Chapter 30: Sea salt extractor, tap water system

"[Sea Salt Extractor] (Class B)."

Xiao Yi has been thinking about the issue of salt for a long time, but he has never opened it, but Su Wan actually opened it first.

"It seems that you are lucky!" Xiao Yi said with emotion, "Why are you still hesitating, hurry up and create it, don't forget to give me some points!"

If you don't eat salt for a short time, there will be no problem, but if you don't eat salt for a long time, the human body will lack sodium, which will lead to lack of energy.

After all, sodium ions are necessary for transmitting information in the nervous system, and muscle contractions and heart beating are also related to sodium ions.

However, it is fortunate that they are at sea. Even if they don't eat salt and eat some seafood such as sea fish, they can supplement some sodium in disguise.

But Xiao Yi is tired of eating sea fish all day long. He wants to change his taste. It is best to eat some vegetarian dishes!

Su Wan shook her head and said, "No, let's make it for you. I don't have a place to put it here, and the materials I need are not available here. When you build it, just give me some."

Hearing Su Wan say this, Xiao Yi didn't refuse, nodded and said, "That's okay, give me the deal!"

Su Wan traded the sea salt extractor on a private channel.

"[Sea Salt Extractor] (Class B): Wood*5, Glass*10, Linen*20, Metal Sheet*10, Plastic*5."

Taking a look at his supplies, he found that the glass was still two units short, Xiao Yi felt helpless and immediately sent a message to Jiang Yuntian and Su Wan.

"Is there any glass? I need two units of glass. If everyone doesn't have it, I'll go to the trading floor to find it."

Seeing Xiao Yi's message, the two responded almost instantly. After all, the island is not very busy, just watch the flow of the material box and take action in time!

"I have one!" Su Wan replied, "[Glass]*1 No transaction."

"I have." Jiang Yuntian replied, and without hesitation, he traded the glass over, "[Glass]*2 No transaction."

Xiao Yi immediately agreed with all of them, and the supplies were immediately gathered, so he clicked to make.

A sea salt extractor appeared in the manufacturing space, and Xiao Yi put the sea salt extractor in the kitchen of the apartment.

Xiao Yi came to the empty kitchen and saw a machine placed in the corner.

"Sea salt extractor (grade B): It can filter out the impurities in sea salt well to get refined salt, add a little salt, it is good for your body."

"Extraction efficiency: 40g of refined salt can be extracted every day, and the seawater residue in the purifier can be used to improve the extraction efficiency!"

Seeing the system prompt, Xiao Yi said in surprise: "I didn't expect to be able to use the purified residue!"

But think about it and understand, the sea water purifier is to intercept all the rest of the seawater materials, and only let pure water pass through. The salt concentration in this residue must be higher than that of seawater!

In this way, the sea salt extractor can extract sea salt from seawater with higher concentration, and the efficiency is naturally higher.

Xiao Yi looked at his seawater purifier and found that he was just about to finish purifying a bucket. He poured all the liquid remaining at the bottom of the bucket into the sea salt extractor.

The extractor started working right away!

The rest of the time was waiting, Xiao Yi switched back to the manufacturing interface, and also manufactured the C-class water purifier that Jiang Yuntian gave him, and placed it in the living room side by side with the A-class water purifier.

"[Water purifier] (Class C): It can purify seawater into pure water. When the seawater supply is sufficient, it can produce 20ml of pure water per hour. The capacity of seawater in the machine is 500ml, and the capacity of pure water is 500ml. Lack of automation, manual work is required Add sea water!"

This efficiency is four times worse than that of A-class water purifiers!

However, it is always good to have one more water purifier. At least you can have more pure water every day, and those ordinary crops no longer need to be watered with grade A pure water.

This also relieved the pressure of pure water on Xiao Yi's side.

After placing these, Xiao Yi went out and wandered around his island.

"The bigger the area, the more lonely you feel!" Xiao Yi said with emotion, then patted Wang Cai, who was following him, and walked to the chicken coop.

The eggs still don't seem to respond, and it's not known when the chicks will hatch.

There are already three material boxes on the shore, and the fully automatic fishing net is still tirelessly patrolling according to the preset route.

Looking at the three supply boxes, Xiao Yi secretly said, "Do you really wait like this? If the 10% probability still fails to trigger after ten days, why don't you have to wait forever!"

"No, I can't wait. These ten days may make me fall behind. If I encounter other powerful survivors in the future, if I can't resist, then everything will be in vain!"

Xiao Yi doesn't think he is the only lucky person in the world.

Taking a step back, even if there is only a double probability of one day, a huge gap can be opened.

Open the crate! Xiao Yi decisively walked towards the three material boxes.

"Get supplies: cornerstone*2, bricks*4, plastic*3, spicy strips*100g."

"And spicy strips?" Xiao Yi's eyes widened, and he looked at the contents of the supply box in surprise, "Is this meant to change my taste? Go ahead!"

"Obtained supplies: stove making diagram*1, wood*5, metal sheet*3."

"Obtaining Materials: Drawing of Water System Manufacturing*1."

Although the last material box only showed a manufacturing drawing, Xiao Yi was about to jump up with joy.

With this, he can have running water for bathing!

You know, I used to take a shower every day, but now it has been in the sun for five days, Xiao Yi feels that his body is about to stink!

"[Manufacturing drawing of tap water system]: plastic*200, metal sheet*100, linen*80."

"It's another manufacturing drawing that requires three-digit materials!" Xiao Yi looked at the materials needed for the tap water system manufacturing drawing with a bitter face.

Of course, Xiao Yi also knew that the tap water system was a very huge project and needed these quantities of materials, probably because he was only a single apartment.

If it was a villa, it would be astronomical!

"It is estimated that we still need to trade!" Xiao Yi shook his head, and then sent a message to Jiang Yuntian and Su Wan first.

"It takes a lot of plastic, sheet metal and linen! Lend me if you have any."

"[Plastic] * 20 no deal; [metal sheet] * 15 no deal; [Linen] * 7 no deal."

This is the transaction information sent by Jiang Yuntian.

"[Plastic] *7 no deal; [metal sheet] *6 no deal; [linen] *2 no deal."

This is the transaction information sent by Su Wan.

Xiao Yi naturally would not be polite to them, and all agreed to the transaction.

"Get supplies: plastic*27, sheet metal*21, linen*9."

Looking at the total amount of my own inventory, it is still a lot worse, go to the trading floor!
