"When only the last one was left, I noticed a book next to it. It described how to cultivate various poisonous insects... I learned the name of the flying fish worm from the book, and I was just trying to sell it today... I didn't expect it to be so valuable. I regret it so much..."

Lan Zhi began to admire her ability to make up lies. As for why she was unwilling to continue selling the Flying Fish Gu, the reason was very simple. The middle-aged man was willing to pay such a high price, which showed that they were very precious.

Lan Zhi is not short of spirit stones now. She only has a Ruyi Ding, so why should she sell all the fish?

My brothers don’t need so many spirit stones for cultivation.

Maybe after leaving the Kingdom of Da Rui, I can sell this poisonous insect for a higher price.

In addition, the "Poison Spirit Sutra" only records the toxicity of the flying fish Gu, and also mentions that "the Gu worm can be used as a medicinal material for alchemy after death."

It didn't specify what kind of pill it was.

Because this book focuses on the "poison" section and introduces the methods of refining various poison pills, none of these poison pills require the Flying Fish Gu. Similarly, there are no such pill recipes in "Medical Theory".

Lan Zhi couldn't figure out what the light pink pill that the middle-aged man had just refined was, but there was no doubt that the flying fish Gu was an indispensable ingredient in it. There were already enough flying fish Gu in the belly of a fish, but the middle-aged man said, "No matter how many flying fish Gu there are, I will take them all." This indirectly reflects that the light pink pill can definitely be sold at a very considerable price, so he has the confidence to take the Gu.

However, the elixir formula has always been precious, and Lan Zhi has already obtained the alchemy furnace she wanted. Both parties have obtained what they need, so there is no need to continue the transaction.
