"Shan'er, don't look at it, come over and eat!" The soft voice of a mother floats by, which can melt the frost of 10,000 years.

"Got it, you won't starve to death if you eat late." Yang Dan gently closed the "Solar System Disaster Record", and his words were endowed with the impatience that young people should have.

Yang Dan (Shan), born in 2082, is 21 years old in his youth, 175cm tall, weighs 55 kg, slightly thin, his face is pale, and his morbid expression is exposed all the time, and his physique is inevitably far inferior to normal people of the same age.

In his memory, there is no father's love, since he was born in this dungeon, he and his mother Zhao Feiying have relied on each other for their lives, and have survived in a small two-bedroom bungalow for 21 years.

Gently put the "Solar System Disaster Notes" back on the desk, slowly stood up, withdrew his eyes from the extremely bleak streets and alleys, and turned to leave the room to eat.

At this moment, a middle-aged woman in the living room with obvious wrinkles at the corners of her eyes was busy placing them on the dining table in the living room with the coarse tea and light rice.

Zhao Feiying's motherly state is always there, and the smile on her face is always better than a flower, but Yang Dan knows that she was once a great female soldier and a flower in the army.

As the saying goes, time can take away everything from people, and this is vividly reflected in Zhao Feiying.

Her beautiful face has passed with time, and the Zou Wen on her face and hands is the trace of time, which is the most powerful ironclad evidence.

Now she is just an ordinary and great mother, nothing more than .......

"Hehehe, look, this is your favorite original ecological vegetable, you must eat to your heart today." Zhao Feiying greeted Yang Dan with a smile.

Yang Dan's face was grateful, but he was a little withdrawn and not good at communicating.

When he came to the table and sat down, Zhao Feiying had already helped him serve the meal, feeling full of maternal love.

White rice, one of the scientific and technological products, is cooked from synthetic rice; There are two plates of fish and meat on the table, but they are also synthetic, and they are all food for people to quench their hunger.

Looking at the dining table, there is nothing more luxurious than the small plate of green vegetables, because it is the original ecological green food, and the smell of coal without science and technology is mixed.

In this dungeon where it is dusk at all times, having a plate of original vegetables for dinner is the result of Zhao Feiying's struggle for several months, so Yang Dan was moved to tears in his heart.

Zhao Feiying kept giving Yang Dan vegetables, but she was reluctant to taste them, if he hadn't been noisy and had to eat with her, she really wouldn't have been able to eat it.

Seeing that her son was sensible and filial, Zhao Feiying felt incomparably relieved and felt that no matter how much she paid, it was still worth it.

"After eating, let's pack our bags and leave the dungeon tomorrow to go to the Beiheng Underground Shelter. Time is running out, and in a month the Earth will hit the sun, so we need to set out early to evacuate. Zhao Feiying chewed on the food and whispered seriously with a serious face.

When it came to the evacuation, Yang Dan's eyes couldn't help but show a little resentment.

"Alas...... The number of spaceships is far from enough, and only the able-bodied people can be taken first, which is the instruction of the 'World Union War Committee', and for the sake of the continuation of mankind, the 'World Union War Committee' has to sacrifice some people. Zhao Feiying sighed deeply.

"With your father's contributions, it's still not enough to get two tickets?" Yang Shan lowered his head and gritted his teeth in retort.

Zhao Feiying sighed lightly again, and then showed a bright smile: "Don't worry, as long as we enter the Beiheng underground shelter, the probability of survival is 50%, and our chances of survival are still very good." ”

"If you can get on a spaceship, the chance of surviving is 95%." Yang Dan, who was a little rebellious, couldn't help but refute again.

"Hehehe, okay, don't think so much, eat well, the dishes are cold." Zhao Feiying chuckled heartily and used her kind love to soothe Yang Dan's negative emotions.

Yang Shan nodded, no longer stubborn about the hatred in his heart.

Now that everything has become a fact, they cannot escape the fate of being abandoned, they can't solve the problem, and only by being strong can they have hope of living.

After the meal, Yang Shan went directly back to the room to pack up his things, so as to be ready to leave at any time; Zhao Feiying washed the dishes and chopsticks and put them away, and also went back to her room to pack her luggage.

There are no four seasons of day and night in the dungeon world, only the unchanged dusk, and the passage of time is only presented by the wall clock on the wall.

In the process of packing his luggage, an iron box that had been sealed in the dust for 5 years attracted him deeply.

Five years ago, I remember it was May 12th.

At this unforgettable noon, the arrival of a team of soldiers shattered the expectation and disillusionment in Yang Dan's heart, and at the same time made Zhao Feiying feel that his collapsed soul was scattered.

"It's a pity that the space warrior ZG-D36-136 Yang Qiguo died in the solar exploration, this is a relic left by Yang Martyr, please take it. In addition, according to the 'Law on the Care of the Families of Aerospace Martyrs', you can receive sufficient daily necessities every month, this is a material claim card, please be sure to take it well, don't lose it. ”

These were the words of the military captain, and every word struck the most fragile hesitation in the depths of Yang Dan's soul.

Zhao Feiying is right, his father, who he has never seen, is a hero, and the world may forget it, but in his mind, it is an inextinguishable light.

However, this light could never appear in front of him, and his expectations became unattainable luxury.

Since then, Zhao Feiying has gradually lowered her profile, slowly turning from a fierce female warrior to a housewife who supports her family.

She left the heroic dream in her heart behind, because she didn't want to be in danger again, so as not to die of an accident, and finally leave Yang alone to face the world. Therefore, she endured the pain in her heart and tried to be a competent mother to fill the lack of fatherly love in Yang Dan's heart.

Yang Shan remembered that the iron box contained an iron vest, a high-grade thermostatic suit called the 'Cosmic Suit'.

According to historical records, since the outbreak of the cataclysm, after the appearance of the dungeon, the temperature on the surface of the earth has been below -80 degrees, and if humans leave the dungeon and go to the surface without preparation, they will freeze to death instantly.

As a result, high-tech clothes with constant temperature came into being.

And because every time people go to the ground, it is a life challenge again and again, so people call this kind of thermostatic clothing a thermostatic suit.

With the passage of time, the constant temperature suit has also changed several times, so there is a distinction between high and low; The difference is mainly reflected in the performance, the more advanced the thermostat, the more powerful it is.

He didn't want to use it, and if he could stay in the dungeon safely for a long time, he would rather abandon the reverie of an adventure on the ground than wear it on himself, after all, it was the only relic his father had left behind.

But it was destined to backfire, and tomorrow he had to leave the dungeon, and he had to put it on, and he had to learn to manipulate it.

He is no stranger to the use of thermostats, and it can be said that every young person in the dungeon is familiar with most survival technology products, because this is a compulsory course for the new generation, and those who have been students can actually operate all kinds of survival technology products.

Therefore, he only needs to familiarize himself with this cosmic battle suit to learn how it operates.......
