Up or down? Albert couldn't tell. The knowledge he had was not useful in the tower in front of him.

Wang Xiaotian couldn't help but say: "There should be some complicated equipment below, can you understand it?"

Tang Yunjin and Albert shook their heads at the same time.

Wang Xiaotian said again: "I think that if you want to see the situation outside, you should go up." ”

Tang Yunjin and Albert exchanged glances and said, "Then let's go up and have a look." ”

The people immediately went up the stairs.

Wang Xiaotian stood on the fence and glanced around. Suddenly I found that there was a passage on the other side of the fence, connected to a metal column!

Albert also saw the passage and couldn't help but ask, "What's that?"

Wang Xiaotian dragged Albert over and stood at the entrance of the passage to observe carefully.

Where the passage connects to the metal pillars, there is a pattern of a skull, and underneath it is written the text of the old era.

"WARNING! Beware of Radiant Particles! Please enter in protective clothing. ”

Albert did not recognize the words and asked, "What is written?"

Wang Xiaotian said: "This is a warning, saying that there are radiation particles inside, and you need to wear protective clothing when you go in." ”

Albert didn't believe Wang Xiaotian. He turned his head and glanced at Tang Yunjin.

Tang Yunjin nodded, signaling to him that Wang Xiaotian didn't lie to him. Then, he asked, "What are you doing here?"

Wang Xiaotian looked around and said, "It should be an overhaul entrance." With such a complex piece of equipment having to run for a long time, how can there be no problems at all? Of course, there must be an entrance and exit to facilitate maintenance. ”

Tang Yunjin said: "What are the radiation particles?"

Wang Xiaotian spread his hands, "How do I know? Maybe it's the beam that killed those strange birds." ”

Tang Yunjin and Albert were a little flustered.

Albert hurriedly said: "Let's go up and see if there is a way to observe the situation outside." ”

The crowd walked up the stairs in a circle around the metal pillars. The difference between the two layers of fences is about ten meters. After three or four turns, they finally came to the 11th floor.

Wang Xiaotian estimated that this floor should be the base of the tower. This level, unlike the others, has small doors in the rock wall that are large enough for an adult to enter and exit.

There are also some words written on these small doors. Some wrote: "1130-1", "1130-2", "1130-3", "37-1", "37-2", "Observation 1", "Observation 2", ...... Wait a minute. Looking at the name, you can also see that some of these should be weapon models, and some should be single-function observation rooms.

Tang Yunjin walked to a door that said "Observation 4", looked for a long time but did not find the doorknob, reached out and pushed the door, but did not move.

He looked back at Wang Xiaotian and said, "How do you open this?"

Wang Xiaotian shrugged his shoulders, "How do I know?"

Albert laughed, "No kidding. Sesame opens the door is our Canaanite Commonwealth......" Before he could finish his words, his smile froze.

For he saw that door open silently.

Albert was shocked, "Is it really a sesame open door?"

Tang Yunjin shook his head, "No, but I found a button on the door, press it, and the door opens." ”

Albert's face returned to normal at this time, "I'll just say, how can you use the defense system of the Eastern Chu Kingdom, the ancient story of our Canaan Federation, as a password." ”

He pulled Wang Xiaotian to the door with "Observation 6" written on it, looked for it carefully, and sure enough, he saw that there was a very inconspicuous small button in the center of the door.

He reached out and pressed the button, and the door opened silently.

The light inside the door was not bright, and Alberta walked in with Wang Xiaotian.

It is not a room, but a corridor about one and a half meters wide and five meters deep. As they entered, the wall facing the door suddenly cracked, revealing what was going on outside.

Walking to the wall, Wang Xiaotian found that there was a layer of transparent, glass-like things on the wall, which did not lead directly to the outside.

He was secretly disappointed in his heart. Because he had planned to find an opportunity to jump out and escape if the observation room led directly to the outside. Now, this plan has only to fail.

That layer of glass-like transparent stuff should be specially made. Because when you look outside through it, you can't see the scenery outside, only a large red dot.

Albert didn't know what the red dots were, and asked, "What's going on? Why can't you see what's going on outside? What is this big red patch?"

Wang Xiaotian explained: "That large patch of red is made up of many red dots. Each red dot represents a strange bird. ”

Albert pointed down and said, "The strange bird down there, too?"

"Nope. Below are the monsters. ”

Outside the tower.

In the sky, huge strange birds, densely packed, covering the sky and the sun, surged towards the fence system like dark clouds.

On the ground, countless monsters were rushing. The monsters looked like saber-toothed tigers, with two large upper canine teeth, thicker and longer than ivory, exposed to the outside of their lips, glowing with a miserable white phosphorescence.

This monster is huge, surpassing an elephant. What's even stranger is that these monsters are not covered with hair, but are covered with scales. The tail is thick and long, the ends are swollen into balls, more than half a meter in diameter, and it is also covered with scales.

As you can imagine, if you are hit by this huge tail ball, it will be sour......

There are countless strange birds flying in the sky, and the dark clouds are overwhelming, and the sky is not visible.

Countless monsters on the ground galloped, dust flew and trembled.

This situation, even the battle-hardened generals, are not moved.

Zhou Ziheng stood under a tall tower, looking at the monsters and strange birds in the distance, and couldn't help but feel worried.

There are more strange birds in this wave than in the previous wave, and there are also an equally large number of monsters. Can the fence defense system resist it? How did the previous beast tide resist?

I wonder if the large weapons in the army can deal with these monsters?

Do you want to contact the military headquarters and transfer the Third Frontier Army, or directly transfer the corps directly under the military headquarters?

-----------------Partition---------------------

Under another tower. On the hillside to the north, the carcasses of four or five strange birds were scattered. Moli stood on the back of one of the strange birds. In the back of the strange bird, there was a bone javelin that Mo Li had originally carried on his shoulder.

The javelin, which is nearly two meters long, is only less than thirty centimeters exposed at the moment. Mo Li grabbed the javelin and jumped high.

The javelin was pulled out from the back of the strange bird, and there was not a trace of blood. After the javelin was pulled, the wound of the strange bird spurted rancid black blood. If Mo Li doesn't jump up, he will definitely be splashed.

Hyunyoung stood in front of the cave and raised his hand to kill a strange bird on the ramp with a single shot. Then he put away his gun and went into the cave, came to the mountain wall, and pulled down the iron rod in the depression of the mountain wall.

A pleasant female voice sounded, and the door opened.

Mo Li hurried in with a javelin. Xuanying looked at him and ordered, "Mo Li, follow me." Remember all my actions. ”

Mo Li was stunned for a moment and said, "Fourth sister, don't say so sad, okay? I don't want you to have anything." ”

Xuanying was slightly stunned when she heard this, and then smiled: "Where do you want to go." I'm here for you to remember my steps. Next, we'll split up into towers and activate the fence defenses. ”

The two of them walked quickly to the second fence, a small door with a warning written on a metal column.

Xuanying stretched out his hand and pressed it in the middle of the word "mouth" of "police". Mo Li was stunned for a moment. He wouldn't have thought that the middle part of the word "mouth" would be a button!

A pleasant female voice sounded: "The operator identification system is activated." Please state your system identifier. ”

Xuanying said loudly: "RLMYFY021, 42, 39, 7. ”

After a while, a pleasant female voice sounded again, "The system identification code has been verified." You can give an operation order. ”

Xuanying said: "Activate the local active defense mode." Turn on the automatic charging system of the machine. Charge mode, 4. ”

The order is confirmed. The native active defense system is activated. Automatic Charging System Activation, Charging Mode, 4. ”

Xuanying said: "The operation mode of this machine is locked. Unless you receive a new command, or after a long period of confirmation that the environment is not a threat, you can switch to standby mode. ”

The order is confirmed. ”

Then, a low humming vibration sound, from the distant underground, came up in waves, and the huge metal column began to tremble.

Xuanying walked back with Mo Li.

She said as she walked, "Have you memorized all the operation instructions just now?"

Mo Li nodded and said, "Remember." I just don't know what it means. ”

Xuanying was silent for a moment and said, "I don't know either. I didn't even have time to ask, and the man died. In fact, even if he lives, I'm afraid he can't tell. He was only a system maintenance engineer and was not involved in the system design. ”

"However, the more than ten beast tides in the past have all been operated in this way, and this time it should be no problem. ”

Mo Li nodded, and then asked tentatively, "Fourth sister, how many people know about this operation order, are they safe?"

Xuanying thought for a moment and said, "Before you, there were at least ten people who knew. As for the insecurity...... Well, for more than a thousand years, there have indeed been many ambitious people who have coveted the power of the defense system. ”

"However, without exception, they all failed. Because of this system identification code, it can only perform basic operations, and there is no higher-level authority at all. Moreover, the fence defense system has a single function, and there is no way to take away these powerful weapons. ”

Mo Li nodded and said, "That's good." Fourth sister, how do we divide the tasks?"

Xuanying said: "You go east, I go west." Once it's all activated, come back and join me. The giant tower doesn't need to be activated. Battles of this magnitude are not needed. ”

Mo Li asked curiously, "What kind of battle are they used for?"

Xuan Ying recalled for a moment and said, "I remember that when they were first designed, they were used to intercept outer space attack weapons and strike at the outer space fleet. ”

"All the giant towers of this system, if the energy is fused with all their strength, the particle beams emitted will have a range of more than 500,000 kilometers, which can destroy Solar System-class warships. ”

"As for these 100-meter-high towers, they were later built in response to the beast tide crisis. Their maximum lethality is less than a hundredth of that of those giant towers. ”

As they spoke, the two of them had already come out of the cave.

Xuanying pointed to the bottom of the mountain and said, "Go down from here, there is a road on the hillside that was originally built. ”

Mo Li nodded and said, "Okay." ”

Xuanying said again: "Also, if someone is also activating the tower, don't clash with them, just say 'I was ordered to come and activate the human destiny defense system'." However, the heart of guarding against others is indispensable. Be careful. ”

Mo Li nodded and said, "Fourth sister, take care." Then the rabbit fell and jumped down the mountain.

-------------------Partition--------------------

Wang Xiaotian felt that the entire tower was trembling slightly, and the red dots on the screen were disappearing rapidly.

Every red dot disappears, representing the destruction of a monster or bird.

However, Wang Xiaotian knew it very well in his heart. These monsters aren't the biggest trouble. Those little monsters that are ignored by the defense system are the troubles they need to face.

After a while, the red dots on the screen are almost all gone. At this time, a pleasant female voice sounded in the tower, "The short-range defense system is activated, and the energy system is transferred to charging mode." ”

"Warning, warning. 37-5, 37-7, 1130-4, 1130-6, 1130-10, Gaoping dual-purpose rapid-fire guns are out of order, please overhaul. Please overhaul. ”

Wang Xiaotian and Albert glanced at each other, and then the two walked out at the same time.

Although the defensive weapon failed, they couldn't deal with it at all, but if they didn't look at it on the spot, they were very unsure. This is actually a normal human thought, also known as the psychology of joining in the fun. The more laymen they are, the more they like to join in the fun.

When he went out, Wang Xiaotian saw that Tang Yunjin and two of Albert's subordinates also came out.

Tang Yunjin asked first: "What's the matter with the malfunction?"
