When the third day came, the entire Black Fire City was also in a state of restlessness, and now here, I don't know how many forces from the Black Flame State have gathered, and they are obviously all here for that Flame Pulse Vein.

Although this flame marrow vein is only a sixth-level vein in the evaluation of Cangxuan Sect, this is only relative to a big family like Cangxuan Sect, if it is replaced by a top force in the Black Yan Prefecture like Yanding Sect, this vein alone can eat them several times.

Under normal circumstances, once this kind of mineral vein has the intervention of the giant sect, these ordinary forces are basically not qualified to get involved, but this time the situation is different, because this flame marrow vein is not within the jurisdiction of any giant sect, so it belongs to the ownerless, and because the four giant sects check and balance each other, no one wants to let the other party take advantage, so they are cheaper than these ordinary forces, otherwise, under the four giant sects, they really don't even have to drink soup.

But even so, at present, this Flame Pulse Vein, the richest area, has been occupied by the four giant sects.

But it doesn't matter, they can settle for the next best, as long as they can occupy some of the peripheral Flame Marrow Veins, it will also be a great gain for them.

Therefore, in just three days, almost ninety percent of the forces in the Black Flame Prefecture have sent their elite men and horses to rush to the Black Fire City, waiting for the day when the battle for the flame marrow vein will begin...

…

in the room.

Zhou Yuan sat on the bed, his body did not move, and between his palms in front of him, the mottled and deep wooden beads slowly rotated, and wisps of pure Yimu qi were constantly absorbed and poured into Zhou Yuan's body.

On the surface of Zhou Yuan's body, the turquoise points of light kept flashing, and if you looked closely, you could find that these points of light existed in the depths of flesh and blood, which was quite mysterious.

The smell of life rises, full of the smell of life.

Click!

Suddenly, there was a subtle cracking sound, only to see that the wooden beads between Zhou Yuan's palms actually cracked, and then the light began to dim rapidly, and finally turned into powder one by one...

That's because the Otogi Qi contained in it is absorbed as much as possible.

When these wooden beads turned into powder, Zhou Yuan's closed eyes also slowly opened at this time.

He looked at the powder that fell down, and his eyes also flashed with regret, and as the Qi of Yimu in it was absorbed by him, this source treasure was obviously scrapped.

Fortunately, though, it's not a flat loss...

Zhou Yuan lowered his head and looked at his body, only to see that on half of his body, green points of light loomed, and at this time, these points of light echoed each other, and the light spread out, actually linking them all.

Faintly, it seems to be an extremely ancient and obscure pattern.

However, it doesn't look complete.

"Taiyi pattern, half perfected..."

Zhou Yuan was both a pity and a surprise, it was a pity that even if he absorbed the bracelet made of the thousand-year-old wood, he still did not completely perfect the Taiyi pattern, but the surprise was that even if it was only half perfected, this "Taiyi green wood mark" seemed to begin to show its subtlety.

At this time, Zhou Yuan could clearly feel the breath of life surging in his body, and under the infection of that breath, every part of his body was bursting with tremendous vitality.

Even the source qi in the body has become longer.

Zhou Yuan's left hand, which was covered by half of the Taiyi pattern, slowly clenched, his eyes flashed slightly, and he took out a sharp dagger, and the cold light slowly swam from the blade.

The cold light swept by, bringing blood stains.

I saw that a hideous blood mark appeared directly on Zhou Yuan's arm, and the bones were deep visible, and blood flowed out.

However, as soon as the blood marks appeared, there were green points of light flashing in Zhou Yuan's flesh and blood, and the rich breath of life was transmitted, and then Zhou Yuan saw that the blood was stopped in an instant.

And the deep scar is also slowly squirming, and the granulation is growing, but in a few minutes, all the scars will be repaired...

Zhou Yuan looked at this scene, and the joy in his eyes could no longer be hidden.

Even if this "Taiyi Green Wood Mark" has not even been completely perfected now, its ability has begun to be revealed, at least for now, Zhou Yuan's physical body recovery ability is probably no worse than those external refiners who specialize in cultivating the physical body with source qi.

And when the Taiyi pattern is completely perfected, this recovery ability will surely be able to skyrocket again.

The scariest thing is that this is just the beginning... Because only when the Taiyi pattern is formed, Zhou Yuan can completely turn the absorbed Yimu qi into "Taiyi green wood marks".

In the future, when this technique is truly completed, I am afraid that Zhou Yuan will really have one... Immortal.

At that time, as long as he didn't encounter the kind of devastating attack like being bruised and scattered, no matter how serious the injury, Zhou Yuan would be able to recover gradually...

This will undoubtedly give him a huge advantage when it comes to life and death battles.

Zhou Yuan nodded with satisfaction, these three days of retreat can be regarded as a gain.

"Da-da."

At this time, there was a knock at the door, and Zhou Yuan hurriedly got out of bed and opened the door.

At the door, Li Qingchan stood pretty, her beautiful face was as cold as ever, she glanced at Zhou Yuan who opened the door, and said lightly: "If you don't come out again, we plan to leave." ”

Although her tone was light, it was not difficult to hear the slight dissatisfaction in it.

After all, since coming to Black Fire City, Zhou Yuan has been hiding in the room directly except for playing a gambling stone, and this attitude is really negative.

This time, Zhou Yuan's quota was guaranteed by her, but now even Elder Wu has a lot of complaints about it, if it weren't for her holy son's face, I'm afraid even she would be reprimanded.

When Zhou Yuan heard this, he was also a little embarrassed, so he could only apologize quickly.

He also knew that although he said that he was in retreat, I am afraid that in the eyes of others, this is nothing more than an excuse, after all, how much improvement can be made in three days? It's just a temporary cram.

And he never exposed the "Taiyi Qingmu Marks", so he just apologized and didn't explain too much.

When Li Qingchan heard Zhou Yuan's apology, she only sighed imperceptibly and shook her head: "Let's go, the battle for the Flame Marrow Vein is about to begin, and we are about to leave." ”

"In addition, although you are only assigned outside the inner circle this time, don't complain, and take up the area assigned to you as a credit." Li Qingchan admonished.

The so-called core circle is naturally the richest area of the mineral veins in the Flame Marrow Vein, where the competition is extremely fierce, and it is also the place where the four giant sects fight.

But Zhou Yuan was not arranged to go in, but was only arranged outside the inner circle by Elder Wu, and the area here was the place where those forces in Heiyan Prefecture competed, and the intensity was naturally not as strong as that in the inner circle.

Of course, when it comes to the final merit, it is naturally inferior to others.

When Zhou Yuan heard this, he also nodded slightly, his expression quite calm.

Seeing this, Li Qingchan didn't say anything more and turned away.

Zhou Yuan followed closely.

On the top floor of that floor, when Zhou Yuan and Li Qingchan came here, they saw that Elder Wu, Zhao Zhu, Bai Li and others were already waiting here.

"Hehe, Senior Brother Zhou Yuan's three-day retreat must be a great gain, right?" That Qin Hai looked at Zhou Yuan with a smile and said jokingly.

Zhou Yuan glanced at him and ignored it.

Elder Wu's gaze also stayed on Zhou Yuan for a while, and he couldn't help but sigh, thinking that he also felt a little headache for Zhou Yuan's existence.

Because putting Zhou Yuan outside the inner circle also means that they have to give up an area within the inner circle.

But there is no way, Zhou Yuan's strength is not qualified to compete with others at all.

Elder Wu's robe shook, and ten points of light flew out and fell towards Zhou Yuan and the others.

Zhou Yuan and the others all took it, only to see that it was a small jade the size of a thumb, the jade shimmered with luster, and there were source lines looming on it.

"This is a sound transmission stone, it can be transmitted for a short time within a thousand miles, you can wear one each, and after entering the flame marrow vein, you can use this to make a little contact to know your own situation." Elder Wu said.

Li Qingchan and Zhao Candle all nodded, and then stuffed the jade into their ears.

Seeing this, Elder Wu waved his robe, only to see the source qi emanating from under his feet, like a cloud, including Li Qingchan, Zhao Zhu, Zhou Yuan and others.

"Let's go."

When the sound fell, the source qi cloud was already carrying everyone into the sky.

At the same time, in the huge Black Flame City, I saw countless Dao Source Qi lights and shadows rising into the sky, like locusts, roaring towards the Black Flame Mountain Range in the distance.

This battle for the marrow vein, which affected the entire Black Flame State, finally kicked off.
