Chapter 80: bargain

Qin Lan brought a lot of materials on the list, but these materials need to be

exchanged by Chen Xin with the vegetables produced in his refuge. The list

also lists the exchange ratio that the SWAT team deems appropriate after

discussion.

Of course, Chen Xin has no objection to the exchange of materials, which is

also very good for him, but he has different opinions on the proportion of

material exchanges.

"One hundred catties of fresh vegetables are exchanged for five bags of

cement? This ratio is acceptable." Chen Xin looked at the exchange ratio

marked on the list, checking one by one: "But the steel bar is a bit

exaggerated, isn't it? Twenty catties of vegetables can be used. Change a

steel bar?"

Steel bars are extremely useful for Chen Xin. Apart from anything else,

reinforced concrete must be used to reinforce the door of the shelter.

"What we provide is standard φ12X12 steel bars, and you know that there are no

steel plants in this city. All of these rely on railway input, and the price

is understandable." Qin Lan explained to Chen Xin.

Although the two used to be boy and girl friends, they obviously did not

hesitate their past feelings when they were bargaining.

"But only twenty catties of vegetables can be exchanged for a steel bar. The

price is still outrageous. I think ten catties is an acceptable price." Chen

Xin opened the mouth and cut the exchange rate in half, but looked at Qin Lan.

Waiting for her to bargain.

As expected, Qin Lan shook her head and refused directly: "Ten Jin is too

little, at most 18 Jin."

However, Chen Xin refused to give up, still repeating: "Ten Jin, or I will

find someone else to change it."

"This is impossible. Even if you put it before the disaster, you can't

exchange ten catties of cabbage for a steel bar." Qin Lan shook her head

vigorously, but made a compromise: "Fifteen catties, no less. "

Hearing Qin Lan's words, Chen Xin laughed and said to her: "One step back,

twelve catties, let me get fifty steel bars first. I need them urgently."

"Need urgently? What are you going to do, Axin? Need so much steel?" Qin Lan

suddenly became curious when he heard Chen Xin's urgent need.

Chen Xin said directly: "The end of the world has been coming for three

months, and the temperature is almost close to freezing. Before freezing, I

plan to reinforce the door of the refuge. So in addition to steel bars,

cement, sand and steel plates are needed. , I can accept the exchange ratio of

these building materials, so let's ship them together as soon as possible."

Hearing Chen Xin said that it would be used to reinforce the door of the

refuge, Qin Lan nodded clearly, and agreed very happily.

At present, the official shelters are also undergoing large-scale expansion

work. All shelters have been allocated a large amount of construction

materials. The amount of materials required by Chen Xin is not large. The SWAT

team only needs to allocate a little from its own materials. Able to meet his

needs.

After discussing the demand for construction materials, Chen Xin put forward a

demand that was not on the list: "Alan, can you help me get some glass? It's

best to be a large glass tube like a cylinder. An aquarium with this shape is

even better, and there is also a vacuum pump."

"You can get it, but Axin what do you want these things?" Qin Lan asked

strangely.

Chen Xin smiled and explained: "The aquarium can be transformed into the

suggested algae oxygen generator. Living in an underground shelter will

definitely have oxygen problems. I need one myself, and Dragon Mother also

needs one. I can help her make one. You can exchange all the good wine in her

place. Drinking in cold weather can keep you warm."

"You're not a Maozi, why don't you drink to keep warm!" Although Qin Lan

complained like this, she still agreed to Chen Xin's request and wrote down

what Chen Xin wanted in her portable notebook.

The two again checked the exchange ratios of the various materials on the

list, as well as the items outside the order that Chen Xin added, and this

ended the bargaining between the two.

After the bargaining was over, the topic between the three became much easier,

and Chen Xin also asked about some topics that interest him.

"Speaking of which is the main food in the refuge now? Isn't it really mouse,

earthworm and mushroom soup?" Chen Xin joked.

But rats, earthworms and mushrooms are indeed all animals and plants suitable

for raising in low temperature and underground without light, and they are

also the main food sources of refuges announced by the state before the

disaster.

In response to this question, Ding Ning just shrugged and leaned on the sofa

in Chen Xin’s living room: “I just evacuated the shelter recently. It’s not

very clear, but what I ate is basically rat meat stewed with potatoes and

mushrooms. It's weird to be able to manage."

“The country has mobilized a lot of rice before the disaster. It’s not strange

to have rice to eat now.” Qin Lan knows a little bit better than Ding Ning, so

she explained to Chen Xin: “As for mushrooms and potatoes, mushrooms are

currently every refuge. For all the things that are being grown, the yield of

mushroom bags provided by the state is good, and now it can be harvested once

a month. If the planting area is not enough, mushrooms alone can already meet

the food needs."

Speaking of this, Qin Lan paused before continuing: "As for potatoes, the

country does not promote large-scale cultivation of potatoes. Although these

things are high-yielding, the demand for soil and fertilizer is also high,

which is not as stable as mushrooms.

It also consumes water and electricity, and the general refuge does not have

the conditions for large-scale planting. Therefore, the city has opened a

special underground planting area near the power plant to grow potatoes, and

the output is not too high. "

Chen Xin nodded in understanding when Qin Lan said this.

In fact, when he built the shelter, the first thing he thought of was planting

potatoes.

Thanks to the blessing of the "Martian Rescue" that year, everyone knows that

planting potatoes can survive, so I feel that the end times are now. Shouldn't

you plant potatoes at this time?

Especially in various traversing novels, in addition to burning glass to make

soap through ancient times, finding potatoes has almost become a must-do.

It seems that everyone thinks this is a kind of fetish. The yield of several

thousand catties per mu of crops is undoubtedly a dimensionality reduction

blow for traditional agriculture that may be less than one-tenth of the yield

of potatoes.

Potatoes do have many advantages. First of all, the yield is naturally high. A

few thousand catties per mu seems to be a normal yield for potatoes.

Secondly, potatoes are very suitable for growing in alpine regions. Mongolia

in the Yan country and Siberia in Lucia are the main production areas for

growing potatoes. They can still grow healthily in an environment where the

temperature is only 10 degrees or less, without too much water. Irrigation can

guarantee a higher yield.

Moreover, potatoes are also nutritious and rich in starch. They can provide a

lot of calories and nutrients to the human body in a cold environment. They

are indeed important foods for life.

But potatoes are not perfect.
