5th Floor: This floor is the 'Virtual Simulation and Gravity Center'. You can activate the functions by placing your hand on the pedestal on the side. In here, you can choose virtual opponents of any level, be it a single or group combat and any type of surroundings to hone your battle and strategic skills. Since you will only be virtual projection, you will not suffer any injuries or death, but only some mental exhaustion. You can also train your body like how Saitama does with increased gravity in the room. You can increase the gravity up to a billion times. (A/N: Our MC might need a gravity suit to control his speed or not, I feel bad for all the monsters till 18th floor)
6th Floor: Let's just say this is a prison. Any enemy, be it a human or a monster, you can imprison them in this place after defeating them. Once they are on this floor, the chains on the ground will bind them both physically and spritually. In another words, they wil never ever escape this place until you let them go free. There are 99999 golems here, and each golem governs an area of 1000 square kilometer. You can use them to torture and break the prisoners so that they can submit to your will. (A/N: I bet the 'prisoners' will poof in the first round of torture. They can also be summoned from the pagoda to fight and help for you. Their strength is always proportional to your strength.
7th Floor: This floor is the NAVIGATION ROOM. Basically it works like how the map reveal from Death March works. You can find the whole detail of the map be it 2D or 3D. You can also spy on anyone and anything without getting noticed. This floor works along with the system's mapping function.
8th Floor: This is the 8th floor "ATLAS KINGDOM". The area is 1000 times bigger then our world. This is the place where some of the strongest and rarest monsters live and breed. The only rule on this floor is "survival for the fittest." You can fight, practice and tame the monster to obey your will. There are some stubborn monsters too. You can dtag them to the 6th floor after defeating them. The weakest of the monsters are easily at that of a level 10 adventurer. But the strongest monsters whose levels are those that of a level 100 adventurer and above will only fight you if they are challenged, threatened or provoked by you. There are restrictions on this floor which prevents you from using your weapons, so you're on your own.
9th Floor: This floor is the "TIME CHAMBER". Here time moves at 1:10000000000 compared to outside world. This floor is fixed with sealing and formation techniques, which supply energy of all types without limit from all over the anime worlds. The ratio remains the same all the time wherever you go. This floor also has a function to summon any characters from any anime and let them teach you what they have. Don't worry about them, they will still exsist in your soul pagoda to teach someone else.
