Realistic Tower of God: The Martial Way

Basic Information of Tower of God (Don't Read If You Already Know)

Shinsu

Shinsoo, literally "divine water" is a substance native to lifeforms within the Tower. It is produced by the Tower and flows through the surroundings like air. Shinsu exists everywhere inside the Tower.[2] Shinsu does not flow from the Outside, but is rather "created" and "produced" by the Tower itself. Shinsu can even exist in a vacuum. As of now, what Shinsu consists of or comes from is unknown.

Shinsu is essential to all living beings in the Tower, enabling their survival in multiple ways. For all of living memory, and likely prior to it, Shinsu has been an integral part of the Tower. Strong or weak, ranker, regular, or otherwise, if you run out of Shinsu you will die. It fulfills the role of life energy for organisms within the tower, as well as acting in lieu of oxygen for for breathing.

Shinsu can be utilized in a multitude of ways, given adequate knowledge, skill, resistance, and natural talent. Through Shinsu, one can attain eternal youth, extended lifespans, halt the aging process, control natural elements and, even attain the powers of a god.

Shinsu is normally not visible to the naked eye like air, unless it is highly concentrated, manifested in large amounts or is manipulated using a Shinsu Technique or item. There are exceptional areas within the tower where Shinsu is highly concentrated naturally (eg. the White Steel Eel's cage on the Headon's Floor or the sea of blood on the 43rd Floor). These locations will appear as being submerged in liquid Shinsu, and can be hazardous to enter for those who lack high shinsu resistance and adequate combat skill to defend against the Shinheuh that often inhabit there.

The first person to systematically study Shinsu was Po Bidau Gustang, the head of Po Bidau Family, one of the 10 Great Families. All terminology (jargon), standards, and units used to describe Shinsu today originated from Gustang's work.

Air and Shinsu

When Ashul Edwaru learned about the existence of something called "air" on the Outside world from the Irregulars (the term he created for Zahard and his 12 companions), he began to interview the Irregulars and performed theoretical study in order to compare the difference between the air and shinsu. Edwaru then wrote his theories in his book called Of the Tower's Weapons.

In short, Air and Shinsu has few things in common. They are both flows throughout their surroundings and essential for all living beings in each of their respective worlds, as it allows for breathing and provides moisture for the inhabitants. Lero-Ro stated that within the Tower, Shinsu replaces air and carries out all the processes that air would.

The most significant difference between air and shinsu is the laws by which it operates. Unlike air, which uniformly conforms to the laws of pressure when flowing, Shinsu has no unifying laws. It flows and behaves entirely differently in different places, sometimes it become gas and other times it become liquid, depending on other various factors, like the Floors environment, shinsu density or concentrations, and the Administrator of the floor. The flow of Shinsu determines its qualities, allowing it to appear as water, fire, light, and other phenomena and materials. Shinsu has no singular property or feature and is rather the very basis of all energy and things within the Tower.

Shinsu Manipulation

Literally, "divine water manipulation" is an advanced form of Shinsu Control to externally manipulate Shinsu to change the environment, to attack an opponent or to carry out other actions, such as flying or levitation. People who can easily control and manipulate Shinsu are assigned to a Position called "Wave Controllers". However, most Rankers, regardless of their position, are able to manipulate Shinsu to extreme degree because they have trained and mastered it for at least hundreds of years.
