"What is a spaceship?" Op was stunned and asked.

Zou Chuan suddenly didn't know how to answer the question that even a three-year-old child in this human alliance knew, but this young man didn't know.

"What's the matter with a spaceship? Can it fly? Grabbing Op's arm tightly, Ruth asked cautiously, in fact, Ruth had been quietly observing this big brother, and this big brother had no expression on his face, which made her very puzzled.

"Well, you can fly."

"Does that bird fly high?" Ruth asked, suddenly pointing to the birds hovering in the sky.

"There is ......" Zou Chuan glanced at the sky meaningfully, and suddenly felt a chill on his back, only to see countless birds flying in the sky far away, black and pressing, like black

The clouds are general, because they fly too high, Zou Chuan can't see the specific appearance of these birds with his eyes, but from the flight posture of which birds, Zou Chuan can definitely judge that these birds are definitely birds of prey.

Just when Zou Chuan was stunned, those birds fell like a violent wind, and the direction was the colorful shell insects more than 200 meters behind him.

Thousands of birds flutter down at the same time, layering on top of each other, obscuring the sky and the sun, which is spectacular......

Immediately, the hill-like colorful shellworms were tightly blocked, and some birds kept flying up and down, and some were still fighting with each other for something.

"What are they doing?" Zou Chuan couldn't help but ask.

"You don't know about eating spotted shellworms?"

“……”

Zou Chuan couldn't help but have nothing to say again, he couldn't imagine how these birds ate the colorful shell insects, according to Zou Chuan's understanding, the exoskeleton of these colorful shell insects was harder than steel, and they would not decompose, and when humans disposed of the corpses of the colorful shell insects, they had to use antimatter incinerators.

However, there was no need for Zou Chuan to think about it at all, Op actually turned around and strode towards the corpse of the colorful shell worm.

"Let's go, it seems that you don't know much about this place, I'll take you to have a look."

"These birds don't hurt?" Zou Chuan couldn't help but be stunned, he felt the ferocity of the empty birds, such a large-scale flock of birds is sometimes more dangerous than the beast, because, the bird of prey flies in the sky, has a large area of activity, and its attack power is often fast, and the damage caused will be multiplied by the speed.

"Don't be afraid!" Op proudly raised his longbow with a confident expression.

Zou Chuan didn't speak again, for him, this is a strange planet, and he needs to understand it through young people.

The three of them quickly approached the colorful shell insects surrounded by layers of birds of prey, and what made Zou Chuan strange was that some of the birds of prey on the periphery saw them approaching and actually avoided them from a distance.

In just a few minutes, Zou Chuan saw clearly the appearance of these birds of prey, the birds of prey are wings beyond two meters, the feathers are not gray, mixed with some black spots, it looks very unremarkable, however, the mouth of the raptor is barbed, black and shiny, at the same time, a pair of claws are also extremely amazing, extremely sharp.

What impressed Zou Chuan the most was that the pea-sized eyes of this bird of prey were extremely vicious, and the fierce light was revealed.

From Oppe's mouth, this bird of prey has a very disgusting name: corpse bird.

Zou Chuan also knew why Aopu was not afraid of these birds, because these birds never ate living things, only corpses, so they got the notoriety of a corpse bird, and these birds have a natural fear of humans, when the three approached, the eyes of the corpse birds showed a frightened expression, lest they avoid it.

Soon, the three of them approached the colorful shell insects, and countless layers of corpse birds flew away, flapping their wings and watching the three of them in the air.

At this time, Zou Chuan didn't pay attention to the corpse bird that covered the sky and the sun, because he was already shocked by the side in front of him.

The colorful shellworm weighing more than ten tons had shrunk by more than half at this time, and the hard exoskeleton on the body was eaten clean by the corpse bird, and the intertwined muscles under the exoskeleton were also swallowed up, even the body fluid was also sucked up at all.

Zou Chuan believed that if they had come a few minutes late, the corpse of the huge colorful shellworm would have disappeared into thin air.

Zou Chuan was extremely surprised in his heart, he had a deep understanding of the hardness of the exoskeleton of the Colorful Shell Worm, it was impossible for ordinary metal weapons to hurt the Colorful Shell Worm, how hard should the beaks and claws of these corpse birds be?

What makes Zou Chuan feel even more incredible is how these corpse birds digest these exoskeletons that are as hard as metal?

So everything, is a mystery.

However, it is undeniable that the beaks and claws of these birds are absolutely invincible if they are made into tools.

Immediately, Zou Chuan knew the value of these mouths and claws from Opple's mouth.

"Looks like we've had a big harvest lately." Op muttered as he looked at the corpse bird that covered the sky.

"What's the catch?" Zou Chuan asked.

"You don't know?"

Zou Chuan didn't answer, just shook his head.

"You see, those corpse birds whose feathers have turned pure black are close to death, and corpse birds have a habit of gathering together in large numbers in batches when they die, flying over this grassland, to the death desert on the other side of the Jingguan River to wait for death, after they die, their bodies decay, leaving behind hard skeletons and beaks, as well as sharp claws, these things can be made into armor locks*, arrows for bows and arrows, and small weapons such as daggers......"

Listening to Opple's explanation, Zou Chuan finally understood why Ruth's arrows could easily shoot into the exoskeleton of the colorful shell insects, it turned out to be because of the arrows made from the body parts of these corpse birds.

The beaks of these corpse birds can easily tear through the exoskeleton of the colorful shellworm, let alone shoot through the exoskeleton, and with enough strength, it is not a problem to shoot through the alloy.

"Do many people collect the remains of dead birds?" Zou Chuan immediately thought of the Human Alliance that it was now lacking weapons that could deal with the colorful shell insects, and if it could take away a large number of weapons made from the remains of corpse birds through the space button, it would reverse the decline of the human race.

"Many, many, corpse birds have a very long lifespan, up to hundreds of years, although a large number of corpse birds die every year, but, because the demand of human beings is too great, and there are too many unknown existences in the Death Desert, therefore, the weapons made of any body part of the corpse bird are relatively expensive, of course, as long as there is money, there are still a lot, the number of corpse birds is too large......"

Opu is a very patient person, explaining to Zou Chuan very carefully, of course, the main reason is that Opu has never been taken seriously, and Zou Chuan's ignorance gives him a sense of accomplishment that is valued.

"If it's so expensive, why not just hunt it?!" Zou Chuan was a little puzzled.

"Hunt! Why hunt?! Op looked at Zou Chuan with wide eyes in surprise.

"......" Zou Chuan was speechless, he didn't expect Aopu's reaction to be so big.

"I really kind of doubt that you grew up with Gallon......"

"There's a lot I don't understand, and I hope you can explain." Zou Chuan did not argue and shifted the topic.

"Don't you know that the animal bones in the first part of the Gallon Star 1 (6) k .1 (6) оМ version are not used, such as the colorful shell worm, a huge creature, after they die, the hard exoskeleton will take more than five hundred years to be completely weathered even if it is in the open air in the grassland, and these exoskeletons will produce a toxic powder after weathering, which is very harmful to human eyes, if the gallon star has no corpse birds, it is really unimaginable, the entire plain will be occupied by dense animal bones, Moreover, some of the fierce carnivores of the Gallon Star are wrapped in exoskeletons, and you can imagine what a terrible thing it would be if the colorful shellworms were not digested, and the carcasses weighing dozens of tons were piled up on the savannah......"

"Besides, although the bones of corpse birds are precious and rare, as long as you have money, you can hire a large number of people to search for them in the Death Desert, and there is no need to kill chickens and eggs to hunt corpse birds......

…… Under a burst of explanations from Aopu, Zou Chuan understood the importance of corpse birds to this planet, corpse birds are equivalent to a natural scavenger, it is an indispensable species in this biological chain, without this species, this planet will become uninhabitable, there are colorful shell insect corpses everywhere like a hill, it is indeed a big thing to disturb the scenery, and Zou Chuan has seen the reproduction speed of colorful shell insects, if there is no corpse bird, it is estimated that it will take hundreds of years, This vibrant savannah is estimated to have become a graveyard for colorful shellworms.

In short, without the corpse birds, it would be a great disaster.

The miracle of the creator made Zou Chuan sigh, he had always thought that the future star was magical enough, but he didn't expect that the species on this planet were even more magical.

However, Zou Chuan's knowledge of this planet was very limited, and immediately, he was stunned by the scene in front of him,......

Just when he sighed and looked at the remains of the colorful shell insects from the empty corpse bird, he saw that the remains of the colorful shell insects had only half a hard exoskeleton left, and some of the body fluids in it had been cleaned.

Of course, what frightened Zou Chuan was not the corpses of the colorful shellworms, but the sight of some translucent soft tubes smaller than straws crawling out of the cracks in the remains of the spotted shellworms and disappearing into the turquoise grass.

"This is the root of the tree, the corpse bird only eats these bones, and those muscles and bodily fluids are the food of the tree......"

This time, Aopu didn't wait for Zou Chuan to ask, he was already used to Zou Chuan's ignorance, and immediately pointed to a big tree hundreds of meters away and explained.

"Rest assured, the root system of this tree can only absorb immobile corpses, and has no ability to harm moving objects, and nothing can easily break free from the shackles of the root system, but don't get close to the radius of fifty meters around the big tree......

……

From Opple's mouth, Zou Chuan once again confirmed that the trees were fearsome predators, even if they were humans, and they were also the recipes on its menu.

Once again, the three of them headed for a satellite city next to the capital of the Gallen Empire, which was guarded by Opp's people and was responsible for resisting the invasion of the three southern states.

Brother Chuan, I think you have a lot of strength, why don't you sign up for the army with me? Along the way, Aopu did not have the initial fear of Zou Chuan, but instigated Zou Chuan to join the emperor ** team, of course, Aopu privately hoped to join the army with Zou Chuan and take care of each other.
