Assimilative

The highly realistic excruciating pain had crippled Ieyasu's defense since his subconscious mind refused to allow him to defend properly, insisting that he avoid confronting it.

Thus, Ieyasu simply obeyed. He switched gears, using a maneuvering Martial Art that he had copied in the past year to confront Rui with evasion as a solution to his offense instead of defense.

WHOOSH WHOOSH WHOOSH

Ieyasu effortlessly weaved away from Rui's strikes with ease. Rui narrowed his eyes, pain could only be generated if his strikes landed on Ieyasu, which was a requirement for the pain to be realistic and believable.

He had gone on to add illusionary elements that mimicked impact that made his body feel rocked by force the same way it would if it had been struck by an actually powerful force of the same caliber as the one he was pretending he could launch.

Yet if Ieyasu simply evaded the blows, then the technique was useless.
