We stepped onto the 49th floor, and just as I did, I felt the change. The floor is different from all the other forty-eight floors I had been in.

  The first thing that is most noticeable is the antral energy here; it is dense, so dense that I could literally taste it on my tongue. There had never been such dense astral energy in any place in the tower. If any herb hall had this much dense energy, then even the most common plant there would have made the fight to the death.

  The hallway of the 49th floor is stark white with a huge redwood door that had the design of huge humanoids celebrating some festival. Whoever carved the design must be an exceptional artist; when one looked at the carving, a scene couldn't help but appear in one's mind.

  If I had a lot of time, I would have really enjoyed it, but there are other, more important things I have to focus on.

  Seeing the energy fluctuations around the door, these people seemed to have tried hard to open it, but all their efforts have failed. They were not able to make even scratch on the surface of the door, though with their efforts, they seemed to bring out a complete runic design, and that is good news.

  As I looked at the runic design, a shock couldn't spread into my eyes. I was about to open my mouth and stopped myself and decided to analyze it in further detail. For the first few minutes, I felt my earlier conjecture was right and about to stop when I started to notice small details that even an expert would discard at first glance.

  At first glance, the runic diagram seemed very easy, so easy that it might not even take me an hour to break it, but as I looked at details, the formation became complicated. The more details I noticed, the more complicated it would become.

  "My god!" I muttered while still studying th formation. The formation is something I have never come across; it is of completely different designs that I am used to, follows a path that seemed quite radical.

  "The formation does not seem much difficult compared to those protected plants, our friend Jorden will not have any problems breaking through it," Rey said. From what I had come to find, he is a most trusted deputy of Commander and one of the two peak elites we have.

  "If it had been so easy to solve the formations, our Grimm friends and I wouldn't have wasted days on this door," Commander said as she looked at the Grimm Monsters before she turned to me.

  "So, Jordan, will you be able to break this formation?" Commander asked. "Ask me that question a day later, commander," I said before taking out the calibrator. If I had been looking at the Grimm Monsters right now, I would have seen their eyes shining in a strange glint right now.

  I am extremely excited right now, so much that I am literally shaking. The difficulty of this formation is so immense that even I did not know whether I would be able to solve it or not; I even felt that this formation was harder than the third circle equation I had faced in the library.

  My calibrator scanned the formation, and the next second, I started to solve it. More like begin to analyze in greater detail before I begin to solve it, I will have to analyze it completely, having a comprehender did not make things much easy this time.

  Three hours passed by, and I had finally started to solve the formation; the formation had been much harder than I had realized, but it made things even more interesting.

  I have taken this formation as a personal challenge to myself, and I will solve it using every ounce of knowledge. This formation could say to be the most difficult formation I had ever come across, and I don't know whether I could solve it not, but I believe I have the ability to solve it, and that is enough for me.

  Time passed by, and before I knew it, a day had passed, and not a single person dared to disturb me. Though, a few hours ago, I had sensed the small disturbance and looked through my soul sense, only to see three new leaders have joined in on the top floor.

  These four leaders were the ones that were seeing the exit at the 48th floor; now we have the two leaders and Grimm Monsters three, which is a good odds.

  Even after a day, the Commander did not disturb me or asked me if I could solve formation, which is good because a day is not enough to solve difficult formations such as this one.

  Nearly two days passed when I made a big breakthrough in my understanding of this formation and was able to solve it three hours later, but I did not inform them of it. I spend another half day acting like I am still solving it as I rest my mind and body before I readied myself for the things that will come after the door open.

  "I solved the formation," I said. I got up from the spot. Hearing that, the eyes of both humans and Grimm Monsters lighted up as they got ready to enter inside.

  "Why are you wasting time human, project the runes and open the door," The leader Hyenaman said, seeing me not projecting runes after a few seconds. "The power core I have is not enough; I need something powerful for runes to break the formation," I replied.

  As I did, commander camphor moved her hands toward the Grimm Monster, "We have solved the formation, its your time to do your bit," She said.

  The Grimm Monsters did not get angry as I had expected; the three Grimm Monsters discussed the things among themselves; the leopardman even came closer to runes to feel their power it went back to two leaders.

  Finally, after a minute of discussion, Hodgman took out a tiny red pearl with slight unwilling expressions…… "Here, this Red Cascade Pearl would be more than enough to provide the energy you will need to break opened the door," The Hogman said and threw the pearl at me, which I had caught with shining eyes.
