At the end of the old Western calendar, human beings finally broke through the shackles of gravity and successively built huge artificial complexes - satellite colonies on the gravitational equilibrium point of the earth and the moon. Since then, mankind has entered the cosmic era and entered the new Western era......

In the 179th year of the new Western calendar, two centuries have passed since the replacement of human beings, and human beings have begun to colonize the universe, but people's lives are not much different from the old Western calendar around the beginning of the 21st century.

The biggest reason is because in the past 200 years, two meteorites have fallen, which has caused huge blows and losses to mankind, and even used this as a reason for the outbreak of the Third World War.

As a result of the Great War, the World Coalition Government, also known as the Earth Federation, or UGE for short, was born.

The world finally became one in this era, and the original division of countries and armies completely disappeared, leaving only the original regional division, such as the Japanese zone, the **** zone, and so on.

In the same year, a meteorite named Meteor 3 fell on the Marquesas Islands, causing great damage and damage, but it was not a densely populated location or center at the place where it fell, so it did not cause any unacceptable damage to the earth, society and human beings.

However, will the fall of this meteorite really have no great impact on the earth humans in this plane?

Dr. Bian Zoldak, director of the Tesra Institute, discovered EOT (ExtraOverTechnology) technology and alien aggression ambitions for the Earth in his analysis of meteor 3 that fell to Earth, and called on the federal government to strengthen its own strength to resist the alien invasion.

But the federal government was silent on the matter, and many high-ranking officials even began to ridicule the research team, led by Dr. Bian.

The Pluto Domain incident, which broke out at about the same time, slapped all the higher-ups who had laughed at Dr. Bian.

The first long-range cosmic deep space exploration battleship Wyvern, which was used by human beings to expand their living space, was attacked by an unknown mobile weapon group when it just sailed out of the outer space of Pluto in the solar system. The super-large battery that was sent out of the battleship was surrounded by many enemy planes and was almost paralyzed. Lieutenant Commander Taitetsu, on the advice of his adjutant Lieutenant Commander Xiuen, promptly recovered King Relige and detached him from the area.

Although the Wyvern successfully returned home, unfortunately, this human voyage plan ended in failure.

However, this incident really proves the existence of aliens and illustrates the hostile attitude of aliens towards earthlings.

But for various reasons, the Federation has not released information about aliens. Among them, there are even some high-level people, who continue to live a rotten life in panic.

The deeper reason is that I won't tell you that the special assistant to the president of the Federation is an alien.

As for why, after attacking the Wyvern sent by Earth, a diplomat was still sent to be in charge of liaison......

Now that I've told you all this, what are we going to talk about next in this story?

However, the federal government established an EOTI agency headed by Dr. Bian for the purpose of studying EOT technology, and established an EOTI Council to regulate EOT technology.

As the research deepened, some members of the council began to pessimistically believe that there is no future for mankind, or that in the future, human beings will have to migrate to other planets if they want to survive.

Dr. Bian, on the other hand, put forward the main battle argument that "there is no escape for mankind" to oppose the pessimistic argument of the pessimists. and began to secretly prepare for the establishment of a combat organization dedicated to fighting aliens, DC (DivineCrusaders).

But not all federal tops are rotten. Based on the EOT technical research report submitted by Dr. Bian, the federal military officially began the expansion program and submitted the standard requirements for a new generation of combat weapons to all military-industrial enterprises:

It must be a humanoid weapon, with movable limbs that can be indistinguishable from humans, and can be used in different types of weapons according to needs, and have a long enough sustained combat time......

These complex and difficult requirements are the bare minimum technical requirements that humans must meet if they want to resist an alien invasion after studying the technical report.

At that time, Mao's Heavy Industries, which was in trouble, regarded this bid as the final challenge. Almost all the assets of the entire enterprise are invested in the research of new weapons.

After the efforts of most scientists on the planet and the use of some EOT technology, an upgraded version of the conventional nuclear fusion engine, the plasma engine, was completed.

This made it possible to create PT (Personal Trooper), a lone hussar.

At the end of the 180th year of the New Western Calendar, Mao's Heavy Industries finally completed what can be said to be the first PT in history: PTX-001 Gespenst before exhausting its last assets and the last bit of time, and won the first place in the bidding with an absolute advantage, and won the nod of the federal military.

Taking this opportunity, Mao's Heavy Industries has successfully completed its rebirth and become one of the largest military enterprises on the planet.

But the undead also exposed quite a lot of problems in the test. For example, it is impossible to fly in the atmosphere, can only jump and glide briefly, and the accuracy of holding weapons through the manipulator is not high.

Therefore, in response to these problems, Mao's Heavy Industry has carried out corresponding transformation of the three trial machines produced. The No. 1 airframe, numbered PTX-001, was given the name TYPER (Repidity) due to its enhanced mobility and extended maneuvering time. The second PTX-002 is equipped with powerful built-in armament and reinforced armor, and is named TYPES (Strength). As for the No. 3 PTX-003, it is equipped with various detection equipment and data recording equipment, and exists as an experimental data collection machine, and is named TYPET (Test).

By the way, the upgraded version of the plasma engine, the invention of the plasma reactor, also allows the Undead S to be used without barriers and equipped with its own powerful armament. And it made it possible to give birth to super series bodies such as the G series in the later period.

People who like science fiction works, especially machine warfare, should understand one thing: the strongest mechs come from trial machines.

And these three prototype machines manufactured by Mao's Heavy Industries at all costs, although they can be called the ancestor level PT, but their various body data have reached and surpassed the third-generation body in the later period, and even won the title of "legendary ancestor body" in the future!

Because three undead were tried at the beginning, and they were specialized into close combat, artillery warfare and test machines, so this time the habit was passed on, and all the trial machines of Mao's Heavy Industries will be built into three, and they will be strengthened and named accordingly.

However, as a humanoid mech, it is necessary to minimize the burden on the driver as much as possible if it is aimed at mass production, so the PT's movements need to be supported by a large enough operation database.

As a result, the special combat skills training team composed of six of the best pilots of our time was established in the early 181 year of the New Western calendar. Mao's Heavy Industries also handed over Undead R and Undead S to the training team, and Undead T was sealed into a warehouse after collecting enough data.

As a team composed of the trump cards of aces, the teaching team has achieved achievements that can boast of future generations. They completed a huge database of moves and successfully explored the various tactical uses of PT.

It can be said that without a special combat skills training team, it is absolutely impossible for PT to become the main combat weapon of the new generation!

But time passed, and at the end of the 182nd year of the New Western Calendar, the captain of the teaching team, Colonel Kawi Raou, disappeared into the universe along with the undead S he was riding.

Also at the end of the 182nd year of the New Western calendar, in order to continue to expand their advantages and seize the market in the later period. After the completion of the official launch of the three trial machines, Mao's Heavy Industries has begun to design two new PTs, namely the PTX-004 Ranger focusing on artillery warfare and heavy armor, and the PTX-005 Boar focusing on high-performance mass production machines.

However, what the Federation needs now is a mass-produced airframe with high versatility and cost-effectiveness, and the PTX-004 Ranger, which focuses on artillery support, has naturally dismounted, and only a few bases and special forces have reluctantly purchased a few units due to the needs of future missions.

The PTX-005 Wild Boar is completely because of the pursuit of high performance in mass production, and as a result, its operation difficulty is too great. Although it is nothing for an ace pilot, as a mass production machine, this can be said to be the most fatal shortcoming.

As a result, the researchers of Mao's Heavy Industries abandoned many wonderful ideas and began the manufacturing plan of three PTX-007 Undead MK-II prototypes with the goal of mass production based on three prototype machines.

At the same time, as a technical discussion and reserve, the transformable body: PTX-006 Raptor also began its own manufacturing program.

Because of the disappearance of the captain, the teaching team was officially disbanded in early March 183 of the New Western Calendar, and after completing the last dinner with the senior management of Mao's Heavy Industry in a luxury hotel in the **** magic capital, the members who had gone to various units and departments to report officially separated and moved towards their respective futures.

And a report on the monster was submitted to the presidential palace. But again, the federal government has no intention of making this report public, even if an entire reconnaissance team is killed because of those monsters.

However, research on it is impossible to halt, but most of the official scientists at this time have joined the EOTI organization to focus on the study of EOT technology. The most powerful scientific research facility on Earth, the Tesra Institute is working on the design and development of a space Noah-class warship.

Therefore, in the end, the research on the monster named "UNDEMON" was handed over to Mao's Heavy Industries, which was in the limelight.

As a result, the surface identity is Mao's Heavy Industry New Technology Theory Verification Research Institute, but inside it is a special research institute for UD monsters, a large-scale research institute with complete functions, which was quietly established in the western wasteland of the Tian~ Dynasty.

But only a few people know how deep the water really is in this institute. And what kind of existence is sealed under the ground of this research institute......

Why should private companies directly participate in what can be said to be the highest level of secrecy, and replace the official as specialized research institutes?

You only need to know that in this world, even Killiam, who is a guest from another world, can become a member of the Federal Intelligence Department, and you will understand how inclusive this world is!

As for the top person in charge of this base?

Naturally, we call ourselves the owner of the Wanshiya, who has a good understanding of the native species, and has mastered the technology of sealing the space passage!

So, in the future when the direction of the world has begun to deviate from its own trajectory, where will this research institute that should not exist take the world?

But the only thing that is certain is that the familiar smell, the smell of war, has long since spread. And this time, there is no one to escape, no one to hide, the only thing to do is to fight back and exchange your own hands and blood for the right to live.

How much time does humanity have until the Last Judgment comes?
