordered the S-level robot guarding her side to go forward to make up for the seats. As for the engineering robots that were dragged by a strange beast in the back and could not keep up with the large army, she didn't care at all.

The screen in front of her was showing the number of robots. In just over a dozen minutes, it dropped sharply from six digits to five digits, ninety thousand, eighty thousand, and seventy thousand...

Even if the number dropped to 10,000, her eyes still remained unchanged.

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

Kill out!

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

She pointed in that direction and said, "Run over."

The only thousands of robots left were sprinting in that direction quickly.

Behind him, the still dense tide of beasts turned around and followed from behind. However, how could the flesh and blood body run better than the robot powered by a super battery? It was thrown farther and farther away.

Some particularly huge beasts made anxious roars.

More than ten minutes later, Yang Jinxia's robot army had arrived in front of the black vortex, and saw strange beasts struggling and rushing out of the vortex and being shot and killed by the robot one by one.

She finally asked her subordinates to stop and clicked a name, "s12, go in."

A robot came out, pulled a steel cable, and rushed into the vortex quickly.

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

She ordered, "pull it out."

A robot pulled the steel cable back, and after a while, he dragged the s12 out. It lay down on the ground, and the indicator light on its body had turned off.

Yang Jinxia said, "Restart."

After a while, the light in s12's eyes lit up.

A smile appeared on her face, and opportunities were always left to those who were prepared. After using the electromagnetic pulse gun to kill S01, she took into account the weakness of the robot and added an overload protection device. Now it seems that the effect is good.

After such delays, the tide of strange beasts behind us has approached.

"Let's go in." She rushed into the vortex with all the robots and disappeared soon.
Chapter completed!
