Time passed in a hurry, and half a month passed in a blink of an eye.

Located in a river valley in the Daqingshan Mountains, the vast cedar forest is lush and green, and the tall and straight tree trunks stand on the steep slopes, which at first glance look like guards guarding the mountains and forests, holding the sky high above their heads.

Like an isolated secret realm, when the whole world is being disturbed by zombies, there is a trace of comfort that is difficult to maintain.

On a path between the cedar trees, a group of people is moving slowly, a total of four people, two men and two women, walking and looking around from time to time, as if they are carrying out patrol tasks.

"Hey, this day has passed, and a bird is about to fade out of his mouth!"

There was a yawn, and one of the men, in his mid-forties, grumbled gloomily. He carried a flat pole on his shoulder, carrying two red plastic buckets in front and back, and as he walked, the flat pole flicked one by one, and a few splashes of water stirred up from time to time in the red buckets in front and back.

Hearing his complaints, the two women who walked in front looked back at him, ignored them, and continued to patrol the surroundings one to the left and the other to the right.

Seeing that his words were ignored, the man clicked his mouth, turned back to Su Junwu, who was following him, and said: "I said Xiao Wu, we haven't eaten meat for almost half a month, we eat bamboo shoots, wild vegetables, and canned packaging every day, this life is sad enough!" When will I be able to eat meat once? ”

Seeing this, Su Junwu had to smile helplessly: "Uncle Wen, there is no way to do this, we are staying in the forest farm now, and we are short of any materials, so we can only endure it." In addition, eggplants, potatoes and other farm crops will be ripe in the next few days, and the food will improve by then. ”

"That's true, but there's still no meat!" Hou Xunwen sighed regretfully, this is all fate, who said that he encountered the zombie apocalypse when his life was getting better and better. Speaking of which, I am quite lucky, thinking that others have become terrifying and ugly zombies at the beginning of the fight, and I am at least alive now.

Speaking of canned food, there are a lot of other packaged foods, but these are shelf-stable materials, and they are not willing to use them easily.

The big guy also opens a canned food every few days to taste meat, which is the biggest limit.

Especially in the past few days, with the various consumption of the past few days, it is a time when the green and yellow are not harvested, as Hou Xunwen said, a bird is about to fade out of his mouth!

"Hey, I said Ziyan girl, what was the feeling of those who turned into zombies at the time, if there was no pain, I think it might be more liberating to become zombies, saving us from being like us, not only not eating and dressing well, but also worrying every day."

Glancing at Su Ziyan who was walking in front, Hou Xunwen shouted jokingly.

After getting along for the past few days, Hou Xunwen found that Su Ziyan's nature is actually very gentle, she is a very easy person to get along with, not at all as fierce as she seemed that day, the beam that formed with her at the beginning slowly faded away, and she often screamed like this, "Ziyan girl, Ziyan girl", as if she had become her elder in a trance, and she looked like she was "relying on the old and selling the old".

Zhang Xiaojing turned her head, frowned lightly and said: "You are content, it is better to die than to live, no matter how bad it is, at least you are still alive, and Ziyan has not changed into a zombie, how does she know how she felt at that time?" ”

"Haha, that's what I said!" Hou Xunwen was having fun, but he didn't care about Zhang Xiaojing's tone at all.

"If Uncle Wen wants to turn into a zombie, we can open an opening for you to go out, hula and roar, and keep those zombies on call!"

Su Ziyan glanced at Hou Xunwen, and recalled the night of the virus outbreak in her mind, when she felt really uncomfortable being infected, and then she transformed inexplicably...... She couldn't figure it out herself. Gently tap the icicle on the side of the road with your hand, and suddenly make a "dong dong" sound.

With a tearing sound, Su Ziyan touched her hand to an icicle that looked a little deformed, and as soon as her heart moved, a terrifying cold air came out, and the icicles that had melted and flowed immediately seemed to have been reinforced, and they became round and erect again, braving the cold.

"Water!" Su Ziyan's mouth opened slightly, and she spit out a word.

Su Junwu understood, and immediately scooped up a scoop of water from Hou Xunwen's bucket with the plastic spoon in his hand, and then skillfully splashed it at the row of icicles on the side. The liquid flew through the air, creating a long, spill-like strip.

Su Ziyan's heart moved slightly, and she controlled the flying liquids with her abilities, turning them into crystal ice crystals, flying and attaching to the middle of the icicles. Soon, the slender icicles were strengthened again, and between the icicles, a dense network of spider webs was formed......

"Tut, if you want to say that, we are fortunate to have Ziyan girl in the team, you look at this icicle, if this is replaced with wood and built up one by one, I don't know if I will get the Year of the Monkey and the Horse Moon!"

Hou Xunwen looked at the row of ice belts on the side of the road, and praised it.

As early as ten days ago, the reinforcement work of the forest farm activity area has been fully completed, and the focus of everyone's attention has shifted from personal safety to the cultivation of crops and the acquisition of various resources.

For the more than eighty survivors in the forest farm, once the safety factor is resolved, the source of food becomes the primary consideration, and naturally cannot be missed, and in the face of objective reality, people have to take the risk of going out to work. Fortunately, there is a relatively complete irrigation system around the farmland, which gives Su Ziyan room to play.

Icicles rise from the ground, which protects the safety of workers to a certain extent, so that everyone can work with peace of mind.

As for the forest area, considering the bare state of the back mountain, although it is blocked by lofty mountains and mountains, people are like this, it is easy to be suspicious, and psychologically it is still unsafe, so Su Ziyan painted a gourd in the same way, and built a row of solid ice belts in the entire forest area as a simple protective fortification.

"But it's made of ice, so it needs to be reinforced often!"

Su Ziyan sighed, she had to carry out this kind of work every two days, and she had to walk around the entire forest area at a time, the whole process was time-consuming and laborious, and it took more than two hours to go down in a circle, and people were tired and collapsed.

But because of this, Su Ziyan's ability is being trained almost every day, and compared with more than half a month ago, it has made great progress. At this time, if she were to perform the icicles that were cast on the Shizi River Beach that day, although she would still be tired, she would not be so tired that she would not even have the strength to stand.

Su Ziyan estimated in her heart that with her current ability, the scale of the two days should not be a problem.

"But it's also strange to say, why is it the same ice cube, the ice cube produced by Ziyan girl's ability seems to be a little stronger, and it melts very slowly?"

Bang knocked on the icicle with his hand, and Hou Xunwen looked surprised.

The real ice cubes are particularly brittle, and they may break and collapse after a few hits with an iron hammer, but the ice cubes produced by Su Ziyan's ability have been tested and found that they are unusually strong, and only the ice chips on the surface have been smashed off by a few hammers, as if it is very difficult to break.

And the melting speed is also very slow, in a 20-degree environment, it is not a problem to last for five or six days, take the row of icicles on the Shizi River Beach as an example, after Su Ziyan's observation, they were not knocked down by the group of zombies until the sixth day, which shows its persistence!

So for the sake of safety, Su Ziyan has to reinforce the ice belt on the mountain and in the field every two days.

Zhang Xiaojing nodded thoughtfully, reached out and stroked the cold ice, and said with her lips slightly open: "And the color is also a little different, if you look closely, these ice cubes still have a hint of light blue, which is really beautiful!" ”

Su Ziyan smiled and glanced at this quite capable female player, although she was not particularly beautiful, but she was not as fragile as ordinary women, and after a few days, Su Ziyan knew something about her and felt very satisfied.

"Ordinary ice looks white, because there are a lot of bubbles inside, and when these bubbles are completely removed, pure ice cubes are obtained." Because ice contains a large number of hydrogen bonds, about twice as many as in the state of liquid water, these hydrogen bonds have a weak absorption peak in the red region of the spectrum, and after absorbing some of the red light, they appear as blue or light blue. ”

"Sure enough, it's a cultural person, I don't understand this even hydrogen bonding thing!" Hou Xunwen said haha, looking at Su Ziyan with a beautiful face, with a look of admiration.

Su Ziyan shook her head slightly: "The water molecule is composed of one oxygen atom and two hydrogen atoms, and they are bonded by chemical bonds, which is a very strong bond. Hydrogen bonding is a kind of interaction between molecules, that is, the mutual attraction between hydrogen atoms in several adjacent water molecules and adjacent oxygen atoms, although it is not as good as the binding force inside the molecule, but the number of hydrogen bonds is more, the stronger the binding ability of each other. ”

"To put it simply, the more hydrogen bonds there are, the stronger the internal stability!"

The biggest difference between the ice cubes produced by Su Ziyan through the ability and the ice cubes naturally formed in nature is the arrangement of the molecules inside, and its special and meticulous arrangement causes a very large number of hydrogen bonds to exist inside, and these hydrogen bonds do not expand the ice cubes because of the selectivity in the direction, resulting in a decrease in space utilization and a decrease in density, but they are arranged together very carefully, and these hydrogen bonds are firmly combined, making the ice extremely hard.

At the same time, because the melting of ice requires the breaking of hydrogen bonds, which is a process of absorbing energy, in the case of a large number of hydrogen bonds, the energy provided by the outside world is insufficient, which delays the melting speed to a certain extent.

Of course, there is no need to go deeper, Su Ziyan is a pragmatist, and how to use it simply and efficiently is what she cares about. In addition, as the main body of the ability, when the ability is cast, she watches the movement of each water molecule like a mirror in her heart, although she is still a leopard in the tube, but she also deeply understands the changes that are taking place.
