Gu Lili explained, "I just helped him out, and of course, he helped me too."
"What did he help you with?"
Gu Lili had promised Su Changzhi that she could not tell anyone about his coffin cave in Wangchuan Mountain and the Poison-proof matter, but she had asked him privately in the past few days since the pills she was making were for Long Yubei to take, and if she didn't explain it to him clearly, he definitely wouldn't take them.
Su Changzhi agreed that she could tell Long Yubei some things that were permissible.
"I asked Qing Li to find a few types of herbal ingredients, and I needed his help to process them into pills. Nobody else could complete it even with the same materials, and this product will be very useful for me, you'll see."
Long Yubei still remembered the deadly poison she mentioned during their last walk by the lake, so he didn't ask further, although that was just a joke made by Gu Lili, which he took seriously.
