Day per Ten Thousand 

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.

Lu Li felt nervous as he looked at the entrance of the cave.

Bai Jinfei led a group of people and slowly entered the cave.

The person behind Bai Jinfei was a middle-aged man in his thirties. He had a pale face and was elegant and handsome. He was dressed in green and carried a white sword. His eyes were like stars and he looked like a celestial being that had descended from heaven.

A purple-masked elder was beside him. He had a powerful and frightening aura. He was also a demigod.

A group of people followed closely behind them.

Their eyes met, but they did not say anything.

"Junior Brother Li, Congratulations!"

The green-clothed middle-aged man cupped his hands and congratulated him casually.

"You're welcome, Hell Master. Please take a seat."

Demonic Devil narrowed his eyes and waved his hand casually. He did not stand up to welcome him.
