For the Sound and Sound Department, the most critical thing about the intelligence system is the transmission line.

Generally, the commonly used ones are flying pigeons and horse racing. In the enemy's territory, they are transported by necessary caravans, supplemented by flying pigeons.

Even if it is a flying pigeon, three are usually used together. After all, there are too many natural enemies of birds, and even humans are one of them. Given this, they are basically used only in emergencies.

This emergency military message came from Tokyo and went straight to Suizhou, and then came to Dengzhou and Xiangzhou. After two days, it finally arrived in Jiangling.

The messenger had just arrived in Jiangling, and Feige sent a letter to Changsha.

"Gululu" A gray-white dove spread its wings and flew past the tall Changsha City. It tilted its head and wandered in confusion. It hadn't come back for several months, why has it changed so much?

There are trees everywhere and birds everywhere. There are many birds around my house. No, it is impossible. My house has just a few brothers, and it is impossible for other birds.

This is not my home, it must be...

The capacity of the cerebellum was really low. After running several laps, it finally saw a few gray-robed figures. After running down, it found familiar cages, bird food, and tiles that made marks on peeing.

"This bird is stupid!" One of the gray robes took out the bird's food and said.

"No one in the bird is reliable, but convenient!" Another man took out the paper letter from the bird's legs, then quickly left, and came to a study with a large number of people. Everyone was wearing gray robes and began to compare words.

After all, the Sound of the Shooting Department has no judicial power and cannot show the majesty of the Jinyiwei in the back. In order to inquire about information, the gray robe and low-key become the best choice.

Soon, he translated it.

His face changed instantly.

Quickly reach the depths of the courtyard, where it is the core department of the Sound and Sound System, there are only a few of them here, and Wu Qing, the commander of the Sound System.

After reform, eight courtyards were established, and the Second Court was in charge of the intelligence supervision of various countries. He hurried over and knocked on the door.

"What's the matter?" A sound rang inside.

"Urgent news from Song State!"

"Come in--"

Soon, he came into the yard and saw the sharp-eyed envoy of the yard and submitted information.

"Hmm?" When Chuyi saw this, the yard was shocked and quickly stood up: "Come with me and go see the commander!"

"No need, I'm here!" As soon as he finished speaking, a thin young man walked in, took away the information directly, and looked up intently.

The yard was shocked and quickly bowed down.

"The letter was copied from the pigeon that just arrived. This is a letter from the pigeon!"

Wu Qing then raised his head, read his letter carefully, and then said slowly: "That's right, you're very accurate in comparison!"

He had long been familiar with the codebook, especially about the Song Kingdom, and he knew it very clearly. He didn't need a codebook at all, he just translated it.

"Come on horses quickly, I'm going to the palace!"

Wu Qing whispered, after cleaning up, he hurried out of the yard.

Because of the critical department, the Sound of the Shooting Department was located very close to the Imperial City, only two or three miles away, but Wu Qing couldn't wait for this time and rode his horse away directly.

Everyone in the entire yamen did not care about this and still handled the news in an orderly manner. Every ten days and half a month, the commander always had to rush on the street, and they were already used to it.
