Datang: The prince of salted fish was overheard by Li Er

Since Qu Tutong handed over the Ministry of Industry to Duan Lun, he voluntarily requested to guard Luoyang.

However, not long ago, news of Qu Tutong's serious illness came from Luoyang, and there was also a letter from Qu Tutong, hoping that Li Shimin could choose the successor of the Luoyang governor.

Li Shimin who received the news naturally sent an imperial doctor to Luoyang to see Qu Tutong.

Li You, who received the news, suddenly went to the court, expressing his admiration for the prestige of Mr. Qu Tu, and the Shence Mansion Medical College also sent people to Luoyang for diagnosis and treatment.

Li Shimin naturally knew that Li You had been annoyed a lot recently, so he nodded his approval.

So after Li You came back, he asked Xiaoying and the others to clean up.

And Wei Zheng, who knew everything, also ran over to dissuade him after he went to court.

"King Yan, to be honest, you may not dare to go too far in Chang'an due to the influence of these aristocratic families, but it's hard to say when you arrive in Luoyang."

"It's the territory of the Zheng family in Xingyang, I'm afraid your every move is under their noses."

Li You was unmoved after hearing this, instead he smiled and said, "Master Wei, who told you that this king is going to Luoyang?"

Wei Zheng immediately rolled his eyes at him, and said as if you don't lie to me: "Today in the court, King Yan took the initiative to petition to treat Jiang Guogong. Is it true that this matter is true?"

Li You laughed again and said, "This king said that the medical school will treat Jiang Guogong, but I didn't say that I want to go by myself?"

"Of course we have to go to the medical treatment, but it's Dr. Duanmu who brings the people from the medical school."

"My lord, the place I'm going to is Mount Zhongnan!"

This time, under everyone's noses, Li You was planning to make a plan to repair the plank road and cross the old warehouse secretly.

Mingli was heading towards Luoyang with great fanfare, but secretly he was preparing to go to Zhongnan Mountain with Sun Simiao.

After explaining the plan, Li You said slyly again: "You are the only one who knows about Mr. Wei. If anyone finds Zhongnan Mountain by then, it will be your big mouth."

Hearing this, Wei Zheng hurriedly prepared to swear to keep it a secret, but Li You laughed, "Your Majesty Wei, you don't have to do that, this king trusts you."

This time the preparations went on for two full days, and on the third day Li You set off with a mighty force.

After the main force left Chang'an City for ten miles, four figures quietly left the main force.

These four people are Li You, Xiao Ying, Sun Simiao and Zhou Huai'an.

Naturally, Sun Simiao was still dressed as You Fang Langzhong, Li You and Xiao Ying were dressed as medicine boys, and Zhou Huaian was dressed as the accompanying porter.

Originally, Li You didn't want Zhou Huai'an to follow, so one more person would be more dangerous to be exposed.

However, Xiao Ying insisted on this, saying that there was no one with strong martial arts to guard her, so she immediately told Concubine Yin about this matter.

Li You had no choice but to choose Zhou Huai'an, who was a master of martial arts but not so conspicuous in the Shence Mansion, to accompany him.

In order to avoid possible eyeliners, the four of Li You got into the forest after leaving the avenue.

Walking in the forest was no problem for Sun Simiao, who used to gather herbs in the mountains, and it was not difficult for Zhou Huaian, who was a martial arts practitioner, and Li You, who had been strengthened by the system.

But it was the accompanying Sakura who suffered.

However, Xiao Ying has a stubborn personality, and she didn't say anything when she saw Li You, but she gritted her teeth and followed the rhythm of the three of them.

After walking like this for a day, when the four of them rested in a dilapidated mountain temple at night, many blisters appeared on Sakura's feet.

"Miss Sakura, are you alright?"

Li You had already discovered what was wrong with Sakura, but because of Sakura's persistence, he couldn't say anything in front of the other two.

Now that everyone was resting, Li You asked with concern.

"My lord, I'm fine!"

"Also, now that the lord is grown up, it's fine to just call the slave girl Sakura."

"If you call it like before, it will damage the majesty of the prince, and Sakura is also sincere and fearful."

In fact, Xiao Ying had thought about this matter for a long time. Li You called her Miss Xiao Ying because of the habit in Concubine Yin's Palace.

At that time, Li You was playful, and Concubine Yin asked Xiao Ying to discipline him severely.

In order to prevent Xiao Ying from violating the palace rules, Concubine Yin privately announced that she would accept Xiao Ying as a foster daughter and asked Li You to call her sister.

Later, although the ceremony of adopting the adopted daughter was never carried out, Li You's address was settled.

Hearing this, Li You said indifferently, "Miss Xiaoying, don't worry, this is all due to the concubine mother."

"After we go back this time, I will remind Concubine Mother to let her complete the ceremony."

"Back then, this matter was out of fear of trouble at Zongzheng Temple, but now this king and Grandpa Zongzheng have settled their suspicions, so it's not just a matter of one sentence."

However, Li You didn't expect that after he finished speaking, Xiao Ying quickly waved his hands and said, "No, my lord, absolutely not."

"The story of righteous daughter is an expedient measure for Concubine Yin. Now, once it is reported to Zongzheng Temple, no matter what the result is, this servant of King Yan's Mansion will not be able to stay no matter what."

"This slave is deeply favored by Concubine Yin and the prince, and has already vowed to repay the prince for the rest of her life."

Having said this, Sakura couldn't help but blushed and lowered her head.

At this moment, Li You re-examined this girl who was almost inseparable from him since childhood.

He found that Sakura, against the background of the bonfire, had an indescribable charm on her red face.

Li You couldn't help swallowing subconsciously.

Although he is only nine years old on the outside, he is a grown man inside.

In the modern era of information explosion, at this age, we already know what we should know, and we gradually understand what we shouldn't know.

Suddenly Li You had such a slight impulse.

However, this impulse didn't last long, and Sakura, who noticed something strange, raised her head and asked, "My lord, what's wrong with you, is there something uncomfortable?"

Li You quickly came back to his senses, and while cursing himself inwardly, he said, "Miss Xiao Ying... Xiao Ying, your foot is hurt, you better not be so brave tomorrow."

"We're not in a hurry, why don't we find a village and live there for a few days before talking about it."

Then, in order to divert the topic of Sakura, Li You complained again: "Hey, the current infrastructure of Datang is still too poor."

"This time out of the city, even the officialdom is so unbearable."

"Slightly remote mountain villages don't even have official roads."

"As the saying goes, if you want to get rich, build roads first. If the roads are not repaired, how can Datang's economy be strong?"

"When the matter is over this time, I must vigorously build roads, not to mention replacing them all with cement roads, at least complete the official roads for every village."

Li You's words successfully attracted Sakura's attention.

She nodded and said, "Concrete road?"

"My lord, you really dare to say it."

"Although this cement workshop belongs to the prince, isn't it too extravagant to use it to build roads!"

"Besides, there are ruts on the current roads. If cement is used to repair them, how can the ruts be pressed out in such a hard place!"

The ruts that Sakura refers to are the wheel marks on the road.

You must know that the roads in this era are basically dirt roads. The big problem with dirt roads is that the roadbed is too soft.

After driving for a long time, two deep grooves will form, which are the ruts that Sakura mentioned.

After Qin Shihuang unified the Central Plains, he proposed that the cars be on the same track, which is to make the width of the ruts in various places the same.

In this way, everyone's cars move in the same rut, so that all the cars can run smoothly, and can significantly reduce animal power consumption and axle wear.

Regarding Xiaoying's question, Li You smiled again: "All the roads here have become hard ground, and the carriage can run as it wants, so why use ruts!"
