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.

Upon hearing the system notification, Lu Li felt excited.

After 10 minutes, he should be able to break through to the fifth level of qi refinement realm!

"Alright, I still need to train harder to advance to Immortal stage."

Demonic Devil waved his hand as he said, "Yao Yao, you'll be in charge of the congratulatory meeting in 3 days. Jinfei, send out the invitations. As for Lu Li, you just caused trouble, so it's better for you not to go out and stay in your house. 3 days later, someone will probably come looking for trouble. Go now."

As he spoke, the blood-red fish spat out a pile of golden invitations and landed beside Bai Jinfei.

They cupped their hands and bowed. Then, they turned around and left.

Thunderous sound rang out and silver lightning flashed. The door was seal after they left Demonic Devil's cave.
