After dealing with these folk matters, Yu Yifeng finally returned to business......

The dead are gone, the living will continue to live, and human beings will not stop developing because of grief. Ｘ

Scientific and industrial matters must continue, and mining is still the top priority.

Over the course of a month, the flight base docked above the Noah continued to fall. According to the plan laid down at the meeting, a new mining base will be built in the Arctic region of the Nix Star.

Of course, this time everyone has learned to behave, and the engineers will first have to put a lot of effort into checking the ground below for underground cavities.

Humanity doesn't want to be busy in vain.

After a month of hard work, the final answer was finally obtained: people used a drill bit similar to oil drilling, and drilled down to a depth of more than 10,000 meters, and no signs of underground cavities were found. In other words, this land is a real solid body, and there is no possibility of any landslide!

Theoretically, too, the Arctic has weak geological activity, no volcanoes, and no geothermal heat, so it is impossible for those black bugs to reproduce underground, and they do not burrow.

Now, humans can finally mine in the Arctic with peace of mind......

Although the temperature in this ghost place is too low, the temperature is more than minus 200 degrees all year round. In this low temperature environment, the mechanical failure rate has been greatly increased, and people have to add some maintenance factories......

However, there are many mines, so it is safe!

The original extinct volcano base was largely abandoned, excavators were no longer mining, and the factories simply transported the final processed metal products to the North Pole by airship.

Immediately afterwards, a packed flight base took off again, carrying a large number of surface workers to work in the Arctic region.

This is all good news......

Busy work, coupled with the fast pace of life, gradually washed away the sadness in people's hearts, and the whole society returned to calm and started a new life.

Humans are a fickle species in their own right, and time can dilute everything. Especially when the lifespan of human beings is only more than a hundred years, any grief can be soothed with time.

Immediately, a month later, the news of the Nyx Star native lizard was finally reported, which triggered a wave of discussion.

Everyone seemed to have encountered the most interesting things and talked about the indigenous people and the various underground ecosystems with a feverish face!

This is the first time that humans have come into close contact with extraterrestrial intelligent creatures!

The new human civilization will send a diplomatic team to conduct "peaceful and friendly" diplomatic communication with the indigenous lizards.

When the expedition team departs...... Just today!

"Are you all ready?" On the surface of the Nix Star, Yu Yifeng asked loudly, looking at the heavily armed people, his heart was filled with a trace of excitement.

"Ready!"

Everyone's voices are excited, apprehensive, uneasy, and longing, all mixed together and merged into a thick exploration**!

"So...... Let's go! ”

Yu Yifeng was dressed in modified power armor, and with a wave of his right hand, he took the lead in jumping into the cave.

There were more than 40 people in total, and in addition to the original eight soldiers, there were also a large number of biologists, sociologists, geographers, doctors, journalists, and so on.

They will be accompanied by a comprehensive investigation of the underground.

Of course, the rest are all heavily armed soldiers!

After all, there are dangerous creatures underground, and there may be an unknown civilization......

People also brought with them a variety of daily necessities and trading goods.

The load capacity of the power armor is very strong, and there is no need to worry about the load-bearing aspect at all, and the load-bearing materials of more than forty people can make people live underground for a long time.

The original plexiglass helmet has also been replaced by another nano-synthetic material.

Although the physical properties of this material such as impact resistance are not as good as those of the original plexiglass, the level of acid resistance and corrosion resistance is greatly improved, and there is no need to worry about being easily corroded by black insects.

Coupled with the fact that humans synthesize special agents based on indigenous herbs, the likelihood of black bug infestation is greatly reduced.

Along the way, nothing special happened, and the team moved forward in an orderly manner. Except for a few scientists who had never been in a burrow, everyone else was relatively indifferent.

Compared to the indigenous intelligent civilization and the hidden unknown civilization, these underground creatures are much less attractive.

Finally, after a three-day long journey, the approximate location of the indigenous village was found......

"Captain! Signal, signal appeared! The cell phone signal ......," an electronic communications expert suddenly exclaimed in surprise.

These caves are full of twists and turns, and the eight soldiers have long been unable to remember the specific road, only a vague memory. Therefore, it is very difficult to find the indigenous villages, and people can only find a general direction to walk.

However, when the soldiers left, they gave the indigenous lizard a mobile phone, which could send location signals. Now the communication devices carried by the army can be connected to mobile phones, which means that people are very close to the indigenous villages!

"Can you find the source?" Yu Yifeng's heart moved slightly, and he still asked calmly.

"Right over here, this position." The specialist pointed in the direction of a cave.

After an hour of walking, the temperature in the ground began to rise rapidly, reaching twenty-eight degrees Celsius and approaching thirty degrees Celsius. People suddenly felt a burst of red fire and a black swarm of insects, which was the magma of the underground crater!

"Found a place, this is the crater area! It should be here, in the direction of the indigenous village. One of the soldiers shouted excitedly.

Everyone swallowed in unison, their hearts began to beat faster, and one by one they became ready to fight.

At this moment, even the most indifferent people can't be indifferent, and people are a little nervous, apprehensive, and curious...... There are all kinds of emotions.

Yu Yifeng squatted down, and suddenly saw the triangular fork footprints of a lizardman.

"Wu Hao, Leo, a few of you come to the front, they may know you. And also...... No one is allowed to shoot or shout without my permission, understand!"

"Understood!"

The discipline of this team is still relatively strong. For such a dangerous and important task, it is impossible for a free and loose person to be chosen.

The crowd lightly turned two more corners, and suddenly saw a vine-like rope placed on the ground, most of which was buried in the earth, and the ground here seemed to have been excavated.

"Be careful, it's their trap, there will be a trap at every junction leading to the village!" Wu Hao hurriedly said first.

He carefully circumvented the trap, crouched down and pulled the rope so hard that the ground collapsed in one fell swoop.

"Huh?"

A few lizards popped out of their heads.

When they heard the noise, they thought they had caught some prey, and they quickly ran in from the opposite hole, and they were stunned when they saw the tall power armor of the humans.

The lizards were so frightened that it took a few seconds to realize that they had not fallen into the trap, and they ran back frantically, shouting, "Ahama, it's time for him!" ”

"Ahamah, he should be!"

"It's alive!"

"There really are words!"

Many biologists see real lizardfolk for the first time, and they are extremely agitated. Their eyes collectively glowed like wolves, as if they had seen flesh and bones after three days of hunger......

However, without Yu Yifeng's order, no one acted rashly, just stayed where they were.

"Wu Hao, they don't seem to know you anymore!" There are also whispers of discussion.

“…… Maybe it's not the same group of lizards. There must be more than one of their leaders, right? ”

According to the simple translation of the human version, "Ahama should have been! It means "there is an enemy, danger", and when the lizards saw the humans, they ran back to report the news.

At this time, the strongest group of lizards will run out to fight and guard their village.

Sure enough, in less than three minutes, a large group of lizards appeared in front of people...... r
