Usually the most important source of infection is the first person to become ill.

Someone is investigating what's happening outside, and no one will be able to enter the treatment center in the short term. There's even a circle of people guarding the area to prevent any accidents.

Yi Ning was also somewhat affected by the patient, and his thoughts were a little confused.

That's why I didn't think of checking the first patient for a while.

Yi Ning went to check on the people. Yu Youyou drank the warm water in her hand and walked to the people lying on the ground to see their condition.

She reached out and touched the person's forehead, moved his head to see his expression, and then looked at the next one.

Yi Ning noticed her movements, but seeing that she was not feeling unwell, he let her go.

Yu Youyou's observation plan was thwarted by someone.

This is the person who contacted Yi Ning.

He probably had a good physique. Everyone was still asleep, but he was the only one who woke up when Yu Youyou touched him. He grabbed Yu Youyou's wrist, and his eyes were not focused yet, but his face showed a ferocious expression.

Yu Youyou: “…”

She said, "Can you let go?"

Not only did the young man not let go, but he subconsciously clenched his fingers, and then he heard a soft cry of pain.

His empty consciousness gradually became clear. He saw Yu Youyou's aggrieved and tearful look, and realized that he had held Yu Youyou's hand too tightly.

He subconsciously loosened his grip. Yu Youyou looked at the red mark on her wrist and felt even more aggrieved: "What's wrong with you?"

"Yes...I'm sorry." Seeing the circle of red marks, the young man thought that this girl was too soft.

I couldn't help but think of the touch in my hand just now.

The skin is delicate, as if boneless.

So girls’ hands...are like this?

A blush crept up his ears, and the young man apologized decisively again: "I'm sorry, it's my fault."

"Since you've apologized, that's all." Yu Youyou pursed her lips and muttered softly, "I know, you guys might be quite vigilant. I didn't expect you to wake up."

Without waiting for the young man to speak, Yu Youyou asked, "I want to examine you. Do you want to lie here or on the bed?"

"Examine me here first." The young man lay down.

Yu Youyou rubbed her wrist and saw that the red mark had faded a little. Then she raised her hand and poked the young man's forehead, and at the same time instructed the young man to turn his head.

I thought he was using an instrument to check the young man: "..."

Feeling the exceptionally soft fingertips on his forehead, not only the young man's ears, but also his neck and face were stained a little red.

Yu Youyou didn't notice this. After she finished her inspection, she stood up and said, "Okay, I'll go check on the others."

"Thank you." The young man felt the girl's hair brushing against his arm, causing a tingling sensation.

When Yu Youyou went to examine another person, he couldn't help but watch Yu Youyou's fingers fall on other people's foreheads.

...It's actually quite good to use instruments to check, there's no need to touch every person like this.

Realizing his thoughts, the young man's face turned red.

He coughed lightly to suppress his restlessness.

"What's wrong?" Yi Ning turned around and looked at her carefully. "Are you feeling unwell?"

"It's okay." The young man avoided Yi Ning's gaze by getting up. He asked, "What's going on? How come our mental power is also going berserk?"

"If you're okay, come and help me." Yi Ning wasn't paying attention to him, and didn't notice anything wrong with him. "The situation is quite complicated. I'll tell you after I finish checking it."

The young man silently got up and helped.

Yu Youyou finished checking the people on the ground and finally checked the burly young man on the bed. Seeing her reach out and poke his forehead, the young man couldn't help but ask, "Can't we use an instrument?"

"I'm not familiar with the operation of the instrument." Yu Youyou explained, and then turned her attention to Yi Ning. "Sister Ning, did you see anything?"

"I haven't seen any other symptoms yet, but his condition is deteriorating faster than others. And they seem to have affected me a little. I may need to rest first." Yi Ning was helpless.

Yu Youyou opened her eyes wide: "Then you go and rest first, I'll be here guarding, it's okay for me."

"Aren't you feeling uncomfortable?" The young man couldn't help but look at Yu Youyou.

Yu Youyou shook his head.

Yi Ning sent out some messages, and then went upstairs to rest.

But she didn't leave Yu Youyou downstairs. She put a warning bracelet on everyone who stayed on the first floor.

As for the young man who Yi Ning had called for help before?

Throw away the JPG after use.

Those who have some problems can only stay down there. If they really go up there, won’t it affect Yi Ning?

Yu Youyou entered Yi Ning's room.

Unlike Yu Youyou's room, Yining's room is simpler and more elegant, with black, white and gray as the main colors.

Taking Yu Youyou to sit down, Yi Ning first gave Yu Youyou a few Yuanyuan fruits - this was Yi Ning's excuse to let Yu Youyou into her room.

But when Yu Youyou really came in, Yi Ning didn't know how to start.

However, after Yu Youyou finished eating half of the Yuan Yuan Fruit, she looked at Yi Ning with a smile: "Sister Ning, do you have any questions for me? You can ask me. At least I won't lie to you. If I encounter a question I don't want to answer, I will tell you directly."

"I don't doubt that you will lie to me." Yi Ning rubbed her head, "What are you thinking about all day long?"

Yu Youyou looked innocent.

But it must be said that Yu Youyou's words dispelled Yi Ning's concerns to a certain extent.

Since Yu Youyou hadn't been unwilling, she also tentatively asked, "Did you let that group of people come over on purpose?"

"Yeah." Yu Youyou was pretending when she was downstairs, but when Yi Ning was the only one upstairs, Yu Youyou became calm.

"I'm just saying..." Yi Ning murmured, "So you noticed something was wrong from the beginning?"

Yu Youyou took a bite of the Yuan Yuan Fruit and said, "Actually, I'm just more sensitive to mental power, so I thought I'd call everyone over to show you. But before you could even see them, they were all like this."

"I even specifically said that I was afraid you would say I didn't cure the patient, so they were willing to come with me."

Yi Ning: “…”

The previous weirdness is now understood.

But there are still more puzzles that cannot be solved: "So what else did you find?"

"Hmm..." Yu Youyou blinked, "Someone did this on purpose. I know who it was. Do you want to know?"

Yi Ning almost said that she wanted to know, but she then suppressed her impulse. She didn't want to be influenced by Yu Youyou at this time.

"I don't want to know for now. Can you tell me when I ask you?"

"Sure." Yu Youyou agreed readily.

Yi Ning really needed to rest, and after she relaxed, she fell asleep on the sofa.

Yu Youyou was still chewing the Yuanyuan fruit, but after she finished eating it, she hummed softly.

There are no lyrics and it's not a fixed tune, she just hums it for fun.

But Yi Ning's frown relaxed, and her tense mental strength gradually relaxed.

——

Yi Ning only slept for an hour.

She woke up on time an hour later and found that she had recovered unexpectedly well.

She didn't rush downstairs, but opened her computer and checked her inbox.

Sure enough, there is already a message.

She opened it and took a look, her expression becoming more subtle.

This expression made Yu Youyou curious: "What's wrong?"

"After they finished their investigation, they discovered that the movements of the dozen or so people downstairs had very little overlap. They then checked everyone in the base and compiled a list of suspects."

Yu Youyou felt that there was nothing wrong with these. She couldn't understand why Yi Ning had such a strange expression.

Until Yi Ning said: "The biggest suspect is you."

Yu Youyou: “?”

She was stunned for a moment.

"I've taken a look, and this is mainly because your identity has not been confirmed." Yi Ning shook his head, "There's nothing we can do about it. It will take some time to check your identity, but you don't have to worry too much. I'm just suspicious."

Yu Youyou was not angry as Yi Ning thought. Instead, she was still smiling: "I know, and I know Sister Ning will help me, right?"

"That's great," Yi Ning showed the list to Yu Youyou. "In fact, even if it's you, your suspicion is very low in comparison. We haven't really found anyone worthy of suspicion yet."

Yu Youyou was indeed the first one on the list, and she didn't know the rest of the people.

And she is 19 percent suspected.

"Any suspicion below 20% is very low. In fact, we haven't found more this time." Yi Ning explained, "After all, it happened too suddenly."

Yu Youyou understood what she meant and said sincerely, "I think your army is great!"

At least they won't put all the suspicion on her just because she seems to have no background and a questionable origin.

Yi Ning took the opportunity to ask: "Do you want to stay?"

If they could keep Yu Youyou, she would be the healer of their legion.

With her help, there was no problem in keeping Yi Ning in her base.

Leaving behind a high-level healer who can perform group treatment will only benefit the legion and not harm it.

And her intuition told her that Yu Youyou's potential was more than that.

Yu Youyou declined Yi Ning's invitation: "I want to go to the main planet first."

"Okay." Yi Ning was helpless, but emphasized, "If you want to join the legion, please be sure to consider my invitation first."

Yu Youyou's eyebrows curved: "Okay!"

Yi Ning was satisfied.

"Do you want to rest more? I'm going to go downstairs to take a look." Yi Ning asked.

Yu Youyou shook her head: "I'll go down with you."

The list that Yi Ning showed Yu Youyou only had names on it, and Yu Youyou had just arrived at the base. She didn't know that two-thirds of the people on the list were the ones lying on the first floor of the treatment center.

In a sense, the person who took action is most likely among these dozen people.

As for why he followed Yu Youyou even though he knew there was something wrong with him?

In that situation, everyone agreed, so how could he refuse?

Even those who were supposed to be on patrol quickly handed over their tasks and came along - were those soldiers not well-trained? They actually abandoned their patrol duties to come here?

Although this is a good thing in terms of the result, but thinking about the essence, Yi Ning felt it necessary to remind their captain and let them train well.

This time they actually did a good thing, but what if the person who called them was a spy?

What if there is a loophole in the defense and someone takes advantage of it?

Needs lessons.

The soldiers on the first floor suddenly shuddered, and some of them sat on the ground or stood aside to think about their lives.

A young man who had woken up earlier reminded them, but they didn't go out. They just couldn't help sighing that they were unlucky.

When they saw Yi Ning and Yu Youyou coming down, they all looked at them expectantly, hoping that they had found a solution.

"Are you all awake?" Yi Ning raised an eyebrow. "It's just a good opportunity for me to tell you that you will be staying on the second floor for the next two days. As for now, come over here and I'll check you out."

The soldiers lined up obediently. The first soldier to check carefully asked, "Healer Yi, when can we leave?"

"You can leave when you're ready." Yi Ning looked up at him, "Next."

"Oh, okay."

The soldier walked away obediently and let the second person come up.

Then came the third and the fourth.

I checked them one by one, and the people behind me were very honest and didn't ask any more questions, until the last one -

"Healer Yi, why are we losing our minds?"

Hearing this question, Yi Ning looked up and found that it was a young man who looked a little unfamiliar.

This person shouldn't be a warrior, his temperament is a little too gentle.

"If I knew, I could cure you." Yi Ning examined him as usual, then waved him off, "Okay, go and have a good rest first, and leave the rest to me."

"Yes, Zhou Zhou, you don't have to worry. Sister Ning is so powerful, there will definitely be a way." Yu Youyou also nodded seriously.

That’s right, the one who asked the question just now was Zhou Zhou.

Apart from Yu Youyou and Yi Ning, Zhou Zhou should be considered the most special person.

He was worried about Yu Youyou, so he followed Yu Youyou for a while, and ended up being involved in this matter.

Really...

"But the clinic..." Zhou Zhou was a little embarrassed. "I can't contact the outside world right now. Miss Yu, can you help me talk to Doctor Tang?"

All suspects identified will be automatically locked and unusable by the optical computer.

Because of her special identity, Yu Youyou can still use the optical computer, but she is under surveillance.

But before she could say anything, Yi Ning said, "I'll help you."

She directly turned on the light brain, contacted the deputy director of the medical clinic, and told her that Zhou Zhou was temporarily staying with her and could not return.

Zhou Zhou breathed a sigh of relief when he saw this.

He had a huge smile on his face: "Thank you, Healer Yi."

"You're welcome."

Yi Ning hung up the phone and nodded to Zhou Zhou.
