This is a vast reservoir with a huge area, and there is almost no edge in sight as far as the eye can see.

"With such a huge amount of water, the diluted toxins still pose a deadly threat to the human body, and the origin of this poison is not simple." Su Xuan squatted down, gently picked up a handful of water, and put it in front of him to observe.

Du Renfeng, who was on the side of the "Medical Venerable ......", hurriedly reminded that this water was highly toxic, but Su Xuan just waved his hand, indicating that he didn't have to care.

The water in his hand is very clear, and it looks no different from ordinary water, but this seemingly ordinary water has poisoned tens of thousands of people.

Su Xuan pondered for a moment, a touch of silver flashed over his hand, and a silver needle slowly pierced into the water of the reservoir.

The strangeness happened, and I saw a trace of black gas slowly wafting out of the water, lingering around the silver needle, and it did not disperse for a long time!

In addition, there is a faint foul smell in the air.

"This!" Du Renfeng was stunned, Su Xuan's technique was very similar to the silver needle test poison on TV, but it looked far more subtle than on TV.

Just as he was about to speak, he twitched his nose and frowned: "What smells so bad?" ”

Su Xuan slowly stood up, and there was a cold glint in the depths of his eyes: "I haven't seen this toxin either, it's just that his taste is familiar......

As soon as Du Renfeng heard that Su Xuan had eyebrows, his face immediately showed joy, and before he could speak, Su Xuan walked forward.

"Take me to the steward here."

The staff here obviously all know Du Renfeng, after all, he is the president of the First People's Hospital of Modu, and he has absolute authority in both the medical community and the eyes of the world.

The staff respectfully led Du Renfeng and Su Xuan to a very spacious tent on the side of the reservoir.

Entering the tent, the temperature dropped sharply, and it was surrounded by various professional instruments for research.

At this time, inside the tent, many experts and scholars were anxious, busy studying toxins.

Seeing Su Xuan and the others coming in, a middle-aged man wearing a white robe with a research instrument around his neck stepped forward, and couldn't help but be overjoyed when he saw Du Renfeng.

"Dean Du, are you here to support our research team? Great, with your help, we'll be able to speed up our research dramatically. ”

When Du Renfeng heard this, he shook his head with a wry smile: "Xiao Zhao, I'm afraid I'm going to disappoint you." ”

"This time the reservoir is highly toxic, and I have already collected samples for analysis, but I have come to the conclusion that there is no way to do it."

The middle-aged man known as Xiao Zhao looked gloomy when he heard this, and muttered, "How can this be, if you can't even do it, Dean Du, then wouldn't it be difficult for us to develop this highly toxic antidote......

"Don't be discouraged, I can't help it, it doesn't mean that others can't do it either." Du Renfeng pointed to Su Xuan beside him, and said with a smile, "This is my apprentice Su Xuan, who has been studying abroad in his early years and only came back some time ago, maybe he has a way to poison this time." ”

On the way here, Su Xuan told Du Renfeng not to reveal his identity, and if he wanted to introduce him, he would say that he was his apprentice.

"This is Zhao Shengmin, who studied with me before......" Du Renfeng also introduced Su Xuan.

Only then did Xiao Zhao notice Su Xuan beside Du Renfeng, and his eyes quietly looked at this young man who looked only in his twenties, very young, and not even half his age, and his heart was also full of suspicion.

"Dean Du, it's not that I doubt you, it's just ...... How come I've never heard you say that you still have an apprentice and you're still so young? Zhao Shengmin's eyes were full of doubts when he looked at Su Xuan, and he didn't seem to believe that Su Xuan had any way to deal with this highly toxic incident.

Du Renfeng, who was on the side, was also very helpless when he heard this, and then Su Xuan beside him spoke.

"I want to see the body of the drowned woman." Su Xuan's eyes were calm, he paused, and said, "Using a special instrument to lower the temperature in the room is to facilitate the preservation of the corpse, right?" ”

"The female corpse is still here."

When Zhao Shengmin heard this, his brows furrowed slightly, he was silent for a moment, and said: "You are right, the highly toxic content on that female corpse is more than a hundred times that of the water, for the sake of safety, we did not transport her to the research room, but preserved it with special instruments." ”

"Unless it's our research core, no one else can approach it." Zhao Shengmin looked at Su Xuan and said, "So, I'm sorry, we can't let you visit." ”

The word he used was visiting, and in his heart, he actually subconsciously regarded Su Xuan as a stunned young man with a newborn calf, even if he was Dean Du's apprentice, but he was still too young, how high could the medical skills be for young people at this age?

Su Xuan naturally heard the contempt in Zhao Shengmin's words, but his expression remained unchanged and he was calm and silent.

Du Renfeng's face became serious at this time, and he seemed to be a little angry: "Zhao Shengmin, are you a good person, when you followed me, didn't you follow my ass and beg me to teach you medical skills?" Now you've put me up a fight, haven't you? ”

When Zhao Shengmin heard this, his expression was a little panicked, he immediately looked around, and only breathed a sigh of relief when he found that no one had noticed the situation here.

With a smile on his face, he quickly lowered his head and lowered his voice: "Dean Du, where are you talking about, you are my mentor, how can I dare to put up a fight with you." ”

Then Zhao Shengmin still glanced at Su Xuan suspiciously, his face changed, as if he was considering something, and finally gritted his teeth: "Okay, I'll take you to see the corpse, but you must not touch ......"

Then Zhao Shengmin took Su Xuan and the others to another tent, where the temperature was very low, almost close to freezing.

There were various instruments all around, but in the center of the tent was a glass cover made of special materials, and in it, a female corpse lay impressively.

"It's her, when we first found her, according to the identification, the time of death had been more than twenty-four hours, and after so many days, the police did not find any information about this body at all."

Zhao Shengmin sighed: "This corpse seems to have appeared out of thin air. ”

And just as his words fell, Su Xuan also saw the whole picture of this female corpse through the glass cover, and the next moment his pupils shrank slightly, and his face couldn't help but show surprise.

Because, this dead man lying in a glass cover, he has seen.

"Wang Ling'er!"

The female corpse in front of her is the daughter of the Wang family, Wang Ling'er!

When Wang Jiajia led people to surround the Lin family, claiming that Yu Yang raped Wang Ling'er and made him hang himself, Su Xuan saw Wang Ling'er's body.

"It's just that Wang Ling'er died some time ago, how could she appear in this place?"

"And, he's also poisonous......"

"Can a dead person be poisoned?" Su Xuan's eyes froze, and a guess appeared in his heart, Rao couldn't help but feel a chill in his heart with his calmness, "Or is it that someone will use the corpse of the deceased to do experiments again?" ”

"There's something strange about this." Su Xuan recalled the scene when Wang Jiajia led people to surround the Lin family, and she believed that Wang Linger was humiliated because she was raped by Yu Yang, and finally hanged herself.

But the truth is not like this at all, because Yu Yang has no function in that regard at all, that is to say, it is impossible for him to rape Wang Ling'er, and Wang Ling'er was killed by others.

The person behind him wanted to divert his attention, so he blamed Yu Yang.

"Wang family, what are you going to do this time......" Su Xuan's eyes gradually penetrated Sen Han.

"Su Xuan, how's it going? But what is the conclusion? Du Renfeng on the side saw Su Xuan fall into deep thought, and waited for a long time before cautiously asking.

"Well, there's so much involved in this matter, and I'll need some time to prove my speculation." Su Xuan nodded, and did not tell Du Renfeng and the others about Wang Ling'er's identity, because even if he told them, it would be useless, and he might even startle the snake.

"Hehe, you kid is not small, we have so many top experts and scholars in the Demon City here, they have gathered here to study together for so long, and there is no progress, you tell me now, you just came over to take a look, and you have a clue?"

Zhao Shengmin couldn't help but laugh when he heard this, Su Xuan's words were tantamount to saying that none of their so-called top experts were as good as him, a hairy boy in his twenties.
