"Haha, looks like we really got him worked up this time!" Ruri said with a laugh as he looked at Chōza Akimichi.
"Oh, right, why can you use Ice Release, kid? We thought you only knew Wind Release and Fire Release!" Shinnosuke Sarutobi asked, looking curiously at Ruri. A few days earlier, during Ruri's fierce battle with the Eight-Tails, he had used Ice Release. They could hardly forget that.
"Well, you probably wouldn't really understand even if I explained it. When you control a flame's temperature and bring it down to zero degrees, you can turn the flame into ice!" Faced with their curious gazes, Ruri could only make up an explanation they were unlikely to believe.
"What? Controlling a burning flame so it stays at zero degrees? How is that possible?" Shinnosuke Sarutobi asked, looking at Ruri in astonishment.
"Keeping it at zero degrees? That isn't impossible. There's a theory that combining them can also produce Ice Release!" Yamato said thoughtfully.
"Being able to keep a flame at zero degrees would take incredible control! But you actually managed it, kid. That really surprises me!" Chōza Akimichi said to Ruri with a smile.
Combining two chakra natures could produce a third, but that was only a theory. In reality, after Hashirama Senju, Konoha had conducted so many experiments, yet Yamato was the only Wood Release ninja they had successfully created.

The concept of Yin Release, however, was to draw on imagination and spiritual energy to create matter from the intangible, while the concept of Yang Release was to draw on the physical energy of living
