When he woke up, the social animal Yu Jianqing transformed into the cannon fodder at the bottom of the world of immortality - a butterfly demon. Good news: The species is a rare phantom glazed butterfly with dazzling wings and a beautiful appearance. Bad news: The combat effectiveness is about zero. It is a top-notch item for monks to refine elixirs, demons to quench their greed, and monsters to fill their teeth. In order to keep these beautiful wings, Yu Yingying decided to take the "Gou" way to the extreme. She painstakingly studied the butterfly tribe's natural illusion skills and disguised herself as a flower in the mountains, a stone on the roadside, and an ordinary butterfly background behind the boss. As long as she doesn't move, no one can spot her! However, things began to go wrong. She witnessed Qing Leng Jian Xian being trapped by his inner demons, and couldn't bear it. She secretly used illusions to create a beautiful dream for him that would last for three lifetimes. After waking up, the sword immortal said to everyone he met: "I have a Taoist companion in my dream who loves me deeply." Yu Qianqing:? I'm not, I didn't, don't talk nonsense! She watched the demon as he was dying from his injuries, and she used illusion magic to create an "ancient restriction" to cover him to prevent him from being dismembered by his enemies. After recovering from his injuries, the Demon Lord searched the world: "Which peerless master set up this array to save me? I am willing to pledge myself to you!"
