Until he returned to Lujiazhuang, Lu Chen didn't figure out what kind of mount he could find for Feng Huai, but Lu Chen was still going to find Li Shimin to get his "Zhaoling Six Horses" to try for Feng Huai, he had helped the eldest grandson Wujian control the "qi disease", Li Shimin wouldn't give him face for such a thing, right?

Besides, not only does the future Empress Changsun need to control her "qi disease", but the princess Changle, who is known as "a collection of thousands of favors", also needs this medicine, although Her Royal Highness the princess is only two years old now.

What Lu Chen planned in his heart, Liu Jing and Feng Huai naturally didn't know, but after entering the study, Feng Huai stayed outside the door, Lu Chen took a sip of tea first, and then put down the teacup and greeted Liu Jing in front of him.

"Go back, you go and pick a few clever leaders in the back guards, and then let them bring about ten back guards, all of them are placed in those dart games, carrier pigeons, one bright and one dark, and the rest don't need to be taught to you by this father, right?" Lu Chen told Liu Jing these words, and then looked at Liu Jing.

"Grandpa, don't worry, I know what to do!" has been by Lu Chen's side for so long, don't look at Liu Jing's age, but he is no longer the hairy boy in the blacksmith workshop, he has seen the emperor who others have never seen in his life, he has seen it several times, plus the "edification" by Lu Chen's side, and he also understands this kind of thing.

"It's good to know! I'll leave this matter to you! Lu Chen nodded, and didn't say much, this dart game can be said to be for Liu Jing's training, as for if something really goes wrong, Lu Chen naturally has a way to give him a cover.

"Yes!" Since his father-in-law handed over this matter to himself, Liu Jing naturally wants to handle this matter neatly, Liu Jing is too familiar with the old Beiwei to be familiar with it, who to send to take someone, Liu Jing already has a trace of intention in his heart, Liu Jing withdrew from the study, and went straight to the Beiweiwei camp.

Not long after Liu Jing left, when Lu Chen was looking at the map, he heard someone knock on the door of the study.

"What?" Lu Chen asked directly.

"Grandpa, Commander Su is here!" Feng Huaiying, who was guarding the door, said.

"Come in!" Lu Chen answered directly, followed by Su Dingfang's opening of the door of the study, and walked in quickly.

Looking at Su Dingfang's anxious look, Lu Chen sat on the chair and looked at Su Dingfang and asked, "Why are you in such a hurry?" ”

"Grandpa! Received a pigeon book! After Su Dingfang saluted Lu Chen, he directly took out a small bamboo tube from his belt and presented it to Lu Chen.

"Huh?!" Lu Chen, who originally wanted to pick up the tea cup and take a sip of tea, directly gave up this idea when he heard Su Dingfang's words, reached out and took the small bamboo tube that Su Dingfang handed to him, opened the bamboo tube and took out a roll of paper directly from it, and then looked at it.

"Huh! This is Lao Meng's news! After reading the contents of the note, Lu Chen laughed directly, and then handed the note to Su Dingfang.

Su Dingfang took it and took a look, and there were only twelve words on the note: "I have arrived in Yingzhou, everything is fine, don't read it!" ”

"It seems that Lao Meng is about to arrive in Danyang!" Seeing the word "Yingzhou" on the note, Su Dingfang also laughed, after all, he had just received the flying pigeon pass back, this was the first time he received the flying pigeon pass, Su Dingfang did not dare to delay, so he hurriedly came to find his grandfather, and now seeing the content of the passenger, Su Dingfang also secretly admired his own father in his heart, this way of transmitting the message is much easier to use than those post stations.

"Write back to him!" Lu Chen said directly to Su Dingfang.

"Don't know how to reply?" Su Dingfang looked at Lu Chen and asked.

"Do what you do, be careful!" Lu Chen's fingers tapped on the table a few times, and after pondering for a while, he directly said eight words to Su Dingfang.

"Yes! Subordinates will do it! After Su Dingfang nodded in response, he withdrew from the study, while Lu Chen continued to look at the map.

This Yingzhou is not close to Chang'an, it seems that Meng Ji and his subordinates should take the waterway, after all, "eight rivers around Chang'an", Meng Ji's gang can get to Yingzhou so quickly, they should take the road of Yinghe.

According to the day, the next time the flying pigeon comes back, it should be the time for Meng Ji and them to go to Danyang.

Historically, the rebellion between Fu Gong Yi and Zuo Youxian was in August of this year, and now Meng Ji has led people to Yingzhou, and there is still about half a year before Fu Gong Yi pretends to use Du Fuwei's letter to seize the military power of Wang Xiong's birthday, and this time should be enough for Meng Ji to complete the plan.

Lu Chen put away the map, then leaned back in his chair and tapped on the table in thought.

Just when Lu Chen was thinking about what loopholes were still in Meng Ji's plan, there was a knock on the door of the study again.

"Who?" Lu Chen, who was disturbed and pondering, asked directly in a deep voice.

"Grandpa, someone sent a letter!" This time, the voice was Su Chang's.

"Come in!" After Lu Chen said something in a deep voice, Su Chang directly pushed the door and walked in.

"Whose letter came?" Looking at the letter in Su Chang's hand, Lu Chen directly raised his eyebrows slightly and asked.

After Su Chang gave Lu Chen a gift, he replied: "Grandpa Hui, he is a person dressed as a small man, and after coming to Zhuangkou and handing over the letter to Commander Lian, he left!" Su Chang said and presented the letter to Lu Chen.

"Guy?" Hearing Su Chang's words, Lu Chen frowned slightly, but still reached out to take the "letter" that Su Chang presented to him.

The letters of this era did not have the kraft paper envelope of later generations, and the so-called envelope of this era was a folded letter sandwiched between two pieces of thick cocoon paper, and the carp pattern was painted on both thick cocoon papers, so the letters of this era were also called "double carp", and the double carp was tied with a fine hemp rope cross.

There is a fire paint seal on the knot of the hemp rope, but there is no such thing as a seal, just a simple fire paint seal with a feather.

Lu Chen weighed the "letter", and at the same time observed it with the knot, and confirmed that there was no problem, so he knocked off the fire paint, opened the "double carp", and opened the letter sandwiched in the middle to look at it.

"Huh! I didn't expect these guys to be really tempted! Looking at the contents of the letter, Lu Chen laughed directly, and he was extremely happy when he smiled.

Seeing that Lu Chen was so happy after seeing the content of the letter, Su Chang consciously withdrew from the study.

"Looks like this is the right move!" Lu Chen threw the letter and the "double carp" directly into the iron furnace, watching the letter and the "double carp" burned in the iron furnace, Lu Chen said to himself, and Lu Chen's handsome face that was directly reflected by the flame flickered, "This is also a good opportunity to test those dart games!" Looking at the burned letters and "double carp", Lu Chen smiled slightly.
