Mars, a satellite city of Phobos.

The first detachment of the Mars Fleet, which roamed the asteroid belt for more than a month, finally returned to Mars.

At this time, the Phobos satellite city is no longer the big potato shape it used to be.

Directly expanding to 92.7 kilometers in diameter, it is like a mechanical planet, with the metallic texture of industry and the cold mechanical feeling of cyberpunk, and still can't help but praise science.

On the fleet's special spaceport, Luo Feng, dressed in a space combat suit, floated down the traffic pipe and, with the help of nanorobots, headed for the interior of the satellite city.

The satellite city of Phobos includes the inner and outer cities, the annex city, and the four spaceports are one of the annexed cities.

Fang Shengliang, who was stationed in the satellite city of Phobos, was in the reception hall of the port, and when he saw Luo Feng and the others, he hurriedly floated over.

"Commander Luo, welcome back to Hong Kong." Fang Shengliang saluted and smiled.

Luo Feng shook his head and patted him on the shoulder: "You kid can't wait for me to come back!" ”

"Haha!"

The group floated towards the Mars Fleet's station, and Fang Shengliang reported some recent internal affairs and the situation in the universe by the way.

"Reaper civilization, insect ......" Luo Feng was in a slightly heavy mood.

Fang Shengliang also said in a deep voice: "As we step into the era of the Great Universe, such things may become more and more frequent. ”

Hey? Luo Feng felt that something was wrong with his body, as an elite warrior, his control over his body was meticulous, and he would notice the slightest change inside and outside his body.

He felt the gravity on his body gradually increase.

Looking at Luo Feng with a strange face, Fang Shengliang smiled and said, "Do you feel that your body has become heavier?" ”

Luo Feng reacted immediately and blurted out: "Artificial gravity?"

"Exactly." Fang Shengliang nodded, and then explained: "Half a month ago, the scientific committee sent someone to install it, and it was officially put into use three days ago. ”

They are in the outer city at this time, and the gravity is only 1~10%, and if they don't pay special attention, it won't be too obvious.

After floating for a while, they came to the junction of the outer city and the inner city, and went to the passage gate of the inner city, which was displaying [10%~50% of the quasi-gravity area, please pay attention to the gravitational effect. ］

"Let's go! Take you to feel the powerful embrace of Mother Blue Star. Fang Shengliang stretched out his hand to the gate.

Luo Feng passed through the gate without hesitation, followed by Xiao Bing, Zhou Yuan and others.

After entering the gate, there is not a direct passage, but an elevator.

Ding dong!

The elevator door is automatically opened, and on the exit gate, there is a display screen [50%~100% of the quasi-gravity area, please pay attention to the gravity effect. ］

At this time, Luo Feng and the others finally felt an obvious change in gravity.

"The 50%~100% anti-gravity zone is the area set in the black hole gravity furnace with a thickness of 10 kilometers, and the thickness of the bottom kilometer is exactly the same as that of the blue star." Fang Shengliang explained.

"I can't wait to feel the powerful embrace of Mother Blue Star." After Luo Feng finished speaking, he walked down the layers below.

This is the inner city, which is divided into 10 floors according to the gravity level, and at the bottom of the inner city is the core area of the black hole gravity furnace.

The Mars Fleet's resident headquarters was on the 8th floor of the inner city, and Luo Feng did not go back to the headquarters first, but went straight to the 1st floor of the inner city.

Stepping into the area on the first floor, Luo Feng was shocked for the first time.

The scenery that catches their eyes is not the cold metallic texture that they find boring, but the lush rural countryside.

The core radius of the black hole gravity furnace is 3.5 km, while the 1G gravity limit is around 3.9 km.

The 1st floor of the inner city was built on a radius of 3.9 kilometers and had a surface area of 200 square kilometers.

Robots and engineers are designing the layout inside, with a sanatorium, dormitories, parks, and an ecosphere, all on the first floor.

The dormitories and sanatoriums have been completed, and a large number of animals and plants are needed to enter, and now most of the natural environment that Luo Feng sees is actually holographic projections.

Only a slice of tomato, watermelon, and cucumber is a real plant.

Fang Shengliang, who took a deep breath, turned his head to Luo Feng and said, "The seedling cabin of the Life Science Group is already breeding plants and insects, and the cloning cabin is also cloning some animals, and soon this place will be full of life. ”

Luo Feng, who was lying on the ground, looked at the ceiling, above which was a "sun", and there was a blue sky and white clouds running.

The "sun" is a special light bulb that mimics sunlight, and the intensity and frequency range of light waves emitted by the bulb are not much different from those of the real sun.

The blue sky and white clouds are naturally holographic virtual images, with the ceiling about 800 meters from the ground, and the functions of airflow, temperature, humidity, rain and snow are set on it.

A breeze blew on Luo Feng's face, and he closed his eyes to feel this wonderful environment, which was completely different from the cramped and oppressive spaceship, as if he had returned to the blue star.

Human beings' innate attachment to the blue star made Luo Feng and the others immersed themselves in this moment, and their whole hearts were cheering.

Many fighters even have the urge to burst into tears, and have been adrift in the universe for more than a year, despite the presence of biocomputers and cellular robots to regulate their bodies, but many fighters' minds are full of depression and exhaustion.

Gravity and the natural environment are still an indispensable part of human civilization, and living in outer space for a long time is very prone to depression and mental illness.

Luo Feng and the others seemed to have received the baptism of nature, and their mental outlook had a sense of refreshment.

Fang Sheng on the side smiled brightly and said nothing, he felt this way before.

More than two hours later.

Luo Feng reluctantly took the elevator, returned to the headquarters on the 8th floor, and looked through the important documents that had been backlogged for more than a month.

Hey? Restart the R&D program for energy siphon devices?

"Isn't the research of loud, energy siphon devices banned? Why did it reboot again?"

Fang Shengliang on the side explained: "The scientific committee seems to have developed a solution that can solve the vacuum decay, so the research on the energy siphon device has been restarted. ”

"Really?" Luo Feng also asked casually, and then he turned his attention to the situation of the black hole bomb and other weapons.

Browsing through the internal documents, through which Luo Feng clarified the current level of warfare of the new human race.

It should be more powerful than ordinary low-level civilizations, with black hole bombs, neutrino star bombs, high-energy laser cannons, large electromagnetic cannons, and degenerate materials.

However, communication technology and faster-than-light flight technology are still a huge limitation, and it is not easy for new humans to break away from the ranks of insects and enter the ranks of reapers.

It's just that the recent waves of crises have made the new human society a little upset.

Luo Feng put down the file with a headache and felt the 0.6G gravity inside the 8th layer.

Suddenly, Fang Shengliang stood up: "Commander Luo, let's eat!" ”

Luo Feng, who was stunned for a moment, then nodded: "Okay." ”

The two of them walked together and came to the second floor with a gravity of 0.90~0.95, and at this time, many engineers, warriors, and researchers working at Phobos were eating in the restaurant here.

The gravity here is not much different from that of Blue Star, and you can also eat like Blue Star.

Luo Feng and the others directly ordered a spicy hot pot, a table of mutton rolls, steak, vegetables and enoki mushrooms, and a dark beer.

This long-lost way of eating, everyone happily feasted.
