Scarlet spreads her Chakra all around the body and goes into the water surrounding the waterfall(outer region).
She observed that she was getting wet because of the water.
Scarlet thinks 'I need to increase the Chakra density and also make sure that I don't waste too much of Chakra'
Scarlet concentrated more amount of Chakra on her body and she noticed that less amount of water was touching her. She sat down in meditating posture and slowly increased her concentration and prevented the water from touching her.
After practising for eight hours she finally managed to isolate water from her body completely using Chakra.
She then went felt hungry and went to the forest to hunt. After some time she finally managed to hunt a deer, she cooked it up and ate it and took some rest for a while.
After eight hours of practice, her Chakra was nearly depleted so she slowly started to restore her Chakra. After her Chakra was restored she made 5 Shadow Clones for the practice. (She cannot use more because the area around the waterfall is not sufficient )
She now went little closer to the waterfall where water was moving and started practice. She noticed that some water was moving inside the barrier because of the movement of water. She started to strengthen the barrier by adding more Chakra to it and increasing the density again.
After a lot of changes, she finally managed to make it better. She then took some rest and started to recover her Chakra. Next, the went into the central region of the waterfall where the waste was falling at very high speed. She could not endure the pressure of the waterfall and started to use Chakra to protect herself but no matter how much she tried the water easily penetrated and hit her and sometimes it even broke the barrier.
Scarlet kept on trying again and again but always failed. After two days of failure, she tried to think about an alternative solution.
Suddenly an idea crossed into her mind ' If one Armour is not enough then why not use more '
She slowly recovered her Chakra and went to the centre of the waterfall. She surrounded her body with Chakra to endure the pressure but the water was entering through the Chakra barrier. She then started to form another barrier which failed.
She finally managed to make the second cover of Chakra on her fourth try.
She noticed that although the pressure has decreased a little bit the water was still breaking in her defences.
She decided to increase the number of layers to 3. She then started to create an additional barrier but it was failing after trying for another four hours she finally managed to make three layers of Chakra covers.
She decided to compress them and increase their effectiveness. She started to compress the layers and after two hours she finally managed to do it.
She noticed that the weaker water current we're not able to penetrate her defences anymore but the stronger water current was still troubling her.
She was very exhausted by now as she started thinking ' Damn, there is only one day left for the time given by Tsunade (1 week) to finish but the jutsu is still not finished what shall I do now. '
She started to refer the defence techniques of Konoha for inspiration, when she was reading some defence techniques she suddenly remembered about Neji's Kaiten. She then thought 'What if I rotate the Chakra' and got excited. She started to recover her Chakra even though she was exhausted she was still trying to complete the jutsu as only 1 day was left.
After one hour she finally managed to recover her Chakra and a little less exhausted. She started to make three layers of Chakra cover and then she tried to rotate the outer layer in a counter clockwise direction. Even though rotating the Chakra around her body was difficult she was little familiar with rotation because of Rasengan so was not too much troubled.
After two hours she managed to make the outer layer of Chakra rotate, she noticed that most of the water from the strong current was blocked due to the rotation. She decided to give the jutsu one last push so that it can withstand the enemy attacks effectively.
She then tried to rotate the Chakra in the second layer in Clockwise direction. It took her a large amount of concentration to ensure that the rotation in the second layer does not conflict with the first one.
After five hours she finally managed to complete the jutsu. She noticed that all the water surrounding her was rotating in a counter-clockwise direction.
If seen from outside the person will surely ask "Hey!, what is that girl doing in the centre of the whirlpool ".
She came out and thought 'Well let me just give you a simple name Hmm let it be 'Triple Chakra Armour' '.
Scarlet then made 5 Shadow clones and made them attack her to test the effectiveness of the jutsu.
She first clone who tried to punch her after contact with her armour flew in the left direction and turned into smoke.
After some attacks, she confirmed that physical attacks were useless against her. Now she asked her clones to attack her with second stage Rasengan.
The clone attacked her with the second stage Rasengan. After the collision, she noticed that the outer layer of her broken and the second layer had some cracks in it but the third was still effective.
She dissipates her clones as suddenly she falls down due to over-exhaustion.
