"What did Gao Yang say?" Gu Qing asked in a low voice.

"You're still pretending to be confused for me?" Li Er looked at Gu Qing with disgust, "Boy, I tell you that although Gao Yang was not from Guanyin maid, he always regarded her as his daughter."

"I understand." Gu Qing nodded slightly.

"Let's go, I'm upset when I look at you."

Li Er issued the order to expel guests, so he had to leave the house. He walked out the door and saw Li Junxian sitting on the stone by the river. Gu Qing also sat down beside him and said, "What are you thinking?"

"I didn't think about anything, I just like to look at the village." Li Junxian said, looking at the village on the other side of the river.

"I lived here when I came to Chang'an. I grew up here and I am very familiar with it." Gu Qing said with his chin on his hands.

"I can't get tired of watching it, right?" Li Junxian said, "Every time I'm sunrise and sunset, I look at the village. In fact, the changes here are not big or small, and it's not small. Even this peaceful and peaceful scene is not tired of watching it. There is no hustle and bustle of Chang'an, nor the dilapidation of border towns. I now understand why His Majesty left the Daming Palace and came to this place."

Gu Qing turned around and looked at Xingzhai and whispered: "The purpose of his visit to this village is not just to see this village."

"Yes, Your Majesty is old and tired. It's great to spend his old age here." Li Junxian also said.

Li Shimin was not just for the sake of peace and prosperity. Gu Qing stood up and left Li Junxian. Li Er was able to stay in the village to watch himself and to suppress himself. Li Shimin knew very well that Li Chengqian could not control himself.

Looking up at the blue sky, Gu Qing sighed long. He had been to the Tang Dynasty for more than ten years. He had experienced a lot in the past ten years and understood a lot. Now he can never take a step out of the Chang'an territory in his entire life.

In fact, it is just a house arrest for yourself. You will be under house arrest for your whole life. Now you just can't leave Chang'an. Maybe you will be under house arrest for the rest of your life in the future. The world is like this. It's not good or bad. I admire Li Shimin in my heart. Li Shimin is also a hero. He will never indulge himself, and he can't rub the sand in his eyes. Sometimes I think about what does it have to do with him as long as the world is peaceful and some things have to do with him.

I have already owned all the power and power of the court, and even if I don’t want it, if I wait until I reach Li Er’s age, I would rather stay in this village and not go out at all.

Fan Jian was talking to several villagers while talking to him, and when he saw Gu Qing coming out, he hurriedly followed him.

"What are you talking about with them?" Gu Qing asked Fan Jian.

"The people in the village want to bring the fruits and vegetables at home, but the villain refused." Fan Jian returned with a smile and said.

"If you have something to do, I will send my message to the people from the Wang family, Yuan family and Xiao family in Jiangnan scattered in Chang'an. I said that in three days I will hold a banquet to entertain them. Remember, you don't need to call the Xie family, but don't call the Xie family."

"The villain understands, let's do it now." Fan Jian nodded and left.

When he returned home, Li Xiang was the only one reading in the study. When he saw Gu Qing coming back, Li Xiang stood up and brought a chair for Gu Qing and asked, "Teacher, why did the court march westward?"

"Why did you suddenly ask about this?"

"Students don't understand." Li Xiang asked in a low voice: "As Brother Gu Xiao said, the focus in the future will be on the sea trade rather than on the Western trade route. The western expedition is for the commercial route. What's the point of the western expedition with the sea trade service?"

"How come it's meaningless?" Gu Qing continued to Li Xiang: "The West is far away for the Central Plains. Even if the chaos in the West has nothing to do with us, right?"

"Yes." Li Xiang nodded.

"Why don't you think about why Emperor Wu of Han wanted to retake the Hetao and Hexi Corridor, why Emperor First Emperor wanted to build the Great Wall, and why General Li Jing must retake Yinshan."

Li Xiang thought in confusion.

Gu Qing said to him patiently: "It's not for anything else, but for the sake of stability and stability. Now the West is in chaos, and the Roman expedition has reached the Great Food. Why can our Tang Dynasty be fearless? With Tubo, the Tang Dynasty soldiers arrived in Tubo, and there was a camp where they could get rest when they arrived in Tubo, so there was no need to worry about the supply line in the rear. However, once the Western army broke through Tubo, it made Tubo chaotic."

"Just like dominoes, there will be many chain effects. The fall of Tubo will lead to chaos in the entire Western Regions. Once chaos in the Western Regions, there will be a dangerous area west of Yumen Pass in the Central Plains. As long as there are enough troops, you can cross the Western Regions and come to the bottom of Yumen Pass."

"What is a domino?" Li Xiang asked in a low voice.

"Domino domino is like two trees that are very close to each other. When one tree is about to fall, it will fall next to another tree." Gu Qing continued: "In fact, there is nothing in the distant West. Just like that boy Gu Xiao said, it is really no longer important to have the Western trade route, but the importance of this barrier has always existed, just like Emperor Wu of Han has been trying to get the Hexi Corridor. In fact, the Hexi Corridor is not big, right?"

"Well, the Hexi Corridor is not big." Li Xiang nodded.

Putting the center of gravity of his body on the chair, Gu Qing said again: "The Huns on the grasslands during the reign of Emperor Wu of Han went south and plundered everywhere. The Hexi Corridor was just a very small territory for the Huns. But Emperor Wu of Han took down such a small place as the Hexi Corridor, so do you know why?"

Li Xiang shook her head.

Gu Qing looked at him and said, "Although the Hexi Corridor is not a big land, it is a very important place. It connects the Western Regions and the grasslands, like a small path that can penetrate directly into the hinterland of the Huns. As long as the Huns are about to fight, Emperor Wu of Han can send troops through the Hexi Corridor, and penetrate directly into the hinterland of the Huns from the Hexi Corridor, forming a counterattack with a horn. After taking down the Hexi Corridor, Emperor Wu of Han sent troops to the Huns in several battles."

Gu Qing said again: "It's like the Great Wall, like Yinshan, and Tubo, and their functions are the same. They are in a very special position. If these positions are in the hands of the enemy, it is very dangerous for the Central Plains. It's like the Hexi Corridor. The Hexi Corridor is the key to Emperor Wu of Han defeating the Huns. But if the Hexi Corridor is in the hands of the Huns, the Huns can form an encirclement of the Central Plains, making it impossible for the Central Plains to fight back."
