Lu Zhen's consciousness slowly made its way to his brain in a snail's manner.
He had noticed one thing while trying to initiate the demonic cultivation technique: he needed to be more careful with his consciousness rather than speed, and if he could find a special balance between both speed and carefulness, it was even better for him.
The consciousness finally reached his brain, and Lu Zhen immediately tapped into his mental energy. Slowly but surely, the reason he had failed so many times previously was that tapping into his mental energy was a very hard thing to do, even when Lu Zhen fully focused on it. So, with his consciousness separated into two, its difficulty at least increased by a hundred times or even more.
Finally, after slowly but steadily trying to tap into his mental energy, he finally tapped into a single strand of mental energy that surged through his body.
