"The principle of silver needle drug detection is that it contains sulfide ......"

Zhao Yujiao was suddenly stunned, a term like sulfide is modern chemistry.

Xie Ling'er really frowned, but Zhou Linmo nodded knowingly.

Zhao Yujiao sighed lightly, although Zhou Linmo didn't understand medical skills, he still understood what sulfide meant, and that was enough.

"Silver needles can react with sulfides and turn black. But the poison, that is, Heding Red, contains sulfide, so we can't test other poisons. ”

Zhou Linmo nodded, "Okay, Mrs. Hard." ”

"What are you going to do?"

Zhao Yujiao stood up and hooked the corners of her mouth confidently, as if she had no fear of it.

"Of course, just ask."

"Eh......" Xie Ling'er didn't react for a while, and looked at Zhou Linmo suspiciously.

Zhou Linmo shrugged his shoulders and couldn't help laughing.

"It's worthy of a lady, it's so simple and rude."

Zhao Yujiao chuckled, "It's good to be simple, don't say I'm rude." ”

Zhao Yujiao walked lightly and returned to her seat.

"How, Jiaojiao'er has made some progress."

Qin Tianze saw Zhao Yujiao's smugness, and there must have been some result.

Zhao Yujiao raised her chin and took a sip of wine, because the wine was too strong, she frowned.

You must know that Zhao Yujiao has been observing for a long time, but she didn't expect that something would really happen after she was in a daze for a while.

Now that I finally have the opportunity, of course, I have to take a good inventory.

"No, General, they say, there's a strange maid over there."

"Oh?" When Qin Tianze heard this, he looked around and pointed out, "The veiled one? ”

"Yes." Zhao Yujiao smiled proudly, she didn't expect Qin Tianze to react so quickly.

"What are you going to do?"

"How? Of course, I asked directly. Zhao Yujiao raised her eyebrows and said cautiously, "Look, even if she is really an undercover agent, she is only a bribed." ”

"Oh? How can Jiao Jiaoer tell? ”

"Her pouring posture is very standard, cultivated from the palace."

Zhao Yujiao analyzed, but as soon as she finished speaking, she paused again.

"Yes, Jiaojiao." Qin Tianze knew that Zhao Yujiao had discovered the clue, and chuckled.

"Yes......" Zhao Yujiao suddenly fell silent, she looked at the maid and felt confused again.

Even if that person really came out of the palace, it could be a real killer, a high-quality killer who was cultivated.

That's even more terrifying......

A killer who can endure humiliation, isn't such an existence the most terrifying?

The matter of begonias in the palace has not yet received a reasonable explanation, and now the things in the palace cannot be assured.

Zhao Yujiao was helpless, "Then the general said let's see, what should I do?" ”

"Jiaojiao'er's attention is very good, just ask." Qin Tianze pretended to be innocent and chuckled.

Zhao Yujiao pursed her lips and snorted, "General...... You know, it's strange that this can ask for results. ”

"Jiaojiao'er doesn't go to try it, how do you know?" Qin Tianze looked serious, he looked at Zhao Yujiao with a smile and nodded.

Zhao Yujiao sighed lightly, "Okay." ”

Zhao Yujiao walked out and summoned the maid, accompanied by Qin Tianze.

"General, madam......" The maid bowed her head in resignation, looking timid.

Zhao Yujiao looked at Qin Tianze, Qin Tianze nodded, signaling that Zhao Yujiao could start.

However, such a maid looks even more suspicious.

The more submissive he was, the more Zhao Yujiao felt that there was something wrong with that person.

The same was true of Mo Luhua at the beginning, and now he has revealed his ability and is sharp.

"You ......" Zhao Yujiao looked at her and snorted softly pretending to be cold.

scared the other party into trembling and didn't dare to make a sound.

Qin Tianze held back a smile on the side, seeing what Zhao Yujiao planned to do in order to expose himself to a person who might be undercover.

"Do you know what I'm looking for you?"

Zhao Yujiao asked, staring at the man all the time, and as soon as the man raised his head, he met Zhao Yujiao's eyes, and couldn't help but shrink back.

"Slave, slave doesn't know ......"

"I don't know?" Zhao Yujiao raised her voice and asked rhetorically with pretense of momentum.

The servant girl was so frightened that she knelt down, "The slave doesn't know, the slave doesn't know anything...... I don't know why Madame is looking for me......"

"Then what are you afraid of, it's just looking for you, what are you afraid of."

Zhao Yujiao snorted coldly and looked at her condescendingly, with a lot of momentum.

Qin Tianze snickered on the side, such a Zhao Yujiao, let alone a servant girl, even other people will be afraid, okay.

Zhao Yujiao glared at Qin Tianze and warned him not to laugh, which ruined her atmosphere.

Qin Tianze nodded, coughed very seriously, and pursed his lips.

Zhao Yujiao nodded with satisfaction and continued to ask, "Then, you might as well guess?" ”

"Madame...... The slave really doesn't know...... What did the slave do...... Why did the lady come to confront the slave and maid......"

The maid stumbled, tears falling to the ground.

Zhao Yujiao suddenly relented, I don't know if she guessed wrong, and blamed this maid.

"General?" Zhao Yujiao frowned and asked Qin Tianze's opinion.

Qin Tianze shook his head and motioned for Zhao Yujiao to continue.

Zhao Yujiao hesitated, "But ......"

"There's a problem." Qin Tianze just said this, reminding Zhao Yujiao to continue with confidence.

Zhao Yujiao nodded, helplessly looking at the maid kneeling on the ground.

Qin Tianze said there was a problem? What's the problem? Isn't it just a scared maid......

Zhao Yujiao looked at the maid, "But ......"

"Jiaojiao'er, it's okay."

Zhao Yujiao nodded, she believed in Qin Tianze.

But what's the problem? What's wrong with this maid?

Such a reaction was all within Zhao Yujiao's expectations, and it was very decent......

Slowly, Zhao Yujiao was stunned, and suddenly discovered something.

The more decent, the more problematic it is...... It's more like a fake, very suspicious......

"So, tell me, what have you done? Today. ”

Zhao Yujiao asked her itinerary as if she were examining a prisoner.

The maid looked up and said with teary eyes, "I...... The slave and maid have done nothing today...... It's nothing more than helping to get started, and nothing else......"

"You can tell me where you've been, you don't have to explain anything."

Zhao Yujiao interrupted her and reminded.
