With this number, Shu Han was overjoyed, originally he thought that he would not be able to get the answer until these people returned to normal, or these people also forgot this number after returning to normal, and then he would have to repeat the above steps again, but in the end, the effort paid off, and it was successful at one time, Shu Han asked these people to heal themselves, and then took this number and handed it to the research institute for them to debug.

Under the order of Shu Han, as early as a year ago, the sound experts of the Survival League gathered together and began to discuss the production of headphones, and how to maintain a constant audio in the headphones, which is actually not difficult, in modern times, with the birth of electricity, telephones and tape recorders and radios and other equipment were soon born, the transmission of sound is to put it bluntly is to transmit vibration, sound is a frequency of vibration, this is sound, as long as you understand this, you can quickly work out the transmission method, The reason is not difficult, but how to shrink the device is relatively difficult.

After all, these people need to act alone, everyone can't be set off by a generator and a huge expansion headset alone, this is a forest, even if it is walking on foot, it is enough to make people torture enough, not to mention carrying dozens of kilograms of equipment, as for approaching it from the sky, it is even more difficult, such heavy equipment will make the hot air balloon unable to reach the intended target, which is difficult.

So the equipment must be small, and this is a huge test for the processing system and parts system of the Survival Alliance, even if the research began a year ago, until now, there is no good solution, only to rely on hundreds of years ago parts for collage and modification, and then build these headphones, the number is not much, but more than fifty payments, this number is far from Shu Han's requirements.

After all, the monkey hallucination is just one of his kung fu, just with his mountain-like body, it is enough to make the survival alliance have a good meal, not to mention others, so even if the monkey's illusion is eliminated at that time, but if you want to defeat that monkey, at least a hundred or more Skywalkers are needed to participate in the battle, then you need at least a hundred headphones, and at the same time, you have to test the sound before, this hertz number is just an approximate range, and it needs to be accurately adjusted, which requires more headphones, so this is obviously not enough.

But at this time, these experts can't help it, production and processing is not only by brains, but also needs a comprehensive upgrade of the entire industrial system, and now the power of the survival alliance, at least it takes more than ten years to make the modern equivalent of the sixties and seventies of the kind of plug-in headphones, no way, even if there are drawings and design schemes, but only less than seven million people, the number of scientists who can support is really limited, and a large part of them must be engaged in research on national defense projects, Headphones are a thing that can't mobilize much resources at all, and more than ten years is also a conservative estimate, if you really look at it, it is absolutely impossible to make it without twenty years.

Shu Han has no way to do this, the improvement of science and technology is not achieved overnight, he can't put aside the national defense project and medical project for the sake of a headset, and specialize in a pair of headphones, if he really wants to do this, he will definitely be blocked by those Skywalkers, after all, this survival alliance is not a place for him to cover the sky with one hand, so Shu Han can only helplessly put it down.

But fortunately, the previous steps don't need too many headphones, for this reason, Shu Han can only inspire some soldiers to go on adventures, this is no way to do things, in the current situation of no robots, they can only obtain this information through people, Shu Han also made a very heavy commitment to them, every soldier who goes, whether dead or alive, will be taken care of by the state in all aspects, and their children will be arranged by the government to arrange their work, whether it is to work in the army or government departments, Everything is taken care of by the government, their parents will also receive special treatment from the government, and if they survive, then their future will be taken care of by the government, and if they die, they will receive a pension of more than 50,000 yuan.

Don't look at 50,000 is a small number, when Shu Han just entered the Black Iron City, a citizen of the Black Iron City, a month's income is only 300 yuan, this 50,000 is equivalent to thirteen years of income, this is not a small amount of money, although now the environment of the survival alliance has changed, and the monetary system has been reformed, after all, the entire survival alliance does not have so much gold to flow into the market, so the comparison between gold and money is gradually separated, of course, money is still linked to gold, After all, the national reputation of the Survival League is not so high, in this era, the country will collapse anytime and anywhere, Guangyuan is like this, and the Black Iron City is not like this, if paper money and gold coins cannot be directly exchanged, then soon the people will give up the use of paper money, so the two are linked.

But in order to meet the productivity, the ratio between gold coins and currency has now changed from one to one hundred in the Shuhan period to about one to five hundred now, and people's income has also increased, like a soldier, today's income can basically reach about two thousand yuan, so 50,000 yuan is equivalent to about two years of money, but this is only given by the government, and the army will also give about the same amount, and then under the Lijia system, each street committee will also compensate for the sacrifice of soldiers, about more than 20,000 yuan, Together, it equates to about five years of income, which is already a very high sum of money.

After all, now the Survival Alliance itself does not have so much money to be rewarded, which is also a matter of no way, and under the heavy reward, there will naturally be brave men, and there are not bad people in the army, some of them are for rewards, and more are for opening this channel, in this regard, Shu Han is actually guilty of them in his heart, after all, this time, ten deaths, there are very few people who can live, and it is okay on the hot air balloon, but if it is on the ground, It is impossible for Shu Han to organize a large-scale rescue team to rescue these people again, so in this matter, most of the people will never return, but there is no way, in order to open this channel, there must be sacrifices.

If someone is willing, then of course it is best, if not, Shu Han must also force some people to go up, this is no way to do it, for the survival of the alliance, it is necessary to have some people sacrificed, in this matter, there is no morality, no philosophy, only survival.

Soon, a team of thirty people was organized, and they would go into the forest with different audio equipment, including fifteen in the hot air balloon and fifteen on land, approaching in two groups in the direction of the monkeys, each of them carrying a pair of headphones with different audio, floating up and down fifteen hertz according to the original number.

In the eyes of scientists, that threshold is roughly in it, in the parting suburbs, Shu Han looked at these young or vicissitudes of life, the feeling in his heart is indescribable, he can only take a glass of wine and clink glasses with them one by one, looking at their gradually distant figures, Shu Han did not go, but asked people to bring a chair and sat directly on the side of the road, Chang Ke on the side said: "Führer, let's go to the city and wait." ”

"No, I'll wait for them here, and if it goes well, I'll be back in the evening." Because of the existence of that monkey, although this forest is very large, there are no fierce beasts, maybe there will be some wild beasts, but these soldiers are carrying guns, there will be no problem at all, back and forth, one day is enough, Shu Han wants to wait here for them to come back.

Chang Ke persuaded a few words on the side, and saw that Shu Han was very firm, so he stopped persuading, they were all people who followed Shu Han out of the iron mine, and they knew Shu Han's temperament very well, he was a very gentle person on weekdays, and he often joked with them, he didn't seem to have any principles, and he never regarded them as subordinates, but as long as it was something he identified, he would be very firm and unswervingly do it.

Shu Han sat here, others naturally did not dare to go, gradually the sun was slanting westward, the sun was setting, there were attendants on the side with torches and food, Chang Ke asked Shu Han to eat something, Shu Han really had no appetite and only drank a bowl of soup, he kept walking to the side of the road, wanting to occupy a wide field of vision to see the distance, and at the same time looked up at the sky, whether there was a hot air balloon flying back, everyone's mood was a little nervous, Shu Han had no appetite and others were the same, everyone knows that the longer the time, the greater the possibility of mission failure, At times like these, everyone is afraid.

At this moment, there was a sudden sound of horses' hooves in the distance, Shu Han immediately walked out of the tent on the side, looked into the distance, and several attendants on the side also immediately rode horses to investigate, the atmosphere of the entire camp was ignited, and soon, the fast horse arrived in front of their eyes, only to see that none of the fifteen people who went were lost, all of them came back, and everyone showed a look of surprise on their faces.

Shouldn't this be? In any case, there should be only one person who can come back, in heaven and on earth, after all, each of these thirty people carries a different audio, and only one of them is related to the monkey, and the others should all be hallucinated and lost in the forest, why did they all come back?

Shu Han was a little incomprehensible, and at this time, the knights on the horse finally walked in front of him, and Shu Han immediately asked, "What's the matter?" The knight looked at Shu Han and said, "My lord, we have been looking in the forest for a long time, but there is no monkey at all?" ”

Shu Han and everyone present couldn't help but sigh, it turned out that after these knights entered the forest, they immediately moved towards the place where the monkey was active all the year round, but when they arrived, they didn't see any trace of the monkey at all, everyone was unwilling, thinking that he was going to other places to move, so they scattered and searched near the forest, until the sun in the sky fell, and everyone did not dare to continue the forest activities at night, so they withdrew, which is why they came back so late.

Hearing the whole process they narrated, everyone was a little puzzled, and at this time, Chang Ke on the side said: "You say, that monkey, will it run away?" Everyone present was a little unconvinced, that monkey was so powerful, in the face of a group of ordinary people, he would run away? It sounds like a fairy tale.

"It's a bit of a possibility, although the monkey looks weird, but his IQ is not lower than others, after a few observations, I'm afraid I also noticed that we have noticed his shortcomings, this time I saw that our personnel were carrying new equipment, we thought we had found a way to solve his hallucinations, and it was possible to escape." One expert spoke, and his answer made everyone involuntarily believe that it was indeed possible to be true.

The monkey's IQ is so high, the illusion is the ability he relies on for a living, if this ability loses its effect, then all he has left is infinite strength, and it is natural to look down on it alone, but if you face the entire survival alliance, it is obviously not enough, so it does make sense.

However, Shu Han, who originally thought that the task would take a lot of time, suddenly realized that this task was automatically completed because of the monkey's cunning, and he was unconsciously a little incredible, and he immediately said: "What about the amethyst?" Have you found the amethyst? ”

After the mastiff died, there was a piece of amethyst, and at their last moment, they also relied on amethyst to greatly improve their ability, although now the survival alliance still doesn't know what this amethyst is, but obviously, this thing has a great relationship with the existence of the monster, if the amethyst is still there, then the monkey will really leave? Shu Han didn't believe it.

The cavalryman said, "I didn't see it, when we arrived, we saw potholes on the ground, we thought it was the monkey's footprints, but we didn't think that there might be amethyst." One knight said, and the other said, "I do see that there is a place where there is a deep depression, but at first I thought it was the place where the monkey put his stick, and I did not think that it might be the place where the amethyst was kept." ”

Although many people in the Survival Alliance know about Amethyst, after all, there are so many people involved in the rebellious hunting activities, and it is not unimaginable for the news to spread, but most people do not have a special understanding of Amethyst, which is completely a top secret within the Survival Alliance, even those in Guangyuan Country do not know.

Including the Holy Alliance itself, after the fierce phoenix was driven away, there may still be amethyst left in that land, but the strong nuclear radiation made it impossible for the staff of the Holy Alliance to enter at all, and Qiao Xuan issued a prohibition order, and that amethyst would obviously not be easily discovered.
