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 vein first."

After that, the group walked towards the not far away from the iron-eating beast cave.

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

Now that he was close, the scene in front of him made Zhang Chi gasp.

On the side slope of the iron-eating beast cave, a small part of the slope was full of rust red.

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

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

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

Ordinary, high-quality, ordinary, excellent.

In a whole mine, the proportion of ordinary grade is not the highest.

The largest number is actually high-quality, followed by ordinary, and even excellent grades.

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

How much wealth will this be sold for!

Thinking of this, Zhang Chi couldn't help but want to take all the iron ores in front of him.

But this idea was forcibly suppressed by Zhang Chi as soon as it arose.

With Lin Tiannan, there are plenty of opportunities to get this kind of vein, so he doesn't need to do such a thing of killing the chicken to get the eggs.

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

"Where is the excellent vein you mentioned?

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

Lin Tiannan had been here a long time ago and had seen the iron ores here, so he was not surprised by the amount of these iron ores.

Hearing Zhang Chi's question, he nodded and stretched out his hand to point to the position above the center of the vein.

"It should be at this location. It's not buried too deep, otherwise it wouldn't form an open-pit iron ore.

You should be able to find it if you dig a few meters down.

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

Zhang Chi nodded, took out the fine-grade pickaxe from his satchel, and came to the location pointed by Lin Tiannan after a few jumps.

After confirming with Lin Tiannan, Zhang Chi carefully dug down.

Because he was afraid of damaging the vein, he didn't use much force each time.

But not long after digging, he began to use all his strength.

There was no way. At the beginning, this was only fine-grade iron ore, and Zhang Chi could still dig with less force.

But the iron ore deep inside was excellent grade. Even if he was excellent grade and holding an excellent-grade pickaxe, he still needed to go all out to dig out a piece.

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

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

Although this is an excellent-grade iron ore vein, the 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 dig around and dig the whole vein, including the surrounding excellent iron ore.

After figuring this out, Zhang Chi's speed became faster and faster, and it didn't take long for him to dig out the whole vein.

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

Identification.

[Iron vein

Grade: Excellent

Effect: Produces iron ore (current excellent grade: 0.1/day, fine: 0.9/day, the rest is omitted.)

Evaluation: A relatively common vein, but its grade is unexpectedly high. Due to insufficient energy, it will produce low-grade iron ore, and it can increase output in places with rich gold energy. ]

Looking at the vein in front of him that is more than ten meters long and wrapped in excellent iron ore.

Zhang Chi estimated that the bag should be able to barely fit it.

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

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

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

You see..."

After saying this, Zhang Chi couldn't help feeling guilty. After all, if he insisted on digging, he could actually dig most of it.

He had just dug a lot, and even dug into the vein part, so he could do it now.

If you really want to be serious, at least hundreds of units of excellent iron ore can be dug.

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

This is not a small amount. If it is converted into excellent iron ore, it must be at least 1,500 units.

Who makes excellent resources extremely scarce now?

He didn't want to default on his debt, but excellent iron ore was too difficult to dig.

If he forced 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 ores for Lin Tiannan, he saw Lin Tiannan nodded and said:

"Okay, but I won't give it to you for free."

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

Is he planning to trade with him using these ores?

"I want to exchange these ores with you for two Qingwu fruits."

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

There is no problem with Qingwu fruits, as he has five in his hand.

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

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

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

But for him who has an excellent synthesis room, it is only worth 10 units of excellent grade.

The value of Qingwu fruit is higher.

Although the number of excellent grade survivors is increasing, the price of Qingwu fruit is rising instead of falling.

After all, most survivors didn't have much sense of excellent grade before, but it was different after the people they knew broke through.

Scroll is the text engraved in the bottom layer of human genes.

Now one Qingwu fruit can be exchanged for at least 250 units of excellent grade steel ingots.

Two pieces are 500 units, and after synthesis, there can be 50 units of excellent grade steel ingots.

You know, this refers to the steel ingot after smelting, not the 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 the cost a lot.

So this deal is not cost-effective for him.

To be honest, Zhang Chi is definitely the most cost-effective to exchange excellent grade and ordinary grade ore.

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 is too great. Even with the three synthesis rooms at full capacity, it is still difficult to gather enough basic materials for his level 4 shelter in a short time.

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

The synthesis room is simply too busy.

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

So he said:

"If you want Qingwu fruit, use fine grade iron ore to exchange with me, forget about these excellent grade, I will give them to you when I return to the shelter."

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

But he didn't ask more questions, and nodded to indicate that he agreed.

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

I'll give you all my half, which should be enough to exchange for two Qingwu fruits, right?"
