"So, Man Zun is equivalent to the Xuanxu realm?" Song Xianglan said thoughtfully.

"Yes, there is a Barbarian King above the Barbarian Lord. The inn clerk doesn't know much about this level. According to my estimation, the strength should be above the late stage of the Xuanxu Realm, and may reach the peak of the Xuanxu Realm."

"But judging from what the guy said, it seems like there shouldn't be that level of existence here."

Jiang Tian said lightly.

"I understand, that is to say, the strongest opponent we encounter here may be the Barbarian level!"

Song Xianglan frowned slightly, a trace of worry flashed in her eyes.

The division of martial arts realms here is rough and chaotic. The weak warriors at the Barbarian level may only be equivalent to the ordinary Xuanxu realm, while the strong ones may reach the middle or even late stage of the Xuanxu realm.

If he encounters the former, Jiang Tian may be able to cope with it, but if he encounters the latter, the situation will be completely different.

"Are there any powerful people here? I hope you won't encounter someone too powerful!"

Song Xianglan sighed softly and her expression became solemn.

"Judging from the situation in Sand Crystal City, this chance should be small, but everything is possible. But as long as we don't encounter several late-stage Barbarian masters joining forces to besiege us, we should have no problem in protecting ourselves."

Jiang Tian shook his head and smiled, seemingly not too worried.

The reason why he sent the spirit-devouring rats here to investigate was mainly to verify a certain analysis and guess.

Now it seems that this guess has almost been half fulfilled. Next, it is time to completely reveal the mystery.

As they continue to move forward, the spiritual energy of the surrounding world becomes more and more intense, and it is almost catching up with some medium-sized empires in the Qingtian Sect area.

Although the two of them were not too surprised, they were inevitably surprised.

Such conditions are enough to give birth to a large number of powerful people in the Xuantian Realm, but if we say that "Barbarian Masters" are born who are equivalent to the Xuanxu Realm, it may be a bit reluctant.

Perhaps, there are no powerful men of the Manzun level here?

rumble!

Boom!

Soon after, bursts of roaring sounds were heard from the front, and at the same time, the entire underground space became more open.

The two of them suddenly arrived in a huge underground city!

"I didn't expect that there would be such a city hidden in the vast sea of ​​sand!"

Song Xianglan took a deep breath, and her heart was shocked!

It is only a small corner, so it is not difficult to infer that the scale of this city is probably not much smaller than that of Sand Crystal City.

Jiang Tian was also greatly surprised, but he had no time to express his feelings.

The two continued to move forward, and the roar from ahead became louder and louder, and continued continuously.

As they continued to approach the source of the roar, both of them noticed some faint spiritual power vibrating and spreading in the void.

In front, there were even shouts from warriors.

"This is..." Song Xianglan was shocked!

"Space spiritual power!" Jiang Tian's eyes narrowed sharply, "My guess is indeed correct. This is the source of the crystal material output!"

The two looked at each other, took deep breaths, and were deeply shocked.

Judging from the spiritual power existing in the void, the quantity of those materials is definitely not very small, otherwise it would never be able to support such a large underground city.

But at the same time, problems also arise.

Where do the produced grain materials go?

The people in the City Lord's Mansion obviously can't consume so much materials. This underground city is not newly built and has obviously existed for a long time.

Where were the grain materials produced in large quantities over such a long period of time placed?

What use has it been put to?

Their thoughts were surging, and they felt more and more strange.

"Walk!"

Jiang Tian waved his hand and swept forward with Song Xianglan.

Soon after, they arrived near the source of the roar.

In a huge pit ahead, there are a large number of warriors coming in and out, and huge magic weapons are also placed.

The heavy roaring sound was caused by those large magic weapons.

Here, there is a mineral vein, a mineral vein that produces crystalline materials!

Jiang Tian did not act in a hurry, but bypassed this place and continued forward.

After some exploration, he found that there was not only one such mine, but at least five or six!

However, the spiritual power fluctuations emitted from the veins are different in strength, and obviously the grades of crystal grains produced are also different.

"Go there!"

Jiang Tian selected a vein with the highest grade, and quietly passed by with Song Xianglan.

The spatial spiritual energy around this mine vein is rippling, and it is obviously stronger than the other places. There are also the most guards here, and it is obviously the most important place in this mine vein.

"This underground mine is extremely hidden, but these people are still so well-guarded, which shows the value of these crystal grains!"

Jiang Tian's eyes flashed and he murmured to himself.

"Weird!" Song Xianglan frowned slightly, feeling a little surprised.

"Brother Jiang, look, this mine is so large in scale, and the magic weapon installed at the entrance of the mine is quite impressive, but the crystal grains it produces seem to be a little less, no, it can be said to be completely disproportionate!"

"Indeed!" Jiang Tian nodded slowly, not surprised by this.

In fact, he had already observed the weirdness here.

Although the spatial spiritual power emitted from this vein is extremely clear, and the magic weapon used to mine crystal grains at the entrance of the mine is also huge, in fact, the output of crystal grains is quite small, and the speed is also very slow.

The huge mine mouth, the huge mining tools, and the slow and sparse output give people a weird feeling of killing a chicken with a bull's-eye.

"This can only explain one problem!" Jiang Tian's eyes flashed.

"What?" Song Xianglan asked.

"It shows that the difficulty of mining these materials is quite high, and their quantity is also extremely rare!"

Jiang Tian nodded heavily and said decisively.

"Indeed!"

Song Xianglan had no doubts. After the two of them observed it, it was almost obvious.

Although the crystal grains produced by the other mines are slightly more, the spatial spiritual power emitted is obviously not strong, and the aura is slightly mixed.

This also means that several mineral veins here produce crystal grains with very different grades.

"There is no doubt that the weapons of the guards at the City Lord's Mansion are mixed with those inferior crystal grains. Otherwise, judging from the output of this core mine, it would be impossible for them to use them at will."

Jiang Tian's eyes flashed, becoming more and more convinced of his judgment.

But what surprised him was that the fusion and crystal grain materials on the weapons of the elders of the City Lord's Mansion did not seem to come from this core vein!

This is a little strange!

Realizing this problem, the two of them suddenly thought deeply, and their expressions became strange.

"It seems that the situation in this underground city is much more complicated than we imagined!"

Jiang Tian nodded and smiled, a mysterious look flashed in his eyes.

"Brother Jiang, what should we do next?"

Jiang Tian frowned slightly and fell into deep thought.
Chapter completed!
