"Did you just feel a tremor?"

Inside the cave, Yin Zeriel's body paused slightly.

Just now, he felt a slight tremor, but it was only for a moment, and not even the earth and rocks in the cave were shaken.

If he hadn't suddenly felt panicked in his heart, he would have thought that it was a delusion just now.

"Shock? Have it? ”

Zuo Yin blinked, his face full of doubt.

She really didn't feel any vibration just now, and after rejecting the increase in the power of the star spirit, she was just an ordinary little girl.

"Maybe it's my delusion..."

Yin Zereel shook his head, suppressed the uneasiness in his heart, and continued to probe forward with Zuo Yin.

However, Zuo Yin noticed that when Yin Zeriel turned around and continued to move forward, the gem inside the magic electric rod in his hand suddenly flashed.

Zuo Yin just looked at it curiously, and didn't pay much attention to it.

After all, she didn't understand the principle of the magic electric rod, and maybe it was just normal.

As the two of them gradually went deeper, the temperature in the cave was much colder than before, and there was even a slight cold wind blowing from the depths.

And Yin Zereel and Zuo Yin also encountered the first fork in the road at this moment.

"Go this way!"

Yin Zeriel closed his eyes and sensed the cold wind blowing, and decisively chose the one on the right.

There is almost no wind on the left, and it is mostly a dead end.

There may be treasure in the dead end, but Yin Zereel is clearly more interested in this cave that is not naturally formed.

True, based on his observations, it is almost certain that the cave was not naturally formed.

The caves formed by nature through the earth's crust are not as regular as this cave.

A closer look at both sides of the rock wall reveals signs of biological excavation.

Not the marks of a man-made tool, but more like the marks of some kind of creature using sharp claws or sharp pliers.

And judging by the marks left on the rocks, these creatures are not small.

At the same time, on the surface of the cave, Yin Zereel also found traces of the actions of many small creatures.

These traces are large and small, but they can be concluded to be the same kind.

"What could it be... Hopefully that's what His Majesty Ryan is looking for..."

Yin Zereel muttered under his breath, reaching into the pocket of his clothes' lining, until he touched an angular object and held it tightly, and his heart calmed down a little.

He Yin Zeriel is also a backer, no matter what kind of bull ghosts, snakes and gods are in front of him, he will be vulnerable in front of the empire.

"Huh?"

While walking, Zuo Yin sighed softly:

"This light... It's beautiful! ”

Hearing Zuo Yin's words, Yin Zereel would also see the scene she said.

About a few dozen meters in front of them, the magic rod could barely reach the limit.

Illuminated by a deep blue light, a dazzling deep blue light is reflected there.

The stars are dotted, like a deep blue sea of stars.

When he got closer, Yin Zerell observed carefully to see clearly.

The things reflected by the deep blue light were strangely shaped crystals.

These crystals were scattered throughout the cavern in front of them, not only at the bottom of the cavern, but also scattered on the sides and top.

Illuminated by the light emitted by the magic rods, they emitted a strange and beautiful glow, illuminating the entire interior of the cavern beautifully.

"It's beautiful..."

Even Yin Zereel couldn't help but marvel at the moment.

But at the same time, he also glanced at Zuo Yin unexpectedly.

Yin Zeriel hadn't forgotten that Zuo Yin had discovered this place before him.

This can only show that in the dark cave, Zuo Yin's eyesight is even better than him.

But thinking of what Ryan said to him remotely, Yin Zereel was also relieved.

Don't provoke, don't hide, don't ask more, don't guide...

To put it bluntly, everything is laissez-faire.

Even Ryan said so, and Yin Zereel could think that Zuo Yin was not simple.

However, no matter what the identity of the other party is, he has the protection of the empire, and he does not have a sense of fear in his heart.

He's the kind of celebrity around Ryan, the kind that gets praised and rewarded from time to time.

If you want to hurt him, you can't get past Ryan first.

Thinking of this in his heart, Yin Zeriel's confidence was even more sufficient.

Even, even the original dangerous exploration of the place in front of him was saved, and he beckoned directly:

"We continue to move forward, and now there are so many high-quality crystals, I have a hunch that I will gain a lot this time."

After a period of mending, even if he just glanced at it, he could see that these crystals were not ordinary crystals.

These crystals are called Sky Crystals, and they are excellent magic storage containers.

A few years ago, these things weren't worth much, because no mage would use them to store mana.

The mana stored in the Sky Demon Crystal can only be taken out in a special way, and it is extremely cumbersome for ordinary mages to take it out, and it is not valued by everyone at all.

However, after the Trivary Council took control of the empire, the use of magic in the empire directly rose countless notches directly because of Ryan and Sindra.

This kind of empty magic crystal, from the previous unwanted, has almost become a product in short supply.

The Meredith Chamber of Commerce has been on the list of acquisitions for a long time, and a standard-sized Sky Magic Crystal is worth 1,000 gold coins.

The magic cubes that are now used in magic technology were inspired by this crystal.

Just now, the empty magic crystal in this place was enough to make Yin Zeriel and the others rich in an instant.

However, Yin Zeriel is not interested in any of this.

One is that he is not short of money at all after following the empire, and he has no interest in ground mining.

Two... Even if he digs up all the crystals now, he will hand them over to the empire in exchange for money after he goes out.

But if he waits for him to report to the empire after this trip, the empire will not lose his money, and there is not much difference between the price and his own digging.

This was a promise Ryan had given him before, in order to save him precious time on the expedition.

That's right! Every minute and second of his Yin Zeriel is worth countless gold coins!

While thinking about it, Yin Zereel still operated on his arm guard a few times, and a brief piece of information was transmitted by the arm guard.

After Ryan's personal transformation, his arm guards also have a lot more functions.

Positioning and the transmission of information to the empire are basic functions, and naturally there will be no less.

As for how the Empire received information, he knew very little about it.

It's just that I heard that the empire has a big database, and after receiving information or intelligence, it will automatically send tasks to relevant personnel.

At the same time, almost two seconds after Yin Zeriel sent the message, the Immortal Fortress had already received the message from him.

"Looks like he's found it."

Inside the Floating Castle, Ryan had an extra smile on his face.

"The appearance of a large number of empty magic crystals indicates that the surrounding magic elements are very dense, and based on the amount he has seen and has not seen, it is estimated that there is at least one demigod-level magic creature in the vicinity." Sindra spoke.

"There should be more than one, let him go and explore first. The two of them might be able to bring some surprises. Ryan laughed.

As he spoke, he also used the large database to transmit a message to Catalina and the Imperial Southern Front Legion stationed nearby.

It's just that there may be a few demigods, and it's not worth it for him or Councilor Tripali to do it personally.

The empire is no longer the empire that was about to rise.
