Chapter 396

There is a unique cave in the cave, which is closely guarded.

After Xu he checked his identity and password, Su Haitang also handed over his soldier's card. After repeated cross examination, he was released smoothly.

Turning the winding secret Road, the two finally stopped.

Xu he motioned her to pay attention to the movement of his hand.

"Remember? You can use this secret room in the future. You are only allowed to enter alone. You must keep it strictly confidential, okay?"

"Yes!"

Su Haitang replied seriously.

Xu he closed the door and motioned her to open the code lock independently.

It's no big deal. Su Haitang's fingers flew, pressed the password, and the door opened.

Su Haitang stepped in and looked at the transmitter. His blood began to boil!

She sat over, listened carefully to Xu he's introduction to the specific operation, and soon got started.

Morse code is not difficult, it is difficult to encrypt in the process of radio information transmission.

But it's hard for her. Su Haitang agreed with his grandfather on the decryption method in advance. The music score of "anti war" was combined with the new version of "Three Character Classic".

Both of them are her "original creation", which has not been released yet, but they will be released soon.

The complexity of decryption means the security of information transmission and the improvement of the difficulty level of writing information.

But Su Haitang didn't care.

With space in hand, she can try to write encrypted information at will, not afraid of disclosure.

After the first message, Su Haitang shut down the machine and got up to open the door.

"Learned? Do you want to practice again? Don't worry about dinner. Come to my house when the canteen is closed."

Xu he waited outside. Seeing that she came out so soon, he was slightly surprised and kindly suggested.

Su Haitang smiled and shook his head.

"It's long enough to come out. Go back first to save attention. It's the same to come back tomorrow."

Although aunt's towel was awesome enough, the amount of blood was not too much on the first day, but Su Haitang still dared not delay any longer, for fear that a bloody style would be lost.

Xu he thought of something, his face turned red again, coughed, checked her closed door and took her out.

"Tomorrow I'll take you to get familiar with it. If you don't understand anything, just ask. You'll have to come by yourself in the future."

"Yes."

Su Haitang promised.

They were checked out all the way. Even the metal detector had been checked twice, which was extremely strict.

"Report! Comrade Peng man is snooping outside. He followed you and never left." the outermost sentry stopped Xu He to report.

"I'll get her." Xu he nodded awkwardly and hurried out.

Su Haitang was also very embarrassed.

My sister-in-law is following them?

Do you doubt what she has to do with the battalion commander?

Well, it's hard to explain why a man and a woman avoid drilling a cave.

Battalion commander, take care.

Su Haitang silently gave Xu he some wax and asked the sentry with a dry smile, "is there any other exit?"

She doesn't want to be caught. They appear together and jump into the Yellow River.

"Come with me."

The sentry looked at her sympathetically, took her to the right, walked about three meters, knocked on the stone wall on the right, three long and two short.

The stone wall soon opened from inside and came out alone.

"Take her to aisle 6."

Su Haitang signed on the book, stamped his fingerprints, and walked forward according to the instructions of the soldiers inside.

Turn right 500 meters, go down the steps 300 meters, knock on the door after 420 steps, two long and two short.

The door was opened, the sentry was checked and registered, and the next section of the journey continued.

Su Haitang walked very fast and left the last door in less than ten minutes.

"Chief secretary."

Su Haitang came out, looked around in surprise, and immediately showed a smiling face.

"Go back."

Zhang Yuqing waved and put her back to the dormitory.

"Take this application form back. It's not impossible for your class to have more programs in the singing competition, but try to arrange more comrades to participate. This is not a special concert for someone."
