Chapter 34

Although Lin Yifan currently has no evidence, he vaguely feels that it's better not to have too many survivors die in the same area.

If too many die, unexpected situations might occur.

Moreover, it's a matter of humanity; Lin Yifan ultimately still retains his humanity, and given his ability, he still hopes these compatriots can survive as much as possible.

That's precisely why he hasn't yet managed to trade for a Tier‑3 shelter blueprint.

Yet he never expected that a blueprint would actually be delivered to his door.

Moreover, it's a bronze‑grade blueprint, whereas the ones those who previously wanted to trade with him offered were all black‑iron grade.

This shows just how precious this bronze‑grade blueprint is!

Previously, Hong Shaojiang didn't put this blueprint up for auction, probably because he was reluctant to part with it.

Given his strength, upgrading to a tier‑3 shelter is only a matter of time, so naturally he's reluctant to part with this blueprint.

But since he has now produced it, Lin Yifan naturally wants to obtain it, and he immediately sent a message saying:

"I want this blueprint; as long as you trade it to me, I can promise you that no matter how much mint‑based fever reducer your daughter needs, I will brew it into herbal medicine for you."

"Besides mint, I can also give you some toast or buns, and some blueberries; as I know, when someone is sick they should avoid greasy meat, especially after a fever."

"Toast and buns are easier to digest, blueberries are rich in vitamins and have a sweet‑sour taste, making them most suitable for your child's recent meals."

As long as he can obtain the blueprint, Lin Yifan is still willing to pay the price.

Moreover, it's just some toast and blueberries; he currently lacks no food, let alone such ordinary provisions.

Using these items to exchange for supplies is most appropriate.

Meanwhile, Hong Shaojiang was even more grateful, to the point of almost offering to sell himself into servitude to Lin Yifan.

After the trade succeeded, Lin Yifan didn't immediately go upgrade his shelter or open a treasure chest; instead, he first helped Hong Shaojiang brew the medicine.

After brewing the medicine, he steamed two buns, took the remaining bag of toast, and traded them together to Hong Shaojiang.

Only then did he begin researching the upgrade to a tier‑3 shelter.

He looked up at his shelter, and a prompt immediately popped up.

【Rough Wooden Hut (15 sqm)】

But since he had already taken it out, Lin Yifan naturally wanted to get hold of it, and immediately sent a message saying:

(Overall assessment: This is a hut built from raw timber; although the craftsmanship is rough, it provides adequate shelter from wind and rain, and can withstand small‑beast attacks, but please avoid encountering a herd of wild boars—such a small hut cannot withstand them.)

"Besides mint, I can also give you some toast or steamed buns, and I can give you some blueberries; as far as I know, after getting sick one should avoid greasy meat as much as possible, especially after a fever."

"Toast and steamed buns are easier to digest, blueberries contain lots of vitamins and are sweet and sour, making them most suitable for your child to eat recently."

【Black‑Iron Stone Hut Blueprint: 1/1】（You have obtained a Bronze‑grade Shelter Blueprint; would you like to upgrade to a Bronze‑grade shelter？）

Black‑Iron Shelter upgrade requirements:

【Basic Wood 300/362】（Met）

【Basic Stone 500/517】（Met）

After the trade succeeded, Lin Yifan did not immediately go to upgrade the Shelter, nor did he open the Treasure Chest, but first helped Hong Shaoqiang cook the medicine.

After cooking the medicine, he also steamed two steamed buns and took the remaining bag of toast, and together gave them to Hong Shaoqiang in trade.

Bronze‑grade Shelter upgrade requirements:

【Basic Wood 500/362】

【Basic Stone 800/517】

【Basic Clay 400/208】

（Overall evaluation: This is a wooden house built from raw timber; although the craftsmanship is rough, it can certainly block wind and rain, and can also withstand attacks from small wild beasts, but please do not encounter a herd of wild boars! That is not something a little wooden house can block. ）

【Refined Iron 25/30】

(Friendly reminder: Shelters built from higher‑quality blueprints will be sturdier, safer, and more comfortable; if survivors have the means, please construct higher‑quality shelters.)

Lin Yifan looked at the bronze‑grade shelter upgrade requirements and his brow immediately furrowed.

The bronze‑grade shelter's upgrade requirements differ greatly from those of the ordinary black‑iron shelter.

Therefore, the upgrade materials Lin Yifan has prepared are insufficient; the only thing he has in excess is refined iron.

He doesn't know whether this is fortunate or unfortunate.

However, regardless, refined iron is obviously the hardest to find; once you have it, the other materials are relatively easy.

Nowadays, refined iron is no longer lacking; gathering the remaining materials won't be taxing—at most it will just take some time.

Lin Yifan thought for less than three seconds and immediately decided to construct a bronze‑grade tier‑3 shelter.

If there were no choice, it would be fine; but since there is a choice, naturally he opts for the better option.

【Primary Stone 800/517】

【Clay 400/208】

【Primary Pig Iron 100/122】

【Intermediate Cast Iron 25/30】

（Friendly reminder: Shelters built from higher-quality Shelter Blueprint will be sturdier, safer, and more comfortable. If survivors have the conditions, please still build higher-quality shelters! ）

Lin Yifan looked at the Upgrade Condition of the Bronze Level Shelter, and his brows furrowed instantly.

The Upgrade Condition of the Bronze Level Shelter differs greatly from that of an ordinary Black Iron Level Shelter.

So, the upgrade materials Lin Yifan prepared are still insufficient; the only thing that is high enough is actually only intermediate iron lump.

I don't know whether it's fortunate or unfortunate.

However, regardless, intermediate iron lumps are obviously the hardest to find; if this thing can be found, the rest will be simple.

Now, intermediate iron lumps are no longer lacking; gathering the remaining materials won't be tiring at most, just taking some time.

Lin Yifan only thought for less than three seconds before immediately deciding to build a Bronze Grade Three Shelter.

If there's no choice, it's fine; if there is a choice, naturally one should pick the better option.

So, Lin Yifan immediately took down those 【Strong Mosquito Repellent】 used to exchange for 【Blueprint】, and placed another order to exchange for Wood, stone, and Clay.

Never mind, the Blueprint can't be exchanged, but these Basic Supplies are easy to exchange.

In less than 10 minutes, he had exchanged all the Basic Supplies he needed.

Lin Yifan looked at the pile of materials before him, no longer hesitating in the slightest, and immediately began upgrading the Shelter to level three.

A burst of ding-dang sounds!

The original wooden cabin quickly turned into a fortress-like round house built of stone and earth, with iron sheets.

The outer layer of the house is earth and stone, with a thickness of a full forty to fifty centimeters, while the innermost layer is an iron wall about five to six centimeters thick.

I don't know how that little bit of Cast Iron was forged into such a thick iron wall.

But these are not things Lin Yifan needs to worry about; he only needs to know that this Shelter is his!

The Shelter covers an area of about 85 square meters, and inside it is divided into four parts by neat Green Stone Slats.

On the far left is a slightly larger room plus a smaller compartment; the small compartment is only about six or seven square meters.

So Lin Yifan estimates that this is the master bedroom with a bathroom.

Meanwhile, the middle area remains a living room, and on the right is likewise a partitioned compartment where the Operation Platform he previously made is placed.

Obviously this is an operation room.

And on the wall of each space there is a fairly large window, through which one can see the pitch-black world outside.
