Hattori Mina came out of the kitchen and saw Jiang Xinyu still looking at the postcard. She smiled and said, "They say letters from home are worth ten thousand yuan. It seems true. You have been looking at a postcard for so long."
Jiang Xinyu smiled and said, "It was sent by a classmate."
"Can I take a look?" Hattori Mina sat next to Jiang Xinyu.
"Of course, the postcard has been seen by everyone who has dealt with it." Jiang Xinyu handed the postcard to Hattori Mina.
Hattori Mina read both front and back, and praised: "The cruise ship is very beautiful, and your classmate's calligraphy is even more beautiful...ah sneeze!"
"Did you catch a cold?" Jiang Xinyu asked with concern.
"No...sneeze!" Hattori Mina smelled the postcard and couldn't help but sneeze again. She quickly put the postcard down.
"What's wrong?" Jiang Xinyu picked up the postcard suspiciously and smelled it, without any discomfort.
Hattori Mina explained: "I am naturally allergic to chemicals, maybe because postcards contain such things."
How could a postcard be exposed to chemicals?
"It doesn't matter to you, right?"
"As long as it's not a highly concentrated chemical, it'll be fine... Okay, the teacher is ready. Can I start studying, Jiang-san?" Hattori Mina said seriously.
Jiang Xinyu smiled and said: "It's okay to report to Teacher Mei Nai."
The two spent the day happily without being disturbed. After dinner, Jiang Xinyu drove Mina Hattori home.
Hattori Hikoo's residence is less than a few hundred meters away from the gendarmerie. Even so, for safety reasons, a guardhouse was set up outside the courtyard gate, with four gendarmerie on duty every day.
Arriving at the door of her house, Hattori Mina got out of the car, turned around and asked, "Xinyu, can I call you during your work hours?"
"You can do it at any time." Jiang Xinyu said with a smile.
"Goodbye." Hattori Mina waved and walked briskly into the courtyard.
This is the best state for an intelligence agent to enter the dormant period. Every day life is step by step. No matter who is monitoring him, there will never be any doubts.
"I'm back." Hattori Hikoo said standing on the second floor platform.
Hattori Mina said in surprise: "Brother, why did you come back so early today?"
Watching Jiang Xinyu's car gradually go away, Hattori Hikoo said: "The military police have nothing to do today...have you eaten?"
"Have eaten." Hattori Mina stepped into the living room.
After a while, Hattori Hikoo came down from upstairs, took a look at his sister's radiant face, and said, "Where did you go to play today?"
Hattori Mina picked up a piece of sushi on the plate and put it into her mouth. While eating, she said, "I told you yesterday, and you still ask."
Hattori Hikoo frowned and said, "Have you not eaten yet?"
"I can't help it, I'm greedy when I see sushi." Hattori Mina said with a smile.
Hattori Hikoo sat down cross-legged and said casually: "If there is anything interesting today, please tell me."
"I'm twenty years old, and I'm still asking questions like a child..." Mina Hattori rolled her eyes at her brother and said dissatisfied.
"Brother cares about you... By the way, I asked someone to buy you medicine to treat allergies in Germany. It may be delivered in a month or two."
"Is the German medicine easy to use? I'm allergic again today."
"I told you a long time ago not to come into contact with chemicals, why don't you remember it long ago?"
"Who would have thought that a postcard would contain chemicals..." Mina Hattori muttered.
Hattori Hikoo stood up and said: "You must pay more attention in the future. Don't stay in the hospital for several days like the time in RB."
"knew……"
…………
When Jiang Xinyu returned home, he immediately checked the postcard carefully under the lamp. It was indeed Ouyang Boran's handwriting. The signature date was two months ago. The mail from ZJ to Yanjin could be delivered within two months.
This is already a very good efficiency.
He knew that there was an imported chemical that could be used to write secret letters, and that the liquid needed to develop film could reveal the handwriting.
When I was trained in Jizhong Special Branch, there was no such chemical. This knowledge was specifically explained during the short-term training given to the police station by the Special High School Course. It was mainly to remind the police of issues they need to pay attention to when checking mail.
Jiang Xinyu took out the liquid for developing film from the cabinet and soaked the postcard in it. A few minutes later, a line of blue fonts appeared: Please be sure to go to table 3 of Chunlai Tea House for a joint at noon tomorrow. This postcard is the secret code for the joint!
!
Jiang Xinyu carefully took out the postcard and put it aside to dry. He was full of doubts in his heart. He knew Ouyang Boran very well. This man was timid and fearful. He was a standard obedient citizen in the occupied area. He would never join any anti-Japanese organization.
That is to say, someone wants to get in touch with me through this postcard. Who could it be in such a secret way? The secret letter is not signed, so there is no way to tell which party is contacting me.
And the most critical problem is that he is currently in a period of dormancy. Neither the military commander nor the underground party will come to contact him unless they encounter a particularly important situation.
At noon the next day, Jiang Xinyu drove to the vicinity of Chunlai Tea House. The postcard was on his body. After it was dried, the blue writing no longer existed. It could only be revealed after soaking it in potion.
Jiang Xinyu has his own plan. He will not meet the person at table 3. He will only go in and have a cup of tea, come out after seeing clearly what kind of person he is, and then find an opportunity to contact Sun Shiming to verify this person's identity.
If it is not someone from the underground party, then it is undoubtedly someone from the military command. When the time comes, he can notify Ge Quan and ask the ZQ headquarters to show his caution.
Jiang Xinyu got out of the car and walked into Chunlai Tea House.
Sitting at table No. 3 is a man in his thirties, wearing an iron-gray suit, a black top hat, and a pair of round glasses on the bridge of his nose. He looks like a reporter from a newspaper or a foreign trade company.
comprador.
Jiang Xin ordered a pot of tea and a plate of snacks, sat down with his back to table No. 3, and read the newspaper he bought on the way. He planned to stay for another ten minutes before he could leave naturally.
There was a mirror at the entrance of the teahouse to facilitate guests to organize their appearance. Jiang Xinyu saw that the time was almost up, waved and called: "Dude..."
He glanced inadvertently and saw the look in the mirror of the person at table No. 3. It was a deliberately evasive look!
Jiang Xinyu suddenly realized that he had made a serious mistake!
"Sir, what do you need?" The waiter had already walked over.
