Xu Ran was disappointed.

He thought that through the surveillance video on the memory card brought back from the fragmented city, he could find out what kind of disaster had happened to the world that was exactly the same as the earth, and caused it to collapse into a fragmented space.

However, from the beginning to the end of that video, there were no other anomalous discoveries except for some transparent shadows and mysterious fluctuations in the last five minutes.

In other words, it is likely that the power was cut off in advance, or the equipment was damaged, so that the monitoring did not record the scene content at the time of the disaster.

The only clues left in the video are the mysterious fluctuations and transparent shadows that appear in the last five seconds of the frame.

Xu Ran watched that paragraph many times, and even took screenshots to enlarge the study, but he still couldn't figure out what the transparent shadow was and what the mysterious fluctuations were.

But Xu Ran was not in a hurry.

Although he didn't know how much time had passed in that fragmented space, there were always some important clues left in the intact city for him to explore and investigate.

……

The night was long, and the wind was still there.

At this time in the past, after Xu Ran sorted out the old goods in the warehouse, he would stay in front of the computer in the office to update the information of the goods in the online store to see if anyone had placed an order.

Once someone places an order to pay, he will take out the goods and send them to the collection station set up by the courier company not far from here overnight, so as to deliver the goods to the buyer as soon as possible.

However, now, all of Xu Ran's mind has long been firmly attracted by the fragmented city in the alien space hidden in the mysterious metal object.

After researching and examining the items brought back from the Fragmented City, he knew that the city in the fragmented space where the mysterious metal object was hidden and survived the catastrophe was a huge treasure that could bring him infinite wealth.

After two experiments, Xu Ran also had a general understanding of the energy replenishment and consumption of mysterious metal objects.

In order to replenish the energy of the mysterious metal block, Xu Ran spent half a year through a number of experiments, and in the process, there were many failed experimental attempts, and finally succeeded by introducing drought thunder and lightning.

It's just that thunder and lightning weather doesn't occur frequently, so this method of energy storage can only be regarded as a stupid method, and it needs to be further studied and improved.

In terms of energy consumption, Xu Ran explored and brought back some small objects with a total weight of only ten catties, and together with his own entry and exit, he consumed about one-fifth of the energy, indicating that the consumption was still relatively large.

Not only that, in the process of one in and one out, Xu Ran found that he lost more water in his body, and he didn't know what caused it.

On this issue, Xu Ran planned to enter the fragmented city again to do an experiment.

This time, Xu Ran will make some preparations.

He picked out a few small old goods weighing no more than five catties in the warehouse, brought a three-liter bottle of mineral water, a mechanical watch, and some snacks to eat, and put them all into the bag he brought back from the fragmented world.

Subsequently, Xu Ran chose an open space in the warehouse, adjusted the newly brought back and extremely powerful future mobile phone to the video mode to face that position, and then used another mobile phone to set the timing function, and then entered the mysterious space again.

This time, it went very smoothly.

The world in front of him was still the familiar one with a leaden gray tone, and it was not the same as what Xu Ran had seen and felt the last time he entered.

However, the location where Xu Ran came in changed, not the village and town, but was directly sent to an empty open space near the city.

There was an irregular large stone near the clearing, the protrusion was only five centimeters above the ground, and Xu Ran vaguely felt that the big stone seemed to contain a kind of energy.

I remember when I first came in, near the village, there seemed to be a smaller stone than here, but I didn't notice it at the time.

Xu Ran guessed that there was a change in the location where he was teleported in, which might be subtly related to the stone, so he took a sample and planned to take it back to study.

However, the main targets of this time coming in were not these, Xu Ran checked the bag he brought in as soon as possible.

Surprisingly, except for the bottle of water, which was about one-third less than the bottle of water, the rest of the contents were the same, and there was no qualitative change.

In this fragmented city, there are no traces of hardened roads outside, except for the dry gray earth, and only those well-preserved buildings remain.

But in that surveillance video, he saw exactly the same scene as on Earth, with roads leading in all directions, pedestrians rushing by, and vehicles staggering.

Now, however, there is nothing outdoors but the flat, grey earth and well-preserved buildings.

It can also be said that anything related to survival, such as food, water, microorganisms, etc., does not exist here.

This phenomenon made Xu Ran puzzled.

Xu Ran picked one of the most conspicuous iconic buildings in this fragmented city, which was once the city's former commercial center.

He went to the top floor where he could overlook the entire city to get a bird's-eye view, but he found something anomalous, that is, most of the urban buildings in this fragmented space seemed to be in a slightly inclined state.

But Xu Ran himself stayed in the building, but he couldn't feel it at all.

There is also nothing outdoors, but in those buildings and houses, everything is still in its original state, and many scientific and technological crystallization and civilization clues can be found in it that can feed back the legacy of this world, which is indeed exactly the same as the earth, but the timeline is 20 years ahead.

Of course, Xu Ran didn't come in this time to find the truth about the broken world, as well as some secrets contained here that need to be confirmed through testing and experiments.

With his current conditions, it is impossible to build a large-scale laboratory and all kinds of experimental instruments to decipher and find the hidden truth behind this fragmented world, even if all kinds of very professional experimental equipment and testing tools he can't afford to buy.

As we all know, engaging in scientific research is very expensive to do.

To delve into the mysteries of this mysterious space, Xu Ran must have a strong scientific research team and invest a large amount of money.

Therefore, Xu Ran's primary purpose in entering the fragmented city this time was to use the resources of the fragmented city in this space to create wealth for himself.

Placing the old warehouse goods brought in on a table, Xu Ran picked up the electronic timer and found that the time on it was still flickering at the point in time before he entered the space, and it was not timed normally.

After adjusting the time of the timer to 19 o'clock in Earth time, the timer began to beat normally, and nothing abnormal happened.

Xu Ran found a drawing board, stood on the highest floor of this fragmented city, and took this building as the center and used it as a reference object to outline the outline of this fragmented city.

Once you have a rough outline of the city, you can draw a rough and simple map by planning the roads according to the gaps between the buildings, and then identifying the buildings of some special functional institutions, and adding some eye-catching and recognizable buildings in the vicinity.

Because in the future, he will search this fragmented city, and every time he searches, he will mark it on the map, so that he can save some time-wasting repeated searches.

As the saying goes, sharpening knives does not mistake woodcutters, and it is still necessary to make some plans in advance.

After drawing a simple map, Xu Ran began to search from the top floor of the commercial building, classifying and counting the well-preserved materials.

However, the search for such a 19-story building takes a lot of time and effort.

After resting for a while, eating something and drinking some water, Xu Ran shared about seven hours before he basically took stock of the well-preserved materials in the building.

But in some of the floors, like locked safes, and metal doors that can't be opened for the time being, he only made a rough count.

In summary, there are tens of thousands of well-preserved items and thousands of valuables in this building, and there are dozens of vehicles of various types in the underground garage.

Especially among those vehicles, there are some luxury cars, although they look covetous, but there is no fuel, no electricity, no use, no Xu Ran can drive away.

However, there are certain factors that limit the need to bring items back to Earth, and Xu Ran needs to figure out the secret, and his attention does not stop at those vehicles.

After the entire building was basically searched, Xu Ran did not search elsewhere.

Being in this space for seven or eight hours made him feel a little tired.

He picked out a few valuable diamond rings and gold jewelry, and put a few experimental items he brought in from the earth into his bag, estimated to weigh a total of ten catties, Xu Ran took out the mysterious metal block, opened the space door and returned to the earth.
