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

"Ah? Is the ordinary water electrolysis instrument so useless?" Ergou couldn't help asking.

"Yeah, it is estimated that an ordinary water electrolyzer should only be enough for 0.8 people's oxygen consumption. According to the efficiency of doubling the higher level, the C-level is 1.6 people, and the B-level is 3.2 people, so this B-level water electrolyzer. It must be enough for three people!" Zhu Wu speculated.

"Isn't it possible that I can breathe freely in the future?" Ergou said excitedly.

"There's not enough oxygen on your side?" Zhu Wu frowned and asked, "Say it earlier!"

"[Oxygen] *10L transaction is not available."

"Many thanks to the leader, I can still hold on here!" Ergou said.

"Keep it up! Now we are not lacking in oxygen and electricity, do we need to save so much?" Zhu Wu reprimanded.

"That's right, my B-class solar panel is enough for the two of us. You're welcome. Since everyone follows Yi Ranpin, they're all brothers. There should be no separation between brothers!" Jiang Yun Tian said in a deep voice.

"Yes, thank you Brother Jiang!" Ergou said hurriedly.

Zhu Wu doesn't know how long he can stay in this galaxy. Now he has a companion who can produce electricity and oxygen. This must be a good relationship!

"You're welcome!" Jiang Yuntian replied, "If you're missing anything, you can send it directly to our group, and let's help collect it together, hurry up!"

"Okay!" Ergou replied, "I also found a material box here, I'll grab the material box first!"

Seeing that Jiang Yuntian and the two were getting along fairly well, Zhu Wu felt a little relieved.

"I may have to trouble you to take care of my brother in the future!" Zhu Wu also sent a private chat to Jiang Yuntian.

"It's all said to be a brother, don't be so polite, don't worry, I will definitely bring him to wait for the island owner to come over!" Jiang Yuntian replied.

Now that he has equipment for producing oxygen and electricity, Jiang Yuntian is now confident.

"Okay, if we can really meet on the boss's spaceship, I will definitely invite you to dinner!" Zhu Wu said.

"What's the point of eating, you have to drink, and you have to be good!" Jiang Yuntian replied with a smile.

"Drinking?" Zhu Wu was stunned, "This can't be opened from the material box!"

"Hahaha, I can't open it, but our island owner can do it, do you believe it?" Jiang Yuntian replied.

Zhu Wu was stunned again, and then said: "Of course I believe it, I feel that the boss is omnipotent!"

"Look at what I can drive!" Ergou excitedly sent out a manufacturing drawing.

"[Manufacturing Drawing of Gas Compression Cooler] (Class C)*1."

"Wo Cao, Ergou, did you step on the dog Baba? You can drive it out!" Zhu Wu cried out in shock when he saw the news in the group.

"I didn't even know that this thing would come out!" Ergou couldn't hide the excitement in his heart.

"Great, now the two of us will monopolize the business of oxygen-electric fuel!" Jiang Yuntian said with a smile.

"Yes, according to the previous actions of the boss, the priority should be to collect dark gold. Everyone has a lot of cornerstones, but dark gold is relatively more important!" Zhu Wu said in a deep voice, "The two of you cooperate. , collect all the dark gold, whether it is to expand the escape pod by yourself, or to assist the boss at that time, you can!"

"Well, then let's give priority to the dark gold, and then the cornerstone!" Jiang Yuntian said, "Now let's make the machine in Ergou's hands first!"

"Yes, send out the raw materials you need!"

"Yes!"

Zhu Wu once again listed a few material transactions in the trading hall.

There is no need for publicity this time. He was dropped in seconds as soon as he was hung up.

"Haha, I finally grabbed it this time, you didn't find it!"

"What? Could it be that the boss is selling oxygen on the trading floor again?"

"Yeah, I'm one step slower!"

"When will the boss get more oxygen out, I really can't take it anymore!"

"Brother, it seems that you have just been carrying it for a day, which means that there is still potential, continue to persevere!"

Looking at the news on the public channel, Jiang Yuntian immediately said in the group of three: "Now our oxygen is still sufficient, it is better to hang up and sell some now, one can collect dark gold, and the other can also keep more survivors. , these are our future potential customers!"

"I agree, but the premise is that you leave enough oxygen for yourself first!" Zhu Wu replied.

"It's natural!" Jiang Yuntian said, "Every day we will save more for ourselves!"

He only has a B-class water electrolyzer, and the efficiency of producing oxygen is limited. Naturally, he cannot freely trade oxygen like Xiao Yi does!

"Well, let's get started, I believe many people will be very happy that someone sells oxygen!" Zhu Wu said.

Jiang Yuntian thought for a moment, and then listed 60 groups of transactions on the trading floor.

"[Oxygen]*0.5L Trading [Dark Gold]*2."

After this transaction was hung up, it was also instantly wiped out!

Jiang Yuntian only used 30L of oxygen, in exchange for 120 units of dark gold, this transaction made a lot of money!

At this time, in the public channel, everyone began to discuss again.

"Some bosses actually choose to use oxygen to trade dark gold!"

"Yeah, I grabbed three groups and saved my life!"

"Why didn't I grab it again, Big End of the World, can you sell some more oxygen, I have dark gold!"

Jiang Yuntian saw the information in the public channel and said, "In the future, I will sell some oxygen on the trading floor from time to time. If you need it, go to the trading floor to buy it yourself!"

"Irregular! Boss, did you open a device for making oxygen?"

"It's so awesome, I'm so envious of the boss's luck!"

"Great, as long as I survive, maybe I can drive the same equipment!"

"No matter how poor you are, you can't beg for food. If you don't die, you will always succeed!"

"The end of the world can save a lot of people!"

"In this way, our galaxy can prosper, and the big guy's vision is still very long-term!"

According to the previous calculation, the oxygen produced by the electrolysis of 1kg of water is enough for an adult to breathe, so the B-level water electrolyzer can electrolyze about 3.2kg of water a day.

Jiang Yuntian is going to sell 0.2kg of oxygen electrolyzed from water. The rest of himself and the two dogs each take up 1kg. Each person takes an extra 0.2kg as a backup, and the remaining 0.6kg is used to make fuel.

Of course, we still need to prepare some for Zhu Wu in the early stage. Now I don't know where he will wander, and I don't know how long he will wander. If you prepare more, you can't go wrong!

Just when Jiang Yuntian was doing business in this galaxy, Xiao Yi also opened up a new business.
