Survival in the wilderness: I have an RV to upgrade everything

After the successful transaction, Lin Nan got the blueprint with satisfaction.

Li Yanzu: "Brother, are you the legendary Nanshen?"

Lin Nan: "I'm not Nan Shen, but a male god."

Li Yanzu: "...Brother, are you that great god who trades mineral water for coarse cloth?"

Lin Nan: "That's right, it's me."

Li Yanzu: "Nan Shen, can you tell me what you want this rocket graph paper for? Could it be that you have already obtained a peerless weapon?"

Lin Nan: "Xiaozu, listen to my uncle's advice, you are still young, ask about what you should inquire about, and don't inquire about what you shouldn't, the water in this world is very deep, you can't grasp it!"

Li Yanzu: "..."

……

Looking at the blueprint in his hand, Lin Nan was thinking again about the chicken or the egg... Uh no, upgrade the blueprint first or make the item first.

After thinking about it for a while, I decided to make the rocket and then upgrade it.

Because he saw two familiar things on this blueprint.

【Rocket arrow production blueprint (excellent)】

[Materials required: Wood*1, Flint*1, Iron Ingot*1]

He already has wood and flint, and as long as he finds another iron ingot, he can make rockets.

It's time to upgrade again, I'm so happy!

So he opened the exchange again and searched for iron ingots inside.

Turns out, not at all!
It seems that iron ingots are relatively rare, and no one has found them yet.

Or, even if you find it, you may not be interested in it.

This thing can't be eaten, and it can't be drunk. If you take it, it still takes up the space in the warehouse.

You know, except for Lin Nan, it is estimated that the warehouses of most people are still 10 grids.

Rely on parents at home, what to rely on when going out?
friend!

Lin Nan clicked on the friend column and found that there was only a single name in it:
Liu Jingxue.

Lin Nan: (×_×;)
Next time, I must make a few more friends. Even if I don’t plan to go with them, I usually exchange some items, and it’s okay to exchange things.

Lin Nan: "Hello, I want to ask, do you have any iron ingots?"

Soon, Liu Jingxue responded with a message.

"some."

Lin Nan: "It's true, you're lucky that the needle doesn't poke!"

Liu Jingxue: "Where do I have any luck? If I had any, I wouldn't be so hungry and cold like I am now."

Lin Nan: "Don't you have any clothes to wear?"

Liu Jingxue: "Your focus is a bit strange. Of course I have clothes, but they are a little thinner. The main reason is that I don't have food and water."

Lin Nan: "Oh, so it is like this, you give me the iron ingot, and I will give you food and water."

Liu Jingxue: "Okay, I'm planning to hang this iron ingot on the exchange for some food, but I'm not sure if anyone will want it."

As she spoke, she sent a transaction request.

Lin Nan decisively agreed.

After the trading box appeared, the other party immediately put the iron ingot in the trading box.

Lin Nan knew that Liu Jingxue was straightforward, which was one of the reasons why he agreed to her friend application.

Communicating with her is very worry-free and trouble-free.

As for other reasons, there are also, but it is definitely not because she is a big beauty!
She didn't say how much food and water she wanted, but Lin Nan must not be stingy at this time!

Firstly, because Liu Jingxue really helped him a lot, she gave him the Bow and Crossbow specialization skill book, as well as the coarse cloth he urgently needed, and now it is iron ingots.

If it weren't for the Bow and Crossbow Specialization, maybe he would have given it to the big black bear.

She is simply her own timely rain!

Second, now that she lacks food and water, her life may be in danger.

In case of any accident, Lin Nan would lose a source of supplies.

Thinking of this, he put 5 pieces of buttered bread, 2 liters of Evian mineral water and 10 cherries.

Distressed, there must be a little bit, but if it is regarded as an investment, then it will be fine.

Anyway, most of these things come from system upgrades, and there will definitely be more in the future.

As long as you pay more attention to the exchange and exchange some low-level water and food at the same value, these things will definitely continue in the future, so there is no need to worry at all.

Liu Jingxue: "Σ(ω) is too much, no, no, no, you will be at a disadvantage!"

Lin Nan: "You may make a small profit, but I will never lose money!"

Liu Jingxue: "Σ( ˙˙ )!?"

Lin Nan: "Ahem...I mean, this iron ingot may be useless to you, but it is very useful to me, and I feel that I gave you less and took advantage of you."

Liu Jingxue: "What nonsense are you talking about, what do you mean taking advantage of me!"

Lin Nan: "..."

Liu Jingxue: "By the way, it's convenient to disclose, what is this iron ingot used for? Don't get me wrong, I'm just curious."

Lin Nan: "Sorry, this is temporarily kept secret."

Liu Jingxue: "Alright."

She clicks Agree to the transaction.

After Lin Nan also agreed, a silver-white iron ingot entered the warehouse.

Maybe he felt embarrassed, or the way he refused her to inquire about the purpose of the iron ingot just now was a bit unreasonable.

Lin Nan sent another message: "Beauty, I want to buy you a cup of coffee."

Liu Jingxue: "Ah... Lin Nan, we are in a precarious world right now. No one knows what will happen tomorrow. We may starve to death or be killed by wild animals, so I won't think about that aspect for the time being. I hope You can understand."

Lin Nan: "Uh, you may have misunderstood."

After finishing speaking, Lin Nan sent a transaction application.

Liu Jingxue quickly agreed.

It may be that the trust in Lin Nan has increased after trading several times.

Lin Nan put on 500ml of freshly ground Blue Mountain coffee, and agreed.

There is nothing in the transaction column of the other party, which means that it must be given to the other party.

Liu Jingxue: "Is this for me?"

Lin Nan: "Yes, I just opened a treasure chest and got a lot of this kind of coffee. It can boost your energy, which means it can save you time to sleep."

Liu Jingxue didn't hesitate, and directly agreed.

Liu Jingxue: "Then thank you, I owe you another favor."

Lin Nan: "Don't be so polite, let's help each other! In the future, if you have any good things, we can trade them at any time, or if you need anything, you can always come to me!"

Liu Jingxue: "Yeah!"

After finishing the chat, the first thing Lin Nan did was to throw the iron ingot into the trunk.

"System prompt: Are you sure to confirm the upgrade?"

"confirm!"

"The upgrade was successful! [Iron Ingot (Normal)*1] was upgraded to [Iron Ingot (Normal)*20!]"

One piece becomes 20 yuan, the robbery is not so fast!

Lin Nan touched the uniform 20 yuan iron ingots exuding silver-white light, and then happily took out the rocket diagram paper.
