"Master Su, let me diagnose your pulse!"

Xiao Chen said to Mr. Su.

"it is good."

Grandpa Su nodded.

Xiao Chen stretched out his right hand, clasped old man Su's wrist, and sounded his pulse carefully.

Beside, Su Qing, Su Xiaomeng, Su Zhimin and others all looked at Xiao Chen.

After about five minutes, Xiao Chen let go of Mr. Su's wrist.

"How about it?"

Mr. Su asked weakly.

"Master Su, you are poisoned again."

Xiao Chen looked at Mr. Su and said slowly.

"Poisoned?"

Grandpa Su's eyes widened, a little surprised.

However, he nodded soon: "Yes, I feel that the symptoms this time are the same as last time, and it should be poisoned again."

"What? The old man was poisoned again?"

The faces of Su Zhimin and others changed, and they couldn't believe it.

"That's right, Mr. Su has been poisoned again."

Xiao Chen nodded, stood up slowly, his eyes fell on Su Zhimin.

"Patriarch Su, didn't you say that Mr. Su's diet is in charge of a special person? How do you explain it now?"

"this……"

Su Zhimin's face was ugly.

"The people I chose are all old people from the Su family! I really can't imagine that they will be bribed and poison the old man!"

"Damn it, I'm going to catch them now and cut them into pieces!"

After Su Yan finished speaking angrily, he turned around and was about to arrest people.

"There's no need to look for them, the person who poisoned them may not be them."

Xiao Chen said lightly.

"Not them? Who is that?"

Su Zhimin and the others were taken aback, and looked at Xiao Chen.

"Ok."

Xiao Chen nodded.

"Maybe, it wasn't outsiders who bought them and poisoned Mr. Su."

"That is how the matter?"

Su Yan asked.

"Master Su, do you have anyone you suspect?"

Xiao Chen turned his head and looked at Mr. Su.

Grandpa Su was startled, his eyes swept across the crowd, and he shook his head slowly.

Xiao Chen looked at old man Su, he knew that this old man must have something in his heart, but he couldn't believe it.

After all, the people in the room are all his closest friends!

"Master Su, since you don't have anyone to suspect, leave it to me."

"it is good."

Mr. Su took a deep look at Xiao Chen and nodded.

"In my opinion, the person who poisoned the old man is in this room!"

Xiao Chen turned his head, glanced at everyone, and said loudly.

"what?!"

Hearing Xiao Chen's words, except for Su Qing and Su Xiaomeng, everyone's eyes widened and they were in an uproar.

The poisoner is in this room?

Subconsciously, everyone looked around.

who?

Who is the poisoner? !

"Mr. Xiao, what do you mean? Everyone present is the core of the Su family, so how could they be the poisoners!"

Su Zhimin looked at Xiao Chen, a little angry.

"Well, those present are indeed the core of the Su family, and that's why you will have more opportunities to get in touch with Mr. Su, which is also very convenient for you to poison!"

Xiao Chen nodded and said.

"..."

Hearing this, the faces of the people at the scene changed again.

"Xiao Chen, you fucking fart, who would harm the old man! Tell me, what is your purpose, why are you talking nonsense here!"

Su Yan pointed at Xiao Chen and said angrily.

"Third Su, why are you so excited? Poison, you didn't do it, did you?"

Xiao Chen looked at Su Yan and said lightly.

"Fart, how could I poison the old man, that's my father!"

Su Yan became even more angry, and almost rushed forward to tear Xiao Chen apart.

"That's right, how could my dad poison grandpa!"

Sophie also came over just now, and said angrily.

"That's right. With Su's courage, he probably wouldn't dare to poison."

Xiao Chen nodded.

"..."

Hearing Xiao Chen's words, Su Yan clenched his teeth while heaving a sigh of relief.

But when he saw his father looking at him, he panicked all of a sudden.

"Father, don't listen to Xiao Chen's nonsense, he has no good intentions and wants to make our Su family mess up!"

"Mr. Xiao is right, you don't have the guts to poison."

Grandpa Su looked at his third son and said slowly.

"Yeah, father, you know me best, so how could I poison you."

Su Yan nodded hurriedly.

"Mr. Xiao, I don't want you to talk nonsense. No one present will poison the old man!"

Su Zhimin looked at Xiao Chen and said in a deep voice.

"I'm talking nonsense? Heh, Patriarch Su, I actually have a way to find the poisoner very easily."

Xiao Chen smiled and said.

"any solution?"

Su Zhimin frowned.

"Su Qing, go fetch a basin of water."

Xiao Chen said to Su Qing.

"it is good."

Su Qing nodded, although she didn't know what Xiao Chen was going to do, but at this moment, just follow suit.

Others are also puzzled, why fetch a basin of water?

Su Xiaomeng wanted to ask, but Xiao Chen stopped her with his eyes.

Soon, Su Qing came in with a plate of water.

"give it to me."

Xiao Chen took the water basin and put it on the table next to him.

"Master Su, you are poisoned, I told you last time, right?"

"Well, Manzhushahua, Bianhuahua."

Grandpa Su nodded, he was also curious about what Xiao Chen was going to do.

"Manzhushahua, this substance is a slow poison, colorless and odorless, and even kills people invisible, so that the current medical equipment cannot detect it."

Xiao Chen said loudly.

"However, there is another characteristic of this thing that few people know."

While talking, Xiao Chen took out a pack of medicinal powder from his pocket and poured it into the water basin.

This packet of medicinal powder dissolves quickly in water and has no color.

"This is the medicinal powder I prepared this morning. When it comes into contact with Manjusawa, it will react! The person who poisoned him must have touched Manjusawa, so his hands will turn pale when he puts his hands in the basin. into blue!"

Xiao Chen looked at the crowd and said seriously.

"..."

Everyone was a little dubious when they heard it. Will it change color?

"Brother Chen, the poisoner should wash his hands, right?"

Su Xiaomeng couldn't help asking.

"Well, he can wash his hands, but the poison of manjusawa will enter along the pores carefully, which cannot be washed off! In fact, the old man's body now has the toxin of manjusawa. If you don't believe it, I can cover it up for you now."

As Xiao Chen said, he brought the basin to the bed, then picked up a paper towel and threw it into the basin.

Afterwards, he took out the wet paper towel from the basin and put it in the hands of old man Su.

"Don't worry, old man, the tissue will change color soon, it's a normal reaction."

Xiao Chen said to Mr. Su.

"Ok."

Grandpa Su nodded, looking at the tissue in his hand.

The eyes of the others also fell on the sound of the tissue, watching carefully, for fear of missing something.

Soon, the tissue changed, and at a speed visible to the naked eye, a faint blue color appeared.

"Wow, it really changed color!"

Surprised voices were heard from people such as Sophie and the others at the scene.

"Did you see it? This is the discoloration caused by a small amount of manjusawa, and the poisoner must have more toxins than this!"

Xiao Chen picked up the tissue and looked at Su Zhimin and the others.

"Hmph, who knows what kind of reaction this is, Xiao Chen, what is your intention?"

Su Zhimin stared at Xiao Chen and said.

"This is a pharmacological reaction, and I have no other intentions. I just want to find the person who poisoned it."

Xiao Chen said lightly.

"I think what the third child said is right. You must have other purposes for coming here today! Now, please leave, you are not welcome in the Su family!"

Su Zhimin said coldly.

Xiao Chen didn't speak any more, but looked at Mr. Su.

With Su Qing's support, old man Su sat up slowly.

His cloudy old eyes swept over everyone, and his voice was low: "Everyone, wash your hands in the sink!"

"Father, how can you believe his nonsense, he..."

Su Zhimin's expression changed slightly, and he said.

"My words don't work anymore?"

Old Master Su looked at Su Zhimin and said in a deep voice.

"No, of course it works, I'm just worried..."

"Are you guilty?"

Xiao Chen sneered and interrupted Su Zhimin's words.

"Why am I guilty! Xiao Chen, if none of us change color, you are not allowed to step into Su's house in the future!"

The Su family stared at Xiao Chen and said loudly.

"it is good."

Xiao Chen nodded.

"Now, it's time to start, who will come first?"

"I'll come first!"

Su Qing spoke.

"I also often come to see grandpa, so I am also within the scope of suspicion, I will come first."

"it is good."

Xiao Chen nodded, picked up the water basin, and came to Su Qing.

Su Qing put her hand in, shook it slightly, and then took it out again, without changing the color.

"No problem, next."

Xiao Chen said.

"I'm second."

Su Xiaomeng also stepped forward and tried it, and it was no problem.

"I'm third."

Sophie also came up, without changing color.

Soon, the younger generation in the room had finished trying, and it was time for the Su family brothers.

"I come."

Su Yan stepped forward, glared at Xiao Chen, and then put his hand into the water basin.

"How about it, is it okay?"

"Well, as I said, you don't have the guts to poison."

Xiao Chen nodded.

"you……"

Su Yan almost died of anger, does this mean he is a mouse?

After Su Yan finished the test, the second son of the Su family also went up to try it.

In the end, only Su Zhimin was left.

"Patriarch Su, it's your turn."

Xiao Chen looked at Su Zhimin and said.

"Ok."

Su Zhimin nodded, came to Xiao Chen, and stretched out his hands.

In just a few seconds, Su Zhimin's hands in the water began to show color.

"Changed color!"

Su Xiaomeng, who was standing beside her, exclaimed.

The others also looked over one after another, their eyes widening.

Su Zhimin?

He is the poisoner?

how is this possible!

Everyone couldn't believe it, including Su Qing and Su Xiaomeng.

On the other hand, old man Su on the bed squinted his eyes, and his expression couldn't help but darken.

"No, it's impossible!"

Su Zhimin's expression also changed drastically, and he suddenly pulled his hands out of the water basin.

"How is it impossible? Patriarch Su, look at your hands!"

Xiao Chen looked at Su Zhimin and said coldly.

"This is your conspiracy! How could I be the one who poisoned you!"

Su Zhimin stared at Xiao Chen and said loudly.

"Oh, how is it impossible?"

Xiao Chen sneered.

"The fact is right in front of you, you can't deny it!"
