As for why the Mirage spirit bug was not simple, it was because it was not a bug, but a spirit beast.
"The Mirage spirit bug is a rare species of spirit beasts. It is good at attacking with consciousness and can cause people to hallucinate. It is also extremely fast and is a rare natural enemy. Fortunately, its defense is pitifully weak. As long as you have a little cultivation Foundation, you can easily kill it. Therefore, it is usually hidden in remote places and rarely appears in the world." Said Ling Chuxi as she looked carefully at the Mirage spirit worm in the Jade bottle. She had read about The Phantom spirit bug in the 'all spirits record', so she could tell its origin at a glance.
