The two women opened the door and walked in, the door was closed again, inside is a living room with a large area, the living room is connected to the kitchen, the living room is also the dining room where they eat, next to the kitchen is the storage room, the storage room is stored in a large amount of food and other materials, the storage room is convenient is the bathroom.

Three rooms, one room is a room shared by thirteen children and two women, there are no beds in it, but bunks on the floor, in order to keep warm, Dong Yanfei and Tian Fangfang also built a fireplace, the smoke pipe of the fireplace was led to the ground by them, and it was not facing up, after all, if it leads to the outside, the smoke is easy to attract the attention of people with intentions, or those mutant monsters, and then their underground base will be in danger.

The other two rooms, one for the two women's research and the other for their small plantation, yes, the underground base was small, but they built a research room and a plantation.

The research room is naturally two women in order to study the cause of the apocalypse, or to study the P virus, as well as the aura effect in the air, as for the plantation, the two women are to test whether they can grow some mushrooms and seaweed, both of which can grow in such an environment, and it can be said that these two plants are also the best plants in all bases on the blue star now.

If Dong Yanfei, a highly talented student of Beijing University, is a scholar and a middle school bully, then Tian Fangfang is a very rare genius in the history of mankind, in the normal society before the apocalypse, in order not to attract the attention of people with intentions, or the attention of the country, she behaved like an ordinary scholar, and the university was studied in Shenzhen University, but only Dong Yanfei knew how terrifying her sister's IQ was, and it was only an insignificant reflection of her IQ.

After the outbreak of the apocalypse, Tian Fangfang also became an evolutionary, but her evolution ability is not the ability to control metal, earth elements and the like, her evolution ability is the evolution of the brain domain, yes, it is her brain evolution, which makes her IQ even more terrifying.

It was with Tian Fangfang's plan that they were able to build such a hidden and safe base.

Concubine Dong opened the door of one of the rooms, and the children inside heard the sound of the door opening, and as soon as they saw Concubine Dong Yanfei's figure, the children in thick clothes gathered around one after another, chattering non-stop.

"Sister, you're back."

"Sister, are you in any danger?"

"Sister, I miss you."

"Sister, I want you to take me to sleep."

Thirteen children, the eldest is ten years old, and the youngest is only four years old, but because they are all orphans, they are more sensible in themselves, and now that the world has entered the end of the world, they have become more sensible, even if they have to stay in the underground base every day and see the light of day, but none of the children have a voice of complaining, and they will also worry about Sister Dong Yanfei, who goes out on adventures every day.

"Okay, sister is fine, sister will take you to sleep."

As long as she sees the children, the smile on Dong Yanfei's face is extraordinarily beautiful, and only these children are the biggest motivation for her to go out every day to face those mutated monsters.

"yes, let's all go to bed."

Tian Fangfang also urged the children to sleep on the side, after all, it was warmer to get into the quilt, otherwise even if there was firewood burning in the fireplace in the room, the temperature in the room was still more than minus 30 degrees, and for the children, the temperature was still relatively low.

Hearing the words of the two sisters, the children obediently got into the bed, they did not take off their clothes, in fact, they did not need to take off their clothes, although it was a little uncomfortable to sleep in thick clothes, but it was better to be warm than uncomfortable.

Concubine Dong and Concubine Dong watched the children sleep, and when the children were asleep, they left the room, they still had things to do, and they wouldn't go to bed until late.

The two came to the end of the corridor, there was an iron door at the end, opened the iron door, after the two entered, they closed the iron door again, and then through a passage about thirty meters long, they reached the end of the passage, and at the end of the wall was a ladder, and the two women climbed to the top along the ladder, and at the top was a round cover, the cover could be opened from the inside, and the two of them came out of the hole, and the outside was a very small room, and there were several shelves in the room, and various car parts and repair tools were placed on the shelves.

Just looking at the contents of the room, the average person can guess what this place is, yes, this is a car repair shop not far from the orphanage, and secretly this shop is also a well-known modification shop in the city.

The two women opened the door of the storage room and came outside, there was a corridor outside, the corridor seemed very dark and quiet, both women were evolutionaries, they could naturally see clearly, they passed through the corridor, and came to the maintenance workshop outside, the maintenance workshop area is not small, there are several cars parked there, the most conspicuous of which is a Scania Hagrid RV.

This RV is 13.7 meters long, 2.55 meters wide and 3.8 meters high, which can be said to be similar to ordinary buses.

Yes, the RV was modified, and if it was before the apocalypse, such a car would not have been on the road at all, but there would have been no sheriff to inspect it in the apocalypse.

Although the underground base of the orphanage is very safe, and there is no shortage of food and water, Tian Fangfang and the two daughters are still ready to retreat, and this RV was modified by the two of them in the past ten days.

The original tires can't walk on snowy roads, and many things in the entire RV have been remodeled, it is precisely because of Tian Fangfang's super IQ and knowledge, as well as Dong Yanfei's ability to control metal, that they can modify this RV, otherwise it is impossible for one person to successfully modify it, it can be said that the abilities of the two are highly complementary.

Open the car door, the two walked up, Tian Fangfang turned on the lights inside the RV, the overall decoration of the RV is very luxurious, there is a feeling of splendor, this RV is a two-story structure, they came up is the first floor, but also the living room on the first floor.

The living room has a wrap-around sofa and a table that can be folded, and across from it is an open kitchen with appliances such as induction cooker, microwave, refrigerator, etc.

There is a cab on the first floor, which has three seats, and behind the seat is a small bed for one person to rest and sleep.

There are three bedrooms on the first floor, a bathroom, a storage room, go to the staircase on the second floor in the living room, two people go up to the second floor, there are only four rooms on the second floor, and there are no other settings, each bedroom can live four people, a total of seven bedrooms, you can live twenty-one people, and it is also an adult, if it is a child, it can live fifty.

I don't know which local tyrant bought this RV before the end of the day, at least 10 million, but now it belongs to Tian Fangfang and the two daughters, and they spent more than ten days modifying this RV and transforming it into an RV that can drive in extremely cold temperatures and thick snow.

Dong Yanfei's ability to control metal is very peculiar, she can change the atomic and molecular structure inside the metal, and can turn an ordinary metal into a special metal, which is also Tian Fangfang's confidence that she can transform this RV into a snowmobile that can drive in the snow on the wandering earth.

The two girls worked for an hour to finish what they had to do today, and in two days the RV would be completely transformed.

The two women did not immediately go back to the underground base, but sat down on the sofa in the living room on the first floor to chat.
