The conversation between Lao Li and Xiao Li continued until the sun and shadow were in the west, during which no one knew what they said, but after Li Er returned to the palace, he called Dugu Qingyun out and gave some orders, and then a new agency, the Intelligence Department, was born.

The newly formed Sixth and Seventh Groups under Li Chengqian were also all under the management of the Intelligence Section, and the scope and authority of the activities of the two groups were clearly defined.

The sixth group is mainly responsible for the collection and collation of overseas intelligence; The seventh group became an action group, and all the members were completely hidden, waiting for idleness.

Dugu Qingyun finally saw the 'Seventh Group' that left a deep impression on him, and the team of more than thirty people seemed very scattered, like a group of unknown squires in a meeting. No matter how you look at it, no one can see in these people that they are spies.

"Uncle Qingyun, they are the 'seventh group', I hope I didn't disappoint my uncle." Standing beside Dugu Qingyun, Li Chengqian said with a smile.

"His Royal Highness the Crown Prince said that it was too late for the minister to be happy."

Although Dugu Qingyun had suffered a loss in the hands of the 'Seventh Group', he thought that he would soon be able to have an equally powerful team under his command, and it seemed that the little face he lost in the Yingbin Building the day before yesterday was nothing.

"Since the uncle is satisfied, then the palace will go first." Li Chengqian doesn't need to worry about handover and other affairs, so there is no difference between him and his absence.

"Greetings to Your Highness." This time, Dugu Qingyun was very polite, without a trace of disrespect.

Li Er had already told him very clearly what happened the day before yesterday, and Dugu Qingyun finally remembered the fact that Li Chengqian almost hung up because of the mistakes of his subordinates.

In view of his own mistakes, Dugu Qingyun chose to be 'generous' to forgive Li Chengqian's revenge.

"Chenghu, do you know where Tang Jian lives?" Coming out of the intelligence section and standing in the courtyard of the military headquarters, Li Chengqian remembered Tang Jian, who was about to send an envoy to the Turks.

"I know which square it is, but I don't know the specific location." Wang Chenghu replied innocently, but his eyes were full of envy when he looked back at the courtyard of the Intelligence Division.

Kuroko now has an official position from the sixth grade, and he wants to surpass himself soon, but he is stupid, and he really doesn't have that blessing, if he takes the position of Kuroko, I'm afraid that he may kill many people at that time.

With all kinds of thoughts slowly turning in his head, he followed Li Chengqian step by step out of the yamen of the military department: "Your Highness, will you go to Tang Jian's house now?" ”

"Yes, go now, it's too late." Li Chengqian nodded, and got into the four-wheeled two-wheel drive (two-horse carriage?!) parked outside. Big carriage.

The original carriage was too broken, and it was finally overwhelmed some time ago and fell apart directly, so Li Chengqian had to drag his luxurious carriage out to make an envoy.

The reason why it is luxurious is because the new carriage has been completely remodeled during this time, the whole vehicle adopts a non-load-bearing structure, the carriage and the chassis can be completely separated, and the connection between the carriage and the frame are padded with cow tendon rubber pads to play a role in shock absorption.

A set of three leaf springs were added to each of the four wheels of the carriage, which were also used to reduce the vibration of the body.

The leaf spring is connected with the body by lifting lugs, and when necessary, the height between the body and the ground can be increased or decreased by changing the long or short lifting lugs, so as to improve the passability and comfort.

There is even a horizontal tie rod between the two wheels that are side by side, which is used to balance the body, so that the carriage can reduce the chance of rolling over when turning.

It can be said that all the technologies on the chassis of modern automobiles, as long as they can be realized, are all installed in this carriage.

It's just that the modified carriage is once again in tatters, except for one more horse pulling the carriage, it looks even worse than the previous one.

"Chenghu, when you go back in a while, you will be a prisoner, and remove the leaf spring below one more." Li Chengqian miscalculated the strength of the leaf springs, so that the carriage with three springs had almost no shock absorption effect at all.

"It's already very good, Your Highness, our car was much stronger before." Wang Chenghu was relatively easy to satisfy, and did not think that the current modified carriage was so bumpy.

"You know the, the recovery speed of this special steel plate after the transformation is really slow, and it has no effect on the continuous bumps at all." Li Chengqian muttered quietly, and only after personal experience did he know why leaf springs were only used in trucks in later generations.

A familiar chirping sound came from the roof ......of the carriage into the carriage, once again arousing Li Chengqian's thoughts about the future generations.

It was the cry of a pigeon, which Li Chengqian had raised a lot in later generations, and even the carrier pigeons he raised had won a ranking in the county's release competition.

However, he has not heard of it in Datang for more than two years, or he has never heard or seen a creature like a pigeon in Datang, which made Li Chengqian wonder if Datang does not have a pigeon as a creature.

Lift the curtain of the carriage and peek through the cart to the roof.

Sure enough, a snow-white pigeon was standing on the roof of the car, and at this time, Li Chengqian came out and tilted his head to look at him seriously.

After looking at each other for a while, the snow-white pigeon seemed to notice the trace of malice flashing in Li Chengqian's eyes, and 'fluttered' to shake off its wings and fly directly.

"Lao Wang, did you see that bird?" The pigeon flew away, and Li Chengqian was suddenly in a hurry, and kicked Wang Chenghu's buttocks.

"What, what bird?" Wang Chenghu was stunned for a moment, turned his head to look at Li Chengqian and asked.

"Look what Lao Tzu is doing, in heaven." Li Chengqian grabbed Wang Chenghu's head and turned to the direction of the pigeon in the sky.

"Oh, I see. Your Highness likes? Wang Chenghu glanced at the pigeon, lowered his head and continued to look at the road, and asked.

"Stop right away and keep up with the bird." Looking at the careless Wang Chenghu, Li Chengqian's teeth itched with hatred, and he wanted to bite him to death.

Li Chengqian didn't know how the pigeon appeared, and he didn't know who raised it, but since he saw it, he never let it go.

In this era when communication basically relies on roaring, it is unpredictable how important a pigeon is, this time Li Chengqian made up his mind, if he found the owner of the pigeon, he would just do it, if he couldn't find it, then he would transfer the left and right guards to seal Chang'an City.

"Your Highness, what are you chasing it for, it's flying in the sky, we can't keep up." Wang Chenghu stopped the carriage, stared in the direction of the pigeon's circle, and muttered.

"Why are you talking so much nonsense, hurry up, if you can't catch you, go back and pack your things, and go to guard the city gate tomorrow." Li Chengqian's mind is now occupied by the word carrier pigeon, who cares about the sky and the earth, just urging Wang Chenghu to catch birds.
