The underground shelter residential area had been carefully explored by Xu Ran and the robot, and there was no other hidden area to be discovered except for the powerful area that was separately demarcated.

As for the exploration of the underground factory, every time he can find something new, this makes Xu Ran feel a little strange.

The first time he entered the Fragmented City was he began to focus on collecting all the paper materials and books, not even a fragment of a newspaper with handwriting, and a handwritten note.

However, after discovering the underground shelter and the underground factory, he has been focusing on finding the blueprints for the two underground facilities.

However, neither the robot storage nor the paper materials have found any information about the design drawings of the two underground facilities mentioned.

Even the corners of the underground shelter have been searched, but there is no information about it.

It seems to give the impression that the underground shelter and underground factory were secretly built before the disaster in the Blue Star World, otherwise it would not be possible to explain that the underground shelter and underground factory have such abundant material storage and a large amount of energy and mineral storage in addition to water resources.

But now is not the time to pursue those truths.

Xu Ran put forward this conjecture, and asked An An to help him record it, and when there are more resources that can be used in the future, he will investigate some neglected things in detail.

After inspecting the progress of the clean-up work of the underground power plant, Xu Ran is quite satisfied with the current work efficiency of the robot.

Because at present, after a carpet search in the entire fragmented city, a total of two hundred advanced robots manufactured by more advanced industrial technology have been found, and the more advanced robot industrial production, processing and manufacturing technology and industrial equipment production lines are completely absent in this fragmented city, but they are out of print.

Therefore, those 200 high-end goods are considered a baby bump for Xu Ran, and if you lose one, you will have one less, and it will be a big trouble to maintain and repair it if it is seriously damaged.

Therefore, the current work efficiency is already quite high compared with manpower, and Xu Ran does not dare to ask too much for the time being.

It is estimated that by the next time Xu Ran returns to the Fragment City at the large teleportation point on the side of the Earth Hatching Plant, the underground power plant should have almost been completely cleaned up.

During this time period, the fragmented city will probably experience two or three purple light scans, and it is convenient to further analyze and study the characteristics of the violet light by setting up a violet light sensor that has only recorded four times, and then making several important sensing records.

At the same time, if the large-scale teleportation point on the Earth's side is successfully set up, the energy storage center of the Space Key will also enter the testing stage.

After the space key can greatly replenish energy, Xu Ran will no longer be so picky and calculate the number of teleportations in and out of the fragmented city to save energy.

At that time, Xu Ran can go in and out at any time, as easily as his own back garden.

Therefore, the hard days are coming to an end.

This time when he entered the Fragment City, Xu Ran had no intention of bringing them back except for the instruments and equipment that had been dismantled from the warehouse and laboratory and brought them into the Fragment City along with the robots.

Because a large teleportation point is to be erected on the other side of the earth, the functional requirements of those instruments and equipment will be magnified several times, and those equipment will only set up a small and medium-sized teleportation point after the update, and this type of demand will not be needed for the time being, and the small Xu Ran will set up it in the basement of the new villa's home.

Xu Ran now has a successful experience in the erection of a teleportation point, and the erection of large teleportation points and directional transmission problems have also been easily solved, so that after the robot An An generates a tighter and more rigorous logical step, the robot will be more faithful and effective to help Xu Ran erect, the construction operation will be more refined, and the data will not have too much error, and it will be more accurate.

So these days, Xu Ran seems to be doing this and that outside, but in the middle of the night, in one of the two facilities of the remote and calm and unmanned egg garden, the robots are in full swing to set up a large teleportation point.

This time, when Xu Ran left the fragmented city again, he just continued to bring some auto parts, and after returning to the earth, it was still the middle of the morning, and after eating something casually, he fell asleep directly.

……

Early the next morning.

Every time Xu Ran came back from the fragmented space, he went directly to sleep, and naturally felt that his physical and mental state was very good after waking up.

Although this time was no exception, Xu Ran still vaguely felt a little cold, and he was woken up by freezing.

Because I don't plan to live in the warehouse anymore, there is no heating, and Xu Ran's physical fitness is relatively strong these days, and there is the attribute bonus of the fragmented city where the temperature is around zero degrees, but it is more cold-resistant, but it can be tolerated.

It's a bit cold today, though.

Xu Ran felt that it would be colder if he was lazy in the quilt, so after getting up, he took a cold water and wiped his face, and then moved his body, but he felt much better.

Changing into loose sportswear and shoes, when Xu Ran pushed the door open, a cold wind ran in, and even Xu Ran, who was in good physical condition, couldn't help but shiver.

There was a snowfall last night, and it wasn't that big.

Looking up at the concrete floor outside, the ground was wet, the snow had melted, and some of the tree pools and the roofs in the distance were covered with a layer of frozen snow chips.

Exhale a puff of atomized white air and take another breath of cold air, although it is cold, the air quality is very fresh.

After this cooling kills some latent viral agents, there will be relatively few influenzas, so there are many people who go out to exercise early in the morning.

"Xiao Ran, get up and run!"

"Xu Ran, it's morning!"

Today made Xu Ran a little surprised, when he came out to run, when he met some old neighbors on the road, those old people greeted each other kindly, and they got used to it every day, but those middle-aged elders and some young people rarely brought a smile to say hello.

Xu Ran thought that this must be for a reason.

This shouldn't be that Xu Ran suddenly became rich, they were like this, it is estimated that they heard something related to their own vital interests, so they suddenly became so enthusiastic.

When he was running, a self-proclaimed student had studied with Xu Ran in elementary school, but since then he dropped out of junior high school and started a small business, and now he only has a net worth of hundreds of thousands, but he has always looked down on Xu Ran's fat Liu Erping, so he cheekily came over and trotted side by side with him, and almost asked: "Xu Ran, I heard that we are going to be demolished here, is this true?"

Xu Ran said unexpectedly: "Where did you hear the news?"

Liu Erping looked around and said: "I just heard the news this morning, because there is an orphanage, the municipal planning has not considered demolition in this area, all because there is an old Yalin grandmother, every year in the province and occasionally there will be leaders to condole, and no one dares to force the demolition here, but now the news suddenly came out, it was the old Yalin grandmother who agreed?"

Didi!

Xu Ran hadn't spoken yet, he quickened the pace and speed of running, and suddenly two car horns sounded from behind.

Continuing to trot, Xu Ran turned his head and saw Susan trailing behind their butts in her Beetle.
