My Spiritual Root Is the Peerless Female Devil

The female demon king who shocked the fairy world thousands of years ago came back from the dead, but unexpectedly became the spiritual root of Jiang Ning, a disciple in the Qi refining period. As long as Jiang Ning continues to practice, the Demon Lord will be able to obtain the demonic energy from him, thereby controlling his body and gaining freedom. Jiang Ning woke up and traveled to the world of cultivation, but was forced to obtain the spiritual root of the female devil. Fortunately, he has awakened the [Didi Cultivation System], and by binding the genius through the system, he can share his cultivation with the other party, thus fighting against the female devil who wants to corrode him at all times! Jiang Ning: This genius, I have the supreme bone of a demon king, and I will give it to you for free. That genius, this is the soul-eating treasure lotus that blooms once in a thousand years in the devil world. Quickly take it to make elixirs. That guy over there, why did he sleep at three o'clock in the morning? He quickly got up to practice... Female Demon King: Jiang Ning, don't be lazy yourself, practice quickly! Everyone: What's wrong with this world?
