N-NINE!?

[Sense]

[5 Star Ability]

[Description: When activated, the user will be able to sense everything around him. The range will depend on the user's MP (1 MP = 1 meter).]

[Note: The ability will be activated automatically if someone is deliberately hiding his/her presence and is in the detection range of the user.]

[Note: The ability will fail to detect the presence of a cultivator who is concealing his presence and has 2 times more MP than the users]

[Conceal]

[7 Star Ability]

[Description: When activated, no one will be able to sense the user's presence or see him if the user doesn't wish for it. Only a cultivator with 3 times more MP than the user can detect the user's presence. Or else, the user can only be detected if he touches or is touched by the user.]

[Note: If the user's killing intent is detected by a cultivator, the effect of the ability, [Conceal], would wear off]

'So that's it…'

Nux finally realized.
