"A thousand copies of diorite? That much?"

When Fang Yu heard that Chen Changan needed diorite, he didn't take it to heart. Although it is more difficult to mine than iron ore, it is more abundant!

"What? Can't you get it together?" Chen Changan asked.

"No, no, we can get it together, but... we may need to replace some green crystals. This diorite is more difficult to mine than iron ore!" Fang Yu said tentatively.

"That's natural, you should make a price first!" Chen Changan nodded.

Now, besides food and water, what Chen Changan owns most is green crystal.

However, this is a crystal that can only be dropped by a third-level ferocious beast. Even if he has a lot of it, Chen Changan will not squander it wantonly.

He made a rough estimate, exchanging one emerald for one hundred parts of diorite, it shouldn't be a loss!

So his bottom line is ten green crystals. If there are more, then ask Zhang Yao!

"Well, how about five green crystal stones? I'll get them all for you within ten hours!"

"Five?" Chen Changan was stunned, but he didn't expect it to be so cheap.

"No, three!"

After a while, Chen Changan replied with four words.

"Brother Chen... I know this green crystal is very rare, but... this diorite is not that easy to mine, and you want a thousand copies..." Fang Yu was a little embarrassed.

"Let's do this. We have known each other for such a long time. Let's each take a step back and give you four pieces of green crystal. If it still doesn't work, I will find another seller!"

Chen Changan said unhurriedly.

"Okay, then four green crystal stones!" Fang Yu gritted his teeth and responded.

"Contact me when you have collected enough!"

Diorite is a fully crystalline neutral plutonic rock and one of the main rock types in granite stone.

One part bluestone brick requires two parts diorite and two parts diabase!

Upgrading the level 3 safe house requires 500 bluestone bricks, which Chen Changan mined himself, which would take at least dozens of hours.

With a lot of resources in his hands, he naturally doesn't need to work so hard to mine.

When looking for the bones and meat of third-grade ferocious beasts at the exchange, Chen Changan paid attention to diorite and diabase, but there was no news of any sale.

Judging from this, there may not be so many people discovering the function of this rock now, let alone hoarding it!

All we can do is find a larger camp to help Chen Changan collect, so that the speed can be much faster.

Although Fang Yu did not indicate that he was from a certain camp, Chen Changan was certain that Fang Yu had joined a camp and had extremely high power within the camp.

Now you need two copies of ore, and it is best to collect them in two groups of people to maximize efficiency.

After closing the dialog box with Fang Yu, Chen Changan directly sent an illustrated guide to Zhang Yao.

The picture book shows a large repeating crossbow that is placed on the ground. It is the [Migratory Locust Repeating Crossbow] that Chen Changan got from the second-level silver treasure chest!

This repeating crossbow has a strong ability to break through the defense of ferocious beasts below the third level. If it was not too clumsy and his safe house was not afraid of the ferocious beasts of the third level, Chen Changan might keep it by himself.

"Brother Chen, what are your orders?"

Normally, the messages sent by Chen Changan to Zhang Yao are replied within seconds.

"Battle Commander Zhang is joking, but I don't dare to obey his orders!"

"What do you think of this weapon?"

"Brother Chen...don't you want to trade this weapon?"

Zhang Yao was a little surprised. This repeating crossbow looked a bit clumsy, but just because it could break through the defenses of ferocious beasts below the third level, it was definitely an artifact for guarding the home!

Especially now that the camp is gradually expanding, the possibility of being attacked by ferocious beasts has increased several times. Zhang Yao is worried that he has no weapons to defend the camp!

Her first reaction when she saw the Locust Liannu was that Chen Changan might want to sell it to her.

But Zhang Yao would never take action on such a life-saving artifact!

Of course, Chen Changan is not Zhang Yao. The Liuyun Bow in his hand can break through the defenses of most third-grade ferocious beasts with only green crystals, and can break through the defense of fourth-grade ferocious beasts at most.

In addition, Chen Changan's two battle beasts can also defeat a group of third-level ferocious beasts.

Therefore, this "clumsy" repeating crossbow is not of great use to him. It is better to sell it at a high price when no one has any better weapons!

"Can you get some diabase?"

Chen Changan asked straight to the point.

"Diabase... there is this one not far from my camp. It was mined before. I originally planned to build a city wall outside the camp, but the project was too huge, so it was postponed!"

"I need some diabase!"

"This is easy to handle. How much does Brother Chen need?"

There are more than a hundred copies of diabase in the warehouse of Zhang Yao's camp!

In the early stage, apart from the need for more wood, the demand for this kind of ore is relatively small, and there are only about a few dozen general construction drawings.

"I want a thousand copies."

"You didn't ask...a thousand copies?" Zhang Yao was about to agree, but was stunned for a moment.

Zhang Yao wouldn't be surprised even if it was four to five hundred copies. This was a thousand copies.

Even if more than 70% of the people in the camp are mobilized, it may take more than ten hours!

"What? Is there a problem?" Chen Changan asked.

"No, no problem. Brother Chen, do you want to exchange this repeating crossbow for a thousand diabase rocks?"

"Isn't it enough?"

"It's not that it's not enough, it's that I feel like Brother Chen has suffered a bit!"

"Um... do you have the bones and skins of third-grade ferocious beasts?"

"Yes, how much does it cost, Brother Chen?"

Originally, Zhang Yao's camp did not have these things, but the newly merged camp had killed several third-grade low-level ferocious beasts in the past, and now these animal bones and skins are stored in the camp warehouse.

"Twenty parts of animal bones, ten parts of animal skins!"

"Okay, wait until I send someone to get it, and then trade it with the diabase for you!"

"By the way, I have a weapon. I can't use it for the moment, so I'll give it to you for self-defense!"

"Self-defense... weapons?" Zhang Yao's heart moved.

She also has small self-defense weapons, but they can only withstand first-class ferocious beasts at most.

Chen Changan traded his psychic crossbow to Zhang Yao, but Xin Yue did not take it with her when she left.

The beasts he was facing now were all third-grade or above ferocious beasts, and he had no need for this one. He originally planned to exchange it for some beast bones, but now he traded it directly to Zhang Yao.

Exchanging a locust repeating crossbow for a thousand diabases was beyond Chen Changan's budget, and with the addition of animal bones and skins, he felt that he had taken advantage of it a bit.

Of course, there is no problem if it is a one-time deal, but if you want to cooperate for a long time, it is best if everyone does not owe each other.

After the transaction, the two exchanged pleasantries before Chen Changan closed the chat dialog box.

He now has all the materials to upgrade the safe house. He just needs to wait a dozen hours to trade with Zhang Yao and Fang Yu respectively.

Chen Changan walked slowly to the Qingyu Cold Iron storage box and took out the bottle of [Spiritual Enlightenment Liquid].

"The second volume of the Beast Controlling Technique, with a breakthrough to the third level, can instantly pull the beast control master to the designated battle beast. As the strength of the battle beast increases, the distance can be increased!"

This is similar to the traction skill in the first volume. Although it does not provide a shield, it is still a very powerful life-saving skill!

"It's quite sweet, a bit like...peach juice?"

Chen Changan poured the liquid in the bottle directly into his mouth and smacked his lips slowly, as if he was still unfinished.

"I have all the toilet paper ready this time. It will never be like last time..."

"Gululu!"

Chen Changan's stomach made a sound, and an overwhelming feeling came over him.

"Bang!"

Chen Changan opened the door forcefully and ran out in embarrassment.

"It's broken, it's too late!"

"Next time you have to do it in the toilet!"

Chen Changan rushed to the toilet before he collapsed.

"Woo~~"
Chapter completed!
