A few months later. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Under the support of nearly 100 warships, Yuan Haochen flew towards the Green Hill Star on the command ship, and was about to enter the outer space of the planet in the blink of an eye.

[Welcome, friends from afar, powerful human civilization. 】

The Green Hill civilization sent greetings at the right time when the human fleet was approaching.

(Thank you for your hospitality.) As agreed, our fleet will stay in the outer space of the planet. ）

The human fleet also responded politely, and according to the previous agreement, only 6 spaceships were arranged to land on the planet Green Hill.

After receiving the exploration consultation sent back by the reconnaissance fleet, Yuan Haochen organized the high-level of the expeditionary force to communicate with the Green Hill civilization, and the whole process was very smooth. After initially figuring out the scientific and technological strength of the Green Hill civilization, the expeditionary force agreed with them on the time of visit and the landing location, and even the expeditionary force's escort fleet entered the star system, and even entered the outer space of the Green Hill Star, the other party gladly accepted.

All this really surprised Yuan Haochen and others. I am also looking forward to communicating with the Green Hill civilization in the future.

【Welcome to Green Hill Star!】 The other party quickly responded.

"Leader, you're ready, do you want to land on Green Hill Star immediately?"

Hallelujah, the deputy military commander in charge of the escort of the operation, asked for instructions.

"Let's land and let's see for ourselves this beautiful planet with green fields." Yuan Haochen nodded solemnly and said.

"Yes!"

......

A total of six spaceships and warships began to roar through the atmosphere of Green Hill.

The atmospheric conditions of the Green Hill Star are slightly different from Yuan Chen's expectations, he originally thought that with so many green plants and such a superior ecological environment, the oxygen content in the atmosphere should be quite high, but he didn't want to think that the actual situation was not the case. The oxygen content in the atmosphere of Green Hill is comparable to that of the planet Gaia, and even slightly lower than that of the former Earth.

"There must be a reason for that. Perhaps the oxygen content in the atmosphere of Green Hill Star was originally low, and it is still rising. Yuan Haochen quickly came to a relatively reasonable conclusion, "The green of this world is not like this from the beginning......

"After analysis, the composition of the planet's atmosphere is as follows: nitrogen 63.2%, oxygen 18.9%, carbon dioxide 7.9%, argon 2.4% ......"

What is quite rare is that the atmosphere of Green Hill Star is very suitable for human direct breathing, and the large number of green plants makes the air appear exceptionally fresh.

"Tut-tut, it's like it's tailor-made for humans."

"It's kind of unbelievable that there is such a coincidence in the universe......"

The scientists involved in the action sighed.

The Green Hill Star is two times smaller than the Earth, with a mass of only one-third that of the Earth. According to calculations, the gravity level of Green Hill is only about 72% of that of Planet Gaia, so humans should be quite comfortable moving on Green Hill.

The location where the human spacecraft landed was in an open and vast grassland near the equatorial region in the southern hemisphere of Green Hill.

Of course, this is also agreed with the Green Hill Civilization in advance. At this time, a large number of intelligent creatures of the Green Hill civilization are gathering around the grassland, preparing to welcome the arrival of human civilization.

The reason why Yuan Haochen and other high-ranking members of the expeditionary force finally decided to contact the Green Hill civilization was mainly based on the following considerations:

First, human civilization is about to go to the black hole Cygnus X-1, and the closer you get to the black hole, the more likely you are to come into contact with other cosmic civilizations. Therefore, at this stage, the expeditionary force urgently needs to have an in-depth understanding of the cosmic social system of this star field, and accumulate experience in contact and communication with other cosmic civilizations. Compared to a certain high-level cosmic civilization, contact with the Green Hill civilization in front of you is obviously the safest option.

Second, judging from the current performance of the Green Hill civilization, this is a kind and peaceful civilization. Although their level of science and technology is not high, their attitude and communication methods towards other foreign civilizations are quite extraordinary.

Third, why is the Green Hill civilization not afraid of risks and desperately seeking to communicate with other civilizations in the unknown universe? How exactly did they discover the expeditionary force's Phantom reconnaissance fleet? These questions have greatly aroused the curiosity of the human expeditionary force.

Fourth, the expeditionary force has already carried out a comprehensive evaluation and exploration of the entire star system, and ensured that the trip was safe.

......

"Boom !!"

The surging engines of the human spacecraft continued to compress and bombard the surface air of the Green Hill planet, making a sound that overwhelmed the mountains and seas.

However, in the face of the shocking scene in front of them, the intelligent creatures of the Green Hill civilization, which is relatively backward in science and technology, seem to be very calm, as if they have long been accustomed to all kinds of big scenes.

"It's really funny."

Looking through the porthole, the natural scenery outside and the orderly and intelligent creatures of the Green Hill civilization are all in full view.

"They're so different compared to the Sand Stars."

Yuan Haochen remembered the scene when the Sand Star people first saw the Future spaceship, and compared to the two, it was simply a heaven and an underground.

"Woo~Woo~Woo~"

After a buzzing sound, six spacecraft landed smoothly on the surface of Green Hill.

"The local temperature is 28 degrees Celsius, the environment is good, there are no toxic radioactive substances, and it is recommended to wear simple protective clothing."

"Everything is ready, whether to open the hatch or not, please indicate."

"Open the hatch!"

"Buzz~Buzz~Buzz~"

The first to open the hatch was the command ship at the front, and under the escort of several burly warriors, Yuan Haochen took vigorous steps and stepped on the surface of the Green Hill Star.

A strange, never-before-seen greenery, unfamiliar but not abrupt.

The air is warm, the feet are very soft to the touch, and the face is a gentle breeze.

"Babbling ~ babbling ~ babbling ~ babbling ~"

"Babble~Babble~Babble~Babble~"

The moment Yuan Haochen and the others appeared, a long and distant voice came from not far away.

It was the "chanting" of a large number of creatures of the Green Hill Civilization together, and the members of the expeditionary force had experienced this chant in the cosmic radio signal sent by the Green Hill Civilization that they had received earlier.

Although Yuan Haochen didn't understand what they were "singing" at all, he witnessed the orderly formation of Green Hill Civilization creatures, and heard the waves like waves in the distance, a strong sense of ceremony, a solemn atmosphere, and a peaceful atmosphere quickly infected everyone.

"Babbling ~ babbling ~ babbling ~ babbling ~"

"Babble~Babble~Babble~Babble~"

In the midst of the chanting, a phalanx of creatures of the Green Hill civilization slowly approached the command ship in a characteristic vehicle......
