Tagorihime had lived for a very long time. As one of the three great Snake Princesses under the White Snake Sage, she considered herself highly knowledgeable and experienced.
Although she had not appeared in the Shinobi World for many years and had no interest whatsoever in its changes, spending every day in Ryūchi Cave waiting for humans to wander in so she could eat them.
She still knew plenty of the most basic, core intelligence.
For example, Sage Jutsu.
She had never seen anything like this before!!
Expending one's own Chakra to create real, tangible clones? Fine, that was unusual, but nothing more.
The original body absorbed the life force of those flesh-and-blood clones, then used it to acquire Natural Energy?? Oh, so Natural Energy could also be taken from living creatures. That meant that, so long as one mastered the method, one could slaughter indiscriminately and create massacre after massacre to gather enough Natural Energy.
Although this fourth method of acquiring Natural Energy, independent of the three major systems, was exceptionally savage and bloody—each Immortal it created would leave corpses strewn everywhere, causing countless lives to die miserably and become materials for extracting Natural Energy—none of that mattered. Tagorihime did not care how many people died.
Tagorihime was shocked by this fourth method, left dumbfounded by such a genius-like innovation.
But what happened next was something she could not understand at all.
He created clones himself, drained those clones to death to gain Natural Energy, then combined that Natural Energy with his body and spirit to create Sage Chakra, before using that Sage Chakra to create a whole pile of Sage Mode clones???
???
Human, there was something wrong with you!
Maybe it was an illusion, but something felt seriously off!!
Self-production and self-sale?
No, this was even more
