This bizarre ancient martial art, which clicks on acupuncture points to cause internal explosions within the human body, might not concentrate internal energy to the extent that modern chips can, but its unique factor is something all opponents dread.
As long as the acupuncture points are hit, there's no need to actually channel the internal energy into the enemy's body. The same acupuncture points can produce completely different results depending on the force used and the angle taken.
If Julion Johnsons didn't have a chip inside him that could superbly control his internal energy, he would have probably been punctured to death by Julion Johnsons in just the previous rounds of attacks.
Julion Johnsons too had his weaknesses; like his biochemical beast name, the Giant Scorpion, all ten fingers carried poison. This was the poison technique of the Thousand Poisonous Scorpions Hand, quite akin to the legendary Thousand Poisonous Spiders Hand.
