The second layer is advancing more slowly, and it is clear that the Empire has placed a considerable number of troops in the laboratory on the second layer for defense. The speed of advancement has slowed down again compared to before. But more importantly, while the second layer was slowly advancing, Behemoth, who was in charge of the defense of the asteroid belt, reported to Yang Yi through the command network that the Imperial fleet had jumped in and that the swarm was engaged with the Imperial fleet.

Behemoth's defeat was only a matter of time, and according to Behemoth's report, at least three battlecruiser formations had arrived in the Imperial fleet, and Behemoth alone simply could not afford to delay for too long. The Pride of Ortaris chose to retreat as soon as the Imperial fleet jumped in, away from the war zone. Fortunately, the hop network itself is not affected by distance, and they can still get troops and supplies through the hop network provided by the Crystal Tower.

Therefore, when time was gradually pressing, Yang Yi asked the assault troops to speed up their pace. Now that the goal was halfway there, they just had to rush to the very core of the lab where the hybrids were being held. Black Rose quickly changed her plan, leading her troops to rush to the junction between the second floor and the core layer directly according to the schematic diagram, and then quickly asked Shantila and the Star Spirit troops to go down to clear the field, and she led her troops to the core layer close behind.

While Behemoth was engaged in a fierce battle, the assault team reached the core in a hail of bullets. Presumably knowing that the Imperial fleet had arrived outside the asteroid belt, the laboratory garrison became more and more resolute in its defenses. It is unclear how many Imperial soldiers are still alive, at least since the breakthrough of the lab, at least nearly two dozen Imperial soldiers have been definitively determined to have died in the raid. On Yang Yi's side, dozens of soldiers were also killed, including two squads who were directly beaten until they lost their combat effectiveness, withdrew from the battle and were sent back to the ship.

According to the information provided by A1, the latest information in her database indicates that the laboratory in the Kastana system has a garrison of nearly 100 people. But it has been a long time since she served Yang Yi, and no one knows what the garrison of the laboratory is doing now, and Renault has not given any detailed information, so they can only charge forward head-on.

As a result, they were hit hard by the Imperial garrison at the first line of defense, and in a large hangar they were attacked by heavy fire from the Imperial garrison, including large-caliber machine guns, anti-armor weapons, and large armed robots, and they were even hit by the artillery of a siege tank. A squad of 7 people who stormed the hangar was blasted back into the corridor and survived, but was blown up to the point of intracranial hemorrhage, and was finally sentenced to death and buried at sea after the operation.

Black Rose was also unable to break into the hangar. Her physical body was not enough for her to carry the piercing guns, large-caliber machine guns, and anti-armor weapons of siege tanks. She couldn't channel herself through the walls in any way. In desperation, she had to ask the Star Spirit troops to come in to support.

At first, Black Rose intended to put fanatics on the field, and it played a role. The short-lived psionic form formed by the three Zealots during the charge did indeed allow them to dodge the heavy fire. However, due to their lack of combat capabilities, the wide terrain in the hangar, and the open Imperial garrison, the three zealots were able to take out only one armed robot before they could be rushed back to the Pride of Otaris.

As a last resort, Black Rose can only choose to believe in the dragon knight's combat ability. As an astral unit active on the battlefield during the War of the Brood, the Dragon Knights possessed heavy armor and shields, but due to their large size and unsuitable for fighting in a cramped indoor environment such as a laboratory, they were only assigned one for backup. I didn't expect them to actually use this dragon knight.

However, because the door was too small, they had to have the Reaper blow up a large enough gap with the Deuterium-4 bomb, and then the Dragon Knight rushed straight into the hangar before the enemy could react, and a group of Marines and Zealots immediately rushed in behind him to disperse.

The toll was high, but they had to use it if they wanted to move quickly. As a result, nearly three squads, including a four-man raider squad for support, were completely incapacitated, allowing Shantila to enter the arena and directly use Psionic Storm to destroy and shred the threatening siege tank. At this point, an entire squadron of human troops completely lost their combat effectiveness and withdrew directly.

With so many casualties, Black Rose had to rethink its offensive strategy. However, Yang Yi's urging from inside the bridge became more and more urgent, and the casualties that Behemoth could afford to suffer became less and less, and they had to reach the hybrid detention area as soon as possible. So Black Rose had no choice but to regroup the team again. Unable to obtain an effective supply of men and equipment, Black Rose had to rely on her and Shantila's psionic powers as the main assault force.

But their psionic powers, though powerful, are not invincible. The previous battle for the capture of the hangar is proof enough. Even if Shanti were to rush in with her shield drawn, she wouldn't be able to destroy enough enemies before she was teleported back to the Pride of Ortaris. Besides, she couldn't be urgently teleported away at this time because of serious injuries. And Black Rose's psionic power is far inferior to Shantila's, and it is impossible to make an effective assault, so it can only be filled with human lives.

In the close-quarters battles that followed, in the corridors and rooms, they encountered fierce resistance like never before, and Imperial soldiers, researchers, and even cleaners all took up arms to resist the advance of the commandos. Although most of the resistance was quickly broken down, this greatly slowed down the assault team's attack.

Finally, just as they were about to arrive at the hybrid laboratory, Yang Yi issued a retreat order on the bridge.

"What?! Head, we're going to be in the detention area soon! The first time Black Rose heard the news was extremely shocked and furious, "Give us a little more time, and we will be able to evacuate in no time!" ”

"We don't have time, the swarm of Behemoth can't stand it anymore, and if we continue to fight, all of you will be planted in the laboratory. Obey the order, I give you a quarter of an hour, immediately withdraw to the crystal tower within the range of the network, and quickly evacuate back to the ship. Yang Yi's voice was also helpless, "The sooner the better, time is precious." ”

Behemoth's voice also resounded in the command network: "Everyone, please hurry, my swarm will not be able to hold up for long. ”

Hearing this, Black Rose glanced at Shantila beside her, and Shantila just nodded to her, and then turned around and went back the way she came, ready to leave the lab.

Black Rose glanced at the direction of the detention area, stomped her feet angrily, and finally ran out of a magazine in one breath in the direction of the detention area, and finally said to the communication channel of the whole team: "Black Rose called all units, the mission failed, immediately retreat to the K3 evacuation point, I repeat, immediately retreat to the K3 evacuation point." We will have a mass evacuation in fifteen minutes. Complete. ”

(I saw that some readers thought Valkyrie was too small, and I couldn't solve this kind of thing, because it was Blizzard's own setting.) Here, I also ask all readers to give comments and try to mention the problems that I can correct. Of course, if it's a complaint about Blizzard or the content of this article, it's no problem, such as Blizzard Pegasus, author NC, etc., but if you want to seriously put forward comments and feel that there is a problem, try to mention the problem that I can modify. For example, the Valkyrie-class frigate is too short, and it takes two or three hundred meters to be enough, I can't modify it. The setting of the Valkyrie-class frigate was given by Blizzard, and I remember that there seems to be a kind of translation that is a Wagley fighter? It's the equivalent of asking me why the Arden Spear is 76 kilometers long, which I really don't know...... ）

(Also, I need to remind that frigates are not the kind of large warships of the three or four hundred class.) The earliest frigates were three-masted armed warships in the 16th century, with a displacement of only about 240 tons ~ 400 tons. The first special frigates in the world were a group of special frigates built by Russia after the Russo-Japanese War, with a small displacement (400-600 tons), weak firepower, poor wind and wave resistance, and were only suitable for offshore activities. ）

(I take our country's hull as an example, the Type 054A ocean-going frigate (full load displacement of 4000 tons) is 154 meters long and 16 meters wide; And the smaller Type 056 frigate is even only 89 meters long and about 12 meters wide. The Type 052D destroyer is 157 meters long and 19 meters wide; The name of the Type 055 missile destroyer should also be considered a household name, as a 10,000-ton drive, the length of the ship is estimated to be about 187 meters. And this is already a destroyer, there is a destroyer in the history of the Koplu Star Sector, and there are even light cruisers, but destroyers can only sail within the galaxy, and light cruisers are now mostly used as cargo ships, please go to the interstellar history bar for details. A Valkyrie-class frigate like UED is even less likely to be as big as three or four hundred meters. ）

(Moreover, the Old Federation's Behemoth-class battlecruisers were only 500 meters, and Hyperion was about this size, the Busefalos, which Blizzard had given clear data, was only 550 meters, and the early prototype Leviathan-class battlecruisers were estimated to be shorter, perhaps only three or four hundred meters.) If the missile frigate of the UED is three or four hundred meters, it will be almost the same size as the battle cruiser. It can probably be compared to the current missile frigates that are about the same size as aircraft carriers. This is clearly impossible. ）

(One thing to understand is what exactly the corvette is for.) UED's Valkyrie-class frigates are clearly intended to be used as ship-based anti-aircraft missile launch platforms, and nothing else. The HALO missile itself is a cluster launch against a large number of dense air units. As long as this purpose is achieved, even the Valkyrie-class frigate will be used to the fullest. According to such a line of thinking, it is completely unnecessary to build a hull of three or four hundred meters. If that doesn't make you feel relieved, you can simply think of it as a Wagley fighter. ）

(As for why he called a frigate, first, it was set by Blizzard, and secondly, basically in the universe, Valkyrie's missiles were enough to deal with ordinary pirates, and if it was against a regular army, it was not something that one or several Valkyries could deal with.) ）

(Actually, I originally wanted to post it yesterday, because to be honest, I was actually quite angry at first, and it was too sloppy for Blizzard to put something on my head.) But then I thought that it might be suggested by readers who don't play games and just watch science fiction, and I almost understood it. So I thought about sending it out quickly, but ...... I touched it yesterday, ahem...... ）
