When she heard the story of Heaven, the first thought that came to her mind was that nothing should be judged.

It is not a matter so light that it can be evaluated based on individual beliefs.

The only thing that moved her was the sense of mission to see with her own eyes the whole story of a huge flow that must have started 20 years ago, or even longer.

Sein entered the master mode of Istas.

As green letters flashed on the panel, I quickly entered information by combining several symbols.

Shiina, who had been waiting patiently, asked without suppressing her curiosity.

�By the way, did the Upper Eastas really exist?�I know that even the intelligence agents of the NIS returned without finding anything.�

�The upper level exists.�There�s just no way to get in.�It was designed that way from the beginning.�Even I, who analyzed all the patterns of Istas, made it inaccessible.�

Sirone looked around at the warehouses scattered everywhere.

I wondered if an inaccessible room could exist when all the warehouses had already been individually dismantled.

�How is that possible?�In fact, you can enter any warehouse now.�That�s why Sain also made the master key for Estas.�

Sain came here and observed Sirone closely for the first time.

I knew that I belonged to the project from the moment Gaold introduced me with special care, but no matter how I look at it, I was just a soft kid.

�How do you know the master key?�

�I am a member of the Supernatural Psychic Research Society.�Among my friends, there is a Servant, and that friend was like that.�The Master Equation of Istas could not be made more beautiful no matter who touches it.�

Sein didn�t laugh.�But the explanation was more detailed.

�Perhaps.�It is an equation that equates a complex 4-dimensional diagram to a 3-dimensional one.�

The mathematical elimination of one dimension can be compared to the difficulty of making ants understand human language.�That�s why anyone can find a research society with a master equation.

A map that has a three-dimensional shape but actually finds four-dimensional coordinates.

�Upper floors are not limited to space.�

Sein nodded.

Sirone�s insight was quite good, but if he couldn�t achieve this level, he was not qualified to participate in Gaold�s project in the first place.

�okay.�In three dimensions, Istas is just a warehouse made up of 89 buildings.�But the upper level is on a higher level than that.�That�s why the agents couldn�t find it.�

�In addition to a specific space, do you mean that a specific time has to coincide?�

�That�s right.�Taking the 333 cube as an example, when the cube at coordinates 1. 1. 1 is moved to coordinates 3. 1. 3, what changes is time in addition to space.�No matter how fast you turn it, it takes 0.1 seconds.�This is called space-time.�I came up with this idea and found a way that no one could approach the maze.�It is to hide the space-time of the maze at the origin of the cube.�

Suddenly, everyone was listening to Sein.

Even Alpheas, who had once been Sein�s teacher, was now in a position to learn after 20 years.

�No matter how the cube is rotated, in other words, no matter how the pattern of Istas is changed, the cube�s space-time origin never moves, so the upper layers can also be completely concealed.�What you created to calculate this is the Master Equation of Eastas, which you are currently using.�

Saliva ran down Sirone�s throat.

I didn�t expect that there was such a serious reason for the Master Equation, which I thought was nothing more than a prank of a study group in the dark. JrNovels.com
