There are many people who buy glycolic acid in the city, and it is difficult to find good things. Yu Jiu can't find glycolic acid, and his heart is worried.

One day, he heard that there are wizards in the west of the city, specializing in all kinds of strange goods. Then he went, saw the master, and asked respectfully: "I dare to ask if you have glycolic acid anywhere?" The master of the house raised his eyes, looked up and down, and said, "Of course, why do you need it?" Yu Xi said, "If you want to buy it, you can use it for other purposes." The master of the house nodded, led Yu Yu to a corner, took out an urn, and said, "This is a good glycolic acid, the quality is excellent, and it is difficult to find elsewhere."

The rest of the view, the color I asked the price carefully, and the owner reported the number, and felt that it was a little expensive. I negotiated the price with him, and my words were sincere. The owner was unmoved at first, but Yu Chen took advantage of the harm, and he said that he would buy more often. The owner thought about it for a long time, and finally lowered the price.

Yu then paid the gold and bought glycolic acid and returned. On the way, I was happy, thinking that I finally got what I wanted, which can relieve my urgency, it is really a blessing. When I return home, hide it properly for later use.
