It's been more than two weeks, and the food in Zhang Xu's quantum instrument is actually enough for him to eat for another 3 weeks, but there is not much water, only enough to last a few days, which is very troublesome.

After learning on the radio, this virus is infected by human DNA, 91.6% chance of being infected into a human-eating zombie, although it is not 100% but basically no one will die, other animals and plants only have a 5.73% chance of infection, but experts said that after diluting the virus by nature, there is only a small chance of infection when exposed to the virus, and there is a great chance of infection when taking it, so the water source problem is Zhang Xu's biggest problem.

There was no way, without the help of water, the source of life, Zhang Xu had to find a way to search for mineral water to save himself.

The power went out just a week ago, but Zhang Xu's quantum meter can be said to have a quantum power plant.

There is microwave heating with a quantum meter, and the canned food is taken out of the wax and chewed to eat, and these cans are all eaten these days.

There was a sound of squeezing, Zhang Xu knelt on the sofa and kept banging on the window.

"Hey, anyone?" Zhang Xu has been repeating such things these days, and Zhang Xu, who felt a chill, hugged his arms tightly, and the cold air made him unprecedentedly sober.

Why did the amiable neighbors who used to greet each other through the window, but now why are they all huddled in their homes and tighten the curtains, is it because there are more terrifying zombies?

Although there are indeed survivors in the building, they don't dare to open the windows, more is better than less, they would rather starve to death than open the curtains to communicate, Zhang Xu originally wanted to exchange the food in his hand for water, but there was no way, he had to go out to find a water source!

"Remember this last days, put away your kindness, Zhang Xu! Your life and death are not as important as a bag of bread, hehehe......" Zhang Xu looked up at the ceiling for a long time, his empty eyes seemed to have lost their former brilliance, and he smirked alone.

But Zhang Xu has always been an ordinary high school student, kindness is still engraved in his mind, which is difficult to erase, but over time, Zhang Xu's fantasy people will be like cold water, pouring on the top of his head, slowly eroding his cognition!

……

After devouring his food, he began to work, pulled out a hammer, a vice, and a saw from the toolbox, put the kitchen fruit knife in his trouser pocket, and vacated the books in his bag.

"Huh?" Zhang Xu saw some protective gear from the corner, which was Zhang Xu's bicycle helmet at that time, handguards and wrist guards, etc., of course, they were all worn by Zhang Xu when he first learned to ride a bicycle.

In addition to the helmet that you can't wear, you can barely put it on.

Zhang Xu also thought about it, and tried not to expose the ultimate quantum instrument in front of others in the future, put on his schoolbag, bring a flashlight, mobile phone charging treasure and the like, and go to the platform on the top floor first.

Entering the corridor, there was only a trace of brightness from the roof of the building in the dark corridor, the electricity had been stopped, and he turned on the flashlight carefully, only to hear the low roar of the zombies downstairs, almost in the corridor between the 5th and 6th floors, Zhang Xu stood on tiptoe carefully, and he didn't dare to close the door, for fear that this small closing sound could attract zombies.

Zhang Xu immediately jumped onto the top floor platform, gently pushed open the small door on the top floor, creaked, and a harsh sound came out, Zhang Xu immediately lay on the staircase and looked at the figures of the zombies below, fortunately they did not move, it was really a false alarm, for fear of being heard by the low zombies, wiped the cold sweat on his forehead, Zhang Xu finally went to the roof.

As before, there was still some snow and a utility room, and there was nothing to use if I turned it over, but there was an iron door frame that caught Zhang Xu's attention.

Zhang Xu knew that there were a few zombies blocking the entrance of his own aisle, so he could only look at the situation on the opposite floor, the distance between the opposite building and Zhang Xu's building was almost more than 3 meters, and if the door frame was placed on the upper floor, one could climb over.

If the opposite corridor doesn't work, you can go back, just do it.

Zhang Xu found a few rusty vices in the pile of debris on the top floor and turned them around the door frame several times, fixed them on an abandoned table, and fixed them to see if they could bear his weight when they stepped on it, after all, this is the twelfth floor, if it is not safe, it is better not to do such a risky thing.

In fact, others ask more than 3 meters and a sprint jumps to the opposite side, why bother? But think about it, it's the top floor after the snow, there is snow on the surface and it's slippery, it is estimated that he slipped before he jumped, and Zhang Xu This is a standard fat house, can he jump over a distance of 3 meters?

It took half an hour for Zhang Xu to barely reach the opposite building, but the building gave Zhang Xu a surprise, the people on the top floor actually planted vegetables in the utility room, and it was the kind of tomatoes and cucumbers that were eaten directly, covering half of the room with plastic film, which was very warm.

In the 23rd century, due to the large population and the complete lack of housing area, there are these large-scale soilless cultivation bases, which do not require too many farmers to work, so most people do not know how to grow vegetables now, Zhang Xu did not expect to be able to eat vegetables grown on the soil.

Zhang Xu salivated when he saw these vegetables, immediately picked a tomato, rubbed it on his clothes, picked it up and ate it, he hadn't eaten vegetables for a long time, he ate it happily, the sweet and sour tomato juice flowed into his mouth, he ate one in less than half a minute, and picked a cucumber, and he wiped it on his clothes and gnawed it directly, click, click, click.

After eating, it's time to go to the corridor opposite the building to check, and by the way, these fresh vegetables are received in the quantum meter, after all, there are few zombies in the entrance of the corridor opposite Zhang Xu, and it is best if there are no zombies.

Gently push the door open, there are no zombies, so Zhang Xu quietly walked down, because there is an elevator, so the corridor of the safety exit is basically no one will go, each safety exit is open, the emergency power supply inside flashes a green shimmer to prevent fire, and one meter outside the safety exit is the resident's residence, the door is built opposite, and then next to the elevator is the door, due to the power outage, the elevator has long been closed.

When he walked to the 8th floor, Zhang Xu saw that one of the doors was covered with bloodstains, the blood had dried up, and there was actually a piece of minced meat on the ground, which was more terrible than a horror movie, Zhang Xu smelled the smell of blood, the cool air rose from his toes to his back, and his back was wet, the door was already half-open, and there was a low roar of zombies inside, which was more than a meter away.

Zhang Xu held his breath and immediately retreated, not daring to come out, for fear that the zombie's sense of smell would smell human flesh.

On the top floor, Zhang Xu was like an ant on a hot pot, crawling back from the opposite floor, if he really couldn't think of any way, he had to kill the zombies on the 8th floor, so Zhang Xu went home first, after all, there were too few things to use, so he could only break open the homes of other citizens to find things to use.

In order to prevent zombies from rushing up, Zhang Xu blocked chairs, sofas, and tables on the corridor of the 10th floor safety exit, so that Zhang Xu could search for the 11th and 12th floors with peace of mind, so that even if the door was broken, the zombies would not necessarily rush up, although the strength after infection was 1.5 times that of adults, but ordinary wooden tables and sofas could not be destroyed.

Zhang Xu simply blocked the wardrobe and refrigerator in the corridor, and after doing this, Zhang Xu sat on the floor, gasping for breath, and began to pick the lock after resting, after all, the security door of the community is really difficult to pry, only the lock hole, don't want to see any screws.

This is difficult for Zhang Xu, after all, he is just an excellent high school student, who knows how to pick the lock?

If you smash it with a hammer, it is estimated that the door will not be opened, and the zombies will block it first.

Watching TV, it's all wires that can be opened with a single touch, and Zhang Xu hasn't tried it, so it's so easy?

There is a mini lens on the Bluetooth headset that can be observed, and Zhang Xu immediately asked: "Xiao An, analyze it, is there any way to break this anti-theft door?" "Zhang Xu's wisdom is limited after all, and he has to brainstorm to have a better way.

"According to data analysis, there is a liquid nitrogen making machine in space 6, and the owner can use liquid nitrogen to break through the security door." Xiao An deserves to be a highly intelligent system, and immediately came up with a solution. (Liquid nitrogen means that nitrogen is in a liquid state, and as for why the air becomes liquid, it is because the temperature is low to a certain degree, and nitrogen will turn into liquid.) Therefore, the temperature of liquid nitrogen is extremely low, and when it hits iron, the iron will become extremely brittle and shatter when it is knocked. ）

"Liquid nitrogen, that's good." Zhang Xu got almost 500 ml of liquid nitrogen in less than half an hour, in fact, the instruments in space 6 were equipped with liquid nitrogen making machines in order to cool down, which were used as refrigeration units for quantum power stations.

Zhang Xu put on special gloves and poured the lock cylinder again, and it didn't take long for Zhang Xu to smash the glass-like lock with a hammer, and the door naturally opened.

As soon as you enter the door, you will have the feeling of the new year, what the word "spring" and the word "Fu" come into view, and all kinds of window flowers are all over the living room.

Due to the outbreak of the virus, when he went home for the New Year, he went to his relatives' house to visit the house, and this neighbor was estimated to be no exception, Zhang Xu happily found a lot of food, counted it, there were 3 boxes of eight-treasure porridge, 2 boxes of yogurt, 3 boxes of Wang Lao, 6 boxes of biscuits, 2 baskets of fruits, 3 boxes of vacuum-packed beef, 5 large bags of spiced peanuts and 5 large bags of creamy melon seeds, these were found on the living room table, anyway, there were 50 cubic meters in the No. 7 space, and the water in it was running out for a long time, which was a timely rain for Zhang Xu.

30 catties of air-dried bacon and a few sausages entered Zhang Xu's eyes and entered the kitchen, Zhang Xu also saw two huge carp, which had been sprinkled with salt and were being air-dried, in line with the principle of not wasting, he also found many bags of quick-frozen dumplings and mutton from the refrigerator, of course, there were dozens of white steamed buns, anyway, the time flow rate of the No. 7 space was forbidden, and these things would not be bad if they left the refrigerator, and finally found a few packets of dried fungus, dried Xianggu and other vegetables, as for the fresh vegetables Zhang Xu did not see, and there was a large pot of rapeseed oil, By the way, there was also a bottle of vinegar and a few bags of salt.

Just when Zhang Xu was immersed in joy, he didn't know that there was a dark shadow on the living room door, and slowly leaned over.
