The other party thought for a moment and said, "Now those people may still be secretly observing you, you can wait and send me a photo of the front and back of the note, and our people will follow up." Tomorrow you go to the Friendship Pass on time. ”

Huang Rui said: "Okay, I'm sorry for you." ”

The other party said: "Don't bother, this is our job, thank you for your support and cooperation with our work, please rest assured, we will protect you and your family's safety, goodbye." ”

The next morning, Huang Rui excused himself to attend a class reunion, so he took a penguin Didi special car to Nanning East Railway Station.

After buying a high-speed rail ticket to Pingxiang, Huang Rui took a high-speed maglev train running in a vacuum pipeline and soon arrived in Pingxiang City, on the border of southern China.

After eating a bowl of Vietnamese chicken noodles at a roadside shop in the city, Huang Rui took a special car to the equally crowded Youyiguan (formerly known as Zhennanguan) scenic spot.

With the crowd of people touring the scenic area, Huang Rui came to the ancient city gatehouse, took a selfie under the three big characters of "Friendship Pass" like ordinary tourists, walked to the right side of the city gatehouse, and began to climb the stairs along the city wall.

At this time, the earphones in Huang Rui's ears sounded Director Zhang's voice: "Dr. Huang, the young man in blue behind you and the girl in green in front of you are our colleagues in the Guangxi Hall, once there is a situation, they will try their best to protect you." After you stop, they will also pretend to take pictures for a while, and then they will be replaced by a staff member disguised as an elderly couple. Then it is replaced by a black couple, so you can stay there for ten minutes. Ten minutes later, withdraw anyway, I'll be waiting for you in the car just now. ＂

When he climbed to the fiftieth step, Huang Rui stopped, turned around and smiled apologetically at the tourists behind him, faced the wall, stood against the battlements of the city wall, raised the white Huawei bracelet in his hand and looked at it, it was exactly 11:55.

Waiting for the pair of staff disguised as old men to pretend to stop by Huang Rui's side and take pictures of each other, the time was just twelve o'clock.

At this time, Huang Rui saw several white lights of different durations flashing in the dense forest on a mountain a few kilometers away on the other side of the border.

As a senior programmer, Huang Rui quickly translated the signal into words in his heart: "Cross the port." ＂

Director Zhang's voice sounded: "Dr. Huang, you can choose not to go, the counterparts on the other side have been contacted in advance, and the net can be closed, of course, if you go over voluntarily, the effect of solving the case may be better, if you are willing to do so, our people will continue to follow you over, they will use their lives to protect the safety of our citizens, you see... ＂

Huang Rui turned around and continued to tour for a while quietly, and met a security guard on duty, so he asked: "Comrade, may I ask where to go for what procedures to go for half a day on the opposite side of the customs tour, and how much handling fee needs to be paid?" ＂

The middle-aged male security guard smiled: "Hello, if you have a passport for half a day, you can quickly pass the customs by brushing your face, and you will have no problem playing for ten days or eight days." If you don't have a passport, in addition to brushing your face, you also need to sign a sign, and you have to come back before eight o'clock in the evening, so as not to trouble the brother of the customs to urge you to come back, as for the charge, this is not charged, after you pass, if the staff on the other side asks you to tip, don't give, if you have something to call 110 in the country. ＂

Huang Rui nodded and said, "Thank you, then I'll go over and play." ＂

As Huang Rui walked down the road he came from, Director Zhang said: "Dr. Huang, thank you for your strong support, but rest assured, now that the relationship between the two countries is very good, my colleagues over there will definitely do their best to protect you like us." I just hope that in case something unexpected happens, you can immediately follow my instructions. ＂

Walking down the stairs of the city wall, Huang Rui walked through the city gate, first found the toilet in the scenic spot for convenience, and then walked towards the port with the flow of tourists.

After crossing the border unhindered, Huang Rui first walked along a small street dominated by shops selling Vietnamese specialties for a while, and then turned into another street similar to a food street, found a café that looked more pleasing to the eye, and walked in.

A young woman with a darker complexion greeted her, smiled and said, "Hello raccoon, Xiansen, ask the Western pharmacy for a shoe." ＂

Huang Rui smiled and said, "You, do you speak Chinese?" ＂

The woman said, "Swing strictly." Oh, I heard about it, and I also took a tour of the Ximin Rent School. ＂

Huang Rui said: "Ao, I understand, this, a graduate of Guangxi University for Nationalities, please help me order a latte." ＂

The woman said: "Consume, you choose the song micro-words, and wait for a while." ”

Huang Rui nodded, chose a position against the glass wall and could see the street outside, and after a while, the woman brought a cup of coffee and said, "Xiansen, Qingmanyong." ”

After a while, a little boy about six or seven years old walked outside the glass wall and knocked on the glass to remind Huang Rui to look at him.

Huang Rui nodded and shouted, "The boss pays!" ＂

A bald middle-aged man walked over and said, "Okay, the price is ten yuan, do you want cash or WeChat Alipay?" ＂

Huang Rui said with a smile: "It's cheaper than in China, WeChat is good, are you from the Northeast?" ＂

As soon as the man raised his hand, a QR code was projected in front of him, and said with a smile: "It's not a place, it's all a small business, this Gada has a large flow of people, small profits and quick turnover, half of the shops here are opened by our Northeast people, isn't it warm here, we all love to take root here." However, I would like to assure you that the food and drink on these streets are all authentic local products, just like I just recruited a Vietnamese schoolgirl. ＂

Huang Rui said: "Yes, I wish you a prosperous business, my computer, WeChat scan code, transfer ten yuan." ＂

After saying goodbye to the bald boss, Huang Rui walked out of the coffee shop, and the little boy who had been waiting outside for a long time said in English: "Follow me." ＂

After walking down the street for a few minutes, the little boy turned onto a side road and continued to walk towards a place where the population was becoming less and less crowded.

Director Zhang said: "Dr. Huang, it's okay, just follow along, our satellites and high-altitude drones are staring at you, there are also our people among the tourists behind you, and in the woods on the opposite mountain, there are three adult men, and the snipers of the Vietnamese public security have also targeted them." ”

Huang Rui took a deep breath and followed the little boy to continue walking, and soon came to the foot of a hill.

The little boy stopped and said, "They let you go up the hill along this path, and my mission is done." ”

Huang Rui asked in English, "You don't know them?" ”
