The box contained a thumb-sized crystal with a royal blue glow throughout, but a greenish core area. It has a faint layer of blood on its exterior.

"Third-Order Yuan Stone?" I don't know who exclaimed.

Only then did everyone wake up.

"No, it's not just the third-order, but the Yuanshi that is evolving into the fourth-order." Someone corrected.

The appearance of this yuan stone suddenly made everyone's eyes converge on the mermaid leader again.

Chen Tianci looked at the third-order Yuan Stone curiously. To be precise, it was a Yuan Stone that was about to enter the fourth order.

This kind of metastone that is about to cross the grade is usually a symptom of the metastone that has survived in the metastone mine for a long time.

Yuanshi is the product of the free vitality in nature, which gradually condenses into one place and appears after many years.

The number of such things is extremely small. But once they converge into groups, metabolite veins emerge.

Once the metastone vein is formed, it will continue to absorb the vitality that is free in nature.

This is also the reason why the Yuanshi mine will continue to produce Yuanshi.

As long as it is not completely excavated at one time, the Yuan Stone Mine will gradually recover itself after a period of cultivation. This is also the reason why once each city-state has a Yuan Stone Mine, it will send heavy troops to guard it.

Chen Tianci also had the news of several Yuanshi veins. But after many investigations by his fleet, it was found that all of them were empty promises issued by Dongfang City at the beginning.

In fact, the news was not pointing to the Yuanshi mine at all, but to some very ordinary mineral veins.

It was only after the destruction of Dongfang City that Chen Tianci's united city-state had its own Yuanshi vein. It was inherited from the eastern city-states, and it had been mined to the recuperation period.

Therefore, he has a certain understanding of this kind of yuan stone.

"Not bad. This metastone is indeed produced in the original metastone veins. Chen Tianci confirmed loudly, "I can confirm this." ”

"How do you know for sure?" Everyone turned their heads to look at Chen Tianci.

"Because I've been in the Yuanshi Mine. I'm familiar with this stuff. Chen Tianci said.

Although his answer was not specific enough, with his strength and current status, it was difficult for everyone to doubt. Because he's the premier master here, he should disdain to lie in his capacity.

The head of the mermaid gave Chen Tianci a grateful look. Chen Tianci This is the second time that he has spoken out to help.

While she was grateful to Chen Tianci, a look of curiosity flashed in her eyes.

Yuanshi Mine is not accessible to ordinary people.

After Chen Tianci finished speaking, he didn't say anything more.

Click to stop, and you're good to go. If he talks too much, it will make people feel that he is encouraging everyone to enter, and if there is any trouble or unpredictable danger in the future, then his responsibility will be much greater.

He didn't want to get himself in trouble.

"Ladies and gentlemen," said the mermaid leader again at this time, "this is the proof I received from the fisherman in the first place. When he was dying, he used this yuan stone as a thank-you gift. Only then did I learn that there was an ownerless Yuanshi mine in this place. ”

Everyone nodded slightly, this time, there were many people who believed.

"Although, I was skeptical at first. But after so much investigation, I also know a little bit about this place. The charts you are seeing now, to tell you the truth, are actually the ones that I have been discovering one after another over the past few years. The mermaid leader explained, pointing to the charts in front of everyone.

Everyone raised their eyebrows and took a closer look at the chart again.

Indeed, the contents of this chart have been stitched together many times. There are a lot of connecting places, and there are some blank spaces. Overall, about 40 percent of the charts are concrete, while half of the remaining 60 percent are vague and approximate, and the other half is completely blank.

And the blank area is precisely the core, which is said to be the area where the Yuanshi mine exists.

"On this map, all the specific contents marked are the results of the previous batch of mercenaries I brought into the exploration in the past few years. Those vague areas are the ones that have been listened to and have not been actually explored. The mermaid captain explained.

Everyone nodded slightly, satisfied with each other's frank attitude.

"Since that's already the case, let's not say anything more. Everyone quickly divided into points, determined the groups, and started to act. Someone suggested.

Everyone agreed.

Subsequently, the group of people was divided into groups. There were seven groups of 10 members each. Chen Tianci was not included in the number of people because each group participated.

That's seventy people in all. There were more than 20 people left in the habitat, and all the personnel were arranged.

One by one, the members of the divided group boarded the battleship of the mercenary group.

After arranging the defense of the station, the mermaid commander boarded the battleship that had been waiting for a long time with Chen Tianci and slowly drove towards the entrance of the rift.

The mercenary warship came to a halt kilometer from the entrance to the rift.

A large number of signs of life have been shown on the life detector.

These are deep-sea king crabs that thrive and grow nearby.

The crowd first caught a large number of deep-sea king crabs nearby. After the catch filled a shipload of supply ships, the shipload of king crabs was transported to the king crab trading city, in exchange for a large amount of money, which was distributed to the mercenaries waiting for the commission.

Then, Chen Tianci followed the first group of people to board a deep-sea flying boat, separated from the battleship, and slowly drove towards the depths of the rift.

As they went deeper, the situation in the rift valley became clearer.

On the charts, this is an area that has been explored. This area is not very dangerous, except for some deep-sea undercurrents to be aware of.

After passing through the dense deep-sea undercurrent, the deep-sea flying boat in which Chen Tianci and others were riding stopped on the seabed ground inside the rift valley.

Chen Tianci and the first group of people wore diving suits and slowly walked out of the flying boat.

Because they were on a reconnaissance mission, it was necessary to quietly advance the exploration into vague and unknown areas in this way.

So, they all left the flying boat and stepped onto the bottom of the sea.

"Don't get too far away from me." Chen Tianci said to the team members around him through the communicator.

Everyone responded, keeping a distance of about one meter to three meters from Chen Tianci.

With Chen Tianci as the center, the crowd spread out in an oval shape.

As they went deeper, the situation around them was gradually probed clearly.

The task of the first group was quickly completed.

The second group followed.

Chen Tianci never left. After the next group of people picked up, they began to explore further.

This rotation went all the way to the seventh group.

Just when he was in the seventh group, Chen Tianci's heart suddenly tightened.

A not-so-good feeling suddenly popped up in the depths of his heart.
