This was a huge spatial ring. In terms of size, it was much larger than any ring Chen Feng had ever seen. But of course, compared to the space of the Celestial Dan Immortal Manor, this storage ring was nothing.

In the next moment, his consciousness stopped at the mountain of treasures inside his storage ring.

"This is …" Chen Feng opened his eyes wide, shouting out in disbelief.

Within the storage ring, waves of white light constantly flashed.

It was a pile of strange stones. Just like spirit stones, it seemed to contain pure energy. However, the color of the spirit stones were green and white, but the stones here were pure white.

Moreover, the energy contained within these stones was at least a thousand times richer than that of high-grade spirit stones.

"It's actually a top grade spirit stone!" Chen Feng was extremely shocked. The spirit stones in front of him were all top grade spirit stones.

Top quality spirit stones were the rarest spirit stones in the cultivation world. In the cultivation world, a single top quality spirit stone was enough to buy a spiritual tool.

Even so, no one was willing to use top quality spirit stones to exchange for spirit artifacts. The only reason was that top quality spirit stones were simply too rare.

The value of top grade spirit stones lay in the content of the spirit energy and the purity of the spirit weapon. Cultivators above the tribulation level must use top grade spirit stones as a source of spiritual energy when breaking through. Only top grade spirit stones could support the consumption of tribulation cultivators.

Because of this, the highest currency in the cultivation world was only high-grade spirit stones. This was because whenever top grade spirit stones appeared, the experts of the Divine Tribulation Realm and above would have long since set their eyes on them.

To them, an extra top grade spirit stone was the guarantee to their advancement. As a result, the rare top grade spirit stones became a hot topic for every elder in the tribulation period.

Just like Chen Feng in his previous life, although he was the Pill Ancestor, his status was extraordinary. He had long since lost his interest in ordinary items, but he had always thought that the more top quality spirit stones, the better. Even so, in his previous life, when his ancestor failed to transcend the tribulation, he only had a few thousand top quality spirit stones.

"I didn't expect everyone to have so many top grade spirit stones in this ring." This small pile is probably no less than two thousand. " The more Chen Feng looked, the more shocked he was. This was because the place where the top grade spirit stones were stored was actually just a corner of the storage ring.

This meant that the top quality spirit stone in his storage ring was nothing!

Suppressing the agitation in his heart, Chen Feng turned his gaze elsewhere.

Just as expected, he found another pile of purple stones beside the top quality spirit stones.

"Hmm... Could this stone also be a spirit stone? " Looking at the pile of purple rocks, Chen Feng's heart skipped a beat.

This was because Chen Feng could feel a power that was even more profound than top grade spirit stones from this pile of stones. This power seemed to be above the spiritual energy, making it seem distant and profound.

"Purple? a power that is above top grade spirit stones? " Chen Feng frowned as he recalled this memory unceasingly.

Suddenly, a thought struck him and an introduction appeared in his mind.

"It is entirely purple in color and contains immortal spiritual energy. It is called an immortal stone."

This short sentence seemed to prove the type of stone in front of him.

"Immortal Stone?" This is an immortal stone that only exists in the Immortal World? " Chen Feng's heart was pounding fiercely. If it were not for his determination, he probably would have flown into a Qigong deviation at this moment.

Immortal stones, ah, in the millions of years since the cultivation world was born, there have been a few instances of them descending. When had it not been for a bloody storm, a river of blood?

A single immortal stone had such a huge influence, how could it be compared to the small pile in front of him?

If others were to find out that he had obtained such a small pile of immortal stones, then the cultivation world would truly have no place for him.

After a long sigh, Chen Feng finally broke free from the shock.

After which, his gaze shifted to another place.

The rest of the area seemed to be more spacious and empty. Some clothes and other miscellaneous items were taken out, and only two boxes were left.

"A box?" Chen Feng controlled his mind and took out the two chests from his storage ring.

One was the size of a coffin, while the other was the size of a washbasin.

"What's in it?" Chen Feng looked at the box and had an idea.

Subconsciously, he felt that the contents of the box were not simple. After all, would something that could be collected by someone who possessed immortal stones be ordinary?

"Open it and take a look!" Chen Feng extended both his hands towards the small box and gently lifted the lid.

"Huh?" Chen Feng was surprised.

Inside the small box was a yellowed book.

Taking out the book, Chen Feng was immediately attracted by the three large golden words on the cover.

"Mechanical methods?" He was now certain of the owner of the tomb.

From the moment he entered the cave, Chen Feng had been guessing the identity of the owner of the tomb. The fact that the other party was able to set up such an ingenious secret mechanism on the outer wall meant that he was most likely a machine master.

At this moment, Chen Feng was even more certain after seeing this book.

Flipping the book open, one could see many complex diagrams, all of which contained the principles and components of various mechanisms, and were extremely exquisite.

However, Chen Feng only glanced at these. There was no other reason, he could not understand them...

Opening the letter, a row of elegant handwriting appeared before Chen Feng's eyes:

I am the external disciple of the Immortal World's Divine Ji Sect, Guo Song. However, because of an exploration of ruins, I was sent into this world by a crack, leaving behind a 'Mechanical Compass', a mechanical puppet. If a fated person has the chance to ascend to the Immortal World, please inform my love Yin Chunshui. Guo Song paid his respects!

Although it was only a few short sentences, Chen Feng could read the reluctance to part from it.

"Don't worry. If I ever get the chance to ascend in this life, I will make a trip to the God Base Sect." Chen Feng closed the letter and silently guaranteed.

After putting the letter and the "Mechanical Faction" back, Chen Feng looked at the big box.

According to the letter, Guo Song had not only left behind the "Mechanism Index", but he had also left behind a golem. If his guess was correct, the golem must be in this big box.

"Open it and take a look!" Without saying anything further, Chen Feng opened the lid of the big box.

As the lid was flipped up, a strong sense of danger could be felt.

Inside the box was indeed a mechanical beast.

The mechanical beast had a sinister appearance, like a cheetah. Its entire body was forged from a type of black metal, and just a glance at it would cause anyone who looked at it to feel a chill.

"What a tyrannical mechanical beast!" Chen Feng praised sincerely.
