An hour later.
"Brilliant! A brilliant secret technique! The creation of a genius!"
Ling Feng clicked his tongue in admiration, feeling that the creator of this secret technique must definitely be a genius!
Of course, the reason why the robed elder could create the "Qi Refining Mixed Element Lock" was also due to his own extraordinarily high realm of perception. Without that realm of perception, an ordinary person would never be able to invent such a cultivation technique.
"Humph humph!" The robed elder's mouth curved into a slight smile, obviously very pleased with Ling Feng's admiration.
Ling Feng slowly opened his eyes, took a deep breath, "So, this is Qi Refining."
The so-called Qi Refining, as the name implies, is the refining of True Qi.
The robed elder's idea was to implant eighteen Mixed Element Locks within the body, using them to lock in True Qi, thereby tempering the cultivator's True Qi, forcing it to undergo endless compression.
