Because there was an ample supply of assistive incense, Gu Chengan never had to worry about the lack of fragrance for cultivation, so he never deliberately learned about the types or products of fragrances.
In the past, he had only come into contact with stick incense or smoldering incense, and it was his first time seeing these round, pill-like fragrant pills.
Moreover, when Gu Zhiqi refined fragrances, she was really sloppy.
A handful of medicinal herbs, a pressure cooker, a cup of water; just throw the herbs into the cooker, pour in the water, and light the fire.
He didn't believe she was making elixir; after all, it looked a lot like playing house.
Although the final products were several spherical objects with phoenix patterns on them, he only thought they were medicinal pills, and naturally, they were the type she said could cure insomnia.
He even suspected at one point whether those things scraped from the residue of explosions could end up killing a person if consumed.
