Humans were carbon-based lifeforms, and the biological macromolecules in the human body contained carbon elements.
Silicon elements and carbon elements were on the same row in the periodic table and had similar properties.
Silicon-based lifeforms' biological macromolecules had silicon atoms in place of carbon atoms. Their bodies were several hundred times tougher than carbon-based lifeforms and had longer lifespans. They could live to over 1,000 years old at least.
Such an inhuman race could naturally not be dealt with using regular martial arts principles.
Weak points that could be lethal to humans were completely useless against this silicon giant.
No matter how tough Feng Lin's fists were, they were still just flesh and blood. The toughness of silicon-based lifeforms' bodies surpassed even that of most alloys that humans had.
Wanting to use a pair of fleshy fists to crush the other party was like using tofu to smash rocks—courting death!
