"Hair" is divided into six series, namely "Enhancement System", "Release System", "Change System", "Operation System", "Embodiment System" and "Characteristics System". Because each person has different qualifications, personalities, and growth environments, they belong to different departments. One can lightly develop the mental ability of the department to which one belongs, but it is not easy to cultivate the mental ability of the non-affiliated department. The specific difficulty can be seen in the six-series diagram, and the farther away from the department you belong to, the more difficult it is to cultivate. In addition, if you put some kind of restriction and vow on yourself while practicing, the completion rate will increase, that is, the stricter the constraints, the higher the completion rate.

Reinforcement system

Enhance the original nature of oneself or the weapon. A system that can be used to the extreme of attack, defense, and healing. People who belong to this line can inject thoughts into different objects to get effects that increase their strength, such as Xiaojie's special move? Guess the fist is to inject the mind into the fist to increase its attack power; The strength of Finks' punch depends on the number of turns of the arm, and the more turns you make, the stronger the force. And after injecting the thought into the sword, it can also be made into a sword that is close to folding. Those who are proficient in strengthening the ability can reach the limit of human beings, such as Cheng Dù, who is only physically painful when he is hit by a bazooka against a chariot.

Release system

Qi can still maintain its power outside the body and can be sent away from the body. Releases the body's qi. The emitted gas can change appearance, attack enemies, or carry out commands. Anyone who wants to act on Qi outside of the body will use these properties, and the farther away they become, the more obvious they become, and with practice, they can even teleport (Leoli, Golienu). This type of attribute is the most commonly used by the Mindful Beast. The main attack methods of the release system are telekinesis, such as Franklin's two-handed machine gun, Leiza's dodgeball, etc.

Operational system

You can inject your own thoughts into the object to control them (if you inject them into others, you can control them). But good handling of objects requires a lot of practice and skill. This kind of attribute is used as long as it is used to control objects other than oneself (living beings, energy), and in addition, such properties can also be "automatic", for example, the tape of "gold" is pre-set conditions to "automatic" activate the mind. If the ability to operate is focused on manipulating the human body, most of the people with the ability can also manipulate themselves; Ilriddle, both Chivalry and Petor can do this, and in this state their physical abilities will be exerted to the limit, but it will not last long.

Variation system

The nature or shape of the qi produced can be changed (e.g., Killua changes qi into electricity to attack, or Gilnuo changes qi into dragon shape). When Qi is connected to one's body, it is extremely powerful, and once it is detached, its power decreases dramatically. These properties are used as long as they change the nature of the mind, but no matter how they change, they still retain the nature of "energy". In addition to the nature of the qi changes by himself, he can also shape a variety of tools, such as Mo Lao Wu can shape the qi that changes into smoke into breathing tubes, rubber boats, ropes and stand-ins; Sisoka can pull qi into a glue-like shape, and March can turn qi into filaments that extend infinitely.

Embodiment system

You can transform the form of your qi into what you want, that is, you can materialize your qi, and you can use it to create real weapons to attack. Theoretically, anything (matter, space, mental ability, consciousness) can be manifested, and usually the embodied object will disappear as soon as it leaves the body, but with practice, the conditions for disappearance can be set (and the advantage of "free retraction" will be lost). Weapons that appear as gas embodyments are usually not simple weapons, and most often have unique abilities attached, such as a small droplet vacuum cleaner that can suck up any inanimate object; The Kupi forged object has a round characteristic, and Kurapika's middle finger restraint can force the kidnapper to be locked in a desperate state.

Trait system

Mental abilities that do not belong to the above five lines are all classified in this category. Trait abilities are mysterious, such as Kurolo's ability to steal others' telekinesis, Paike Noda's memory reading and ejection, Nion's prophecy ability, and Aluka's wish-granting ability.
