Fiction: Invincible Battleship Author: pearlfish sea Word Count: 5001

? After experiencing the assassination of Shao Zuo's plane, Yan Fei once again entered the mode of staying in Neverland. During this period of time, he did not go out at all. Although he was already a god-level master and had the ability to protect himself, he was not invincible. Therefore, for the sake of safety, he is determined not to leave his nest and not put himself in a dangerous situation.

Fantasy Island is the site of Yan Fei. There are monitors throughout the island. Under the monitoring of artificial intelligence "Fantasy", there is no secret for Yan Fei on Fantasy Island. So on Neverland, Yan Fei doesn't have to worry about someone planning him, he is absolutely safe here.

On the third day, whoever I was came to find Yan Fei and asked how I could retrieve my memory. So Yan Fei asked who I was. As a result, I didn't know any other clues except knowing who I was waking up in the basement of the Vatican. However, Yan Fei compared this time, and was surprised to find out who the time I appeared actually coincided with the time when I went to the Vatican to **** the papal scepter. That time I blew up the Vatican, so whoever I am in the basement woke up, and then left the Vatican. Speaking of which, who I am really has a great relationship with Yan Fei, who I find Yan Fei still has some reason.

Yan Fei guessed who I might have something to do with the Holy See in history, so she began to collect the Vatican scriptures, and wanted to find clues about who I am from the Vatican scriptures. What disappoints Yan Fei is that no matter what he looks for, there is no record of who I am in the Vatican scriptures, and no similar record is found.

In desperation, Yan Fei had to start with the body of who I am, and wanted to understand who the body of me was and what went wrong, so the situation of amnesia appeared. So Yan Fei brought me to the Fantasy Island Terminal Hospital, using the most advanced detection equipment of the Fantasy Terminal Hospital to perform a variety of detailed tests on his body, and obtained a large amount of physical test data. In order to get more information, Yan Fei also asked me who provided my own blood sample, hair sample, and body muscle tissue sample.

Although I saved Yan Fei, Yan Fei couldn't believe who I was. For the sake of safety, Yan Fei didn't take who I am directly to the Neverland Laboratory under the ground. He conducted a direct inspection. Because Yang Qi's laboratory is the most valuable place in Neverland, once people who have not proven their relationship with ourselves are put into this laboratory, the consequences of problems will be disastrous.

However, Yan Fei quickly sent the body test data, blood, hair, and muscles of who I am to an underground laboratory, and asked Yang Qi to research who is my physical condition. Yang Qi was doing more important scientific research, but after knowing who I was and becoming 9999 bats, Yang Qi immediately became interested and shifted his research focus to who I am.

When I came to Neverland, I behaved very quietly. Although he had amnesia, his body maintained an instinct that made him behave politely, like a real gentleman.

Who I am doesn't like to take care of him, he usually prepares food by himself. And he doesn't like surfing the Internet and watching TV, and he doesn't like leaving the villa where he lives. Only in the evening, who am I will come out for an activity, but this activity is not very long. During the day, everyone who I am sleeping at home does not appear in the sun at all.

Who am I? Day and night, plus his ability to turn into a vampire bat, these two characteristics make Yan Fei suspect that he is a legendary vampire in Western history. But only when the results of Yang Qi's research come out can we know who I am or what.

During this time, when I was out, Yan Fei would communicate with him about the knowledge and understanding of heaven and earth. Who I am does not know that the power he mobilized is heaven and earth aura. He uses these heaven and earth aura as if it were the instinct of the body. He can do it as long as he thinks about it, so Yan Fei did not find more from who I am to use heaven and earth aura. Approach. However, after a few discussions with who I am, Yan Fei has more feelings about the power source of the god-level master. This feeling has made Yan Fei's strength soar, almost a step every day ...

Under Yan Fei's instructions, Dream Island changed its thinking of work, no longer pursuing the goal of earning the highest profit, but letting more people work and live on Dream Island while earning more profits. So Neverland has been building more processing plants recently, while hiring more production workers. Some high-tech products on Neverland, in addition to the most core steps and processes, all other steps will adopt manual production methods.

For example, the super high-energy battery pack of Neverland, the core battery stock solution and the process and process of adding black gold elements are all carried out in a fully automatic production workshop under the ground, and the entire process is kept secret. But when the super high-energy battery is inspected, packed, sorted, and transported, it is all performed by workers from outside processing plants. In this way, not only the ultimate secrets of Neverland products are still guaranteed, but also a large number of workers can be supported by the secondary processing of these products.

It is with this huge change that in the past, large factories on Neverland have sprung up like mushrooms. Even on the newly developed 3,000 square kilometers of land, a large number of factories have also been built, which will be used for the production and processing of Neverland products.

During this time, the development of 3,000 square kilometers of new land has entered the fast lane. And over time, the white mist over the new land is becoming thinner. Yan Fei performed simulation calculations using the auxiliary brain, and found that up to three months, the white fog over the new land would completely dissipate, and then the 3,000 square kilometers of new land would appear in front of the world.

Now Yan Fei and Neverland are extremely powerful, and there is no need to worry as much as before when 202 square kilometers of land in Neverland appeared to the world. Nowadays, unlike in the past, Neverland is not afraid of the trouble of others coming to find themselves. As long as Yan Fei is still there, Neverland is indestructible.

Time passed quickly, and two months passed quickly. In these two months, Neverland has changed a lot.

First of all, the long-awaited Fantasy Island Gambling Group has begun operations, and the large-scale casinos of Dream Island have officially opened to the public.

This is a key development project of Neverland, so before it officially opened, Neverland analyzed and screened the source of passenger flow of the casino, and finally excluded white people in the Western world and black people in Africa, but only defined casino customers as Huaxia and the surrounding countries are also members of the Huaxia cultural circle. Then, in the publicity, focus on the publicity of these countries.

So before everyone responded, the domestic networks of these countries were overwhelmingly all about publicity advertisements about the Fantasy Island Casino.

Huaxia previously reached an in-depth cooperation agreement with Neverland, which not only includes the technical support provided by Neverland to Huaxia, but also provisions that allow Huaxia personnel to go to Neverland for entertainment activities. Therefore, when it was discovered that Fantasy Island advertised casinos in Huaxia Network, the relevant management departments opened their eyes and closed their eyes, and did not manage this at all.

China also understands that China's state-owned gambling tradition. But now the domestic management is too strict, which suppresses the fun of some gamblers, so that sooner or later there will be problems. So I didn't bother to see it, so I just let this group of people who like gambling go to Neverland, after all, Neverland is their own, and in the end, the water is not flowing out.

It is precisely because there are a large number of advertisements, and the procedures for Huaxia people to come to Fantasy Island are very simple. Therefore, on the first day of opening of the large-scale casino on Fantasy Island, a lot of curious Huaxia people came to Fantasy Island. See for yourself the magic of modern casinos. Here they are God and can gamble unscrupulously without fear of being caught.

Other people's minds are not put on the casino at all, their purpose is the red light district next to the casino. However, these people are destined to be disappointed. The preparations for the Red Light District have not been completely completed, so the Red Light District has not yet been opened to the public. This time, people can only gamble this time, and they can't go on the hunting tour of expectations. Fortunately, as long as a few months, this red light district will be officially opened. At that time, not only can you gamble on Neverland, but you can also enjoy the indescribable tenderness.

As a large number of people entered Neverland to visit and gamble, it also spawned an affiliated service industry. In order to provide life services for these people who come to Neverland, a lot of new hotels and restaurants have been built on Neverland in a short time, plus other service industries. In a short time, the number of people on Neverland Surge.

Every day, not only are the planes flying to Neverland fully loaded, but the cruise ships at sea are also full. Neverland has begun to replace popular attractions in other countries in the world, becoming the most popular destination for Chinese people ...

Secondly, Yanfei has produced ten sets of equipment parts for super nuclear power plants by using underground intelligent production workshops. These intelligent production workshops are completely controlled by artificial intelligence “dream”, with extremely high work efficiency and sufficient raw materials, so they can complete the production tasks in a short time.

Over the next time, Neverland recruited a large number of technicians, and then trained them to let them know how to install these equipment and inspect and maintain them. After everything was ready, under the transportation of several large freighters, this kind of super nuclear power plant equipment that can change the current energy pattern was arrived in Huaxia, and then started the intensive construction work.

After the construction and power generation of these ten super nuclear power plants is completed, Huaxia's energy structure will be completely changed. Since then, Huaxia will never have an energy shortage. With these super nuclear power plants, China ’s large number of thermal power plants will be officially closed, and true clean energy will be used from then on.

The Huaxia Energy Revolution is equipped with self-driving electric vehicles. With the efforts of Yang Qi, Neverland has designed several new self-driving electric vehicles, and their design drawings have been confirmed by the technology deduction system, which proves that Their safety and reliability.

After the technology was confirmed, Neverland began to communicate with Huaxia's auto manufacturers, and it was necessary to improve their traditional automobile production lines and use these new automobile production lines to produce Huaxia's own self-driving electric vehicles.

To achieve this, Neverland used the recovered carrier rocket to launch another 36 global positioning satellites in one shot. The 36 global positioning satellites will form an independent network dedicated to navigation for self-driving cars jointly produced by Neverland and Huaxia. In some pilot cities, a large number of charging stations will be installed at various gas stations, and a large number of data sensors will be installed on the city's main roads to ensure that autonomous electric vehicles can safely travel in cities.

Finally, the commercial large-aircraft project of the cooperation between Neverland and Huaxia also officially entered the design stage. China knows that Dream Island has advantages in the design of large aircraft, so it handed over the design of the large aircraft to Dream Island. With the efforts of Yang Qi, a brand-new large aircraft has been designed and also passed the technology deduction confirm. Therefore, as long as each component is produced, Huaxia can assemble large commercial aircraft in domestic factories.

On the secret front, military cooperation between Neverland and China also began to bear fruit. Various large ship aircraft auto engines and high-energy battery packs provided by Neverland have begun to appear on Huaxia weapons and equipment, and have shown powerful performance, which has greatly enhanced the power of Huaxia weapons, slowly catching up with the world's most from the previous catch-up state Advanced level.

During the cooperation of Dream Island, Huaxia has discovered that Dream Island is using steel and cement for infrastructure construction. After knowing the various properties of steel and cement, Huaxia is very happy. They are the largest infrastructure country in the world, and it is just when a lot of cheap steel and cement are needed.

They immediately began to try to introduce this kind of steel and cement to replace the use of some steel during infrastructure construction. Then they discovered the strength of steel and cement. The key is that the price of steel and cement is much cheaper than steel, so China has a big The idea of ​​using steel and cement in the area, after all, can not only be a better quality of their infrastructure, but also save a lot of construction vehicles.

You should know that Huaxia has always lacked high-quality iron ore, but it has been restrained in the procurement of iron ore. So when they found steel cement that could replace steel, they promoted steel cement. In this way, Huaxia not only got rid of the dilemma of being restrained by people on iron ore, but also obtained cheaper and better quality raw materials for construction than steel.

Previously, Yang Qi had speculated that there may be a special device in the underground rocks of Neverland. This device can convert the outside world's aura into mysterious energy. This mysterious energy combined with the underground rocks and soil will turn them into hard. Underground rock, and has some unique characteristics of steel.

So in order to find this possible underground equipment, Yan Fei has been digging underground. During this time, Yan Fei had dug 3,000 meters into the ground. These underground rocks are inherently very hard, and the harder they go, the harder they are. So even though Yan Fei has indestructible drone shock waves, his digging speed is also very slow.

After reaching a depth of 3,000 meters, Yan Fei's daily digging speed is less than 50 meters. Judging from the progress of this excavation, it takes a long time for Yan Fei to find the possible underground device.

During the underground excavation, Yan Fei had a deep understanding of the hardness of these rocks. After reaching a depth of 3,000 meters, the hardness of the underground rocks here has exceeded the hardest steel in the world. In other words, if these rocks are used to build a house, it will be attacked by large-caliber artillery shells. This house can also stand upright to ensure the safety of the people inside the house.

Not only that, Yan Fei also found a wonderful use. That is, he can dig some large warehouses underground, and then keep some items in these warehouses. Underground rocks are very hard, so even if Neverland is attacked by a nuclear weapon, the contents of these underground warehouses will not be damaged in the slightest.

The exploration of the underground rocks of Neverland is a long-term process, and no results can be obtained in the short-term. However, Yan Fei believes that as long as he persists, he will be able to discover the hidden secrets under the Neverland.
