It's an earthquake! Almost without thinking, Chen Xin had already judged what was going on.

However, the intensity of the earthquake was not high, and it did not last long, and it only shook briefly before it stopped.

However, even so, Chen Xin did not dare to slack off, and hurriedly pushed the two air conditioners back to the inside of the shelter, and then checked the damage to the facilities in the shelter.

Although the shelter was built to the highest standards, and theoretically even a magnitude 6 earthquake would not collapse, Chen Xin could not tell how much the magnitude of the earthquake was just now.

And if you're not afraid of 10,000, you're afraid of what happens, and if something goes wrong, he doesn't pay attention, this is a really fatal thing.

Fortunately, after a round of inspection, the construction quality of this shelter is indeed passable, and there are no cracks or other damage, and even Chen Xin opened the system perspective and did not find anything that needed to be repaired.

"Woohoo, it seems that the construction team didn't brag at the beginning, and it can indeed resist a six-magnitude earthquake." While Chen Xin put some of the things that had been displaced or fallen back into place, he also praised the engineering team that helped him build the shelter in the first place.

It didn't take too long for Chen Xin to pack up his things, and after putting everything back in order, Chen Xin didn't have the mood and physical strength to toss the two air conditioners that had just been recovered.

However, when stacking these two air conditioners in the original garage, Chen Xin took a look at the workshop he had converted into a garage and suddenly found that this place was a bit small.

This is just a place designed by Chen Xin to park, although the car has been moved now, but the vacant place is about a car and a half.

It is more than enough to put a workbench, but it is a little crowded to put something else, especially when Chen Xingang dragged two air conditioners back, which suddenly made this place look cramped.

Looking at this cramped place, Chen Xin didn't have the idea of upgrading the workshop, but planned to upgrade the storage room.

Even if the workshop is upgraded, it is also upgraded in the direction of improving manufacturing and processing capacity, although the space and area will be improved, the degree of improvement will not be too high.

But now what Chen Xin needs is a place where he can put things, and from this point of view, it is much more appropriate to upgrade the storage room.

Especially these two air conditioners can only be regarded as hors d'oeuvres, but he also asked the SWAT team for supplies.

Thinking of this, Chen Xin naturally came to the door of his storeroom.

Chen Xin's storage room is actually not large, and only 10 square meters of space was left when it was designed.

There were six simple iron shelves against the wall in the room, which were filled with all kinds of food that Chen Xin had initially stored, as well as supplies that had been exchanged for the SWAT team and Mo Qingyan in the past few months.

In addition to these, the most occupied place is the freezer he got back from Mo Qingyan's house, which contains the vegetables harvested this month and the fish that have not been eaten.

Originally, it was only used as a food pantry, so it didn't need much space, just enough to put all the food in.

But after Chen Xin obtained the system, the function of the storage room was not only limited to storing food, but also a considerable part of the materials he exchanged from the SWAT team through Qin Lan were piled on the floor of the storage room, leaving him with nowhere to go.

And this is the result of piling all the cement in the corners of the public space outside.

"It seems that we have to make a classification, one for food and one for supplies." Looking at the stuffed storage room in front of him, Chen Xin scratched his head.

Although he is not the kind of hamster cancer who is reluctant to throw away anything and likes to hoard a lot of things, he still has a sense of pride and peace of mind when he looks at the stuffed storage room.

It's just that stuffing it like this is not the best way to store supplies, Chen Xin still plans to store food and other materials separately, and at the same time classify the materials.

However, the premise of this is to expand the storage room a little more, and divide at least two spaces.

"Cramped pantry"

"Upgrade plan 1: expand storage space, increase wall-mounted storage shelves, extend the shelf life of food storage, and upgrade the survival point required 800"

"Upgrade plan 2: expand the storage space, separate the material storage room, reduce the probability of material storage aging, and upgrade the required survival point by 1000"

The upgrade consumption is not large, and Chen Xin took a look, the two upgrade plans can expand the area of the current storage room by 50%, but the first plan is still a storage room, but the shelves are added to the wall, and some things can be put on the wall, which increases the space utilization.

As for the second plan, the storage room of the original one room was divided into two rooms, one large and one small, with the smaller one inside as a food storage room, and the larger one outside as a material storage room.

At a glance, he saw that the two plans were not bad, and the materials consumed were not much, so Chen Xin did not hesitate more, and directly chose the two plans to upgrade at the same time.

With the consumption of supplies and the flash of green light, the storage room in front of him did not seem to have changed, but there was an extra door on the innermost wall, and there were several more rows of shelves made of long boards on the wall, and the iron frame that was originally placed against the wall was also moved to the middle of the storage room, neatly arranged, and two new shelves were also added.

And this is not the most changed place in the storage room, the food and freezers that were originally placed here have disappeared, replaced by cement and other materials that were originally placed in the public space outside, all stacked here neatly stacked here, and materials such as steel bars that were previously stacked on the floor are stacked on the shelves in separate yards.

"Does the upgrade still come with a deposing warehouse? It really saved me a lot of trouble. Looking at the sorted materials, Chen Xin nodded with satisfaction.

This really saved him a lot of effort, after all, if he was the only one who had to tidy up the warehouse, it would definitely be a big project, not to mention anything else, it would not be an easy job to move a dozen bags of cement and that pile of steel bars.

Walking through the shelves to the innermost part of the storage room, the newly added door was opened, revealing a newly expanded space in front of Chen Xin.

The area is only about half of the material storage room outside, and the freezer and food that Chen Xin originally kept outside have been transferred here.

Stretching out his hand to feel it slightly, the temperature of this food storage room is a little lower than the temperature of the material storage room outside, but the low temperature is also more conducive to the storage of food, Chen Xin is very satisfied with this.

After checking and seeing that all the food was sorted on the shelves, he closed the door with satisfaction and exited the pantry.
