The shuttle that Li Chuan and others rode successfully entered the planet's atmosphere at the angle of attack. In addition to him and three other members, the shuttle that landed also brought an artificial human armed force composed of a team of 7 people.

At this time, the shuttle was already on the high altitude atmosphere, with a vertical height of 53 kilometers from the surface land. Below was a thick and huge cloud layer, at least more than 6 million square kilometers, endless.

"Have the atmospheric components been analyzed?" Li Chuan asked in the work compartment inside the shuttle, looking at the display panel in front of him.

"It's out." Cock responded immediately, clicked three times on the control panel, and then said: "67% nitrogen, 25.6% oxygen... Argon and hydrogen were detected, wow, this place is like the earth."

"But you cannot breathe the local air directly, and the human body cannot be directly exposed to the local atmosphere..." Cock looked at the latest updated data and added: "The carbon dioxide component was detected, oh, it was true that the more beautiful the appearance, the more deadly murderous intent is hidden. No wonder there is no glacial landform on the surface of the planet. The volume fraction concentration of carbon dioxide in the planet's atmosphere is 5.93%. Humans will die after being exposed for 48 seconds."

Even in the Earth's atmosphere, where the "greenhouse effect" is significantly improved, the volume fraction of carbon dioxide in the air is only about 0.037%. The carbon dioxide component in the atmosphere here is simply outrageously high, and it is a paradise for plant life. If there are wheat here, the size of a grain can probably be as big as a person's thumb, but it is large but not refined, and the nutritional content is extremely low.

For humans, when the carbon dioxide content in the air reaches 1%, people will feel stuffy, dizzy, and palpitations; when the carbon dioxide content in the air reaches 4%-5%, people will feel headaches and dizziness. When the carbon dioxide volume fraction in the air reaches more than 6%, it will make people confused, breathing stops, and death.

This planet is not a beautiful paradise for humans.

"It's about to cross the clouds." Liu Jin was driving the spacecraft and reminding everyone in the communicator. Cock and others couldn't help but look at the round window. At this time, the outside of the aircraft was dark, accompanied by lightning and thunder.

A heavy rain is about to come clearly.

At this moment, the shuttle is flying over the supercontinent of the southern hemisphere, and the purpose of landing is to be located at the sea and land junction in the southwest of the continent.

More than ten minutes later, the shuttle successfully passed through the clouds, with an altitude of only 2,000 meters. Cock looked out through the circular window, and the direction of starboard was located, heavy rain began to begin to rise more than 30 kilometers away, accompanied by violent lightning and thunder.

At this time, the aircraft is flying supersonic and must complete the landing before the heavy rain falls.

Mountains, waterfalls, rivers, and especially green forests that are towering into the clouds, the plants on this planet are too lush, with towering trees a hundred meters high everywhere, and the Amazon rainforest on the earth must also feel inferior.

The shuttle quickly climbed over a mountain range. Liu Jin, who was controlling the aircraft, couldn't help but look down at the ground through the cabin window. There was a huge valley in his view. When he saw it, Liu Jin was stunned to see bursts of light spots bursts under the valley.

He immediately adjusted his flying posture and let the high-speed camera on the shuttle face towards the big valley. The clear picture was displayed on the screen after a moment. When Liu Jin saw it, his pupils suddenly shrank slightly.

"Everyone, you'd better come and have a look."

...

Between the valleys.

The sound of "squeaking" spreads throughout the valley, and only tens of thousands of reptile organisms gathered together, with an average length of about 3.7 meters. Their lower body is like snake organisms. Because they have no feet, they move by scaling their abdominal scales and muscles.

These tens of thousands of creatures of the same type are all gathered together, as well as an army, each standing upright, about 1.8 meters high, almost the same as humans.

Their upper body has two arms, four fingers, holding metal-constructed tools, or firearms with holes.

It's a weapon!

These creatures have no hair, but are made up of tiny dense scales, which are difficult to see without careful observation. The structure of their heads is fluid. Such biological structures are obviously suitable for moving in water because their tails have caudal fins at the ends, and the ears on the head can be stretched out with a slender ear, and the spine on the back also has small spinal fins. There is also a thin film between their fingers, which can be expanded when they are stretched out, just like duck feet, frogs or birds.

These traits all show that these creatures can live underwater, and they all show that they are amphibians.

At this moment, among the group of creatures, one suddenly held the equipment in his hand and pointed to the built trench above the valley.

It makes a "squeaking" sound, but humans cannot hear it directly because it emits high-frequency ultrasound waves similar to dolphins.

Suddenly, the tens of thousands of amphibians under the valley raised their tools in their hands, and the spinal fins on their backs suddenly stood up, and their ears spread out like fans.

Finally, the creatures under the valley charged forward, and these amphibians moved extremely fast, and only their abdominal scales and their muscle tissue could do this.

At the same time, there is a group of the same amphibians above the valley, but they are obviously not from the same group.

Above the valley, some serpentine amphibians ignited fire, and each of them held crossbows and hot weapons similar to muskets to attack the enemy soldiers rushing down. As the defense party, despite the small number, they occupied favorable terrain, causing heavy losses to the attacking party. If they did not make an inch, they would have to pay huge blood and casualties. Many attackers were hit by the stubborn stones thrown from the trenches and rolled down, but they could not stop the attackers from behind from launching a charge.

Just as the battle situation was getting hot here, a huge flying object suddenly whistled past the mountains above the sky. The roar of the engine exploded in the sky, slowly entering the valley, attracting the creatures under the valley to look up.

"Squeak squeak..."

The leader of the attacking side suddenly issued an order, and suddenly, these tens of thousands of amphibious creatures retreated like a tide.

Above the sky, Li Chuan and others stared at the captured images in the shuttle. Sara Sieg murmured as the plane crossed the valley: "This is war!"

The breath of barbarity, the bloody conflict...

"When you are smart, you will have desires. If you are eager, you will inevitably lead to disputes... Haha~" Li Chuan said to himself, and Liu Jin's voice sounded in the communicator: "It seems that the indigenous civilizations of this planet have just learned to use firearms, which is equivalent to the technological level of our human age of great navigation."

"At that time, humans didn't know what electromagnetic waves were, and they didn't even have a concept." Sara Sieg said firmly: "And the technological level of the indigenous civilization on this planet could not be even less than the level of the first industrial revolution."

"Isn't this the goal of this trip?" Liu Jin smiled. He was surprised by what happened under the valley because this was the first time that he had confirmed and witnessed a conflict between extraterrestrial civilizations.

When Liu Jin discovered the alien civilization, he was still surprised and even felt anxious. However, when he saw that the indigenous civilization on this planet was still in the era of cold weapons and a small number of firearms, he subconsciously breathed a sigh of relief, and he showed a relaxed mood in his own attitude as a high-level civilization. A hint of uneasiness in his heart disappeared, which he had never noticed.

The shuttle successfully landed in a dry and dry place with sparse plants and visible ground soil. This place has been 7,000 kilometers away from the valley.

It was correct for Li Chuan to unload a large box from the warehouse and prepare in advance. Under the control of the sensor in his brain, he put on black nano armor in a short while. At the same time, black fluid also rushed to other members to put on a set of people, and artificial humans also put on black armor.

Space suits are not combat suits, and this planet is no more than a wandering planet. It is now possible to confirm that there are indigenous civilizations. Although it seems that they are still in the age of cold weapons and have entered the age of firearms with half a foot, the level of danger is much higher than that of a wandering planet.

"I hope to treat the unknown, I will have a sense of awe..." Li Chuan, in the black armor, looked around everyone, "Anyway, pay attention to safety... open the cabin."
