Although Grandmasters were forces to be reckoned with, their impact on the world had been greatly reduced since the introduction of firearms. Any ordinary man could kill a Martial Artist with a gun and merely a dozen well-armed and well-trained soldiers were able to corner a Grandmaster. Even those who were at the top three spots of the Dark Roll could not face the American Military head-on.
The advancement of modern technology had made modern military weapons extremely deadly. However strong a Martial Artist was, he could be laid low by a high caliber bullet, so would Grandmasters under Cannon fire. Those were just the regular arms, not to mention the superweapons, such as nuclear bombs. Therefore, no Grandmaster, let it be those in China or Kendo Grandmasters in japan had the audacity to challenge the authority of a nation.
The more powerful a Martial Artist was, the more fear they had toward superpowers on this planet.
