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

Fruits don't need to be planted too much. Pure green fruits have no effect other than satisfying one's hunger and quenching one's thirst.

Moreover, in the current situation, there are abundant fruits in the jungle, and everyone has no shortage of fruits, and there is basically no market for the grown ones. Green-level poplars and pine trees are really too tall. Even if the height of the house is five or six meters, there is no way to plant them inside 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 maintain a height of about three meters and are suitable for indoor planting.

In the rest of the place, Xu Xin casually sprinkled some red berry or strawberry seeds into it. Let's plant it first, and wait for him to find green-grade materials that can be planted in the house before changing.

It's not that Xu Xin has never considered growing cotton, but the output of these few flowerpots is really poor, so let's forget it, and when the rainy season is over, he will reclaim a field below to plant it.

The pine forest and birch forest downstairs have not yet fully grown, and it is not known whether they will be affected by the heavy rain.

Ke Ke 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 Ke Ke and prepared to take it back to the third floor.

"Oh!" Coco suddenly pointed to the sky.

"It's dangerous!" Xu Xin suddenly became vigilant.

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

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

"Oh!" Coco nodded.

"Is this thing not dangerous?" Xu Xin also looked up at the sky, through the glass, he could only see stars.

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

Xu Xin stroked its wagging tail, thinking: "Perhaps, it's because the next event is the rainy season, so it might be possible to perceive the change of the weather in advance. Or..."

He looked up at the sky, his eyes narrowed.

"Or maybe something made this rainy season, and it's up there right now."

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

Everything inside the house has basically been dealt with, 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 attack range is too small. The tree house is surrounded by four sides, so he needs to install three more.

When hunting 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, wanting some iron.

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

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

Um? New metal ores?

Xu Xin immediately put aside the matter of the transaction, and directly sent a video call to Li Wenxi.

Li Wenxi in the video is also a little excited: "Xu Xin! Metal! It's a brand new metal, and it's still blue!"

At this time, Li Wenxi held a black lacquered stone in his hand, which looked very inconspicuous, but under Xu Xin's discernment ability, it was emitting a blue light.

"What kind of ore is this? Did you get it from a chest in the 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 raised another black metal block, although it was black, it was still glowing. Metallic luster.

The piece of metal was very heavy, and judging by her appearance, it was quite strenuous to lift the piece of metal.

"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! Isn't that another ore that can't be used up!

This little rich woman doesn't know what kind of ability she has. There are more and more mines at home, which is really enviable.

"Well...it's useless for you to hold it, right? How about..." Xu Xin wanted the black gold nugget in Li Wenxi's hand very much. With his ability, as long as he got the black gold nugget and matched with his existing raw materials, he could unlock about Black gold recipe!

"Hey, I know you have the ability to make metal utensils. I will give this to you. How can you repay me? Ah!" Li Wenxi smiled and shook the black gold nugget in his hand, but the black gold nugget was too heavy, so he couldn't hold it firmly. fell to the ground.

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

Judging from 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 it?" Xu Xin smiled.

"What you said, you are not allowed to go back on your word. I will provide you with raw materials, and you have to do it for me for free!"

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

"Free OEM?" Xu Xin showed a troubled look, "Then your raw materials..."

"You won't be charged! You can use as much as you want, but I have to make a copy of everything you make!" Li Wenxi is rich and powerful, and with a wave of her little hand, she directly initiated the transaction, and the piece of metal in her hand It was given to Xu Xin for nothing.

This profit is equivalent to Xu Xin exchanging one finished product for two raw materials, with a 100% profit margin!

The cooperation of technology and resources is a win-win situation!

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): An extreme balance of hardness and toughness, a very tough metal block, and also has extremely strong electrical conductivity! 】

Very conductive!

Could it be...

Xu Xin immediately opened the production list, and the newly appeared production blueprint made his eyes widen.

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

It's electrical!

Xu Xin became excited instantly. He thought that he could unlock the electrical appliances only after obtaining copper and silver nuggets, but he didn't expect that what the electrical appliance making table needed was this special metal.

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

"I have already refined five or six pieces. Why, the blueprint has been unlocked. 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 she did not say that there was any. what function.

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

"Really?! I'll get it for you!" Li Wenxi's eyes widened, and she immediately left from 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 Electrical Appliance Production Bench (Blue)].

Then he couldn't wait to open the list of production stations.

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

This... Lightning rod, is it considered an electrical appliance?

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

In an instant, Xu Xin didn't feel that the lightning rod was useless.

This is a thunderstorm charger!

But...there is only this one production item on the list, and there are no other electrical appliances, and there is no device for storing electricity. This...at this stage, it really has no other use except for lightning protection.

But it can be regarded as timely rain, after all, the rainy season is coming soon.

"Why are there no other electrical appliances? Do you still need copper ore 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 screen: "How is it? What kind of electrical appliances can we make, can we finally have electricity?"

"I'm disappointed." Xu Xin returned to the screen and spread her hands helplessly, "It seems that the electrical appliances need other metals to be unlocked, and only lightning rods can be made in the crafting table. Category."

"Ah~ I'm so happy, I've been paying attention to copper mines, but I haven't found them yet. But lightning rods are also fine, and the rainy season is coming soon. How many black gold nuggets are needed to make it, I'll give it to you!"

"It takes five black gold nuggets to make one, and you give me ten." Xu Xin did the calculation clearly.

"Ah? So many? Didn't you lie to me to cheat me?" Li Wenxi looked at Xu Xin suspiciously, and then persuaded Xu Xin earnestly, "Actually, you don't have to cheat me, as long as you make me a copy." , use whatever you want."

"Who cheated on you." Xu Xin gave her an annoyed look, and sent the attribute of [Lightning Rod] to her, "See for yourself."

"I really need so much..." Li Wenxi rubbed her head in embarrassment, "Then wait a minute, let me 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 Time to have means of transportation."

"..." Xu Xin tried his best not to brag about his silver king to her, he was afraid that Li Wenxi would feel unbalanced. Fortunately, Silver King usually rests in a corner, so he can't see it from the angle of the screen video.

"Wait a minute, enough is enough, the refining is very slow, so wait. Or you make me a crafting table? Then I can make it myself."

"You haven't unlocked the production blueprint, and you can't use the production table if you are given it."

"What you said makes sense, let's forget it first. I will give you the black gold nugget in two hours."

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

"Oh good, by the way, I didn't pay attention just now, you decorated the tree house very nicely, amazing!"

"Ha, you can't always live in such a rough way."

After hanging up the video, Xu Xin immediately made two blue-level heavy crossbows made of special materials and one normal blue-level heavy crossbow, and placed them in the other three directions, so that the attack range of the heavy crossbow can be It covers 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 below the canopy of the tree house, 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 canopy, and then attack with a crossbow or a sharp spear.

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

Next, Xu Xin had to decide on an important matter.

Whether or not to give Silver King a mutation potion to turn him into a mutant creature.
