Wang Luoxuan came to this world called Doom Day, and also obtained the temporary talent skill "Survivor".

Survivor (Temporary Gifted Skill): When you feel your life in danger, your adrenaline will rise dramatically, your speed and strength will be increased by more than half of your normal time, and your pain perception will be reduced.

Wang Luoxuan followed Zhang Qi into an abandoned subway station, and in the depths of that abandoned subway station was the entrance to the underground shelter.

In this abandoned subway station full of dust and cobwebs, under the illumination of lighting equipment, Wang Luoxuan saw many human skeletons, all of which maintained their movements at the last moment of their lives, and Wang Luoxuan could see that they were desperate.

"Do you know the story of this subway station? Zhang Qi used the firearm in his hand to remove the cobwebs in front of him, and suddenly asked Wang Luoxuan.

"You know what? ＂

"Of course. The place is one of the secret passages that connect to the underground shelter, but this passage was opened ten years ago, and the bones of this place are more than ten years old. The city was destroyed forty years ago at the hands of the xenomorph monster 'Tyrant', and the panicked people fled into the subway station, only to be trapped here. In the absence of food and water, there was a situation of cannibalism, and in the end, all those who survived by cannibalism died of disease. I must have been desperate to be trapped in this place for so long, until I died completely! This place was opened ten years ago, and the people who opened this place saw these stories in their diaries next to some bones. ＂

The timeline that Wang Luoxuan is in now is forty years after the outbreak of the Day of Destruction, and during these forty years, human beings have been underground, waiting for a chance to return to the surface.

Through a hole in the wall of a subway station, Wang Luoxuan and Zhang Qi entered a lifting platform, which descended rapidly, and the steel cables continued to sputter sparks due to friction. I don't know how long it took to descend, until the lifting platform reached the bottom, and Wang Luoxuan and Zhang Qi walked out of it.

At the exit of this lifting platform, a group of people wearing white protective clothing had been waiting for a long time, and when they saw Wang Luoxuan and the two coming down, they immediately picked up the spray gun in their hands and sprayed out the white smoke to disinfect Wang Luoxuan and Zhang Qi.

It wasn't until the disinfection was completed that Wang Luoxuan and Zhang Qi took off their protective clothing and respirators......

"Congratulations on your safe return to the Huaxia Tianji Underground Shelter! ＂

Wang Luoxuan and Zhang Qi didn't say much, but handed the recorder on their heads to those who were wearing white protective suits.

"Starting today, the two of you have obtained the civilian qualification, which is your civilian certificate. The leading guy took two cards and handed them to Wang Luoxuan and Zhang Qi.

"This qualifies as a civilian? Wang Luoxuan looked at the card with his photo printed in his hand and frowned.

"But if you two want to be qualified to survive in this underground shelter, you have to work hard, and the place of work has been arranged for you, so you will be on duty tomorrow! But it should be much safer than what you used to do. Now the two of you can go back and get some rest. ＂

"Hmmm! ＂

The two nodded and left the place, and when they walked out of the building, Wang Luoxuan also saw this Huaxia Tianjian underground shelter for the first time......

"! ＂

The place where people live is eight thousand meters underground, and Wang Luoxuan can see the rock wall above the sky when he looks up, and the entire underground has been hollowed out.

In the center of the Celestial Sanctuary is a tall tower, 2,333 meters high, only 500 meters away from the highest rock wall, and at the highest point of the tower radiates a sun-like light, illuminating the entire sanctuary. The tower, called the Tower of Dawn, controls the intensity of the light according to the change of the day, and it will be extinguished at night, and in general, in this underground world, the tower acts as the sun.

In the whole world, in addition to the Tiangong Shelter in Huaxia, there are large and small shelters for human beings all over the world, and there are three shelters of such a scale as the Tiangong Shelter in Huaxia.

Because it is an underground world, it is very densely populated, and there are nearly 100 million people living in a heavenly shelter, which is already quite terrifying. However, this underground shelter is also very large, and the current surface environment is not suitable for human life, so this underground shelter is still expanding.

There are some memories in Wang Luoxuan's mind, which are the memories that the funeral requiem gave him, and these memories tell him the basic common sense of living in this world and where he lives.

The sidewalk was unusually crowded, after all, in this underground shelter, the life of the people was too dense, and just walking on the sidewalk gave Wang Luoxuan a feeling of breathlessness. Naturally, there is a lane for vehicles in this shelter, but there are very few vehicles on top of it, and ordinary civilians are not allowed to own vehicles under the laws of this shelter. The vast majority of the traffic on the lanes are special vehicles such as ambulances.

The food and daily necessities of this world are all distributed, and are distributed evenly to each person and the worker's family according to the daily workload. In other words, money has no role in this world at all, and the entire shelter does not even have a store.

"It seems that it is a little difficult to make money in this world to exchange for soul points, and the people of this world already think that currency is history. Wang Luoxuan sighed deeply, this is not good news, originally he wanted to earn a little more soul points.

"Alert! Alert! The xenomorph monster 'Nine Scales' is coming! Please evacuate to the nearest safe zone! ＂

"Alert! Alert! The xenomorph monster 'Nine Scales' is coming! Please evacuate to the nearest safe zone! ＂

The sound of the alarm echoed throughout the shelter, and at this time Wang Luoxuan was a little confused, this is underground, how did those monsters come down?

The surrounding ground was opened, and there were hidden entrances to the underground safe zone, used to respond to special events in an emergency.

"Boom!! ＂

There was an explosion in the distance, and the crowded crowd became chaotic, and Wang Luoxuan even saw many people being trampled to death by the chaotic crowd.

There was a sound of propellers overhead, and Wang Luoxuan saw a large number of transport planes hoisting a giant mecha with a height of 100 meters, rushing towards the explosion site......

Wang Luoxuan looked up at everything, he was stunned for a while, and even forgot to take refuge, after all, driving that mecha is much more exciting than driving a tank......
