People in Jiangsu or Zhejiang wasn't very fond of roasted brains since they were into mild flavor, like a young girl singing about romance beating with red sandalwood clappers. But roasted brains were really popular in Sichuan province as Sichuan food was much rougher on the taste, more like strong tough guys roaring about the mighty waves with iron clappers.
Some porcine brain stirred and mixed with seasoning like mashed garlic and coriander would become a perfect dish in a Sichuan BBQ joint.
However...
... This brain in front of Su Bai was much larger, because it was not porcine but human brain.
And it wasn't cooked.
And it wasn't served with at least some mashed garlic.
And it had been kept in a culture dish for decades, probably had exceeded its edible time limit a long time ago.
And there were probably a lot of chemical substances in that culture dish that was much more harmful than preservatives.
But Su Bai was still drooling because he felt so hungry.
