Song Yan was not annoyed either, so he brought a clean handkerchief and wiped it for Qi Ruan.

But Qi Ruan didn't appreciate it and raised her hand to swing it away for Song Yan.

Song Yan pretended to be angry and glared at Qi Ruan: "I won't give you candy if you don't obey!"

"Bad guy!"

Qi Ruan resisted.

"I don't even give me candy."

"..." Qi Ruan looked aggrieved, but obediently took her hand back and held the water cup obediently, as if the threat was very useful to her.

After taking care of her body for so long, Song Yan had already touched her mother clearly. Her habits and personality were clearly visible to Song Yan. Song Yan could easily make Qi Ruan obedient.

Next, Qi Ruan cooperated more.

Maybe it was because of anger Song Yan's threat. Qi Ruan would sometimes make trouble on purpose. She ate half of the lunch brought by the nurse and then pushed it out with the tip of her tongue like a child. Song Yan didn't get angry with her this time, but patiently coaxed her.

Soon, Qi Ruan stopped getting angry.

Especially after lunch obediently, Song Yan sent someone a small piece of fruit candy, and Qi Ruan even followed Song Yanyan's plan.

After taking the medicine, Qi Ruan fell asleep again.

Song Yan left quietly, and came to the outside room, slumped on the sofa, so tired that he couldn't open his eyes, but he didn't dare to sleep.

Now they had not had time to find a suitable nurse. If she fell asleep and no one was taking care of her, she might have an accident again.

Fortunately, Lu Yi came back not long after.

Looking at Lu Yifengchen's exhausted look, Song Yan hurriedly came forward: "How is it? Have you found out what you found?"

"I found out that the saline injection from 11:00 to 3:00 am last night had drugs similar to drugs. The effect was similar to drugs. In addition, the patient was emotionally unstable and external stimulants, so he became ill."

Lu Yi collected all the potion bottles that Qi Ruan had used and tested the residue inside, and it turned out that there were really stimulant analogs.

This answer was expected, and Song Yan was not only angry but also confused.

"We were still here last night, how dare that person take action?"

Song Yan was puzzled.

They originally suspected that the other party might have been tricked after they left, but they didn't expect that they had been successful when they were still there.

"I didn't expect this to be the case."

Lu Yi was a little upset.

"But I should have guessed that the patient is weak and can't bear the injection of a large amount of stimulants at one time, so they chose to continue injecting small doses. When the patient wakes up during the day, the disease just happens to occur."

It can be said that the other party calculated the time very accurately.

They accurately judged the time when Qi Ruan woke up, then calculated the appropriate dosage, and prepared for their arrival.

So when Song Yan approached, Qi Ruan completely lost her mind and bit Song Yan.

All of this was planned artificially.

And those who can think of this method have to be said to be deeply thoughtful.

"What is this person's purpose?"

Song Yan was very angry.

“Is it just to get my mother to bite me?

What are the benefits for him?

Or is this a warning, and the next one is the main meal.”

“It’s not impossible.”

Lu Yi's face was serious.

"I don't think the other party will give up so easily. Let's be more careful next."

This time it is a stimulant, next time it is a poison?

"Can you find out who did it?"

Song Yan remembered the most critical point.

"Have you ever contacted suspicious people during the transportation of this drug?"

They noticed that they were one of them, and the most fundamental thing was to find the mastermind behind it.

Otherwise, they will always be scared.

Song Yan would not think that the other party was having fun with her. This was likely to be a provocation and a horn for the war.

"Basically 80% of patients use saline, and it is not a special drug, so no one will take care of it, but it is absolutely impossible for people to easily deal with it. This medicine is monitored from the time it is out of the warehouse to the labeling of the patient's injection. I went to check it, but there was no clue."

Lu Yi had long thought of this problem.

He checked all the surveillance in various hidden corners, but there was no suspiciousness.

Lu Yi even suspected that someone might have mixed in wearing the nurse's clothes, so he called the responsible staff and asked him to take three people to carefully identify them, confirming that all the nurses wearing masks were their own people.

The use of medicines is a big deal, and it is impossible for ordinary people to easily access them.

Not to mention tampering with it.

The clues were interrupted, and Lu Yi was also worried.

"Do you think it's possible that one of the three nurses was wiggling?"

Song Yan guessed.

"Since it's difficult to start during the process, and I can't be sure if it's given my mother's medicine, the man simply bought the nurse and asked the nurse to do it directly during the injection."

This is the easiest and least prone to making mistakes.

But Lu Yi vetoed this possibility without hesitation: "It is absolutely impossible that these three people did it. They were in the intensive care unit before and temporarily transferred them to the hospital yesterday. No one knew the news. How could that person bribe them in advance?

What's more, the three of them are in and out together, and it's too difficult to buy the three together."

The first is that time does not allow, and the second is that once one of them is revealed, the other party will be exposed.

This is too risky.

"Let's check it out. We can't guess how to operate it. It doesn't mean that the other party is prepared and doesn't know how to operate it."

Song Yan was on the safe side and decided to investigate together.

"But don't reveal the news first, let's check it yourself."

Song Yan was worried that the other party would take action again.

Lu Yizheng had this idea: "Yes, I will continue to collect information."

After saying that, Lu Yi remembered another very important content: "I said before that the Qi sisters were not masterminds, but now I can definitely not be separated from them, because their stimulation also plays a great role in the patient. Their appearance is similar to the fuse, so these two people are also part of the plan, and they may be able to start from them."

Lu Yi never thought these two sisters were innocent.

After all, they hated Qi Ruan so much, how could they be kind to come to see her?

Besides, no one knew about Qi Ruan's hospitalization, where did they get it?

The reason why Lu Yi didn't let Song Yan cause trouble for them at the beginning was that he wanted to first find out what medicine Qi Ruan had applied, and then determine what role the two sisters of the Qi family played in it.

Now he knew that it was her business that Song Yan wanted to do.

"You mean, these two people are involved?"

Song Yan repeatedly confirmed.

"The reason they came here is to stimulate their mother and make her mood reach its peak."
