After upgrading Soul Technique to level 1000, John's soul strength had reached the True Soul tier, and he had unlocked a new offensive skill—Soul Impact.
With his current soul strength surpassing that of most tier-seven legendary powerhouses, he could now use Soul Impact to easily kill them.
Only a few tier-seven experts who had cultivated their souls beyond a thousand points could stand against him.
The most terrifying aspect of Soul Impact was its ability to deal irreversible damage to the soul. In other words, if John wished, he could permanently annihilate a player's existence in the world of Gods.
However, he didn't plan on using this skill against players lightly.
After reaching level 1000 in Soul Technique, each subsequent level would require 1,000 skill points, yet the increase in soul strength remained only +1 per level.
