Sword techniques.
This term is familiar to every sword cultivator. When first learning the sword, basic sword techniques are something every sword cultivator trains in and starts their journey with.
However, as cultivation progresses and sword intent levels continue to rise, almost no sword cultivator deliberately delves into sword techniques or spends significant time on them anymore.
Everyone allocates their time to cultivating techniques and comprehending sword skills instead.
Sword techniques, naturally, are no longer a focus for study.
Most sword cultivators, subconsciously, begin to believe that investing time in sword techniques has low returns.
Rather than spending time honing sword techniques, they think it's better to use that time to cultivate their techniques and improve their sword skills.
And so, over time...
Netherworld King himself fell into this trap.
