Shinobi

"Shinobi from the first have been utilized by
generals since ancient times with a great
emphasis. It is the case that one and their
strategy can destroy tens of thousand of enemies,
attain virtue and achievements, or make one's
way where there is no path. Even if you try to
block one with an iron gate, they can outwit you
in such a skilled way, as if guided by a divine
power. None could do better than them."
