Chapter 349: Poisonous **** 5

Shopkeeper Liu cross-examined the guys and found no abnormalities, so he had to look for Gu Changsheng with a bitter face: "Three young masters, I haven't found out, and they don't recognize anyone."
"Their family background is detailed. Have you checked who they have been with recently?" Gu Changsheng asked.
"Checked it. I can't help it, should I ask Master Li Zheng to go to Panguan?"
"Such a trivial matter." Gu Changsheng frowned and turned back to the restaurant, "I'll check it myself!"
...
The guys in the restaurant are all recruited from the town, knowing the roots.
Gu Changsheng observed all the more than a dozen fellows, and found no abnormalities.
Judging the case... he is not good at it. President Ba only needs to give orders, and someone will give the results.
But today, he has to do it himself. Fortunately, there is a polygraph in his space.
Gu Changsheng turned his back, took out the polygraph, and put it on the table. This is a battery version of the polygraph, and the light turns on when the switch is pressed.
Everyone looked curiously.
"Liu Si, come here." Gu Changsheng called.
Liu Si stepped forward, composing respectfully: "Three Young Masters."
Gu Changsheng put Liu Si's finger on the card slot of the polygraph. After the machine read the tester's heart rate and pulse data, he asked, "Have you given all the remuneration this month to your wife?"
Liu Si was very strange: "Three young masters, why do you ask this?"
"Just answer it," Gu Changsheng said.
"Handed in." Liu Si's eyes flickered.
The indicator light on the tester turned on, and he smiled: "Liu Si, you lied. Did you pay all the money at home."
Liu Sida was shocked: "Master, how do you know?"
"Have you seen these lights? When they light up, you have lied. The more lights are on, the higher the degree of lying." Gu Changsheng asked again, "Did you scold the shopkeeper Liu today?"
"No!" Liu Simeng shook his head.
The polygraph turned on again, and the shopkeeper Liu stared at Liu Si angrily. Liu Si forced his head down: "Shopkeeper Liu, I was wrong. I just complained that you doubted me. I really didn't mean anything else."
Gu Changsheng smiled softly and glanced over the other guys: "Now, let's test one by one. I know that the person who prescribed the medicine is among you!"
The guys looked at the polygraph in amazement: "Three young masters, you still have such a magical thing, like a god, that can see through people's minds."
"Yes, now I admit the mistake, I can still open the Internet. When the polygraph is detected, I have to send off the official." Gu Changsheng said.
"I haven't given the medicine, I'll try it." The guys are happy to test, and line up one by one to prove themselves.
More than a dozen guys, the last one was measured in a short while.
The man's face was gray, his hands and feet trembling and he dared not move forward.
Everyone knows that there is a ghost from his reaction. Gu Changsheng yelled, "Wang Er, don't you tell me?"
"Three young masters!" Wang Er weakened his legs and knelt down. "Three young masters, please forgive me! I will never dare anymore!"
"Sure enough, you were poisoned!" Gu Changsheng sneered, and the others were angry.
"Wang Er, are you crazy? You even poisoned it in a pan."
"The Third Young Master is so good to us, you have been a black hand, you are too human!"
"..."
Wang Er knelt on the ground, trembling: "I blamed me for being obsessed with my heart for a while. The man said that Croton would only cause diarrhea, and then Miss Xia would not be able to set up a stall. I didn't expect that it would be a burden to the Third Young Master!"
"Who is that person?" Gu Changsheng asked.
"That person..." Wang Er hesitated.
