"What is a spaceship?" Opp asked in a daze.

“…”

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

"What is a spaceship? Can it fly?" Ruth asked carefully by holding Opp's arm tightly. In fact, Ruth had been quietly observing this big brother. There was no expression on the big brother's face, which made her puzzled.

"Yeah, you can fly."

"Is there any bird flying high?" Ruth asked suddenly, pointing at the hovering bird in the sky.

"have……"

Zou Zichuan subconsciously glanced at the sky, and suddenly felt a chill on his back. He saw countless birds flying towards this side in the distant sky, which were black and like dark clouds. Because it was flying too high, Zou Zichuan could not see the specific appearance of these birds with his eyes. However, from the flying postures of which birds, Zou Zichuan could definitely judge that these birds were definitely birds of prey.

Just as Zou Zichuan was stunned, the birds fell like strong wind, and the direction was the colorful shell insects more than 200 meters away from behind.

Thousands of birds pounced down at the same time, layered and covered the sky and the sun, making them magnificent...

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

"What do they do?" Zou Zichuan couldn't help asking.

"You don't know how to eat colorful shellworms?"

“…”

Zou Zichuan couldn't help but say nothing again. He couldn't imagine how these birds eat colorful shell insects. According to Zou Zichuan's understanding, the exoskeletons of these colorful shell insects are harder than steel and will not corrode. When humans deal with colorful shell insect corpses, they have to use antimatter incinerators.

However, without thinking about Zou Zichuan, Opp turned around and walked towards the corpse of the colorful shellworm.

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

"Don't these birds hurt people?" Zou Zichuan was stunned. He felt the ferociousness of the birds in the air. Large-scale bird flocks like this are sometimes more dangerous than beasts, because birds of prey are flying in the sky, with a large area of ​​movement, and their attack power will often be fast, and the destructive power will increase exponentially due to speed.

"Not afraid!" Opp proudly raised the longbow in his hand, with a confident expression.

Zou Zichuan didn't say anything anymore. For him, this was a strange planet and he needed to understand it through young people.

The three of them quickly approached the colorful shell insects surrounded by layers of birds of prey. What made Zou Zichuan strange was that some birds of prey on the outside actually avoided them from afar when they saw them approaching.

In just a few minutes, Zou Zichuan saw clearly the appearance of these birds of prey. The birds of prey had wings that exceeded two meters, their feathers were gray, and some black spots were mixed in the middle, which looked very unobtrusive. However, the birds of prey's mouth showed barbs, which were shiny black, and at the same time, their claws were also extremely amazing and extremely sharp when they opened.

What impressed Zou Zichuan the most was that the pair of pea-sized eyes of this bird of prey were extremely ferocious and showed its fierce light.

From Opp's mouth, this kind of raptor has a very disgusting name: the corpse bird.

Zou Zichuan also knew why Opp was not afraid of these birds, because these birds never ate living things and only corpses, so they gained the reputation of a corpse bird. Moreover, these birds had a natural fear of humans. When the three of them approached, the corpse birds showed a fearful expression in their eyes, which was afraid to avoid them.

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

At this time, Zou Zichuan did not pay attention to the corpse birds that covered the sky, because he was already shocked by the side in front of him.

The colorful shellworm weighing more than 60 tons had shrunk by half at this time. The hard exoskeleton on the body was eaten by the corpse birds, and the mixed muscles under the exoskeleton were swallowed completely, and even the body fluid was sucked without a single suck.

Zou Zichuan believed that if they came a few minutes later, the huge colorful shell insect body would disappear out of thin air.

Zou Zichuan was extremely surprised. He had a deep understanding of the hardness of the exoskeleton of the colorful shell insects. Ordinary metal weapons could not harm the colorful shell insects. How hard should these corpse birds' mouths and claws be?

What made Zou Zichuan even more incredible is how these corpse birds digested these exoskeletons that were as hard as metal?

Everything is a mystery.

However, it is undeniable that if the mouths and claws of these birds are made into tools, they will definitely be invincible.

Immediately, Zou Zichuan learned the value of these mouths and sharp claws from Opp's mouth.

"It seems that there has been a big gain recently." Opp murmured at the corpse birds covering the sky.

"What's the harvest?" Zou Zichuan asked.

"you do not know?"

Zou Zichuan did not answer, but just shook his head.

"Look, those corpse birds whose feathers turned pure black are almost dead. Corse birds have a habit of gathering together in batches and flying over the plain to the death desert on the other side of the Jingguan River. After their death, their bodies will rot, leaving behind hard skeletons and mouths, and sharp claws. These things can be made into locks of armor, arrows of bows and arrows, and small weapons such as daggers..."

Listening to Opp's explanation, Zou Zichuan finally understood why Ruth's arrow could easily shoot into the exoskeleton of the colorful shellworm. It turned out that it was because of the arrows made from the body parts of these corpse birds.

The beaks of these corpse birds can easily tear the exoskeletons of the colorful shellworms. Not to mention shooting through the exoskeleton, if you have enough strength, shooting through the alloy is not a problem.

"Does many people collect the remains of corpse birds?" Zou Zichuan immediately thought in his mind that the Human Alliance is now missing weapons that can deal with colorful shell insects. If a large number of weapons made of corpse birds can be taken away through the space button, it will reverse the decline of human beings.

"Many, many, many, and the lifespan of corpse birds is very long, which lasts hundreds of years. Although a large number of corpse birds die every year, because the demand for humans is too great and there are too many unknown existences in the Death Desert, the weapons made of any body part of the corpse bird are relatively expensive. Of course, as long as you have money, there are still many, and the number of corpse birds is too large..."

Opp was a very patient person and explained to Zou Zichuan very carefully. Of course, the main reason was that Opp had never been valued. Zou Zichuan's ignorance made him feel a sense of accomplishment that was valued.

"Since it's so expensive, why not just hunt it down?!" Zou Zichuan was a little puzzled.

"Hunting! Why hunt?!" Opp looked at Zou Zichuan with wide eyes in surprise.

"..." Zou Zichuan was speechless. He could not have imagined that Opp's reaction was so big.

"I really welcome you whether you grew up with the Gallon Star..."

"I have a lot of things I don't understand, I hope you can explain it." Zou Zichuan did not argue and changed the topic.

"Don't you know that most of the animal bones of Gallon Star are not corrupted, such as large creatures such as Colorful Shellworms. After they die, the hard exoskeletons can be completely weathered even in the grasslands. Moreover, these exoskeletons will produce a poisonous powder after weathering, which will cause great harm to people's eyes. If Gallon Star has no corpse birds, it is really unimaginable that the entire plain will be occupied by dense animal bones. Moreover, some fierce carnivorous animals on Gallon Star are wrapped in exoskeletons. You imagine, if the Colorful Shellworms do not digest, the remains of this corpse weighing dozens of tons are piled up on the grasslands, which is like a mountain of corpse wreckage..."

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

...

After Opp's explanation, Zou Zichuan understood the importance of corpse birds to this planet. Corse birds are equivalent to a natural scavenger. It is an indispensable species in this biological chain. Without this species, the planet will become uninhabitable. There are corpses of colorful shell insects like hills everywhere. It is indeed a big shame. Moreover, Zou Zichuan has seen the reproduction speed of colorful shell insects. If there were no corpse birds, it would probably take hundreds of years to become a cemetery for colorful shell insects.

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

The magic of the Creator made Zou Zichuan sigh. He always thought that the future star was magical enough. Unexpectedly, the species on this planet were even more magical.

However, Zou Zichuan had very limited knowledge of this planet. He was immediately stunned by the scene in front of him...

Just as he sighed and his eyes fell from the corpse bird in the sky to the remains of the colorful shellworm, he saw that only half of the hard exoskeletons were left in the remains of the colorful shellworms, and some of the body fluids were clean. In the past few minutes, Zou Zichuan also saw that there were still some remaining body fluids in the bones there, and now it was like it was drained with a water pump.

Of course, what shocked Zou Zichuan was not the corpses of the colorful shell insects, but saw some translucent soft tubes that were smaller than straws were crawling out of the gaps in the wreckage of the colorful shell insects and disappeared into the green grass.

"This is the root of that big tree. The corpse birds only eat these bones, and those muscles and body fluids are food for the big tree..."

This time, Opp did not wait for Zou Zichuan to ask questions. He was already used to Zou Zichuan's ignorance and immediately pointed at a big tree hundreds of meters away and explained.

"Don't worry, the root system of this tree can only absorb corpses that cannot move. It has no ability to damage moving objects. Nothing can easily break free from the constraints of the root system. However, don't get close to the radius of fifty meters around the big tree..."

...

From Opp's mouth, Zou Zichuan once again confirmed that those big trees are fearsome predators, even humans, are the recipes on its menu.

The three of them walked back again, their purpose was a satellite city next to the capital of the Gallen Empire. The satellite city was guarded by Opp's tribe and was responsible for resisting the invasion of the three southern countries.

"Brother Zichuan, I think you are very strong, why not sign up with me to join the army?" Along the way, Opp no ​​longer had the initial fear of Zou Zichuan, but encouraged Zou Zichuan to join the imperial army. Of course, Opp's heart was that he hoped to join the army with Zou Zichuan and take care of each other.
