The ancestors of the Eden world were pacifists and environmentalists, and when they landed in Eden, they signed a charter and vowed to jointly maintain the peace and environment of the Eden world.

More than two hundred years have passed, and although the descendants of the humans in the world of Eden do not fully respect their ancestors, some traditions remain.

For example, the policy of small countries and widows, never establish a state of government, the largest state is only the city-state, and send representatives to form a coalition of city-states to maintain peace. Although wars have also broken out between city-states, in terms of scale, the largest is only a brigade-level confrontation, so it seems that the policy of the alliance of city-states and small countries and widows is still relatively effective in maintaining peace.

As for environmental policy, it is similar to the benefits of maintaining peace, after all, humans are the most capable of creating garbage.

However, out of the principle of economy and environmental protection, the ancestors strictly limited the use of metal to make communication relay towers in the constitution, which greatly limited the communication between the city-states. Instead, the use of communication balloons, and later due to the development of Eden World Energy, humans began to try new ways to relay communications.

There are no fossil fuels such as oil and coal in the world of Eden, but there are more interesting energy ores, one of which can easily create lift (only in the atmosphere), which is completely the biggest blow to aerodynamics, since it can use the levitation engine to create lift, then traditional aerodynamics are not so important. Since its inception, the suspension engine has been developing in the direction of the two extremes of heavy duty and ultra-light. Among them, the heavy-duty suspension engine was frozen by the city-state alliance because it was suspected of being used in the military field, while the ultra-light one was considered to be less lethal and was proud to continue to develop, and the result was that the steel city-state took advantage of the loophole and invented the air ** This kind of big killer, and so the city-state alliance found it was too late, so it had to make up for the restrictions and formulate a restriction law, such as the number of air ** production to be restricted, the inventory to be supervised, and not allowed to continue to develop the suspension engine and so on.

However, no matter in that world, as long as there are advanced intelligent life forms, the development of science will never stop because of some kind of ban, which was not possible in the dark medievals of the earth, but Eden could not do it either.

After the ban on weapons research, the ultra-light suspension engine was used in civilian communications, but the communication repeater with pure metal shell and built-in suspension engine was more expensive than the traditional communication balloon, and still needed a tow rope for ground fixation, which did not seem to have many advantages.

By the way, the Ark Alliance city-states are currently in the leading position in the research of communication repeaters using ultra-small suspension engines, while the steel city-states, the earliest birthplace of ultra-light suspension engines, have adopted a simple and crude approach to solving the problem of communication relays. Isn't it forbidden to build all-metal communication towers? Well, I'll just build a reinforced concrete building, which can also be called a military fortress, anyway, the communication relay needs personnel to maintain and guard.

So while each telecommunications fortress was expensive, it gave the steel city-state an excuse to build a military base.

However, from the practical point of view, the communication building of the steel city-state is stable and powerful, which is far better than the communication balloon and the cardioid-shaped suspended metal communicator, and the disadvantage is that in addition to the huge cost, it is not flexible to use and deploy the balloon and the suspension communicator.

After the balloon at the communication station of the expedition was destroyed by the man-eating bird, some people once proposed to switch to an all-metal communicator with a suspension engine, but some people raised concerns - although the defense of the metal communicator is stronger than that of the balloon, it still needs to be fixed on the ground, and if the man-eating bird attacks in a big way, regardless of casualties, the piranha has enough explosions to destroy the all-metal communicator, and even the communication station, even if there is a drone escort provided by the Ark Alliance, and that will 100% cause the confrontation to escalate.

At this time, even the most militarily powerful steel city-states did not want war to break out immediately, not only because their ancestors were pacifists, but more importantly, through the research of autonomous combat robots and man-eating birds that attacked the fortress town, their masters' military and technological capabilities far exceeded those of all city-states.

No one wants to fight a war with no chance of winning, unless he's a madman, so it would be nice if someone could come up with a way to fight the man-eating birds effectively without exacerbating the conflict.

Fortunately, this man was found by Ah Jun, and secretly sent him back to the base camp, entrusting Irina to support and take care of him.

This man is Mr. Copper.

When Mr. Copper's communicator prototype pieced together from scrap parts was lifted into the air, it didn't cause too much of a stir, especially the representatives of the Ark Alliance, who thought that this was nothing remarkable, although the ultra-light suspension engine was forbidden and could not be further studied in terms of power, but it should be allowed to be produced and used, and in the city-state of the Ark Alliance, it was easy to get a relevant experimental license, and even received official support. Therefore, the representatives of the Ark Alliance looked down on the communicator that Mr. Copper had cobbled, and claimed that this quality of something could be easily made in his garage by even a smart high school student in the Ark Alliance.

However, when the representative saw another sample of Mr. Copper, his jaw almost fell to the ground in surprise.

Because this communicator that can levitate in the air does not need a leash!

Others were just as surprised when they learned the news.

And the representative of the steel city-state committed suicide by drinking a bomb that night. He repeatedly abused his power, first put forward the first proposal, and then applied for approval of the immigration of Mr. Copper's family, and more importantly, Mr. Copper actually made up this thing, although it was only an immature sample, but he knew that because of his own problems, he let go of such a super talent, and what was waiting for him after returning to the city-state.

Mr. Tong felt very guilty about Mr. Tsugi's suicide, but he didn't have time to feel guilty, because what happened next really made him have no time to deal with it.

Many city-states sent him immigration requests and made many promises, especially the representatives of the Ark Alliance, and the prices offered were unbelievable.

But Mr. Copper kept his promise and decided to emigrate to the metropolis, eventually settling in Fort Town. During the period when he made the prototype, the town of Fortress had done a good job of receiving it, and the customs had also made a special exception, Mr. Tong's family of seven had successfully come to the town of Fortress and lived in a temporary settlement - a nice small hotel, and also enjoyed various ticket coupons, food stamps, free skills training schools and other benefits.

In the competition for talent, Fort Town adheres to a forty-year tradition and has not yet failed.

In the face of the temptations of various city-states, Mr. Copper has actually wavered, after all, some promises are too tempting. So Mr. Tong wanted to talk to someone, and he finally felt that it was best to talk to Ah Jun, after all, Ah Jun was the first person to appreciate him, believe in him, and create opportunities for him, it can be said that without Ah Jun, there would be no Mr. Tong today.

So Mr. Tong went to the hospital, but the people at the hospital claimed that Ah Jun had never actually been to the hospital.

How is this possible? I had sent Chief Ah Jun to the hospital myself, and I had seen him in Irina's office after that.

So Mr. Tong went to look for Irina again, but Irina also said that Ah Jun had been fighting against man-eating birds in the camp of the hiking detachment and had never been hospitalized.

Mr. Copper seems to understand a little, Irina doesn't tell him, obviously she just doesn't want him to know something, but these things are not a secret in the world of Eden, they are nothing more than mutants.

Mr. Tong guessed that there must be a mutant next to Ah Jun, and this mutant has the ability to change his appearance and remind him, and who this mutant is is obviously a secret.

Well, a secret is a secret, and now that he's gotten so much, Mr. Copper certainly doesn't want to lose it by satisfying that little curiosity.

But the truth is reasonable, this hurdle in my heart still can't be overcome, and at this time, the transport boat to and from the front returned to the base camp and brought Mr. Tong a handwritten letter from Ah Jun.

The letter was not long, only a few words.

The letter reads: "Mr. Copper, no matter what choice you make, I will respect it 100%, the only request is to ask you to make a practical product as soon as possible, whether it is me, or your former comrades-in-arms, we are looking forward to your success." ”

Mr. Tong is a very affectionate person, he read this letter four or five times, and then he put down his distractions and devoted himself to the research and development of new samples.

The progress of the research and development of new products has increased a lot, although Mr. Copper has rejected many city-states' requests for immigration and technology transfer, but all city-states are currently facing a common enemy, so after everything is spread out, they all sent assistants to Mr. Copper's studio, and provided more and more advanced experimental materials, especially the Ark Alliance, which actually provided two new metal communicators.

Although the assistants sent to Mr. Copper's side by various city-states are more or less espionage, these people are indeed the leaders of the industry, and the joining of these people has turned Mr. Copper's studio into a real research institution.

However, as the days went on, some people developed a disdainful attitude towards Mr. Tong's abilities.

"He's not really remarkable, he's not professionally trained, his skills are rough, it's just that he dismantles the mechanical parts and puts them back together. There are a lot of things he does, and I can do better. ”

When this gossip reached Irina's ears, Irina only smiled faintly and said, "Speaking of which are highly educated, haven't you heard the story of Columbus erecting eggs?" ”

Sure enough, when Mr. Copper assembles a communicator that can actually fight the man-eating birds, he once again shakes the entire base camp. Many of the city-states' assistants exclaimed, "Why didn't I think of such a simple and crude approach?" ”
