Taoist Priests Cultivate Immortality and Are Invincible in the World

I, Great Flame Heavenly Master Zhang Qingyuan, have passed away. After living for 180 years and slaying countless demons, no immortal came to guide him. The judge of the underworld said that I have profound merits and will be reborn into a good child. Then... I was reincarnated into a world with true spiritual energy with my memories. Then test the spiritual roots - there are no spiritual roots. Oh. Without spiritual energy in my previous life, I would have been invincible. In this life, Taoist priests who cultivate immortality are still invincible in the world!
