Su Heng is worried about what to do with these spicy cold rabbits in her hands. Since she wants it, give it to her.

After the transaction was completed, Su Heng continued to browse the information of the exchange.

【Seller: Qi Yulong】

[Items on the shelf: 2 units of high-grade iron blocks]

【Transaction Intention: 1000ml pure water/2kg food】

[Remarks: The unique high-level materials, just opened from the silver treasure chest, can be replaced with materials of the same level, liars don’t come to scold them]

Advanced material? !

This was the first time Su Heng saw high-level materials on the exchange, and he was inexplicably ecstatic.

"You must take it!"

Su Heng directly clicked on Qi Yulong's avatar to start a private chat: "Brother, are you there?"

Qi Yulong: "Yes."

Su Heng: "Sincerely, what is the lowest price?"

Qi Yulong: "That's the price... Wait, are you Su Heng?"

The next second, Qi Yulong changed the price to [2000ml pure water, 5kg food]

Su Heng didn't want to negotiate the price, because high-grade materials were extremely rare.

Unexpectedly, after Qi Yulong saw his identity, he sat on the ground and raised the price!

Su Heng felt a little uncomfortable in his heart.

It's true that I understand watching people play dishes.

Su Heng: "Brother, didn't you do that?"

Qi Yulong: "What happened to me?"

Su Heng: "If you change to the original price, I can trade with you, but this price is a bit expensive."

Qi Yulong: "I can't change it!"

Qi Yulong: "I set the price wrong just now. It's not the price you saw at all."

Qi Yulong: "Little Brother Su, I can tell you that this is the only high-level material on the exchange. Look where there are high-level materials on the shelves now? There are very few intermediate materials."

Qi Yulong is sure, Su Heng wants to get the advanced materials!

Fighting local tyrants didn't do that.

He has doubled the original price!

Qi Yulong: "How about little brother Su, you can think about it.

Qi Yulong: "If you change it, then I won't talk to anyone else, you can just shoot it."

Su Heng carefully calculated the supplies in his hand.

Enough is definitely enough.

But Su Heng would never be used to this kind of person.

If this hole is opened, then he will not be able to get along in the exchange in the future.

Everyone has to raise the price when they see him, so how can he bear it?

Su Heng firmly refused: "No, you sell it."

Qi Yulong: "Okay, then don't regret it, now seven or eight people have chatted with me privately."

Su Heng did not reply to Qi Yulong again.

This guy loves to sell to whom.

Anyway, he wouldn't be the scapegoat.

Materials currently acquired:

2 units of intermediate wood.

1 unit of intermediate steel plate.

1 unit of intermediate nylon.

The materials in hand are enough to make a weapon with strong lethality.

"What are you doing?"

Su Heng calculated it carefully.

"With my fighting power, it's impossible to fight meleely with a 2-star alien beast."

"It's very cost-effective to build a long-range weapon."

Su Heng looked at the [Manufacturing] column, mainly looking at weapons with long-range attack capabilities.

[Compound Bow]

[Materials Required: 2/1 Intermediate Wood, 1/1 Intermediate Nylon]

Crafting a bow and arrow consumes less materials.

When Su Heng was a child, he repeatedly watched the first drop of blood, and Rambo was better than AK at playing the bow.

At least practice hard, the upper limit of that bow will be extremely high.

Su Heng is not a Rambo, and the doomsday world is not a place for Su Heng to practice and be handsome.

His physical fitness is good, but for this traditional straight-drawing bow, one stone is 120 pounds, which requires high physical fitness and skills.

Continue to look down.

[Powerful Composite Hand Crossbow]

[Materials required: 2/2 intermediate wood, 1/1 intermediate steel, 1/1 intermediate nylon]

"Just enough?"

"That's it!"

Confirm the manufacture!

[Powerful Composite Hand Crossbow]

[Quality: Superior]

[Grade: Advanced]

[Evaluation: The whole body of this item combines wood and steel, which not only has lightness and flexibility, but also ensures its reliable performance. It is your faithful partner in the apocalypse! ]

The weight of the composite hand crossbow is almost half that of a chainsaw, and it is easy to hold alone.

Su Heng is mainly interested in its manual winding function, and the requirements for physical strength and skills are very low.

As long as the string is wound, aim at the target.

With a swish sound, it can be launched.

After the item is manufactured, there are a total of 6 matching crossbow arrows.

Su Heng took it in his hand and was eager to try it.

Wind the strings and aim at the wooden table.

"Whoosh!"

boom.

The crossbow arrow was ruthlessly embedded on the table.

Although there is no penetration, the power is extremely high.

Su Heng pulled out the crossbow arrow from the table and commented, "It should be no problem to shoot through the human body."

Su Heng experimented and found that each arrow can be shot at least 20 times before there is a slight loss.

With long-range weapons, Su Heng still lacks a defensive weapon for close combat.

"Daggers are pretty good."

Advanced daggers are generally made of steel combined with other materials.

Su Heng had already swept away the intermediate materials of the exchange, and Su Heng could only use the common class first.

"Anyway, we can take the upgrade route."

"A little bit at a time, it's better than nothing."

Su Heng went to the exchange to collect some steel plates and made a dagger.

[Silver Dagger]

[Quality: Lower Level]

[Grade: Normal]

[Evaluation: Do you need me to shave your face? ]

The quality of the silver light dagger was poor, and Su Heng felt that it was okay to deal with humans.

If you are faced with a 2-star alien beast with rough skin and thick flesh, it is really like the evaluation, it is scraping. UU Reading www.uukanshu.com

But now the guy at hand is complete.

"correct!"

Su Heng slapped his forehead abruptly.

Firewood and coal are not enough.

You have to build a stove that can heat and exhaust smoke.

Otherwise, if the light burned on the floor, Su Heng felt that he would be poisoned by carbon monoxide in a short time.

[Traditional coal stove]

[Required material: 0/30 iron block]

[chimney]

[Material required per 5m: 0/1 aluminum block]

Su Heng checked the layout of the safe house. The coal stove can be placed in the corner next to the table, preferably away from the bed.

Determine the location of the placement, make a rough calculation, it is about 18m.

However, it is too stupid to build just the right chimney.

Once the coal stove is on fire, it will start to smoke outside.

If the chimney was just placed outside, wouldn't it be obvious to others that Su Heng's safe house was underground?

Su Heng went out to check the terrain and found a top-secret chimney location.

It takes about 18m.

"That's 30 units of iron and 4 units of aluminum."

Su Heng immediately posted two trading posts.
