Vix finally got to the two hundredth floor, now that he is fully capable of using the four major principles of energy known as Nen and its advanced techniques. After acquiring a working command of the basics, a student is introduced to a series of advanced techniques that often combine and/or derive from the four Major Principles. These techniques expand the user's options in combat manifold, but they also consume more Spirit energy than the Four Major Principles. Gyo (Gyo; "Focus") is an advanced application of Ren by which a Nen user concentrates a larger than normal portion of their aura into one specific body part. It increases the strength of that one body part but leaves the rest of the body more vulnerable. Gyo is most often used in the eyes, allowing a Nen user to see Spirit energy and Nen constructs concealed with Inas well as traces of aura so faint that they might go unnoticed otherwise.
An alternative version of this technique gathers only the spirit naturally leaking from the body instead of the greater amount produced with Ren. This application of Gyo can still increase the amount of Spirit energy in one select body part and thus its power, but the output is much lower than what is obtained through the regular technique. It is unlikely this lower-consumption Gyo could counter In since Wing had all his students perform Ren. However, it has proven to suffice to see thin layers of Spirit energy and perform Water Divination correctly. In ( In; "Conceal") is an advanced form of Zetsu used to render one's Spirit energy imperceptible, effectively concealing it. Unlike Zetsu, however, In does not stop the user's aura flow; instead, it hides it, making it impossible to perceive with any of the five senses or extrasensory perception. Hence, this technique is perfect for launching sneak attacks or laying traps, as it can conceal not only the user's presence but also Nen constructs generated with Transmutation, or Conjuration.
The user can counter it by using Gyo in the eyes or through Zetsu. When In conceals part (or even all) of the user's aura output, experienced Nen users can divine their opponent is using it if an individual can feel little or no spirit energy from them in circumstances that would normally require it, such as during combat. En (, En; "Circle") is an advanced application of Ten and Ren. In Ren, spirit energy usually envelops only a small amount of space around the user's body. En is when one extends their Ren so that their spirit energy extends further than normal, then uses Ten simultaneously to contain and give shape to that spirit energy, normally a sphere. The minimum requirement is to extend one's aura to a radius of more than 2 meters (6.56168 feet) and hold it longer than 1 minute. Someone using En can feel the shape and movement of anything within the area covered by their spirit energy, with the degree of awareness and finesse depending on their skill level. Nen users can be told apart from regular people due to their stronger reaction to the En user's spirit energy.
Those who master En are typically able to extend it to a circle with a 50 meter (54 yard, 2 foot, 0.5052 inches) radius. The downside to this technique is that it is extremely tiring and draining for the Nen user to deploy so much spirit energy constantly. Shu (, Shū; "Enfold") is an advanced application of Ten. Shu allows a user of Nen to enshroud an object with their spirit energy, allowing them to use that object as an extension of their own body. For example, one could use Shu to extend their Ten around a weapon, which would strengthen and protect it. Shu can be combined with other techniques, such as Ko. Ko (, Kō; "Temper") is a combination of Ten, Zetsu, Hatsu, Ren, and Gyo in which all of the user's spirit energy is concentrated into one particular body part. Gyo is utilized to focus spirit energy on the body, while Ten is used to prevent it from dispersing. Zetsu is used to completely stop the flow of Nen in all other parts of the body, increasing the output in the desired area. With Ren, the amount of spirit energy is increased even further. This makes that one body part extremely powerful but at the cost of leaving the rest of the user's body completely unprotected. Due to the risk it carries, Ko is regarded as a purely offensive technique. An incomplete version of this technique can be utilized without Ren, primarily to master the other steps before increasing the amount of spirit energy to concentrate and contain. Some Nen users, Enhancers, in particular, employ Ko as a Nen ability by adding conditions to it. Ken ( Ken; "Fortify") is the advanced version of the basic Ren and Ten techniques. It is a primarily defensive technique where a Nen user maintains a state of Ren for a prolonged amount of time. The amount of aura surrounding the user's body during Ken is about 10 times higher than during Ten. Ken allows a Nen user to guard against attacks from any direction, but the large amount of spirit energy produced makes it tiring to maintain. It is considered the best option to defend from Ko, despite not being as powerful as the latter on any given part of the body, as it protects all of it evenly. When not immediately at risk of being struck with Ko, Ken is utilized to be cautious. Some Nen users choose to expand their radius to sense incoming attacks they cannot see, like a miniature En of sorts. Sometimes Ken is colloquially called Ren owing to the similarities between the two techniques. Ryu ( Ryū; "Flow") is the term for the use of Gyo from a state of Ken to perform real-time offensive and defensive value adjustments. If Ko devolves 100% of one's aura to offense or, much more rarely, to defense, and Ken splits it evenly between the two, Ryu is redistributing one's spirit energy according to any other percentage, for example, by focusing 70% of one's aura in one fist as one is about to strike, or 80% in one's leg to block an incoming kick. It is utilized to damage a Ken user without leaving oneself as unprotected as during Ko, although the technique's power is lower. Ryu is difficult to master, as it requires not only to control one's aura flow with great precision but also to be able to estimate the amount of spirit energy utilized by the opponent at a glance even if the technique is performed correctly, the movements of the aura spirit energy flow risk giving away the user's next move if they are too slow.
It really didn't take Vix long to fully mastered everything by the twenty-third floor due to him being able to farm a few times. Giving him the ability to use his spirit armor [ Neo Asura ] for long periods of time before he must rest and recharge his energy. Vix still didn't have a spirit weapon yet, but he did find a unique type of spear; also, his stats have grown as well as of now, Vix could be considered an 'S' rank hunter. The gap in power from an 'S' rank is three times stronger than an 'A' rank hunter.
As Vix was checking his equipment and loot, he spotted Alex with two teenage girls; one had auburn color hair with yellowed colored irises while the other girl's irises were of a crimson color with dirty blond color hair.
Alexandra spotted Vix, making her dash towards him with the twins in tow. Vix and Alexandra braced each other in a warm hug as it has taken each at least seven months to get to the two hundredth floor.
Alex introduced the twins telling Vix that the taller of the two with the dirty blond hair was Mori, who was a conjurer with the Nen ability to create barriers to imprison or protect herself or a group; the one with the auburn hair was Tia was a transmitter with the Nen ability to transmute her energy into all kinds of poison defeating enemies instantly or slowly.
Vix could only smile as he was a little excited to have two new, promising group members. as Vix was welcoming the new members and catching up with them, Levi and nate appeared from the girl's shadows, scaring them only for Levi to get slapped by Mori, to only laugh at her reaction. Levis shadow control has gotten even stronger as he and nate also fully learn the Nen abilities transmuting his spirit energy into shadows. Levi told Vix how nate was an emitter giving him the Nen ability to turn his spirit energy into arrows to shoot at a ranged distance with precise accuracy.
The group that was once three has now turned into six, now having close combat, mid-range, and long-range hunters capable of taking on the rest of the tower and future adventures. A few moments after, everyone got familiar with each other. Vix laid out a strategy to the group on how the rest of the floors will be a PVP platform as to now instead of having to finish a floor by defeating a gatekeeper, each participant in the tower must collet keys, each participant is given a key upon entering the two hundredth floor, from this point on to complete the tower one must fight the floor masters upon this the participants original key will change its colors with white being the final color and black being the starter, all the way to the two hundred fifth floor. Also, participants can now use the coins collected as the two hundredth floor is like a huge town; basically, a living area for those who wish to stay in the tower as they have nowhere else to go.
