Lao Wen said with a grimace: "Is this possible? Why do I feel so unreliable? It's just a joke."

I said I didn’t know either, so if it didn’t work, I’d just pull it off.

Then Lao Wen helped me search together. We found a lot of messy things and poured them into the test tube one by one. After pouring each thing, we waited for dozens of seconds to see if there was any change in the color and what kind of compound formula we had in mind.

Sodium acetate solution, sodium bicarbonate solution, Ringer's eye drops, etc.

There are large test tubes and small test tubes used, so try them separately.

After a while, the large test tube changed. Originally, zinc gluconate was light blue, but after I added several potions, it turned yellow.

Lao Wen looked ugly and said it was like urine and smelled like urine.

"Wait a minute, Lao Wen, you have it."

At this moment, I suddenly discovered that a small test tube in Lao Wen's hand was slowly changing, slowly transitioning from light blue to dark blue, and the color was pure, bluer than sea water.

I'm overjoyed. I've seen Blue Potion many times and it looks very similar!

"Which one did you pour just now?" I asked Lao Wen urgently.

Lao Wen stared blankly at the blue potion in his hand.
Chapter completed!
