The assassin was a federal soldier from a colonial planet, and during Yu Qingyu's promotion ceremony, he shot Yu Qingyu in the head, and was immediately killed by other guards. www.biquge.info Although Yu Qingyu was immediately taken to the emergency center after being shot, his brain was severely damaged and he died before he could be rescued. After several days of rescue, with the consent of Yu Qingyu's wife, the hospital gave up the treatment.

It's just that this matter is obviously not so simple.

Although according to later investigations, the officer who assassinated Yu Qingyu was from a colonial planet, and the star system where the planet was located happened to be in the "isolation zone" and was destroyed during the Third All-Out War, it was Yu Qingyu who gave the order, that is, it is reasonable to believe that the officer's assassination of Yu Qingyu was a personal vendetta, that is, revenge for the loss of his loved ones. But as Yu Qingyu's guard, it is obvious that he will not come from a colonial planet. According to the relevant records of the military department, the officer joined the army in the home galaxy and received five years of higher education at the military academy, otherwise he would not have 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, which was also a big problem. At least in the circumstances, the other guards should have arrested the assassins.

Of course, these are just speculations, and there is no evidence that Yu Qingyu's death is related to the military department.

However, there is enough reason to believe that Yu Qingyu's assassination was not an accident, and it must have a lot to do with the vested interest groups at that time. Very simply, after being promoted to marshal and gaining absolute dominance, Yu Qingyu will become the absolute master of the Human Federation, which will inevitably pose a threat to vested interest groups. Even if the Human Federation won the final victory under the command of Yu Qingyu, those vested interest groups would not be able to gain much from it. Only by eradicating Yu Qingyu can we ensure that these vested interest groups continue to rule the Human Federation, and can we also ensure that they will become the final winners of this war. Obviously, they couldn't tolerate the existence of Yu Qingyu.

What happened next is the best proof of this.

Soon after, the federal authorities posthumously awarded Yu Qingyu the title of Generalissimo, but it was only a fictitious title and had no practical significance. Immediately afterwards, the federal authorities cultivated the wartime law, which severely limited the powers of the field marshal and the generalissimo, that is, greatly reduced the power of the field marshal and the generalissimo. According to the amended statutes, the marshal and the generalissimo are only regional commanders, who have absolute authority only in their jurisdictions, and still have to obey the command of the military department, and abide by the laws of the federation, and under no circumstances have the right to override the federal authorities. Even within the army, the powers of the marshal and the generalissimo were limited by the military department, that is, they could only act under the authorization of the military department.

Obviously, in this way, the federal authorities and the military ministry have consolidated their position.

It's just that at that time, no one denied the tactics adopted by Yu Qingyu, and no one proposed new means of defense.

After Yu Qingyu's assassination, the federal authorities and the military department canonized several marshals and divided the defense line according to the deployment area of the marshal's original troops.

Unfortunately, the impact of Yu Qingyu's death did not stop there.

Just as the Human Federation was adjusting its defensive line, the four second-rate top civilizations launched the fourth round of attacks, and the fourth all-out battle began.

In fact, it was the shortest full-scale battle of the entire war, but its impact was the most far-reaching. It can even be said that this battle completely changed the situation on the battlefield, and the Human Federation lost the initiative as a result, and was never able to reverse the situation.

In this all-out battle, which 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-level civilizations still had enough troops to continue to advance towards the home galaxy after capturing these strongholds, the Human Federation would have collapsed more than four hundred years ago. It's just that, judging from the situation at that time, the four second-rate top-level civilizations did not have the ability to continue to advance.

Quite simply, the outbreak of the Fourth All-Out Battle at this time was closely related to the assassination of Yu Qingyu.

Judging from the situation at that time, the four second-rate top civilizations did not expect Yu Qingyu to be assassinated, so they did not make any preparations for Yu Qingyu's assassination. According to the deployment of the forces of the four second-rate top-level civilizations after the end of the third all-out war, the fourth all-out war will not start until twenty years at the earliest, after all, launching a full-scale offensive requires the investment of sufficient troops, and it will take a lot of time to make preliminary preparations. In addition, as long as Yu Qingyu was alive, the four second-rate top-level civilizations would not dare to expect to be able to defeat the Human Federation with a single battle, let alone destroy the Human Federation. In fact, just Yu Qingyu's deterrent power was enough to make the four second-rate top-level civilizations stop.

In fact, this was also the key reason why Yu Qingyu took the initiative to end the third full-scale battle at that time.

The four second-rate top-tier civilizations need time to prepare for the next all-out attack, and the Human Federation also needs time to prepare for the next full-scale battle. If there were twenty years, the Human Federation would be able to build those forward strongholds established by Yu Qingyu in the Third All-Out Battle into a solid fortress, forming an impenetrable line of defense. As long as this line of defense is there, the four second-rate top-level civilizations will not be able to penetrate deep into the North Fourth District. According to Yu Qingyu's plan, a few more full-scale battles and a huge price to pay to the four second-rate top civilizations can force the enemy to sit down at the negotiating table and discuss a truce with the Human Federation, thus ending this war.

In fact, this is exactly the hope that Yu Qingyu brought to the Human Federation.

It's a pity that Yu Qingyu was assassinated and changed everything.

In the eyes of the four second-rate top civilizations, after Yu Qingyu's assassination, the Human Federation lost its sole commander, and it was a good time to destroy the Human Federation in one fell swoop. Although there are problems of one kind or another, as long as you seize this opportunity, you can always gain something.

Of course, this is exactly what happened.

After the four second-rate top civilizations launched the fourth round of all-out attacks ahead of schedule, the Human Federation is once again facing a threat, and it will once again unite and unite with the outside world. It's just that without Yu Qingyu's human army, it is obviously impossible to unite against strong enemies like when Yu Qingyu was alive. The key point is that before this, in order to prevent the generals stationed abroad from abusing their powers, the federal authorities and the military department had already divided the entire front into several sections, and also appointed several marshals to be in charge of their respective defense areas, which was equivalent to cutting a defense line that was originally complete and without gaps. Even if the talents of these marshals are not too bad, and their subordinates are also elite soldiers, there must be contradictions between them, and it is difficult to fight the enemy in a coordinated manner. As a result, none of the marshals were able to hold their own lines of defense, as they were in separate positions.

It can be said that at that time the federal authorities and the military department ignored a crucial issue.

This is the tactic that Yu Qingyu proposed not only to strengthen the wall and clear the wilderness, but also to unite the human legion together and become a complete group. It is precisely because of this that the human legion under the command of Yu Qingyu can win more with less, and can win in every decisive battle. Quite simply, the human legion commanded by Yu Qingyu was able to avoid the important and light, and could meticulously implement the battle plan formulated by him. It is precisely in this way that they can concentrate superior forces on local battlefields and defeat an enemy who is stronger than themselves. After the loss of unity of command, there was also a loss of tactical flexibility. Obviously, it is impossible for the corps commanded by the marshals to abandon other strongholds for a certain battlefield, let alone for the sake of a certain marshal's defense line, and it is also difficult to invest superior forces in key battlefields.

To put it bluntly, the divided human legions will only be broken by the enemy individually.

In fact, this is also an opportunity that the four second-rate top civilizations see.

In the next five years, the four second-rate top civilizations, especially the Kunyang Clan and the Beast Clan, made full use of this once-in-a-lifetime opportunity to break through the strongholds set up by Yu Qingyu one after another. Although the Human Legion did not give up, and the Human Federation did not lose hope, for five years, the Human Legion has been exhausted, losing all the key battles after paying a terrible price.

By the time the Fourth All-Out Battle was over, the defensive line established by Yu Qingyu was gone.

Of course, the heroic resistance of the human legion on various battlefields is not without results, and the biggest result is the large-scale consumption of the enemy's forces, so that the enemy can not continue to advance towards the home system, and has to temporarily stop the offensive after capturing the defensive line.

At this point, the first phase of this war, the initial stage, came to an end.

In the four all-out 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 Federation is dying, the four second-rate top civilizations cannot wipe out the Human Federation in one fell swoop. For both warring parties, the next step is to expand the mobilization and prepare for the decisive battle that follows.

Although no armistice was signed, neither side launched a major offensive for the next fifty years.

Quite simply, both sides need time to recuperate and regroup.

Thankfully, the Human Federation didn't make any more mistakes. Although he lost the defensive line, the tactics that Yu Qingyu insisted on were recognized and accepted by more people. Over the next two decades, the Human Federation abandoned nearly 10,000 star systems and built a new line of defense. Although the number of troops mobilized by the Human Federation is far less than before due to the overall reduction in strength, as the defense line has been greatly shortened, the number of troops required has also been greatly reduced. As long as you stick to the defensive tactics of the fortified wall, you can hold on even if you can't completely defeat the enemy. In any case, after paying such a big price, the Human Federation at least knows that it has found the right way forward.

Just, how long can it last?

At the end of the Fourth All-Out War, no one knew how long the Human Federation would be able to hold out, and not many people even believed that the Human Federation would be able to withstand the enemy's fifth full-scale attack. Quite simply, only three of the four second-rate top-tier civilizations suffered huge losses, and the Extreme Realm Clan never sent troops to participate in the frontline battles. If the Extreme Realm Clan exerts its strength at this time, then the Human Federation will not be far from extinction. (To be continued.) )
