Survival: Fighting floods from a thatched hut.

Hearing Lin Tiannan's words, Zhang Chi nodded and put the iron-eating beast into his bag.

"Let's go and check out the situation of the mineral vein first."

After saying that, the group walked towards the nearby iron-eating beast cave.

Because there was a blind spot on the opposite hill, Zhang Chi did not see the iron ore vein.

Now that he had gotten closer, the scene before him made Zhang Chi gasp.

On the side slope of the iron-eating beast's cave, a small half of the slope is full of rust-red.

It turned out to be an open-pit iron mine with huge reserves.

The iron ore reserves here are at least over 50,000 units.

In amazement, Zhang Chi took out his survival manual and identified the ore in front of him.

Ordinary, high quality, ordinary, excellent.

In an entire mineral deposit, the proportion of ordinary grade minerals is not the highest.

The largest number are actually of high-quality grade, followed by ordinary grade, and there are also quite a few of excellent grade.

If all the iron ores were mined and synthesized, Zhang Chi would not only get enough steel ingots to upgrade the shelter to level 4, but also have a large portion left over for refining equipment.

How much fortune would this have to sell for!

Thinking of this, Zhang Chi couldn't help but want to take all the iron ore for himself.

But as soon as this thought arose, Zhang Chi forcibly suppressed it.

With Lin Tiannan around, there are plenty of opportunities to get this kind of mineral vein, so there is no need for him to do such a thing as killing the goose that lays the golden eggs.

The greed in his heart disappeared, Zhang Chi looked at Lin Tiannan beside him and asked:

"Where is the excellent mineral vein you mentioned?

How about I take out the ore vein first, and then dig out the iron ore?"

Lin Tiannan had been here before and had seen the iron mines here, so he was not surprised by the amount of iron ores.

Hearing Zhang Chi's question, he nodded and pointed to the upper center of the vein.

“It should be right here. It’s not buried very deep, otherwise it wouldn’t form an open-pit iron mine.

If you dig a few meters down, you should be able to find it.

But it's better to use less force, otherwise you might damage the root of the mineral vein."

Zhang Chi nodded, took out a high-quality pickaxe from his bag, and after a few jumps he arrived at the location Lin Tiannan pointed to.

After confirming with Lin Tiannan, Zhang Chi dug downwards cautiously.

Because he was afraid of damaging the mineral vein, he did not use much strength each time.

But he didn't dig for long before he started using all his strength.

There was no way. At the beginning, there was only high-grade iron ore here, and it could be mined by exerting some strength.

But the iron ore deep inside is of excellent grade. Even if he is of excellent grade and has an excellent grade pickaxe, he still needs to use all his strength to dig out a piece.

A minute later, Zhang Chi felt that this was not going to work.

If he continued like this, by the end of the digging, it would be difficult for him to control the force just right every time.

Although this is an excellent grade iron ore vein, its hardness may not be higher than that of iron ore. If it is damaged, it will be a big loss.

After a little thought, he decided to simply dig around and dig up the entire vein, including the surrounding excellent-grade iron ore.

After realizing this, Zhang Chi's work became faster and faster, and it didn't take long for him to dig out the entire vein.

He carefully dug out all the excellent grade iron ore in a corner of the vein and saw a little bit of the true appearance of the iron vein.

Identification.

Iron Ore Veins

Grade: Excellent

Effect: Produces iron ore (currently Excellent: 0.1/day, Fine: 0.9/day, others omitted.)

Evaluation: A relatively common mineral vein, but its grade is unexpectedly high. Due to insufficient energy, it will produce low-grade iron ore. In places with rich gold energy, the output can be increased. 】

Looking at the vein in front of me, which is more than ten meters long and surrounded by excellent iron ore.

Zhang Chi estimated that the shoulder bag should be able to hold it.

In other words, he can trade it directly to someone else and take it back when he returns to the shelter.

However, half of the excellent grade iron ore above belongs to Lin Tiannan, so I have to discuss it with him.

"Old Lin, you can see that there is no way to dig out all the iron ore without damaging the vein.

look......"

After saying this, Zhang Chi couldn't help feeling a little guilty. After all, if he really wanted to dig, he could actually dig out most of it.

He had just dug up a lot, and even found part of the mineral vein, so he could naturally do it now.

If you really want to be picky, you can at least dig up hundreds of units of excellent-grade iron ore.

With a 50- split, Lin Tiannan can get nearly units.

This is not a small amount of money. If converted into high-quality iron ore, it would require at least 1,500 units.

Who makes excellent resources extremely scarce nowadays?

It's not that he wants to default on his debt, but the excellent grade iron ore is too difficult to mine.

If he forced himself to finish digging here, he might not be able to return to the shelter before dark today.

Just when Zhang Chi was about to take a step back and increase the share of other quality iron ore for Lin Tiannan, he saw Lin Tiannan nodded and said:

"Okay, but I'm not giving it to you for nothing."

Hearing this, Zhang Chi was surprised for a moment, but he quickly reacted.

Are you planning to trade these minerals with him?

"I want to exchange these ores with you for two Green Mist Fruits."

Hearing this, Zhang Chi weighed the pros and cons in his mind.

There is no problem with the Qingwu Fruit, as I have five of them in my hand.

After handing the Qingwu fruit tree to Qian Zhongtian, he had already ripened it.

There were six Qingwu fruits. Zhang Chi took three and gave the rest to Qian Zhongtian for breeding research.

For others, 1 unit of excellent-grade iron ore can be exchanged for more than 30 units of fine-grade iron ore.

But for him who owns an excellent-level synthesis room, it is only worth 10 units of excellent level.

The value of Qingwu Fruit is very high.

Although the number of high-quality survivors is increasing, the price of Qingwu Fruit is rising instead of falling.

After all, most survivors didn’t have much of a sense of the premium level before, but it became different after someone they knew made a breakthrough.

Volume is the text engraved in the bottom of human genes.

Now, one Green Mist Fruit can at least be exchanged for 250 units of high-quality steel ingots.

Two pieces equal 500 units, and after synthesis, you can get 50 units of excellent-grade steel ingots.

You should know that this refers to smelted steel ingots, not unprocessed iron ore.

Iron ore needs to be smelted before it can become iron blocks and steel ingots.

There will be about half of the consumption in the middle.

In addition, steelmaking also requires charcoal of the same grade, which will also increase costs significantly.

Therefore, this deal is not a good deal for him.

To be honest, it is definitely the most cost-effective for Zhang Chi to exchange high-quality and ordinary-grade ores.

After all, the current market price of iron ore with a one-grade difference is not as cheap as 10:1.

However, his demand for high-quality materials was too great, and even with three synthesis rooms running at full capacity, it was still difficult to gather the basic materials for upgrading his shelter to level 4 in a short period of time.

Besides the shelter, the automated workshop also needs a large amount of steel ingots.

The synthesis room is simply overwhelmed.

So he planned to switch to fine grade and use his own steelmaking furnace to directly smelt fine grade iron ore to reduce some of the pressure in the synthesis room.

So he spoke:

"If you want the Green Mist Fruit, you can exchange it with me for the Excellent-grade Iron Ore. Forget about these Excellent-grade ones. I'll give them to you when I return to the shelter."

Hearing this, Lin Tiannan was a little surprised. He had calculated that the price of trading these excellent grade ores was higher than the market price.

But he didn't ask any more questions and just nodded to indicate his agreement.

“The fine-grade iron ore here is about 3,000 units.

I'll give you my half, that should be enough to exchange for two Green Mist Fruits, right?"
