Silver King and Mimi, who came to the second floor, saw that Xu Xin was not in any danger, so they went back to lie down and rest. Only Coco stayed on the second floor, climbed to the weapons and armor manufacturing platform next to it, and lay down on it to accompany Xu Xin.

.

Xu Xin continued to study his alchemical abilities.

To make this coordinate (blue), you need too many materials.

The first is this steel block that I don’t know how to refine. Ten more are needed, and they are all blue-level!

He can produce ten pieces of wood (blue), but these ten universal alchemy materials (blue) are really outrageous.

It can be seen from the blueprint that the steps to make a universal alchemy material (blue) are not simple.

First, you need to use a furnace to smelt the ore into iron nuggets (blue) and black gold nuggets (blue), and then refine the two metal nuggets into iron sand (blue) and black gold dust (blue) through the alchemical synthesis station. You also need to prepare mutations.

vine sap.

After preparing these, you can use the alchemy synthesis table to synthesize a universal alchemy material.

And one coordinate actually requires ten universal alchemy materials, which is equivalent to ten blue-level iron blocks and ten blue-level black gold blocks! At the same time, it also requires ten blue-level wood and ten blue-level steel blocks! A whole

Forty blue-level supplies!

Moreover, a single coordinate is of little use. The introduction also mentioned that [transmission can be carried out between coordinates], which means that at least two coordinates are needed to achieve transmission between two points.

Eighty blue-level resources! For them at this stage, this is really an exaggeration!

...Forget it, let's not consider the coordinates for now. This thing is simply not something he can afford alone. Maybe if he needs it in the future, he can crowdfund the materials to make it. After all, it is something that everyone can use together.

Let’s first figure out the refining method of this steel block.

Steel blocks are brand-new metal blocks. As long as he can obtain them, he can unlock new blueprints and make steel weapons, armor, and a series of tools!

He flipped through the production list of the alchemy synthesis table and found a production blueprint among a pile of potions.

[Steel Fire: Add the refined iron block to the furnace together to smelt the same grade of steel block. Requires mutated vine juice*1kg, coal (green)*25]

Found it! Materials that can be used to make steel! They are also made in the alchemy synthesis table!

This is the real alchemy.

This steel fire has no color grade. Any grade of steel block can be smelted. The specific grade depends on the iron block.

However, how to obtain this coal?

This is not the first time he has seen coal appear in the production blueprint. The torches that can be made in the novice stage can be made using coal. But so far, he has not seen anyone selling coal as a resource on the trading platform.

Although he has never made a torch, he knows that a furnace can smelt wood into charcoal, and everyone uses charcoal instead of coal to make torches.

I searched the trading platform and sure enough, no one was selling coal.

It seems you still need to find it yourself.

etc.

The yellow light in his sight was a kind of alchemical material. Since it was buried underground, could it be coal? Generally speaking, coal is buried underground. It is really possible.

Let's go dig it today. With his beloved concubine here, he doesn't even have to do it himself.

Xu Xin walked towards the third floor. He wanted to divide the functional areas inside the treehouse first.

"Hey!" Coco followed him and tugged at Xu Xin's clothes with her little paws.

...Is this little guy hungry? Xu Xin gave it an apple, and it immediately stopped following Xu Xin and sat on the ground holding the apple and started chewing it.

Xu Xin also took out one for breakfast and clicked on the regional channel.

He found that what the survivors on the regional channel discussed most was not the decoration and functional areas, but another matter.

They can decorate the interior of the treehouse!

"Everyone, the glass I made in the furnace is finally useful. It can be used to make glass windows!"

“I can finally separate the bed from the workbench. It’s so stressful to see the workbench every time I open my eyes!”

"Haha, I want to decorate a kitchen!"

Have they finally gained the ability to decorate the interior? Presumably, if they can't decorate the interior, they won't be able to divide the treehouse into functional areas.

Xu Xin's internal decoration ability was obtained from the silver treasure chest in the jungle exploration activity. Not only can she decorate the interior, she can also make heavy crossbows and armor for the exterior. This is what everyone in [Explorer] can do.

Now other survivors can also add internal equipment, but they still cannot make external weapons and armor, and they still need to make and sell them.

Arriving on the third floor, Xu Xin first made an art room wooden sign and placed it in the study.

[It has been detected that there is an art room wooden sign in the room. Do you want to designate this room as an art room? It cannot be changed within seven days after designation. Please consider your choice carefully.]

Sure.

[This room has been designated as an art room. Do you want to allocate an increase? Once allocated, it cannot be canceled. Please consider your choice carefully. 】

[Currently allocable total improvement: 210%]

Xu Xin did not allocate them. He planned to identify all the functional areas and then carry out unified planning and allocation.

He placed a kitchen wooden sign in the kitchen and another dining room wooden sign in the dining room. In this way, his three-story living area has a total of four functional areas: bedroom, kitchen, dining room, and art room.

He came to the fourth-floor plantation house and placed a wooden sign for the plantation house, but strangely, there was no prompt to identify the plantation house this time.

Xu Xin glanced at the stairs. The fourth floor leads directly to the third floor. Could it be that this does not count as a closed room?

He built several more walls and a door to seal off this floor of the plantation house, but there was still no warning.

What's going on?

Xu Xin frowned.

Is it because this room is too big? His first floor is nearly 100 square meters. Perhaps it is because there is an upper limit to the area that can be identified by a wooden sign, so he cannot identify the entire fourth floor as a separate functional area.

He raised his wrist and looked at his watch. Everyone in the [Explorer] was also discussing these functional areas.

Zhao Xiaochuan: "Do you think it would be better to allocate them all to the bedroom? This way we can reduce some sleep time every day and can do more things!"

Li Wenxi: "It seems there are so many things that can be done, and we also have blue-level oranges. I have a lot of mines here, and I plan to add a smelting room and a production room."

This was the first time Li Wenxi told them that he had a lot of mines.

Zhao Xiaochuan: "Little beauty Wen Xi actually has a mine at home!"

Wen Guixin: "Aren't you talking nonsense? Your saltpeter mines were all provided by Wen Xi."

Qi Xuefei: "I can make a special medical room wooden sign here to improve the speed and success rate of my drug development. I'd rather add this one."

Wang Lei: "I want to add a kitchen and a restaurant. The kitchen can improve the effect of food. The most important thing is that the food made will be more filling! Who knows whether there will be a famine like now."

Xu Xin asked in the group: "Have you ever been unable to identify the functional area?"

Qin Yunlong: "Did you not install a door? My bedroom didn't have a door at the beginning, so I couldn't identify it."

Li Wenxi: "I don't have this situation here. It's not because yours is too big." The two of them video chat almost every day, but she knows that the area of ​​Xu Xin's treehouse on each floor is twice as large as theirs.

Ji Chaoyang: "It should be that the area you certified is too small or too large. After my attempts, the area of ​​the functional area needs to be between 10 square meters and 80 square meters. Areas outside this range cannot be certified."

It turns out that's really the case.

Although Xu Xin had already guessed it, he didn't expect that Ji Chaoyang had already calculated the entire area.

Ji Chaoyang also sent a message on the regional channel: "Everyone, the minimum area of ​​​​the functional area is 10 square meters. Survivors who have low tree houses must pay attention. Your single-story area is only about 25 square meters. It must be reasonable.

Divide, if one of the functional areas is too large, the other half cannot be identified."

"Thank you, boss!"

"It turns out that ten square meters is enough! It's stable! Then my two-story tree house can have four functional areas!"

"Is one functional area enough? Now there is not much decoration."

"Hey, it will happen in the future. This second phase has just begun. How about planning ahead?"

"Damn it... I accidentally identified an entire tree house as a bedroom... It can only be changed after seven days. I'm stupid!"

"I would like to call you Emperor Jue!"

After Xu Xin understood the scope, she also began to plan in her mind.

The first floor is about a hundred square meters, and he needs to eliminate twenty square meters. After thinking about it, he immediately surrounded a twenty square meters area in the corner of the fourth floor.

The prompt sounded, and the remaining 80 square meters on the fourth floor was designated as a plantation house.

Xu Xin used blue-grade saltpeter to turn the small space of twenty square meters he had circled into a cold room with a temperature of three or four degrees above zero in a few minutes.

From now on, the green vegetables and fruits grown on the fourth floor that can be stored will be placed on the fourth floor. The temperature of the large cold storage on the first floor is too low, at least 20 to 30 degrees below zero, so green vegetables and fruits cannot be stored.

That's the freezer, and this is the refrigerator.

At this time, many of the green fruits on the fourth floor were ripe. Xu Xin picked some ripe ones and put them in the refrigerator for storage.

After tidying up the living area on the third floor and the planting area on the fourth floor, we got to the second floor, which is the most troublesome.

There are many workbenches on the second floor, such as synthesis benches, furnaces, weapons and armor manufacturing benches, mutant potion synthesis benches, basic electrical appliances production benches, and alchemy synthesis benches, all of which are randomly placed on the second floor.

Looking at the messy second floor that she had arranged, Xu Xin had a headache.

He set aside a fifty-square-meter room and placed the synthesis bench, weapon and armor manufacturing bench, mutated potion synthesis bench, and basic electrical appliance manufacturing bench in it. He also made a [Production Room Wooden Sign] and hung it in this room.
To be continued...
