"The demons have attacked, prepare for war!" Just after getting acquainted with the Rock Fortress, Excellence received a warning of war, and the demons changed their previous attack habits and launched an attack in advance.

Upon receiving the alert, Excellence immediately gave the order: "Everyone is immediately behold!"

At the same time, he also returned to his immortal ship, and then drove the immortal ship directly into the top of the Rock Fortress, fusing the immortal ship with the Rock Fortress.

This is a special combat form of the Rock Fortress, which directly turns the immortal ship into a part of the fortress, and then makes the immortal ship replace the original control center of the fortress and become the control center of the rock fortress.

Doing so will not only allow the best to grasp the power of the fortress as quickly as possible, but also effectively strengthen the power of the fortress, after all, the Xuanxian-level immortal ship, even if it has not completed the upgrade, its failure should not be underestimated.

Of course, it is not only excellent that can do this, but other warships can also be integrated into the fortress's defense system in this way, and behind the Rock Fortress, there are countless battleship embedding points.

Whether it's a battleship piloted by a warrior or an empty battleship, they can become part of the Rock Fortress through these embedded openings, adding power to the Rock Fortress.

Even if a normal warship is not good at attack and defense, it can add a power source to the Rock Fortress.

The eternal furnace of the Rock Fortress can provide unlimited energy, but unlimited energy does not mean that it can be output infinitely, and the power of energy output is always limited, which is the key to restricting the play of the fortress.

The embedded port at the back of the fortress is the key to solving this problem, which can accommodate ten fleets, and can bring more than 100,000 energy sources to the fortress, ensuring that the defense of the fortress is on a higher level.

Ten fleets remained in the Rock Fortress, and the other 20 or so fleets entered the defense system attached to the Rock Fortress, and the three defense systems with the fortress as the core, together with more auxiliary facilities, constituted the defense system of the entire 78th Theater.

In the foremost of them were not three fortresses, but a separate formation of the Shield Legion, followed by three huge fortresses, and behind them were a larger number of starry fortresses of all levels.

The Shield Legion is the outermost defensive force, and it is also the strongest link in defense, he is not only strong in defense, but also flexible in action, any demon legion wants to break through the defense line, it is impossible to bypass him, only by breaking through the Shield Legion first, can you attack the fortress in the rear!

This is also the reason why those legions with a little strength are reluctant to assist the Shield Legion, lacking the opportunity to participate in the war, and it is difficult to improve without actual combat.

It's not that the Shield Legion doesn't know about this, it's just that they can't help it, and the belief of the Shield Legion is determined that it is absolutely impossible to let any enemy break through their defenses!

Of course, Excellence doesn't care if there is a chance to play in person, the Demon Slayer Legion has just been formed, and has not participated in large-scale wars, the primary consideration is not actual combat, but adapting to the battlefield, and at the same time not having too many casualties!

Assisting the Shield Legion just met the requirements of excellence, not only had the opportunity to practice in actual combat, but also ensured safety, he couldn't ask for more!

And they are not without the opportunity to participate in the war, no matter how strong the Shield Legion is, there is only one legion, and the demon race on the opposite side has ten legions.

Relying only on the Shield Legion, it is impossible to stop all ten legions at the same time, once the demon attack is too strong, and the ten legions attack at the same time, the three fortresses will definitely be the first to go to the front and fight side by side with the Shield Legion. When the time comes, there will be a chance for the Demon Slayer Legion to exercise!

However, the Yama legion, which came relatively late, was more pitiful, because it came relatively late, so it was assigned to the rear to preside over the part of the defense facilities, and at the same time as a reserve force.

Since it is a reserve force, if it is not a very critical force, they probably have no chance to fight!

When it really came time to use the reserve force, most of the shield legions couldn't stop it, and the reserve force was basically no different from sending it to death.

Therefore, the situation of the Yama Legion is quite painful, and they want to have the opportunity to go to the battlefield in person, but they don't want that situation to really happen......

The demons quickly attacked, and at one time they invested three legions and one hundred and fifty fleets, and they slaughtered this side in a mighty way.

But soon a transparent shield wall with no edge in sight stood in front of them, and this shield wall looked like an illusory image, without that feeling of strength and heaviness, which was very different from what Excellence had seen before.

Of course, Excellence doesn't think that the actual defensive power of this shield wall will be as weak as it seems, and under its fragile appearance, there must be some kind of powerful ability hidden, and the Shield Legion will not dare to underestimate it!

In fact, the demons were also afraid of this shield wall, and the three legions did not dare to rush forward, and at the maximum attack distance, they first released a tentative attack.

The raging demon fire was ignited instantly, and then spread rapidly, covering a huge area in the center of the shield wall, which was still a regular demon fire realm, but the demon clan directly increased its power to the maximum.

"It's so strong!" saw the shield wall unharmed, and Excellence couldn't help but sigh.

Although they were far apart, they could still feel the amazing destructive power of the Demon Fire Domain, and before they became Xuan Immortals, the Demon Slaying Fleet would definitely not be able to stop the Demon Fire Domain of this level.

But this kind of intensity of the attack, but can not affect the shield wall to divide the good, the whole starry sky seems to be divided by the shield wall into two worlds, the shield wall is calm, the shield wall outside the magic fire is raging, with the shield wall wall as the boundary, as if the two worlds are distinct!

The power of the law within the shield wall is firmly controlled by the shield legion, and no matter what kind of law attack method the demon clan uses, it is impossible to cast it directly within the shield wall.

"Is it because the Shield Legion is so strong in the first place, or has it improved too much in the past few decades?" Excellence had a question in his heart, the shield wall he had seen the Shield Legion cast decades ago did not have such power!

If it weren't for the astonishing progress in the past few decades, it would have been the Shield Legion hiding in the first place, 'Think about the last big battle at the beginning, it seems that the Shield Legion has not been trying its best!'

"Rock Fortress is ready to be activated at any time!" At this time, Rock Fortress was also ready.

"What about the other two fortresses, have you been contacted?" asked Excellence.

"I've already been contacted, and the other two fortresses are ready!" Xu Lin replied.

"After ten breaths, activate the Rock Fortress defense system and notify the other two fortresses!" Excellence ordered.

This time, the Demon Slayer Fleet is no longer fighting independently, and Excellence can't take orders for granted, and any major decisions must be discussed and synchronized with the other two fortresses.

These three fortresses are the most important support of the Shield Legion, and they are also the most important second line of defense, and they must work together to ensure that the entire defense line is perfect!

Any behavior that may lead to an imbalance in the three fortresses is not allowed, and the Trinity is the strongest state!
