I want the blood of demodragon

A very old green onion?

Was there even a need to guess? She was obviously talking about Lady Onion.

Speaking of which, the last time Song Shuhang ate Lady Onion's sprout, he almost died.

The worst thing was that he ended up dreaming of Lady Onion's life experience for that very reason. After that, he was forced to live for several hundred years as a green onion that kept swaying in the wind. Whenever he recalled that dream, Shuhang felt very aggrieved.

At that time, he was lucky that Daoist Priest Cloudy Mist of the 'Penniless Thief Sect' was nearby and used his 'Emptying Miracle Hands' to take Lady Onion's sprout out of his stomach, transforming it into an onion spirit crystal.

Even now that crystal was still inside his size-reducing purse.

Thereupon, Song Shuhang nodded and said, "I indeed ate a special green onion in the past."

Immortal Fairy Bie Xue said, "No wonder there is such a strong smell of green onion coming from your body."
