Li Xiya quickly walked to the stone storage box, rummaged through, and found that the only thing needed to upgrade the shelter was [Lens x90] [Black Lens x7].

There are only 19 healing mushrooms left, but there are still 30 bottles of Yuehua Elixir, Li Xiya pondered for a moment, took out the resources and put them on the [trading platform].

[Seller: Li Xiya]

【Sale: Healing Mushroom x1】

[Unit price: lens x5]

[Inventory: Healing Mushroom x19]

[Note: Enemy tide countdown, don't want to die at a speed!] 】

This time, the ratio of healing mushrooms to lenses has reached a record high.

Players are helpless when they see this, although players have explored the forest and found a lot of healing mushrooms, but the harvest cannot catch up with the consumption.

During this time, the total amount of healing mushrooms sold in the [Trading Platform] has not exceeded eight thousand, and the price is too low, and other players are willing to keep it in their hands.

Now that it has caught up with the tide of enemies, the scarcity of healing mushrooms has been greatly improved, and Li Xiya is not the only one who has increased the price, it is the current price in the market!

That's it, how many people can't buy it if they want to!

【Successfully sell Healing Mushroom x1, get Lens x5】

In less than a minute, all the healing mushrooms that had just hit the shelves were sold out.

Li Xiya then took out the Yuehua Elixir and put it on the [trading platform].

[Seller: Li Xiya]

【Sale: Yuehua Elixir x1】

[Unit price: black lens x3]

[Inventory: Yuehua Elixir x3]

[Note: A life recovery potion that is stronger than healing mushrooms, instantly restores 20 HP, and the speed you want!] 】

Although the enemy tide counts down, it is a constant reminder that danger is imminent.

However, there are still many players who are active in the regional channels, trying to use chat to relieve their tension.

At this juncture, Li Xiya's listing of goods in exchange for resources has also attracted the attention of many people.

[Prince]: Li Xiya made another move today, it seems that he wants to be promoted to the Bronze Shelter, right?!

[Pang Qingshan]: His speed is so fast!

[Pang Qingshan]: It seems that the treasure chest reward for upgrading the shelter this time is also someone else's!

The two well-known bigwigs of the 9527 regional channel are sighing for a long time.

[Fang Jiana]: Xiya Boss's store is new, you see-[Yuehua Elixir (click for details)]

I don't know if I don't see it, and I'm shocked when I see it!

The Yuehua Elixir is much worse than the weak healing elixir, but the Yuehua Elixir is much stronger than the most mainstream healing mushrooms on the market at present!

The hearts of the players were immediately excited.

[Prince]: @房嘉纳兄弟, the [trading platform] is out of stock, do you sell this bottle? I pay a high price!

[Pang Qingshan]: @李西涯, big guy Xiya, is there still Yuehua Elixir? You say a price, I will never bargain!

[Guan Tao]: Yuehua Elixir? If the big guy in Xiya is not a hit, he is already a blockbuster!

【……】

Seeing that @李西亚 has been fruitless many times, many people can only submit friend applications in private.

【Successfully sell Yuehua Elixir x1 to obtain Black Lens x3】

Inside the shelter.

Li Xiya listened to the almost overlapping prompts, and his face was filled with a smile of relief.

Everyone is very knowledgeable, and Yuehua medicine is not worried about selling.

In the future, the shelter will have another way to make money!

Li Xiya took out the resources from the core of the shelter.

[Copper Shelter Upgrade Requirements: Copper Bar x500, Lens x150, Black Lens x10 (Upgrade duration 3 hours)]

[Consumption of materials to upgrade: Yes/No]

Li Xiya said loudly:

"Yes!"

In the gap between waiting for the upgrade, messages kept coming from the friend channel, and Li Xiya ignored these friend applications.

At present, the inventory of healing mushrooms has been emptied, and the inventory of Yuehua Elixir is limited.

He didn't want to waste too much time with players who didn't cross paths at this juncture.

Even if the inventory of Yuehua potions is limited, it must satisfy old friends first!

[Guan Tao]: Xiya boss, I upgraded the stone shelter before, and I have only scraped together enough resources in the last two days, do you think the cactus armor set is still there?

[Li Xiya]: Guan Tao, I have always kept that set, what resources do you plan to exchange it for?

[Guan Tao]: Thank you, big guy, I'll exchange it for wood.

[Li Xiya]: The price of the cactus armor set is [Wood x1500], according to the previous agreement, you will get a 7% discount on this set, I will wipe it again, just give me [Wood x1000]!

Guan Tao was immediately grateful when he heard this, and hurriedly completed the transaction through the friend transaction function.

With the Cactus armor set, her combat power has increased, and her odds of surviving tonight have been greatly enhanced.

Although Guan Tao's strength is low, she is a person who knows how to repay her kindness, and after looking at the brown potion in her backpack, she gritted her teeth and made up her mind.

[Guan Tao]: Xiya boss, when I was chatting on the regional channel, I saw other players say that you are going to upgrade the copper shelter?

[Li Xiya]: Hahaha, they are well-informed, yes, what's wrong?

[Guan Tao]: Wouldn't it be dangerous to upgrade the shelter with a wave of enemies soon?

[Guan Tao]: The big guy in Xiya has taken care of me during this time, and this bottle of medicine will be given to you.

Li Xiya raised his brows slightly, and took out the potion in the core of the shelter.

【Name:Construction Agent】

[Type: Elixir・Consumption]

[Quality: Normal]

[Effect: Reduced the time to upgrade the shelter building by 3 hours!] 】

[Cooling time: 1/hour]

[Specialization Requirements: General F]

[Note: A single shelter building can only be used once for a single upgrade!] 】

At present, the big guys are in a race against time, although the defense of the shelter is solid, but if you can complete the upgrade of the shelter before the enemy tide starts.

Li Xiya will be able to take the lead in making a series of copper equipment, and his combat effectiveness can also be further improved.

Thinking of this, Li Xiya's favorability towards Guan Tao has increased a lot.

After all, in this world, there are not many people who know how to repay the favor!

[Li Xiya]: This bottle of construction potion is really helpful to me, then I'm welcome!

[Guan Tao]; Uh-huh! If I can help the big guy, I'm relieved!

[Li Xiya]: It's going to be a tide of enemies soon, and I'll send you some resources!

Just when Guan Tao was puzzled, her shelter core received 3 bottles of [Yuehua Elixir].

[Guan Tao]: Oops, thank you, big guy!

[Li Xiya]: We are all friends, don't be so polite!

After ending the chat, Li Xiya immediately used the [Construction Potion] on the shelter.

There was a flicker of light, and the shelter in front of him took on a new look.

【Name:Copper Shelter】

[Note: The Bronze Shelter has a layout of two bedrooms, one living room, one kitchen and one bathroom, and the enhancement of defense and fortification values allows players to face the tide of enemies more calmly!] 】

Li Xiya looked at the bronze shelter in front of him, and felt a sense of satisfaction.

At this moment, a system announcement appeared-

[Li Xiya, a player of Regional Channel 9527, took the lead in upgrading the shelter to a level 3 bronze shelter and rewarded platinum treasure chests, so I hope to keep up the good work!] 】

Li Xiya looked up in surprise when he heard this:

"Platinum Chest?!"
