Xu Xin thought for a while and decided to grow some fruits and vegetables first.

There is no need to plant too many fruits, and pure green fruits have no effect except to satisfy the stomach and quench thirst.

Moreover, in the current situation, there are abundant fruits in the jungle, and everyone is not short of fruits. There is basically no market for them. Green-level poplars and pine trees are too high. Even if the height of the house is five or six meters, there is no way to plant them in the house.

Xu Xin planted a row of apple trees and a row of orange trees near the middle with relatively high ceilings. Both trees can be maintained at a height of about three meters and are suitable for indoor planting.

In the remaining position, Xu Xin casually sprinkled some red berries or strawberry seeds into it. Let's plant it first, and then change it when he finds green-grade materials that can be grown in the house.

It's not that Xu Xin has not considered planting cotton, but the output of these few flowerpots is really poor. Let's forget it. After this rainy season is over, he will open up a field below for planting.

The pine and birch forests downstairs have not yet fully grown, and it is not known whether 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 attracted by the sky.

Xu Xin picked up Coco and prepared to take it back to the third floor.

"Hey!" Coco suddenly pointed to the sky.

"There is danger!" Xu Xin suddenly became alert.

"Hey." Coco shook his head and pointed to the sky, "Hey!"

"No danger?" Xu Xin was a little puzzled, "What do you mean? You mean, is there something in the sky?"

"Hey!" Coco nodded.

"Is this thing not dangerous?" Xu Xin also looked up at the sky, through the glass, only a few stars could be seen.

Coco shook his head and nodded again, then he scratched his little head, maybe he didn't know what to say, and buried his head in Xu Xin's arms.

Xu Xin touched its big tail that couldn't stop swinging, and thought: "Perhaps, because the next event is the rainy season, it may be possible to sense the weather changes in advance. Or..."

He looked up at the sky, his eyes narrowed.

"Or maybe this rainy season is made of something that's in the sky right now."

No matter what, Xu Xin doesn't have the ability to fight now, all he has to do is simply live.

Everything in the house has basically been dealt with properly, and the next step is to add weapons to the outside of the house.

He only has one heavy crossbow outside the house now, and the range that the attack can cover is too small. The tree house is on all sides, and he needs to install three more.

When he hunted the blood striped cat before, he also obtained two special materials, which can be used to strengthen the heavy crossbow.

Xu Xin sent a message to Li Wenxi and wanted some iron nuggets.

Li Wenxi's reply was not slow, but the content was not a transaction.

"Xu Xin, I got a new metal ore!"

Um? New metal ore?

Xu Xin immediately threw the transaction aside and sent a video call directly to Li Wenxi.

Li Wenxi in the video was also a little excited: "Xu Xin! Metal! A brand new metal, still blue!"

At this time, Li Wenxi had a dark stone in his hand, which looked inconspicuous, but under Xu Xin's ability to discern, it radiated blue light.

"What ore is this? You got it from a dungeon chest?"

"No, I mined it. The exit of the dungeon is a mine, and the mine is full of this kind of ore!" Li Wenxi raised another black metal block. Although it was black, it was still glowing. metallic luster.

The metal block is very heavy. Judging from her appearance, it is quite difficult to lift the metal block.

"This is a smelted metal block with a strange name, called black gold ore and black gold nugget! But I don't know what it is used for."

Mine! Wouldn't that be an endless supply of ore!

This little rich woman doesn't know what kind of ability it is. The number of mines at home is increasing, which is really enviable.

"Well... it's useless for you to hold it, right? Why not..." 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 cooperated with his existing raw materials, he could unlock the information about Black gold recipe!

"Hey, I know you have the ability to make metal utensils. I gave this to you, how do you repay me? Ya!" Li Wenxi smiled and shook the black gold nugget in his hand, but the black gold nugget was too heavy, so he didn't hold it firmly. fell to the ground.

With a "bang", Li Wenxi quickly picked up the black gold nugget, then patted her chest, "It's okay, I didn't break the floor."

Listening to her tone, it seems that she has already planned to give the black gold to herself. Xu Xin breathed a sigh of relief.

"You have a share of everything I do that is related to black gold, how about that?" Xu Xin said with a smile.

"What you said, don't go back. I will provide you with raw materials, and you have to work for me for free!"

Li Wenxi is not so naive, but as Xu Xin said, she can only use this metal as a brick in her hand, and it is too heavy to die. .

"Free OEM?" Xu Xin looked troubled, "Then your raw materials..."

"I won't charge you! You can use as much as you want, but you have to make me a copy of everything you make!" Li Wenxi has a lot of money, and with a wave of her small hand, she directly initiates a transaction, taking the piece of metal in her hand. Bai gave it to Xu Xin.

This profit is equivalent to Xu Xin exchanging one finished product for two raw materials, and the profit rate is 100%!

Cooperation of technology and resources, win-win!

Xu Xin received the piece of black gold, and the moment he held it in his hand, his hand sank and he almost missed it.

So heavy!

[Black Gold Nugget (Blue): The hardness and toughness have reached an extreme balance, a very tough metal nugget, and at the same time has a very strong electrical conductivity! 】

Very conductive!

Could it be...

Xu Xin immediately opened the production list, and the new production blueprint made him widen his eyes.

[Basic electrical appliance crafting table (blue): Basic electrical appliances can be crafted, provided that the crafting method is unlocked. Need black gold nugget (blue)*5, iron nugget (green)*20, wood (green)*20]

It's electrical!

Xu Xin was instantly excited. He thought that he would only be able to unlock the electrical appliances after obtaining copper and silver nuggets. Unexpectedly, the electrical appliance making table needed this special metal.

"How many black gold nuggets do you have now?" Xu Xin hurriedly asked Li Wenxi.

"Five or six pieces of gold have been refined, why, unlock the blueprint, what is it?" Li Wenxi was a little curious, the introduction of the black gold nugget in her hand was [a very tough metal with special properties], and did not say yes what function.

"Electricals! We may be able to use electrical appliances, give me four more, and I will make a crafting table!"

"Really?! 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. Gave him four pieces of black gold.

Xu Xin immediately made the [Basic Electric Appliance Making Bench (Blue)].

Then he couldn't wait to open the list of the crafting station.

To his disappointment, there was only one production item on the list at this time: [Lightning Rod].

This... a lightning rod, is it an electrical appliance?

[Lightning Rod (Blue): A metal needle that can avoid lightning damage, and the absorbed lightning can provide electricity to the tree house. Need black gold nugget (blue) *5]

Xu Xin didn't feel that the lightning rod was useless for a moment.

This is a thunderstorm charger!

However... there is only one production item on this list, there are no other electrical appliances, and there is no device for storing electricity. This... At this stage, there is really no use for anything other than lightning protection.

But it's a timely rain, after all, the rainy season is coming soon.

"Why are there no other electrical appliances, do you still need copper mines 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 require other materials."

Li Wenxi's voice came from the screen: "How about it? What kind of electrical appliances can be made, can we finally have electricity?"

"I'm disappointed." Xu Xin returned to the screen and spread out his hands helplessly, "It seems that electrical appliances require other metals to unlock, and only lightning rods can be made in the crafting table. You will pay more attention to copper mines and silver mines in the future. Category."

"Ah~ Bai Xingxing, I have been paying attention to the copper mine, but I haven't found it yet. But lightning rods are also fine, the rainstorm season will soon be coming. How many black gold nuggets are needed to make them, I'll give them to you!"

"It takes five black gold nuggets to make one, you give me ten." Xu Xin calculated it clearly.

"Ah? So much? You lied to me and wanted to mine mine, right?" Li Wenxi looked at Xu Xin suspiciously, and then tried to persuade Xu Xin, "Actually, you don't need to mine mine, as long as you also make a copy for me. , use whatever you want."

"Who's pitting you." Xu Xin rolled her eyes at her angrily, and sent the attributes of the [Lightning Rod], "You can see for yourself."

"I really need so much..." Li Wenxi touched her head embarrassedly, "Then wait a minute, I'll see if the ore I brought back this time is enough. It's a long way to go there, and I don't know what it is. When will you have a means of transportation.”

"..." Xu Xin resisted not bragging about her silver king to her, he was afraid that Li Wenxi would feel unbalanced. Fortunately, the silver king usually rests in the corner, and the angle of the screen video cannot be seen at all.

"Wait a moment. Enough is enough. The refining is very slow. Wait. Why don't you make a crafting table for me too? Then I can do it myself."

"You haven't unlocked the crafting blueprint, and you won't be able to use the crafting table."

"You're right. Let's forget it. I'll give you the black gold nugget in two hours."

"Okay~www.wuxiamtl.com~ Give me some iron blocks, I don't have enough here."

"Oh, well, I just didn't pay attention to it. You decorated the tree house very nicely. It's amazing!"

"Ha, you can't live so rough all the time."

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, so that the attack range of the heavy crossbow could be Covered the entire tree house.

However, it is not fully covered, because the heavy crossbow is located at the bottom of the wall on the first floor, and can attack the underside of the treehouse canopy, but it cannot attack the position 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 crown of the tree, and then attack with a crossbow or a sharp spear.

In this way, he renovated the inside and outside of the tree house, and the busy work was finally over.

Next, Xu Xin has to decide an important matter.

Do you want to give the Silver King a mutant potion to make him a mutant creature?
