Well.. If it's moving, yes. If it's static, an unmoving object. I did say no. Untill it moves, that is. If it gets created while the blades are out, it would trigger.Just thought of another question: If there was foreign chakra in th air before the technique was used would the blades instantly trigger upon creation? Also it works for any amount of chakra beyond the normal one circulating in our bodies, right?
Seeing the human grizzly bear representation that is you I initiate an attack. I materialize multiple blades composed of chakra all around you. The bales cover all possible angles besides the earth that you stand on. The blades are created a few meters away from you and due to their visibility and excess in number they would block your view from myself. Exploiting the situation I dash in a clock-wise manner while still maintaining a mid range distance from you. I would stop when I am towards your back. Whilst running I would have performed several hand seals and created a earthen swamp beneath you. The swamp would negate the only visible path of survival which is the ground. Inversely, due to my view on you being blocked as well the swamp would serve as a safe card. If by some feat of behemoth strength you managed to dig deep into the ground without the use of chakra the swamp would deal with it nicely.
(Doton: Yomi Numa) - Earth Style: Swamp of the Underworld
Rank: A
Type: Supplementary
Range: Short/Long
Chakra Cost: 30
Damage Points: N/A
Description: The user will first perform Boar → Tiger and then by changing the surface of an object beneath an enemy into mud and creating a non flammable swamp, the user can sink his enemy into the mud. The adhesive, chakra-infused mud ensnares the enemy's body, making it almost impossible to recover one's strength and escape from the swamp. The size and depth of the created swamp depends on the user's skill and the amount of chakra used, but if the user is an expert in this technique, it will always be possible to make a fair-sized swamp which is extremely effective against a great number of enemies or when having to face gigantic creatures.
