In the underground galaxy veins, it is still the same as before, countless stars are dazzling and dazzling, and the brilliance is dense, making people intoxicated when they take a second look.

Although Duan Heng was still full of doubts, he still couldn't figure out why such a good thing happened to him, but at this moment, he didn't dare to slack off.

After all, if someone catches it, then maybe they will be thrown into the three thousand small worlds again.

However, the strange thing is that there is no one to guard this galaxy vein, and the entrance to the crypt where the miners came out is tightly sealed.

After taking a turn around, Duan Heng found that with his current strength, he was afraid that it would be difficult to sneak out, and if he forcibly collided, it would be even more stupid.

After observing left and right, his eyes locked on the top of the galaxy's ore vein, where was the huge mountain's belly, the mountains and rocks were rugged, under the starlight, like monsters, but it was a good hiding place, because he remembered very well before, those guards who drove the mine slaves seemed to be extremely afraid of approaching the galaxy, and they all kicked the mine slaves down from a distance, and then immediately retreated, so there should be no problem.

Just when Duan Heng was about to fly up, he saw that in the galaxy not far away, something seemed to be drilling out, which caused great fluctuations, countless starlight rippling, beautiful,

It's just that this kind of beauty made Duan Heng feel a huge threat, and for a while, he couldn't care about hiding anymore, and hurriedly retreated, and at this moment, countless starlights rose, and a huge black monster slowly emerged, this monster had no obvious outline, like a huge ball, and because of the galaxy veins, the upper half of the body was only a few dozen meters thick, but through the starlight. The lower half of its body is thousands of miles thick, to say the least.

As the monster gradually surfaced, Duan Heng saw the four wings on its back again, but from beginning to end, he didn't see the head of this monster.

But the only thing that is certain is that the strength of this monster is beyond imagination.

Duan Heng tried not to move as much as possible, and he didn't dare to breathe. And the monster just kept coming out of its body, which was strange to say, originally this galaxy vein didn't look big, for example, the galaxy was only the size of a small puddle dozens of meters wide, from the ground to the top of the rocky mountain, that is, dozens of meters high, the whole space was not as good as a football field.

But as this monster appeared, Duan Heng was surprised to find out. The space here is increasing, and in a short period of time, the top rocky belly has been raised from tens of meters high to several thousand meters from the ground, and there is no end.

As for the monster's body, it is also constantly expanding, and the coercion brought to Duan Heng is also getting bigger and bigger, and it is the most serious time. He could only huddle in the corner and hold his head shivering, almost collapsing.

Good thing all the while. The monster didn't pay attention to Duan Heng's little bug, it was just walking through, and it didn't know where it came from or where it was going?

The whole process lasted a full hour, and then the monster disappeared. The space here gradually returned to its original state, and countless stars fell from the sky.

At this time, Heng discovered that the exit of the galaxy vein had been forcibly twisted and opened, and now it was slowly closing, no wonder there was no one to guard and guard it.

I don't want to. Duan Heng turned around and rushed over, but when he was about to step out of this exit, he still paused, and with a wave of his hand, he controlled a cold ice chain to fly out, pulling the falling star closest to him over.

Then he didn't have time to look at it, he turned around and ran out, and then almost within a few breaths, the entire galaxy vein was back to its original state again.

The underground passage was very deep, and there was no one to guard it, which Duan Heng knew at the beginning, so he ran very fast, just running, he felt that something was wrong, because when he was sent down the galaxy vein with other miners, he remembered very well that from the entrance of the dungeon to the entrance of the galaxy vein, the difference between the entrance of the dungeon and the entrance of the galaxy vein was no more than three thousand meters at most, and in the state of normal walking, a cup of tea was enough.

But he'd been running for at least half an hour now, and he still couldn't see the exit.

Sensing that something was wrong, Duan Heng immediately stopped, closed his eyes, and silently sensed with his spiritual sense, it was very strange, this was not a maze, and there was no formation arranged, because he could sense the abundant immortal qi in the outside world, so, where was the problem?

Thinking of this, Duan Heng looked down at the star he was holding, well, it was a bit strange to say that, but he really couldn't find any other description.

This thing is still exuding a warm light at this moment, the whole is translucent cyan blue, the size of a human head, holding it in his hand, it is very warm and cool, although I am not sure what this thing is for, but this is definitely a good thing, Duan Heng can swear with his intuition.

In addition, he felt that the reason why he was lost was also because of the stars.

But after looking at it for a long time, Duan Heng didn't see anything ugly, just when he sighed and was about to think of other methods, he suddenly jumped up like a ghost and looked at the soles of his feet in horror, because, in the moment he stayed, the place where he stood was actually corroded by an inexplicable force, as if something was stealing these solid rocks.

It's terrible, the rocks in this place are specially selected, not naturally formed, otherwise in such an important place as the galaxy vein, wouldn't anyone be able to dig a hole and drill in?

Duan Heng was very sure that there was no formation here, and it was also because of this that the stone here was too hard, it was a purple electric stone specially transported from the immortal realm, this thing could be immune to most evil qi spells, and it could also perfectly shield the invasion of demonic energy, even if it was cut with the ancient sword, it could only be cut down a little.

This is the most expensive, the most powerful, and the most insoluble defense in the world of cultivating immortals, even if the immortals want to break through, there is little hope, they only need to hold an exit, and everything will be fine.

But why is this purple calcium carbide gnawed away like tofu dregs now?

Looking at the star in his arms, Duan Heng was stunned, and after a long time, an ecstatic expression appeared on his face, he probably knew what this thing was.

At the beginning, Luo Yunrong and he discussed sword cultivation and sword making, and when he said what kind of material is the best, it must be Jiuxuan Essence Gold, this thing is not only sought after by sword immortals, but also urgently needed by other immortals.

It's a pity that no matter whether it is the cultivation of the immortal realm or the immortal realm, it does not produce nine Xuan Jing Jin, this thing must be synthesized and refined, after nine hundred and eighty-one quenching, and many materials must be added before it will finally be formed, and the most miraculous place is that it is smelted into Nine Xuan Jing Jin, which requires a piece of mother iron, which is the most fundamental foundation.

But Luo Yunrong didn't know what the so-called 'mother iron' was, he only knew that once this thing appeared, it would automatically absorb the essence in the surrounding ore veins, and as for what to do next, he didn't know.

And looking at the current situation, Duan Heng has at least a sixty percent chance of believing that this thing is Luo Yunrong's so-called 'mother iron'.

After thinking about it, he put the star mother iron in his hand on the ground, but the next moment almost scared him stupid, because, as soon as it touched the ground, the star mother iron actually fell down with a whizz, as if there was a deep pit below, but in fact, this thing was frantically absorbing the essence of the purple calcium stone.

Thanks to Duan Heng, he never let go, otherwise he would really miss out on this baby.

Because at this moment, he clearly sensed the spirituality in this star mother iron, which would definitely be more powerful than a ginseng doll with limbs.

This lower paragraph is solemn, once this kind of heavy treasure appears, it will be fatal, if he does not handle it properly, the consequences will be unimaginable.

So, he had to hold the star with one hand, and then took out the broken sword buried in his left arm, but unfortunately Xiao Yueji was still asleep and could not communicate.

After thinking about it for a long time, he put the broken sword on top of the star mother iron, and as expected, almost in the blink of an eye, the sharp broken sword was devoured.

Together with the sword and sword intent that Duan Heng had stored in it, he did not let go.

And at this moment, Duan Heng sensed the awakened Xiaoyue Ji.

"Duan Heng, the situation is very wrong, where did you find such a powerful spirit? It wants to devour me, come and help me!"

Sensing the thoughts passed by Xiao Yue Ji, Duan Heng was not surprised, this star mother iron is such a divine object, even if it has just been born, the spirit contained in it must be powerful.

It's just a pity that he already has Xiaoyue Ji as a sword spirit, so he can't tolerate this spirit, and this spirit will definitely be extremely powerful in the future, he may not be able to control it, where is it more suitable than Xiaoyue Ji?

Therefore, Duan Heng did not hesitate, and through the sword intent hidden in the broken sword, he covered the tide of his spiritual sense.

That spirit certainly had an innate advantage, but after all, it was still not enough to see compared to Duan Heng's spiritual sense tide.

In just a few moments, it had been completely suppressed by Duan Heng, and then let Xiao Yueji devour and fuse it.

"Xiaoyue, have you found anything? What the hell is this?"

Duan Heng asked, he had now buried his sword intent in the broken sword, and now that Xiao Yue Ji had fused the spirit in the Star Mother Iron, then his sword intent had also controlled the entire Star Mother Iron, and he was not worried that Xiao Yue Ji would make trouble.

For a simple analogy, the Star Mother Iron is like a city that has been attacked, his sword intent is the garrison of this city, and Xiao Yueji, as a sword spirit, can only be the governor of this city without Duan Heng's permission, responsible for people's livelihood and growth.

"Hmm, Duan Heng, you're so lucky, but I don't know what it is, so-"

Xiao Yueji's voice cut off again, obviously falling into a new round of slumber.

Duan Heng shook his head, and carefully put the star mother iron back on the ground, and this time, the speed at which the star mother iron absorbed the purple calcium stone essence around it was still very fast, but it would not escape, it just surrounded Duan Heng to absorb it, at first glance, it looked like a round panda.
