The one who assassinated Yu Qingyu was a federal soldier from a colonial planet. During Yu Qingyu's promotion ceremony, he shot Yu Qingyu in the head and was killed by other guards. Although Yu Qingyu was taken to the emergency center immediately after being shot, his brain was severely damaged and was necrotic before receiving help. After several days of rescue, the hospital gave up the treatment with the consent of Yu Qingyu's wife.
However, this matter is obviously not that simple.
Although according to later investigations, the officer who assassinated Yu Qingyu came from a colonized planet, and the star system where the planet was located happened to be in the "isolation zone" and was destroyed during the third full-scale battle. It was Yu Qingyu who gave the order. , That is to say, there are reasons to believe that the officer's assassination of Yu Qingyu was a personal vengeance, that is, revenge for the relatives who lost their lives. But as Yu Qingyu's guard, he obviously wouldn't come from a colonized planet. In the relevant records of the military department, the officer joined the army in the homeland galaxy and received five years of higher education in the military academy. Otherwise, it would not be possible to become Yu Qingyu's guard. In addition, in the assassination incident, Yu Qingyu's other guards did not subdue the assassin, but directly killed the assassin. There was also a big problem. At least in the circumstances at the time, the other guards should arrest the assassin.
Of course, these are just speculations, and there is no evidence that Yu Qingyu's death is related to the military department.
However, there are sufficient reasons to believe that Yu Qingyu's assassination was not accidental, and it must have a lot to do with vested interest groups at the time. Quite simply, after being promoted to marshal and gaining absolute dominance, Yu Qingyu will become the absolute master of the human federation, and will inevitably pose a threat to vested interest groups. Even under the command of Yu Qingyu, the human federation won the final victory, those vested interest groups would not be able to get much benefit from it. Only by eradicating Yu Qingyu can we ensure that these vested interest groups continue to rule the human federation, and can also ensure that they will be the final winner of this war. Obviously, they can't tolerate Yu Qingyu's existence.
What happened next is the best proof.
Soon after, the federal authorities posthumously awarded Yu Qingyu as the Generalissimo, but it was just a false title and had no practical meaning. Immediately afterwards, the federal authorities cultivated the wartime bill and imposed strict restrictions on the scope of power of the marshal and the general, which greatly weakened the power of the marshal and the general. According to the revised regulations, Marshals and General Marshals are only regional commanders, and they only have absolute control in their jurisdictions. They are still subject to the command of the military department and comply with federal laws. They have no right to surpass the federal authorities under any circumstances. Even within the military, the powers of the marshals and generals are restricted by the military headquarters, that is, actions can only be taken under the authorization of the military headquarters.
Obviously, through this method, the federal authorities and the military have consolidated their positions.
However, no one denied Yu Qingyu's tactics, and no one proposed new defensive methods.
After Yu Qingyu was assassinated, several marshals were entrusted by the federal authorities and the military, and the lines of defense were divided according to the deployment areas of these marshals' original troops.
It is a pity that the impact of Yu Qingyu's death does not stop there.
At the same time when the Human Federation adjusted its defenses, the four second-rate top civilizations launched the fourth round of offensive, and the fourth full-scale battle began.
In fact, this was the shortest full-scale battle during the entire war, but its impact was the most far-reaching. It can even be said that this battle has completely changed the situation on the battlefield, and the Human Federation has therefore lost the initiative and has never been able to reverse the situation.
In this full-scale battle that lasted less than five years, the Human Federation lost all the frontier strongholds established by Yu Qingyu.
It can be said that if the four second-rate top civilizations still have enough forces to continue to advance to the homeland galaxy after capturing these strongholds, the human confederation would have been destroyed more than four hundred years ago. However, judging from the situation at the time, the four second-rate top civilizations did not have the ability to continue to advance.
Quite simply, the fourth full-scale battle broke out at this time, and it was closely related to Yu Qingyu's assassination.
Judging from the situation at the time, the four second-rate top civilizations did not expect Yu Qingyu to be assassinated, and did not make any preparations for Yu Qingyu's assassination. According to the deployment of the forces of the four second-rate top civilizations after the third full-scale battle, the fourth full-scale battle will not start until 20 years at the earliest. After all, launching a full-scale offensive requires sufficient forces and a lot of time. Make preliminary preparations. In addition, as long as Yu Qingyu is alive, the four second-rate top civilizations can't expect to be able to defeat the human confederation in one battle, let alone annihilate the human confederation. In fact, just Yu Qingyu's deterrent power is enough to stop the four second-rate top civilizations.
In fact, this was also the key reason why Yu Qingyu took the initiative to end the third full-scale battle.
The four second-rate top civilizations need time to prepare for the next full-scale attack, and the Human Federation also needs time to prepare for the next full-scale battle. If there are twenty years, the Human Federation will be able to build the forefront strongholds established by Yu Qingyu in the third full-scale battle into a solid fortress, forming an unbreakable line of defense. As long as this line of defense is there, the four second-rate top civilizations will not be able to penetrate the Beisi District. According to Yu Qingyu's vision, a few more full-scale battles and four second-rate top civilizations will pay a huge price to force the enemy to sit at the negotiating table and discuss the truce with the Human Federation, thus ending the war.
In fact, this is exactly the hope that Yu Qingyu brings to the human federation.
Unfortunately, Yu Qingyu was assassinated and died, which changed everything.
In the eyes of the four second-rate top civilizations, after Yu Qingyu was assassinated, the human confederation lost its only commander, and it was a good time to attack the human confederation in one fell swoop. Although there are problems of one kind or another, as long as you seize this opportunity, you can always get some gains.
Of course, the result is indeed the case.
After the four second-rate top civilizations launched the fourth round of full-scale offensive ahead of schedule, the human confederation is once again facing threats and will unite again to unite with the outside world. However, without Yu Qingyu's human legion, it is obvious that it would not be able to unite against powerful enemies like Yu Qingyu was alive. The point is that before that, in order to prevent the generals stationed in foreign countries from unauthorized, the federal authorities and the military have divided the entire front into several sections, and appointed several marshals to be responsible for their respective defense zones. The line of defense is cut away. Even if the talents of these marshals are not too bad, and their subordinates are fine soldiers and strong generals, there must be contradictions between them, and it is difficult to coordinately fight the enemy. The result is that no marshal can defend his line of defense because they are in separate formations.
It can be said that at that time the federal authorities and the military department ignored a crucial issue.
That is, what Yu Qingyu proposed was not only the tactics of fortifying the walls and clearing the country, but also uniting the human army into a complete group. It is also true that the human army under the command of Yu Qingyu can win more with less and win every decisive battle. Quite simply, the human legion under the command of Yu Qingyu can avoid the heavyweights and meticulously execute the battle plan drawn up by him. This is also the case to be able to concentrate superior forces on the local battlefield, thereby defeating enemies that are stronger than oneself. After losing the unified command, it also lost tactical flexibility. The legions commanded by various marshals obviously cannot abandon other strongholds for a certain battlefield, let alone abandon their own defense lines for a certain marshal's defense line, and it is difficult to invest superior forces on the key battlefield.
To put it bluntly, the divided human legion will only be broken by the enemy.
In fact, this is also an opportunity seen by the four second-rate top civilizations.
In the next five years, four second-rate top civilizations, especially the Kunyang clan and the mad beast clan, took full advantage of this once-in-a-lifetime opportunity to break through the strongholds set up by Yu Qingyu one by one. Although the Human Legion did not give up and the Human Federation did not lose hope, the Human Legion has been exhausted for five years, and has lost all key battles after paying a very heavy price.
By the end of the fourth full-scale battle, the line of defense established by Yu Qingyu had disappeared.
Of course, the courageous resistance of the human legions on various battlefields is not without results, and the biggest result is that the enemy's forces are consumed on a large scale, making the enemy unable to continue to advance to the home galaxy, and has to temporarily stop the attack after it has captured the defense line.
At this point, the first stage of this war, that is, the early stage, has ended here.
In the four full-scale offensives, that is, the four full-scale battles, both sides suffered extremely heavy losses, and the forces mobilized before the war were almost exhausted. Although the human confederation is dying, the four second-rate top civilizations cannot eliminate the human confederation in one fell swoop. For the warring parties, the next thing to do is the same, that is, to expand the scale of mobilization and prepare for the subsequent decisive battle.
Although the two sides did not sign an armistice treaty, neither side launched a large-scale offensive for the next fifty years.
Quite simply, both sides need time to rest and regroup their forces.
Fortunately, the Human Federation has made no more mistakes. Although the line of defense was lost, Yu Qingyu's insisted tactics were recognized and accepted by more people. In the next two decades, the Human Federation gave up nearly 10,000 star systems and built a new line of defense. Although affected by the reduction in overall strength, the mobilized forces of the Human Federation are far less than before, but as the defense line is greatly shortened, the required forces are also greatly reduced. As long as you stick to the defensive tactics of solid walls and clear fields, you can stick to it even if you can't completely defeat the enemy. In any case, after paying such a high price, the Human Federation at least knew that it had found the right direction.
But how long can it last
At the end of the fourth full-scale battle, no one knew how long the human confederation could last, and not many people even believed that the human confederation could withstand the enemy's fifth full-scale attack. Quite simply, it was only three of the four second-rate top civilizations that suffered huge losses, and the Extreme Clan never sent troops to participate in frontline battles. If the Extreme Realm Race exerts its strength at this time, then the Human Federation will not be far from extinction.
