While Tenzin walked back to his side of the wall, he figured now was a good time to practice some impairing techniques. With the next slate, the young man wanted to practice a jutsu he had been working on that would pair with a jutsu he had read about. For this the young man wanted to make sure that he could breathe in bad situations that wouldn't necessarily give him the opportunity to breathe naturally. This was something that Tenzin would need if he was to pair a couple of jutsus together along with fighting other shinobi that would try to take away his breathing.
With his back against the wall, the blue eyed shinobi started to focus his chakra. This time he made sure to focus around his mouth. The chakra itself merged with the fuuton affinity. For this instance, Tenzin wanted to make sure that he was familiar with the hand signs. Within a moment Tenzin weaved the hand signs required to perform the jutsu. After the last sign was met, he held it while expelling his chakra. The fuuton chakra formed around his nose and mouth. The spiraling wind formed a filter of some kind.
As the wind around his mouth and nose moved at a fast pace, doing its job essentially, Tenzin moved on with performing the next jutsu. While the mask was covering everywhere he could breathe, the shinobi continued to focus on his chakra throughout his body. With the chakra that was already merged with the fuuton affinity, the young man pushed forward with the next one by weaving hand signs.
When the Anbu Captain finished the last hand sign, he held the last sign like he had done with the last jutsu. With Tenzin's chakra expelled outward from his body, the wind would push forward away from him. This wind would essentially push all of the oxygen forward. As the winds spiraled around, it would take most of the oxygen away. In a normal instance, Tenzin would have to hold his breath in order to not lose his whereabouts or consciousness.
With the chakra being controlled by Tenzin, he moved his hand to his kunai and held it in his right hand. With the wind spiraling around his nose and mouth, Tenzin was breathing perfectly fine. This allowed the man to make a fast movement towards the training dummy. With 30 speed, he flashed his way to the training dummy and appeared right in front of it. He struck the training dummy with his kunai and hit the chest of the wooden training dummy. The kunai would be pushed through almost through the other side. Thanks to the previous jutsu, the kunai broke through fairly easily.
After the kunai went through the other side, Tenzin would twist his body with his right leg out. The young man would swing his body to the right with his left leg lifted in the air. The momentum itself allowed Tenzin to swing his right leg in a fast manner. The right leg would be swung around and landed on top of the training dummy. Connecting the leg with the training dummy pushed the training dummy back a little bit, however it still stood up. This simple thing annoyed the man, and with anger he pushed forward more.
He planted his right leg after the kick to the ground. Using the momentum, he pushed himself forward. With the same speed as earlier, Tenzin sent himself towards the training dummy. He tackled the training dummy to the ground sending it to lay there as if it was another shinobi. Although in a real battle this technique could cost him his life, what he truly wanted to do was test his movement and make sure he could move properly under the conditions he would lay out for himself in the future.
Tenzin stood up and stretched his back before walking back to the wall. The young man walked over to the wall and focused on his chakra. By doing so, he dispelled the winds within the area first. For now he would leave the mask on since it would take a little bit of time for the oxygen in the training room to fully return.
What Tenzin didn't realize was that by releasing the final hand seal early, the process of oxygen had already been started. This sudden moment of clarity caused Tenzin to hit his head slightly with his left hand. He felt a little bit foolish since something so important as that detail should have been memorized. With a little bit of shame, Tenzin released the chakra from his face as well. By the time he released it, the oxygen had been flowing properly. With this new found combo, Tenzin had felt that he was ready to move on to the next few jutsu. He wanted to fully master Fuuton and then move on to another element.
Fuuton • Alternate Breathing
B-Rank Ninjutsu
After weaving the necessary hand seals or channeling chakra, the user focused their chakra to their mouth. A wind film covers their nose and mouth and almost has a spiraling movement to it. The futon around their mouth acts as a filter and replaces carbon dioxide and harmful gasses into oxygen. This technique appears at a speed dictated by the [Control Stat] and lasts for [4/Control] posts.
*Fuuton • Gentle Caress of Suffocation
A-Ranked Fuuton Jutsu
Once the user has performed the required hand seals, it is recommended that they take a deep breath. This is because their fuuton chakra will visibly surge outward to cover an area of 65m in all directions around their person. While this does not create a vaccuum or remove all the air, it does push specifically all of the oxygen out of the area and keeps it that way for 4 posts, though the duration can be extended if the final hand seal is held. Note that extending the duration will incur additional chakra costs. This technique causes all who remain within this area to lose 5 Endurance per post that they do not escape it. If they reach 0 Endurance, they will black out. The Endurance regenerates at a rate of 5 per post that they are outside of this technique's effect.
