In the evening, after work, Qin Lang drove at the gate of the group to wait for Yan Shuya, ready to go home together.

Yan Shuya asked Qin Lang to wait for her for ten minutes because her work was not finished.

Sitting in the cab, Qin Lang lights a cigarette and turns on the music with his eyes narrowed.

When there was a lot of gunfire abroad, Qin Lang had fantasized that he would marry a beautiful wife in the future, and she would drive to work and wait for her.

With a wife, a brother and no lack of money, Qin Lang wants to be completely satisfied in his life.

Just as Qin Lang is enjoying his perfect life, his mobile phone rings and the screen shows Yan Tianguo's phone.

He immediately put out the cigarette and sat up straight: "Uncle Yan?"

"Qin Lang, take Shuya home for dinner at night. Remember, don't tell anyone."

"Good." Hang up the phone, Qin Lang immediately confused.

Yan Tianguo finds him and Yan Shuya at this time, which means something has happened to him.

In the evening, Qin Lang drives Yan Shuya to Yan Tianguo's villa.

The villa is cleaned every day. According to the requirements of Yan Tianguo, Qin Lang stops his car far away, and they enter the villa through the back door.

In the living room, Yan Tianguo has prepared a rich dinner.

"Qin Lang, Shu Ya."

Yan Tianguo is in a good mood and hugs Qin Lang and Yan Shuya respectively.

"Dad." The happiest thing to see Yan Tianguo is Yan Shuya.

During this period of time, the kingdom of heaven disappeared like the evaporation of the human world, the phone did not understand, and no one could find it.

Only Qin Lang knows that Yan Tianguo has been in Jiulongwan all the time. He just doesn't know what he is doing and why he is so mysterious.

During this period, Yan Tianguo was obviously old and haggard.

Whenever Yan Shuya asked why he had gone, Yan Tianguo would make up all kinds of reasons to prevaricate.

"Shuya, clean up first. I'll talk with Qin Lang upstairs."

Qin Lang knows that the first play is coming.

Yan Tianguo came back this time to visit Yan Shuya's Yi. It's true to find Qin Lang.

"Dad, what can you and Qin Lang have to hide from me?" Yan Shuya was wronged.

Is this still her father who cared for her as a child?

During this time, she obviously felt that Yan Tianguo had concealed a lot of things from her, as if she had alienated a lot.

"Silly girl, you will always be my daughter. I feel relieved to have Qin Lang by your side." With a smile, Yan Tianguo gives Qin Lang a wink and then goes upstairs.

Qin Lang looks at Yan Shuya for fear of causing her attention and misunderstanding, and immediately follows Yan Tianguo.

They came to the study of Yan Tianguo.

When Qin Lang sat down, Yan Tianguo had already made the tea. The amber tea was steaming hot. Yan Tianguo took a sip and exclaimed, "it's still my own tea."

"Uncle Yan, it's not as simple as tea when you call me up, is it?" Qin Lang puts down his cup and stares at Yan Tianguo.

Yan Tianguo was slightly stunned, put down his tea cup and said with a smile: "it seems that I really did not choose the wrong person. I am brave and resourceful. I will give you Shuya. I can rest assured!"

"Uncle Yan, what are you doing these days?" Qin Lang's voice was slightly angry.

During this period of time, Yan Shuya is in a daze on her mobile phone every day. You don't have to guess that she is worried about Yan Tianguo. As a father, he left his daughter behind and disappeared without a trace. He never considered Yan Shuya's feelings.

"Ah..." Yan Tianguo sighed helplessly.

Leaving Yan Shuya alone makes her worry, and Yan Tianguo is also very uncomfortable.

But for Yan Shuya's safety, he can only do this.

"It doesn't matter to tell you, but you have to promise me that you can't tell anyone, including Yan Shuya." It is rare for Yan Tianguo to have a serious look on his face.

Qin Lang knew the importance of things and nodded.

It turns out that Yan Tianguo has always been the research director of the imperial 503 Research Institute.

Drugs are rampant in the territory of Yan country. Once ordinary people get involved in them, they will live a lifetime.

Therefore, Yan Tianguo was instructed to lead all members of 503 Research Institute to develop a new type of detoxification agent. Through years of research, Yan Tianguo developed a new type of detoxification agent through the synthesis of two opioid receptor agonists.

The kingdom of heaven calls it su pian.

The research on Su Pian has always been carried out in secret. However, there are spies inside 503 Research Institute, and the leakage of information attracts foreign forces to spy.Tang Xin's father, Tang Yi, is an important person in charge of the Institute. That day, foreign forces attacked the Institute. In order to protect Su Pian, Tang Yi gave the molecular map to Tang Xin and asked her to hide it.

And let Yan Tianguo find someone to protect her.

No wonder a lot of Japanese forces have appeared in Jiulong Bay recently. Qin Lang understands this.

"In addition..."

Yan Tianguo wants to talk but stops. It's very difficult for him to get a fishbone stuck in his throat. He takes out a U-disk wrapped in titanium alloy and his face is very heavy: "you give this to Yan Shuya and tell her that no one can know about it, otherwise, her life will be in danger."

"Remember!"

Qin Lang frowned tightly. Things are definitely not what Yan Tianguo said.

Qin Lang's perceptive power is very keen, and the kingdom of heaven must not have told him the truth.

"Uncle Yan, this is the real molecular map?"

Qin Lang pointed to the U disk and asked in disbelief.

Yan Tianguo was stunned and then said with a bitter smile: "Qin Lang, it seems that I really didn't see you wrong."

"Yes, this is the real molecular map."

"What about Tang Xin?"

Hearing the speech, the kingdom of heaven sighed again.

When foreign forces attacked the Research Institute, Tang Yi worried that Su Pian's molecular synthesis map would fall into the hands of foreign forces and gave Tang Xin a fake U-disk. The real molecular synthesis map was still in the hands of Yan Tianguo.

Recently, Yan Tianguo felt that just in case, he chose to secretly transfer the molecular synthesis map to Yan Shuya.

Su Pian's molecular synthesis map is the painstaking efforts of him, Tang Yi and all the people of 503 Research Institute for ten years. He said that even if the kingdom of heaven is dead, it must not fall into the hands of foreign forces.

"Uncle Yan, do you mean that you want Tang Xin to attract the attention of foreign forces?"

Qin Lang's eyes cold down: "do you know Tang Xin?"

Yan Tianguo shakes his head.

"Qin Lang, I know you blame me. That's what Tang Yi means. Tang Yi's view of the molecular synthesis diagram is more important than anything else. At the beginning, he begged me to do so."

"Only in this way can we ensure that the molecular synthesis diagram is infallible."

Bang!

"Fart!" Qin Lang slaps her on the tea table. This is the first time he loses his temper in front of Yan Tianguo: "Tang Xin is innocent. She is just an ordinary girl. You actually push her in front of foreign forces. Do you know how dangerous it will be for her to do so?"

"Qin Lang!" Yan Tianguo also slapped the table: "but what can we do? Once this molecular synthesis map falls into the hands of foreign forces, do you know what the consequences will be?"

Creak.

When they argued, the door of the study suddenly opened.

Yan Shuya is a little absent-minded. Her beautiful eyes are complex and hazy.
