"The goal of this technique is to blow an updraft from below, lifting the bird into the sky," Kamiya Yunxiao said.
"Yes!" Kamiya Keiyun nodded. "That way, as long as it's lifted high enough, the rest of the journey can be handled by gliding."
"But I don't think that's good. Wouldn't that make the wings of the bird you transform into purely decorative?" Kamiya Yunxiao said.
"That's exactly how it is. I only transform into a bird for camouflage. If transforming into animals didn't make it easy for hunters to catch me, transforming into an animal would be more suitable!" Kamiya Keiyun explained.
"That would require far too much thrust. Even if Shadow Clones are more efficient at using ninjutsu, you can't exploit them like this!" Kamiya Yunxiao shook his head. "I do have a suggestion, though. You could transform into a Fighter Jet!"
"Hm?" Kamiya Keiyun froze.
"It can still have the shape of a bird, but the wings should be designed like those of a Fighter Jet, with D-shaped wings!" Kamiya Yunxiao said.
It was true that he was an agricultural student, but this was not knowledge reserved for aerospace majors. In fact, basic fluid mechanics had already been taught in high school.
Kamiya Keiyun simply had not expected that he would ever get to use it.
"The faster the airflow, the lower the pressure. As long as the wings are shaped like a D, the air flowing over the top will move faster than the air below, generating upward lift. That will reduce part of my workload!" Kamiya Yunxiao said.
"Sure, no problem!" Kamiya Keiyun said. "Come on, let's experiment. You study the lifting technique, and I'll study the airplane Transformation Technique!"
"Lifting technique sounds way too awful!" Kamiya Yunxiao said speechlessly. "I'm naming this technique: High
