There is no handwriting. For an ordinary person, this may be a prank, but for a person with rich experience in agents, no word is more important than a word.

Find iodine (usually hotels have this kind of medical medicine box, which can be used to treat some minor damage and disinfect), dip a cotton ball in iodine, and apply it bit by bit on the blank letter paper.

This application is also regular, not randomly applied on it, but follows a agreed trajectory.

This can play a certain role in keeping confidentiality if such secret letters fall into the hands of those who know how to do things.

“…”

The secret letter is written using rice soup, which will appear after encountering iodine. When the iodine is dried, it will disappear.

Wu Xiaoyun looked at the contents on the letter, her face changed slightly, and then she lit a match and turned the letter into ashes.

"Sister Yun, have you gotten up?"

"Tongtong, come in." Hearing the voice outside the door, it was Tongtong. Last night, she went back to the hotel with her.

"Sister Yun, what does this taste like?"

"Haha, it doesn't taste much." Wu Xiaoyun smiled slightly, and the smell emitted by the open iodine bottle on the table.

Tongtong obviously saw it. She also had special training. When she saw the ashtray on the table, she understood.

However, if you shouldn't ask about such things, this is the rule.

"Sister Yun, let's go for a meal. I know there is a nearby house with soup dumplings that are made well. We will buy them and bring them to Xiaohai after eating?"

"Well, okay, go and call me, old demon, let's go together." Wu Xiaoyun nodded. Although he was thinking about problems in his mind, people always had to eat.

"The old demon went out early in the morning and hasn't come back yet." Tongtong said with a pout.

"oh?"

Wu Xiaoyun frowned slightly and went out early in the morning. Why didn’t he tell him? Are you afraid of waking him up?

"Sister Yun."

"It's the old demon who is back."

"Sister Yun, Dou Fei is here." The old demon pushed the door and came in, wearing a gray jacket, looking like a little follower for the young lady on the beach.

"Tongtong, let Dou Fei take you to the hospital later. If you have nothing to do today, you will be in the hospital." Wu Xiaoyun ordered.

"Sister Yun, where are you?"

"I have something to do. If I have something to do, I will call the hospital to notify you." Wu Xiaoyun said.

"Oh, I understand, but I want to go home, check out Sister Lan, and get some things by the way." Tongtong had already agreed to leave with Wu Xiaoyun, but she just left Lan Xin alone. She couldn't bear it. After all, the two sisters have been together for two or three years. Tongtong worked in Paramount. If it weren't for Lan Xin's secret protection, there would have been no bones left that people would have eaten.

"Well, let Dou Fei be with you, what heavy work can he help me with?" Wu Xiaoyun nodded.

After having breakfast at the soup dumpling shop introduced by Tongtong, I packed up and bought several servings, including those taken back for Lan Xin, as well as those from Xiaohai and Ping'er from the hospital.

The four people separated on the street, Wu Xiaoyun and Yao Heizi were preparing for the morning joint, Dou Fei pulled Tongtong to the house first, and then to the hospital. After Dou Fei sent Tongtong, he would also come over to meet Wu Xiaoyun.

Hao Bin returned home, and Shan Bo knew that this son was not a person who lived a peaceful life. If he hadn't been a lame leg, he wouldn't have stayed at home for three years. Now that Miss Yun is back, according to his personality, he must have continued to follow him.

Shanbo did not stop him, but as a father, he couldn't bear to let his son take risks, but he didn't want to stop him. Wu Xiaoyun's father was kind to his family back then. This kindness must be remembered for a lifetime, and he must not forget his roots in life.

What's more, Wu Xiaoyun also said that she could find a doctor to help Hao Bin cure her legs. Can he let his son be limp for the rest of his life?

Whether it is repaying kindness or gaining a future, Shanbo has no reason to stop his son.

Before leaving, Hao Bin kowtowed three times to his father and said, "My son is unfilial. If he can come back alive, he will definitely give you a care for his old age."

Hao Bin did not plan to say goodbye to his mother. He didn't want to see his mother's worried eyes, for fear that he would be soft-hearted.

Under the umbrella, Wu Xiaoyun was holding a newspaper in her hand, resting her feet on a stool, and the shoe polisher worked hard to wipe it.

Although the shoe shiner is the lowest class in society, he recognizes the quality of leather shoes. This is a pair of women's leather boots and imported French calfskin. This pair of shoes is still the latest style. Not many noble ladies and socialites in the entire Shanghai can wear this.

Therefore, the distinguished guest in front of him must be the lady of the rich family, but he likes men's dressing, which is also a new trend that has been popular in Shanghai recently.

"Miss, Hao Bin is here." The follower Yao Heizi trotted from across the road and whispered in Wu Xiaoyun's ear.

"Take him to buy a few clothes first, and then go to Chunfeng Teahouse." Wu Xiaoyun ordered.

"Yes, are you planning to let Hao Bin contact them first?" Yao Heizi asked more.

"Um."

"I understand." Yao Heizi nodded and went to do business.

"Okay, how much?"

"Young Master, Cheng Hui, a corner, thank you."

Wu Xiaoyun took out a 500 cents of legal tender from his pocket and handed it to the other party: "Your skills are good, so you don't need to look for them."

"Thank you, Master, you are a good person, and you will live for a hundred years..."

Wu Xiaoyun had already walked away, and the shoemaker was still bent over and kept saying words of thanks to her back.

Spring Breeze Tea House.

"Young Master, you are here, what tea to drink today?"

"Come a pot of Longjing."

"A pot of Longjing, table No. 3 upstairs." Dr. Tea shouted, and when Wu Xiaoyun sat down, Dr. Tea brought a pot of brewed Longjing tea.

On a hot day, the business in the teahouse was not good. The ceiling fans above their heads were creaking and creaking. Although there was wind, they didn't feel that it was cool. Fortunately, the sun was too poisonous today, and there were still many people on the streets. After all, it was a bustling beach.

"Customer, do you want a towel?"

"No need, give me some melon seeds or snacks," Wu Xiaoyun shook his hand and ordered.

"Okay."

Hao Bin and Yao Heizi, who had changed their clothes, also came up and saw Wu Xiaoyun who had arrived. They were stunned for a moment, but he knew what he was going to do from Yao Heizi. His eyes just paused for a moment, and then walked towards another table.

Ordered a pot of tea.

After Yao Heizi came up, he went down again. His current identity is Yao Bin's follower, and he also had to monitor the environment around the teahouse.

Wu Xiaoyun has different identities now. Although the two people we met today were her subordinates, these two people are different from Hao Bin and the others. Three years have passed, and it is hard to say whether they can still trust them. Moreover, their past identity background is very complicated, so you have to be careful.

The appointment time was 10 o'clock in the morning, and now it is almost time to arrive.

"The graceful and romantic Du Shiniang fell in Pingkang..."

A soft Wu dialect Pingtan "Du Shiniang" has a beautiful tune and is heartbroken and burst into tears.

Dingdeng...

There was only a sound of stairs, and a young man walked up, his round face was shining with bright water, and his eyes were rotating.

Seeing a person sitting at the agreed position, the young man gently pulled down his sunglasses and walked over with a brisk step.

"Oh, isn't this Hao Ge'er? Why? You are the one who asked me to come today?" The young man sat down.

"Xiao Weizi, we haven't seen each other for a long time. Can't we ask you out for a tea?" Hao Bin smiled.

"Obviously, how could I not give your Brother Hao's face? This outfit is good and high-end goods, but you just get rich?"

"Haha, it's nothing. Looks like you are so greasy. It seems that you are doing well with foreigners?"

"I am just a errand runner. No matter how good I do, I am still an errand runner." Wei Jia smiled embarrassedly, picked up the teacup on the table and poured himself a cup, and took a sip.

"Sister Yun is here in Shanghai."

"Brother Hao, have you not forgotten yet?" Wei Jia persuaded, "You, stop asking for trouble, that person will not like you."

"I know, I don't think about it anymore." Hao Bin nodded, "Where is Lao Yu, why didn't he come with you?"

"He has to wait a while. The school has a lot of things and he has to finish the class before he can get here."

"Has Lao Yu gone to teach?"

"Yes, otherwise, with his material, wouldn't it be better to retake his old career?" Wei Jia smiled.

"I really didn't expect that one of you became a comprador of a foreigner and the other became a teacher." Hao Bin smiled bitterly.

"Actually, we sometimes..."

"Sister Yun is here, she asked me to ask you out. Do you understand the meaning?" Hao Bin said. These two are partners and intelligence brokers who make a living by selling information. Later, after being incorporated by Wu Xiaoyun, they are specifically responsible for intelligence collection.

These two people did not have any moral integrity and dared to take on any business or do it.

But these two people are cunning enough, so they have not been killed in recent years, which is a miracle.

"The team has all been dispersed. We agreed to go our separate ways at the beginning, but now we suddenly said we would get together again. This makes us very embarrassed." Wei Jia showed a hint of embarrassment.

"Xiao Weizi, when we joined, we said everything, have you forgotten?" Hao Bin asked unhappily.

"But it's not that we want to disband the team. Sister Yun insists on bulk goods. What can we do?"

"You are unwilling to come back, right?"

"Brother Hao, you can't say that. I was really happy during those days with Sister Yun. I was full of energy every day, but now it's different."

"The Japanese warships are shining and promoting martial arts on the Huangpu River every day. We ordinary people are hungry and bullied. Wei Zi, you are also a Chinese. Don't you empathize with it?" Hao Bin couldn't help but question.

"Brother Hao, you are still as passionate and full of righteous indignation as you used to. I know you really want to go to the battlefield to kill the enemy and serve the country, but you are like this yourself, why can't you be more realistic?"

"Wei Zi, you really don't plan to come back?"

"What can I do when I go back? I am now doing things for foreigners and earning at least three or four hundred fiat currency a month. How much can you earn in a month when you sell tickets in the cinema?"

"Money, money, you fell into the eyes of money. Is it because of money that you can even betray your ancestors?"

"Brother Hao, I, Wei Jia, still has a bottom line in life. At least I will not do anything about my ancestors, my compatriots and the country. Otherwise, Sister Yun would have shot me to death at the beginning." Wei Jia retorted seriously.

The atmosphere was a little nervous, and Hao Ge'er was obviously not a good conversation expert.

"Where is Lao Yu, why haven't he arrived yet?"

"I don't know. He will definitely come unless there is an urgent matter." Wei Jia was also a little anxious.
