2019 A Vault Inside A Vault

The symbol of the Calamity Ruin Beast was not something that exactly reflected a good image.

For someone to use it like this in a vault was a display of arrogance. It basically meant that they were fine associating their image with an ominous beast like the Calamity Ruin Beast.

This made Lin Mu think that whatever power this vault belonged to, it wasn't exactly a good one.

'If it weren't for the fact I'm in a dream, I would be quite worried about being in here.' Lin Mu thought to himself.

Having at least figured out what beast the symbol was derived from, Lin Mu decided to explore the vault further.

"Maybe there are other clues to what place this is or whom it belongs to," Lin Mu reckoned.

He looked through the various items that were kept in the vault and tried to find more information, but didn't discover anything substantial. This was until he opened a large metal cupboard. The cupboard didn't have the same symbol of a polyhedral stone and the Calamity Ruin Horns though, instead it had a character carved in.

"Dao Script… Opulence." Lin Mu recognized the character.

It showed that there was a great value to the cupboard. This made Lin Mu interested, as he reckoned there was probably something important stored in it. Something that might be able to shed more light on this place's identity.

"Huh… this is a doorway?" But when it was opened, Lin Mu was surprised.

He thought something would be kept inside, but it was actually the entrance to what looked like an empty corridor.

"No, wait… it isn't an actual physical corridor." Lin Mu narrowed his eyes, finding some peculiarities.

Lin Mu looked at the inner edges of the cupboard and saw the fine runes that were written on it. He couldn't use his Immortal sense, and as such, couldn't tell if this cupboard was an immortal tool or not. But seeing these runes, he was sure that there was definitely a formation array imprinted onto the cupboard.

"I can't use Spatial Perception either… Hard to confirm it." Lin Mu muttered to himself.

He stroked his chin and thought of another approach. He closed the metal cupboard and looked at its back, where it was put up against the wall.

At first, it looked like the wall and the cupboard were attached.

"Damn, this is heavy." Lin Mu used some force, but the Cupboard was firm.

After a few more attempts though, Lin Mu managed to make it budge, causing a thin gap to appear at its back.

"Alright, looks like it really isn't attached to the wall." Lin Mu confirmed that the wall was indeed solid. "This means… this cupboard is actually a Spatial Storage tool." He understood.

Now he understood why there was the character of Opulence carved on the front of the metal cupboard. It was a secure Spatial Storage tool that also functioned as a secondary vault.

'Since I'm in a dream, it opened without any issues. But I'm sure in reality it would be highly secure and would need some kind of key to open.' Lin Mu thought to himself before opening it again.

There were no energy fluctuations, and neither was there any spatial disturbance. Or even if there were, Lin Mu simply couldn't sense them in his current state. As such, the only way to investigate it was to go in directly.

Which was exactly what he did.

"No harm, no foul in a dream." Lin Mu said and took a step inside.

~shua~

As soon as he did though, he saw the surroundings blur. He wasn't startled by it though, and continued through the corridor. There were no light sources in the corridor, and yet it was lit up perfectly.

Its walls also seemed to be made out of the same kind of metal that the cupboard was made out of, and there was no sign that this was actually an illusory space.

~Deng~DENG~

Lin Mu knocked on its walls and felt the metal like sound from it.

"It really is solid… Hmm, perhaps this isn't an illusion created by the array, but an actually corridor kept inside the cupboard. If it's a higher grade Spatial Storage tool that allows an entire person to enter it, then it makes sense to simply put in premade solid structures inside it, rather than complicate it with arrays." Lin Mu analyzed. 'Not only would it reduce the complexity of the array, it would also bring down the cost.' He understood the reasoning behind it as well.

With that said, he continued to walk through the corridor that didn't seem to have an end at first. It was completely straight and flat, and yet Lin Mu didn't see anything at the end.

'Almost as if I'm staring into two mirrors facing each other.' Lin Mu almost felt like it was an infinite mirror corridor.

Wanting to cover this soon, Lin Mu simply decided to run.

~huu~

Taking a deep breath, Lin Mu burst into a sprint. Since he didn't have his cultivation base, he was definitely not as fast as he usually would be, but he was still several times faster than a mortal. He was already running at the speed of a sprinting horse.

Something still carried over to the dreams and it was the peak quality of his body despite having no cultivation base as of now.

Thankfully, after sprinting for about five minutes or so, Lin Mu finally reached the end of the corridor where another door stood.

This door had no symbol on it though and looked rather plain with just a single doorknob.

"Let's take a look…" Lin Mu muttered and pushed it open.

The door opened without making a sound and revealed the room inside it.

"This is even bigger than the previous room…" Lin Mu estimated that it was at least three to four times the size of the previous hall.

But there was a glaring difference here.

"It isn't filled with treasures."
