"Aye, why are you so angry?" Xiao Rui, who had just passed through the front hall, heard the sound of the teacup breaking, as well as Xiao Yu's angry scolding, Xiao Rui walked in from the door, and at a glance saw the scattered teacup fragments on the ground, as well as the oil tea spreading everywhere.

"Why don't you clean up yet?!" Xiao Rui directly glanced at the servant girl who was a little trembling on the side, and said directly, the servant girl hurriedly cleaned up the debris, and at the same time took a rag to wipe the ground clean, and hurriedly exited the front hall, at this time there were only Xiao Rui and Xiao Yu father and son in the front hall.

"Those shit! How long has Lu Chen been away from Beijing, and now I found out! Xiao Yu still said a little angrily.

"Aye, why are you so atmospheric!" Hearing Xiao Yu's words, Xiao Rui smiled directly, "That Lu Chen is not in Chang'an now, but I heard that Princess Langya went to Lujiazhuang, what do you think of that Lujiazhuang?" Xiao Rui refilled Xiao Yu with a cup of tea, then sat on the chair on Xiao Yu's left hand side and asked with a smile.

"Son, you don't know! There is something in Lu Chen's hand, which is very harmful to our family! That thing stays in Lujiazhuang for a day, and you Aye and I will be restless for a day! Xiao Yu looked at Xiao Rui and said with a sigh.

"Oh? I don't know what it is? Xiao Rui looked at Xiao Yu and asked with some curiosity.

"The Art of Printing!" Xiao Yu looked at Xiao Rui and said in a low voice.

"The art of printing? Don't we have an engraving master at home? Can't we print it at home? Xiao Yu looked at Xiao Yu a little puzzled and asked.

"Son, the printing technique that Lu Chen made is much stronger than our engraving printing technique, then Lu Chen said that in one day, thousands of books can be printed, if it is released, not only our family, I am afraid that all the families will suffer a great disaster!" Xiao Yu didn't hide it from his eldest son, and directly told Xiao Rui what he saw in Changyuan Building that day.

"Now that Lu Chen has released the so-called 'refined salt', if he releases the printing technique again, I'm afraid everyone will collapse!" Xiao Yu sighed and said, the people sent to spy on the poisonous salt mine that day came back to report, and they didn't find out how Lu Chen eliminated the toxins in the poisonous salt mine, the only news that was useful was that they saw that those workshops that processed "poisonous salt" would always send some black things to the workshops one by one, but they didn't have the opportunity to get any "samples".

"This..."Hearing Xiao Yu's words, Xiao Rui also groaned, Xiao Rui knew that his words were not alarmist, the family can stand, one is the wealth in the hand, and the other is the reader's scroll, why the reader submits the scroll to the family, it is not because many books are in the hands of the family, you want to seek fame and participate in scientific examinations, books about this are basically in the hands of the family, which forces those who read to have to "take refuge" in the family, in order to have the opportunity to participate in the scientific examination and seek fame.

If Lu Chen directly put these books outside, how could the family gather "talents", without control, the roots of the family would be broken.

"However, now that Princess Langya is sitting in Lujiazhuang, and there are three guards in the East Palace leading troops to defend it, how can this be done?" Xiao Rui couldn't help frowning and looked at Xiao Yu.

"Aya, do you say that the prince's three guards are guarding the princess or guarding Lujiazhuang?" Xiao Rui seemed to think of something, and looked up at Xiao Yu directly.

"What's the difference?" Being asked by his son like this, Xiao Yu couldn't help but be stunned for a moment, looked at Xiao Rui and asked.

"As far as my son knows, although Princess Langya was given to Lu Chen by His Majesty, it seems that the three books and six ceremonies have not yet been completed, and now Princess Langya is not qualified to live in Lujiazhuang according to the etiquette law, right?" Xiao Rui looked at Xiao Yu and said with a light smile.

"Huh?!" Being reminded by Xiao Rui like this, Xiao Yu seemed to have thought of something, "However, Princess Langya can live in Lujiazhuang so blatantly, I'm afraid it will only be done with His Majesty's permission, right?" However, Xiao Yu immediately denied Xiao Rui's statement, after all, if Li Yuan did not allow it, how could Li Yanjun dare to take the three leading troops directly into Lujiazhuang with such fanfare.

"But, Aya, the three of them have become tigers, and all of them are gold! If there are many people who oppose it, I think Your Majesty will also consider the impact of this matter, right? If this matter is learned by everyone in the world, wouldn't it be a complete mess of etiquette? Xiao Rui added a cup of oil tea to himself, and after taking a sip, he still looked at Xiao Yu with a light smile and asked.

"You mean..."Xiao Yu naturally knew what Xiao Rui meant by this, this was to let himself take Zheng Shanguo, the secretary of the Ministry of Rites, and others to "force the palace" to Li Yuan!

"It's about everyone, and Aya still has to think about it carefully!" Xiao Rui got up directly, bowed to Xiao Yu, and then left the front hall, leaving Xiao Yu alone in the front hall.

"Grandpa, this is Xue Wanche's reply! There are also flying pigeons from home! The curtain was picked up by Lian Xiude, and when he came to Lu Chen, Lian Xiude took out a letter from Xue Wanche from his arms, as well as a bamboo tube containing news.

Lu Chen stretched out his hand to take it, not looking at the news sent from home first, but first reading Xue Wanche's reply, after reading it, Lu Chen nodded with satisfaction, "Pass the order, pull out the camp tomorrow, and the whole army will go north!" Lu Chen looked directly at Lian Xiude and ordered.

"Yes!" After Lian Xiude saluted directly, he turned around and walked out of the tent.

After Lian Xiude turned around and left, Lu Chen opened the bamboo tube and took out the note inside to read it.

"Looks like everything is still under control!" After reading the message sent by Liu Jing who stayed in Lujiazhuang, Lu Chen nodded with satisfaction, Liu Jing sent a flying pigeon biography this time to tell Lu Chen that Princess Li Yanjun of Langya took a team of three guards to stay in Lujiazhuang, but he also said one thing, that is, there have been more and more people peeping at Lujiazhuang recently.

"This Nizi is really powerful, I only dare to borrow two guards from Li Jiancheng, this Nizi directly went to Lujiazhuang with half of the troops of the East Palace with his brother!" After Lu Chen burned the note, when he thought that Li Yanjun had moved into Lujiazhuang with three guards, Lu Chen couldn't help but shake his head and smile, if Lu Chen knew that his future daughter-in-law wanted to turn Li Jiancheng into a bare pole, I am afraid that this Chang'an County official could laugh and go crazy directly.

Seeing that the note was burning, Lu Chen picked up a pen and wrote a note, and after writing it, he handed it to Feng Huai, asking him to hand it over to Su Dingfang and send it back to Lujiazhuang.
