Xu Xin thought about it and decided to plant some fruits and vegetables first.
There is no need to plant too many fruits. Green-level fruits alone have no other function except filling the stomach and quenching thirst.
In addition, the current situation is that there are abundant fruits in the jungle, and everyone has enough fruits, so there is basically no market for growing them. Green-grade poplars and pine trees are too tall, and even if they are five or six meters high inside the house, they are not enough, so there is no way to grow them inside the house.
Xu Xin planted a row of apple trees and a row of orange trees near the middle of the house. Both trees can be maintained at a height of about three meters, which is suitable for indoor planting.
Xu Xin randomly scattered some red berry or strawberry seeds in the remaining space. Plant them first and then change them when he finds green-level materials that can be planted indoors.
Xu Xin had considered growing cotton, but the yield from just these few pots was too pitiful, so he decided to give up. After this rainy season was over, he would open up a field below to plant cotton.
The pine and birch forests downstairs have not yet fully grown, and I don’t know if they will be affected by the heavy rain.
Coco was also on the top floor at this time, staring blankly at the sky above the glass, as if she was attracted by the sky.
Xu Xin picked up Coco and prepared to take it back to the third floor.
"Hmm!" Coco suddenly pointed to the sky.
"There is danger!" Xu Xin suddenly became alert.
"Bing." Coco shook her head and pointed to the sky, "Bing!"
"No danger?" Xu Xin was a little puzzled. "What do you mean? Are you saying there is something in the sky?"
"Hmm!" Coco nodded.
"Isn't this thing dangerous?" Xu Xin also looked up at the sky. Through the glass, he could only see a dense cluster of stars.
Coco shook his head, then nodded, then scratched his little head. Probably not knowing what to say, he buried his head in Xu Xin's arms.
Xu Xin stroked its swaying tail and thought, "Perhaps, it's because the next activity is during the rainy season, so it may be able to sense the weather changes in advance. Or maybe..."
He looked up at the sky and narrowed his eyes.
"Or maybe this rainy season was created by something, and now this thing is in the sky."
No matter what, Xu Xin is now unable to fight back. All he has to do is simply survive.
Everything inside the house has basically been taken care of, and the next step is to add weapons outside the house.
He now only has one heavy crossbow outside the house, and the range of its attack is too small. The tree house has four sides, so he needs to install three more.
When he hunted the blood-marked cat before, he also obtained two special materials that could be used to strengthen the heavy crossbow.
Xu Xin sent a message to Li Wenxi, asking for some iron blocks.
Li Wenxi’s reply was not slow, but the content was not about a transaction.
"Xu Xin, I got new metal ore!"
Hmm? New metal ore
Xu Xin immediately put the transaction matter aside and directly made a video call to Li Wenxi.
Li Wenxi in the video was also a little excited: "Xu Xin! Metal! A brand new metal, and it's blue grade!"
At this time, Li Wenxi had a black stone in his hand. It looked inconspicuous, but under Xu Xin's identification ability, it was emitting a blue light.
"What kind of ore is this? Did you get it from a chest in a dungeon?"
"No, I mined it. The exit of the dungeon is a mine, and the mine is full of this kind of ore!" Li Wenxi said as he raised another piece of black metal. Although it was black, it still had a metallic luster.
The piece of metal was very heavy, and judging from her appearance, it seemed like it was quite difficult for her to lift it.
"These are smelted metal blocks with strange names, called black gold ore and black gold blocks! But I don't know what they are used for."
Mine cave! There will be endless ore!
I don’t know what kind of ability this rich woman has, but her family has more and more mines, which is really enviable.
“Well... it’s useless for you to hold it, right? How about..." Xu Xin really wanted the black gold nugget in Li Wenxi’s hand. With his ability, as long as he got the black gold nugget and combined it with the existing raw materials, he could unlock the formula of black gold!
"Hehe, I know you have the ability to make metal tools. I give this to you. How are you going to repay me? Ah!" Li Wenxi smiled and shook the black gold nugget in his hand, but the black gold nugget was too heavy and he lost his grip and it fell to the ground.
With a "bang" sound, Li Wenxi quickly picked up the black gold nugget and patted his chest, "Fortunately, fortunately, the floor was not damaged."
From her tone, it seemed that she was planning to give the black gold to him. Xu Xin breathed a sigh of relief.
"How about you have a share of everything I make related to black gold?" Xu Xin said with a smile.
"You said it, and you can't go back on your word. I'll provide you with the raw materials, and you have to do the work for me for free!"
Li Wenxi was not so naive. But as Xu Xin said, she could only use this metal as a brick in her hand. It was also very heavy and not easy to use. It would be better to give it to someone who could use it, so that both parties could achieve a win-win cooperation.
"Free OEM?" Xu Xin looked troubled. "Then your raw materials..."
"I won't charge you any money! You can use as much as you want, but you have to make a copy for me of whatever you make!" Li Wenxi was wealthy and generous. With a wave of her hand, she initiated a transaction and gave the piece of metal in her hand to Xu Xin for free.
This profit is equivalent to Xu Xin exchanging one finished product for two raw materials, with a profit margin of 100%!
Cooperation of technology and resources, win-win!
Xu Xin received the piece of black gold. The moment he held it in his hand, his hand sank and he almost dropped it.
So heavy!
Black Gold Block (Blue): The hardness and toughness have reached an extreme balance. It is a very tough metal block with extremely strong conductivity!
Highly conductive!
Could it be…
Xu Xin immediately opened the production list, and the newly appeared production blueprint made him open his eyes wide.
Basic Electrical Appliance Crafting Table (Blue): It can be used to craft basic electrical appliances, provided that the crafting method has been unlocked. It requires 5 Black Gold Blocks (Blue), 20 Iron Blocks (Green), and 20 Wood Blocks (Green).
It's an electrical appliance!
Xu Xin was instantly excited. He thought that he had to obtain copper and silver blocks before he could unlock the electrical appliances. He didn't expect that the electrical appliance production table required this special metal.
"How many black gold bars do you have now?" Xu Xin asked Li Wenxi hurriedly.
"I have already refined five or six blocks. How come the blueprint has been unlocked? What is it?" Li Wenxi was a little curious. The black gold block in her hand was described as a very tough metal with special properties, but it did not say what function it had.
"Electrical appliances! We could probably use some electrical appliances. Give me four more and I want to build a crafting table!"
"Is this true?! I'll get it for you!" Li Wenxi's eyes widened, and she immediately left the screen. After about ten seconds, she ran back and directly initiated a transaction with Xu Xin, giving him four pieces of black gold.
Xu Xin immediately made the basic electrical appliance production table (blue).
Then he couldn't wait to open the list of the production station.
To his disappointment, there was only one crafting item on the list at this point: a lightning rod.
This... Lightning rod, is it also considered an electrical appliance
Lightning Rod (Blue): A metal needle that can avoid lightning damage. The absorbed lightning can provide electricity for the tree house. Requires Black Gold Block (Blue) *5
Xu Xin suddenly no longer felt that the lightning rod was useless.
This is a charger for thunderstorms!
However... there is only this one production item on this list, and there are no other electrical appliances, nor any devices for storing electricity. This... at this stage, it really has no other use except for lightning protection.
But it is a timely relief. After all, the rainy season is coming soon.
"Why are there no other electrical appliances? Do they still need copper and silver mines?" Xu Xin pondered. "My ability is to have all kinds of raw materials to unlock the blueprint. It seems that those electrical appliances need other materials."
Li Wenxi's voice came from the other side of the screen: "How is it? What kind of electrical appliances can be made? Can we finally have electricity?"
"I'm sorry to disappoint you." Xu Xin returned to the screen and spread his hands helplessly. "It seems that other metals are needed to unlock the electrical appliances. The crafting table can only make lightning rods. You should pay more attention to copper mines, silver mines and the like in the future."
"Ah~ I'm so happy for nothing. I've been keeping an eye on the copper mine, but I haven't found it yet. But a lightning rod will do, too. The rainy season is coming soon. How many black gold blocks do you need to make it? I'll give it to you!"
"It takes five black gold bars to make one, and you give me ten." Xu Xin calculated it very clearly.
"Ah? So many? You are not trying to trick me into cheating me out of my mine, are you?" Li Wenxi looked at Xu Xin suspiciously, and then tried to persuade Xu Xin earnestly, "Actually, you don't have to cheat me out of my mine. Just make me one and use it as you like."
"Who cheated you out of your mine?" Xu Xin rolled his eyes at her and sent her the properties of the lightning rod. "See for yourself."
"I really need so much..." Li Wenxi touched his head embarrassedly, "Then wait a moment, let me see if the ore I brought back this time is enough. It's a long way there, and I don't know when I can get a means of transportation."
"…" Xu Xin resisted the urge to brag about his Silver King to her, fearing that Li Wenxi would feel unbalanced. Fortunately, the Silver King usually rested in the corner, and the angle of the video screen could not see it at all.
"Wait a moment, it's enough, but the refining process is very slow. How about you make me a crafting table? Then I can do it myself."
"You haven't unlocked the crafting blueprint, so you can't use the crafting table even if you're given one."
"What you said makes sense. Let's forget it for now. I'll give you the black gold nugget in two hours."
"Okay. Give me some iron blocks. I don't have enough here."
"Oh, okay. I hadn't noticed until now, but you decorated the tree house very beautifully. That's amazing!"
"Ha, I can't keep living this rough forever."
After hanging up the video, Xu Xin immediately made two blue-level heavy crossbows made of special materials and a normal blue-level heavy crossbow, and placed them in the other three directions. In this way, the attack range of the heavy crossbow could cover the entire area around the tree house.
However, it is not full coverage, because the heavy crossbow is located lower on the wall of the first floor. It can attack below the canopy of the tree house, but it cannot attack positions too close to the trunk, nor can it attack the trunk.
If you want to attack these positions, Xu Xin can only come out by himself, let the roots of the tree house hang him under the tree canopy, and then attack with a crossbow or a spear.
In this way, he renovated the tree house inside and out, and finally finished all the work that needed to be done.
Next, Xu Xin has to decide an important thing.
Should we give the Silver King a mutation potion to turn him into a mutant
