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

"It's not that I don't want it anymore, but the 20,000 foundation stones are the funds to buy fuel in the future." Mr. Lu replied.

Xiao Yi was slightly startled, and then immediately agreed to the deal.

Because Mr. Lu will definitely need a lot of fuel in the future, there is no problem in putting the money with Xiao Yi first.

After the transaction was completed, Xiao Yi immediately began to collect raw materials for the air compression cooler in the trading hall.

Xiao Yi opened the supply box and did not find any raw materials, but just by looking at the comments on the public channel, Xiao Yi knew that there were still many survivors in the second stage!

It is estimated that there are many trial planets in the first stage, and the one Xiao Yi and the others are on is just one of them!

With so many survivors, there is always some lucky person who can provide the raw materials he needs.

And Xiao Yi now has the oxygen that everyone needs, so he can collect these raw materials very quickly.

In just ten minutes, Xiao Yi gathered all the raw materials, then clicked on the manufacturing interface of the island monument, and soon a machine appeared in front of him.

"Gas compression cooler (Class B): It can be connected to the air purification and balance device to liquefy the gas generated in the air purification and balance device. At the same time, it can be connected to the fuel tank through pipelines. The fuel currently used in the escape cabin is liquid hydrogen and Liquid oxygen! The recommended operation method is as follows:..."

The system prompts sounded, explaining to Xiao Yi how to connect various devices.

Xiao Yi immediately followed the system prompts, consumed the cornerstone and dark gold on the island monument, and connected the gas compression cooler to the air purification balance device and the fuel tank.

Because the air purification balance device is relatively powerful and can electrolyze hydrogen and oxygen instantly as long as water is provided, Xiao Yi needs a lot of water.

Although Xiao Yi still has a lot of water on hand, it is still far from enough for making fuel!

The oxygen produced by the electrolysis of 1kg of water is less than 900 grams, and the hydrogen is only more than 100 grams. If you throw this hydrogen and oxygen into the fuel tank, there will probably be no splash at all!

Calculated according to the volume in the fuel tank, approximately 1kg of liquid oxygen and less than 200g of liquid hydrogen account for 1%.

If you want to fill the fuel tank, you need 100kg of liquid oxygen and the corresponding liquid hydrogen.

Calculated based on this data, Xiao Yi needs at least more than one hundred kilograms of water to fill an empty fuel tank!

So Xiao Yi still needs a lot of water.

Mr. Lu must have also seen Xiao Yi collecting raw materials for the gas compression cooler in the trading hall.

Seeing that Xiao Yi had collected everything, after a while, Mr. Lu felt that he should have made it, so he chatted with Xiao Yi privately and asked: "Boss, how about that machine? Is it easy to use?"

"It's easy to use, but it's a bit wasteful!" Xiao Yi lamented, "It takes about a kilogram of water to get a little fuel!"

There is no need to be too precise, in the future we will calculate based on this ratio!

"One kilogram of water?" Mr. Lu was shocked, "Where can I get this much water?"

Xiao Yi helplessly replied: "Then we can only consider the meteorites nearby!" Xiao Yi replied helplessly.

"Okay, can you trade me some more fuel? I'll grab the nearest meteorite and see if I can collect some water!" Mr. Lu asked cautiously.

"Okay!" Xiao Yi replied.

"[Fuel]*10% Transaction None!"

Xiao Yi initiated such a transaction and then continued: "The fuel pricing is temporarily set at one hundred foundation stones, and you only need fifty."

"Okay, thank you, boss. You can just deduct it from the 20,000 foundation stones!" Mr. Lu replied.

"OK!" Xiao Yi responded.

At this time, the space hook suddenly sounded a beep, and Xiao Yi immediately floated over there.

Sure enough, a supply box had been pulled in.

Xiao Yi immediately opened the supply box.

"Materials obtained: cornerstone*20, water*1kg, space glass*5."

"There's not even food. Are you seeing that I've bought too much food from the trade?" Xiao Yi frowned and muttered.

After putting these things away, Xiao Yi continued to let the space hook continue to operate with the supply box as the target. Taking advantage of the fact that there was enough light and sufficient power to see if there were any more supply boxes refreshed.

Previously on the island, each survivor had six supply boxes every day.

In space, the number of supply boxes should only be less than six. The specific number still needs to be verified in practice.

After setting it up, Xiao Yi floated back to the island monument and continued to read the news in the group.

In the early days, there weren’t many things to do in the escape cabin, so we had to find things to do from public channels.

For example, I got an air compression cooler from Mr. Lu before. If I didn’t watch the public channel, I might have missed this machine!

"My oxygen is almost out, and I haven't got a supply box. If anyone can save me, I will definitely repay him!"

"Brothers upstairs, go peacefully, I will pray for you!"

"When you enter here, you can only save yourself. Do you still think about others giving you things?"

"Mad, my escape capsule was hit by a meteorite. The oxygen has been leaking out continuously. My supplies are almost exhausted. I have been replenishing the oxygen!"

"If the damaged area is not large, just cover it with your hands!"

"Yes, block it with your finger. At least the oxygen won't leak out so quickly!"

"You are all talking nonsense, why don't you use cornerstones and dark gold to repair it?"

"Made, it's like I don't want to repair it. I don't have enough secret gold, and no one is selling it."

"Then there's nothing we can do. Let's quickly find more supply boxes. I hope there will be more secret gold in the supply boxes!"

"Brothers, why is it starting to get dark here again!"

"What? It's dark over there again? The light here is fine, at least I can still observe what's going on outside!"

"Wucao, there is a huge star next to me. It should be a planet. It blocks the light of the star. No wonder it's dark here!"

"No! Since there is a huge planet, wouldn't you be sucked away by it?"

"It doesn't seem like it, at least I don't feel like I'm getting closer to it!"

"I feel like my location should be a meteorite belt! I wonder if there will be any planets blocking my light!"

"Since someone has been blocked, it means that other survivors cannot escape the fate of being blocked!"

"Yeah, it doesn't matter if the light is blocked. What I'm worried about is that we will be captured by the big planet. Then we will probably be trapped on the big planet!"

"Yeah, what should I do?"

"Probably not. We were not captured by the planet in the beginning, and we probably won't be captured now either!"
