Although he already has some understanding of the battle situation, Yang Yi's understanding of the situation of the Human Federation is still not clear enough. After Yu Mingzhen made a report, Yang Yi knew that the situation of the Human Federation was so dangerous that it was on the verge of defeat.www.biquge.info If he hadn't rushed back, maybe in ten years, twenty years at most, he would have been defeated. Ten and twenty years are short compared to the 1,000 years that have passed.

Before Yang Yi returned, the central defense line guarded by the Yu family was broken by the Kunyang Clan and the Beast Clan legions.

Because it has the backing of a strong military industry, controls the federal authorities, and has the most abundant resources of the human federation, the Yu family has been responsible for guarding the key defense line for more than two hundred years. Although this violates the ancestral teachings of the Yu family, that is, the founder of the Yu family, Yu Tingxuan, left a testament prohibiting future generations from joining the army and politics, but at the critical juncture of life and death, the Yu family can only stand up. The first to violate the ancestral precepts was Yu Linglong, that is, after Yang Yi left, Yu Linglong briefly served as the head of the federal state and rebuilt the federal authorities. After Yu Linglong, the Jade family has had outstanding military strategists and politicians in all generations, and it was they who propped up the crumbling human federation.

By the time of Yu Minghui's generation, the Yu family already had the most powerful military force in the Human Federation.

It is precisely because of this that the Yu family has the unshirkable responsibility to undertake the defense task in the key direction.

It's a pity that even if the Yu family goes all out, the children of the Yu family will not be able to support each other, at most it will only slow down the enemy's advance.

With the fall of the Central Line once again, the enemy is not far from their home system.

In fact, this is already the fourth central line of defense.

More importantly, after the corps on the central line of defense were forced to retreat, the corps on the other lines of defense also had to retreat, otherwise the flanks would be threatened. What's more, those marshals and generalissimos guarding other directions first thought about preserving their own strength, and they would not risk their own legions at all, so as long as there was a problem with the central defense line guarded by the Yu family, they would retreat to the reserve defense line at the first time.

In fact, the enemy has long seen this.

According to the information provided by Yu Mingzhen, in the past hundred years, especially after the Yu family became the most powerful force in the Human Federation, the enemy has focused on the central defense line, and each time he will put heavy troops in the central direction, and only feint in other directions. As a result, the Yu family endured most of the pressure, and even determined the direction of the entire battlefield situation. Although Yu Minghui and Yu Mingzhen thought of many ways to mobilize the legions in other directions and reduce the pressure they were under, they had little effect. As a result, when the Yu family went all out, and even had to use their own children to supplement the grassroots troops, they were still unable to hold the existing defense line.

For more than a hundred years, the Jade family has been holding on, and all they have gained is to make the enemy spend more time and move forward at a greater cost.

That is, after the fall of the central defensive line, the legions on all fronts retreated in great strides for hundreds of light years.

After this retreat, the area of control of the Human Federation has shrunk by almost a third, and the number of star systems still controlled by the Human Federation has been reduced to 100,000. If you get rid of the star systems near the battle line, there are less than 80,000 left that can be exploited by the Human Federation. Among the fallen star systems, there are some irreplaceable values, such as the production of strategic resources. Affected by this, the strength of the Yu family was greatly reduced. According to the report submitted by Yu Mingzhen, the output of the military industry alone has been reduced by three percent due to the fall of these star systems. Before Yang Yi returned, federal authorities were debating whether to lower rationing standards again, as several of the fallen star systems were major food producers. Although it only reduced production by about 10%, the impact on the already extremely tight grain was still very large. If the ration standard is not lowered, it will be filled with a strategic reserve, which will last for up to five years. It is clear that no one expects to regain a fallen galaxy within five years, and not a single galaxy has been regained in more than a hundred years.

To put it simply, the Human Federation has been compressed into a corner of the North Fourth District.

Of course, this is not the biggest threat.

The real threat is that the vanguard of the enemy has reached less than five hundred light-years from its home system.

What kind of concept is this?

Even a normal cargo ship can travel five hundred light-years away with a single space jump. If it weren't for the fact that the Jade family had set up a reserve defense line in advance, cleared the space jump nodes on the original route, and set up a lot of traps, I am afraid that the enemy would have hit the home galaxy.

The problem is that this depth is simply not reliable.

In Yu Mingzhen's words, as long as the enemy is well prepared and has enough reserves, then after the next attack, that is, after breaking through the defense line of the human legion again, he can continue to advance towards the home system. Because it was impossible to form more legions to guard the reserve line, even if the Yu family was prepared, it would not be possible to gain a firm foothold on the reserve line as before, and even unable to complete the deployment of the reserve line in time. In other words, when the enemy attacks again, the home system will be attacked. Because the other Commissioners' districts are not tied to the home system, they may not be able to send legions to defend the home system.

In fact, before Yang Yi returned, the main work that Yu Mingzhen did was to improve the defense deployment of the home galaxy.

Of course, Yu Mingzhen did not forget to take advantage of all the conditions that could be used.

That is, try to steer the enemy in other directions, so that the enemy thinks that before attacking the home system, he must first conquer other areas controlled by the Human Federation.

To this end, Yu Mingzhen proposed to the federal authorities to begin preparing for a strategic shift, i.e., abandoning the home system if necessary, so that vital military factories would first be moved elsewhere and regulations on other theaters should be relaxed. To put it simply, it is to allow each commissioner to recruit more soldiers in their own theater to form more legions, and to help these commissioners arm the newly formed legions by providing military productivity, so that each theater has the ability to resist on its own. Only in this way can the Human Federation continue to resist after the fall of the home system, and only then can it hope to retake the home system one day in the future.

Of course, the consequences of this are also devastating.

To put it simply, making the war zone under the control of the various commissioners become a de facto independent kingdom will inevitably lead to the division of the human federation in the end. More importantly, after the loss of unified coordination and command, no defense zone was able to withstand the enemy's attack. It may take more time for the enemy to destroy the Human Federation, but as long as this step is taken, the defeat of the Human Federation will be a foregone conclusion.

It was precisely because of this that the federal authorities did not approve Yu Mingzhen's proposal, or rather discuss it.

In fact, even Yu Minghui did not approve of this. Although he knew that Yu Mingzhen's intention was to divert the enemy, reduce the threat to the home system, and gain more time to strengthen the defense of the central defense line and the home system, so as to have a greater certainty of defending the home system, he also knew that as long as he took this step, he would not be able to turn back, and Yu Mingzhen and the Yu family would become sinners of human civilization because of this.

It can be said that this should not be done unless absolutely necessary.

Fortunately, Yang Yi's return changed all this.

It's just that in front of Yang Yi is a huge mess. Although Yang Yi's strength is superior, and the army of soldiers armed by him can sweep everything, it is definitely not an easy task to clean up this mess, and at least it takes enough energy and time to invest.

At this point, the area controlled by the Human Federation was only a quarter of the Northern Fourth District. If you take the number of star systems as standard, it is less than one thousandth of the Southern Alpha system. If measured by the size of the star system, to be precise, the standard of resources and environment, it is not even 1/10,000th of the Southern Alpha system. In this narrow area, ten trillion humans are crowded, and about a trillion inhabitants of other civilizations who have taken refuge in the Federation of Humans. Even if there is no threat from the enemy, it is a big trouble to just meet the survival needs of so many people. It can even be said that the enemy does not need to continue to attack at all, only needs to blockade this area, and the Human Federation will be defeated due to the depletion of resources. Of course, with the military strength of the Human Federation greatly weakened, it is more cost-effective to continue the offensive than to impose a total blockade.

After having a comprehensive understanding of the battle situation, Yang Yi also sighed.

He did come back late, but not too late, at least in time to get back to the Southern Alpha system. If we delay in the black hole for a few more decades, I am afraid that the human federation will no longer exist.

Subsequently, Yang Yi asked Yu Hongxing to send a group of scientists, and also asked Yu Mingzhen to prepare enough spaceships.

It was not used to transport legions, nor to transport supplies, but to transport the large Origin Energy Converter that those scientists had helped Yang Yi create.

According to Yang Yi's arrangement, these large-scale original energy converters will be sent to various star systems in batches to fundamentally solve the problem of energy supply, and with the industrial production capacity provided by the Yu family, they can basically meet the survival needs of residents everywhere and alleviate the contradiction in resources. Of course, they are all large primordial converters with the Hallows at their core, each of which can provide sufficient energy for all the planets in a star system. If needed, these large primordial energy converters can also be used as energy sources to build planetary defense systems. The premise is that it must provide supporting defensive weapons, otherwise it can only provide an energy barrier for the deployed planet.

During this period, the 100,000 officers and soldiers recruited by Yu Mingzhen returned to the Federation Star one after another.

These officers and soldiers were all incorporated into the special regiment under the direct command of Yu Hongyang, and they directly obeyed Yu Hongyang's command, but they did not adopt the original establishment, but took the ten-man squad as the basic unit. According to Yang Yi's arrangement, they will receive relevant training in the home galaxy, and only after they are fully armed, that is, the royal fighters produced by the Yu family, will they be sent out to carry out combat missions.

Fortunately, the Yu family has rebuilt the factory that produced the Imperial Fighter and trained the first batch of skilled workers, so they will soon be able to resume production. (To be continued.) )
