At this moment, Xi Borong only asked about the easy color card in his hand with great interest.

"Nian Nian, sister, how can you tell if this bead is poisonous or not."

When Gu Yunnian went upstairs to get the brocade box, she also took down her small silver box.

When the box was opened, it was the potion that Xi Borong saw last time.

Gu Yunnian took four glass tubes, prepared four potions, and diluted them with water.

Then I took a bead-shaped easy-colored card with tweezers, dipped a cotton swab in a little bit of the liquid in a test tube, and wiped it.

The hazy starlight on the beads suddenly turned pale pink.

Xi Borong asked in surprise: "Is it just this layer of light color on the face that changes color?" What kind of medicine is this? ”

"It's just a change in the color of light, and it's hard to notice if you don't pay attention to it, and it doesn't arouse suspicion. This is a diluted drug, a drug, a psychedelic drug, and it is all pink. ”

Gu Yunnian threw the Yise card into a glass filled with pure water, washed it and picked it up with tweezers, took the clean paper to absorb the water, and put it on the paper towel on the table.

"Fourth Brother Xi, you can try the remaining three potions. The deadly ones are blood-red, the chronic ones are green, and the addictive ones are blue. The darker the color, the greater the concentration and toxicity. ”

Xi Borong suddenly became interested, "I'll try." ”

According to Gu Yunnian's approach, he dipped the remaining three potions one by one and tried them on the Yishi card, and the shallow glow on it all changed color.

Xi Borong was delighted.

When he talks about business and socializes, many people like to settle in those mixed bars and clubs, not that no one secretly places things, but he sees through them.

Occasionally, there are a few hits. Fortunately, it was all the medicine given by some women with crooked thoughts, and he gritted his teeth and endured it, and he couldn't help but find someone else to solve it.

It's just once or twice that he's lucky, and there's no guarantee that no one will ever take another drug.

But he is in business, even if his status is not low, he has to socialize in some business.

What Gu Yunnian gave him was a treasure to him.

It's just that the fluorescent color of this easy-color card is very light, and if you don't look carefully, you can't see it clearly.

"If this is a dark place, you won't be able to see it!" Xi Borong asked, his expression becoming serious.

Gu Yunnian shook his head and explained: "This is the medicine I have concocted, the medicinal properties and concentration are not high, even if you accidentally eat a little bit, it will not have any effect on the human body, and the color change of luminescence is naturally very shallow." If you want to reach the point where it works on the human body, the change will naturally be obvious. ”

As he spoke, Mu Sichen came out of the kitchen with the dishes, and saw that the two of them were both with their heads down and close together.

His tongue pressed against his cheeks, and he felt the urge to lift and throw the person out.

He walked over and said in a deep voice, "It's time to eat, what are you still talking about?" ”

Xi Borong immediately boasted about how amazing and useful Gu Yunnian's reaction was to give him the color change card.

I didn't notice that Mu Sichen looked at him heavily, and said to Gu Yunnian: "Niannian, go wash your hands first." Let's talk about it after eating. ”

"Good!" Gu Yunnian responded obediently and walked towards the bathroom.

Mu Sichen also turned around and went back to the kitchen, so that Xi Borong, who was about to test Mu Sichen and show some magic, suddenly choked and couldn't get up and down.

"Bastard, you can't let me finish before leaving!"

Xi Borong didn't know that what made him more uncomfortable was still to come.
