Lethal Qi Accumulation Technique.
That was the cultivation technique recorded on the human skin paper.
To be precise, it was a secret technique.
The method of cultivating this secret technique was also quite unique.
It involved a peculiar visualization method, imagining oneself in a state of near-death, a deathly stillness.
Then, from that state, one would comprehend a deadly and lethal Qi that could annihilate all living things.
According to the description in the secret technique, this deathly lethal Qi was immensely powerful and could greatly harm the vitality of any living creature, rightfully calling it a true technique of slaughter.
It sounded relatively simple, but in fact, the cultivation of this secret technique was exceedingly perilous.
Especially the part where one had to visualize oneself in a state of deathly stillness—a slight carelessness could lead to actual death, never to awaken again.
To kill others, one must first face one's own death.
