At this moment, the sound of chaotic footsteps was heard, and the expression on the man's face froze instantly.

But calm was soon restored.

The person who came was the guard who was protecting Gu Bei. He was in plain clothes. Apart from his resolute demeanor, he looked like an ordinary person.

But it would be even more suspicious if there were ordinary people living here.

He glanced at the couple calmly and walked straight towards Nuannuan.

"Nuannuan, your brother and his friends are looking for you. You've been out for so long, it's time to go back."

Nuan Nuan hugged the rabbit and said hello obediently.

The guard smiled and looked at the man. "You come here to take pictures. It's better not to go there. That's a military base. Photography is not allowed there."

The two of them quickly agreed and said they understood. Nuannuan waved goodbye to them and left with the guards.

Bai Yu looked at their leaving backs with suspicion.

I must have been overthinking it. That person was really worried that the child would come looking for me.

However, from what the child said, he was certain of one thing: there must indeed be a secret laboratory here.

It seems that I need to find time to explore it.

The guard's face darkened after he took Nuannuan away.

"Nuan Nuan did a good job, but you can't run too far in the future. You need someone to follow you. Otherwise, what if you are targeted by bad guys?"

Nuan Nuan nodded - "I have a little robot that my brother gave me to protect me."

She pointed at the little robot that had been a decoration on her shoulder.

"Is that uncle a bad guy?"

The guard already had a plan in mind - "It's hard to say, we have to go back and check to find out."

What Bai Yu didn't know was that everything he said to Nuan Nuan was transmitted to Gu Bei's personal terminal through her wrist. The questions he asked might not be noticed by a child of Nuan Nuan's age.

It was also because Nuannuan was smart and knew what to say and what not to say that he didn't find out any useful information.

But they could quickly detect the probing tone in his words.

Before they returned to the laboratory, Gu Bei had already reported the matter, and the higher-ups were also investigating.

Nuannuan quickly forgot about this little episode and conscientiously embroidered cute patterns on her brother's clothes in the dormitory.

Some are small animals, all of which are images of animals at home.

The chubby smiling Q-version pattern adds a special kind of surprise when embroidered.

Some are plants.

Nuan Nuan embroidered all the succulent plants her brother bought for her, as well as bell orchids, sunflowers, irises, etc.

Anyway, I embroider whatever I think of.

That day, after making a super small pocket-sized sweater for Tang Yuan to wear, Gu Bei came back and told her about the spy.

It was the man who talked to Nuannuan that day. They had guessed it beforehand and then quickly launched an investigation. In just one day, they had found out all the information about the man.

Then, without making any alarm, they kept a low profile and monitored the person, and finally successfully arrested four spies including the man yesterday.

One was also caught at the research institute.

This time Nuannuan has made a great contribution.

"Catching a spy is a meritorious service. This time, you discovered the spy, so the higher-ups have decided to award you a reward."

Nuan Nuan suddenly realized: "I was wondering why that person was so weird."

Gu Bei couldn't help but rub his sister's little head.

"Nuannuan is really smart."

The little girl's eyes sparkled, the corners of her mouth couldn't help but rise, and her voice was soft and humble.

"I'm not that smart. I just remember what you guys taught me. I should be more cautious with strangers and not talk about anything related to my brother."

Although Gu Bei is very proud, he is even more unwilling to let his sister take risks.

So from now on, Nuannuan would have a guard follow her whenever she went out.

Nuannuan is not the type of person who likes to bother others, so in order to reduce trouble, she seldom goes out. Even when she takes the three little animals out for a walk, she just walks around and comes back.

After returning in the afternoon, I moved all the plants outside while the sun was not very hot to carry out photosynthesis, watered them patiently, and moved them back in the evening.

In just half a month, Nuannuan raised the three little pets to be plump and full of energy, and the succulents bought by her brother also grew up to be very beautiful.

Another very obvious change is that whenever Gu Bei wears clothes, you can always see some beautiful and lovely embroidery patterns on the collar, cuffs and hems.

Not only was he envied by his colleagues, he also took photos and posted them in the family group.

Then I received a lot of envious voices, and Gu's father was the most obvious. He called Nuannuan that day and complained that such an old man was still complaining and acting coquettishly to his own daughter.

My sons and nephews all look down on me!

But secretly, she planned to embroider the pattern on her own clothes after Nuannuan returned.

After staying in my second brother's laboratory for half a month, Nuannuan left.

Not to mention Gu Bei, everyone else in the lab is now reluctant to part with the little girl.

"Nuannuan, don't leave. Can't you just live here?"

Gu Bei's teacher couldn't help but grumble: "Gu Bei, can't you just let Nuan Nuan stay here? We can buy whatever you need."

Gu Bei——“…”You guys reacted even more than I did!
