"Good guy, there is a situation. Someone is really eyeing this pool?"

"No way. During the day, the hostess repeatedly jumped into the pool and snorkeled to take pictures, but she never found any treasure hidden in the pool!"

"Could it be placed on the grass around the pool?"

These people who were following them whispered, not worried about being heard by the two people who climbed over the wall.

Because they are far apart.

Fang Gaojie stared seriously. If there was anything strange about these two people, he decided to arrest them himself!

In the night vision device, only two figures, obviously a man and a woman, were seen. After climbing over the wall with difficulty, they stood there for a while and then slowly approached the swimming pool.

They all carried backpacks, and when they came to the pool, they looked left and right to see if anyone was around.

After watching for a while, the man made the first decision, opened his backpack, took out buckets of canned boxes, and poured the contents of the boxes into the swimming pool.

The woman didn't move for a while. After the men poured down three cans, she opened her backpack, took out the cans, and poured the contents into the swimming pool.

The group of people watching all heard the conversation between the two people in their earphones.

Luo Huixin said hesitantly: "Just put this much. It is poisonous. If you put too much, it will kill people."

He Duan seemed cooler and his voice was calm.

"Let us put away everything we brought. We just let her stay in a hospital. We try to make her disappear for a while. It won't kill her."

Luo Huixin glanced at He Duan cautiously: "But I checked online. As long as the concentration of this stuff is high, you can easily be poisoned and die if you drink even a little bit. This swimming pool is not big, and we have put enough in it before. Otherwise,

still--"

She choked on her words and could not continue because He Duan turned his head and stared at her with his sinister eyes.

"Are you questioning my dosage, or are you questioning my decision?"

Luo Huixin's heart tightened, feeling that He Duan was a little strange at this moment.

She was unhappy with He Huanxi, but that didn't mean she wanted to... harm people, kill them!

She swallowed quietly and quickly shook her head: "No, no, I will listen to you."

The two men moved very quickly, and within ten minutes, they threw everything they brought into the water.

Immediately afterwards, the two people quietly left the swimming pool and went out the same way they came in.

The person who was secretly watching quietly stared at the spot for another half an hour, and another soft sound of footsteps came from the earphones.

The man said: "Let's go, no one is squatting here."

The woman muttered: "No one is watching in the first place. Who would be watching people in the middle of the night? There is no surveillance here."

The tracking team stayed in place for another half hour.

After confirming that the two people were really gone, they came to the swimming pool and turned on the headlights around the swimming pool.

Fang Gaojie first sent someone to adjust the surveillance cameras they had placed around them to identify the photos of the two suspects.

Then he squatted down and looked carefully at the water in the pool.

On the surface, the swimming pool appears unchanged and does not emit any odor.

Some people were about to pick up a squirt of water, but were immediately stopped by Fang Gaojie, "Don't touch it! This water must be poisoned!"

He looked at another member: "Go get the test paper and try it out, see if you can detect anything."

Before the test paper was brought over, someone noticed something was wrong.

"Do you think the water in this swimming pool is bluer?

Others subconsciously said: "Shouldn't the water in swimming pools be blue?"

An idea flashed in Fang Gaojie's mind, "I understand, it's copper, copper sulfate!"

The water in the swimming pool is naturally not blue, but colorless.

The reason why it is usually blue is because the swimming pool reflects the sky, and the sky is blue!

But it's dark now, and the water in this swimming pool still has a blue tint. Apparently, the copper content in it is very high, which causes the water solution to appear blue.

If it is really copper sulfate, then it will be easier to judge using reagents——

It is acidic and easily soluble in water, but after it loses crystal water after being left for a long time, white powder will precipitate.

They collected some solutions and took them to a professional institution for testing overnight. After Fang Gaojie did this, he called Xiao Zichen.

It's not a pleasant feeling to be woken up late at night, let alone someone like Xiao Zichen.

As soon as I woke up, I heard a frightening news.

He was so frightened that his soul almost flew away, and he woke up immediately.

"What are you talking about, someone poisoned the swimming pool with copper sulfate?!"

Fang Gaojie said in a deep voice: "I'm not sure if it's copper sulfate. The current preliminary judgment is that it's probably that the relevant solution has been sent to a testing agency for testing. I only know that toxic substances should have been added."

Xiao Zichen couldn't remember what copper sulfate was for a while. While listening to Fang Gaojie's analysis, he searched online to find out what it was.

——The copper ions in copper sulfate are heavy metals, which can denature proteins and are difficult to degrade. After entering the human body, they can cause heavy metal poisoning.

If the concentration of copper ions in the water is too high, many organisms will not be able to survive, not even humans!

Xiao Zichen's eyes widened. Isn't this a different kind of pesticide poisoning?

Further reading, it turns out that when copper sulfate is mixed with lime water, Bordeaux liquid can be produced, which can be used as an agricultural fungicide.

But once used in excess, many fish will be killed!

Xiao Zichen took a breath of air.

He had seen the photo sent by Fang Gaojie. The water in the swimming pool had turned blue, and the concentration must have exceeded the standard.

Once it's daytime, the pool water reflects the blue of the sky, perfectly hiding this blue color. Plus, it's colorless and odorless, so it's hard not to be fooled!

One sip will kill you!

If He Huanxi wants to go diving to shoot a video, he will definitely not be able to avoid contact with water.

Xiao Zichen no longer hesitated, sent photos to Xiao Jue, and made a phone call to explain the situation.

Xiao Jue has been meditating and resting these past few days instead of lying down to sleep.

The Ghost Festival is approaching, and he needs to adjust himself to the best state.

Late at night, the ringtone of his mobile phone broke his state of unity indoors and seemed extremely harsh.

Xiao Jue was thoughtful, stood up unhurriedly, and picked up the phone.

As soon as the call was connected, Xiao Zichen immediately said: "Did He Huanxi offend someone? Why would someone want to kill her?"

"Didn't you ask me to keep an eye on her? Once she enters the shooting state, there are more than a dozen people watching her, so there is no need to worry. So I kept an eye on the swimming pool where she was going to shoot, but tonight someone actually went there and poisoned her!"

"Fang Gaojie said they are a man and a woman, about thirty or forty years old. It should not be vicious competition among peers."

Thirty or forty years old?

Xiao Jue's eyes flashed slightly, and the figures of two people flashed in his mind.

Xiao Zichen asked again: "What are you going to do?"

Xiao Jue came back to his senses and said calmly: "Tell He Huanxi, she will decide this matter."

Xiao Zichen waited for a while, but no other news came, so he couldn't help but ask: "That's it?"

He said anxiously: "We should call the police. Poisoning and harming people is not a trivial matter. We cannot let bad people get away with it!"

Xiao Jue's voice was as cold as ice: "Zichen, this is He Huanxi's matter. We should let her decide and respect her decision."

Xiao Jue softened his tone and said, "I believe she will handle all this."

Xiao Zichen originally wanted to say something, but was choked by this sentence and couldn't say anything.

After a while, he held back two words: "Okay."

Just as he was about to hang up the phone, Xiao Jue's voice came again: "Don't call her now. She's resting. She's very tired from shooting every day. Just tell her early tomorrow morning."

Xiao Zichen:......

Fine.

The next day, when He Huanxi came together, she received a message from Xiao Zichen late at night, saying that there was an urgent notice to tell her and asking her to send him a 1 when she woke up.

He Huanxi raised his eyebrows. Could it be that the rules for live streaming have changed for the second time?

She first sent a "1" and then checked the blocked program group announcement group. She couldn't find any rule changes, so she went to wash up first.

After taking care of her appearance, He Huanxi picked up her phone again and found that Xiao Zichen had called her five times.

He Huanxi frowned slightly, are you so anxious?

She called back.

The call was picked up quickly, and Xiao Zichen got straight to the point: "I'm going to tell you a very important news. Listen to me, be calm and don't be impulsive. Last night I found two people climbing over the wall at the swimming pool.
