Mokuton, manipulation of wood, one of those other
combination elements that he'd seen at least once before, although with much less of the killing intent and in a smaller quantity. Neither were shocking though, if they could generate life, even in that limited style, as easily as he could manipulate water, air, and draw out temperatures then it would probably be pretty trivial to make this much of the stuff. It did seem odd since the mass was much more than what he ever produced but there was probably some method of stretching their chakra into so much material that the Senju bloodline classification employed that he wasn't privy to...so he earmarked the subject mentally to return to it when he was back in front of his books. Maybe it worked like medical jutsu where you just stretched something you already had...
The medical attention he would've required had he actually been struck by them would've been a good mental segway but he was already outside of their reach, replacing himself with a rock as he hadn't much time to be creative in that regard. Shame he couldn't have at least used a poisoned rock with sharp edges but these were improvements to be attempted in later combat situations, for now he had retreated somewhere dark, dim, and out of sight behind the structure he was defending, throwing out a clone of himself crafted from the ice and winds he was previously comparing to the woodwork. With some luck the switch would make things a bit disorienting, from the enemy's position in the tree line they likely didn't have a great view of things and replacing himself with his clone would've been better but he was a bit stuck on the immediate response of not being run through by angry tree roots.
While his fresh-faced clone deliberately used both of his hands for its seals, Yukiin didn't need to and hopefully, that act would pay off later in a bad assumption about his multi-tasking abilities. His weapon of choice was in one hand, animating strings bringing one of his puppets to life as several of its gears and mechanisms clicked into place, a handful of its dangerous weapons arming as the puppet affixed to his back, Shirudo, also began its work of cycling through his blood and chakra system. The funneling of energy was something he hadn't yet done in a fight before and it made him a bit woozy, having the machinery work through his flesh as an extension of himself was uncomfortable to say the least but since he didn't have a Sharingan or Byakugan or anything of the like he had to rely on mechanical aids to make himself 'more than human'...well besides his bloodline abilities but that was sort of par for the course for a shinobi.
Tsurara remained concealed for the time being with it's wielder as his clone finished its task, drawing down the rain in a heavy storm and speaking on his creator's behalf.
"Mokuton is tough, always wanted to see who would win..."
The clone whisked up the winds around itself, drawing the rain forth into a solid stream of forming ice until the sharp-edged form of what was previously known as a Wind Scythe was created, barreling out at the completion of its seals towards the tree line and towards the perceived origin of the attack. Whether they were there or not it was impossible for Yukiin, or his clone, to know but if this jutsu required him to stay put them he might get a lucky break and cut into him.
"Ice as sharp as a diamond or wood as strong as iron."
He wasn't lying, he was curious, but he felt like he already knew the answer. The saying was that Hyouton was as strong as steel after all, so what could iron offer against it?
