It was the second year after the First Legion started its plan to visit the Loulan Star Territory.
A top-secret project is underway in the Presidential Palace of the Earth Federation, which was named the Interstellar Great Wall Project by Lin Zhen.
This plan is intended to build an interstellar Great Wall to eliminate the potential threat to the Federation from the Babavi Empire, ensure the stable development of the Federation in the next fifty years, and lay a solid foundation for the subsequent capture of the entire Orion Arm.
Everyone knows that for a fourth-level civilization, strategic depth is meaningless. After all, the jump engine is a bit cheating, making it impossible to effectively defend. This is why the Babavi Empire has banned the sale of jump engines as equipment.
After the fourth-level civilization, ensuring the security of its own territory has always been an important issue for the human federation. For more than ten years, no effective measures have been developed.
It wasn't until the alliance joined the Xio Alliance that they saw [Jump Blocking Technology] and [Jump Blocking Countermeasure Technology].
Since it is only a technology for the early stage of level 5 civilization, it can be done by a level 4 civilization with all the technical information.
Many people may say that even with technical information, it is impossible for a fourth-level civilization to understand the technology of a fifth-level civilization. In fact, this is a wrong probability.
Let’s talk about how a level-4 civilization can become a level-5 civilization. Isn’t it necessary to develop the iconic technology of a level-5 civilization before it can be officially promoted to level 5?
If a civilization cannot research cross-level technologies, then all civilizations will not need to advance, let alone now that humans have all the technical information.
The most important thing is that humans, under Lin Fan's cheating, directly developed brain development potions. It can be said that even the fifth-level civilization does not have such perverted things.
Therefore, after Bai Zixuan's team arrived, the first task that Ed gave Bai Zixuan was to lead his team to understand these two technologies.
After spending a whole year, Bai Zixuan and his team have achieved good results.
Although the test equipment produced does not reach the range of 1 light-year in the technical description, it does reach the range of 0.79 light-years, and is fully ready for mass production and use.
At the beginning, Lin Zhen and Aide's plan was to install a transition blocking device in each star system and arrange a large number of detection devices within a range of 0.79 light-years around it.
In this case, no matter which star system the opponent wants to attack, it will be affected by the transition blocking device at a distance of 0.79 light-years and exit the transition state.
Then there are only three choices given to the invading civilization!
First, it will take several years to slowly complete the 0.79 light-year journey at sub-light speed, and in the process, it will inevitably be detected by the numerous detection equipment deployed by the Federation.
The second one is to jump to the neighboring star system, and then follow the same star path as the third-level civilization, provided that the neighboring star system is not equipped with jump blocking equipment.
The third is to retreat!
This was the serial fortress plan originally drawn up by the two people. They would directly build all the star systems in the territory into fortresses, making it impossible for invaders to eat.
However, with the expansion of human territory, and now there is such a huge Loulan Star Territory, the two people's ideas changed and became even crazier.
As a result, an interstellar Great Wall project emerged that shocked everyone. Anyone who had seen the contents of this project was shocked by the generosity of this project. Many people even directly called Lin Zhen and Ed two lunatics.
Yes, it's really crazy.
How crazy is it?
As we all know, the Orion Arm is about more than 20,000 light-years long, and its width and thickness are much smaller, but it is still thousands of light-years long.
Lin Zhen and Ed planned to use jump blocking equipment to build an interstellar Great Wall with a thickness of ten light years on this arm.
According to calculations, if the Human Federation wants to complete this plan, it will need to manufacture at least 40 million jump blocking devices for network deployment. Once completed, the Orion Arm will be completely cut in half.
From then on, if the Babavi Empire wanted to invade human territory, there were only two ways.
One is to slowly cross these ten light years through a sublight engine, which is expected to take at least 30 years!
The other is to travel honestly to the Star Path, but this will also face the defensive advantages of the Star Path of humans. If you want to break through, you have to pay at least 5 or 6 times the battle damage of humans.
Even if the Babavi Empire obtains [Jump Blocking Countermeasure Technology] from the Vera Alliance, it will be useless. As mentioned before, [Jump Blocking Technology] and [Jump Blocking Countermeasure Technology] are used in pairs.
After all, any civilization using [Jump Blocking Technology] can set its own blocking frequency. Only by knowing this frequency and setting it in the jump blocking countermeasures device can the normal jump pass.
This blocking frequency is infinite and can change at any time, making it almost impossible to crack it.
The best thing about this plan is that according to mankind's understanding of the Orion Arm, there is a section of the Orion Arm that seems to be cut off. There is no star system within the entire ten-light-year length.
A year ago, Lin Zhen secretly sent out many exploration spacecraft, targeting this starless area.
Not long ago, the news it sent back was even more surprising. In that blank star region, there was only one star road connecting the star systems on both sides.
In other words, as long as humanity's Interstellar Great Wall plan is completed, this Star Road will be the only way for the Babavi Empire to invade human territory. As long as humans deploy heavy troops here, they can ensure the absolute security of the entire territory behind them.
At that time, a very interesting situation will arise. Human beings can use the jump blocking countermeasure device to cross the interstellar Great Wall at will, and attack the Babawi Empire at any time and anywhere!
However, the Babavi Empire could only reach the human territory through the only Star Road, which took more than three years, and it also had to face the heavy human troops with extreme defensive advantages at the exit of the Star Road.
Now, the entire Federation has fully launched the Interstellar Great Wall Project, frantically arranging mass production lines in various star systems, and is expected to complete the production of all 40 million sets of jump blocking equipment within five years.
As for the resources required, Lin Zhen had already made a plan. The current reserves of mankind and the resources contributed by affiliated civilizations are enough for mankind to support this construction plan for two years.
In another year, the third federal army will be formed. Their first task is to follow the steps of the first army into the Loulan Star Territory and clean up all civilizations that are evaluated by the first army as having insufficient potential.
Spanning a full 500 light-years of star field, the internal resources are not enough to build an interstellar Great Wall. There is no problem in building a few more, and this is only based on plundering the mined resources of these civilizations.
As for untapped resources, there is still a huge surplus if 100 are built.
Therefore, this is a great purge that affects the entire star field, and it is also a great plunder. This is the main theme of the interstellar era.
