Even though he had never killed any living being in his life, his opportunities were constantly snatched away by immortals or cultivators who were favored by God. Even if he does good deeds, he will still be feared. Even if he loves someone deeply and swears for her that he will not do evil in this life, he will always be the one who is suspected without the slightest evidence!
Why? Just because he was born a monster, he is inferior to others.
Although he is just a pangolin spirit and has no immortal destiny, he is devoted to the Tao. Just because he is a demon, he will never become an immortal! It can only be a stepping stone for others! Just cannon fodder that can bring out the glory of the protagonist!
In this case, he will no longer be kind. What he wants to do is to be the most evil person in the world and the most evil person in the three realms.
