At this time, Li Er also felt a little strange. After all, although the official roads of the Tang Dynasty were flat, the academy was built in the mountains, so it was certain that the bumps were bumpy. However, Li Er, who was sitting on the carriage, did not feel any bumps at all, so Li Er also curiously pointed his face outside the carriage.

As a result, Li Er saw a flat and straight gray cement road leading straight into the mountains.

"Here, Guanyin maid, come and see what paved this road is made of." After Li Er said that, he let out the window beside him. Empress Changsun tilted over her body and looked at the road under her feet. As a result, Empress Changsun shook her head and said, "I don't know what paved this road is made of."

"Stop." Li Er couldn't help but feel curious, so he asked the driver's escort to stop the carriage that was running on the cement road. After the carriage stopped, Li Er quickly walked out of the car.

Li Er stood on the cement road and did nothing else. He just stomped his feet hard and found that the road surface was much harder than he thought. So Li Er bent down and started to buckle the ground with his hands. Li Er, who was sticking his butt, looked very indecent.

But Li Er locked it up for a long time, let alone the stones, and even the soil was not deducted. Li Eryi got nothing except the dust on his hands.

"Come here, get some water for me." Li Er ordered.

Soon Li Er's guard took a water bag. Li Er took it and sprinkled all the water in the entire water bag on the ground. Li Er thought that the road would become muddy like a dirt road, but what Li Er never expected was that the water was poured on the road, but the road was nothing unusual. Not to mention mud, even the dust was washed away cleanly.

"Hey, this road is really famous." Li Er couldn't help but make a questioning voice.

"Erlang, what are you doing? Why haven't you come back yet?" Empress Changsun, who was sitting on the carriage, didn't know what Li Er did on the road, so she asked in the carriage.

When Li Er heard the urging of Empress Changsun, he stopped lingering on the road and got on the carriage. Li Er got on the carriage, and the carriage slowly continued to move towards the academy along the hard cement road.

"Erlang, what did you do just got out of the car?" Queen Changsun continued to ask.

"Ah, I just went down to see what the road is made of and why it is so hard and flat." Li Er replied truthfully.

"Then father, do you know what this road is made of?" Li Lizhi also turned her face and asked.

When Li Er heard his daughter's question, he couldn't help but feel a little embarrassed. After all, his wife and daughter asked him, but he didn't know the answer, but he didn't know, so Li Er had to tell the truth: "Well, I don't know, but this thing must be made by that guy Qingquan. Just meet Qingquan and ask him later."

After hearing this, Empress Changsun nodded: "Yes, this kind of thing can only be made by Qingquan. After all, Qingquan can always bring out some surprising things."

After hearing Zhang Nan's name, Li Lizhi didn't know why, but her heartbeat was so fast that it was a few beats. Li Lizhi wanted to ask about the details, but for some reason, Li Lizhi couldn't speak. After all, Li Lizhi had never even said anything to Zhang Nan.

The last time we met, Zhang Nan led his troops to defeat the Turks and captured Jiliban's army and returned to the court at the celebration banquet. The song "The Legend of the Knights" written by Zhang Nan was deeply remembered by Li Lizhi.

Although Li Er did not notice it, Empress Changsun saw his daughter's appearance, which was still absent. However, Empress Changsun did not make it clear, but just pursed her lips and smiled faintly.

The carriage was running on the concrete road. Soon, the carriage slowly stopped at the entrance of the academy, but Li Er, who was sitting on the carriage, didn't know. When he felt the carriage stop, Li Er sat in the carriage and asked, "What's wrong? What's wrong? Why did you stop?"

The sound of Qianniuwei driving came from outside the carriage.

"Report to the emperor, the academy has arrived."

"Oh? It's already here? Why is it so fast? I remember that this academy is not far from Chang'an City." Li Er glanced at Queen Changsun in surprise, but Li Er still got out of the car.

After Li Er, Empress Changsun and Li Lizhi got out of the car, Li Er discovered that Li Yuan was standing not far from the carriage.

"Erlang is really a big air. I have been standing here for so long. I won't get off the car quickly when the car is here. I don't know what I'm doing when I sit in the car." Li Yuan said with some displeasure. After all, this is the first time I'm waiting for my son.

Li Er also realized the displeasure in Li Yuan's mouth, and quickly pulled Queen Changsun and Li Lizhi to Li Er's side to salute Li Yuan.

"Forgive me, Father, but this journey is indeed a bit beyond my expectations. This journey seems to be much shorter." Li Er said hurriedly.

"Hmph, this road is not much shorter, it is paved well, so you can come so quickly. Do you know that the road I stepped on was paved by me personally." When he said this, Li Yuan stomped his feet proudly, as if he was showing off, letting Li Er see how strong the road he paved was.

"Father, how can you work yourself? This is really too..." Li Er didn't know what to say for a moment, after all, Li Er dared not accuse Li Yuan of not wanting to say anything.

"What's so wrong? As the Supreme Emperor, I naturally have to set an example for the world. I have also participated in this journey. It's not to tell Erlang that sometimes, for those who are the king, you have to personally experience the sufferings." Li Yuan looked like a loyal elder, and Li Er had to listen if he didn't listen.

Li Er had to nod and said, "Yes, yes, yes, my son has received the teachings."

"Well, this is almost the same. Let's go and enter the academy." Li Yuan said, then turned around and prepared to leave.

"Hey, Father, wait, this, Qingquan?" Li Er looked around, but did not see Zhang Nan at the gate of the academy, so he became a little strange. After all, he had come to the academy in person, so Zhang Nan did not come out to greet him. It was really rude.

"Hmm? What, you are still a little dissatisfied with me here to receive you in person?" Li Yuan asked strangely.

"Ah, no, it's just a little strange if I didn't see Qingquan." Li Er waved his hand and said.

"He is sorting out your office. Humph, Erlang, you are such a good method. You have such a loyal minister." Li Yuan said with a little dissatisfaction. It is probably because Li Yuan thought of why there was no minister like Zhang Nan when he was in power.
