This runic formation on the door of the hall is broken, and when I checked it against the three I had gotten from the Pyramid, they were all different; the similarity it had was that all of them are broken.

The formation on the door changes; nobody knows at what time interval it changes. Still, every time a new person comes, they will find a different type of broken formation on the door.

As I had said earlier, this broken formation is very dangerous. I have to break it without making the slightest mistake; otherwise, lots of dangerous formations would be activated, and I would be dead before I knew it.

The thing is, it is a lot harder to break a broken formation than the complete one; I will have to design a comprehensive formation that would take everything this broken formation throws at it and break it without leaving anything.

The task is hard, and I have to do it in a limited time, but I have confidence I can do it. This hall, very well the things I need, and for that, I will do it. 

After I made my mind, I started to study the formation comprehensively before taking out the calibrator forty-five minutes later and begin to solve the formation. The Astral Garden Tower had really upped my formation solving ability, and when I came back to read those books and absorbed their knowledge, I had even better.

I had been working especially hard to studying runes, not only to create better inheritance but also to try my hands at that library. 

While I do not think current abilities would help me solve that puzzle, I am improving steadily, and one day, I will improve enough that I would confidently walk into that library and solve that puzzle and get my hands on that library and all the juicy knowledge it has.

Time passed by, and with Ashlyn as a guard, I continued to work on the formation without any worry, and nine hours later, I finished with the runic formation.

I have complete confidence that I would be able to break this formation the door with the formation I had designed. I have to have full confidence; If I did not have that, I would have kept working on it more as the slightest mistake could doom me.

With formation prepared, I removed the air pen. I am not using the calibrator to project the runes; it uses too much power, especially to break such powerful doors, and I do not want to waste powerful energy crystals; instead, I am using the air pen which I had filled with a large amount of different types of runic inks, which would help me break the different types of the formations.

While creating the runic ink is a hassle, but it is very useful, low-level herbs and minerals could create quite powerful runic ink 

I selected the ink in Air Pen and projected the formation inside it; just as I did, hundreds of runes began to come out of the air pen, and within a second, a floating runic formation appeared in front. In the academy, I used the month of time to bond with it.

Now, I just have to project the runic formation I want to draw, and it will draw it within a few seconds. It is a little more time-wasting than using the calibrator, but it saves a lot of money.

As the formation appeared in the air, I pushed it toward the door and moved as far as I could. This is also one of the reasons why I used an air pen instead of the calibrator. With calibrator, I have to maintain a specific distance; with the air pen, I could create as much distance between me and the target.

Buzz!

The moment I had stopped at a distance, the exact moment the floating formation stuck on the door and buzzed before the runes started to shine, and they began to move around to cover the broken runic formation on the door.

Crack Crack Crack

Within few seconds, my formalization covered the broken formation, and as they finished with it, they shone brighter, and cracks began to form on runes of both formations, and they have started to turn to dust and float away.

About a minute later, both formations had disappeared from the door, leaving it ripe to open; According to the information I had received from the Pyramid, the door will stay just as it is for thirty to forty seconds before a new broken formation covered it.

I looked around for any possible danger that might activate with the formation breaking, and when I did not see anything, I appeared beside the door and pushed it gently.

Kerrr!

The door opened with a slight noise and gave me a glimpse of the vast hall in front of me. The information is right; the hall had been expanded with the spatial principle, which is now collapsing state, the tense of rifts visible to me, some are big, some are small, some are moving, some are stable on their spot.

Getting caught in the spatial rifts would be extremly dangerous; these thin rifts would cut me into the pieces while the big ones would suck me inside them, and once I do, I will be finished.

These ruins are in the area of influence of our world but are not on the world; the spatial sea there extremly dangerous, so dangerous that anything that is not Master class Tyrant would be shredded in the fractions of seconds, even masters would not be last there for more than few seconds.

These rifts are the most obvious danger of this hall; there are others too, like this hall which is quite unstable and could collapse and turn into the black hole any second that will swallow everything that is present in this hall.

There are also hidden formations that could be activated at any moment. I have to be careful of every step and every breath I take in this hall lest I activate them accidentally and end up losing my life.
