Sign in, people are on an isolated island, and they just built a luxury villa by themselves

Chapter 1278 Chemical knowledge, trading dark gold, expansion
Xiao Yi didn't pay attention to everyone's discussion at all, but watched his oxygen hanging on the trading floor constantly being dropped in seconds.

"I didn't expect that 1kg of water could produce so much oxygen!" Xiao Yi muttered in surprise.

Students who have studied chemistry should be able to easily calculate that 1kg of water can be electrolyzed to produce 27.78 moles of oxygen (if the calculation is wrong, please ask the class representative to correct it), and one mole of oxygen is 22.4L under standard conditions.

Let’s popularize basic knowledge here. One mole of any gas is 22.4L under standard conditions.

Therefore, the oxygen produced by electrolysis of 1kg of water is approximately 622L.

After calculating these data in his heart, Xiao Yi said with some surprise: "1kg of water can produce so much oxygen, and it can only last for a day?"

A normal adult breathes more than 2 times, consumes about 0.75kg of oxygen, and exhales 0.9kg of carbon dioxide.

The weight of 27.78 moles of oxygen is about 888.96g, which is 0.89kg, so the calculated data is also correct.

If there are more, it should be considered that high-level humans need more oxygen!
With [-] liters of oxygen, Xiao Yi was completely hung up on the trading floor, because the price was high, those who needed oxygen had already sold, while the rest of the survivors were hesitating.

Of course, there are also some survivors who endured until they captured the material box. It is possible to get oxygen as a resource in the material box!

Xiao Yi is not in a hurry. Anyway, he has already traded 300L of oxygen.

"The transaction is successful, and the materials obtained: cornerstone * 600 million."

"Trigger quadruple harvest, get supplies: cornerstone * 2400 million."

It's just that the current transaction completely solved Xiao Yi's problem of not having a cornerstone!
"The happiness of four times the harvest is real happiness!" Xiao Yi muttered to himself, and then switched the island monument to the construction interface.

[Expansion Escape Pod] Required materials: cornerstone*1 per cubic meter, dark gold*1.

A unit of dark gold is 100g.

If the dark gold that Xiao Yi just offered didn't have a quadruple harvest, it would only be equivalent to harvesting one unit of dark gold.

"It seems that besides the cornerstone, dark gold is also a very important material!" Xiao Yi thought to himself.

Xiao Yi had harvested dark gold a long time ago. He obtained it in the East China Sea Dragon Palace near the Mermaid Clan!
It's just that you can't bring anything with you at this stage, so the dark gold obtained from the East China Sea Dragon Palace is still in the warehouse of the Yiranpin Alliance.

Now I can only find a way from other survivors!
Thinking of this, Xiao Yi immediately placed another transaction on the trading floor.

"[Oxygen]*0.5L trades [Dark Gold]*100g."

There may not be much dark gold available now, so Xiao Yi thought about it and decided to exchange 0.5L of oxygen for one unit of dark gold!

Xiao Yi hung up 1000 groups, and just put them up, before Xiao Yi could react, they were all taken away immediately!
"Materials obtained: dark gold * 10 g (1000 units)."

"Trigger quadruple harvest, obtain materials: dark gold * 40 g (4000 units)."

And in the public channel on the island monument, everyone discussed again.

"How can this Yiranpin have so much oxygen? It's completely illogical!"

"Should we still pursue logic at this time?"

"By the way, what is this dark gold?"

"It can be opened from the material box, and you can find out what it is useful for yourself by studying the manufacturing interface of the Xiadao Monument!"

"This thing can expand our survival warehouse!" "That can't be sold to others casually!"

"Now that I'm almost suffocating to death, do I still think about it so much?"

"Now the first thing to do is to fight for survival!"

After getting so many cornerstones and dark gold, Xiao Yi immediately began to expand the escape pod.

According to his habit of living on land, Xiao Yi expanded the escape pod into a space with a height of 3 meters and a length and width of 36 meters.

The original space size is 8 cubic meters, but the expanded size is 3888 cubic meters, consuming 3880 cornerstones and 3880 units of dark gold!
The cabin damaged by the meteorite impact has also been repaired.

"Where's this window?" Xiao Yi looked at the expanded escape pod suspiciously and muttered.

"The cornerstone and dark gold can only expand the cabin, not the windows," the system prompted.

In other words, although the area has become larger, the windows still only have the six small windows before!
Fortunately, the solar panel has started to generate electricity normally, so the lighting in the escape cabin can already be turned on, at least there is no need to search for the island monument in the dark!

And the collector is fully charged, release it outside the escape cabin, and collect all the meteorites that hit and grabbed before.

When the collection is completed, these meteorites all disappear.

After all the two meteorites were collected, some metals and 20kg of water were obtained.

After the quadruple harvest, Xiao Yi got 80kg of water in his hand.

With so much water, there is no need to consider the oxygen aspect for the time being!

Although Xiao Yi's escape pod has been greatly expanded, the number of survivors in the escape pod has not increased, so the consumption is still the same as before!
Xiao Yi didn't continue to pay attention to the situation on the island monument, but started to use the metal he just obtained to separate several rooms in the escape pod!

This escape pod seems to have considered partitions long ago, so there are grooves in many places that can be stuck in!
The properties of the island monument are the same as before. If you just change the shape of the material, you don't need any manufacturing drawings.

Xiao Yi used the island monument to create a few metal partitions that were three meters long and one meter wide, and then began to partition them.

First of all, it must be the bathroom. You can't just find a corner to solve your personal problems.

Although Xiao Yi was the only one in this escape pod, if there was no partition, he would always feel like he was being spied on!

Of course, even if the bathroom is separated, Xiao Yi doesn't know how to solve his personal problems now!
Under this feeling of weightlessness, it feels like a problem to defecate.

It's not that there's no gravity if you can't pull it out, but what to do after it's pulled out is the most important issue.

Can you imagine the whole escape pod full of flies?
So Xiao Yi has been enduring it even if he feels a little uncomfortable now.

Xiao Yi can bear it now, but some people can't bear it.

"Made, can anyone tell me how to resolve internal conflicts?"

"I also want to know!"

"Just now I opened a food packaged in an aluminum foil bag. After I finished solving the food, I solved the internal conflicts in the aluminum foil bag, and then threw it out from the waste port!"
