Only that guest kept asking what the ingredients of the skewers at the palace banquet were, which was obviously different from the other guests.

  It would have been fine if he had only asked once or twice, but that person seemed to be very persistent in hearing the answer from him.

  It seems like there is some conspiracy.

  Although the shopkeeper did not know the sage's plan, it was keenly aware of the abnormalities of the guest downstairs.

  "Let the shop assistants keep an eye on that man." Li Mumu said.

  The guests had just come in, and the meals have not yet entered.

  If I leave now, it will arouse suspicion.

  Li Mumu guessed that the other party would not leave so soon, and said to the shopkeeper, "You send someone to call the shopkeeper who runs next to him."

  "Yes." The shopkeeper responded and left.

  Li Mumu said, "Gu Mian, you go back to Gu's house with the driver, pick up Xiu Xiu, and ask her to bring the paintings and paintings with paintings."

  "Yes." Gu Mian also hurried over.

  Liu Lu, the owner of the errand shop next door, arrived first. Li Mumu asked, "When you came in, did any customers outside notice you?"

  The shopkeeper also retired from the army.

  Because I lived in Beijing, I joined the legs in Beijing.

  Because he was a capable person, he became the manager of the shop.

  Liu Lu recalled it carefully, and the scene when he just entered the door.

  Then, he shook his head and said, "No."

  "There is a man sitting at the third table from the entrance, on the left side of the wall. He is wearing a blue cloth and a gray turban. He looks to be in his thirties and has a mustache." Li Mumu said, "You will recognize him carefully later, but don't let anyone find him. I will give you a portrait. You can ask the guys to identify him and follow him to find out where he lives and what his name is. Don't let anyone find you."

  The guys in errand shops are running around on the streets all day long and are the least likely group of people to attract attention.

  Because people can see them on the streets from morning to night every day, the most eye-catching one happens to be the least eye-catching.

  They deliver goods every day, and even in remote alleys, you can see errand boys running errands.

  Moreover, there are many errand runners in the shop, so there is no need for one errand runner to follow you all the time. Instead, different errand runners can take turns.

  This way, even if you follow the other person, it will not be easy for the other person to realize that he or she is being followed.

  There is no need to even track it.

  The city is full of errand boys. If anyone sees him, just write him down.

  "Yes." Liu Lu replied.

  Not long after, Gu Xiuxiu arrived.

  "Third Aunt." Gu Xiuxiu came in and called after closing the door.

  Along the way, Gu Mian told Gu Xiuxiu the general situation.

  The Gu family also did not know the saint's plan.

  Gu Mian didn't know either.

  But Gu Mian knew that the guest was not good at peace, so he told Gu Xiuxiu.

  Gu Xiuxiu entered the room cautiously and closed the door before speaking.

  "Did you see the guest downstairs just now?" Li Mumu asked.

  "Hurry up and glanced at it, not daring to look closely, for fear of being seen by the other party." Gu Xiuxiu said.

  Li Mumu nodded and said, "Just a general impression is enough. I'll tell you in detail about the important features of that person. You can draw it."  

  "Okay." Gu Xiuxiu spread out the drawing paper.

  Gu Mian took a paperweight from his arms and began to grind ink for Gu Xiuxiu.

  Gu Xiuxiu first drew a rough outline, then drew some based on her memory, and then supplemented it based on Li Mumu's description.

  After the final painting, Li Mumu nodded, "There are already seven points similar, which is enough to make people recognize."

  "Xiu Xiu, have you had your meal yet?" Li Mumu asked.

  "Before I came out, the kitchen just started to do it." Gu Xiuxiu said.

  "How about eating with me here?" Li Mumu said.

  "Okay!" Gu Xiuxiu liked to stay with Li Mumu, "Just like I want to eat a skewers too."

  It is now a late time, and there is a barbecue shelf outside.

  Li Mumu asked the shopkeeper for a pen and paper, wrote down what he had found, put the letter into an envelope, sealed it with wax, and handed it to Liu Lu, who was still here. "Show the portrait to the guys in the shop and ask them to pay attention to where this man will end up. Deliver this letter to General Gu at the East Suburb Camp."

  The East Suburb Camp has been conducting military training these days, so Gu Shangqing cannot go home every day like he did in the past few days.

  "Yes." Liu Lu took the portrait and the letter and hurried to do it.

  Liu Lu first brought the portrait back to the running leg shop, and asked everyone to watch it again, and let people send the portrait to the various running legs in Beijing, and the guys recognized people.

  Then he hurried to the camp outside Beijing with the letter.

  After receiving the letter, Gu Shangqing went to see the prince in person and told him about the matter.

  "My wife doesn't dare to send someone directly to the East Palace, fearing that they might be discovered." Gu Shangqing said, "This man is a bit suspicious, so my wife is sending the errand boy to check where he is staying. Once he finds out, he will report to Your Highness."

  The prince nodded. When he received the letter from Gu Shangqing and came to see him again, the man should have left Gu's snack bar by now.

  It is too late for the prince to send anyone to follow him now.

  When the other party's foothold, the prince could send someone to investigate whether the person was suspicious.

  "The restaurant opened by Madam Gu can indeed pay attention to more people." The prince said, "I and the Saint are in the palace, and we can't notice many things."

  "It's just that we happened to meet today." Gu Shangqing said, "These days, my wife has been watching the restaurant every day, thinking that she might run into someone suspicious."

  "Waiting for this, it must be on the reward." The prince said with a funny way, "Mrs. Gu is afraid that it will be faster than you."

  "Chen is willing to support his wife." Gu Shangqing laughed, "After all, from the beginning, Chen did not have the rising of his wife."

  "If women can serve as officials in the court, your official position will be higher than mine." Gu Shangqing said.

  "No wonder Madam Gu risked her life to go to the border to save General Gu." The prince said, "General Gu is so supportive of Madam, and he doesn't care that Madam's achievements are higher than his own. At least I have never seen such a person."

  "General Gu's broad-mindedness alone is unmatched by others. With such a broad mind, his future achievements will be limitless." said the prince.

  "Your Highness, thank you for your compliment." Gu Shangqing said quickly.

  "General Gu, are you going back to the barracks?" The prince asked, "If you are not in a hurry, you can have a meal in the East Palace before leaving. There are still some details that I can discuss with General Gu."

  There are also some things that can require Gu Shangqing's cooperation.

  "Then I will respectfully obey your command." Gu Shangqing said.

  Because the Gu family's grilled skewers were always served at the palace's Mid-Autumn Festival banquet, the business of Gu's snacks and Wangyou Xiaojie became even better after the news spread.

  Needless to say, many people have to taste long lines outside and have to try it.
