In the final analysis, the reason why pyroxene has attracted the attention of many forces is because it has the possibility of becoming a strategic resource and changing the power pattern between countries.

But on the other hand, whether pyroxene can become a strategic resource ultimately depends on its output and stability.

If pyroxene cannot be stably mass-produced and loses the feasibility of cultivating a large number of low-level martial artists, its importance will plummet in an instant, and it can be regarded as a relatively precious cultivation resource at most.

To be able to make the federal military and the annual ring pay so much attention at the same time, Du Mu and Luo Shen only think about it.

Speaking of which, the name Primordial Pyroxene seems to have a similar meaning in it. Du Mu muttered, "Maybe it's the key to the output of pyroxene!"

"It's very likely!"

Luo Shen nodded slightly, and then showed a hint of regret.

"It's a pity, this time we went to the northern ruins, with our strength, at most we would go around the periphery, it was impossible to find the primordial pyroxene in that kind of place, and even if there were, it would have been searched by the seniors of the third and fourth grades. ”

"And this time it's mostly a squad operation, there are other people, everyone is watching, even if you find the source of the primordial pyroxene, you can't take it away privately, it is said that after walking out of the ruins, you have to go through the military's inspection to make sure that there is no private pyroxene before leaving. ”

Du Mu patted him on the shoulder, "If it is so easy to find the Origin Pyroxene and bring out the ruins, the annual ring will not be rewarded with 300 merit points." ”

"That's right!" Luo Shen smiled dumbly.

"Let's go back to the dorm and see what we have to prepare. ”

"Good. ”

......

Two days passed in a flash.

In the dream, Du Mu still hadn't found the key, and the hundreds of cells in the prison had been searched by him and Xiao Jiu for more than ninety percent, and only the last five were not found.

At their rate, it can all be solved in just one night.

It's a pity that I have to go to the northern ruins next, so I can only put it on hold for the time being.

On the other hand, the Corrupt killed during the search contributed more than 90 Nightmare Energy to Du Mu.

However, he didn't use it to light up the star map.

Considering that Xiao Jiu is still holding a weapon that is about level 4, and the style is relatively special, and it can't be purchased at all in reality, Du Mu simply spent 90 nightmare energy to exchange a weapon for Xiao Jiu on the weapon unlock interface.

'Black Knife Autumn Water: One of the twenty-one works of the Great Quick Knife, from "One Piece" Roronoa Zoro, unlock condition: 90 nightmare energy. ’

The blade of the black knife Qiushui is black and purple, and there is a red zigzag pattern engraved on it, which looks like a strange beauty, which is quite a match with Xiao Jiu.

According to Du Mu's estimate, the Black Knife Qiushui is at least equivalent to a level 6 weapon.

It is worth mentioning that it was not until after unlocking it that he learned from the information in his mind that it turned out to be a weapon called Taidao.

After everything was prepared, early that morning, Du Mu gathered Luo Shen and went to the school gate to gather.

The car had already been prepared at the school gate, including Xia Zhi, and the group got on the train directly after arriving, arrived at the train station, and then changed to the train.

"The destination is a bit far and will not arrive until tomorrow morning. Xia Zhi explained.

The college has a lot of money, and directly wrapped the entire carriage of high-end soft sleepers for the group.

After getting into the car, everyone immediately gathered in the living room to listen to Xia Zhi explain the content of the task to them.

"The area of the northern ruins is very large, and the area that has been discovered so far is no less than one million square meters, and because there are no obvious markers, it is impossible to map in detail, so we can only rely on the terrain to roughly divide into three areas. ”

While speaking, Xia Zhi took a map and spread it out on the coffee table in the middle.

Three ring-shaped areas are outlined with simple lines, marked from the inside to the outside, with the 'core area', 'inner area' and 'outer area' marked in order.

Xia Zhi pointed to the map and said slowly.

"This ruin is a bizarre underground city, with severe desertification, and these three areas are divided according to the degree of desertification, the further you go inside, the more desertification becomes, especially in the core area, which is basically the same as a desert. ”

"In addition, there are a lot of desolate beasts living in the ruins, most of them are fierce-level desolate beasts, and a few barbarian-level desolate beasts will only appear in the core area, as long as you don't get close to there, you don't have to worry about encountering them. ”

"The military has collected a lot of information about the Ruined Desolate Beasts, and when they get to the base there, they will give you a detailed atlas. ”

Everyone nodded slowly.

Like warriors, desolate beasts also have ranks.

Among them, the lowest level is the fierce level, and the upper level is the brute level, and even the taboo level.

However, even the lowest fierce beasts have enough strength to rival martial artists, and the most ferocious ones can even defend themselves against six-star martial artists.

And the barbarian-level fierce beast can only be dealt with by a seven-star martial artist.

As for the taboo level higher, it is beyond the scope of ordinary martial artists, and it requires a higher-level martial artist to contend with it.

"The area where you will carry out the mission in the future is the outer area, and the strongest beast that has been encountered in this area so far is only a three-star level, with your strength, if you form a team to join forces, you should be able to exterminate it, even if you can't kill it, it is not difficult to escape, and if you are cautious, you will not risk your life. ”

"Then what exactly is our mission?" Chi Xiangzhen listened for a long time, and finally couldn't help but ask.

Xia Zhi waved his hand, signaling not to be in a hurry, and then continued: "There are two main contents of the mission!"

"The first item is to search for pyroxene!"

Speaking of this, Xia Zhi took out his mobile phone, and looked up at everyone after some operation.

"Okay, I'll send you the relevant pictures, open your phone and take a look. ”

Du Mu happened to notice that the mobile phone was vibrating, and when he heard this, he immediately took it out and opened the text message sent by Xia Zhi, which had six pictures attached to it.

"These are pictures of pyroxene, you can familiarize yourself with them in advance and keep them in your mind, and when you get to the ruins, it will be very inconvenient to use your mobile phone. ”

Everyone didn't say a word, silently browsing the pictures on their phones.

The shapes of pyroxene are almost identical, the only difference is the light they emit.

Strength pyroxene is crimson, Agility pyroxene is light cyan, Constitution pyroxene is earthy yellow, and Perception Pyroxene and Will Pyroxene are sky blue and cyan purple respectively.

In addition to these five types, there is also a relatively large hedron that is the size of a fist, with a hazy and beautiful silver-white light, and four bold characters are marked in the upper right corner.

Primordial pyroxene!

"After many searches by the third and fourth graders, most of the pyroxene in the outer area has been excavated, and only a few fish have escaped, even so, as long as you can find a place where the pyroxene crystallizes, this mission will be a great harvest. ”

Xia Zhi's words drew everyone's attention back.

"According to the rules negotiated between the academy and the military, half of the pyroxene you obtained in the ruins must be handed over to the military, and the remaining half is your own. ”

"Eh!" Chi Xiang Zhenxiu frowned, dissatisfied, "Why do we have to hand over half of the pyroxene that we desperately found to the military!?"

Xia Zhi smiled dumbly: "After all, the ruins were discovered by the military first, and they also stationed heavy troops on the periphery, which ensures the safety of the rear, so that you can explore without worries, and it is not too much to ask for half of the income ratio, and many people outside have no chance to want it." ”

Chi Xiangzhen pursed his lips, and his dark eyes rolled around his bones.

As if guessing what bad idea she was thinking, Xia Zhi said unhurriedly: "There is a detection equipment set up by the military at the exit of the ruins, which can detect the existence of pyroxene, so it's best not to have a bad idea, lest you steal chickens and rice when you get it." ”

Chi Xiangzhen's expression froze, and his shoulders suddenly collapsed as if deflated.

"In addition, the 50% surrender ratio is only applicable to the first five kinds of pyroxene, except for the primordial pyroxene, no matter how many you find, you must hand over all of them! Once it is found that it is privately hidden, it will directly confiscate all the income of the person concerned, and at worst it will be dealt with by wartime military law, and the consequences will be very serious!"

"No, it won't. Chi Xiangzhen's beautiful eyes widened slightly.

The rest of the people looked at each other in the same way, not understanding why the military had set such a draconian rule.

Only Du Mu and Luo Shen glanced at each other vaguely, their eyes flickering.

"I can't go into detail about the specific reasons for this due to confidentiality regulations. Xia Zhi waved his hand, and then said with a smile, "But as compensation, as long as you find the Origin Pyroxene and hand it over to the military, even if there is only one, the rest of the pyroxene harvested by the person who turned over in the ruins this time will be 100% owned by himself, and the military will no longer extract from it, and even each Origin Pyroxene will be rewarded with an additional 30 other types of pyroxene!"

At this moment, even Lei Kai, who had always been indifferent, couldn't help but show a hint of surprise.

What is the role of this primordial pyroxene, which is worth such a big concession by the military, not to mention giving up 50% of the pyroxene income, and rewarding pyroxene additionally?

And not one or two, but a full 30!

Just when the rest of the people were puzzled, Du Mu took a breath without a trace, and became more and more sure in his heart that the stable output of the primordial pyroxene and pyroxene were related, otherwise the military would not have put on such a eager attitude.

The group of eight people silently digested for a moment, and then Chixiang Zhencai continued to ask, "What about the content of the second task?"

"The second item ......" Xia Zhi pondered for a few seconds, as if he was considering his words, and then asked after a while, "You all know about the Gemological Academy, right?"

Seeing everyone nodding, he continued: "In fact, the location of the northern ruins is a bit delicate, just on the border between the Fire Silver Merchant Alliance and the Federation, so both countries have claimed ownership of the ruins, and a war almost broke out for this. ”

"In the end, after many negotiations, the Federation and the Fire Silver Merchant Alliance decided that the two countries would jointly develop the ruins, and how much they could gain depended on their strength, and the next thing you also know, at the request of the military, the Star Luo Academy recruited three grades of students to enter the ruins. ”

"And on the side of the Huoyin Merchant Alliance, it is the students of the Gem Academy who are dispatched!"
