In the year 419 of the imperial calendar, half a year has passed since the founding of the Free Alliance, and the imaginary scene of the emperor's large-scale conquest of the rebels has not appeared.

On the contrary, the Freedom Alliance attacked the heart of the empire, the imperial capital, and for a while the entire empire fell into panic.

In the past six months, the Liberty Alliance has developed rapidly, the economy has recovered a lot, and there has been a steady stream of immigrants from all over the country, which has given the Liberty Alliance great confidence.

On the other hand, the empire has been busy suppressing armed rebellions in various places all day because of the rebellions, and not only has the economy not recovered, but it is much worse than half a year ago.

As a result, the Free Leader Alliance believes that the time has come to overthrow the empire, and as long as the imperial capital can be taken, the entire Xinghan Empire will collapse.

Lu Pengfei, the commander-in-chief of the Freedom Alliance and the supreme leader of the Freedom Alliance, finally came to the forefront, and people finally got to see this mysterious rebel.

Lu Pengfei gave a speech to the entire human world, and the video of the speech was spread all over the world.

Anyone who has watched this video of the speech has to admit that this man who led the rebels does have great incitement ability, and he is not far behind those famous speakers in human history.

Lu Pengfei called on young people to rise up against the oppression and rule of the empire, and his remarks themselves are not too new, the key is that this person knows how to use linguistic skills to devalue the empire to nothing, and the Freedom Alliance is said to be the savior of all mankind.

Although this kind of rhetoric could not coax those with rich life experience, it was extremely contagious to young people, and soon after this speech was made, a large number of young people flocked to the Freedom Alliance as if they were crazy.

After absorbing many young people, the Freedom Alliance is like a hormonal teenager, eager to challenge the former authority in order to prove that it is tomorrow and the future.

Therefore, the Free Alliance launched an attack on the imperial capital in this atmosphere, advancing to the imperial capital with nearly three full fleets.

If it was half a year ago, the Free Alliance would not have dared to attack the Imperial Capital no matter what, but since the Battle of the Lion King Galaxy, the morale of the Free Alliance Army from top to bottom has been extremely high, and it is better to wait if you don't attack at this time!

The three fleets that launched an attack on the imperial capital were the Lion Fleet led by Cai Qi, the Tiger Fleet led by Li You, and the Flying Wolf Fleet led by Deng Yuanqing, with a total strength of nearly 300,000 troops and more than 3,000 ships.

After a month of mobilization, the three fleets of the Free Alliance began to march towards the imperial capital, and after a jump, they finally reached the edge of the galaxy where the imperial capital was located.

Although the Empire's spy department had heard the rumors beforehand, the Free Confederate forces were still arriving faster than expected.

When the three fleets appeared at the edge of the galaxy, the people of the entire imperial capital were frightened and panicked, this kind of thing had not happened for many years, and the last time the imperial capital was attacked was a hundred years ago.

It was also a rebellion, a coalition of nobles attacked the imperial capital with the intention of overthrowing the emperor at that time, but it ended in failure, and the nobles also completely lost their military power and could no longer have private arms.

The reason why the capital of the Xinghan Empire is so important is not only because it is the political, economic, and cultural center of the entire empire, but also because it is also the best and richest place in all the human colonization systems.

Someone once described the imperial capital like this: Those who get the imperial capital get the empire; Those who win the empire get the galaxy.

This shows the importance of the imperial capital in the entire human world, if the imperial capital falls into the hands of the Free Alliance, even if the original two galaxies are lost, they can still be invincible and have a long-term confrontation with the entire empire.

The real name of this planet is Tianhan Star, and the star system to which it belongs is called the Unicorn Galaxy.

In the Unicorn Galaxy, there is not only one planet, Tianhan, but also six habitable planets in the entire Unicorn Galaxy, which is second to none among all the systems colonized by humans.

The population of these six planets is the sum of more than a dozen galaxies, and the economic size, technological level, and manufacturing capacity are all the crowns of the empire, as long as they occupy the unicorn galaxy, it is worth giving up all the other galaxies.

Therefore, if the Free Alliance wants to confront the empire for a long time, it must take the imperial capital no matter what. Once the imperial capital is taken, not only can it sit back and relax economically, but it will also deal a huge blow to the empire politically.

This time, the Free Alliance can be said to have done its best, and vowed not to give up until the goal was achieved, and to take the imperial capital in the pocket no matter what.

The news soon spread throughout the Empire, and all eyes were immediately on the war that would determine the fate of the Empire.

"Oh my God! I'm afraid the empire is in danger now! When Ke Rin saw this news, he couldn't help but exclaim.

Shangguanqi also had the same opinion: "If the imperial capital is captured, the Xinghan Empire may be finished, and now there are rebellions everywhere, and if the imperial capital is lost, the empire will no longer be cohesive." ”

However, Liu Yi had a completely different opinion, and even said to the two of them a little lightly: "Don't worry, this time the Free Alliance Army is kicked on the iron plate, and the emperor is not so easy to capture." ”

"How do you know?" Ke Rin said with skepticism: "This time, the Free Alliance Army has dispatched three fleets, and even if the imperial capital is well defended, it will be difficult to resist it. ”

"I think it's half to half likely." Shangguanqi said.

"You're talking nonsense, it's like you didn't say it." Ke Rin said with a wave of his hand.

Liu Yi smiled: "Don't forget, I used to study the defense system of the galaxy in the Military Academy, and I also personally participated in the defense design of the imperial capital galaxy, and I know very well how strong the defense of the imperial capital is." ”

Hearing this, Ke Rin and Shangguan Qi were both interested, and pulled Liu Yi to ask him to tell him what was going on with the defense system of the imperial capital.

Liu Yi thought for a while and said, "If you want to talk about the specifics, I'm afraid I won't be able to finish it in a few days and nights, so I'll talk about the general situation." ”

"Speak quickly, I'll listen to you." Kirin said.

"First of all, the Unicorn Galaxy, where the imperial capital is located, has six habitable planets, you should know this, right?" Liu Yi asked.

"Of course you know, you go on."

"Because there are six planets, the defense system of the imperial capital cannot only consider the Tianhan Star where the imperial capital is located, but also the entire galaxy." Liu Yi said and called up the map of the Unicorn Galaxy, then pointed to the map and said, "So when the entire defense system was designed, the entire galaxy was considered. ”

Liu Yi now drew a circle around the periphery of the galaxy and encircled the entire galaxy, and then said: "Therefore, in order to protect the safety of the entire galaxy, a total of three layers of defense circles have been designed, and this is the outermost layer. ”

"What the hell is this defensive circle?" Kirin asked.

"The so-called defense circle is a complete set of comprehensive defense structures, including space cities, space stations, defense satellites, warships, etc., in short, all kinds of things that can be defended, these are all connected together, and the whole body can be moved, and it is by no means easy to enter the galaxy by breaking through a point."

"To be specific, what kind of powerful weapons are there?" Kirin asked.

"Actually, I don't know all the details, but there are some powerful weapons that are not known to the world, such as the 'galactic airbag' is one of them." Liu Yi said.

"'Galactic airbags'? What is this? It seems like I've never heard of it. Shangguanqi asked curiously.

"The so-called 'galactic airbag' is actually a joking name, but it is actually a powerful field generator that, once opened, can cause a high-speed spacecraft to suddenly slow down, as if it had hit an airbag head-on. You also know what happens when a ship slows down suddenly, and it can destroy many ships in an instant without a single soldier. ”

"Can a galaxy of this size cover it all?" Shangguanqi was a little skeptical.

"It is impossible to completely cover, in fact, it is only partially distributed on the periphery of the galaxy, once the satellite detects an enemy attack, these powerful field generators will move to the forward route according to the position of the enemy ship, and then open the force field, waiting for the enemy ship to collide with itself."

"So powerful? I'm afraid the fleet of the Free Alliance won't even be able to enter the galaxy. Shangguanzaki sighed.

Liu Yi shook his head and said: "This is impossible, after all, the universe is too big, and this kind of 'galaxy air sac' cannot cover the periphery of the entire galaxy, at most it can only cover a part of the area." However, the greatest effect of this weapon is not to block the enemy's entry into the system, but to force the fleet to follow a pre-set route. ”

Why is that? What happens if you take a pre-set route? Shangguanzaki asked.

"You know, although the universe is extremely vast, it is not possible to sail any way. Especially after entering the star system, it is full of various dangers, so the number of safe routes is actually very limited.

With something like a galactic airbag, you can block some shipping routes, force fleets to take specific routes, and then set up ambushes on those routes. Liu Yi explained.

"I see, now I understand that this 'galaxy air bag' is actually a roadblock in the universe." Shangguanqi nodded and said.

Liu Yi said: "You are right, lead the enemy to a specific route, and then set up an ambush, so that you can kill and damage a large number of ships without a single soldier. ”

"Could it be that there are other weapons of mass destruction in the imperial capital's defense system?" Ke Rin reacted immediately.
