Hearing this, Liu Qingqiu had nothing to say, nodded and walked in with him through the back door of the restaurant.

This Mingxin restaurant seems to have a back door secret passage at the beginning, and I don't know what the original owner was hiding in the beginning, Lin Cheng and Liu Qingqiu followed the slightly dim secret passage, and they went up to the second floor of the restaurant without even touching anyone.

Standing on the edge of the protective fence on the second floor, Lin Cheng glanced down and found that there were not many guests in the restaurant at this time, thinking that it should be snowing heavily, and most of the residents of this paper street were poor, so there were not many people who could come to the restaurant to consume if they were fine.

"They should be inside, you wait here for a while, I have to go over and make the code first, otherwise it will be easy to conflict."

Seeing that Lin Cheng was looking at the situation in the restaurant at this time, Liu Qingqiu whispered two words to him, and then walked to the door of a private room not far in front, raised his wrist and gently knocked on the door three times, and then after waiting for two seconds, he knocked three more times.

"Squeak-"

As the knock fell, the door of the private room was suddenly opened from the inside, and Liu Qingqiu hurriedly waved after seeing the door open, and then the two quickly flashed into the house!

"Who, Lao Liu?"

At the moment when Lin Cheng and Liu Qingqiu flashed into the house, a very familiar inquiry suddenly came from the depths of the private room, and the middle-aged man known as Lao Liu did not answer, just nodded to Liu Qingqiu and Lin Cheng with a smile, and then flashed out of the room!

"Huh?"

Seeing that Lao Liu went out without even saying hello, Guan Peng was suddenly inexplicable, and was about to get up to chase after him, but he was instantly stunned after seeing the appearance of the two people who entered the house!

Lin ...... Lin Cheng?! And also...... Mrs. Liu?!!! ”

Seeing these two people appear in front of him at this time, Guan Peng was stunned, pointing at these two people who seemed to have descended from the sky in front of him, and he didn't seem to even be able to say anything with his mouth wide open!

"Why, it's only been a long time, Brother Guan won't be so surprised, right?"

Seeing Guan Peng's ghostly look, Lin Cheng couldn't help but chuckle, walked to the dining table and teased Guan Peng while pouring himself a cup of tea.

Liu Qingqiu was emotionally charged at this time, as Guan Peng's previous employer and relative, her feelings for Guan Peng were much more complex and profound than Lin Cheng's, this righteous man was calculated by her at the beginning, although she was benevolent and righteous to the other party later, but after Lin Cheng's lesson that night, she was a little unable to look directly at each other's eyes.

"No...... No, how did you end up together?! If I'm not mistaken, Brother Lin should have gone all the way south at that time, why did he suddenly appear in Pingcheng again?! ”

After a period of buffering, Guan Peng gradually regained his composure, and asked Lin Cheng with an incredible face, after all, the current traffic conditions are far worse than before, if a person in the south wants to reach the north, unless there is a special plane from the military department, otherwise it will take a few months to catch up, and at the same time, he must have enough luck not to die on the way!

"This matter is a long story, I will talk to you in detail if I have the opportunity in the future, we came to you today mainly for Professor Fang's business."

Although Guan Peng was still extremely shocked, Lin Cheng didn't intend to waste time with the other party in this matter, and said straight to the point.

Hearing Lin Cheng's words, Guan Peng looked stunned, and then suddenly showed an expression of sudden realization, clapped his palms and said: "I said that Lao Liu, who never gangs up on weekdays, suddenly wants to invite me to drink, it turns out that you are the ghost behind your back!" Really, I thought I would be able to take a vacation and have a good drink......"

"Settle Professor Fang's affairs, I can drink as much as you want!"

Hearing this, Lin Cheng couldn't help but cry and laugh a little, Guan Peng looked like he was suffocated in the military department, otherwise he wouldn't have been fooled out of the army with a meal.

And Liu Qingqiu calmed down after the initial embarrassment, and stepped forward to help: "That's right, Lin Cheng came to Pingcheng this time specifically to find Professor Fang, which is why the two of us are together, after all, he is a newcomer who wants to find someone in Pingcheng is tantamount to looking for a needle in a haystack, fortunately, I still have a little relationship with your military department, so I finally fooled you out, in order to find you, Lin Cheng and I haven't rested for several days, Professor Fang treated you well before, You have to help us if you are reasonable! ”

"You ...... What are you talking about? ”

Seeing that the two people in front of him looked worried that they were unwilling to help, Guan Peng looked angry, slapped the table vigorously and said: "You and Brother Lin are my Guan Peng's life-saving benefactors, Professor Fang has the grace of meeting me again, even if I Guan Peng is killed, I will never frown an eyebrow in this matter!" ”

As he spoke, he seemed to remember something again, his expression suddenly darkened, he sat back in his chair with a "plop", and said with a gloomy face: "But Mrs. Liu, you should also know that Professor Fang was named by the military department to leave, no matter what way you look at it, the three of us are not qualified to negotiate with the behemoth of the military department, let alone go to war!" Professor Fang and Miss Fang have not had any news since they were picked up by the military department, and after I separated from you, I was directly assigned to the guard group, and I can only deal with the courtyard wall every day, even if I have tried my best to ask someone to inquire, after so long, there is no other news except that Professor Fang was taken to the Pingcheng Research Institute......"

"Wait, Heijo Research Institute?"

Hearing this, Lin Cheng's eyebrows suddenly raised, and he hurriedly waved his hand to interrupt him, "What is this place?" Do you know where? ”

Hearing this, Guan Peng shook his head helplessly, "All the institutions linked to the 'courtyard' in Pingcheng are first-class secrets, except for the core high-level executives, outsiders are not qualified to know about it......"

"This ......"

Seeing that Guan Peng didn't even know the specific location of this Pingcheng Research Institute, Lin Cheng couldn't help frowning and turned his head to look at Liu Qingqiu.

Seeing Lin Cheng's eyes, Liu Qingqiu spread his hands and put on an expression of helplessness.

"Actually......"

Seeing that these two people looked extremely disappointed, Guan Peng felt very uncomfortable, after all, these two people came specifically for Professor Fang, but at this time, they didn't even know where they were, and they wouldn't feel comfortable in anyone's heart, so they could only open their mouths and comfort: "Actually, think about it from another angle, Professor Fang is also a national treasure-level biologist after all, although there will be many restrictions on his actions, but he should be doing well in other aspects, and the military department is basically unlikely to embarrass his old man in terms of material......"
