Lu Li transmigrated and became an apprentice in a Demonic sect. He was also given the Martial Art System.
He could automatically cultivate any technique as long as he learned it.
But.
[Your Blood-Devouring Demonic Technique is feeling sad as it has not absorbed human blood. Cultivation level decreased.]
[Your Heart-Shattering Palm Technique is not satisfied as you have only been killing animals. No progress with its cultivation level.]
[Your Seven Kills Fist Technique is very dissatisfied with your kind heart. Cultivation level decreased.]
[Your Ghostly Steps Technique does not have enough energy as you have not fused with the soul of any ghosts or spirits. No progress with its cultivation level.]
......
Lu Li had no other choice when he read the system notifications.
Thus, he started to cultivate orthodox techniques in the Demonic sect.

Laughter suddenly echoed in the silent hall.

He was sitting on the white bone chair, and he stared at Flying Fox Monster as he said in a strange tone, "Flying Fox Monster, I'm sorry! Lu Li, my useless disciple, was careless and killed your disciple. You won't be angry, right?"

After hearing this, Flying Fox Monster's purple face turned red with anger.

"Hmph! Demonic Devil, this disciple of yours is amazing!"

However, Flying Fox Monster was someone who had lived for more than a thousand years. After he snorting coldly at Demonic Devil, his expression was calm.

As he was speaking, he was about to take care of Hu Fei's corpse.

Suddenly, black flame burst out from the stone slab in the hall, burning Hu Fei's corpse.
