Recoil is a side effect that all warriors often experience when hitting someone or something. The recoil force will become stronger when two combatants clash in close contact. When it is strong enough, it may even create a shockwave phenomenon.
Recoil force is quite dangerous for anyone if not treated carefully. One body will break from the recoil force if not taken care of properly. Most of the time, the warrior has a sturdy body to minimize the recoil effect.
Another method is using proper skill or stance to redirect the recoil effect. A person with superb body control like Angus, could even shift the recoil force to the enemy or his surroundings.
In short, it is a force that couldn't be avoided by anyone, even the legendary seventh-grade people. Yet, Patimura witnessed an absurd phenomenon about recoil force.
The unknown grotesque monster in front of him seems to break common sense and completely ignore any recoil force.
