Finally returning to the factory, Yu Zhengfeng's first reaction was to look at the door of the factory and whether there were any signs of damage around him.

Seeing that this place was no different from before they left, Yu Zhengfeng finally breathed a sigh of relief.

"Start the communication and tell the Timberwolves that we are back." Yu Zhengfeng directly drilled out of the disguise net, breathing a relaxed tone, and gestured in the direction of the alert ahead.

When they met again, the surprise on Geng Jihui's face could not even be concealed.

"You are finally back. I heard that someone is injured?" Geng Jihui walked over and looked at them.

Yu Zhengfeng pointed directly at Zhang Tiande, "It's a stone, the wound at the airport has been treated."

While he was talking, Geng Jihui also saw Zhang Tiande wearing a bandage, "Why are you back after you're like this?"

Yu Zhengfeng smiled helplessly, "He strongly asked to come back and was reluctant to leave."

Geng Jihui immediately understood and sighed with emotion, "What's wrong with this?"

"But I also saw his injury. There was no big problem. We were short of staff. It would be a pity if such a good firepower player was not there."

Yu Zhengfeng said and looked at him, "But let him rest first in the next two days and take good care of his injuries. When he really uses him, he might be a surprise soldier!"

Everyone was brought back, and Geng Jihui certainly could not refuse. He nodded and asked, "How is it going along the way?"

"Hey, don't mention it, it's simply... passing five passes and killing six generals." Yu Zhengfeng shook his head, "But the person is delivered safely, and the plane will leave tomorrow morning."

"It's good that people are safe." Geng Jihui also felt relieved.

But Yu Zhengfeng looked at him and said, "We really ignored these staff members before, but fortunately nothing happened."

"What's the situation?" Geng Jihui's face changed suddenly.

Yu Zhengfeng subconsciously glanced at the direction of the laboratory, "None of us expected that the laboratory could be rebuilt even without Professor You."

"This is why we will be attacked this time. If the people we escorted are hijacked, then our mission will have no meaning anymore. They no longer need Professor Yu."

Yu Zhengfeng sighed deeply, "I have to say that Professor You is really selfless."

Geng Jihui was also stunned, "Why didn't they say such an important thing earlier?"

"It's no point to talk about these things now. Just think about what to do next?" Yu Zhengfeng sighed helplessly, "Our plan was going to change."

"Yes, we put all our energy into Professor Yu before, but now everyone really can't make any mistakes."

After Geng Jihui said this, he smiled self-deprecatingly, "If they heard this, would he feel that we didn't care about their safety before?"

Yu Zhengfeng also laughed helplessly, but no matter how much he joked, he had to pay attention to this time.

Before, they focused on Professor You, and they were worried that K2's target was her and would try every means to kidnap her. The dangers for others were completely different. In their opinion, K2 would not care about their life or death at all, so the protection methods were completely different.

But now it seems that these people are equally important, so they need to change to other ways of protection.

However, after thinking about it this way, their lives are much less dangerous. Whether it is K2 or other forces, they want to get them and get the experimental results without taking their lives.

But for them such changes, the entire defense strategy will change.

Yu Zhengfeng took almost half of the people away today, and the remaining people stayed here, and the pressure suddenly increased.

It can be said that although they were not attacked like Yu Zhengfeng and others, they were not relaxed.

But compared to Yu Zhengfeng and the others, it was still relatively relaxed. Seeing this situation, Geng Jihui did not arrange their warning directly, but instead asked several people to rest first.

Come to the laboratory with Yu Zhengfeng. Yu Zhengfeng glanced at him and saw that there was no change, so he understood something, "They didn't come out again after they got in this day?"

"Yes, they can rotate before the people you brought away, and now there should be no one to replace them."

Geng Jihui said as he turned to look at the laboratory, "But she is not an iron man, she should come out soon."

"They should have rushed the construction period, it seems that we are not the only ones who are worried." Yu Zhengfeng said, and sighed helplessly.

Instead of waiting for someone here, he came to the rooftop and saw Deng Zhenhua lying alone in the bunker, and suddenly laughed.

I walked over slowly, "How is it, I'm not quite lonely, right?"

Deng Zhenhua glanced at him, "I saw you back a long time ago, why did you have so long?"

"You are not well-informed enough." Yu Zhengfeng sat down with a smile.

Deng Zhenhua looked back at him, but saw a little embarrassed look in his military uniform, "Are you attacked?"

"Yes, there's more than one incident." Yu Zhengfeng looked at him helplessly, "It's a big fate to come back."

Of course Deng Zhenhua knew that he was a joke, but when he heard his words, he was still a little surprised, "Didn't it mean that Bo Ya is not so messy yet?"

"It's true that it's not as chaotic as armed conflict, but what else do they dare not do when we pass by remote mountain roads?" Yu Zhengfeng shook his head helplessly, "Although we are attacked, there's nothing wrong. How are you here?"

There is nothing unusual in the defense area in the factory, and the only thing Yu Zhengfeng is worried about is this place.

I didn't understand what he meant and said directly, "I've been watching it all the time. There was no movement in several buildings, and there was nothing happening nearby."

"I had been worried before that the more I did not have any abnormalities, I felt strange. Now I understand that they have no energy and no man to stare at us anymore."

"If this is true, then what we have to face next may be even more difficult."

As they said, the two looked at each other.

Maybe others don’t understand, but as snipers, both understand that if someone really breaks through, how much pressure will be in such a defensive position.

As the sky gradually became darker, Yu Zhengfeng finally saw Professor You again.

Although she is not a professional soldier, her observing ability is not bad at all. She can see the embarrassment of Yu Zhengfeng and the others at a glance.

He immediately looked at him apologetically, "I'm sorry, I've implicated you."

"Protecting you is what we should do, but some things... have you not explained them clearly?" Yu Zhengfeng stopped being tactful and spoke directly.

Hearing his words, Professor Yu couldn't help but feel a little embarrassed, but he still asked with some concern, "How are they... now?"

"Don't worry, everyone has been sent, and fly back to China at dawn tomorrow." Yu Zhengfeng sighed lightly, but his eyes were staring at her.

Professor Yu coughed lightly, "Sorry, I did hide something from you before."

"It's just that I think... the impact shouldn't be too big, so..."

"You said there is no big impact?" Before she could finish her words, Yu Zhengfeng almost didn't jump up. "If we had known it, we would have been planning to be attacked and make more preparations."

"Our people may not be injured or even almost die!"

Hearing his words, Professor You was also a little surprised and apologized again. Obviously, he really didn't expect the matter to be so serious.

"Why don't you tell us this in advance?" Yu Zhengfeng took a deep breath, "You know we should trust each other, right?"

"We won't go to inquire about your experiment, but it involves safety issues, so why should we hide it?"

Professor Yu shook his head, "I feel that I have told you all the news related to safety, but I didn't expect... these will have an impact."

After she said this, Yu Zhengfeng was speechless. He looked at her helplessly, sat down and said, "What else can you hide from us? Just say it!"

Professor Yu looked at them and finally seemed to have made up his mind, "I think you should know something about them."

"Although these people are my students and colleagues, they all participated since the experiment."

"Although I am in control of the entire process of this project, I have no hidden anything from them. I can trust my students and colleagues."

Professor Yu paused at this point, "Actually, I did this because this experiment is very important."

"If I were the only one who mastered this achievement, once something happened to me, the investment and everyone's efforts over the years would have no meaning."

"So we built a team that others might seem incredible, two teams we have, and each one can re-establish the lab after a problem."

"The people who made you misunderstand that they left were backup personnel, but in fact... they are the main force of this experiment." Professor You said this and looked up at them, "We saw the danger here. Once there is a problem with the laboratory, we must retain all the data in the laboratory and the ability to restart the experiment immediately."

Yu Zhengfeng was really shocked by her words this time. He never expected that such a weak-looking woman would have such a thought of burning her boat.

"You have hidden such an important thing from us, and you have never thought that if something happens to them on the road, not only will your plan fail, but it will even put them in danger?"

Professor Yu's face changed, "I just thought that the fewer people know about these things, the better."

"I also hope to send them out before Boya was completely in chaos. I really didn't expect them to be attacked."

But at this time Yu Zhengfeng suddenly realized something, "You just said that the less you know, the better. How many people know about this model in your laboratory?"

"These two teams in our laboratory, and... there are also investors from Huaxing." Professor You looked at him and said seriously.

Yu Zhengfeng now understood why she hadn't mentioned it, and the girl before didn't say it until she saw the stone injured. Obviously, she realized the seriousness of the problem.

But this secret has always been involved in such a small range, how could the K2 people attack a few ordinary staff members?

"You suspect that their news is leaked, and there should be more than that people who know it?" Geng Jihui also guessed what he meant when he saw that he was silent.

Yu Zhengfeng looked up at Professor You, "You said your staff can trust?"

"Of course." Professor You nodded quickly, "These people followed me for some time, and... their detailed details Huaxing has also checked. They are all trusting to join the experimental group."

Although she had such guarantees, Yu Zhengfeng knew that the investigation of a commercial institution could not be accurate.

If K2 really wants to do something, it would be easier, but in that case, it would be not that they have been doing these things recently, but that people have already been put on.

But there are also contradictions. If people were arranged early, why would you remember to deal with them at this time?

Yu Zhengfeng shook his head and still expressed his doubts.

Professor Yu looked a little ugly after hearing this, "Although I don't believe that there are people like you mentioned among my people, I think I should know why they did this."

"It can be said that no one was optimistic about this research at the beginning. Although it has certain research value, no one thinks we can succeed."
