After looking at the alien base for a while, Shu Xin withdrew her gaze and set her eyes on the dazzling red number on the protective light curtain—37.

The shield opened by the aliens can not only block the attacks of radiation and mutated animals and plants, but also detect the current radiation level on the earth's surface.

The red number 37 means that the current radiation value on the surface is 37.

This number is not static, and with the change of time, the rise and fall of the sun, the surface radiation value will change.

Glancing at the somewhat torn E-class combat uniform on her body, Shu Xin frowned slightly.

The upper limit of the E-level combat suit is 100, that is, if the protective suit is not damaged, as long as the surface radiation does not exceed 100, she can walk freely outside without being affected by radiation.

If it is exceeded, the radiation will penetrate into her body, and once the radiation in her body reaches the upper limit that her body can bear, she will have various conditions such as weakened physique, lower health, and weakened force due to excessive radiation.

It's a pity that her E-class combat uniform is torn.

After fighting mutated animals and plants for a long time, the combat uniform will inevitably be damaged.

At the moment, her E-Tier combat suit stats are 50/100.

This means that if the suit is damaged, the amount of radiation it can block is reduced, from 100 to 50.

And, due to living in a dungeon where radiation can penetrate for a long time, the radiation level in her body has reached 40.

Although the upper limit of the body's tolerance has not yet been reached, you should also pay attention.

Radiation residues in the body are not a good thing.

Shu Xin no longer looks at the alien base, she has to hurry up, while the temperature is not very high, the mutant animals come out to activities, and earn some more experience points.

Experience is Star Coins.

If you want to survive, Star Coins are indispensable, whether it is nutrients and energy liquids that fill your stomach and replenish energy, or combat equipment, weapons, and medical items, you need to buy them with Star Coins.

Also, she had to quickly improve her physique.

Her body is too weak now.

Thinking of the news she heard by chance in her previous life, Shu Xin's eyes moved.

Mutant ginseng!

Maybe she should go and explore the medicinal herb base in her previous life that was only discovered a year later.

During the ten years she was imprisoned by aliens for experiments, she didn't find nothing.

If she could really find mutant ginseng, then she would have a way to extract ginseng essence that the human body can absorb quickly and has no weaker effect than the N1 dose of physique enhancement liquid.

After thinking about what to do, Shu Xin no longer hesitated, turned around, buried her head and walked towards the nearest danger zone.

Safe zones, dangerous zones, and no-man's land are the divisions of human beings according to the degree of danger after the digitization of the earth.

Like an alien base, it's a safe zone.

The dungeon outside the alien base is also half a safe zone.

The danger zone is a wide range, simply a place where humans can move, but these places are either mutated animals or mutated plants.

According to the degree of danger of mutated animals and plants, it is divided into low-risk area, medium-risk area and high-risk area.

As for the no-man's land, it is the place where people can't go, and if they go, they can't come back.

The people in the square above the dungeon saw Shu Xin going out alone, and they all cast surprised eyes.

"Who is this man? How dare you go to the danger zone alone? ”

"Whatever, maybe it's a big guy."

"How is that possible? I just saw her coming out of the dungeon, if it's really a big guy, how can she not live in an alien base? ”

"I guess what kind of stupid bold with brain problems!"

“......”

The reason why everyone was surprised that Shu Xin went out alone was mainly because the current earth was too dangerous.

The reason why the Earth has become dangerous is mainly due to the light rain that swept the entire Earth on May 20, 2500.

Light rain contains powerful radiation rays, which not only weaken the earth's magnetic field, but also change the genes of all living things on the earth, and cause devastating damage to the earth's ecosystem.

Then, the earth was digitized, and the end times followed.

Shu Xin still remembers the terrifyingly cold mechanical voice after the light and rain in the sky.

"The digitization of the earth begins!"

"The end of the digitization of the earth!"

In just two sentences, without preparing or choosing the earth, extraterrestrial civilizations forcibly invaded the earth.

Recalling the scene of that day, Shu Xin still feels extremely heavy.

Because the radiation contained in the light source is too powerful, many people either die of excessive radiation or become bloodthirsty monsters with serious violent tendencies due to genetic deterioration.

At the same time, because radiation penetrates the earth indiscriminately, not only the genes of humans but also plants and animals are changed.

Weak animals and plants are directly extinct, and animals and plants that have carried radiation are disasters for human beings.

Can you imagine an ant that has skyrocketed several times in size overnight because of a genetic mutation? One ant is not scary, but what about tens of thousands?

What kind of terrible scene is it that the originally harmless flowers and trees suddenly grow teeth and swallow an adult in one gulp, without even spitting out the bones?

......

Of course, there are also opportunities in crisis, and evolution and deterioration coexist.

The aliens also don't seem to think of the direct extermination of the human race on Earth.

Because of the genetic mutation, the human constitution has been enhanced, and the enhancement of the constitution has led to an increase in lifespan (provided that you can survive in a harsh environment), and the mental field of the brain has been unprecedentedly developed.

At the same time, aliens also bring alien civilizations and interstellar technology.

At the beginning of the apocalypse, because of the wisdom brain, alien mall, and 'kind' aliens (NPCs), coupled with the small number of genetically deteriorated mutated humanoid monsters, the sense of crisis of human beings was not very large, and I once thought it was a game.

It was not until later, when the mutated animals and plants continued to grow stronger and stronger, that more and more people died, and humans really realized that this was a real end times.

Shu Xin walked towards her goal at a rapid pace, while quickly recalling the scenes of the early days of the apocalypse buried deep in her memory.

Suddenly, Shu Xin stopped, frowning at the ruins in front of her that still retained some of the appearance of the pre-apocalyptic city.

Maybe it's because it's too close to the alien base in S City, and the alleys in the ruins are still intact.

This time, she left very early, but she didn't expect to run into someone.

At this moment, in the alley directly opposite her, a man in his 20s ran out in a hurry.

The man's face was tired, and after running into the alley, he sat down at the base of the wall, gasping for air.

Seeing this, Shu Xin paused slightly and continued to walk forward.

"Whew~"

"Whew~"

"Whew~"

Lin Yucheng panted and tugged at his neckline irritably.

Today he was really unlucky, in order to hunt some more mutant animals, he left the dungeon early in the morning, but he didn't expect to meet his rival Sun Kun and his men outside.

In order to catch him, Sun Kun chased him with his subordinates for a morning.

If it weren't for the fact that his strength was not as good as him, he was trying to teach him a hard lesson.

Lin Yucheng thought angrily, turned his head slightly, and saw a woman walking towards him.

The woman didn't look big, 20 years old, with a high ponytail, wearing a neat E-class combat uniform, the combat uniform should have not been changed for a long time, and he saw several broken places.

Not a strong one!

Lin Yucheng immediately made a judgment, if he was strong, not to mention changing the D-level combat uniform, he would not pass on such a shabby E-level combat uniform.

Soon, Lin Yucheng no longer paid attention to Shu Xin.

Without him, it seems that the people who are chasing him have come.

Shu Xin walked halfway up the alley, and several tall men ran into the alley opposite.

"Lin Yucheng, you turtle grandson, Lao Tzu finally caught you!"

Seeing that it was Sun Kun and they caught up, Lin Yucheng had an expression of wanting to plant, and as soon as he stood up, he was surrounded in the alley.

Looking at this scene, Shu Xin frowned and stopped.

She was not afraid of the man before, but the few who came later were obviously from a hunting group, although she was not afraid, but she didn't want to take the initiative to provoke a certain force.

She didn't want to provoke, but the other side didn't want to let her go.

"Yo, there's still someone!" Sun Kun glanced at Shu Xin with a smile, and sighed twice with an unknown meaning in his mouth, "It's so bold that I went out alone." ”

"Brother Kun, I know her, she is the one who won Zhao Lu in the ring yesterday, it seems that her name is Shu Xin."

Sun Kun looked at Shu Xin in surprise: "If you can win Zhao Lu, your strength is good, no wonder you dare to enter and exit the danger zone alone." ”

Zhao Lu is also well-known in the dungeon, and he has also heard about her fighting with people for a strange fruit.
