Chen Xu's long silence aroused Taichu's question, "You don't seem very happy."

“It’s not that I’m unhappy.” He sighed softly, “I just think it’s a bit sad that humans have fallen to this level.”

Taichu seemed to enjoy discussing such topics and said, "I don't understand why you feel this way. Isn't the continuation of the race the top priority? Naturally, we should choose the most efficient method."

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

In the final analysis, he subconsciously only regarded this as a game. He could not really put himself in the current role, and therefore could not consider the problem from the current standpoint.

He might be the last human being in this world. From a pragmatic point of view, Taichu's method is the most efficient. It only takes one year to produce more than a thousand adult humans who can do ordinary jobs. Regardless of whether they are accelerated or not, they are all human beings.

When there are several batches of such humans and a base number, we can slow down the pace and cultivate real elites. Perhaps within ten years, the human race will regain its vitality.

If we follow the normal growth rate of humans, ten years is only enough for them to grow to the transition stage from children to teenagers. That is 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 had been half-dead. Because he had too many concerns and too strong self-esteem, he was unwilling to use many means, which greatly restricted the way he did things.

People like Liu Kun can hold themselves up to their dignity but also put aside their pride. They can keep their word when necessary and can turn against it at any time without any scruples. They are very flexible in doing things.

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

He said, “I’m thinking about how to make money faster.”

Taichu said, "Sometimes human thinking is really jumpy and has no logic at all."

Chen Xu stood up and took a pack of nutritious meal from the refrigerator without even looking at the flavor. He unscrewed it and took a bite. His face froze. It tasted like durian.

He pinched his nose and finished the whole packet of nutritious meal. As he ate, he found it surprisingly delicious and it was not unacceptable.

It actually smells bad but tastes good.

There are some things that you really don’t know what it’s like if you don’t try them.

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

"It has been uploaded to your personal account."

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

This is the direction he chose to study, which contains both theoretical knowledge and practical skills. It is very practical whether in dreams or in 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, the speed at which he makes money can be greatly improved.

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

He did not explain much about this question. To him, as long as it was a skill that required hand operation, it would not take much effort to learn.

He opened the book and began to review.

…………

Three days later, Chen Xu passed the system's exam and was awarded the title of a first-level communications engineer, and was able to move to Area C1.

There is a huge difference between Area C1 and Area C2. The rooms are twice as big and have an additional independent bathroom. Even the food standards have become high-end nutritious meals, which are packaged in bottles instead of bags.

The jobs he could choose also doubled their hourly wages from 150 credit points to 300 credit points. His highest daily income reached 5,400 credit points.

The actual work content has not changed at all, it is still unclogging the sewers.

For the same job, his salary doubled just because his rank was promoted. This made no sense at all. Taichu explained that this was the rule.

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

Taichu told him that using a learning machine would cause slight damage to the brain, and that there should be a certain amount of time between each use. The second time should be ten days, and the third time should be twenty days. This was a mandatory rule.

The more times you use it, the longer the intervals should be. Otherwise, it is easy to cause irreversible damage to the brain.

Eleven days later, he once again lay in the learning machine to receive the second knowledge indoctrination. This time, it lasted for four hours, enough for him to memorize the entire content of "Basics of Wireless Communication Equipment Maintenance".

By then, as long as he has accumulated enough successful maintenance cases, he can take the intermediate communication engineer exam. Once he passes, he can be promoted to level B and have higher authority.

Just as Chen Xu was working towards the goal of becoming an intermediate communications engineer, Yang Jinxia led her army of robots to meet the oncoming tide of alien beasts.

She sat upright in the air, staring at the screen. The scene captured from the perspective of the plane in the sky showed dense swarms of strange beasts, overwhelming and surging like a tide.

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

"Abandon the vehicle and assemble the troops."

Her expression was stern as she spoke out orders one after another, "Aircraft, bomb and clear the way."

"The attackers will form the spearhead. The hunters will follow closely behind. The S-class robots will guard around me. Charge."

Following 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 come into contact, the planes in the sky began to bomb. They did not use high-powered cannons/bombs, but large grenades loaded with steel balls. Their main purpose was to kill. When a bomb fell, a large number of monsters fell down.

Seen from the sky, at the location where the robot was about to come into contact, the number of strange beasts was becoming scarce at a speed visible to the naked eye.

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

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

She looked calm, and from time to time she ordered the S-class robots guarding her to move forward to fill in. As for the engineering robots in the rear that were being held back by the alien beasts and could not keep up with the main force, she didn't care at all.

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

Even when the number dropped to ten thousand, her gaze remained unchanged.

Just when the S-class robots around her were almost used up, the pressure in front of her suddenly disappeared, and the view in front of her instantly became extremely open.

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

She pointed in that direction and said, "Go ahead."

The few thousand remaining robots rushed towards that direction at a rapid speed.

Behind him, the still densely packed beasts changed direction and followed from behind. But how could flesh and blood outrun a robot powered by a super-powered battery? They were left further and further behind.

Some particularly huge beasts let out anxious roars.

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 were shot dead by the robots one by one.

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

A robot came out in response, pulling a steel cable and rushing into the whirlpool quickly.

The number of robots on the screen in front of her suddenly decreased by one.

She ordered, "Pull it out."

A robot pulled back the cable, and after a while, it came out dragging S12. It lay on the ground with its indicator light off.

Yang Jinxia said, "Restart."

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

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

As a result of this delay, the tide of strange beasts behind them was already approaching.

"Let's go in." She rushed into the whirlpool with all the important robots and soon disappeared.
