As his opponent would vanish, lessening the damage of the Amaterasu, Ichirou would move from his location, to prevent being caught even in his invisible state, he knew he had to regroup. And a different Idea came to mind. Reaching into his shirt through the collar(though this would be unseen) he would retrieve a scroll from within a harness underneath his outerwear, he would extend his arm outward, and form the seal of confrontation. Causing an Ethereal barrier to spread throughout the zone,
Kekkai Genjutsu: Sea of sands eternity
A Genjutsu barrier formed by his Kuchiyose which Ichirou sealed into a scroll to assist with combat efficiency, this barrier would quickly spread throughout the zone, Once caught inside, anyone with a chakra signature whom did not possess a barrier pass, were caught within a tight continuous Genjutsu, which would effect the world around them as well a their mind in two ways. First it would effect the eyes, making the area around them (within the barrier) appear to be a sea of sand, fluctuating like water, the sand would billow over them and swallow them within the waves of sand, only to spew them back out. Secondly the Genjutsu would effect perception. Time would be slowed to the victim, every 1 second real time, would last for 10 seconds within the Genjutsu. The downside of this barrier is that in order for Ichirou to expand it to the entirety of the zone, the barrier would only last for 1 turn before expiring, unless a steady chakra source was funneled through the scroll to continue the Jutsu. However Ichirou was not aware of his opponents actual position currently, and had to take this risk of shortening the length of the barrier to make sure that his opponent was caught within. Once the barrier was activated Ichirou would lighten the weight of the scroll, leaving it to float in the air.
Doton: Keijūgan no Jutsu - Earth Release: Light Weight Rock technique
This would take not even a moment, as Ichirou already had his hand placed on the scroll when he activated the barrier, leaving the source of the barrier floating in Air Ichirou would maneuver away from the scroll, and form the snake seal, kneading chakra into his stomach
Mokuton: Kajukai Kōrin - Wood Release: Advent of a World of Flowering Trees
Ichirou would build the chakra for his Mokuton technique within his stomach quickly, ceasing his Miseigakure no Jutsu and activating his Rinnegan as he did so, and spew it out in the form of three large seeds, which would strike the ground in a triangular shape within the barrier and sprout small Mokuton Forests, all bearing beautiful pink flowers. This flowers would exist in abundance upon the 7 foot wooden panels they were spawned upon, As soon as these flowers would spawn they would immediately begin releasing a thick yellow pollen which would quickly fill the zone as the forests sprouted, though Ichirou kept it beneath the tree tops with his chakra as to prevent himself from inhaling it. Whenever this pollen is inhaled, it causes the victim to become rendered unconcious for an extended period of time. As the Forests would spread Ichirou's main goal was to incapacitate his opponent at this point, his chakra levels were getting lower by the moment and he needed a way to succeed. With his opponent more than likely caught within the strong Genjutsu of the barrier, he would be unaware of the incoming pollen. Ichirou knew that his Sage Mode shouldn't be lasting for much longer, so hopefully this would seal the deal. The Genjutsu of The Sphinx were difficult to break, even for bearers of the sharingan. It had nearly incapacitated Ichirou whenever he had first encountered them. As his Jutsu would continue to expand Ichirou would take a chakra pill, to restore his chakra (on the next turn)
