The integrated integrated wireless Internet root server system, such a long and difficult technical term, may mark a certain peak level that human technology has reached. Most people have never heard of its name in nuclear war.

In this broken era after the nuclear war, if aliens had not suddenly and incredibly traded with human survivors, at least for the expected future hundreds of years, this term could only stay on the paper of the materials that survivors had worked hard to preserve. It seems that before the war, survivors had never heard of such advanced network systems that could be used on a large scale without assuming network cables. However, since the Venus dared to include such equipment on the list of goods allowed for sale, it seemed to be enough to prove that this set of things had indeed existed in a top-secret high-tech laboratory on Earth.

According to the detailed description of product performance provided by the Venus, this wireless Internet system does not use artificial satellites, and covers a radius of 150 kilometers by a single machine, mainly due to the influence of the earth's curve, rather than the issue of transmission power. Of course, the effective range of this theory refers to the plain area with flat mountains, not the undulating peach blossom land. In the service area, just use terminal equipment with wireless Internet access functions, survivors can basically realize the same data exchange function as the global Internet in the pre-war era.

Regarding the nuclear war that still makes survivors dream back at midnight, it can't help but wake up from cold sweat and sweat, ruthlessly destroying human civilization. The few survivors also retreated from the information age of the global village to the 19th century. The living environment is in such a huge contrast, and people feel that life is inconvenient. Especially in terms of communication, they are almost unbearable. For example, in Taohuayuan, except for the old electronic tube radio station that Wu Han often fiddled with, there is no other communication tools that can be found at all. Usually, they can only rely on human power to transmit letters to achieve long-distance communication.

The urgency of restoring online communication is still second, at most it is a side effect of beating rabbits.

The core goal of this transaction with the Venus was discussed by the survivors after two group discussions, focusing on repairing damaged wind power plants.

If black crude oil is the blood flowing in modern industrial blood vessels, then there is no doubt that the power system supporting the brightly lit city is the neural network connecting this body. The wide range of power is something that everyone can witness. It can be said that cutting off power means nothing to do, and all household appliances will go on strike and close. Taohuayuan is based on wind power generation, and everyone also considers the stability and safety of power supply in an important position in the lifeline.

The wind power station, which was in great trouble, has experienced the heavy snow pressure and cold weather tests of the nuclear winter period. The subsequent floods were destroyed like a shattered destruction, and the infrastructure of the wind power station was even scarred. According to rough statistics, more than half of the wind turbines were completely damaged, and the remaining power generation and transmission and substation facilities were only simple maintenance and reinforcement. At present, the wind power station is still operating with hidden dangers. If these generators are unhappy one day, they may strike collectively at any time. Even if this situation has not happened, we must not forget that after the power station has been operating for a few years, the storage and substation system urgently needs to replace the electrolyte. Due to the insufficient chemical raw materials, Xu Changli has not been able to completely solve this difficult problem before.

Electricity is a prerequisite for maintaining the operation of the greenhouse system in Taohuayuan. Once the power supply of the wind power station is cut off, relying solely on those few diesel generators, at most, the final abandonment of the cave greenhouse system is almost an inevitable outcome that cannot be avoided.

The survey report compiled by the scientific research and industrial team in Wu Han emphasized that the crisis may come at any time, but he knew what the big problem was. Wu Han was also a good wife and couldn't cook without rice.

Before the arrival of Venus, Taohuayuan lacked professional maintenance equipment and spare parts, and even qualified maintenance personnel could not say that there was a comprehensive renovation. With Taohuayuan's own ability, if you want to solve this difficult problem, you have no hope for ten or eight years. However, the door opened by the Venus fundamentally ended the sword of Damocles hanging above the heads of survivors.

That order has been placed, but I don’t know when the many materials and equipment needed to repair the wind power station will be delivered. Even so, the dawn of hope is vaguely visible, and people have hope.

Deeply feeling that the opportunity was rare, Wu Han made up his mind to do a big fight, and found the maintenance manual and relevant technical information about the power station, and cast a big net among the survivors of the Peach Blossom Land to catch people.

Whether it is the individual boss who has worked in automobiles and home appliance repairs, or the university gangsters who have studied in the Department of Mechanics and Engineering at Pheasant University for two days, any one who has a little bit of a relationship with the word "mechanics" can be said to be one of them, and they have all been arrested. This is not the end. Wu Han unceremoniously imitates the most unscrupulous capitalists and requires everyone to study together for twelve hours a day, seven days a week. He is required to ask these laymen to fully understand the core technology of repairing wind power stations before the maintenance equipment is delivered.

Wu Han, who held the fork muscles in his hand, clumsyly imitated the slogans of his predecessors, and would rather call people and equipment than equipment and other personnel.

Hard work pays off. When the survivors were trained to the point of sorrow, they began to look forward to the stars and moon every day, hoping that aliens would deliver equipment and materials early, so that they would no longer have to be pulled out by Wu Han to practice every day until they were ecstatic.

At noon a week later, patrol personnel looking out in the surrounding areas of the valley rushed all the way and panted into the repair crash classroom converted from the conference room. They spoke without any use. Looking at the faces of the visitors with fear in surprise, Wu Han guessed what happened when he glanced at him, and immediately rushed out of the cave without saying a word. As expected, the elusive flying saucer appeared again above the Peach Blossom Land. The biggest difference from the previous ones was that the pile of cargoes that were nearly a hundred meters high below the flying saucer was even more eye-catching.

The survivors who came here earlier were all dazed at the spectacular scene. The first question that came to mind was how the aliens stuffed so many things into the not-so-big-looking UFO, and it was overloaded so much!

At the convergence of the blue light, the Venus who landed on the ground saw Wu Han appear and nodded at him, as if it was a kind of courteous greeting. Then, the Venus who was in charge of the weird tone of electronic synthesis said:

"The goods have been delivered, please accept it."

While Wu Han told someone to count the goods, he said:

"Because of climate, we will have to deliver the goods next year as soon as possible. Do you have no objection to this matter?"

The headed Venus was silent for a while, and later it turned back and communicated with several other companions. The humans not far away could not hear the conversation between them at all, and people could only wait for the results silently next to them. After a while, these Venus finally reached a consensus, and the Venus, who looked like a leader, spoke:

“…Yes, please hurry up.”

Hearing the sound, all the survivors of the Peach Blossom Land breathed a sigh of relief. It was said that this matter had ended successfully at this point, and we could shake hands and say goodbye with kindness. The problem was that Wu Han suddenly had an idea at this time. At that moment, he couldn't suppress his strong curiosity and said:

"Well, if you don't mind, I would like to ask, what do you need opium?"

The Venus opposite was silent for a while, and finally the Venus, who was the leader, spoke in a very perfunctory tone:

“…a hobby.”

It is obvious that Venus, who lack the patience to answer the questions of curious Earthlings, are reluctant to reveal too much information to the Earthlings. Perhaps for them, it is enough for these human survivors to help plant poppy and extract opium. As for other things, there is no need to let the Earthlings know. These Venus probably do not intend to give Wu Han a chance to continue asking questions. They immediately handed a metal disk the size of a palm, and did not forget to remind him:

"Phoneer. Gene binding is used, and you can call us."

As soon as Wu Han got this alien high-tech equipment, he could only helplessly watch the Venus flying saucer disappearing rapidly in the sky. After consciously hitting a soft nail, Wu Han could only rub his nose boredly. Then he cheered up and waved his hand to greet the survivors to start carrying the veritable and piled up goods in front of him. When these things were written on paper, they were just a line of words. When they became real objects in front of him, just sorting and placing them in a proper way, these things were enough to make people feel troubled for a while.

Excluding those small items of goods, they lined up in front of the survivors, and all heavy trucks powered by high-end hydrogen fuel cells are spectacular. These sturdy appearances are unparalleled, and all the red car front paints make many people recall the majestic posture of the Transformers brother Optimus Prime in the classic cartoon.

There is no doubt that the shape of the heavy truck is very eye-catching. The car lovers among the survivors can no longer hold it in. They surrounded them early in the morning and drooled at the cars. In private, they had already begun to discuss who would drive it to try the feel. This technology is so advanced that in the pre-war era, in addition to large auto shows, the electric-drive trucks that ordinary people would have to see on the road in more than ten years. It was the product of Wu Han and others' exhausting their minds to pursue the principle of maximizing interests. At the beginning, these people racked their brains to calculate the Venus people when formulating the purchase list!
