Lin Xi looked around and roughly understood his mistake.
By the standards of the prosperous Tang Dynasty, the residents of this settlement were extremely poor and technologically backward. Several large-scale power generation technologies are unavailable due to lack of electrical equipment, and low oxygen levels make combustion very difficult, making small generators impossible.
As for batteries, even fuel cells or biological batteries, the technical level is far beyond the current level in the settlement, let alone polymer batteries. Micro fusion batteries were also cutting-edge technology in the prosperous Tang Dynasty.
The simplest and cheapest way is to add oxidizer directly to the fuel.
Everyone went up to the second floor. There were two bedrooms and a storage room on the second floor. There were several guns and some ammunition, as well as knives, armor and some special hunting tools.
There is a ladder on the second floor leading to the top floor, and the sealed exit door is slightly opened.
Li Ruobai went out to take a look, saw the open bunker on the third floor, and climbed back to the second floor.
Chu Jungui looked at an oxygen storage tank placed against the wall. The meter on the oxygen tank showed that it was still one-third full. This old-fashioned pressure gauge seemed quite novel to him. Even in Xinzheng, these are old antiques that can only be seen in museums.
Chu Jungui sensed that the oxygen content in the room was about 18% and was still slowly declining. The four armors all have built-in air filtration and oxygen supply capabilities, and they don't feel anything about it. Om was a little short of breath. He stretched out his hand to unscrew the oxygen tank, let out some oxygen, and put some more into the small tank he was carrying.
Li Ruobai touched the oxygen tank and asked, "Where does the oxygen come from?"
"We have our own oxygen supply machine. But the raw materials need to be purchased from the city."
"Go and have a look."
"I'll take you there."
Aum led the four people out, then walked into the next door house, and said: "This is Bonnie's home. Her husband died two years ago and her life was very difficult. You can go in and take a look, and you will have a general understanding of us." What kind of life do the people here live?”
The four of them were also curious, so naturally they would not object. The opportunity to look at human life hundreds of years ago like this is rare.
Bonnie's home has only two floors and is much smaller. There is only one bedroom on the second floor, and the oxygen tanks used are much smaller. As for the first floor, the number of carbon rods used as fuel is also very small.
Oxygen and carbon rods with additives are the common currency for people in the settlement. If you want to add another thing, it is weapons and ammunition. These three kinds of things are very rare in Bonnie's family. It is obvious that she is really poor.
After seeing the homes of two residents, the next step is some important public facilities in the settlement. The main facilities here include three: oxygen supply station, water room, and cold storage.
The water room provides filtered drinking water, and the cold storage is an indispensable facility for storing food. Both locations are connected to small generators to keep them running.
There are three small generators throughout the settlement, all running on biodiesel, most of which is consumed at the oxygen supply station.
The oxygen supply station here is a three-story building. The first floor is a filling workshop, which is dedicated to filling empty oxygen tanks of various companies. On the second floor are some independent sealed rooms with oxygen levels that can be breathed directly. Some hunters who cannot afford oxygen can live here, and with several people sharing a room, the cost of oxygen can be reduced to a minimum.
There is a heavy iron door on the stairs leading to the third floor, equipped with several locks. Aum took out the keys, opened the locks one by one, pushed open the iron door, led the four people up to the third floor, and then said: "This is the most important place in the entire settlement, and everyone's oxygen source is placed here."
Om pushed open a door, and there were large plastic buckets placed in the back room, all tightly sealed.
Orm pointed to several plastic buckets connected to the pipes on the wall and said: "As long as they are connected to the pipes, oxygen can be provided continuously. One bucket like this is enough for a family to use for a month."
Several other rooms are filled with similar plastic buckets.
Li Ruobai was not polite. He moved an unused bucket, cut the sealing strip with a knife, and opened the lid. He saw that the inside was filled with milky white viscous liquid, with bubbles constantly emerging from it. He picked a little with a knife, scanned the ingredients, and said: "It is a little more efficient than the oxygen supply solution used in the old submarine AIP technology, but there is essentially no difference. It is not at the same level as our solid-state oxygen supply technology. superior."
"Where do these oxygen barrels come from?" Lin Xi asked.
"Bought in the city. Just exchange the old barrel for a new one every time and pay the fee."
"Go to the city hall." Li Ruobai said.
“There’s no city hall here.”
"Then go to your house. Anyway, I want to find a place with a map. Including the city and surrounding areas, don't tell me there isn't one."
Orm sighed and said, "Go to my house."
After leaving the oxygen supply station, we saw several small shops on the road, some selling game furs, and some selling homemade tools, ammunition, and so on. The shops are all empty now, and the shopkeepers are still standing outside the settlement.
Aum's home is the only four-story building in the entire settlement. It not only has a kitchen, a living room, and even a dedicated bathroom. Here, hot water is also a luxury. Anywhere fuel is used requires a combustion accelerant, which is equivalent to consuming oxygen.
Orm even has a study room of his own. There is a topographic map of the surrounding area hanging on the wall. It not only marks the city, but also the locations of five or six settlements. There are also some special marks, which should be some resources. point of production.
All four of them had helmet camera and scanning functions, and they memorized the map at a glance.
"Is there a larger map?"
"What do you want that thing for?" Om felt confused.
"Don't you want to see a distant place?"
"My grandfather's generation built this settlement. Until now, there are still many places around it that have not been thoroughly explored. If you want to go far, you must have fuel and oxygen."
Li Ruobai and Lin Xi looked at each other, and then asked: "Where are you from? How did you get to this planet? How long have you been here?"
Aum took off his breathing mask, took a sip of water, and said, "This happened so long ago that it has almost become a legend. Fortunately, my father told me some stories when he was alive."
"It is said that our ancestors came from the depths of the universe. They lost their way while exploring the stars and came here. The immigrant spacecraft they took at that time was no longer capable of making another voyage, so they had to settle here."
Li Ruobai's eyes lit up and he asked, "Where is that immigration spaceship now?"
Once you find the immigrant ship, you can naturally find out where it comes from. Hundreds of years ago, the space that humans could explore was quite limited. Once you find its starting point, you will naturally find your way home.
Orm glanced at him, pointed to the huge brown planet on the sky outside the window, and said, "It's up there."
Li Ruobai immediately sneered, "Your joke is not funny."
