Almost at the same time.

Outside the city of Yunzhou City, in front of the defense line in four directions, the group of snakes that were attacking frantically suddenly stagnated and stopped acting collectively.

Lying on the ground, like a zombie, it lost its vitality.

On the defensive line, the soldiers who fired guns and artillery, seeing this scene, subconsciously stopped firing and looked surprised.

"What's going on? Why don't the snakes move?"

"You second goods, do you want the snakes to continue moving?"

"No, I'm just curious, if the snakes don't attack, will there be something brewing?"

"Then who knows, report it and wait for the decision above. ”

"Let's hope the snakes will retreat, or our ammunition will bottom out. ”

"Yes, I don't know what these cold-blooded animals are stimulated by, so crazy!"

“......”

The warriors behind the defensive line, breathing a sigh of relief, at the same time, whispered.

The officers on the side, listening to their ears, did not stop them, but only kept everyone vigilant.

The battle between humans and snakes, until now, the soldiers who have entered the city are all tense to the extreme. At this time, if it is forcibly suppressed, it will collapse directly.

In fact, not to mention the soldiers below, even all the officers, they were also relieved at this moment.

In the face of an overwhelming, dense group of snakes, a frenzied attack, no one has the capacity to withstand it, heavier than those of them who are on the defensive line.

has been able to persist until now, relying entirely on tenacious willpower to resist!

At this time, the snakes stopped attacking, and everyone breathed a sigh of relief.

Soldiers stationed on the defensive line get a short rest.

The officers reported the situation at the scene and set up a temporary command center on a hill 10 kilometers west of Yunzhou City.

In the temporary command center that received the news, in a spacious military tent, everyone watched the projection images captured by the drone, and there was silence.

Half Ringing –

"The source of the snakes' madness should be gone. A middle-aged man in formal clothes suddenly spoke.

"Are you sure?"

On the side, an old man frowned and said, "There are many situations when the snakes stop attacking, and it doesn't necessarily mean that the source has disappeared. ”

"Yes, we sent so many people in before, looking for the source, but we never found it. Now that the snakes have stopped attacking, how do you know that it is the source?"

"I think we should take this opportunity to speed up the evacuation of the crowd in the city!"

"There are more than a million people in Yunzhou City, and no matter how fast we are, we won't be able to evacuate much! If we don't do it well, maybe it will stimulate the snakes and make them even more crazy!"

"Well, where did these snakes come from, have you found them? As long as we find the source of the snakes, we can cut off their follow-up reinforcements! Without reinforcements, it is only a matter of time before they are eliminated!"

"I didn't find it, these snakes seem to have come out of the ground. No one knows where they come from. ”

"What are you talking this nonsense for? If you want me to say, now, throw a few incendiary bombs down and destroy most of these long worms!"

“......”

The people in the tent were gossiping and talking.

Some advocate a counteroffensive, some advocate clarifying the source, and some advocate evacuation.

Noisy Huan-

"Everyone, stop arguing, look at the projection screen, the snakes have retreated!"

A voice suddenly rang out.

"What?"

Everyone exclaimed, and immediately, they looked up at the picture captured by the drone.

I saw that outside the defense line, the snakes that were originally densely packed together, like a colorful blanket, at this moment, like the sea water at low tide, withdrew from the defense line and retreated to the rear, until they disappeared into the mountains and forests.

The whole process, in less than three minutes, made the snakes that were almost buried in Yunzhou City all gone.

If it weren't for the fact that the ground outside the line of defense was full of potholes after the shelling, the people in the tents would still think they were dreaming.

"Didi!"

The chime sounds.

A military technician wearing headphones and operating a computer suddenly took off his headphones and said excitedly to everyone, "Report chief, the snakes in Yunzhou City have all retreated!"

"Good!"

The old man, who had been frowning all the time, heard this, his eyes shone brightly, and he shouted with joy, "Okay, great! Everyone doesn't have to fight, no matter what the reason, since the snake group has retreated, it is worth celebrating! Of course, there is no need to rush to withdraw the defense line outside Yunzhou City, not only can it not be withdrawn, but it is also necessary to send people into the city again to do a good job of pacifying and defending it!"

"Yes!"

Everyone responded in unison.

The voices fell, and they dispersed to carry out the order.

Except for the middle-aged man in formal clothes, he stood in place, looking at the picture on the projection screen, and fell into deep thought.

Why did the snakes retreat?

He was sure that 90 percent of the reason was that the source that stimulated the snakes to go crazy had disappeared!

Or, someone took it!

......

Yunzhou City.

One kilometer underground.

"Goo!" "Goo!" "Goo!"

Eerie bird calls rang out in the enclosed underground caverns.

I saw three birds that looked like penguins, jumping and jumping on the ground around an area.

The four earth dragon sparrows, uh, no, to be exact, three earth dragon sparrows, were very curious about the sudden disappearance of a boulder as big as a house. Jumping from Su Fang's shoulder to the ground, where he stood in front of the boulder, he spun around.

I don't know what they can see in this dark underground cavern.

Then there was another earth dragon sparrow, curled up at Su Fang's neck, its claws firmly grasping the collar, and making a slight "toot" weird snoring sound.

This sleepy old ten, no matter where he is, can fall asleep quickly!

Su Fang admired it from the bottom of his heart.

After collecting the boulder that caused the snakes to go berserk, Su Fang did not immediately rush back to the surface for verification, but wandered around this closed underground cave.

As a result, after only half a turn, I found that in the northwest corner of the top of the cave, there was a large hole that was inclined to the surface.

Since coming down to the ground, Su Fang has released his innate true qi, forming a shield to protect himself from being invaded by various breaths underground, and because of his innate true qi, Su Fang can hold his breath for several hours.

And because he keeps the "spiritual eye" open, even in the dark place of the cave, Su Fang can see the things around him, without fear or danger.

However, at this moment, looking at the cave above his head that was sloping upwards and leading to the surface, Su Fang was suddenly stunned.

Out of thin air!

The boulder he took away actually fell from the ground!

Because the area where the boulder stood before was right at the exit of this sloping cave.

The size of the cave is about the same as the size of the boulder.

Su Fang can imagine that many years ago, the pitch-black boulder that he took away fell from the sky, smashed into the earth, smashed a big hole, and went deep into the ground for a thousand meters.

Finally, stop at this enclosed underground cave!

According to this speculation, the pitch-black boulder may not be a product of the earth, but a meteorite from outside the sky!?
