In order to save himself, the prince summoned 100,000 dragon riders at the start.

"Moreover, even if this spirit stone vein is fully mined, it will only yield a few trillion spirit stones!"

"It's far more worthwhile to let it function as a mineral vein, capable of nurturing an entire small world!"

Upon hearing this, Lu Yuan's eyes flickered for a moment.

He can feel it too.

At this moment, this spirit stone vein is radiating a rich and dense spiritual energy, nourishing this world!

and.

It is still absorbing spiritual energy from the external void to strengthen itself!

Although it's slow, it is definitely growing!

After a moment's thought, Lu Yuan realized that what Zhen Jiu said actually made a lot of sense!

It's like depositing a huge sum of money in a bank.

You will not only receive interest.

In addition, you can also get extra services on a regular basis!

why not!

"Zhen Jiu, you're right!"

"Then let's do as you say, and refrain from mining for the time being!"

After thinking for a moment, Lu Yuan agreed to Zhen Jiu's suggestion.

We've decided to temporarily halt mining of this spirit stone vein!

Anyway, this spirit stone mine is bound to be there, and he still has enough spirit stones.

If it's not enough, we can mine more; there's still time!

Lu Yuan reluctantly shifted his gaze away from the spirit stone mine.

Their attention shifted elsewhere!

after all.

They've discovered a vein of spirit stones.

Who knows if there are other good things in this world?

.......

then.

Lu Yuan's divine sense began searching other places as well!

Originally, Lu Yuan had no expectations.

after all.

Spirit stone veins are extremely rare and hard to come by!

however.

When Lu Yuan's divine sense arrived at the very center of this small world, at the largest hall...

He actually discovered an unusual place!

At this time.

Lu Yuan looked at the huge black stone pillar made of an unknown material deep underground in front of him.

"No way? There really is one?!"

At this moment, Lu Yuan's face was full of astonishment!

He was just looking around.

Surprisingly, a treasure actually appeared!

Lu Yuan calmed himself and quickly brought his gaze closer.

Only then did I realize that this black stone pillar did not seem to be made of stone, but rather it was made entirely of the uncorrupted bones of some kind of ferocious beast at the Emperor Realm!

But yes.

Only the incorruptible bones of a ferocious beast at the Emperor Realm can barely withstand the erosion of endless years!

Ordinary materials would have turned to ash long ago!

"But what's the point of putting a bone here...?"

Lu Yuan was a little confused for a moment.

Indeed, the incorruptible bones of a ferocious beast at the Emperor Realm are also top-grade treasures.

Compared to a spirit stone mine, it's nothing!

There's absolutely no comparison!

Why would anyone put this thing here for no reason?

However, at this moment, Lu Yuan seemed to suddenly think of something.

My heart skipped a beat!

"By the way! Some of the cultivation techniques in this world seem to be recorded on the bones of some demonic beasts."

"Could it be..."

Lu Yuan's heart stirred, and he quickly looked closely at the piece of uncorrupted bone!

really!

He actually discovered a line of tiny, fly-like writing on it!

but.....

"Uh... what does this say?"

Lu Yuan scratched the back of his head somewhat awkwardly.

The inscription on the stone pillar appears to have been carved hastily and is somewhat illegible.

However, this script was not one that Lu Yuan recognized.

He doesn't know him at all!

However, Lu Yuan had a solution. He summoned the system and asked it directly:

"System, come out here and translate this line for me!"

[Ding! Translating a line of ancient text requires 100 points of Luck!]

"Stop talking nonsense, I'll pay! Hurry up and translate it for me!"

Lu Yuan waved his hand impatiently.

A mere hundred points of luck is nothing to Lu Yuan right now!

[Ding! Payment successful! System translating...]

[Ding! Translation successful!]

[Immortal-grade cultivation technique: The Great Void Unity Holy Scripture!]

[Content: The vast and boundless heavens, the boundless and mysterious depths, the ultimate heaven and earth, the great Dao is simple...]

【….】

"A celestial-grade cultivation technique?!"

Looking at the text translated by the system, Lu Yuan's expression was somewhat strange.
