The Shadow Keep, no, it should be called the Doomsday Shadow Keep now, has just begun a massive expansion.

Standing at the top of the fortress, William couldn't help but smile as he watched the expansion work that began simultaneously on the left and right sides.

At this moment, there was a roar in the sky, and three landing transports broke through the storm layer and flew towards the fortress. They are cosmearly damaged, but the main structure is still intact. William's eyes lit up with satisfaction, and with the supplies of these three transports, he would be able to expand the smelting plant that was most urgently needed and process a large number of metals.

The door opened behind William, and Joseph walked out, came to William's side, and said, "Cambrian has made a new discovery, guess what?"

William smiled slightly and said, "If you say that, it must be a good thing." ”

Joseph laughed and said, "A vein, a vein! a copper mine, less than 200 kilometers from us." It's just that it's a bit deep, and we have to dig 3,000 meters to get there. ”

William's smile became even more pronounced, "That's great news. We need a lot of copper, and copper ore often has a lot of rare metals in it. We won't be short of strategic metals. ”

"The only question is, when to dig it. ”

The smile on William's face vanished. He pondered for a long time before he said: "If you want to mine, just a mining base is not enough, at least it has to be our current scale to be able to withstand the attack of the beast tide." ”

"Forget it, it's good news that there are mines, otherwise, I'll ......" Before Joseph finished speaking, he suddenly looked up and saw another transport ship rushing out of the storm clouds!

It looked miserable, with almost all of its armor gone, and even the hull of the ship badly damaged. Two of the three main engines have been burned out, and most of the attitude engines have been lost. The transport ship, which lost most of its power, fell rapidly as soon as it came out of the clouds, but fortunately, the captain was highly skilled, and directly switched the transport ship to the mode of head and tail, and turned on the only main engine to fight gravity, which slowed down the fall and successfully suspended less than 100 meters above the ground. Then the transport ship propelled with a gesture engine and slowly floated towards the fortress.

"One more transport ship!" Joseph was overjoyed and immediately ordered: "The transport ships in the air will stop landing, and all the take-off and landing fields will be set aside." The damage management and medical units will be on standby at the take-off and landing site immediately!"

The transport, which was close to total destruction, swayed into the fortress, and then constantly adjusted its attitude, and finally slapped on the take-off and landing field. The anti-gravity device on the transport ship was obviously completely destroyed, and it was able to successfully land in this situation, which is a miracle.

"I'm going to direct the rescue supplies!" Joseph hurried away.

As soon as he left, the smile on William's face could no longer be suppressed. It is a miracle that all four transport ships have successfully landed this time. Although the last transport ship was badly damaged, the main cargo hold remained intact and the cargo inside should have been there. This transport ship means a new small factory.

It seems that the name Shadow of Doom will soon live up to its name.

William was looking forward to the future, when suddenly Joseph came back faster than he had gone, and shouted, "Intelligence!

William was still calm, and when he clicked on the information transmitted by Joseph, he saw that a large patch of red appeared on the original location of the beast's nest, like dripping blood, and it was slowly surging towards this side!

"This is, the beast tide ......" William's voice was unsteady.

Joseph became extremely calm and said, "Looking at the scale, it may be a double-A beast tide." Come on, get ready to fight, I don't want to die here. ”

After the final shock, William also calmed down and immediately ordered: "According to the maximum coverage, shoot all the Javelin missiles out to me!" Immediately empty the take-off and landing field, and the transport ships in the air carrying the Javelin missiles will land first. Launch the missile as soon as it is unloaded!"

Joseph waited for his order to finish, and said, "Hopefully, by the time they come to the bottom of the fortress, only 80% will remain." ”

William said, "I'm sure I'll make the beast tide weaken by forty percent!"

"I hope so. Without further ado, Joseph hurried to the walls of the fortress and prepared to organize the defense.

At this time, one after another Javelin missiles took off into the air and quickly flew into the distance. William watched the missiles go away, and these were the only 50 missiles he had in his hands.

But he was hopeful of the landing transport ship, which was apparently carrying Javelin missiles. William quickly opened the manifest and took a look, and what he saw was a full 200 Javelin missiles!

A smile slowly appeared on William's face, and he said to himself, "It seems that it can weaken Liucheng." An A-class beast tide, at most I don't want those two construction sites. These materials can be replenished in 2 days. ”

The Javelin missile flew close to the storm clouds, and there were many shadows in the clouds, but they could not catch up with the high-speed missiles, so they could only watch the missiles go away, and then slowly retract into the clouds.

When the missile swarm flew over most of the road, a swarm of biological missiles was seen head-on.

The two groups of missiles passed by and glanced at each other. If they all have wisdom, they will probably throw a silly X at each other, and then run to their respective goals.

The beast tide's group of biological missiles finally flew above the Shadow Fortress of Doom, accelerating one after another, and roaring towards the fortress.

"So many!" On the city wall, Joseph, who was sitting in the mecha, changed his face slightly, and then ordered: "Turn on the 'umbrella' defense system and intercept it with all your might!" Don't let a damn missile fall into the fortress!"

At the four corners of the fortress, a large weapon tower was raised, and missiles were fired from the tower, facing the living missile group. Thousands of meters apart, these missiles exploded one after another, spewing out countless extremely fine heavy metal particles that sprinkled in front of them in a fan-shaped area shaped like an upside-down umbrella.

More than a dozen giant umbrellas protect the entire front of the fortress.

Metal particles are extremely fast, and as long as they are glued, they can easily penetrate the shell of a living missile and penetrate deep into the internal destruction.

However, as soon as the smile on Joseph's face appeared, it froze again!

Almost all of the living missiles were hit, apparently hit by the defenses, but a small half of them continued to move forward, just flying precariously. Another part of the missiles scurried around in the air, like bison with their tails lit. Only barely more than half of the missiles were shot down.

"Stop! immediately!" Joseph ordered in a loud voice, and then slapped himself in the face, "Damn, forget they're alive!"

If it is a human missile, the inside is quite precise, and if it is penetrated by even a single metal particle, it will explode on the spot. But the missiles of the beast tide are actually war beasts, and they have been hit by metal particles with a few small holes, and they are only treated as flesh wounds, and they can still hold on to them if they grit their teeth.

Joseph didn't have time to think about it, the mecha was already firing at full power, desperately trying to intercept the biological missile that had slipped through the net.

On the top floor of the main building of the fortress, William, who returned to the command hall, stared at the red color that represented the beast tide. Finally, he saw the red change, and then his face changed dramatically.
