Sign in, the Man Is on an Isolated Island, and He Has Just Built a Luxury Villa by Himself

Xiao Yi didn't pay attention to everyone's discussion at all, but watched as the oxygen he hung on the trading floor kept being drained in seconds.

"I didn't expect 1kg of water to 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, ask the class representative to correct it), and one mole of oxygen is 22.4L under standard conditions.

The basic knowledge is popularized here. One mole of any gas is 22.4L in the standard state.

So the oxygen produced by electrolysis of 1kg of water is about 622L.

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

A normal adult breathes more than 20,000 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.

Those who have more are regarded as high-level human beings who need more oxygen!

With 600 liters of oxygen, Xiao Yi was completely hung on the trading floor. Because of the high price, those who especially needed oxygen had already taken action, while the rest of the survivors were hesitant.

Of course, there are also some survivors who endured and persisted until they captured the material box, and it is possible to open the resource such as oxygen in the material box!

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

"The transaction is successful, and materials are obtained: cornerstone * 6 million."

"Trigger quadruple harvest, get supplies: cornerstone * 24 million."

It's just the current transaction that completely solves the problem of Xiao Yi's lack of a cornerstone!

"The joy of harvesting four times is really happy!" Xiao Yi muttered to himself, and then switched the island tablet to the construction interface.

[Expanding the escape pod] Required materials: cornerstone*1 per cubic meter, dark gold*1.

One unit of dark gold is 100g.

If the dark gold that Xiao Yi just offered is not quadrupled, it is only equivalent to harvesting one unit of dark gold.

"It seems that in addition to the cornerstone, dark gold is also a very important material!" Xiao Yi secretly said.

The substance of dark gold, Xiao Yi has long been harvested, was obtained in the East China Sea Dragon Palace near the Mermaid Clan!

It's just that you can't bring anything at this stage, so the dark gold obtained from the East China Sea Dragon Palace is still in the warehouse of the Yi Ran Pin Alliance.

Now I can only figure out a way from other survivors!

Thinking of this, Xiao Yi immediately placed a transaction on the trading floor again.

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

The amount of dark gold that can be issued now may not be many, so Xiao Yi thought about it and prepared to exchange 0.5L of oxygen for one unit of dark gold!

Xiao Yi hung up 1000 groups, and just put it up, Xiao Yi hadn't reacted yet, and was immediately robbed!

"Get supplies: Dark Gold*100,000g (1,000 units)."

"Trigger quadruple harvest, get supplies: Dark Gold * 400,000 g (4,000 units)."

On the public channel on the island tablet, everyone discussed it again.

"How can this Yi Ranpin have so much oxygen? It's totally illogical!"

"Do you still pursue logic at this time?"

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

"It can be opened from the material box, and you will know what it does when you study the manufacturing interface of the Xiashima tablet yourself!"

"This thing can expand our survival warehouse!"

"Then you can't just sell it to others!"

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

"The first thing to do now is to fight to survive!"

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 cabin into a space of 3 meters in height and 36 meters in length and width.

The original space size was 8 cubic meters, and the expanded size was 3888 cubic meters, consuming 3880 cornerstones and 3880 units of dark gold!

The cabin that was previously damaged by the meteorite impact has also been repaired.

"Where's this window?" Xiao Yi muttered as he looked at the expanded escape pod doubtfully.

"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 are still only the six small windows before!

Fortunately, the solar panels have begun to generate electricity normally, so the lighting in the escape cabin can be turned on, at least there is no need to look for the island monument in the dark!

The collector has been fully charged, and it was released to the outside of the escape cabin to collect all the meteorites that hit and grabbed before.

When the collection was completed, these meteorites all disappeared.

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

After quadrupling the harvest, Xiao Yi got 80kg of water in his hands.

With so much water, don't worry about oxygen for the time being!

Although Xiao Yi's escape pod has expanded a lot, the number of survivors in the escape pod has not increased, so the consumption is still the same as before!

Xiao Yi did not continue to pay attention to the situation on the island tablet, but began to use the metal he just obtained to separate several rooms in the escape pod!

This escape pod seems to have long considered the partition situation, so there are grooves in many positions that can be stuck in!

The properties of the island tablet are the same as before, just changing the shape of the material does not require any manufacturing drawings.

Xiao Yi used the island tablet to create several metal partitions three meters long and one meter wide, and then began to partition.

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

Of course, even if the bathroom is separated, Xiao Yi doesn't know how to solve personal problems now!

In this sense of weightlessness, urination and defecation feel like a problem.

It doesn't mean that there is no gravitational pull, but what to do after pulling it out is the most important issue.

Can you imagine flying all over the entire escape pod?

So Xiao Yi has been enduring it even if it is a little easy now.

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

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

"I also want to know!"

"I just opened the food packaged in an aluminum foil bag. After I solved the food, I resolved the internal contradictions in the aluminum foil bag, and then threw it out of the waste hole!"
