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 the discussion at all, but watched as the oxygen he hung on the trading floor was constantly being drained.

"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 mind, Xiao Yi said with some 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 approximately 888.96g, which is 0.89kg. This calculated data is quite accurate.

Those with more should be regarded as higher-level humans needing more oxygen!

Xiao Yi was completely hung up on the six hundred liters of oxygen in the trading floor. Because it was expensive, those who particularly needed oxygen had already taken action, while the rest of the survivors were hesitant.

Of course, there are some survivors who endure and persist until they capture the supply box. It is possible that resources such as oxygen can be found in the supply box!

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

"The transaction was successful and the materials obtained: cornerstone * 6 million."

"Trigger four times the harvest and obtain materials: cornerstone * 24 million."

Just the current transaction has completely solved Xiao Yi's problem of not having a foundation in one fell swoop!

"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 of escape cabin] Materials required: cornerstone*1 per cubic meter, secret gold*1.

One unit of Unique Gold is 100g.

If the secret gold that Xiao Yi just opened was not harvested four times, it would only be equivalent to harvesting one unit of secret gold.

"It seems that in addition to foundation stones, dark gold is also a very important material!" Xiao Yi secretly thought.

Xiao Yi had already harvested dark gold, a substance like dark gold, at the East China Sea Dragon Palace near the Mermaid Tribe!

It's just that you can't bring anything with you when you enter this stage, so the secret gold obtained from the East China Sea Dragon Palace is still in the Yi Ranpin Alliance's warehouse.

Now we can only find solutions from other survivors!

Thinking of this, Xiao Yi immediately listed 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 1,000 groups. As soon as he put them up, they were all sold out before Xiao Yi could react!

"Obtained materials: dark gold * 100,000 g (1,000 units)."

"Trigger four times the harvest and obtain materials: dark gold * 400,000g (4000 units)."

In the public channel on the island monument, everyone started discussing again.

"How come this Yi Ranpin has so much oxygen? It's completely illogical!"

"Are we still pursuing logic at this time?"

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

"It can be opened from the supply box. If you study the island monument's manufacturing interface, you will know what its use is!"

"This thing can expand our survival warehouse!"

"You can't just sell it to others!"

"Now that I'm about to suffocate to death, will I still think about it so much?"

"Now we have to try to survive as soon as possible!"

After getting so many foundation stones and secret gold, Xiao Yi immediately started to expand the escape cabin.

According to his habit of living on land, Xiao Yi expanded the escape cabin into a space of 3 meters high and 36 meters long and wide.

The original space size was 8 cubic meters, but 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 is this window?" Xiao Yi looked at the expanded escape cabin in confusion and muttered.

"Cornerstone and secret gold can only expand the cabin, but cannot expand 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 photovoltaic panels have started 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 is fully charged, and it is released outside the escape cabin to collect all the meteorites that have hit before and the meteorites that have been captured.

When the collection is completed, these meteorites have all disappeared.

After collecting these two meteorites, we obtained some metals and 20kg of water.

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

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

Although Xiao Yi's escape cabin has been greatly expanded, the number of survivors in the escape cabin 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 monument, but began to use the metal he had just obtained to separate several rooms in the escape cabin!

This escape cabin seems to have taken into consideration the partition situation, 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 material shape, no manufacturing drawings are needed.

Xiao Yi used the island monument to make several metal partitions 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 is the only one in this escape cabin, if there is no partition, he will always feel like being spied on!

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

In this weightless feeling, urinating and defecating feels like a problem.

It doesn't mean that there is no gravity if the monster cannot be pulled out, but what to do after it is pulled out is the most important question.

Can you imagine an entire escape pod with flying everywhere?

So even if Xiao Yi feels a little uncomfortable now, he still endures it.

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

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

"I also want to know!"

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