For the next nearly a week, everyone was recuperating, nothing strange happened, and the team got along relatively well.

It was also during this time that Xu Yang's arms were also relieved, because many plants had begun to sprout in spring, such as some plantain and dandelions, etc., which gradually grew, including the area within the besieged city, which was considered to be long and lush, so that when Liu Yue occasionally went to the wellhead to draw water, he could also pick a little, which was not only for Yan Xueli to heal his injuries, but also for Xu Yang.

These can be applied externally and internally, all of which are good medicines for anti-inflammatory and stasis, plus Xu Yang has recently reduced the big movement of his left arm as much as possible, and with proper maintenance, the wound on his arm has finally eased up after a week.

Of course, in addition to the injury to the arm, there are many things to do, for example, with the amount of two meals a day, a jar will soon bottom out, and other canned meat, etc., have also begun to gradually decrease, in other words, it is time to forage for supplementary food, which is also a problem that will be faced forever under the desert island.

Fortunately, it is not without direction now, at least the seeds have been left, there is a field that has been reclaimed at the back of the house, which is also the boundary that the former owner Cheng Bing has reclaimed first, you only need to pick up and pick up, shovel off the previous pole with a folding shovel, loosen the soil, and then sprinkle the seeds, and then match some fertilizer in the later stage, Liu Yue is familiar with this matter, her long arms and legs, at first glance, is a daughter-in-law who can work in the countryside, basically Xu Yang explained to her, and the two of them can cooperate with each other.

Of course, the existing fields are still relatively scarce, and the amount of planting is enough for one person but not enough for four people to survive a few months, so Xu Yang also opened up the land boundary on the original basis, planting corn on one side and potatoes on the other.

In the case of potatoes, the seedlings are also left early, that is, they are placed somewhere, sprinkled with water, and let them sprout, and then cut into pieces according to the structure of the long buds, and then put them into the soil and plant them, and the process is basically the same.

However, there are some more difficult things to talk about here, in terms of the nutrition of the land, it may have grown two or three waves, so this is still quite wasteful, so the future growth is afraid that it will be affected, so Xu Yang also needs a lot of fertilizer to improve the soil quality.

The raw materials of fertilizer are feces, urine, etc., which requires Xu Yang to talk about it, to keep the girls' convenient night pots, Liu Yue is still relatively familiar with this matter, but the other two girls blushed when they heard it, thanks to Liu Yue's help to explain it, they passed the psychological level.

Of course, there is a relatively large amount of fertilizer, and the people are not enough, so in a short period of time, some wild deer and horse dung outside, Xu Yang also collected and collected them when he saw them, and put them into a pottery jar made in a unified manner, and then added some fallen leaves to stir them, wrapped them in a tent cloth and sealed them with ropes, and placed them in an area far away from people, so that they could ferment and ferment after nearly a week before they could be used and began to sprinkle these made fertilizers on the cultivated fields.

This is a long-term plan, to wait for maturity and harvesting, at least another two or three months, but during this period, Xu Yang has to quickly prepare a cellar granary for the second half of the year, so that during this time, Xu Yang said that he was idle, but in fact he was not idle, and in order to survive, he had to do a lot of things every day.

Liu Yue is a good girl, when it comes to farm work and the like, she can immediately draw inferences, so the miasma forest not far away has a lot of rotten wood because of the lack of sunshine all year round, but not all of them are highly poisonous, some rotten wood is brought back, and there is black fungus growing on it, this thing is known as the king of vegetarian food, not only is it not toxic, but also has excellent nutrition, Liu Yue proposed to build a mushroom shed in the next room, which is used to make mushrooms and fungus, so as to enrich the cuisine of the daily diet.

Just within this week, the rotting wood has begun to grow, and it will take about twenty to twenty-seven days before the ears will appear, which can temporarily relieve a little of the embarrassment of insufficient food and rapid consumption.

Of course, far water can't solve the near fire, and in the middle of this interval, they can't just eat soil, they have to find a way to hunt, catch some fish or find a way to solve the food problem, otherwise no matter how much food planting plans there are, they can't help the current way of not having enough to eat.

As a result, Xu Yang began to lay some simple pit traps, animal traps, bird traps, etc. in the nearby forests, trying to get some meat to eat, and also developed the edge of the territory around, trying to find something that could satisfy hunger, but in late winter and early spring, there are still not many things to eat, and traps are not very useful here.

The foxes here are more tricky than those in other places, and they will destroy the traps, or deliberately sprinkle fox urine around, etc., so that hares or roe deer rats will run away when they hear it, and over time Xu Yang also understands that the fox boss does not want Xu Yang to rob them of food in this forest.

Helplessly, this can't do that either, wanting to eat meat has almost become a hot topic in the camp in the past two days...

Qin Xiaoyun didn't care very much, she used to be a dieter, and now this situation is nothing to her, so her main thing every day is to study the report, and plan to try her best to crack the mystery, wanting everyone to return to the era of being able to use electricity.

Not to mention, it's really a bit of a sprout, but it's really different from what Xu Yang thought...

Just a week later, Xu Yang, who was drinking tea and taking a break in the house after doing farm work, chatted with Qin Xiaoyun, who was sitting over, about this topic.

"So, instead of cracking the secret of the geomagnetic field and then allowing electricity to operate, it is the opposite, using the existing geomagnetic field to convert some kind of magnetic energy into mechanical energy, and then let the mechanical energy into electrical energy, and then let the electricity be used, right?" Xu Yang asked.

Qin Xiaoyun nodded, took a sip of tender bud tea, and then said: "That's right, that's what it means, it's like a dam generating electricity, converting the potential energy of water into electrical energy, but here you can rely on some kind of magnetic energy instead of potential energy, I think it can be tried." Before use, it is still necessary to have the equipment needed for power facilities, generators, power storage facilities, wires and electrical appliances, which are also indispensable, as for the use of magnetic energy, a special mineral is needed, I will write out the list of needs one by one, as long as these are prepared, I think we can enter the era of electric energy. Brother Xu? Do you think this project is feasible? ”

"You can try, anyway, we also have ready-made materials, such as generators, batteries, these are available, there is a certain foundation, as for wires and the like, I remember that there are a lot of them in the base, you can go and pick them up, and if you have electrical appliances, there are abandoned factories..."Xu Yang said.

"Can you try? Xu Yang, you forgot, we are in a famine now, how can we have time to do this... Mr. Qin, I think this can be put aside first, and we have to find a way to solve the problem of food and clothing first. Liu Yue said hurriedly.

"Well, I'm quite Xiaoyue about this, especially Brother Xu, you are doing the most work now, if you don't have enough to eat and do other things, there will definitely be problems. Sister Xiaoyun, don't think about it, I'm not against you, I just think I should mention it..."Yan Xueli also said.

Since the last incident, Yan Xueli has obviously listened a lot.

Xu Yang immediately said: "What you said is quite right, but you also misunderstood what Xiaoyun meant, you should all want to leave this island alive as soon as possible, right?" If you want to, then you have to use the electricity as soon as possible, because with electricity, we can make the on-board equipment start, a steady stream of electricity, can allow us to try to generate waves to the outside world countless times, maybe it doesn't work once, 10,000 times it will be? This is the way to solve the root cause. ”

Qin Xiaoyun nodded, and couldn't help but look at Xu Yang with some appreciation, who understood her thoughts, speaking of so many people, that is, he was alone.

The two girls also understood why Xu Yang and his family had to do this recently.

Instead of aimlessly seeing the moves, it is better to think of a way, directly move the general, and then solve the problem perfectly.

"However, the famine is also true now, I try to think of a compromise to solve the problem, right? Don't worry, everyone. Xu Yang comforted.

The girls looked at each other, but could only sigh...

But at this moment, there was a sudden noise outside the house, a cold intonation voice...

"Don't just draw cakes, do you think two words will solve the problem? To solve the food famine, you have to come up with practical solutions..."
