In the village of the Barbarian Mountain Clan, a large group of Manshan people gathered in front of the cave where the patriarch was, everyone looked extremely cautious, and the atmosphere in the air was very tense.

On the ground was the corpse of a Morihorn antelope, with its brain and abdomen wide open, and its brain and internal organs empty, looking very strange.

This is the Morihorn antelope that Dong and Blue brought back from the mountains and forests, and they were sent here for the first time.

"They're here again." Tuoshan's expression was the most solemn, staring intently at the corpse of the Senjiao antelope on the ground: "Let the clansmen prepare, immediately migrate and leave here, and prepare now." ”

The worry lingered in Takuyama's voice.

"Patriarch, why are you migrating?" An unknown young barbarian asked suspiciously.

"Thirty-one years the Blade Spider has appeared."

Takuyama carefully said a name, this name, is the fear and shadow of the Barbarian Mountain Clan. Those who are a little older on the field and have heard of this name are extremely shocked and even a little frightened.

"Thirty-one years of bladed spiders?" When the young Manshan people heard this name, they still didn't understand.

"You're young, you haven't heard of it. The Thirty-One Blade Spider is a dormant predator that sleeps for thirty-one years, waking up every thirty-one years, and on a large scale. After hunting their prey, they use the acid of their bodies to melt the prey's brain and internal organs, and then suck it. ”

Some of the young barbarians on the field couldn't help but retch a few times, thinking that the picture was a little scary.

"Do you know why our Barbarian Mountain Clan has been breeding here for seven hundred years, and it is still only 300,000 people?"

Tuoshan still couldn't help but open up the heavy history of the Barbarian Mountain Clan.

"When our ancestors inhabited the planet, they united with the natives and multiplied. In the following hundred years, the size of the Manshan tribe once reached four million people, and the ancestors established a large-scale Manshan town. Just when the ancestors thought that the racial civilization could be passed on slowly, a terrifying thing appeared, which was the thirty-one year blade spider.

Six hundred years ago, thirty-one years ago, the Bladed Spider first attacked our race, and the catastrophe that killed three million people, and the ancestors finally chose to migrate. Losing the protection of the original town, the population became smaller and smaller during the migration, which was the first large-scale loss of the Manshan civilization.

Later, a second perch was found, and the population slowly increased, and after two hundred and seventeen years, the size of the roost reached more than 8 million people, and near the roosting point, a large-scale thirty-one blade spider appeared again, and the number of people slaughtered by the tribe was sharply reduced to 1.5 million. After the catastrophe, the remnants of the tribe divided into five parts and migrated in different directions, which was the second large-scale loss of the Barbarian Mountain civilization.

Later, our sub-group encountered another thirty-one blade spider, and our ancestors combined with book records to finally find the characteristics of this species. After sleeping for thirty-one years, and then in a season when the temperature is right, they wake up on a large scale, hunt enough food, and then mate, then grow wings, disappear overnight, and fly to the bottom of a river in the land to sleep.

Their offspring slowly develop in the belly of the mother spider until they break out of the eggs thirty-one years later, feed on the body of the mother spider, and even eat other identical litters to grow rapidly, and finally leave the water to hunt for food, and the brain marrow and internal organs of the beasts are their food. ”

Takuyama said, his voice trembling a little.

Every thirty-one years of blade spiders appears, it is the arrival of a great disaster.

He didn't know what happened to the sub-tribes that migrated to other places, but their tribe, after experiencing disasters more than three hundred years ago, migrated several times later due to other disasters.

When they left their original place to settle on this land because of a drought, the size of the ethnic group was only tens of thousands, and now it has grown to a scale of 300,000.

"Can't you kill them all?" Tuoli asked curiously.

"It's difficult, they are very dangerous, they are very numerous, the blade is highly poisonous, if you are stabbed by it, you will die in a short time, and the scale is large, once you appear, all life around you will be extinct. They don't eat anymore until they're full. Takuyama sighed.

Woowoo......

As soon as Tuoshan's words fell, the horn of the tower in the village sounded, and the people of the Barbarian Mountain tribe on the field all changed color.

The village tower is a watchtower to prevent large beasts from attacking, and when this horn sounds, it means that the village is in a state of emergency.

"Patriarch, a thirty-one-year blade spider has appeared on the left side of the village, coming in our direction." A barbarian rushed over and stopped in front of Takuyama, his voice tinged with fear.

Takuyama's hands and feet were cold for a moment, and it came too quickly.

"Immediately let the people of the clan leave towards the rear of the village, and inform Mr. Taku of leaving."

Chen Mo was directing the robot to repair the light-speed engine, and the radar of the spaceship suddenly alarmed, and he knew that an invasion was coming.

"What's wrong?" Chen Mo looked at Tuoli with an anxious face.

"Grandpa said, thirty-one years of bladed spiders appeared." Takuli said breathlessly.

"Thirty-one years of bladed spiders? What is it? ”

"A very dangerous beast." Tuoli said anxiously: "Grandpa told you to leave quickly, the village is in danger, and the clansmen are fleeing." ”

Belch?

Chen Mo was stunned for a moment, what other danger could there be on this planet against him? But it may be dangerous for the Barbarian Clan.

"You go inside the spaceship first, and I'll take a look."

"Sir, it's really dangerous, you can't go." Tuoli anxiously pulled Chen Mo.

"Forgot I could fly? It's still amazing. Chen Mo said.

Seeing the battle armor covered by Chen Mo, Tuoli suddenly remembered the scene when he saw Chen Mo for the first time, and finally let go of Chen Mo.

"You go and hide in the spaceship, it's safe inside." Chen Mo let Tuoli enter the spaceship, and the battle armor floated into the air, flying towards the left of the village where the radar indicated that a large red dot had appeared.

Countless monsters were coming out of the mountains and forests, approaching the village.

This is what Tuoli said about the thirty-one year blade spider, a kind of alien.

Thirty-one year blade spiders look like spiders, and a little like octopuses, but the legs are not soft, six long limbs like blades of more than one meter, with serrated teeth on the blade ruler, faintly hinting at black luster, sharp claw blades, which is the origin of their name, in bucket-sized heads, four eyes flashing with cold-blooded cruelty, and a short mouth.

The warriors of the village were resisting the approach of the blade spider, Jing Ge was also in the middle of the escort, and the villages behind were quickly fleeing towards the back mountain, and the scene was a bit chaotic.

The people in the village were all risking their escape and defending against the thirty-one-year blade spider, and they didn't notice Chen Mo's arrival at all.

Chen Mo's height rose again.

At this height, you can see that in the distance, dense blade spiders are emerging from the large lake not far from the village, extending to the forest near the village.

And not only in this direction, but also in other directions of the Great Lake, but summoned by the screams of the blade spiders, many blade spiders are coming in the direction of the village, and there are hundreds of thousands.

"Lair?"

Chen Mo stared at the lake in the distance.

At this distance, if you drop an atomic bomb, the entire village will be destroyed, but Chen Mo does not have bombs and high explosives that are too powerful, and they may not be able to kill these aliens, so they can only use other ways.

"Patriarch, let all the warriors of the clan go back to guard the village, and leave it to me." Chen Mo shouted at Tuoshan below.

"Sir, do you have a way?"

Tuo Shan noticed Chen Mo in the air, his expression was overjoyed, he knew that Chen Mo's machinery was very powerful, if Chen Mo had a way, he would definitely be able to help them solve this problem, maybe in the future, the barbarian mountain clan would no longer be afraid of the threat of the thirty-one year blade spider.

"It's a very simple thing." Chen Mo said.

During this period of contact, Chen Mo had a good impression of the alien race of the Barbarian Mountain Clan, although he was warlike, he was very simple and friendly, at least he would not be repulsed and guarded because Chen Mo was an outsider, and he was also very enthusiastic.

"You just guard the village and prevent the lone from entering the village."

"Is there really a way?" Takuyama hesitated.

"Well, just do what I say, it's easy."

"Okay."

Tuoshan agreed, Chen Mo was a visitor from outside the sky, with incredible spaceships and machines, and a god-like existence, so he chose to believe in Chen Mo.

Chen Mo took out a small container the size of a thumb from inside the battle armor, which contained a little gray powder on it.

"Here we go."

Chen Mo opened the small container and threw it down directly, a very simple matter. Gray powder is a nanobot, and for this planet, this is a dimensionality reduction blow.

Tuoshan, Jing Ge and the others didn't expect Chen Mo to just throw a small thing down, and they were stunned at the same time. The small container fell to the ground, and there was no movement, which made the barbarian warriors who saw this scene stunned, and they didn't understand what Chen Mo was doing.

One breath, two breaths...... Ten breaths later, there was still no movement.

Thirty-one years the blade spider is climbing the protective fence of their village, this is their last line of defense, if they enter the village, the massacre will begin, not everyone in the clan is so strong, the old and weak women and children under these monsters, there is no possibility of survival at all.

"Sir, this is not a joke." Takuyama is already in a hurry.

Chen Mo used a laser to sweep the bladed spider that climbed the fence, and said lightly: "It's started." ”
