Because of its proximity to the Greenwich Meteorite Belt and the battle of a millennium ago, the vicinity of the fort is desolate, with the nearest star system almost a hundred light-years away. In Shen Chengwen's words, this is a "vacuum zone", and the only valuable existence is this fortress that has been abandoned for thousands of years. If the legion is not strong enough, it will be difficult to capture the nearby star system even if it captures the fortress.

Launching an attack across a hundred light years is never an easy task.

Although long-distance navigation is no longer a problem after mastering the techniques of Origin Energy and Space Jumping, distance is still the biggest obstacle in the vast universe. Whether it is the Silicon Charm Alliance or the Galactic Alliance, when conducting military operations, distance will be considered first. It can even be said that both sides make their battle plans based on the separation distance of the star system, that is, the shortest distance to launch an attack.

If it's just a battleship, it's not difficult to fly a hundred light years.

The problem is that it is not an easy task to send a huge army of hundreds, thousands, or even tens of thousands of legions to fight a hundred light-years away. Not only does it take a lot of resources to send the corps, but it is even more cumbersome to send equipment and supplies to the front line. The point is, a hundred light-years is definitely not close, and it would take a full 1,000 years for a spacecraft to travel at one-tenth of the speed of light in ordinary ways. The only way to do this is to make space jumps, and it is not easy to establish and protect a route in wartime. In fact, in the past few wars, both warring sides have spared no effort to disrupt each other's shipping routes.

From a military point of view, the attacking side has to find ways to shorten the distance of each attack, preferably within fifty light years. If it exceeds 100 light years, even if the attacker has an absolute superiority in troops, it may not be able to ensure that the rear route is unimpeded. For the defenders. The ideal defensive tactic is to widen the depth and distance between the defensive lines, so that the attacker has to attack from a greater distance. In fact, this is also a true portrayal of the past Greenwich Wars, and it is also the key to the passive situation of the Galactic Alliance, that is, the northern region of the Southern Alpha system. In other words, in the area adjacent to the Greenwich Meteorite Belt, the density of star systems is greater and the separation distance is shorter, making it difficult to strengthen defenses by expanding the depth. The Silicon Charm Alliance was able to invade the Southern Alpha Galaxy in several wars and kill the hinterland of the Southern Alpha Galaxy, which is actually related to the greater density of star systems in the Southern Alpha Galaxy. To put it simply, the South Alpha Galaxy is slightly smaller in size and has nearly 30% more star systems than the North Alpha System, so the South Alpha Galaxy has a greater density of star systems. Star systems are separated by shorter distances.

In fact, thousands of years ago, after the Second Greenwich War, several civilizations proposed to destroy some star systems in the Northern Region and expand the distance between star systems, so as to strengthen the defense strength of the Northern Region and deal with the threat from the Silicon Alliance.

Although objectively speaking. This is indeed an effective approach, but it is simply not possible. Because the basic pattern of the Galactic Alliance has been formed, the Northern Region is home to thousands of civilizations, including the Human Federation, while other civilizations are obviously reluctant to accept refugees from the Northern Region. Because thousands of civilizations are involved, and these weak civilizations are inextricably linked to the top civilizations, the matter is finally closed.

Obviously, in the Silicon Charm Alliance. There is no such problem at all.

If the Galactic Alliance's coalition hadn't invaded the Northern Alpha system more than a thousand years ago, the vicinity of the fortress would not have been so empty.

At that time, the Silicon Charm Alliance collapsed on all fronts, not to mention blocking the coalition forces of the Galactic Alliance from the Northern Alpha Galaxy, and whether it could hold the mainland was a question. When the human legion acting as the vanguard of the rush into the Greenwich meteorite belt. The Emperor of the Silicon Alliance realized that there was no way to keep the human legion out of the North Alpha Galaxy, and the native star system would soon be attacked, and if he failed to gain a foothold in the native land and let the human legion go deep into the hinterland of the North Alpha Galaxy, the consequences would be unimaginable. It's a pity that the Greenwich meteorite belt has nowhere to defend, and the human legion is advancing too fast to readjust the deployment of troops. As a result, the Emperor of War personally constructed the planetary fortress, and at the same time adopted the defensive tactic of fortifying the wall, that is, destroying all star systems within a hundred light years of the fortress, leaving the human legion with no choice but to storm the fortress. Although this decision destroyed hundreds of star systems and killed countless silicon-based creatures in these star systems, the effect was ideal, and the human legion was unable to invest enough troops because it had no foothold, so it was unable to lay the fortress in time. After the devastating destruction of the fortress, the Human Legion lost the basis to continue its offensive and was unable to make it to the heart of the Northern Alpha System. It can be said that if the Emperor of War had not destroyed the star system near the fortress and given the human legion a foothold to continue advancing, even if the fortress was devastated, the Fifth Greenwich War would not have ended immediately, and would have lasted for a long time.

Of course, more than a thousand years later, the situation in this region has changed dramatically.

After the end of the Fifth Greenwich War, the vicinity of the fortress was littered with small black holes and energy black holes, the remnants of destroyed star systems. Although Kutum did not plan to repair the fortress after he took over, after all, a lone fortress was of little value, but when building the Greenwich Line, Kutum still cleared the obstacles near the fortress, that is, those black holes.

Mainly, the fortress is in the center of the entire defensive line, and those black holes have an effect on the routes that pass through the vicinity.

Obviously, when cleaning up the black hole, Kutum certainly did not expect that the human legion would cross the Greenwich meteorite belt again and enter the North Alpha system.

This can't be blamed on Kutum, because Kutum doesn't know that the Emperor of War has long since disappeared.

Perhaps for the past thousand years, the top war kings, including Kutum, have been preparing for war, and they are all dreaming of a disgrace.

In order to launch an attack, it is natural to clear the obstacles in the offensive line.

And that's exactly what happened.

About thirty percent of the Silicon Charm army that invaded the North Fourth Sector, especially the Silicon Charm army commanded by Kutum, used the route passing through here to enter the Greenwich Meteorite Belt and then reach the North Fourth Sector. In addition, during the retreat, many legions also returned to the Northern Alpha system.

Only now, it is Yang Yi's turn to take advantage of this favorable factor.

Of course, it is only relative to say that it is advantageous, that is, there is no threatening black hole nearby, and the unfavorable factor also exists, that is, it is too far away.

Not to mention the main force of the Galactic Alliance, even if it is a human expeditionary force, it may not be able to successfully reach the star system a hundred light-years away. With limited troops, it is obviously more difficult to ensure the safety of this 100-light-year-long logistics supply line.

Fortunately, Yang Yi did not plan to take the expeditionary force on an adventure, and there was no need for this.

For him, it would not be a problem to reach a galaxy a hundred light-years away by jumping through space.

Don't forget, Yang Yi has an emperor-level fighter, Lin Feng also has one, and there is also a small point that can control space, as well as the twelfth-level Canglong.

To be on the safe side, Yang Yi and Lin Feng took the lead, the soldiers led by Shen Chengwen followed, and Barnes stayed in the fortress. Yang Yi asked Barnes to help, only hoping that Barnes would stay behind to guard the fortress and deal with possible attacks. According to Yang Yi's judgment, after they marched into the nearby star system and achieved victory, not to mention the top war kings, even those who were not very strong would be moved. If the top Warlord sends troops again, he will definitely attack the fortress, as this is the best tactic to force back the human expeditionary force. As long as the fortress is laid, because the rear is unstable, the human expeditionary force can only give up the occupied star system.

This is a very simple truth, of course Barnes knows the power involved, so after Yang Yi brought it up, he immediately agreed, and patted his chest to promise that as long as he is alive, he will not let the fortress fall into the hands of the enemy, so that Yang Yi can rest assured that he will boldly attack the enemy's star system.

Actually, Yang Yi just didn't want Barnes to be there.

It's very simple, it was Yang Yi who attacked the star system, but it was not Yang Yi who occupied and controlled the star system next, but Kuria, who had already received the order.

In any case, Yang Yi is a human being, not a silicon-based creature.

Even if Yang Yi tamed a twelfth-level blue dragon, and it was Lombardo's blue dragon, it would not be able to change his identity, let alone let him be recognized by silicon-based creatures.

What Yang Yi has to do is to use this time to help Curia unify the entire jurisdiction and eradicate the obstacles that prevent Kuria from becoming a top war king. According to Yang Yi, only when Kuria develops and grows, can they gain a firm foothold in the North Alpha System and advance to the hinterland of the North Alpha System. As for whether Kuria is reliable or not, it is not a problem at all in Yang Yi's opinion, because he has once again proved his strength. As long as Kuria was not very stupid, he would not have defeated two top-level war kings and tamed a twelve-level wild dragon that was once the battle emperor's car and later owned by Lombardo. Besides, Kuria has always actively cooperated, and he is even more obedient to Yang Yi.

Because Barnes didn't follow, and the large army led by Shen Chengwen was still behind, Yang Yi was not in a hurry, and he didn't need to be in a hurry. The point is that Curia also needs some time to mobilize the Silicon Charm Army, so Yang Yi has to slow down so that he can arrive in time.

"Thorne Galaxy" is Yang Yi's first stop, and it is also the beginning of a new journey.

In the lingua franca of the Silicon Alliance, "Thorne" means "land of the dead" / This star system is indeed a land of death, at least for silicon-based life. Just from another perspective, the Thorne system can be said to be the most ideal foothold for the human expeditionary force. (To be continued.) )
