After seven years of fiefdom, Li Shimin asked me to return and become the crown prince.

"Yaojin, aren't we looking for the secret of papermaking? Why are we heading to Lingnan?"

On the way to Lingnan, Li Daozong was very puzzled. When Li Shimin came, he just told him that Cheng Yaojin would explain it to him.

In a wild place like Lingnan, is there a new papermaking technique?

He didn't believe it.

"Haha... Your Highness's impression of Lingnan is still stuck in seven years ago!" Cheng Yaojin laughed, and then asked cautiously:"Do you know Wanbao Pavilion?"

"Wanbao Pavilion? I also bought wine and tea there...."Li Dao Zong started drooling at the thought of wine.

I have to say!

The wine and tea in Wanbao Pavilion are really good.

Cheng Yaojin smiled mysteriously:"Hehe... these things are all from Lingnan!"

"Lingnan...Impossible, I asked the guys at Wanbao Pavilion, and they all said it was from the country west of the Western Regions!"Li Dao Zong shook his head. In his impression, Lingnan was a wild and barbaric place. How could there be so many strange things?

If there really were, then why would Lingnan be called a barbaric place?

"They lied to you!" Cheng Yaojin replied with a smile.

Li Daozong:"But I passed by Lingnan once ten years ago, and it was also full of miasma...."

"That was in the past, because you have such a good nephew!" Cheng Yaojin laughed. He highly respected Li Kuan.

""Good nephew, are you talking about Chengqian?" Li Daozong still didn't understand what Cheng Yaojin said, and continued to ask in confusion.

That's right!

In Li Daozong's memory, someone was talking about his nephew, that is Li Chengqian, the current prince.

"It's not him!" Cheng Yaojin shook his head.

"Who is that? Lingnan...Could it be Kuan'er?" Li Daozong couldn't believe it. If Cheng Yaojin hadn't mentioned Lingnan, he probably wouldn't have remembered Li Kuan. He couldn't help but sigh:"It's been a few years, and I don't know how Kuan'er is doing?"

Speaking of Li Kuan, he was a child with a miserable life. He was driven out of Chang'an City early, and no one knew how he was doing in Lingnan, whether he suffered or not.

"You don't have to worry about him, that guy knows how to enjoy life better than you and me!" Cheng Yaojin shook his head, looked at Li Daozon's puzzled eyes, and continued:"You will know all this when you arrive in Lingnan, but there is one thing, when you arrive in Lingnan, don't reveal your true identity, just say that you are an official businessman, and listen to me for the rest!"

Cheng Yaojin didn't say too much to Li Daozon, because some things need to be seen with his own eyes to be considered true, otherwise, he will definitely think you are lying.

Just like before he came to Lingnan, if someone talked about the current situation in Lingnan, he would not believe it.

Without Li Shimin, the carriage drove very fast this time, and it took less than eight days to reach Lingnan.

""It's so flat. What is this road made of? It looks harder than stone!" Entering Lingnan, the first thing that caught his eye was this wide road.

Straight and flat!

The carriage drove on it without feeling any bumps.

Moreover, he saw that Lingnan was not a barren land. The rice fields that came into view were lush and green.

There were also many carriages of merchants on the road....Is this really Lingnan? If it is Guanzhong, he would believe it.

"You don't know, this road is called cement road, it is a new type of material! And the rice fields on both sides of the road have two crops of rice...."

Cheng Yaojin looked at Li Daozon's stunned and complacent look.

You must be shocked, right? I was also like this when I first came here. There will be more surprises later.

One afternoon later...

Li Daozon saw the towering city wall, his mouth opened wide:"This... is this Lingnan City?"

After seeing the city, he was completely shocked.

From the outside, it was Chang'an City, so magnificent.

Outside, there were people doing business, and the aroma of food from the stalls made him swallow his saliva.

He had never eaten such food before.

"Stop, the rest of the caravan stay outside!"After the carriage arrived at the city gate, it was stopped by the guards guarding the city as usual.

Cheng Yaojin was already familiar with this process. Besides, the guards who came with them were the same ones who came with the last tour. With a glance, they all obediently went to the place where passers-by lived nearby.

"What does this mean?" Li Daozon wanted to say something, but was pulled into the city by Cheng Yaojin.

As they walked, Cheng Yaojin introduced to Li Daozon:"This is the rule of Lingnan City, just get used to it!"

"Yaojin, have you been here before?" Li Daozong finally came to his senses and asked Cheng Yaojin.

"Yes, Your Majesty and I came here once more than a month ago. Lingnan has changed a lot in these years!"Cheng Yaojin pulled Li Daozon to sit in front of a small stall. He could not forget the braised pork here. He also tried to make it at home, but the taste was completely different:"Let's eat first, I'll tell you slowly...."

At this time, Cheng Yaojin told Li Daozong about his last experience.

Li Daozong was also very sad. Just as Cheng Yaojin said, if he had not really seen Lingnan City, it would be impossible to believe what Cheng Yaojin said.

While he was talking, the braised pork came up, and he subconsciously picked up a piece:"Hiss~~This meat is too fragrant, what kind of meat?"

"pork!"

"How can pork be cooked so deliciously?"

After having enough food and drink, they continued to head towards the city center. Lingnan City is now more prosperous than it was a month ago. Many businessmen have brought their families to Lingnan.

"Their windows are really made of glass!"

"....."

In Li Daozong's shock, Cheng Yaojin came to the inn where he stayed last time.

Now it was late, they planned to rest for a night and visit Li Kuan the next day.

""Mr. Cheng, you are here again?" The waiter recognized this generous guest.

Cheng Yaojin was not polite and threw him a tael of silver:"As usual,���A superior room!"

"Okay, please follow me!"
