Qin Lan, who had finished lunch at Chen Xin's shelter, didn't stay long, and left after helping Chen Xin clean up.

After Qin Lan left, Chen Xin looked directly at the medical supplies placed on the side and chose to upgrade the medical treatment room.

There was still a flash of green light, but instead of creating a room in its place, it had made a hole in the wall of the living room.

The wall was broken down by the green light, which extended to the mountain outside the wall, and soon a hole was dug in the mountain that was large enough to be built into a new room.

When the green light dissipated, a small but fully functional medical room that could even perform surgery appeared in front of Chen Xin's eyes.

With a little excitement, Chen Xin pushed open the door and walked in.

The medical treatment room is not large, but a long room, with a surgical chair at the bottom of the room and a curtain next to it, which seems to be able to be pulled up as a partition for surgery.

Except for the back half of the room, which can be used as a makeshift operating room, the entrance to the room is a small table with what looks like a testing instrument.

Next to the table, against the wall, were two large cabinets, which contained some medicines, as well as surgical instruments.

There is no high-tech component in the entire medical treatment room, and it looks ordinary, except for the surgery, it is not even as good as the school infirmary.

Chen Xin is very satisfied with this, regardless of whether it is advanced or not, whether it is perfect or not, first solve the problem if there is one, and then consider whether to make it better.

After looking around the entire medical treatment room, silently looking at all kinds of things, opening the cabinet and checking it, and even lying down on the operating chair and trying it, Chen Xin felt that this medical treatment room was basically enough as it is now.

After all, in this last days, the medical treatment room for ordinary minor injuries and illnesses is completely sufficient, and as for the diseases or traumas that this medical room can't handle, Chen Xin doesn't feel that he can have enough ability to deal with them.

After all, he is just an outdoor survival enthusiast who has learned first aid for a few days, not a professional doctor.

When it comes to professional doctors, Chen Xin can't help but think about Mo Qingyan's sister, Mo Qingxin is a student of a well-known medical school in Hunan Province, and she should have graduated this year.

But last year, the school was delayed by various things for more than half a year before the start of school, and her last year of clinical internship became a real battle, not to mention, she should have graduated successfully this year because of the meteorite incident, and it is estimated that she will never get a graduation certificate.

Fortunately, this does not affect Mo Qingxin has already learned all the content that should be learned, and the last year is a clinical internship, compared with a formal doctor, what Mo Qingxin lacks is only experience.

Thinking of this, Chen Xin couldn't help but think that if he could let Mo Qingyan and Mo Qingxin move to him, he would not only have two more people to work, but also have a doctor who was inexperienced but professional enough.

But this is just thinking about it, not to mention how he persuaded the Mo sisters to move to his shelter, even if they moved over, two women and a man lived in the same room, not to mention what Chen Xin had thoughts about Mo Qingyan and Mo Qingxin, in case people had any thoughts about him, under the two-to-one, Chen Xin had no ability to refuse and resist.

Therefore, Chen Xin, who didn't want to let these problems bother him, still didn't consider letting others move to the shelter for the time being.

Of course, as the shelter is upgraded, recruitment is inevitable.

After all, with the upgrade of the shelter, a lot of work needs to be done by manpower, and sometimes he can't take care of it alone.

It's just that Chen Xin still needs to think about this matter again, who to invite to his shelter, and how to invite him, this is all a problem.

Before clarifying his thoughts and ideas, and upgrading the shelter, Chen Xin didn't plan to think about it anymore, at most he was looking for who he was going to invite.

After all, even if the shelter upgrade is completed, according to the upgrade plan given by the system, it can only accommodate five people, excluding Chen Xin himself, and the remaining places are only four.

Putting aside his thoughts about recruiting manpower, Chen Xin turned his mind back to the day-to-day maintenance of the shelter.

In addition to refueling the generator and daily cleaning, the maintenance of the planting greenhouse is the heaviest task of Chen Xin's day.

Coming to the planting greenhouse, the vegetables on the hydroponic planting tray have been harvested, and now they are all empty, waiting for Chen Xin to plant again.

The upland rice on the ground has already begun to be filled, and it will be ready for harvest in another month.

The carrots were replanted only last month, and now they are growing well, and if Chen Xin wants to eat them, it is no problem to pluck one and wash it and gnaw it raw.

Although the tender carrots have not yet grown, the taste of the young seedlings is still good.

However, Chen Xin did not do this kind of thing, although he planted a lot of carrots in the field, but the previous harvest had not been eaten, so there was no need to waste it so much.

After checking a cabbage and lettuce planted in the field, and seeing that there was no problem with the growth, Chen Xin took off the planting board on the hydroponic planting tray and prepared for new breeding.

Seed retention is a troublesome job, because cabbage is a biennial plant, and it takes about ten months to keep seeds, even if the temperature in the greenhouse is constant and the growth cycle is relatively fast, it will take several months.

However, lettuce grows relatively fast, and as the first batch of lettuce sown, the lettuce planted by Chen Xin has already flowered and set seeds.

It's just that the seeds are not yet ripe and cannot be harvested yet.

Although lettuce can grow forever if only the outer layer of leaves is peeled and the cabbage is left, it is also time-limited, and it will not grow after a year or two, so Chen Xin still adopts the practice of harvesting the whole plant and leaving the seeds.

After cleaning the planting boards, taking new seeds and putting them on the planting boards, still spraying water to keep them moist, Chen Xin put the planting boards back on the hydroponic tank.

After finishing his work, he couldn't help but knock on his lower back, which was quite sore.

Although it is a person's workload, it will undoubtedly be much easier if there is someone to help you.

Seeing that all the planting boards had been put back into the hydroponic tank, Chen Xin confirmed that there was no problem again, and then left the planting greenhouse.

Although there is not much work to plant in the greenhouse, Chen Xin came out of the greenhouse and glanced at the time on his mobile phone, only to find that it was time for dinner.

Of course, dinner was not as extravagant as lunch, Chen Xin just fried a lettuce and opened a refuge food that Qin Lan sent today, which was considered dinner.
