Using spiritual power for long-range attacks, even if one expended tenfold effort, it was very difficult to achieve the power of onefold. Therefore, martial artists of the same realm avoided life-and-death struggles with this method to probe each other. If they found themselves outmatched, they would immediately retreat.
Only when facing opponents at least a whole great realm below oneself would this blast of spiritual power fulfill its intended purpose.
But when martial arts techniques were activated, everything changed!
Martial arts techniques could condense spiritual power, not only preserving its might but significantly enhancing it. The higher the level of the martial arts techniques, the more terrifying their power.
The "Lone Wolf Howl" of the old man in red was a lower-grade Heaven-Level martial arts technique, which he had obtained at great cost from an ancient ruin, capable of increasing his battle power by more than a small realm.
