After receiving the Shadow of Doom Fortress, the floating base shuttled back and forth at low altitude several times, and most of the equipment and supplies of Base 2 were moved. As soon as the personnel arrived, Chu Jungui began to repair the fortress.

The Shadow of Doom Keep was last rebuilt with plenty of room for expansion, mainly in the underground area with plenty of space for energy modules.

Chu Jungui grabbed several fusion energy modules from the two bases of the Pirate Banner, but he did not rush to use them, but dismantled a crystal power furnace from the floating base and placed it in the energy module area, restoring the power supply to the entire base.

Now Chu Jungui's men are fully manpowered, so he sent more than a thousand people to clean up the corpses of war beasts inside and outside the fortress. The Lancer's mode of disposal is to throw the corpses of war beasts outside the fortress, pile them up in a centralized manner, and then incinerate them with high-temperature flames. But in the eyes of the subject, these are valuable materials that cannot be wasted. All the corpses of the war beasts were collected and stored in cryogenic warehouses, and even the large pieces of blood that had dried up were shoveled down for storage.

There are still a lot of building materials left in the fortress, which were originally intended to be used to expand the fortress, but now they are no longer needed, and they can't be taken away, and they are not easy to destroy, so they just threw them down, but it was cheaper for Chu Jungui.

These building blocks are standard modules. Removing broken modules from buildings that need to be repaired and installing new ones can fill a large gap in a few clicks.

Ordinary building modules need to be manually installed and tightened with connections and reinforcements, and there are also a number of emergency modules that can be fixed by themselves as long as they are placed and pushed into a predetermined position. This module is designed to quickly repair damaged fortifications and restore defenses as quickly as possible.

Except for some building modules, Chu Jungui didn't find anything useful. Before leaving, the lancers even emptied all the oxygen.

Fortunately, the quarters of the fortress are still intact, so at least everyone can live comfortably without having to sleep in armor most of the time like they did at Base 2.

After the initial cleaning of the fortress, Chu Jungui removed some weapon stations from the floating base and placed them in the armored turret of the fortress. These weapon stations were not connected to the main brain for the time being, so Chu Jungui arranged for some soldiers to be stationed in the turret.

The next step was to install the stolen Cambrian in the command hall to replace the one that had been completely destroyed. This work is quite time-consuming, the Cambrian transportation and installation are very cumbersome, and the command building was blown up by Chu Jungui himself, which made it even more difficult.

It took a whole day to get Cambrian into operation, and the entire fortress was back in operation.

As soon as Cambrian was available, Chu Jungui received a piece of information that a new beast tide was gathering 200 kilometers away from the fortress.

Chu Jun is not very good at Cambrian return, but according to past experience, those who attack the Shadow Fortress are at least double-A beast tides.

To find out where the beast tide is gathering, a batch of ground-to-ground missiles copied from the pirate flag base will be useful. These missiles all have their own simple launch devices, Chu Jungui lined them up outside the fortress, and after entering the coordinates, the missiles were lifted into the air one after another and flew into the distance.

Subsequently, Chu Jungui accelerated the construction of defenses in the direction of the beast tide, specially arranged additional weapon stations, and arranged all the captured needles and umbrella defense systems in this direction.

Sure enough, just as General Chu Jungui finished arranging the defense system, a dense array of familiar small black dots appeared in the sky. The beast tide now seems to be more and more fond of using living missiles.

Just in case, Chu Jungui first launched a batch of umbrella air defense systems, and then used a sniper weapon station as the last line of interception.

Most of the hundreds of living missiles crashed into the umbrella air defense system, and only a dozen penetrated the defense system. The weapon stations in the walls and armored turrets quickly adjusted their direction and opened fire almost simultaneously, instantly detonating all the living missiles that penetrated the system.

Living missiles are constantly evolving, but the Federation is not idle, the latest batch of umbrella and needle systems have all been deeply improved, faster response, more effective interception, and even added neurotoxins specifically for war beasts.

After trying the remote-controlled weapon station and still being able to effectively intercept live missiles, the test subjects were relieved. When the second wave of live missiles hit, he only fired the equivalent of one-third of the first umbrella missile, intercepted a small half of the live missiles, and exploded the rest with weapons.

The beast's attacks were rigid and somewhat stupid, and waves of living missiles kept coming, and all of them were intercepted. At first, Chu Jun seemed to be very relaxed when he returned, but after seven or eight waves, he couldn't laugh anymore. The limited number of umbrellas and needles was running out, and the interception of the weapon station was beginning to struggle. But the living missiles seem to be endless, and a wave will appear every ten minutes.

Chu Jungui sometimes felt that the war beasts were stupid, if the war beasts combined the three waves of attacks into one wave, they would have knocked out the air defense system of the fortress a long time ago, but they would have to use the most useless tactics to add fuel.

The subject secretly rejoiced, if the war beast really became smarter, then where could he defend the fortress?

The battle was raging in the sky, and thousands of soldiers on the ground were also desperately busy, repairing the fortress as fast as possible. Most of them had experienced the attack of the beast tide, and they knew that the overwhelming beast tide was terrifying. At this time, no one dares to be lazy, and they are all working for their lives.

And just like that, the attacks of the living missiles came in waves, which lasted for several hours. Chu Jungui didn't know how many living missiles he had knocked out, and finally, a black tide line appeared on the distant horizon.

The beast tide is finally here.

This was the first time that Chu Jungui had faced such a large-scale beast tide.

At this moment, although the defense of the fortress is still a little weak, after all, the system has been completed, and the defense capability is much stronger than that of Base 2. But the enemy is just as powerful.

Chu Jungui stood at the head of the fortress, looking at the rapidly approaching beast tide from afar, and as soon as his consciousness moved, dozens of weapon stations immediately opened fire at the same time, blasting the beasts rushing to the front to the point of flesh and blood.

However, the damage of the weapon station was really limited compared to the entire beast tide, and the casualties of thousands of alien beasts were nothing at all.

The subject was as calm as ice, and while controlling the weapon station to continue to kill the beast tide, the barrel was activated at the same time.

With a few muffled toms, the top of the floating base opened, and several heavy barrels were thrown. The barrels then activated their attitude control engines, dragged their long tail lines, and slowly flew towards the tide before exploding in the air.

In an instant, countless killers were scattered in the air, clearing up patches of open space in the herd in an instant.

At that moment, a small messenger suddenly flapped its wings and flew over the battlefield, letting out a few crisp chirps.
