"Mom, go ahead. It''s cold outside." The expression on the doctor''s face suddenly froze, and he quickly pushed his mother back into the room.

    After pushing his mother away, "doctor" said to Xie Chang, "Xiao Xie, my mother is such a person. She has no malice. Don''t take it to heart!"

    Obviously, the "doctor" did not regard Xie Changzhen as a servant who ate and lived in their house.

    In the face of other people''s housework, Chen Xin didn''t say anything. He just picked up the "doctor" to exchange his medicine box, explained to the "doctor" how to use the oxygen generator, took another look at Xie Chang, and then turned to drive his car away.

    On the way home, Chen Xin recalled his mother''s attitude towards Xie Chang, and felt inexplicably uncomfortable.

    Although the "doctor" mother''s attitude towards Xie Chang even before the end of the world seems to be a common norm, Chen Xin just thinks it''s wrong.

    Because it lacks the most basic respect between people.

    At the end of the day, maybe everyone is struggling to survive. Some people do selfish things in order to survive.

    But Chen Xin always thinks that even if he damages the interests and even lives of others in order to survive, he should maintain the most basic respect for others.

    The reason why people are called human is that we have human nature and morality, which is the biggest feature that distinguishes us from wild animals.

    If man can''t be called man, what''s the difference between man and beast?

    What''s more, even wild animals don''t make fun of bullying, maltreating and insulting the same kind.

    This is something that can only be done when people lose the moral bottom line and the most basic respect for people.

    Chen Xin has no intention to evaluate the "doctor" mother''s attitude towards Xie Chang, but he never hopes to meet such a person who does not know how to respect others.

    Fortunately, the doctor''s mother lives in their own shelter. Otherwise, if it''s an official shelter, her attitude towards people is likely to cause trouble.

    If put in the doomsday environment of those films and TV works, I''m afraid she is the fastest group of people to die.

    Chen Xin shakes his head. He seems to think that it''s not good to curse people to death. So he doesn''t think about it any more. He steps on the accelerator and plans to go home as soon as possible to see if the medical box given by the doctor can be upgraded into a medical room.

    It seems that the roads in the urban area have also been cleaned up. Although not all the roads are unblocked, at least several main roads remain unblocked.

    Chen Xin''s car didn''t drive slowly and soon returned to his refuge.

    After some cleaning up, Chen Xin returned to the living room with his medical kit. He found out his medical kit and first aid kit and put them together.

    Looking at his three pieces of medical supplies, Chen Xin thought about it and then moved a chair.

    If it is upgraded to a medical room, the upgrade level will not be too high. There is no need to make a medical bed, but at least there should be a place where you can sit down and deal with the injury or treatment.

    After getting everything ready, Chen Xin hesitated for a moment and put everything in the corner of the living room. Instead of moving to the empty garage, he planned to connect the medical room with the living room.

    Chen Xin plans to build a studio there to make some equipment or other things.

    After all, if we want to build big things like power armor or machine armor in the future, we must need space, although it is still far away for Chen Xin.

    Everything is ready, Chen Xin calls out the upgrade interface of the system.

    "Simple medical disposal room"

    "upgrade scheme 1: expand the space of medical disposal room, increase the operation seats, upgrade the surgical instruments, increase the sterile space, the bacterial reproduction rate is - 10%, and the survival point required for upgrade is 1000"

    "upgrade scheme 2: expand the space of medical disposal room, increase the detection equipment, increase the drug storage cabinet, and the drug storage time is + 10%, and the survival point required for upgrade is 1000"

    "upgrade scheme 2: expand the space of medical disposal room, increase the detection equipment, and increase the drug Survival 1100 "

    seeing the upgrade plan given by the system, Chen Xin finally felt relieved.

    He had been worried all the time. Even with the medical box given by the "doctor", the system still didn''t think it was enough to make up a medical room. What should he do.

    If that is the case, he will have to go to the "doctor" or get some medical supplies through Qin LAN.

    Although it''s not a lot of trouble, Chen Xin doesn''t like such a toss.

    Fortunately, the system has given Chen Xin a satisfactory result. He just needs to upgrade.

    Chen Xin is not in a hurry to upgrade. Upgrading the medical disposal room will require some materials if it is not just for survival.

    There are some things he doesn''t have. He plans to go back to Qin LAN to exchange.

    Anyway, now that he has the frequency of the communication channel of the special police team, he can contact Qin LAN by himself, and he doesn''t need to pass another message through Mo Qingyan.The result of being able to upgrade the medical room made Chen Xin feel in a good mood. It happened to be lunch time again. He decided to have something good today.

    From the storage room, he took out a can of pork and a shelter food from Qin LAN. After thinking about it, Chen Xin took out a box of luncheon meat and a cabbage.

    Since we have decided to eat better, it''s not a luxury to add one more dish.

    However, when leaving the storeroom, Chen Xin took a look at the beer and coke he had found from the outside, hesitated for a moment, and finally did not move.

    I''m afraid it will be a long time before the production of wine and drinks will resume in this end of life environment. Basically, what we can drink is the storage before the disaster. If we use a little, we can use less.

    It''s like the coke and beer Chen Xin found. Wheat is needed for brewing beer, but now it''s a luxury to brew beer with wheat.

    Coke may still be produced, but I''m afraid it will become something like a high-end luxury.

    So for the coke and beer that he found, Chen Xin won''t touch them easily before they expire.

    Unless it''s something that makes him happy enough, he''ll consider opening a can to celebrate.

    Open the can of pork, pour the stewed meat and congealed fat into the pot and heat it on the induction cooker. At this time, Chen Xin cleans up the cabbage, cuts it up with the lunch meat, and plans to fry it.

    When the gravy in the pot began to bubble, Chen Xin poured the meat and the juice back into the can.

    As for the remaining oil and a little juice in the pot, Chen Xin did not pour it out or wash it. Instead, he put it back on the induction cooker. Then he poured cabbage and lunch meat into the pot and stir fried them.

    At the end of the day, there is a shortage of materials. If you can save something like oil and salt, you can save it. After all, it''s hard for Qin LAN to get condiments like oil and salt.
