"How is it? I haven't performed for a long time, so I'm a little nervous."

The lighting in the ecological park was restored, and Lin came in front of the four people. Her expression seemed a little shy, which was an emotion that was difficult for a robot to show.

"very nice."

Lu Ban commented.

"What's wrong with you?"

Lin looked at the other three people. The expressions of the three of them were a little gloomy. The glorious history and the bleak present formed a sharp contrast, which made people feel deeply moved.

Having witnessed such a powerful past being destroyed by disaster, how can people today resist the swarm?

Despair and powerlessness enveloped them.

"If you feel unwell, I can provide some medical supplies. I'm sorry, but our medical robot has stopped working."

Lin said helplessly.

"By the way, is there any place like an industrial park nearby? Is that where the people in Future City used to work?"

Lu Ban asked hurriedly.

"As for the industrial park, it's seven kilometers north of here, but unfortunately, the connection with the industrial park has been cut off. If we can try to contact them, they can send a vehicle to pick us up..."

Lin tilted her head and said this again, and Lu Ban suspected that her action was actually an attempt to make contact.

But there is no doubt that in this destroyed world, the communication is just a cacophony of noise.

"The power supply is there too, right?"

Lu Ban interrupted Lin's attempt to communicate.

"Yes."

The robot girl nodded and said with some embarrassment.

"It's just that we can't leave Future City, so we didn't try to go over and check the situation. Maybe the residents are staying there."

"Do you have the information there? Electronic or paper will do."

Seeing Lin nodded in confusion, Lu Ban continued.

"Help us find it, and we'll go over there tomorrow to check if the power can be restored."

After hearing Lu Ban's words, Lin showed an expression of surprise that might belong to a robot.

Then she nodded vigorously again.

"OK!"

…

There is not much information left in the Future City. Since it is an industrial park for scientific research, it must involve many secrets.

Not to mention the condition of the laboratory, there is not even the layout of the power system, only a rough diagram of the building complex.

Maybe this is to prevent something from finding the power facilities and destroying them.

Thinking about this, Lu Ban became curious about how the previous civilization in the wasteland was destroyed.

Lu Ban learned from most of the indigenous people that due to the prevalence of crystal disease, the life expectancy of patients with crystal disease is indeed not long.

But is this really the case?

Whether it is the tightening quality of life, or this ecological park, the industrial park next door, or the research on the universe, they all suggest that the world is facing a greater crisis, and if human beings cannot find a way to save themselves within a period of time, they will be destroyed.

In the end, they didn't find it.

At night, the three natives of the wilderness chose to sleep in the ecological park.

For them, such an environment is precious.

Lu Ban was not asleep. He went to a bench for resting and gazed at the starry sky.

Lin came to his side. The robot girl seemed to be resting here. In any case, as the housekeeper here, her battery would definitely be the last to run out, which meant that in the future, she would definitely be the last robot to lose consciousness.

She will send away all her companions and finally fall asleep in a long and eternal sleep.

"Guest, are you unable to sleep? I have 3,722 bedtime stories and lullabies. If you need, I can tell them to you."

Lin said as if she was ready to coax a child.

"No, I'm used to going to bed late."

Lu Ban answered.

"Can I sit down?"

After getting Lu Ban's consent, Lin sat at the other end of the bench.

Her bare feet tapped rhythmically on the artificial grass.

"Actually, I'm really glad you guys can come."

Lin also looked at the starry sky and spoke softly.

"During this period of time, all the robots in the Future City held 2,147,483,647 discussions. All the robots believed that humans would never come back, except for me."

"They believe that humans have successfully left this planet and gone to a new home, but we were created to serve humans and don't know how to act after humans are gone."

"But I believe that humans will definitely come back."

"Meeting you guys proves that I was right."

After hearing Lin's words, Lu Ban suddenly wondered whether the robots in this world had awakened a certain degree of self-awareness?

"In fact, you don't have to follow humans. Robots can take care of themselves."

He said.

"No, this is already written into our program. In our basic framework, or in human terms, this oath has been engraved in our souls. We were born for humanity."

Lin was very determined. This seemingly weak robot girl would be as hard as steel only when it came to these things.

"Then you can come with us then. We are human beings anyway."

Lu Ban added that there was no way to follow him, as the foreign land should not be able to carry so many robots back to his world. Instead, they could let these robots follow Shuang Xin back to Utopia. Perhaps the saints there could find a way to keep these robots moving.

"This... I need to check the response manual. This is something that has not appeared in the manual yet."

Lin was a little surprised, a little confused, and a little at a loss.

"Think about it carefully, and you can give us the answer when we come back tomorrow."

Lu Ban touched the other person's head.

Artificial hair looks so real.

He sighed inwardly.

…

Early in the morning, before daybreak, the four of them left the ecological park, took the map, rode on camel worms, and headed towards the location of the industrial park.

Lu Ban saw Lin standing at the entrance of the ecological park, bending down to see them off, and did not stand up until she disappeared from his sight.

Seven kilometers is not far.

At noon, when the sun was at its hottest, Lu Ban saw a strange object outside the desert.

"What's this?"

Frost Heart slightly blocked out the sunlight and observed carefully.

It was a tall and huge shelf. Something should have been placed on it, but there was nothing on it.

Next to the shelves, there are rows of buildings in different shapes.

Spreading outward from this point is a group of damaged buildings.

This must be the industrial park.

Lu Ban observed carefully but found no trace of the swarm of insects.

"Shall we go in and explore?"

Frostheart asked uncertainly.

"It's still the same as before. Shuangxin and I will go."

Lu Ban was a little worried, but decided to lead the way.
