"I can go with you, but I have to take my sister with me." Yang Tian said almost without thinking about it.

"No problem, it's your business to take whomever you want." Li Chengqian shrugged, turned back to Cheng Huaan and asked, "Have you done it?" We're leaving. ”

At the end of the day, in the Intelligence Section of the Ministry of War, Li Chengqian sat in Dugu Qingyun's office for a long time: "Uncle Qingyun, I can leave the person to you, don't give me practice." ”

"Your Royal Highness the Prince, what do you mean? That kid is past the age of martial arts, and he can't practice no matter how he practices. Dugu Qingyun frowned and said.

"Do your best, I'll be of great use to this kid in the future." Li Chengqian's mystery is that he refuses to tell the truth, but just asks Dugu Qingyun to train people according to the requirements.

"Alright then, do your best." Li Chengqian refused to say, and Lao Dugu naturally had no way to ask more, so he could only reluctantly agree to his request.

Leaving the Intelligence Department and sending Wang Chenghu to send the carriage back, Li Chengqian walked to the palace alone.

Yang Tian's matter was an accident, but it was also this accident that prompted Li Chengqian to have some new ideas.

He planned to send Yang Tian to the Kingdom of Wu to completely mess up the country, but before that, he must be well trained, including the use of special equipment, the secret language of the intelligence department, the study of the Chinese language, navigation skills and a series of training and training.

When these things are learned and mastered, it will be time for Yang Tian to go to sea, and then he will lead his group to operate in the territory of the Wa Kingdom, and the main tasks are: drawing maps, detecting minerals, and buying and inciting the nobles and commoners of the Wa Kingdom.

Of course, all this was Li Chengqian's idea, and in his plan, it would take several years to study in the early stage, and as for the Japanese country, it might take several years to prepare, and so on.

In short, Yang Tian's task could not be completed in ten years, and if his sister was not in his hands, Li Chengqian would never rest assured that he would be sent to the Wa Kingdom.

In this way, Li Chengqian walked back while thinking about his thoughts, and when he arrived at the 'Lanruo Temple', he basically figured everything out.

Although I always feel that it is disgraceful to use family affection to trap a person, but because the plan is even bigger, it can only be like this, at most, I will make up for that Yang Tian in the future, or find a good family for his sister to marry.

For example, Li Chengqian thinks that Lao Xue is a good person, and he is a good match with Yang Tian's sister, and the age difference is not much, only five years old. After a few years, before Yang Tian was ready to cross to the east of the Japanese Kingdom, he could just catch up with the wedding of his sister and Lao Xue.

In this way, Yang Tian does not lose, his sister does not lose, Lao Xue does not seem to lose, he is mixed in the military camp every day, God knows which year a girl will take a fancy to him.

The night was spent in calculations and pondering, and when the light was shining the next day, the great crown prince once again got up early and quietly slipped out of the palace.

The time is about to reach the Shangyuan Festival, so you have to hurry up and do anything, otherwise once you miss the Great Dynasty Meeting, you will be bounced down by the royal history who like to hear the wind and do things, and it is likely to delay a lot of things.

"Your Highness, what do those Khitan barbarians have to say, why don't we go back." Originally, some of the strong people around Li Chengqian had something to do, and only Wang Chenghu was left with some leave, so as soon as Li Chengqian mentioned Khitan, this fool immediately looked a little nervous.

"If you don't understand, shut your mouth to this palace, don't talk too much and make people laugh." Li Chengqian gently lifted Wang Chenghu in the back, anyway, he had rough skin and thick flesh, and he didn't feel anything when he kicked it.

There was not much time, and when the car arrived at the post house, Li Chengqian walked in under the greeting of the post house.

"Brother Khitan Qu Shuai, I have seen His Royal Highness the Prince of the Tang Dynasty." A young man in his 20s, dressed in a fur coat, bowed slightly and performed some unique etiquette of the Khitan people after seeing Li Chengqian.

"You're Brother Cave?" Li Chengqian looked at the sturdy young man in front of him with some surprise, but he didn't expect the future Song Desert Governor to be so young now.

"The minister is exact, His Highness knows about me?" Brother Cave was stunned for a moment, as if he didn't expect Li Chengqian to know about him.

"Brother Dahe Cave of Khitan, brave and good at fighting, intelligent, and brave with 10,000 invincible ......" After knowing that the young man in front of him was Brother Dahe Cave, Li Chengqian had a lot more confidence in the plan he thought of last night, and he couldn't help but praise Brother Cave a few words under excitement.

Before the results were halfway through, the future Khitan lord, the Governor of Songmo, was already flushed, and he didn't even dare to say: "Your Highness, Brother Gu really doesn't dare to praise His Highness like this." ”

Li Chengqian also realized that his words seemed to be a little too much, and after holding back the words, he muttered slightly: "I can't hide it, this time I came to the palace because I wanted to ask you for help." ”

"Your Highness, please speak, as long as the foreign minister can do it, he will never shirk." When Brother Cave saw what Li Chengqian said formally, he also put away his smile at the moment.

"Okay, the Khitan warriors are really happy, and the palace is welcome." Li Chengqian pretended to be heroic and patted the case next to him: "I don't know if the Khitan warriors can do human business?" ”

"Population business?" Brother Cave scratched his head and asked a little puzzled.

"If this palace wants to buy some slaves, it's better to be obedient, I don't know if Brother Cave has any suggestions?" In order to avoid some embarrassing problems, Li Chengqian was very humble.

"Obedient." Brother Cave smacked his lips: "Then there are only Goguryeo slaves, those people are very obedient and work very hard." ”

Although he didn't know why the prince of a dignified country wanted to buy slaves, Brother Cave still decided to follow the advice of the chief of the Mohui and try to cooperate as much as possible.

"So how much does a Goguryeo slave cave brother think is the right price?" Since the issue of slaves has been discussed, Li Chengqian did not hide it, and bluntly asked about the price of the cave brothers.

At this time, the Tang Dynasty did not actually prohibit the slave trade, and Turkic slaves, Western Regions slaves, and Kunlun slaves were all very common in the tooth shop.

But there was very little to buy and sell in large quantities, because the slaves had to be eaten, and when there was not a great deal of work for them, it was a mere loss of money to keep them.

"How many slaves does Your Highness need?" In the concept of Brother Cave, Li Chengqian probably just wanted to buy a few slaves to play with, so he planned to give him a batch if there were one hundred and eighty.

But Li Chengqian's next words startled him: "You just have to catch, how much you have, how much the palace wants, but the price must be appropriate." ”

How much do you want, this is a big business, Brother Cave's palms were a little sweaty, and after rubbing his hands vigorously, he said tentatively: "A pound of salt is a male strong laborer, what does Your Highness think?" ”
