Margaret's knight armor's primary long-range weapon was a rapid-fire autocannon. Compared to weapons like meltaguns or lances, it looked somewhat plain, even ancient and traditional.
After all, kinetic cannons were invented by humanity as early as the 1st millennium.
Now, more than forty millennia have passed, yet humanity still uses this ancient weapon.
But it must be admitted that the ancient method of propelling projectiles with kinetic energy generated by combustion and explosion to cause destruction is still very effective, even in an era four millennia later where all sorts of monsters roam.
Margaret simply aimed her weapon and fired a shot at the sealed tomb door, and cracks appeared on the Blackstone door.
However, as the door to a Necron Tomb, this gate was sufficiently massive, and it was difficult for a single knight armor to blast it open.
Fortunately, the bombardment was effective, proving that this stone door was not indestructible. So, Margaret contacted Manner and General Grigory in the rear, asking them to send people to install Thermo-meltdown bombs to breach the door.
Although she could forcefully blast open the door with her cannon, firstly, the ammunition carried by the knight armor was limited and not worth wasting so much; secondly, such bombardment would take a lot of time, which was not conducive to rescuing Alex and his group, who were trapped.
As for the weapons equipped by the Knight Squires? Their weapons were not meant for this purpose, and their power was much inferior; they couldn't breach the tomb door.
General Grigory quickly dispatched a squad of soldiers, carrying a large number of Thermo-meltdown bombs.
While waiting for the soldiers to set up the Thermo-meltdown bombs, Margaret noticed that they all had a special metal badge on their chests.
Margaret had been dealing with Flayers with the Defense Force during this time, so she was well aware of the meaning of this badge; these soldiers were elites from the Defense Force.
Margaret also recognized that one of the soldiers, wearing a sergeant's rank, was named Dmitri, an elite veteran who had ventured into the city's sewers multiple times to hunt xenos.
And the squad he led were all elites who had at least executed one xeno-hunting mission.
While Margaret and Dmitri were attempting to breach the door with Thermo-meltdown bombs, the fierce battle inside the tomb had entered a white-hot stage.
After suffering a considerable number of casualties in the initial phase, the two Tech-Priests quickly analyzed the enemy's characteristics and swiftly adjusted their strategic deployment.
With the assistance of the Sisters of Battle, they further stabilized the front line while also beginning to counterattack with the Adeptus Mechanicus's heavy weaponry at their disposal.
It must be said that the Adeptus Mechanicus has good things; even the galvanic rifles in the hands of ordinary Adeptus Militarus Skitarii could cause significant effective damage to Necrons.
Not to mention terrifying weapons like grav-cannons, which could directly crush the Necrons' living metal bodies.
This weapon, capable of distorting gravity, was especially effective when dealing with small targets like Canoptek Scarabs; basically, one shot could crush a large area.
Moreover, due to Alex's previous reminders and warnings, these two Tech-Priests had brought many of their hidden treasures, so as they gradually stabilized their position, they not only withstood the Necrons' attacks but even had the spare capacity to clear some Necron transfer hubs located around them.
Although Necrons primarily use warp gates to deploy their armies, they actually possess individual teleportation technology.
It must be admitted that these metal skeletons' technology in this regard is truly heaven-defying; they can equip every Necron with a teleportation device, allowing them to teleport back to the Necron Tomb for repairs when they are about to be destroyed, and then teleport back to the battlefield in the same Manner to continue fighting.
Even if their core is destroyed, the consciousness of these Necrons will be uploaded to the Rebirth Protocol, resurrecting them in a new body.
It is precisely because of this that Necrons are not afraid of wars of attrition; the ones who always lose in a stalemate with them are never the Necrons.
So, from the beginning, Alex had the two Tech-Priests dispatch elite squads to destroy the warp gates and Rebirth Protocol of this Necron Tomb, hoping to interrupt the enemy's continuous reinforcement.
However, he also didn't expect that the previous tomb exploration operation had still awakened the master of this Necron Tomb.
Through previous psychic prophecies, Alex captured a lot of information, and by analyzing this information, he finally understood why he was ambushed.
Simply put, the master of this Necron Tomb, a Necron Tomb Technician, after being awakened once by that Rogue Trader more than eighty years ago, specifically hired a Deathmark Sniper to guard his tomb. Once someone intruded, the Deathmark Sniper would awaken the sleeping Tomb Technician, preventing him from having his grave robbed again.
Then, Alex's previous intrusion, as well as the stasis crypt destroyed by Ovilia's Thermo-meltdown bomb before she left, all attracted the attention of the Deathmark Sniper and caused him to awaken the Tomb Technician.
The way the entire tomb seemed to be awakening when Alex left was not an illusion; it was indeed the Tomb Technician truly awakening the entire tomb after getting up.
After that, for unknown reasons, this Tomb Technician did not awaken his army to attack the humans on Rostov II, but instead cleared out the entire tomb and set it up as a trap.
When Alex led his people back here, the Deathmark Sniper's assassination was merely a signal, and the Tomb Technician, having received the signal, teleported all his armies over and sealed the tomb's stone door, attempting to trap Alex and his group in one fell swoop.
It was precisely because he saw these things that Alex was able to promptly have the entire team prepare for battle, avoiding being caught off guard by the Necrons.
It was just that he discovered it a bit late and couldn't stop the other side from closing the tomb door in time, which temporarily trapped them inside the tomb, forcing them to fight head-on.
Not only that, even the two squads that had been sent out had already been dealt with by the Deathmark Sniper.
After all, it was somewhat asking too much for Rust Stalkers and Infiltrators to contend with a Deathmark Sniper.
"Ladies, have you found a way to open the door? If we can't get out, we'll be trapped and die here." Alex didn't rush them but still sent an inquiry to the two Tech-Priests.
After stabilizing the front line, these two had been working on deciphering the tomb door, but currently, their progress seemed somewhat slow.
"Don't rush, these xeno technologies are very complex, it will take some time to decipher them." Ovilia replied to Alex; she, of course, also knew that they had to open the tomb door as soon as possible, but this truly couldn't be rushed.
